Instrument used for measuring wind velocity is known as:
  • Hydrometer
  • Pyranometer
  • Altimeter
  • Anemometer
The correct answer is d) Anemometer. Explanation: d) Anemometer: An anemometer is a device used for measuring wind speed and direction (though some anemometers measure only speed, while direction is measured by a wind vane). The term comes from the Greek word "anemos," meaning wind. Common types include cup anemometers and vane anemometers. Let's look at why the other options are incorrect: a) Hydrometer: A hydrometer is an instrument used for measuring the relative density (or specific gravity) of liquids. b) Pyranometer: A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface. It measures the power of sunlight. c) Altimeter: An altimeter is an instrument used to measure the altitude of an object above a fixed level (e.g., sea level).
A fodder and pasture legume
  • Glyricidia
  • Stylosanthus
  • Cowpea
  • Sesbania
The best answer among the choices, specifically known for both fodder and as a significant component of improved pastures, is b) Stylosanthes. Explanation: b) Stylosanthes (often called Stylo): This genus includes several species (e.g., Stylosanthes hamata, Stylosanthes guianensis, Stylosanthes scabra) that are widely used as tropical and subtropical pasture legumes. They are valued for their ability to improve soil fertility (nitrogen fixation), provide nutritious forage for livestock (both for grazing and as cut fodder/hay), and their tolerance to drought and low-fertility soils. They are a cornerstone of many improved pasture systems. Let's look at the other options: a) Glyricidia (Gliricidia sepium): This is a leguminous tree widely used as a fodder tree (leaves are cut and fed to animals) and for green manure, living fences, and shade. While excellent fodder, it's a tree, not typically a "pasture" component in the sense of a grazed field, though animals might browse it. c) Cowpea (Vigna unguiculata): Cowpea is a versatile legume. Its grains are used for human food, and the entire plant (vines and leaves) can be used as highly nutritious fodder for livestock. It can be grazed, but it's often grown as a specific fodder crop to be cut or as a dual-purpose crop. It's not as perennial or as commonly used for establishing long-term pastures as Stylosanthes. d) Sesbania (e.g., Sesbania sesban, Sesbania grandiflora): Similar to Glyricidia, Sesbania species are leguminous trees or shrubs often used for fodder (leaves and tender stems), green manure, and other purposes. They are more of a browse or cut-and-carry fodder source than a primary pasture legume for grazing. While all listed plants can be used as fodder and are legumes, Stylosanthes is most specifically recognized and widely utilized as a pasture legume for direct grazing, in addition to being used as cut fodder.
Plasmodiophora brassicae causes the club root disease of crucifers which can be controlled by
  • Raising pH of soil
  • Decreasing pH of soil
  • Both A and B
  • None of these
Plasmodiophora brassicae, the causal agent of club root disease of crucifers, thrives in acidic soil conditions. Therefore, to control the disease, the pH of the soil should be raised. So the answer is: (a) Raising pH of soil Explanation: Club root is generally more severe in acidic soils (pH below 6.5). Raising the soil pH to slightly alkaline levels (e.g., pH 7.0-7.5, and sometimes even higher up to 7.8, though care must be taken not to induce nutrient deficiencies) by applying lime (calcium carbonate, hydrated lime, etc.) makes the soil environment less favorable for the pathogen's spore germination and infection process. This is a common cultural control practice for managing club root. Decreasing the pH would exacerbate the problem.
Linseed is grown in
  • Kharif
  • Summer
  • Rabi
  • All seasons
The correct answer is b) Rabi. Explanation: Linseed (Alsi) is predominantly a Rabi season crop in India. It is sown in October-November after the monsoon season recedes, when temperatures start to cool down. It requires cool weather during its vegetative growth phase and relatively dry, sunny weather during its flowering and maturity stages. Harvesting usually takes place in February-March or early April. Let's consider why the other options are less suitable: a) Kharif: The Kharif season (monsoon season) is generally too wet and humid for optimal linseed cultivation, making it prone to diseases. c) Summer: The extreme heat of the Indian summer season is not conducive to linseed growth; it prefers cooler temperatures. d) All seasons: Linseed has specific climatic requirements (cool and moderately dry) that are best met during the Rabi season in most parts of India where it is grown. It cannot be grown effectively in all seasons. Therefore, linseed is characteristically grown as a Rabi crop
CCC has been found to
  • Slow down the vegetative growth
  • Enhance the root growth
  • Interfere with the biosynthesis of gibberllic acid
  • All the above
The correct answer is d) All the above. Explanation: CCC (Chlormequat Chloride), often sold under the trade name Cycocel, is a plant growth retardant. Its effects are: c) Interfere with the biosynthesis of gibberellic acid: This is its primary mode of action. CCC inhibits the enzymes involved in the early steps of gibberellin (GA) biosynthesis. Gibberellins are plant hormones that promote cell elongation, and thus stem elongation. a) Slow down the vegetative growth: By inhibiting gibberellin synthesis, CCC reduces cell elongation. This leads to shorter, sturdier stems, more compact plants, and generally slows down the overall rate of vegetative growth. This can be beneficial in preventing lodging (falling over) in cereal crops and producing more compact ornamental plants. b) Enhance the root growth: When shoot growth is retarded by CCC, the plant often reallocates resources. More carbohydrates and energy may be diverted to the root system, leading to an increased root-to-shoot ratio and potentially enhanced root growth and development. This can make plants more resistant to drought stress. Therefore, all the listed effects are characteristic of CCC application.
It has been observed that propanil herbicide interfered with ATP generation and electron transport of mitochondria in
  • Wheat
  • Barley
  • Sorghum
  • Green gram
Propanil's primary mode of action is the inhibition of photosynthesis at Photosystem II. However, like many herbicides that cause significant physiological stress, secondary effects can occur, including impacts on mitochondrial function. Based on available literature and extension resources (e.g., some university extension publications on herbicide modes of action), it has been noted that Propanil can also interfere with mitochondrial electron transfer and ATP synthesis in susceptible plants. Among the options provided, c) Sorghum is a plant where such effects have been reported in literature discussing Propanil's broader physiological impacts beyond just PSII inhibition. For instance, some resources mention that propanil can inhibit mitochondrial respiration in plants like sorghum and spinach. Therefore, based on available information, the answer is c) Sorghum. It's important to note: The primary and most well-understood mode of action of Propanil is as a Photosystem II inhibitor. Effects on mitochondria are often considered secondary or contributing factors to the overall phytotoxicity in susceptible species. Rice (not an option here) is tolerant to Propanil because it can rapidly metabolize the herbicide before significant damage to either photosynthesis or mitochondrial function occurs. The interference would be more pronounced and damaging in susceptible weeds or crops.
The percent of incoming radiation that is reflected is called
  • Geotemperature
  • Albedo
  • Solarization
  • None of these
The correct answer is b) Albedo. Explanation: b) Albedo: Albedo is a measure of the reflectivity of a surface. It is defined as the ratio of reflected radiation from the surface to the incident radiation upon it. It is often expressed as a percentage or a decimal (e.g., an albedo of 0.3 means 30% of the incoming radiation is reflected). Surfaces like fresh snow have a high albedo (reflecting a lot of light), while dark surfaces like asphalt have a low albedo (absorbing a lot of light). Let's look at the other options: a) Geotemperature: This refers to the temperature of the Earth, particularly its internal heat or the temperature of the ground. It's not related to reflection of radiation. c) Solarization: This term can have a few meanings: In photography, it's an effect of image reversal due to extreme overexposure. In agriculture/horticulture, it refers to soil solarization, a method of sterilizing soil using solar heat trapped under clear plastic. In plant physiology, it can refer to photoinhibition or damage to plants from excessive light. None of these relate directly to the percentage of reflected radiation. Therefore, albedo is the correct term for the percent of incoming radiation that is reflected.
Pendimethalin is following kind of herbicide
  • Post emergence
  • Pre-emergence
  • Soil-incorporated
  • None of these
The correct answer is b) Pre-emergence. Explanation: Pendimethalin is a widely used selective herbicide that belongs to the dinitroaniline chemical family. Its primary mode of application and action is pre-emergence. This means it is applied to the soil before weed seeds germinate or before the weeds emerge from the soil surface. Pendimethalin works by inhibiting cell division and cell elongation in the root and shoot tips of susceptible emerging weed seedlings. It forms a chemical barrier on the soil surface, and as weeds germinate and try to grow through this barrier, they absorb the herbicide and die. Let's look at the other options: a) Post-emergence: Post-emergence herbicides are applied after the weeds (and sometimes the crop) have already emerged. Pendimethalin has very little to no activity on already established weeds. c) Soil-incorporated: While some pre-emergence herbicides (especially volatile ones like trifluralin) require soil incorporation (mixing into the top few inches of soil) to be effective and prevent loss, pendimethalin is often applied as a surface pre-emergence treatment. Light irrigation or rainfall after application helps to move it into the weed germination zone and activate it. While it can be lightly incorporated in some situations, its primary classification is pre-emergence, and it doesn't strictly require incorporation like some other dinitroanilines. It's more about its timing of action relative to weed emergence. Therefore, pendimethalin is fundamentally a pre-emergence herbicide.
