Question

Rohan grew berseem and cowpea in his field When the plants were about one foot high he ploughed them back into soil What is the most appropriate reason for this ?

• A. The crop has caught some disease
• B. Extensive growth of berseem has affected growth of cowpea plants
• C. It helps in nutrient enrichment of soil
• D. None of these

Answer 1

The correct option is C It helps in nutrient enrichment of soil

Some cover crops are legumes that add nitrogen to the soil. Cowpea cover crops are cost-effective because they enrich the soil with organic matter, add over 100 lbs per acre of nitrogen, and have other harder to define benefits for crops grown in rotation with them.
