Industrial hemp is a non-psychoactive variety of Cannabis sativa L., i.e., it contains less than 0.3% tetrahydrocannabinols (THC). This crop is one of historical importance in the U.S. as manufacturers seek industrial hemp as a renewable and sustainable resource for a wide variety of consumer and industrial products. To help farmers succeed, agronomic research on industrial hemp is needed. In this trial, investigations were performed to determine whether magneto-priming, a form of seed priming that involves magnetic fields, effects the germination percentage of industrial hemp seed. Beneficial effects of magnetic fields on seedling growths and germination have been reported for many different plant species. Dry industrial hemp seed was exposed to static magnetic fields ranging from 65 ± 3 to 505 ± 8 mT for 2 h prior to seed germination. Germination was performed at 13.6 ± 0.7 °C, a temperature that is representative of the germination temperatures of industrial hemp in the U.S. state of Colorado. Magneto-priming of seed had no statistically significant effect on seed germination percentage. View Full-Text