Relative growth rate of crop is equal to a
  • Net assimilation rate x leaf area
  • Net assimilation rate x leaf area duration
  • Net assimilation rate x leaf area index
  • None of these
The correct answer is a) Net assimilation rate x leaf area ratio. Explanation: The Relative Growth Rate (RGR) of a crop is a measure of the increase in plant mass per unit of plant mass already present, per unit of time. It can be broken down into two components: Net Assimilation Rate (NAR): This is a physiological component. It represents the net gain in dry weight per unit of leaf area per unit of time (e.g., g m⁻² day⁻¹). It reflects the efficiency of the leaves in producing new biomass through photosynthesis, minus what is lost through respiration. NAR = (1/Leaf Area) x (dW/dt) (where W is plant dry weight, t is time) Leaf Area Ratio (LAR): This is a morphological component. It represents the amount of leaf area a plant deploys per unit of its total dry weight (e.g., m² g⁻¹). It indicates how much of the plant's biomass is invested in photosynthetic machinery (leaves). LAR = Leaf Area / Plant Dry Weight When you multiply these two: RGR = NAR x LAR Units: (g m⁻² day⁻¹) x (m² g⁻¹) = g g⁻¹ day⁻¹ (or simply day⁻¹, as g/g cancels out) This formula shows that a plant's relative growth rate depends on both how efficiently its leaves are working (NAR) and how much leaf area it has relative to its total size (LAR). Let's look at why other options are incorrect: b) Net assimilation rate x leaf area duration (LAD): LAD is the leaf area maintained over a period. Multiplying NAR by LAD would give you an estimate of total biomass produced over that period, not a rate of relative growth. c) Net assimilation rate x leaf area index (LAI): LAI is leaf area per unit ground area. Multiplying NAR by LAI gives you the Crop Growth Rate (CGR), which is the rate of dry matter accumulation per unit of ground area, not per unit of plant biomass.
Retting is process by which
  • The poor fibre stalk is sorted out
  • The fibres in the bark get loosened and separated from woody stalk
  • The good quality fibres are sorted out
  • Fibres are differentiated into various retted groups
The correct answer is b) The fibres in the bark get loosened and separated from woody stalk. Explanation: Retting is a crucial process in the extraction of bast fibers (fibers collected from the phloem or "bark" of certain plants) like jute, flax, hemp, and kenaf. The process involves using moisture and microorganisms (bacteria and fungi) or chemicals to break down the pectins and other gummy substances that bind the fibers to the woody core (xylem) of the stalk and to each other. This decomposition: Loosens the fibers within the bark. Allows for easier separation of the long fiber bundles from the non-fibrous parts of the stalk, particularly the central woody core. Let's look at why the other options are less accurate: a) The poor fibre stalk is sorted out: Sorting of stalks might happen before retting, but retting itself is the treatment process, not the sorting. c) The good quality fibres are sorted out: Sorting of fibers for quality usually happens after retting and extraction, during processes like scutching and hackling. d) Fibres are differentiated into various retted groups: This sounds like a classification step that might occur after retting, perhaps based on the quality or success of the retting, rather than defining the process itself. Therefore, retting is specifically the process that facilitates the separation of fibers by loosening them from the rest of the plant stalk.
The crop that has highest area in world is
  • Rice
  • Wheat
  • Sorghum
  • Millets
The crop that has the highest area cultivated in the world is b) Wheat. Explanation: While rice and maize (corn) are also incredibly important global staples with vast production volumes, wheat typically occupies the largest land area globally. Wheat: It is highly adaptable to a wide range of climates, from temperate to subtropical, and even some semi-arid regions. It's a staple food for a significant portion of the world's population and is grown across North America, Europe, Asia (including China and India), Australia, and parts of South America and Africa. Rice: Primarily grown in tropical and subtropical regions, especially in Asia, where it's a fundamental staple. Its cultivation is often intensive and requires significant water, which limits its geographical spread compared to wheat. Maize (Corn - not an option here, but for context): Also has a very large cultivated area, often competing closely with wheat and rice. It's used for food, feed, and industrial purposes. Sorghum & Millets: These are crucial crops, especially in arid and semi-arid regions of Africa and Asia, due to their drought tolerance. However, their total global cultivated area is less than that of wheat, rice, or maize. According to data from the Food and Agriculture Organization of the United Nations (FAO), wheat consistently has one of the largest, if not the largest, harvested areas worldwide
Among the following crops, S uptake is highest by
  • Rice
  • Mustard
  • Soybean
  • Chick pea
The crop that generally has the highest sulfur (S) uptake among the given options is b) Mustard. Explanation: Oilseed Crops: Oilseed crops, in general, have a relatively high requirement for sulfur. Sulfur is essential for the synthesis of sulfur-containing amino acids (methionine, cysteine, cystine), which are precursors to proteins and also play a role in oil synthesis. Brassica Family (Cruciferae): Mustard belongs to the Brassica family (e.g., rapeseed, cabbage, cauliflower). Plants in this family have a particularly high demand for sulfur. This is because, in addition to its role in amino acids and oil synthesis, sulfur is a key component of glucosinolates. Glucosinolates are secondary metabolites characteristic of Brassica plants, contributing to their pungent flavor and defense mechanisms. The synthesis of these compounds requires a significant amount of sulfur. Comparing with other options: a) Rice: As a cereal, rice has a moderate sulfur requirement, generally lower than oilseeds and especially lower than Brassicas. c) Soybean: Being a legume and an oilseed, soybean has a significant S requirement for protein synthesis (rich in S-containing amino acids) and oil production. Its S uptake is high, but typically less than that of Brassica oilseeds like mustard under optimal conditions. d) Chickpea: As a pulse (legume), chickpea requires sulfur for protein synthesis and nitrogen fixation. Its S requirement is moderate, generally lower than oilseeds. General Order of S Requirement/Uptake (Highest to Lowest among options): Mustard > Soybean > Chickpea / Rice (these two can be similar or vary based on yield and specific conditions, but both are lower than mustard and soybean). Therefore, due to its nature as a Brassica oilseed and the production of sulfur-rich glucosinolates, mustard typically exhibits the highest sulfur uptake among the choices provided.
Consumptive use of water is very close to
  • Water requirement
  • Evapotranspiration
  • Transpiration ratio
  • Irrigation requirement
The correct answer is b) Evapotranspiration. Explanation: Consumptive Use (CU) of water by a crop refers to the total amount of water used by the plant for its metabolic processes (building plant tissue) and the water lost through transpiration from the plant surfaces, plus the water evaporated from the adjacent soil surface or from precipitation intercepted by the plant foliage. Evapotranspiration (ET) is the sum of two processes: Evaporation (E): Water lost as vapor from the soil surface and water intercepted on plant surfaces. Transpiration (T): Water absorbed by plant roots, transported through the plant, and lost as vapor from plant leaves and stems (primarily through stomata). The water used by plants for their metabolic processes (building tissues) is a very small fraction (typically less than 1-5%) of the total water taken up and transpired. Therefore, for practical purposes in agriculture, hydrology, and irrigation management: Consumptive Use (CU) ≈ Evapotranspiration (ET) Let's look at the other options: a) Water Requirement (WR): Water Requirement is broader. It includes the consumptive use (ET) plus water lost during application (application losses) plus any water needed for special operations like leaching salts. So, WR = CU + Application Losses + Water for Special Operations. c) Transpiration Ratio (TR): This is the ratio of the mass of water transpired to the mass of dry matter produced by the plant. It's a measure of water use efficiency, not the total amount of water consumed. d) Irrigation Requirement (IR): This is the amount of water that needs to be supplied through irrigation to meet the crop's water requirement after accounting for effective rainfall and soil moisture contribution. IR = WR - (Effective Rainfall + Soil Moisture Contribution). Therefore, consumptive use of water is most closely approximated by, and often used interchangeably with, evapotranspiration.
Groundnut the chief source of vegetable oil in India, originated in
  • China
  • West Africa
  • Brazil
  • United States of America
The correct answer is c) Brazil. Explanation: Groundnut (Arachis hypogaea L.), also known as peanut, is believed to have originated in South America, specifically in the region encompassing parts of Brazil, Bolivia, Paraguay, and Argentina. Archaeological evidence and genetic studies point to this region as the center of diversity for wild Arachis species and the likely area where the cultivated groundnut was first domesticated thousands of years ago. From South America, it spread to other parts of the Americas and was later introduced to Africa, Asia (including India), and Europe by Portuguese and Spanish explorers during the 16th and 17th centuries. Let's look at the other options: a) China: China is a major producer and consumer of groundnuts today, but it's an area of secondary introduction. b) West Africa: West Africa is also a significant region for groundnut cultivation and consumption, but like China, it received the crop from the Americas. d) United States of America: The USA is a notable producer, but groundnuts were introduced there from their South American origin.
