Sunn Hemp Crotalaria juncea

Sunn hemp is a fast-growing tropical legume that can produce over 2.5 tons of dry matter per acre in within 90-120 days. A multipurpose crop, sunn hemp can be used for forage, cover crop, and wildlife. It is best planted on well-drained soils.  

Cover Crop

When used as a summer cover crop, sunn hemp may contribute 100-120 lbs/acre of nitrogen in the summer and fall. Easily killed by a hard winter freeze, it is ideal for use where natural winter kill is desired.

Wildlife

For use in a wildlife plot, sunn hemp provides all the soil benefits of cover crops as well as a source for summer and fall feed.
