Crotalaria juncea ‘CIAT’ sunn hemp is a vigorous tropical annual legume grown as a warm-season cover crop for rapid biomass, soil protection, and nitrogen fixation. Its upright growth and deep taproot perform especially well during the hottest part of summer, and plants may begin flowering about 60–75 days after planting when conditions are favorable.Sow after frost danger has passed into warm soil—approximately 65°F or warmer—and choose a well-drained site. Sunn hemp tolerates relatively low fertility and acidic soil, but it does not tolerate saturated conditions. For a cover-crop stand, drill or broadcast seed evenly and avoid overly wide rows that leave soil exposed. Terminate before mature seed develops and before stems become excessively fibrous if easy incorporation is the goal. Application rate: 15–30 lb per acre Inoculant: This is raw, uncoated seed. Inoculate before planting with Cowpea, Peanut & Lespedeza Inoculant to support effective nodulation and nitrogen fixation. Germination: Approximately 5–10 days in warm, moist soil Plant height: Approximately 5–6 feet Primary uses: Biomass, green manure, soil cover, summer weed competition, and crop rotation Additional notes: Heat loving; damaged by frost; reported resistance to some root-knot and reniform nematodes can vary with pest population and growing conditions. Minimum order quantity is 50 pounds.
