Yields and quality indicators of selected hemp varieties (Cannabis sativa L.) grown in Serbia

Abstract

Interest in growing hemp (Cannabis sativa L.) is constantly increasing. Different varieties of hemp grown in Serbia (Institute of Field and Vegetable Crops, Bački Petrovac) were evaluated by plant height, stem yield, fibre content, fibre yield and seed yield. Carmagnola variety reached the highest height, Fedora 17 the lowest. Stem yields, which averaged 13.23±2.93 t/ha, had a high correlation relationship with plant height. The highest and demonstrably most significant fibre content was found in the variety Bialobrzeskia (30.77±0.78%). The fibre yield averaged 3.3±0.64 t/ha. The highest seed fertility was shown by the Novosadska variety. A significant difference (P≤0.05) between 2017 and 2018 in seed production was 51.28 kg/ha. The results of the experiment indicate the importance of the genotype x environment interaction in hemp production.
