Sunhemp / Sunn hemp - Crotalaria Juncea - Green Manure

Seeds for Africa




Sunn hemp, Crotalaria juncea L. is popular as a green manure in many tropical and subtropical areas in the world as an organic nitrogen source. Sunn hemp suppresses weeds, slows soil erosion, and reduces root-knot nematode populations. When ploughed under at early bloom stage, nitrogen recovery is the highest. Under optimum growing conditions sunn hemp can produce 134 to 147 lb/acre of nitrogen (N) and 3 tons/acre air-dry organic matter at 60 days of growth at 40 kg seed/ha. We recommend planting sun hemp at 100gms of seed to 25m2.
