         Black soil is favorable for the cultivation of cotton.

         Because of this character of slow absorption and loss of moisture, the black soil retains the moisture for a very long time, which helps the crops, especially, the rain-fed ones, to sustain even during the dry season.

         Black Soil

o        These soils are also known as the ‘Regur Soil’ or the ‘Black Cotton Soil’.

o        The black soils are generally clayey, deep, and impermeable.

o        They swell and become sticky when wet and shrink when dried. 

o        So, during the dry season, this soil develops wide cracks. Thus, there occurs a kind of ‘self-plowing’.

o        The black soils are rich in lime, iron, magnesia, and alumina. They also contain potash.

o        They lack phosphorous, nitrogen, and organic matter.

o        The color of the soil ranges from deep black to grey.

o        Along with cotton, the soil is suitable for the cultivation of crops like groundnut, tobacco, chilies, and Jowar.

1.  Cultural controls: Practices that change the environment to make it less favorable for pests, such as crop rotation or sanitation.

2.  Biological controls: The use of natural enemies, such as predators and parasites, to control pests.

3.  Chemical controls: The use of pesticides to kill pests.

         Ethylene, also known as the "fruit-ripening hormone," is a gas. Throughout its lifecycle, every fruit produces a certain amount of ethylene.

         When fruit begins to ripen, however, ethylene levels rise dramatically.

         Fruits can be divided into two classes based on how they react to ethylene during maturation.

         The climacteric fruits are the first category, with ripening followed by an ethylene explosion.

         The non-climacteric fruits are those whose ethylene production does not increase as the fruit ripens.

         Auxins encourage stem elongation while inhibiting lateral bud development (maintains apical dominance). The stem, buds, and root tips all contain them.

         Helicoverpa armigera is a polyphagous pest, meaning it can eat a wide variety of plants.

         It is an important pest of many crops, including cotton, soybean, and vegetables. However, it is particularly damaging to gram/bengal gram.

         The larvae of H. armigera can damage gram/bengal gram by feeding on the leaves, flowers, and pods.

         This can lead to yield losses of up to 80%.

2.  Explanation:

         In the rainfall reaching the surface of a catchment the major abstraction is through infiltration process. However, two other processes, though small in magnitude, reduce the water volume available for runoff and thus act as abstractions. These are the interception process and the depression storage, and together they are called initial loss.

         The process of water entering the soil surface is known as infiltration.

         The downward entry of water into the immediate surface of soil or other materials is called infiltration process.

         Water through irrigation/rainfall infiltrates into the soil surface and is stored for use by plants.

         Evaporation is the primary process of water transfer in the hydrological cycle.

         It is the physical process of vaporization by which liquid is transformed to a gaseous stage from its free surface through the absorption of heat energy.

         A part of precipitation is intercepted by the vegetation and subsequently evaporated before it reaches the ground.

         The precipitation may be intercepted in one of the following ways:

o        ​The intercepted water retained on the vegetation as surface storage and evaporated to the atmosphere;

o        Water falling from the plant leaf; and

o        The rainwater splashing through leaves, branches, stem and reaching the ground surface known as stem flow.

         Evapotranspiration also known as consumptive use is the sum of evaporation from cropped and fallow area, water surfaces, plant leaves and transpiration through the plant leaves into atmosphere.

         Water falling on plant system through rainfall, dew, sprinkler method of irrigation and evaporating is also a part of consumptive use.

         The estimation of evapotranspiration is crucial for a command area/watershed as it is one of most important components of water balance equation used for water budgeting.

         For the regular and all-round development of agricultural production, on the basis of the recommendation of the National Agriculture Commission, a provision has been made for the formation of Madhya Pradesh State Agricultural Marketing Board in the year 1973 in the Mandi Act.

o        Mandi Board has seven regional offices in Madhya Pradesh.

o        These offices are at Bhopal, Indore, Ujjain, Gwalior, Sagar, Jabalpur and Rewa.

o        The State Government of Madhya Pradesh established the Mandi Board to keep the interests of the productive farmers paramount in the marketing of agricultural products.

1.   Madhya Pradesh is known as the Soybean State of India and ranks first in the country in the production of soybean.

2.  The state has earned the highest award "Krishi Karman" given by the Government of India in the field of agriculture for six consecutive years.

