In this thesis, we studied the agronomic properties of eight varieties of industrial hemp ('USO31', 'Fedora 17', 'Santhica 27', 'Santhica 70', 'Futura 75', 'Monoica', 'Tiborszallasi' and 'KC Dora'). We measured the content of cannabinoids CBD, CBDA, Δ9THC, THCA in the flowering and ripening stage. The experiment took place between May and September 2019 on the farmland of Biotehniška fakulteta, Ljubljana. We used two densities of sowing: 200 seeds/m2 and 300 seeds/m2. During the experiment, we measured the number of plants at the germination stage. We measured the number of plants, stem's height, and stem's weight at the harvest. Samples were taken from the upper inflorescences, then dried in an agronomic oven, and prepared for sampling based on the HPLC method. Smaller sowing density positively affected germination and crop size: 200 seeds/m2 gave us a higher number of harvested plants. Similarly, smaller sowing densities contributed to the higher height of the plants. The highest number of plants at germination and harvest had the 'Tiborszallasi' variety and the tallest height 'Futura 75' variety. The most significant weight had the 'Fedora 17' variety at the density of 300 seeds/m2; the final weight was 6830 kg/ha, above average compared to other varieties. Cannabinoids content fluctuated quite a bit among different varieties, but we measured the highest content at harvest. The highest percent of CBDA had the 'Tiborszallasi' variety, and the highest percentage of CBD had the 'Futura 75' variety. The highest percent of THC had the 'Tiborszallasi' variety which had an almost identical content of THC in the flowering stage (0,106%), and at the harvest stage (0,105%).
