Plant height and above-ground biomass were recorded at 30, 60, and 90 days after planting (DAP). Sunn Hemp Seed (Crotolaria Juncea) - Sunn Hemp is a fast growing nitrogen fixing legume. At first, livestock may not find sunn hemp palatable, but within one to three days, they will develop a “taste” for sunn hemp. In many countries it is the number one cover crop for reclaiming poor land. Sunn Hemp is a tropical legume that is capable of producing 120 lbs. As a warm season cover crop legume, Sunn Hemp increases soil organic matter, provides nitrogen, grows in low fertility sandy soils, and does not harbor most types of nematodes most destructive to crops in North America, generally found in sandy soils in Southern growing regions. The advantages of using sunn hemp as a cover crop are the large amount of biomass produced per acre, nitrogen fixation, nematode suppression, and weed suppression. Modular Chicken Coop Poultry and Hen House with Solid Top Shaded Run/Yard (5) Sunn Hemp is a tropical legume. Seed pods require longer to dry than stems and might delay curing slightly longer than plant material without seed pods. Seeding Rate: Our recommended seeding rate is 15 lbs.

The concept may be worth considering for dairy farmers in warmer growing zones. Anytime after the last frost will work but waiting for warmer temperatures makes the plant grow much better. It can reach plant heights of 6- 7 feet tall. Its greater CP concentrations make it beneficial for livestock growth in the summer and its high level of biological N 2 fixation makes it a good companion plant for the warm-season perennial grasses. Sunn Hemp nodulates readily with native cowpea-type rhizobia inoculant. When sunn hemp is at 80 percent bloom, only 35 to 40 percent of the field biomass is leaves. Sunn Hemp is used for green manure forage, organic soil building and cover crop applications. Global Sunn requires eight weeks in warm conditions to provide maximum benefit.
