This guide will walk you through how to use sunn hemp to increase your crops and provide feed for livestock and wildlife. Sunn hemp (Crotalaria juncea). It is particularly beneficial because of its resistance to root-knot nematodes and is also a soil improving crop via nitrogen fixation. [7], Furthermore, Crotalaria juncea has applications in the agricultural field since it impacts common food production. [2], It is now widely grown throughout the tropics and subtropics[2] as a source of green manure, fodder and lignified fiber obtained from its stem. When the application of phosphate is coupled with the inoculation of Rhizophagus clarus, the result is a synergistic effect that allows copper toxicity levels to be reduced through various mechanisms. Varieties such as Futura 75, Futura 77, and Fanola have had some validation for Nebraska conditions. The properties of hemp fibres were found to be good enough to be used as reinforcement in composite materials. The leaves are of high quality (see Table 1), but the stems are of much lower quality (8-10% crude protein, 75% neutral detergent fiber, 65% acid detergent fiber). The species name juncea was given to this plant by Linnaeus because of its resemblance to Spartium junceaum L., the Spanish broom of the Mediterranean region with its green rush like, scantily-leaved branches. No Bleach.