3.  Madhya Pradesh also ranks first in the country in the production of Gram, Urad, Tur, Masoor, and Linseed.

         The study of agronomy dealing with the relationship of yield to the quantity of an added or available fertilizer element is called Agrobiology.

         Agrobiology is a branch of agricultural science that focuses on understanding the biological principles and processes related to agriculture.

         It involves the study of plant and animal sciences, soil science, ecology, and agricultural practices to optimize crop production and yield.

         In the context of the given question, Agrobiology examines the impact of fertilizer elements on yield and explores the relationship between nutrient availability in the soil and plant growth.

         Soil fertility is also a relevant concept in agronomy, but it refers more broadly to the nutrient content and availability in the soil rather than specifically focusing on the relationship between yield and fertilizer elements.

         Agrology primarily deals with soil properties, formation, classification, and mapping rather than the specific relationship between yield and fertilizer elements.

         Soil productivity is a related concept that refers to the ability of soil to support plant growth and produce agricultural crops efficiently, but it does not directly address the relationship with added or available fertilizer elements.

         Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya (RVSKVV) is situated in Gwalior, Madhya Pradesh.

         RVSKVV is an agricultural university that focuses on education, research, and extension activities in the field of agriculture and allied sciences.

         The university offers undergraduate, postgraduate, and doctoral programs in various disciplines related to agriculture, horticulture, and agricultural engineering.

         RVSKVV aims to contribute to the development of agriculture in Madhya Pradesh and the surrounding regions through quality education, research innovations, and technology transfer.

         When a plant part undergoes senescence, which is the natural process of aging and deterioration, the nutrients present in that part are typically translocated or moved to other parts of the plant.

         Senescence often occurs in older leaves or reproductive structures, where the plant reallocates resources to other active parts.

         Nutrients, such as nitrogen, phosphorus, potassium, and other essential elements, can be mobilized from senescent tissues and transported to other actively growing parts, such as younger leaves, developing fruits, or storage organs.

         This nutrient translocation allows the plant to prioritize resources and maximize the utilization of nutrients for vital physiological processes and growth in actively growing tissues.

         Essential nutrients are necessary for the plant to complete its life cycle.

         They include both macro-nutrients and micro-nutrients.

         Macro-nutrients are required in larger quantities, while micro-nutrients are needed in smaller amounts.

         Macro-nutrients include elements like nitrogen, phosphorus, and potassium.

         Micro-nutrients include elements like iron, zinc, and copper.

         Plants require a balanced supply of essential nutrients for healthy growth and reproduction.

         Lack or deficiency of any essential nutrient can result in stunted growth, nutrient deficiencies, and overall poor plant health.

         It is important for gardeners and farmers to provide plants with the necessary essential nutrients through proper soil fertilization and nutrient management practices.

         The specific nutrient requirements can vary among different plant species and may also depend on factors like soil type, pH, and environmental conditions.

         In India, the Indian Council of Agricultural Research (ICAR) has classified soils into 8 categories.

         Alluvial Soil, Black Cotton Soil, Red Soil, Laterite Soil, Mountainous or Forest Soils, Arid or Desert Soil, Saline and Alkaline Soil, Peaty, and Marshy Soil are the categories of Indian Soil.

         Alluvial soil is formed by the deposition of silt by the Indo-Gangetic-Brahmaputra rivers.

         This soil group covers around 46% of the total land area.

         It supports nearly half of the Indian population by providing the most productive agricultural lands.

         It contains an adequate amount of potash, alkalies and phosphoric acid.

         The soil is most suitable for crops such as rice, sugarcane, wheat, tobacco, maize, fruits, vegetables and jute. 

         Red Soil is soil developed on Archean granite that occupies the second largest area of the country.

o        They are mainly found in the Peninsula from Tamil Nadu in the south to Bundelkhand in the north and Raj Mahal in the east to Kathiawad in the west. 

         Black soil is also known as cotton soil and internationally it is known as ‘Tropical Chernozems’.

o        This is the third largest group in India.

o        This soil is formed from rocks of cretaceous lava.

o        This stretch over the parts of Gujarat, Maharashtra, Western parts of Madhya Pradesh, North- Western Andhra Pradesh, Karnataka, Tamil Nadu, Rajasthan, Chhattisgarh, Jharkhand up to Raj Mahal hills. 

