Solution(By Examveda Team)

Green manure is a crop specifically produced to be incorporated into the soil while still green. The primary goal is to add organic matter to the soil for its benefits and the most likely used crops are legumes which add nitrogen to the soil. Aeschynomene afraspera is an annual to perennial plant that can grow 1 - 3 meters tall with stems that can become somewhat woody and persist.