Which crop is used for producing both the vegetable oil and fiber
  • Castor
  • Mesta
  • Linseed
  • Safflower
The crop that is well-known for producing both vegetable oil and fiber is c) Linseed. Explanation: c) Linseed (Linum usitatissimum): Vegetable Oil: The seeds of linseed (also known as flaxseed) are crushed to produce linseed oil. This oil is edible (often marketed as flaxseed oil for its health benefits) and also has significant industrial uses (e.g., in paints, varnishes, linoleum). Fibre: The stem of the flax plant yields flax fiber, which is one of the oldest known textile fibers and is used to make linen. Let's look at the other options: a) Castor (Ricinus communis): Vegetable Oil: Castor seeds produce castor oil, which is a non-edible vegetable oil with numerous industrial and medicinal applications. Fibre: Castor is not typically grown for fiber. b) Mesta (Hibiscus cannabinus - Kenaf, or Hibiscus sabdariffa - Roselle): Vegetable Oil: The seeds of Kenaf and Roselle do contain oil, and it can be extracted. Kenaf seed oil is edible. Fibre: Mesta (especially Kenaf) is primarily cultivated as a fiber crop, producing bast fibers similar to jute, used for making rope, twine, and coarse fabrics. While Mesta does produce both, Linseed is more classically and widely recognized for significant commercial production of both oil and fiber on a global scale. d) Safflower (Carthamus tinctorius): Vegetable Oil: Safflower seeds are a source of edible vegetable oil. Fibre: Safflower is not grown for fiber. Its flowers were historically used for dye. Considering the prominent and well-established dual use for both commercially significant oil and fiber, Linseed is the best answer.
G herbaccum is a species of
  • Jute
  • Tobacco
  • Mentha
  • Cotton
The correct answer is d) Cotton. Explanation: G. herbaceum is the botanical name for Gossypium herbaceum. Gossypium is the genus for cotton. Gossypium herbaceum, also known as Levant cotton or Arabian cotton, is one of the Old World cotton species. It is cultivated in parts of Asia and Africa. Let's look at the other options' genera: a) Jute: Belongs to the genus Corchorus (e.g., Corchorus capsularis, Corchorus olitorius). b) Tobacco: Belongs to the genus Nicotiana (e.g., Nicotiana tabacum, Nicotiana rustica). c) Mentha: Mentha is the genus name itself for various mint species (e.g., Mentha piperita - peppermint, Mentha spicata - spearmint). Therefore, G. herbaceum is a species of Cotton.
A crop grown in pure stand at optimum population is
  • Sole crop
  • Mono crop
  • Main crop
  • Lease crop
The correct answer is a) Sole crop. Explanation: a) Sole crop: This term refers to growing a single crop species or variety alone in a pure stand at a normal or optimum population density within a specific field or area at a particular time. This perfectly matches the description "A crop grown in pure stand at optimum population." Let's look at the other options: b) Monocrop (or Monoculture): Monocropping refers to the agricultural practice of growing the same single crop on the same land year after year. While a field under monocropping at any given time would be a pure stand, the term "monocrop" emphasizes the repetitive cultivation over time, rather than just the state of the field at one point. "Sole crop" is more precise for the given definition. c) Main crop: This term is typically used in the context of intercropping or mixed cropping systems, where it refers to the primary crop among two or more crops grown together. The question describes a pure stand, so this doesn't fit. d) Lease crop: This term refers to a crop grown on land that is leased by the farmer, relating to land tenure rather than the cropping pattern itself. Therefore, sole crop is the most accurate term.
Medium range weather forecasting is valid up to
  • 10 days
  • 3 days
  • 30 days
  • 7 days
The correct answer is a) 10 days. Explanation: Weather forecasts are generally categorized by their time horizon: Short-range weather forecasting: Typically valid for up to 48-72 hours (2-3 days). These are generally the most accurate. Medium-range weather forecasting: Valid from 3 days up to 10 days (sometimes extended to 15 days by some agencies, but 10 days is a common upper limit for reliable operational forecasts). The accuracy decreases as the forecast period extends. Extended-range weather forecasting: Covers periods from about 10 days up to 30 days (or roughly a month). These are often presented as outlooks for general trends rather than precise daily weather. Long-range weather forecasting (Seasonal outlooks): Covers periods from a month to several seasons ahead. These predict deviations from climatic averages (e.g., warmer than average, drier than normal). Therefore, medium-range weather forecasting is generally considered valid up to 10 days.
An amino acid accumulation observed in plants after the moisture stress and considered as a good indicator of moisture stress is known as
  • Abscicic acid
  • Proline
  • Betane
  • Ethylene
The correct answer is b) Proline. Explanation: Proline is an amino acid that is widely known to accumulate in many plant species in response to various environmental stresses, particularly moisture stress (drought) and salinity. Functions of Proline Accumulation: Osmotic Adjustment: Proline acts as a compatible solute or osmolyte, helping to maintain cell turgor by lowering the water potential within cells without interfering with cellular metabolism. Protection of Cellular Structures: It can help stabilize proteins and membranes, protecting them from damage caused by dehydration. Scavenging Reactive Oxygen Species (ROS): It may play a role in mitigating oxidative stress by scavenging free radicals. Source of Carbon and Nitrogen: Upon stress relief, accumulated proline can be rapidly catabolized, providing carbon and nitrogen for recovery growth. Indicator of Moisture Stress: Due to its significant accumulation under drought conditions, the level of proline in plant tissues is often used as a biochemical marker or indicator of the intensity of moisture stress experienced by the plant. Let's look at the other options: a) Abscisic acid (ABA): ABA is a plant hormone that plays a crucial role in mediating plant responses to stress, including stomatal closure during drought. It does accumulate under moisture stress and is a good indicator, but it is a hormone, not an amino acid. c) Betaine (Glycine Betaine): Glycine betaine is another important compatible solute (an osmoprotectant) that accumulates in many plants under stress conditions. However, it is a quaternary ammonium compound, not an amino acid (though it's derived from glycine). d) Ethylene: Ethylene is a gaseous plant hormone involved in various stress responses, including senescence and abscission. Its production can increase under stress, but it's a hormone, not an amino acid accumulating for osmotic purposes in the same way as proline. Therefore, proline is the amino acid specifically known for its significant accumulation as an indicator and response to moisture stress.
Situation when a major pest is suppressed and continues to be suppressed by a tactic but is replaced but is replaced by another pest, previously with minor status
  • Replacement
  • Secondary pest outbreak
  • Both A and B
  • Hormoligosis
The correct answer is (C) Both A and B. Explanation: (A) Replacement (or Pest Replacement / Species Replacement): This term specifically describes the ecological phenomenon where the suppression or elimination of a dominant pest species allows another, previously less significant species (a minor pest), to increase in numbers and become a new, economically important pest problem. The original major pest is "replaced" by the new one. (B) Secondary Pest Outbreak: This is a very common mechanism leading to pest replacement. A secondary pest is an organism that is normally present but kept at low, non-damaging population levels by natural enemies (predators, parasitoids, pathogens). When a broad-spectrum pesticide or another tactic is used to control a primary (major) pest, it can also kill these natural enemies. With their natural controls removed, the secondary pest population can "outbreak" or "flare up," becoming a major problem itself. The situation described in the question perfectly fits both definitions: The original major pest is suppressed. A previously minor pest "replaces" it as the main issue. This replacement often occurs because the tactic used against the major pest also inadvertently affects the factors (like natural enemies) that were keeping the minor pest in check, leading to its outbreak (a secondary pest outbreak). Therefore, the situation is a "replacement," and a "secondary pest outbreak" is a common way this replacement manifests. (D) Hormoligosis: This refers to the stimulatory effect of sub-lethal doses of a stressor (like a pesticide) on an organism, sometimes leading to increased growth, reproduction, or longevity. This is a different phenomenon than what is described.
Which of the following is a monophagous pest
  • Root knot nematode
  • Diamond back moth
  • Helicoverpa armigera
  • Rice stem borer
The correct answer is (D) Rice stem borer. Explanation: Monophagous pest: An insect pest that feeds on only one plant species or a very narrow range of closely related plant species (often within the same plant genus). Let's analyze the options: (A) Root knot nematode (Meloidogyne spp.): These are highly polyphagous, meaning they have a very wide host range, attacking hundreds of different plant species across many families. (B) Diamond back moth (Plutella xylostella): This pest is oligophagous. It specializes on plants in the family Brassicaceae (Cruciferae), such as cabbage, cauliflower, broccoli, mustard, etc. While specialized, it still feeds on a family of plants, not just one species. (C) Helicoverpa armigera (Gram pod borer/American bollworm/Cotton bollworm): This is a classic example of a polyphagous pest, attacking a vast array of unrelated crops like cotton, pulses, tomatoes, maize, sorghum, etc. (D) Rice stem borer (e.g., Yellow stem borer - Scirpophaga incertulas): These insects are primarily pests of rice (Oryza sativa). While some species might occasionally feed on a few other wild grasses, their main host and the plant they cause significant economic damage to is rice. This makes them the best example of a monophagous (or very narrowly oligophagous, focusing heavily on one primary host) pest among the given options. Therefore, the Rice stem borer is the most fitting example of a monophagous pest.
