Description 
Branched erect annual 2-3 m high with elliptical lanceolate leaves and yellow terminal flowers. The pods are small and inflated, having stiff hairs. Yield of herbage can be high, especially when fertilized with phosphorus.
Nutritional aspects
Potential constraints 
The seeds and pods are sometimes toxic and should therefore be removed before feeding.
Ruminants 
Commonly grown in India for fodder. Can be used as fresh forage or made into hay. In Andhra Pradesh (India) it is stacked in alternate layers with rice straw to increase the value of the straw. Young plants are not palatable.
