Ans.(2). (a.) Bhopal; Explanation: Indian Institute of Soil Science is located at Bhopal, Madhya Pradesh. It works on soil health, soil fertility and sustainable soil management.

Ans.(3). (c.) Contingent cropping; Explanation: Contingent cropping means cultivation planned under adverse or abnormal weather conditions. It is used when normal cropping is affected by drought, flood, delayed monsoon or other aberrant conditions.

Ans.(4). (a.) Anemometer; Explanation: Wind speed is measured by an anemometer. It is an important meteorological instrument used in weather observation and agricultural planning.

Ans.(5). (c.) 15 ACZ; Explanation: India is divided into 15 agro-climatic zones. These zones are used for planning region-specific agriculture based on climate, soil, rainfall and cropping pattern.

Ans.(6). (b.) 5-6 cm; Explanation: According to the given answer key, shallow tillage depth is 5-6 cm. Shallow tillage disturbs only the upper soil layer and helps in weed control and moisture conservation.

Ans.(7). (a.) Drip irrigation; Explanation: Water loss in air is least in drip irrigation. Water is directly applied near the root zone, so evaporation and wind drift losses remain low.

Ans.(8). (d.) CRI; Explanation: CRI means Crown Root Initiation stage. It is the most critical irrigation stage in wheat when only one irrigation is available.

Ans.(9). (e.) None of the above; Explanation: Zero tillage means sowing crops without prior tillage or soil disturbance. It is not primary tillage, intercultural operation, weeding or summer ploughing.

Ans.(10). (b.) Moderately deep-rooted; Explanation: Soybean has a moderately deep-rooted system. Its roots help in nutrient absorption and nitrogen fixation through nodules.

Ans.(11). (b.) 200 per cent; Explanation: Wheat-paddy cropping system has 200 per cent cropping intensity because two crops are grown on the same land in one agricultural year.

Ans.(12). (d.) All of the above; Explanation: Water harvesting can be done by farm ponds, check dams and earthen dams. These structures store runoff water for irrigation and other farm uses.

Ans.(13). (e.) Drip irrigation; Explanation: Drip irrigation has minimum loss of water among the given methods. It reduces evaporation, runoff and deep percolation losses by applying water slowly near roots.

Ans.(14). (b.) 2000 ha; Explanation: A minor irrigation project has cultivable command area below 2000 ha. Such projects generally use local water resources like wells, tanks and small reservoirs.

Ans.(15). (d.) Conservative tillage; Explanation: Mulching is included under conservative tillage. It conserves soil moisture, reduces evaporation, suppresses weeds and protects soil from erosion.

Ans.(16). (c.) Agrostology; Explanation: Agrostology is the study of grasses. It includes grass classification, cultivation, forage grasses and pasture management.

Ans.(17). (c.) Nursery; Explanation: Dapog is a nursery method in rice cultivation. It is a mat nursery system used for raising young rice seedlings.

Ans.(19). (c.) 2 mm-0.2 mm; Explanation: Coarse sand particles range from 2 mm to 0.2 mm. Particle-size classification helps in identifying soil texture.

Ans.(20). (a.) Ultra-acidic soil; Explanation: Soil with pH less than 3.5 is called ultra-acidic soil. Such soils are highly acidic and generally unsuitable for most crops without reclamation.

Ans.(21). (a.) 0-20 per cent; Explanation: Sandy loam has about 0-20 per cent clay in the given answer key. It is light-textured soil with relatively good drainage.

Ans.(22). (d.) Extremely toxic; Explanation: Red label indicates extremely toxic material. Such products require careful handling, protective equipment and safe storage.

Ans.(23). (e.) Ca; Explanation: Calcium (Ca) is not a micronutrient; it is a secondary macronutrient. Mn, Cu, Zn and Mo are micronutrients required in small quantities.

Ans.(24). (a.) Splash erosion; Explanation: Splash erosion is the initial or minimum level of water erosion. It occurs when raindrop impact detaches and splashes soil particles.

Ans.(25). (c.) Gear pump; Explanation: A gear pump is used in high-pressure spraying systems. It helps generate pressure for spraying pesticides and other farm chemicals.

Ans.(26). (a.) Groundnut; Explanation: Leaf spot disease is commonly related to groundnut. It causes leaf lesions, defoliation and yield reduction if not controlled.

Ans.(27). (a.) NAFED; Explanation: NAFED is considered an apex organisation in agricultural cooperative marketing. It supports procurement, marketing and price stabilisation of agricultural commodities.

Ans.(28). (d.) NABARD; Explanation: Potential Linked Plan is prepared by NABARD. PLP estimates district-wise credit potential for agriculture and rural development activities.

Ans.(29). (b.) Bhadawari; Explanation: Bhadawari buffalo is known for high fat percentage in milk. It is an important Indian buffalo breed valued for rich milk.

Ans.(30). (b.) Buffalo; Explanation: The highest milk production in India comes from buffalo according to the given answer key. Buffalo milk also has comparatively higher fat content than cow milk.
