Researchers determine optimal growing conditions for industrial hemp in North Carolina
Industrial hemp is currently used in a variety of products around the world. Hemp is a multipurpose crop delivering seeds, fibers and bio-active chemicals that has the potential for a number of uses and markets. One of the important products of industrial hemp is medicinal cannabinoid (CBD). Studies have shown that CBD safely and effectively reduces nausea and vomiting and has potential as a treatment option for neuro-inflammation disorders, epilepsy, oxidative injury, anxiety and schizophrenia. Growing hemp in North Carolina was legalized in 2016, and there are now 1,500 licensed growers cultivating more than 17,000 acres.
North Carolina A&T State University researchers have demonstrated that higher fertilizer rates increased yields and the CBD level in industrial hemp grown in North Carolina. This project has identified the optimum fertilizer rates to maximize CBD production in two hemp varieties – Spectrum and Therapy – while keeping the THC concentration within the legal limit. This research makes an important contribution to the development of best management practices for growers of industrial hemp for CBD.