The downward curling of leaves and “V” shaped yellowing at the tip in groundnut is an indicator of
  • Amsacta moorei
  • Empoasca devestans
  • Empoasca kerri
  • Frankliniella schultzei
The correct answer is (C) Empoasca kerri. Explanation: The symptoms described – downward curling of leaves and "V" shaped yellowing at the tip (often starting at the margins and progressing inwards) – are characteristic of hopperburn in groundnut. This damage is caused by leafhoppers. Let's analyze the options: (A) Amsacta moorei (Red Hairy Caterpillar): This is a defoliating caterpillar. It chews on leaves, causing holes or complete defoliation, not the specific curling and V-shaped yellowing. (B) Empoasca devestans (now often referred to as Amrasca biguttula biguttula in some regions, a cotton jassid/leafhopper): While this leafhopper can affect groundnut and cause hopperburn-like symptoms, Empoasca kerri is more specifically and commonly associated with these distinct symptoms in groundnut in many regions of India. (C) Empoasca kerri (Groundnut Leafhopper or Jassid): This is a well-known leafhopper pest of groundnut. Both nymphs and adults suck sap from the undersurface of the leaves. While feeding, they inject toxic saliva into the plant tissues. This results in: Downward curling of leaf margins. Yellowing of the leaf tips and margins, often progressing in a characteristic "V" shape. This is known as hopperburn. Severe infestation can lead to bronzing, drying of leaves, and stunting of the plant. (D) Frankliniella schultzei (Common Blossom Thrips): Thrips feed by piercing and sucking cell contents, primarily in flowers and young leaves. Damage on leaves typically appears as silvery or whitish patches (stippling), leaf distortion, and sometimes curling. While they can cause significant damage and transmit viruses (like Groundnut Bud Necrosis Virus), the distinct "V-shaped yellowing at the tip" is more typical of hopperburn. Therefore, the combination of downward leaf curling and "V" shaped yellowing at the tip is a strong indicator of infestation by Empoasca kerri in groundnut.
A single Helicoverpa armigera feed on how many pod before reaching maturity
  • 10-20
  • 30-40
  • 50-60
  • 70-80
The correct answer is (B) 30-40. Explanation: Helicoverpa armigera is a highly voracious and destructive pest. A single larva, during its development through several instars before reaching maturity and pupating, can cause significant damage. While the exact number can vary depending on factors like the host crop, pod size, environmental conditions, and the specific instar of the larva, it is well-documented that a single larva can damage multiple pods. For crops like chickpea (gram), it is often cited that a single Helicoverpa armigera larva can damage 30 to 40 pods during its larval period. It typically bores into a pod, consumes the developing seeds, and then may move to another pod. Considering the options: (A) 10-20: This is likely an underestimate for such a damaging pest over its entire larval life. (B) 30-40: This range aligns well with many reports on the feeding capacity of H. armigera on pod-bearing crops. (C) 50-60: This might be on the higher side for an average, though possible under certain conditions with smaller pods or a longer larval period. (D) 70-80: This is generally too high for a single larva. Therefore, the most commonly accepted and realistic range for the number of pods a single Helicoverpa armigera larva feeds on before reaching maturity is 30-40.
The scientific name of sugarcane top shoot borer is
  • Chilo infuscatellus
  • Scirpophaga nivella
  • Chilo auricilius
  • Acigona steniella
The correct answer is (B) Scirpophaga nivella (often now referred to as Scirpophaga excerptalis). Explanation: (A) Chilo infuscatellus: This is the scientific name for the Early Shoot Borer or Shoot Borer of sugarcane. It attacks young shoots causing dead hearts. (B) Scirpophaga nivella (now more commonly known as Scirpophaga excerptalis): This is the scientific name for the Top Borer or Top Shoot Borer of sugarcane. The larva bores into the top portion of the cane, affecting the growing point and causing a characteristic "bunchy top" symptom. (C) Chilo auricilius: This is the scientific name for the Stalk Borer or Gold-fringed Stalk Borer of sugarcane. It primarily attacks the stalks/internodes. (D) Acigona steniella (now often classified as Chilo partellus): Chilo partellus is the Spotted Stem Borer, a major pest of sorghum and maize, though it can also attack sugarcane. It's a stem borer, not specifically the "top shoot borer." Therefore, the scientific name for the sugarcane top shoot borer is Scirpophaga nivella (or Scirpophaga excerptalis).
Supply chain stage refers to the steps taken
  • To deliver food from the farmer to the consumer
  • To deliver food from its input supplier to the farmer
  • To deliver food from its input supplier to the consumer
  • To deliver food from the farmer to the distribution
The most comprehensive and accurate answer is: c) To deliver food from its input supplier to the consumer Here's why: A complete supply chain encompasses all steps from the very beginning (raw materials or inputs) to the final end-user. Input suppliers (e.g., seed companies, fertilizer manufacturers, equipment providers) are the starting point for agricultural production. The farmer uses these inputs to produce food. The food then moves through various stages (processing, distribution, retail) until it reaches the consumer. Let's look at why the other options are less complete: (a) To deliver food from the farmer to the consumer: This is a significant part of the supply chain, but it omits the crucial upstream stage of input supply to the farmer. (b) To deliver food from its input supplier to the farmer: This is only the very first part of the supply chain. (d) To deliver food from the farmer to the distribution: This is only a segment of the supply chain, missing processing, retail, and the end consumer. Therefore, option (c) best describes the entire set of steps involved in a food supply chain.
Dissemination of product details viz, price, quantity, locality, etc through multi media is known as__________
  • Physical Movement Functions
  • Facilitative Functions
  • Exchange Functions
  • Management Functions
The correct answer is b) Facilitative Functions. Here's why: Facilitative Functions in marketing are those activities that make the exchange process (buying and selling) smoother and more efficient. Disseminating market information, such as product details (price, quantity, locality), is a crucial facilitative function. It helps buyers and sellers make informed decisions. Let's look at the other options: a) Physical Movement Functions: These relate to the actual handling and transportation of goods, like storage, transportation, and processing. c) Exchange Functions: These are the core activities of buying and selling. While information dissemination supports exchange, it's not the exchange itself. d) Management Functions: This is a broader category referring to planning, organizing, directing, and controlling marketing activities. While disseminating information is part of managing a marketing strategy, the act itself falls under facilitative functions. Therefore, the dissemination of product details through multimedia is a form of market intelligence or information dissemination, which is a key facilitative function.
Market for flower is _____________
  • Specialized Markets
  • Secular market
  • Rural Market
  • Village market
The best answer is a) Specialized Markets. Here's why: Specialized Markets: These are markets that deal in a specific commodity or a narrow range of commodities that often require particular handling, knowledge, or infrastructure. The flower market fits this description well: Flowers are highly perishable. They require specific handling and often temperature-controlled environments (cold chains). There are specific grading standards. There are dedicated auction houses and wholesale markets specifically for flowers (e.g., Aalsmeer in the Netherlands, or major flower mandis in India like in Bangalore, Pune, Kolkata). Let's look at the other options: b) Secular market: This term is not typically used to classify markets based on the commodity type. "Secular" usually refers to long-term trends (secular trend) or things not related to religion. c) Rural Market: While flowers can be grown and sold in rural areas, a "rural market" is defined by its location and the population it serves, not specifically by the commodity. A rural market could sell many things. The main, organized markets for flowers, especially wholesale, are often in urban or peri-urban areas. d) Village market: Similar to a rural market, this is a very local market. While some flowers might be sold here, it doesn't represent the broader, organized market for flowers which involves specialized wholesale and retail channels. Therefore, because of the unique characteristics of flowers and the specific infrastructure and practices involved in their trade, "Specialized Markets" is the most appropriate classification.
