Skinner, E. M., Díaz-Pérez, J. C., Phatak, S. C., Schomberg, H. H., & Vencill, W. (2012). Four different genotypes of Crotalaria juncea were observed for three years to determine which genotype would yield in a high fibre yield. Out of the four genotypes, namely SUIN-029, SUIN-080, SUIN-037, and SUIN-043, SUIN-029 was superior in resulting in a high fibre yield. The seed will germinate at soil temp of 48°F However, the plant grows much better as the soil temperatures and night temperatures are much warmer. It is generally considered to have originated in India. More specifically, the vegetable seedling production of lettuce, beetroot, and tomatoes was measured by observing the shoot height, fresh mass production in shoots and dry matter, and leaf number. https://web.archive.org/web/20110721163337/http://assamagribusiness.nic.in/Sunnhemp.pdf, http://www.fao.org/ag/AGP/AGPC/doc/GBASE/data/pf000475.htm, Crotalaria Juncea - Sunn Hemp - Grass Seed (PDF papers), Crotalaria Juncea - Sunn Hemp - Basic Information Paper, https://en.wikipedia.org/w/index.php?title=Crotalaria_juncea&oldid=976730158, Articles needing additional references from January 2017, All articles needing additional references, Wikipedia articles incorporating a citation from the New International Encyclopedia, Creative Commons Attribution-ShareAlike License, This page was last edited on 4 September 2020, at 17:10. 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. The fibre is obtained from the plant by retting in a similar way to flax. Sunn is likely native to the Indian subcontinent, where it has been cultivated since prehistoric times. Sunn Hemp should not be confused with the Industrial Hemp Crop that the University of Florida is currently researching.

Anytime after the last frost will work but … [8] Crotalaria juncea, reduced both the germination and seedlings of various crop species (bell pepper, tomato, onion, and others). However, a novel three-phase partitioning based extraction shows an oil yield of 37% in two hours at 37 degrees Celsius. The quality of hemp fibre depends greatly on whether the crop was grown primarily for textiles, or is dual-purpose. It has regained interest in the late 2000s as its fibre is reported to be more environmentally friendly than synthetic fibres, and having valuable traits for paper industries. Stem is up to 2 cm in diameter, cylindrical and ribbed with short appressed hairs. Base: 100% Polyester . Despite the high levels of copper in the soil of Crotalaria juncea, mechanisms have been determined which can reverse the toxic effects of copper and allow for growth of the plant. The bast fibre of a plant (Crotalaria Juncea) which is largely used for cord and rope making. 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. Leaf simple, c. 2.5v10.5 cm long, c. 6–20 mm broad, linear or oblong, obtuse or subacute, apiculate, pubescent on both sides, hairs appressed, silky. Evaluation of sunnhemp (Crotalaria juncea) genotypes for high fibre yield. [17] Phosphate uptake is significantly improved in the presence of AMF, which functions to effectively reduce the amount of available heavy metals. Dutta, R., Sarkar, U., & Mukherjee, A.

It is of better quality than jute, lighter in colour and greater strength and… Sunn hemp, like hemp (Cannabis sativa), is mainly grown as a fibre crop that was much used in the traditional manufacture of ropes, strings, twines, floor mats, and fishing nets. According to the USDA NRCS Plant Guide, sunn hemp originated in India where it has been grown since the dawn of agriculture. Sunn Hemp Shows Promise as Biofuel Source. Sunn hemp originated in India where it has been grown since the dawn of agriculture. [10] The compost with 66% Crotalaria juncea and 33% Napier grass was superior to other combinations since this particular combination yielded the greatest production of lettuce, beet, and tomato seedlings. Bark yields fiber used in making twine and cord, canvas and fishing nets, and paper and pulp. We have found that it is an acquired taste but high in crude protein (CP) and total digestible nutrients (TDN). The study of these properties is vital for comparison with similar properties of synthetic fibres and for assessing hemp fibres’ suitability for use as reinforcement in composite materials. [10] The objective was to find the mixture between Crotalaria juncea and Napier grass that would yield the highest vegetable seedling production. Phytoremediation has been demonstrated to be effective as for correcting Crotalaria juncea found in soils contaminated with herbicides. Cornejo, Pablo, Sebastián Meier, Gilda Borie, Matthias C. Rillig, and Fernando Borie (2008) Glomalin-related Soil Protein in a Mediterranean Ecosystem Affected by a copper Smelter and Its Contribution to Cu and Zn Sequestration. Varieties of hemp, whose stems are used for fiber, bio-fuel, or other products, grow to 6-7 feet in height, providing the desired long fibers for industrial processing. The term “Hemp” is often incorrectly used in a generic sense for fibers from different plants eg; Manila “Hemp”, Sisal “Hemp”, Sunn “Hemp” etc. Start grazing when plants are one and a half to three feet tall, approximately 45 days after planting. Care Instructions: Wash Cold. Engineered With fusion / TECHNOLOGY. Sunn Hemp is called this because of its bright yellow flowers and that it can be a source of fibre (hemp). Another effective approach in decreasing the levels of copper in Crotalaria juncea is with the use of arbuscular mycorrhizal fungi (AMF). Utilization of organic compost as substrate for vegetable seedling production. No Iron. Sunn hemp is originally from India and has been grown since the dawn of agriculture. Bragantia. It also grows well on clay soils and will tolerate low fertility providing that soils are well-drained.
