Crotalaria Juncea Fruits
The Crotalaria juncea, also known as Indian hemp, brown hemp, Madras-hemp, and Bengal hemp, is an annual plant native to India. It is currently displaying a terminal open raceme up to 25 cm long with showy, deep-yellow papillonaceous flowers. The plant is growing to a height of 3-9 ft and has a lengthy tap root with vigorous lateral roots. The fruit of the Crotalaria juncea, or sunn hemp, is a cylindrical, hairy pod containing many seeds and turns light brown when mature. It measures about 3-6 cm long and 1-2 cm in diameter. The fruit is also called a 'rattlepod' because of the clustered seeds in the pod. The Crotalaria juncea is being used as a cover crop to improve soil properties, reduce soil erosion, conserve soil water, and recycle plant nutrients. When grown as a summer annual, it is producing over 5,000 pounds of biomass and 100 pounds of nitrogen per acre. The plant has many practical applications, including as a source of natural fiber for cordage, fishing nets, ropes, and more, and is beneficial for its resistance to root-knot nematodes and its ability to improve soil through nitrogen fixation. The Crotalaria juncea also has a relatively high fuel value, and research is ongoing to optimize the extraction of oil from it to utilize this fuel value. A branch of the Crotalaria juncea with fruits is being observed in Tehatta, West Bengal, India, on March 31, 2024. (Photo by Soumyabrata Roy/NurPhoto)