Management decisions, which involve lasting effects, are known as
  • Strategic planning
  • Marketing decisions
  • Operational decisions
  • Administrative decisions
The correct answer is a) Strategic planning. Here's why: Strategic planning involves making high-level decisions about an organization's overall direction, long-term goals, and how it will position itself to achieve those goals. These decisions inherently have lasting effects because they shape the future of the organization for years to come. Examples include entering new markets, developing new core product lines, or major mergers and acquisitions. Let's look at the other options: b) Marketing decisions: While some marketing decisions (like branding) can have long-term effects, many are more tactical and can be adjusted (e.g., specific advertising campaigns, pricing promotions). Strategic marketing decisions would fall under the umbrella of strategic planning. c) Operational decisions: These are day-to-day decisions related to the efficient functioning of the organization (e.g., production schedules, inventory levels). They are generally short-term and, while important, don't typically have the same profound, lasting effects as strategic decisions. d) Administrative decisions: These often relate to policies, procedures, and the internal workings of an organization. While some policies can have long-term implications, the term "administrative decisions" usually refers to more routine or procedural matters rather than fundamental directional choices with significant lasting effects. Therefore, decisions that involve lasting effects are best characterized as part of strategic planning.
The organizational features of a market are called _____________.
  • Market performance
  • Market structure
  • Market conduct
  • Marketing Channel
The correct answer is b) Market structure. Market structure refers to the organizational characteristics of a market that influence the nature of competition and pricing. Key elements of market structure include: The number and size distribution of buyers and sellers The degree of product differentiation The ease of entry into and exit from the market The extent of vertical integration These are all "organizational features" that define how a market is set up. Let's briefly look at why the other options are incorrect: a) Market performance: This refers to the results or outcomes of market activity, such as efficiency, price levels, profitability, and innovation. c) Market conduct: This describes the behavior of firms in a market, such as their pricing strategies, advertising, and research and development efforts. d) Marketing Channel: This refers to the specific path or route through which goods and services travel from the producer to the consumer (e.g., wholesaler, retailer). While part of how a market functions, "market structure" is a broader term encompassing the overall organizational setup.
Which market types has a large number of firms that sell similar products but slightly different?
  • Oligopsony
  • Perfect competition
  • Oligopoly
  • Monopolistic competition
The correct answer is d) Monopolistic competition. Here's why: Monopolistic Competition: This market structure is characterized by: A large number of firms. Differentiated products: The products are similar but not identical. Firms compete on factors like branding, quality, design, location, or service, creating perceived differences in the minds of consumers. Relatively easy entry and exit. Let's look at the other options: a) Oligopsony: This market has many sellers but only a few buyers. The product can be homogeneous or differentiated, but the defining feature is the buyer side. b) Perfect competition: This market has a very large number of firms selling identical (homogeneous) products. There is no product differentiation. c) Oligopoly: This market has a few large firms dominating the market. Products can be identical (e.g., steel) or differentiated (e.g., cars), but the key is the small number of dominant sellers. Therefore, the description "a large number of firms that sell similar products but slightly different" perfectly matches monopolistic competition.
Which of the following cultural practices is LEAST effective on its own for managing a severe infestation of perennial weeds like Johnson grass (Sorghum halepense) in a cotton field?
  • Deep summer ploughing
  • Crop rotation with a competitive smother crop
  • Hand weeding or hoeing
  • Solarization of the soil
Answer: (c) Hand weeding or hoeing Explanation: Perennial weeds like Johnson grass reproduce not only by seeds but also by extensive underground rhizomes (creeping rootstalks). (c) Hand weeding or hoeing: While these methods can remove the above-ground parts of perennial weeds, they often leave the rhizomes intact in the soil. The rhizomes can then quickly regrow, making these methods labor-intensive and often ineffective for long-term control of established perennial weed populations on their own. Breaking rhizomes into smaller pieces during hoeing can sometimes even exacerbate the problem by creating more propagules. (a) Deep summer ploughing: This can expose rhizomes to the hot sun, leading to desiccation and some level of control, especially if repeated. (b) Crop rotation with a competitive smother crop: Rotating cotton with a dense, fast-growing crop (like certain varieties of sorghum-sudan grass or cowpea) can help suppress perennial weeds by outcompeting them for resources. This, often combined with different herbicide options in the rotation crop, is a key strategy. (d) Solarization of the soil: This involves covering moist soil with clear plastic sheets during hot summer months. The trapped solar heat can kill weed seeds, seedlings, and some vegetative propagules like rhizomes in the upper soil layers. It is effective but may be more practical for smaller areas or high-value crops.  
The development of herbicide resistance in weed populations infesting cotton fields is most likely accelerated by
  • Rotating herbicides with different modes of action
  • Repeated and exclusive use of herbicides with the same mode of action
  • Integrating cultural weed control methods with chemical control
  • Using herbicides only at the recommended label rates
Answer: (b) Repeated and exclusive use of herbicides with the same mode of action Explanation: Herbicide resistance occurs when a small number of individual weeds within a population naturally possess genetic traits that allow them to survive a herbicide application that would normally kill them. (b) Repeated and exclusive use of herbicides with the same mode of action: This practice puts continuous selection pressure on the weed population. The susceptible individuals are killed, while the rare resistant individuals survive and reproduce. Over time, the proportion of resistant individuals in the population increases, leading to a field where the herbicide is no longer effective. This is the primary driver of herbicide resistance development. (a) Rotating herbicides with different modes of action: This is a key strategy to prevent or delay herbicide resistance. By using herbicides that kill weeds in different ways, it is less likely that a weed will be resistant to multiple modes of action simultaneously. (c) Integrating cultural weed control methods with chemical control: This is part of Integrated Weed Management (IWM) and also helps reduce the selection pressure for herbicide resistance by controlling weeds through multiple mechanisms. (d) Using herbicides only at the recommended label rates: While crucial for efficacy and safety, using the correct rate doesn't prevent resistance if the same mode of action is used repeatedly. In fact, using sub-lethal rates can sometimes accelerate resistance by allowing partially resistant individuals to survive.
Production of coffee powder from coffee seeds is an example of ?
  • Time utility
  • Form utility
  • Place utility
  • Possession utility
Production of coffee powder from coffee seeds is an example of form utility.
Bacteria can fix the nitrogen______
  • Pseudomonas
  • Staphylococcus
  • Rhizobium
  • Lactobacillus
The correct answer is c) Rhizobium. Rhizobium is a well-known genus of bacteria that lives in symbiotic relationships with leguminous plants (like peas, beans, clover). They form nodules on the roots of these plants and convert atmospheric nitrogen gas (N₂) into ammonia (NH₃), a form of nitrogen that plants can absorb and use. This process is called nitrogen fixation. Let's look at the other options: a) Pseudomonas: This is a diverse genus. Some species are involved in denitrification (converting nitrates back to N₂ gas), and others can be plant pathogens or beneficial to plants in other ways, but they are not primarily known as the key nitrogen fixers in the way Rhizobium is. b) Staphylococcus: These bacteria are commonly found on the skin and mucous membranes of humans and other animals. Some species can cause infections. They are not nitrogen fixers. d) Lactobacillus: These are lactic acid bacteria, known for their role in fermentation (e.g., making yogurt and cheese) and as probiotics. They are not nitrogen fixers.
What is the optimum temperature for nitrification?
  • 60°C
  • 50°C
  • 80°C
  • 30°C
The correct answer is D. 30°C. Nitrification is a biological process carried out by specific groups of bacteria (like Nitrosomonas and Nitrobacter). These bacteria are generally mesophilic, meaning they thrive in moderate temperatures. Optimal Range: The optimal temperature range for most nitrifying bacteria is typically between 25°C and 35°C. Activity Decrease: Below 15°C, their activity significantly slows down. Above 40°C, their activity also decreases, and higher temperatures can be lethal. Considering the options: A. 60°C: Too high, thermophilic range, would inhibit or kill most nitrifiers. B. 50°C: Too high, would significantly inhibit most nitrifiers. C. 80°C: Extremely high, definitely lethal to nitrifying bacteria. D. 30°C: Falls well within the optimal range for nitrification.
First antifungal agent is?
  • Nystatin
  • Tetracycline
  • Penicillin
  • Chloramfenical
The correct answer is A. Nystatin. Here's why: A. Nystatin: Discovered in 1950 by Elizabeth Lee Hazen and Rachel Fuller Brown, Nystatin was one of the very first effective antifungal antibiotics. It is derived from the bacterium Streptomyces noursei. Let's look at the other options: B. Tetracycline: This is a broad-spectrum antibacterial antibiotic, discovered in the late 1940s. It is not an antifungal. C. Penicillin: Discovered by Alexander Fleming in 1928 and developed for medical use in the 1940s, penicillin is a famous antibacterial agent. It is not an antifungal. D. Chloramphenicol (misspelled as Chloramfenical): This is a broad-spectrum antibacterial antibiotic, first isolated in 1947. It is not an antifungal. Therefore, Nystatin is recognized as one of the earliest effective antifungal agents
Cyano-bacteria are?
