However, the strict control of cannabis cultivation to combat illegal use, the spread of new yarns and oilseeds, and the advent of cheap synthetic fibers caused a decreased/eliminated hemp production
Hemp has a long history of being used for fiber, grain, and medicinal purposes, but its cultivation has been strictly controlled due to concerns about illegal drug use, competition from synthetic fibers, and bans in many countries.
However, with the legalization of hemp in the USA through the 2014 and 2018 Farm Bill, research programs have been launched by universities to explore its potential. Hemp has the advantage of being a versatile crop that can be used for multiple purposes, creating opportunities for the market to value hemp products.
This paper, published on MDPI Open Access Jurnals, highlights that hemp has the potential to be a sustainable and environmentally friendly crop, with its ability to absorb heavy metals, sequester carbon, and suppress weeds without the use of pesticides. The paper aims to examine the historical and recent literature on hemp agronomy and utilization, focusing on industrial hemp for grain and fiber production.
