Sunn hemp is a rapid growing crop that is used for fiber production in Indo-Pakistan. It is also good for use as a green manure in many tropical and subtropical areas in the world as an organic and nitrogen source. It suppresses weeds, slows soil erosion, and reduces root-knot nematode populations. When plowed under at early bloom stage, nitrogen recovery is the highest. Branched erect annual 2-3 m high with elliptical lanceolate leaves and yellow terminal flowers. The pods are small and inflated, having stiff hairs. Commonly grown in India for fodder. The seeds and pods are sometimes toxic and should therefore be removed before feeding.
