Crops & Top Producing States — Set 11

Correct Answer: D. All of the above

The correct answer is 'All of the above'. All pulses, including chickpea, lentil, and black gram, are excellent sources of iron. They provide bioavailable iron essential for preventing anemia and supporting overall health. Consuming pulses regularly is important for nutrition.

Correct Answer: B. Provide nutrients gradually and reduce leaching

The correct answer is Provide nutrients gradually and reduce leaching. Controlled-release fertilizers release nutrients gradually matching crop requirements, reducing nutrient leaching and environmental pollution. They improve nutrient use efficiency and provide sustained plant nutrition. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. Chickpea (Chana)

The correct answer is Chickpea (Chana). Chickpea (Chana) is primarily a Rabi season crop grown from October to March. It is the largest pulses crop in India by production volume, widely grown in central and northern regions. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. Improve water conservation and increase agricultural productivity

The correct answer is Improve water conservation and increase agricultural productivity. Watershed management conserves water through contour bunding, recharge pits, and storage structures. It improves water availability for agriculture, supports rainfed farming, and enhances groundwater levels. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: C. Black soil

The correct answer is Black soil. Black soil (regur) is most suitable for cotton cultivation due to its high water-holding capacity and fertility. These soils are found in the Deccan region, providing ideal conditions for cotton growth and productivity. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. Improve soil structure and nutrient availability

The correct answer is Improve soil structure and nutrient availability. Deep plowing breaks compact layers, improves soil aeration, enhances microbial activity, and increases nutrient availability. It prepares the soil well for crop cultivation and improves overall soil health. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: C. Zinc

The correct answer is Zinc. Zinc is an essential micronutrient for crop growth, involved in enzyme function and protein synthesis. Zinc deficiency is common in Indian soils and significantly affects crop productivity across various crops. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. Enrich soil with nitrogen and improve sustainability

The correct answer is Enrich soil with nitrogen and improve sustainability. Legume crops fix atmospheric nitrogen through symbiotic bacteria, enriching soil naturally. They reduce chemical fertilizer dependence, improve soil health, and support sustainable agricultural practices. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. Soybean

The correct answer is Soybean. Soybean is primarily cultivated in the Kharif season in India, particularly in Madhya Pradesh and Rajasthan. It is an important source of vegetable protein and oil, widely used in food and animal feed production. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.

Correct Answer: B. Store water for irrigation and recharge groundwater

The correct answer is Store water for irrigation and recharge groundwater. Farm ponds store seasonal rainwater for agricultural use during dry periods. They support irrigation, recharge groundwater, reduce dependency on surface water, and improve water availability for farming. This topic is frequently tested in competitive examinations such as RRB NTPC, SSC, and UPSC.
