Any plant's leaves can be used for formation of green manure. Some crops are grown so that they can be ploughed back into the soil. Some examples are berseem, kulthi, sunhemp, lobia, green gram, etc. These plants are ploughed and mixed into the soil and then allowed to decompose. After decomposition, it becomes green manure.
