Question

Green manuring enhances crop yield by

• A. 5 - 10%
• B. 15 - 25%
• C. 30 - 50%
• D. 60 - 70%

Answer 1

Answer: (C)

30 - 50%

Green manuring is the practice of growing a short duration, succulent and leafy legume crop and ploughing the plants in the same field before they form seeds. It provides nitrogen or substitute for nitrogen fertilizers. Slowly decomposing green matter increases the soil organic resources and provides residual effects to future crops. Green manuring increases the yield of crop by 30-50%. Breaking and rotation of crops in the same field helps to improve the yield.

Thus, the correct answer is option C.