  • Gram positive
  • Gram negative
  • Both
  • None of all
The correct answer is B. Gram negative. Cyanobacteria (also known as blue-green algae, though they are prokaryotes and not true algae) possess a cell wall structure that is characteristic of Gram-negative bacteria. This means they have: An outer membrane. A relatively thin peptidoglycan layer between the outer membrane and the inner cytoplasmic membrane. Because of this cell wall structure, they do not retain the crystal violet stain during the Gram staining procedure and are instead counterstained (usually by safranin), appearing pink or red under a microscope.
The process of converting organic form of nitrogen into inorganic form of nitrogen is known as
  • Denitrification
  • Mineralization
  • Nitrification
  • Ammonification
The correct answer is Mineralization. Here's why: Mineralization: This is the general term for the decomposition of organic matter by microorganisms, which releases nutrients (like nitrogen, phosphorus, sulfur) from their organic forms into inorganic, plant-available forms. Specifically for nitrogen, organic nitrogen (e.g., in proteins, amino acids) is converted to inorganic ammonium (NH₄⁺). Let's look at the other options: Denitrification: This is the process where nitrate (NO₃⁻) or nitrite (NO₂⁻) (both inorganic forms) are converted back into gaseous nitrogen (N₂ or N₂O), which is lost to the atmosphere. So, it's inorganic to inorganic (gaseous). Nitrification: This is a two-step process where ammonium (NH₄⁺) (inorganic) is oxidized to nitrite (NO₂⁻) (inorganic), and then nitrite is oxidized to nitrate (NO₃⁻) (inorganic). So, it's inorganic to inorganic. Ammonification: This is the specific part of mineralization where organic nitrogen is converted into ammonium (NH₄⁺). While correct in that it produces an inorganic form from an organic one, mineralization is the broader, more encompassing term for the overall conversion of organic nutrients to inorganic forms. Ammonification is the first step in nitrogen mineralization. Therefore, Mineralization is the best and most general term for the conversion of organic nitrogen into inorganic nitrogen.
India's global position in cotton production is typically:
  • Second largest producer
  • Largest producer
  • Third largest producer
  • Largest exporter but not largest producer
Answer: b) Largest producer Explanation: India is generally recognized as the world's largest producer of cotton, surpassing countries like China and the USA in recent years.
Which of the following is a major destination for Indian cotton exports?
  • United States
  • Brazil
  • Bangladesh
  • Egypt
Answer: c) Bangladesh Explanation: Bangladesh, being a major apparel manufacturing hub with a large spinning industry but limited domestic cotton production, is a significant importer of Indian raw cotton. China and Vietnam are also key destinations.
A primary reason for India to sometimes import cotton, despite being a large producer, is
  • To meet demand for specific high-quality or Extra Long Staple (ELS) cotton
  • Insufficient domestic production to meet overall demand
  • Government policy to encourage imports
  • Lower international prices making imports cheaper than domestic cotton
To meet demand for specific high-quality or Extra Long Staple (ELS) cotton Explanation: While India is a large producer, there can be specific needs for certain qualities like ELS cotton (used for fine fabrics) which might not be sufficiently available domestically, leading to targeted imports.
What does "MSP operation" for cotton by CCI primarily aim to achieve?
  • Maximize profits for CCI
  • Ensure remunerative prices for cotton farmers and prevent distress sales
  • Control the retail price of cotton textiles
  • Boost cotton exports exclusively
Answer: b) Ensure remunerative prices for cotton farmers and prevent distress sales Explanation: MSP operations are a price support mechanism. When market prices fall below the MSP, CCI steps in to procure cotton at MSP, thus ensuring farmers get a minimum guaranteed price and are not forced into distress sales.
If the international price of cotton rises significantly while domestic prices remain stable, what is a likely impact on India's cotton trade?
  • India's cotton imports will increase
  • India's cotton exports will likely increase
  • Domestic consumption of cotton will decrease sharply
  • The MSP for cotton will be immediately reduced
Answer: b) India's cotton exports will likely increase Explanation: If international prices are high, Indian cotton becomes more competitive in the global market, making exports more attractive and profitable for Indian traders, assuming sufficient domestic availability.
Horse gram is a
  • Cereal crop
  • Aquatic weed
  • Erosion resisting crop
  • All of these
c) Erosion resisting crop Here's why: Horse gram (Macrotyloma uniflorum) is a legume. It's often grown as a cover crop, especially in dry and semi-arid regions. As a cover crop, its dense foliage and root system help to bind the soil, preventing soil erosion caused by wind and water. It is not a cereal (like wheat or rice), nor is it an aquatic weed. Therefore, the most fitting description among the options is an erosion resisting crop.
Natural air drying is recommended, if the RH is below
  • 100%
  • 70%
  • 60%
  • 80%
Natural air drying is recommended if the Relative Humidity (RH) is below 70%. Here's why: Relative Humidity and Drying: Natural air drying relies on the air's capacity to absorb moisture from the grain. If the RH of the ambient air is high, it means the air is already holding a lot of moisture and its capacity to pick up more moisture from the grain is limited. Equilibrium Moisture Content (EMC): Grain will dry until its moisture content reaches an equilibrium with the surrounding air's RH and temperature. If RH is too high (e.g., above 70-75%), the EMC of the grain will also be high, potentially not reaching safe storage levels and increasing the risk of mold growth and spoilage during the prolonged drying period. At an RH of around 70%, the EMC for many cereal grains is roughly 14-15%. For safe long-term storage, moisture content often needs to be below 13-14%. If RH is consistently below 70% (and ideally lower, e.g., 60% or less), the air has a greater drying potential, and the grain can dry down to safer moisture levels more effectively and quickly. Therefore, while lower RH is better, 70% is often cited as a general upper threshold above which natural air drying becomes inefficient, too slow, or risky. The correct answer is: (b) 70%
Specific gravity separator is used for grading the grain on the basis of
  • Same size but different specific gravity
  • Same size and same specific gravity
  • Different size but different specific gravity
  • Different size and same specific gravity
A specific gravity separator is used for grading grain on the basis of: (a) Same size but different specific gravity Explanation: Specific gravity separators (also known as density separators or gravity tables) work by differentiating materials based on their density (or specific gravity). While pre-cleaning for size is often done, the unique capability of this machine is to separate particles that might be of similar size but differ in their weight/density. For example, it can separate: Healthy, dense seeds from lighter, shriveled, diseased, or insect-damaged seeds of the same general size. Seeds from foreign materials (like small stones or dirt clods) that are of similar size but different density. The machine typically uses a combination of an inclined, vibrating, perforated deck and an upward airflow. Lighter particles are lifted more by the air and tend to move to one side (the lower side), while heavier particles remain in better contact with the vibrating deck and move to another side (the higher side).
Removal of silver skin and the bran layers of brown rice is called as
  • Hulling
  • Pearling
  • Polishing
  • Whitening
The removal of the silver skin and the bran layers of brown rice is most accurately called Polishing. Here's a breakdown: Hulling (or Dehusking): This is the first step, where the outermost inedible husk (hull or chaff) is removed from the paddy (rough rice) to produce brown rice. Brown rice still has the bran layers and germ intact. Pearling: This term is sometimes used, especially for barley, and can be applied to rice. It generally refers to the abrasive removal of the outer bran layers. It's a part of the process to get to white rice. Polishing: This is the process where the bran layers (including the aleurone layer or "silver skin") and the germ are rubbed off from brown rice to produce white rice. It makes the rice appear white and "polished." This is the most common and specific term for this stage. Whitening: This is a more general term that describes the overall effect of removing the colored bran layers, resulting in white rice. Polishing is the specific mechanical process that achieves whitening. While "pearling" describes an abrasive removal of outer layers, Polishing is the most common and precise term used in rice milling for the specific removal of the bran layers and silver skin from brown rice to produce white rice. Therefore, the best answer is: (c) Polishing
A significant challenge faced by the Indian cotton sector in the international market is often related to:
  • Extremely low production costs compared to competitors
  • Consistent oversupply leading to depressed global prices
  • Issues related to contamination and quality consistency
  • Lack of diversity in cotton varieties grown
Answer: (c) Issues related to contamination and quality consistency Explanation: While India is a major producer, issues related to contamination (e.g., with foreign matter, non-cotton fibers) and inconsistent quality (variations in fiber properties even within the same grade) have sometimes posed challenges for Indian cotton in the international market, affecting its price realization compared to cotton from countries with more stringent quality control. Efforts are continuously being made to address these issues. (a) Extremely low production costs: Production costs in India can be competitive but are not always "extremely low" when all factors are considered, and labor costs are rising. (b) Consistent oversupply leading to depressed global prices: While India is a large producer, global cotton prices are influenced by many factors including production in other major countries, global demand, and stock levels. India isn't solely responsible for consistent oversupply. (d) Lack of diversity in cotton varieties grown: India has a diverse range of cotton varieties, including different staple lengths.
