The effect of different sowing density on the yield and quality properties in second crop hemp (Cannabis sativa var. sativa.) cultivation in Tokat conditions

In this study, it was aimed to increase the yield per unit area by determining the appropriate planting method for fiber and seed production in the second crop cannabis cultivation. This research was carried out in 2019 with Narlısaray cannabis variety in Tokat-Kazova conditions. The study was carried out in three replications according to the split plots experiment design in random blocks. In the study, 3 different row spacings (20, 30, 40 cm) were applied in the main plots and 3 different seed numbers per square meter (100, 150, 200 seeds/m 2 ) were applied in the subplots. In the study, the findings of emergence rate, flowering time, plant height, technical stem length, dry stem yield, fiber yield, fiber rate, thousand seed weight, seed yield and oil rate were evaluated. According to the obtained findings; As the number of plants per unit area increases, plant height, technical stem length, biomass yield, dry stem yield, seed yield and fiber yield increase, thousand seed weight and oil rate decreased. Plant height, technical stem length, fiber yield and ratio. According to the sowing densıty applications; the highest average fiber yield was obtained from 315.6 t/ha to 20 cm row x 200 seeds/m 2 , and the average highest seed yield was 135.6 t/ha to 40 cm rows x 200 seeds/m 2 per square meter.
