Hemp is a non-psychoactive variety of cannabis sativa L. Hemp is a crop of historical importance in the U.S. and re-emerging worldwide as a popular crop as it is sought out as a renewable and sustainable resource for a wide variety of consumer and industrial products. Hemp that is grown for fiber, grain oil, or as an intended health supplement contains less than 0.3% tetrahydrocannabinol (THC). When hemp is grown to produce cannabidiol (CBD) as an intended health supplement, CBD concentrations are relatively high, with concentrations ranging between 8-15%. Hemp for CBD production is grown more intensively, similar to vegetable production, and can be grown indoors or in the field. To help farmers succeed, agronomic research on hemp being grown for CBD extraction is needed in our region. In 2019, the University of Vermont Extension’s Northwest Crops and Soils Program evaluated three plant spacing arrangements (1x1’, 3x3’, 5x5’) and planting dates (10-Jun, 17-Jun, and 24-Jun) to determine best management practices for hemp grown for CBD production in this region.