In agriculture, wind energy is mainly used for
  • Water pumping
  • Harvesting
  • Fertilizer application
  • Sowing / planting
In agriculture, wind energy is mainly used for: (a) Water pumping Explanation: Water pumping: Historically, windmills were extensively used to pump water for livestock and irrigation. This is a direct mechanical application. Even with modern wind turbines generating electricity, one of the primary uses of that electricity on farms (especially in remote or off-grid locations, or where water needs are significant) can be for powering electric water pumps for irrigation or livestock. Let's look at why the other options are less common as a main use: Harvesting: Harvesting equipment (like combines) requires significant and consistent power, typically provided by internal combustion engines or, increasingly, large battery-electric systems. While wind could generate electricity to charge batteries, it's not a direct or primary energy source for the harvesting operation itself. Fertilizer application: Spreaders are usually tractor-powered. Again, wind-generated electricity could play an indirect role, but it's not the main direct use. Sowing / planting: Similar to harvesting and fertilizer application, planting equipment is typically powered by tractors. Therefore, water pumping remains the most prominent and direct application of wind energy in agricultural contexts, both historically and in many modern scenarios.
Seed drill is used for sowing
  • Small seeds
  • Bolder seeds
  • Seedlings
  • Plants
A seed drill is a device that sows seeds for crops by positioning them in the soil and burying them to a specific depth. While seed drills can be adapted for various seed sizes, the term is very commonly associated with sowing: (a) Small seeds Explanation: Small seeds: The term "seed drill" (or "grain drill") is very frequently used for machines that sow smaller-grained crops like wheat, barley, oats, rye, rice (direct-seeded), and various forage crops. These drills typically sow seeds in multiple rows with relatively close spacing. Bolder seeds: Machines used for larger ("bolder") seeds like corn, soybeans, cotton, or beans, which are often planted in wider rows with more precise individual seed placement, are frequently called planters or precision planters. While these are fundamentally a type of seed drill (they drill and place seeds), the terminology often distinguishes them. Seedlings: Seedlings are young plants that have already germinated. They are planted using a transplanter, not a seed drill. Plants: Similar to seedlings, more developed plants are also transplanted, not sown with a seed drill. Given the common agricultural terminology, while planters for bolder seeds are a form of seed drill, the term "seed drill" on its own often brings to mind the machines used for denser plantings of smaller-seeded crops. Therefore, (a) Small seeds is the most appropriate answer.
Which Indian state had the largest area under organic certification as per the provided data?

What is the minimum conversion period required before sowing for annual plant products to be certified organic, as per NSOP?
  • Twelve months
  • Two years
  • Three years (thirty-six months)
  • The certification agency decides on a case-by-case basis with no minimum.
Answer: (b) Two years Explanation: The section "Duration of Conversion Period" mentions, "Plant products produced can be certified organic when the national standards requirements have been met during a conversion period of at least two years before sowing.
Which of the following materials is prohibited for use as protected structure coverings or plastic mulches in organic farming according to the NSOP?
  • Polyethylene based products
  • Polypropylene based products
  • Polycarbonates
  • Polychloride based products
Answer: (d) Polychloride based products Explanation: In the section "Contamination control," it is mentioned, "For protected structure coverings, plastic mulches, fleeces, insect netting and silage rapping, only products based on polyethylene and polypropylene or other polycarbonates are allowed... The use of polychloride based products is prohibited."
The cauliflower mosaic virus particles contain
  • RNA
  • DNA
  • Both RNA and DNA
  • Either RNA or DNA
The Cauliflower Mosaic Virus (CaMV) particles contain DNA. Specifically, Cauliflower Mosaic Virus is a pararetrovirus that has a double-stranded DNA (dsDNA) genome. It is one of the few plant viruses with a DNA genome; most plant viruses have RNA genomes. So the answer is: (b) DNA
Mild mosaic in potato is caused by
  • Potato virus X
  • Potato virus Y
  • Both A and B
  • None of the above
Mild mosaic in potato is most commonly and characteristically caused by Potato virus X (PVX). Here's why: Potato virus X (PVX): This virus often causes mild mottling (light and dark green patches) on the leaves, or it can be latent, meaning the plant is infected but shows no visible symptoms. The term "mild mosaic" is very frequently associated with PVX infection. Potato virus Y (PVY): This virus can cause a variety of symptoms, including mosaic (which can range from mild to severe depending on the strain of PVY and potato variety), leaf drop streak, veinal necrosis, and stunting. While PVY can cause mosaic that might appear mild in some cases, it's also responsible for more severe symptoms. Both A and B: When PVX and PVY infect a potato plant together (co-infection), they often cause a more severe disease called "rugose mosaic," which is characterized by severe leaf distortion, crinkling, and stunting, and is definitely not "mild." Therefore, when referring specifically to "mild mosaic," Potato virus X is the primary causal agent. The answer is: (a) Potato virus X
Albugo candida causes white blisters or white rust of crucifers is a/an
  • Obligate parasite
  • Obligate saprophyte
  • Facultative parasite
  • Facultative saprophyte
Albugo candida, which causes white blisters or white rust of crucifers, is an Obligate parasite. Explanation: Obligate parasite: This means the organism can only survive and complete its life cycle on or within a living host. It cannot grow or reproduce on dead organic matter or artificial culture media. Albugo candida requires living crucifer tissue to obtain nutrients and reproduce. Let's look at the other terms: Obligate saprophyte: An organism that can only feed on dead organic matter. Facultative parasite: An organism that is primarily a saprophyte (feeds on dead matter) but can switch to become a parasite under certain conditions. Facultative saprophyte: An organism that is primarily a parasite (feeds on living matter) but can switch to become a saprophyte if its host dies or under certain conditions. Albugo candida is a biotroph, meaning it establishes a long-term feeding relationship with the living cells of its host without immediately killing them. This is characteristic of obligate parasites. Therefore, the correct answer is: (a) Obligate parasite

Read the given passage and answer the questions that follow. Comprehension: The internet, as we know it today, is the result of decades of technological innovation and development. Its origins can be traced back to the late 1960s in the United States, specifically to a project funded by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense. This project, known as ARPANET, was designed to create a decentralized computer network that could survive potential attacks and allow researchers to share information and resources. ARPANET was a groundbreaking concept, implementing packet switching technology, which breaks data into small packets that can travel independently across different routes and be reassembled at the destination. This was a significant departure from traditional circuit switching, which required a dedicated, continuous connection. Over the next couple of decades, ARPANET grew, connecting a limited number of universities and research institutions. Other networks also began to emerge, often funded by government agencies or large corporations. A pivotal moment in the internet's evolution came in the late 1980s and early 1990s. In 1989, Tim Berners-Lee, a scientist at CERN (the European Organization for Nuclear Research), invented the World Wide Web. While the internet is the underlying network infrastructure, the World Wide Web is a system of interconnected documents accessed via the internet, using protocols like HTTP (Hypertext Transfer Protocol) and HTML (Hypertext Markup Language). The invention of the Web, along with the development of user-friendly web browsers in the early 1990s, made the internet accessible to a much wider audience beyond academic and military circles. The commercialization of the internet and the proliferation of personal computers in the late 1990s and early 2000s led to its explosive growth. What began as a small, robust network for researchers transformed into a global phenomenon, connecting billions of people and revolutionizing communication, commerce, education, and entertainment. The internet continues to evolve, with ongoing developments in speed, accessibility, and new applications constantly reshaping our world. The origins of the internet, as described in the passage, can be traced back to a project funded by which U.S. agency?
  • FBI
  • CIA
  • NASA
  • ARPA
The first paragraph states, "...to a project funded by the Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense."

A man walks 5 km North, turns right and walks 10 km, then turns right and walks 5 km. In which direction is he now from his starting point?
  • North
  • South
  • East
  • West
1. Starts and walks 5 km North. (Current position relative to start: 5 km North) 2. Turns right (East) and walks 10 km. (Current position: 5 km North, 10 km East) 3. Turns right (South) and walks 5 km. (Current position: 5 km North - 5 km South = 0 km North/South relative to the Eastward line) He is now 10 km directly East from his starting point. So, he is in the East direction from the start.
Pointing to a photograph, a man said, "I have no brother or sister, but that man's father is my father's son." Whose photograph was it?
  • His own
  • His son's
  • His father's
  • His nephew's
The man has no brother or sister. "My father's son" can only be the man himself (since he has no other siblings). So, the statement simplifies to: "That man's father is me." If the man in the photograph's father is "me" (the speaker), then the man in the photograph must be the speaker's son.

  • Only II follows
Draw Venn Diagrams or use A-E-I-O rules: Statements: Some B are P (I type), All P are Pe (A type). From I + A: Some B are Pe (I type). Conclusion I matches this. (Some books are pencils). Conclusion II (No book is a pencil - E type) is contradictory to I and does not follow. Conclusion III (All pencils are pens - A type) is a converse of Statement 2 (All pens are pencils), which is "Some pencils are pens" (I type), not "All pencils are pens". So, III does not follow. Therefore, only Conclusion I follows.