         Desert soil is deposited by wind action and mainly found in the arid and semi-arid areas like Rajasthan, West of the Aravallis, Northern Gujarat, Saurashtra, Kachchh, Western parts of Haryana and southern part of Punjab.

o        They are sandy with low organic matter.

o        It has low soluble salts and moisture with very low retaining capacity.

o        If irrigated this soil gives a high agricultural return.

         The ‘Grow More Food’ campaign was launched in the year 1948. 

         Partition of India in 1947 had caused imbalances in the agricultural sector in India.

         As a result, the “Grow-more-food” campaign was therefore placed on a planned basis from 1947-48.

         This campaign was launched in 1948 as a programme of crop production.

o        It included field demonstration and contacting with the farmers to introduce the improved techniques

o        It initiated a dialogue with the villagers.

         It is pertinent to note that the campaign failed to achieve its targets.

         The Government re-defined the objectives of the Grow-More-Food Campaign as the attainment of self-sufficiency in food grains by 1952.

o        It simultaneously increased the targets of production of other crops to meet the shortfall as a result of the partition of the country.

         Green GDP -  is defined as data obtained after the deduction of the cost of resources, environment, and human health from the traditional GDP.

         In 2006, the Chinese government released its Green GDP for Yangshan Deep-water Port.

         Development of Green GDP :

o        The way to calculate GDP has not included the utilization of natural resources, so it can not reflect the economic loss of natural resources.

o        That means to take air, water, and forests as an example, everyone can get as much as these natural resources at free, these natural resources loss is not included in the field of calculating GDP. 

o        So GDP can not reflect the economic loss of natural resources, and also can not restrict the uses of natural resources by people efficiently and effectively.

o        Furthermore, it can lead to severe environmental pollution and the losing of valuable natural resources. As a solution to meet the requirement of sustainable development, it comes out the point of adding environmental factors into the accounting method of GDP
and the concept of “environmental cost”, which then developed into green GDP theory. 

         From the production view, green GDP is the total national income value deduct natural resource and environmental costs. 

         The natural resources are divided into two categories,

o        The loss of natural resources, it means the consumption of natural resource which is directly used in the production process,

o        The degradation of the environment means the environment grade has greatly reduced due to the overuse of the environment. 

         Green GDP = GDP - R - A

o        R = Expenditure required to restore environmental capital.

o        A = Expenditure to avert the destruction of environmental capital.

         Chlorosis is the loss of the normal green coloration of leaves of plants due to loss of chlorophyll.

         It leads to yellowing of leaves.

         This is caused by iron deficiency in lime-rich soils, or due to diseases, or lack of light.

         Other elements that cause chlorosis are nitrogen, potassium, magnesium, sulphur, manganese, zinc, etc.

         Turning and loosening of soil are important steps in proper land preparation for better crop production.

         Turning refers to the process of flipping the top layer of soil, bringing the lower layers to the surface, which helps to mix and incorporate organic matter and nutrients.

         Budding is a form of asexual or vegetative propagation that involves joining a bud from one plant onto the stem of another plant, known as the rootstock.

         In rose propagation through budding, a bud from the desired rose variety, known as the scion, is inserted into a slit or cut made on the rootstock.

         The bud is then secured in place using grafting tape or similar materials, allowing it to grow and eventually form a new rose plant.

         Budding is preferred for roses due to its efficiency, reliability, and the ability to reproduce true-to-type plants with the same characteristics as the parent variety

         The biological method involves the use of living organisms to control pest populations.

         Biological control is a pest management strategy that utilizes natural enemies, such as predators, parasites, pathogens, or beneficial insects, to regulate or suppress pest populations.

         The purpose of biological control is to establish a balance between pests and their natural enemies, reducing the need for chemical pesticides.

         Biological control agents can target various pest species, including insects, mites, weeds, and plant diseases.

         Examples of biological control agents include ladybugs, lacewings, predatory mites, nematodes, parasitic wasps, and certain fungi or bacteria.

         These organisms can directly attack pests, feed on them, parasitize them, or infect them with diseases, helping to reduce pest populations and mitigate crop damage.

         Soil biomass is comprised of all living organisms and materials that have arisen from their decomposition.

         It is divided into live (micro-and macroscopic organisms, plant roots, and subsurface stems) and residual biomass (organic matter from decomposing plants and animals).

         The microbial biomass typically makes up less than 5 % of total soil organic matter, but it plays a very large role in several key soil functions, including nutrient release, the maintenance of good soil structure, and the suppression of plant pathogens.
