Sunn Hemp is an erect, herbaceous annual shrub. It is a summer legume crop with a well- developed taproot system. It is primarily used as a cover crop or as green manuring to improve the nitrogen status of the soil. It can also be used as a source of fibre, but has limited use as a forage crop.
This is mostly due to the palatability, digestibility and alkaloid toxicity of the crop. It requires a minimum rainfall of 300 mm per annum.