Join our coaching class for guaranteed success in the exam." - An advertisement. Assumptions: I. Students want to succeed in the exam. II. Coaching classes can help students succeed in the exam.
  • Only assumption I is implicit
  • Only assumption II is implicit
  • Both assumptions I and II are implicit
  • Neither assumption I nor II is implicit
An advertisement for coaching implies certain assumptions: I. Students want success: The advertisement promises success to attract students. This wouldn't make sense if students didn't care about success. So, it is assumed students desire success. II. Coaching classes help success: The core premise of the advertisement is that joining the class will lead to success. This assumes that coaching classes have the ability to improve a student's chances of success. Both assumptions are necessary for the advertisement to be meaningful and persuasive.
Two positions of a single cube are shown below. Which face is opposite to the face with number 3? (Describe visible faces) Position 1: Faces 1, 2, 3 are visible. Position 2: Faces 2, 4, 5 are visible.
  • 1
  • 4
  • 5
  • 6
The common face in both positions is 2. If we move clockwise from 2 in Position 1, the faces are 2 -> 3 -> 1. If we move clockwise from 2 in Position 2, the faces are 2 -> 5 -> 4. Comparing the sequences, we find that the face opposite to 3 is 5, and the face opposite to 1 is 4. The remaining face, 6, must be opposite to the common face, 2. So, 3 is opposite 5.

Find the odd one out: Apple,Banana,Mango,Potato
  • Apple
  • Banana
  • Mango
  • Potato
The options list items. We need to find a property that most items share, but one does not. (A) Apple is a fruit. (B) Banana is a fruit. (C) Mango is a fruit. (D) Potato is a vegetable (specifically a tuber). Apple, Banana, and Mango are all botanically classified as fruits, whereas Potato is a vegetable. This is the most common distinction used in such reasoning questions. Another possible distinction could be how they grow: Apple and Mango grow on trees. Banana grows on a plant (often mistaken for a tree, but botanically a large herb). Potato grows underground as a root/tuber. Based on growing underground, Potato is the odd one out. Based on being a vegetable vs. fruit, Potato is the odd one out. Both classifications lead to Potato being the odd one out, making it the correct answer.
In a certain code language, if 'CUP' is coded as 40, what is the code for 'TOP'?
  • 48
  • 50
  • 51
  • 52
In this type of coding-decoding question, letters are usually assigned numerical values, often based on their position in the English alphabet (A=1, B=2, C=3, ..., Z=26). Let's find the numerical value for each letter in 'CUP': C is the 3rd letter. U is the 21st letter. P is the 16th letter. Now, let's see how these values might relate to the code 40: Sum of the values = 3 + 21 + 16 = 40. The code for 'CUP' is the sum of the alphabetical positions of its letters. Applying the same logic to 'TOP': T is the 20th letter. O is the 15th letter. P is the 16th letter. Sum of the values for 'TOP' = 20 + 15 + 16 = 51. So, the code for 'TOP' is 51.
An item was bought for ₹800 and sold for ₹1000. What is the profit percentage?
  • 20%
  • 25%
  • 30%
  • 15%
Cost Price (CP) = ₹800Selling Price (SP) = ₹1000Profit = SP - CP = ₹1000 - ₹800 = ₹200Profit Percentage = (Profit / CP) * 100Profit Percentage = (₹200 / ₹800) * 100 = (1/4) * 100 = 25%
The price of a commodity increased by 20%. If the new price is ₹600, what was the original price?
  • ₹480
  • ₹500
  • ₹540
  • ₹550
Let the original price be P.The price increased by 20%, so the new price is 100% + 20% = 120% of the original price.120% of P = ₹600(120/100) * P = 6001.2 * P = 600P = 600 / 1.2 = 6000 / 12 = ₹500Alternatively, 120% corresponds to ₹600. So, 10% corresponds to ₹600/12 = ₹50. The original price (100%) is 10 * ₹50 = ₹500.

Let the present age of Rohan be 3x years and the present age of Sohan be 4x years.The sum of their ages is 28 years.3x + 4x = 287x = 28x = 28 / 7 = 4Present age of Rohan = 3x = 3 * 4 = 12 years.Present age of Sohan = 4x = 4 * 4 = 16 years.
A can do a piece of work in 10 days, and B can do the same work in 15 days. If they work together, in how many days will the work be completed?
  • 5 days
  • 6 days
  • 7.5 days
  • 12.5 days
A's work rate per day = 1/10 of the work.B's work rate per day = 1/15 of the work.Combined work rate per day (A + B) = 1/10 + 1/15Find a common denominator (LCM of 10 and 15 is 30):Combined rate = (3/30) + (2/30) = 5/30 = 1/6 of the work per day.If they complete 1/6 of the work in 1 day, they will complete the whole work (1) in 6 days (1 / (1/6) = 6).
A car travels a distance of 180 km in 4 hours. At the same speed, how long will it take to travel 270 km?
  • 5 hours
  • 6 hours
  • 7 hours
  • 8 hours
First, calculate the speed of the car.Speed = Distance / Time = 180 km / 4 hours = 45 km/hour.Now, calculate the time needed to travel 270 km at this speed.Time = Distance / Speed = 270 km / 45 km/hour = 6 hours.

  • ₹1500
  • ₹1650
  • ₹1750
  • ₹2000
Simple Interest (SI) formula: SI = (Principal * Rate * Time) / 100Principal (P) = ₹5000Rate (R) = 10% per annumTime (T) = 3 yearsSI = (5000 * 10 * 3) / 100SI = (50000 * 3) / 100SI = 150000 / 100SI = ₹1500.
The average of 5 numbers is 30. If one number is removed, the average of the remaining numbers becomes 25. What is the number that was removed?
  • 40
  • 45
  • 50
  • 55
Sum of 5 numbers = Average * Number of items = 30 * 5 = 150.After removing one number, there are 4 numbers left.Sum of the remaining 4 numbers = New Average * Number of items = 25 * 4 = 100.The removed number is the difference between the sum of 5 numbers and the sum of 4 numbers.Removed number = 150 - 100 = 50.

  • 5/6
  • 10/3
  • 6
  • 20/3
Simplify the numerator first:1/2 + 1/3 = (3/6) + (2/6) = 5/6Now perform the division:(5/6) / (1/4) = (5/6) * (4/1)= (5 * 4) / (6 * 1) = 20 / 6Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (2):20 / 6 = 10 / 3.
The area of a rectangle is 120 sq cm. If its length is 15 cm, what is its perimeter?
  • 40 cm
  • 42 cm
  • 46 cm
  • 50 cm
Area of a rectangle = Length * Width120 sq cm = 15 cm * WidthWidth = 120 / 15 = 8 cm.Perimeter of a rectangle = 2 * (Length + Width)Perimeter = 2 * (15 cm + 8 cm) = 2 * (23 cm) = 46 cm.
The volume of a cube is 64 cubic cm. What is the length of its side?
  • 4 cm
  • 8 cm
  • 16 cm
  • 32 cm
The volume of a cube is given by the formula V = side³ (s³).Given Volume = 64 cubic cm.s³ = 64To find the side length 's', we need to find the cube root of 64.We know that 4 * 4 * 4 = 64.So, s = ³√64 = 4 cm.
The sum of two numbers is 45 and their difference is 9. What is the larger number?
  • 27
  • 18
  • 36
  • 21
Let the two numbers be x and y, where x is the larger number.Sum: x + y = 45 (Equation 1)Difference: x - y = 9 (Equation 2)Add Equation 1 and Equation 2:(x + y) + (x - y) = 45 + 92x = 54x = 54 / 2 = 27.The larger number is 27.(You can find the smaller number by substituting x=27 into Equation 1: 27 + y = 45 => y = 45 - 27 = 18. Check difference: 27 - 18 = 9, which is correct).
In a test, a student scored 80 marks in Math, 70 in Science, 60 in English, 50 in History, and 70 in Geography. What is the average marks scored by the student?
  • 60
  • 65
  • 66
  • 70
To find the average, sum all the marks and divide by the number of subjects.Subjects: Math, Science, English, History, Geography (5 subjects).Total Marks = 80 + 70 + 60 + 50 + 70 = 330.Average Marks = Total Marks / Number of Subjects = 330 / 5.330 / 5 = 66.
The production of three factories A, B, and C in a month were 500 tonnes, 750 tonnes, and 600 tonnes respectively. What is the ratio of the production of Factory A to Factory B?
  • 2:3
  • 3:2
  • 4:5
  • 5:4
Production of Factory A = 500 tonnes.Production of Factory B = 750 tonnes.The ratio of A to B is A : B.Ratio = 500 : 750To simplify the ratio, divide both numbers by their greatest common divisor (GCD). Both are divisible by 10 (50:75), then by 25.500 / 250 = 2750 / 250 = 3The simplified ratio is 2:3.
