Which one of the following pulse crops is used as a pulse, a fodder and a green manure crop

Answer: Option C

Cowpea is the pulse crop that is used as a pulse, fodder, and green manure crop. It is an annual herbaceous legume and an important crop in the semi-arid regions as it can tolerate sandy soil and low rainfall.
It requires very few resources, as the plant's root nodules can fix atmospheric nitrogen.
