The use of biological preparations in the technology of seed hemp cultivation

Innovative techniques in the technology of cultivating a new variety of hemp Lyudmila are considered. On average, over the years of research, protective measures to prepare seeds and the site for sowing had a positive effect on the yield and quality of hemp products. Seed yield on average for the options varied from 0.99 to 1.26 t/ha; in the options with Sternifag, WP treatment, the indicator was 1.17 t/ha, which is 0.03 t/ha higher than the option without treatment. With treatment options, a significant increase in seed yield was noted - from 0.09 to 0.25 t/ha. The greatest effect was obtained when treating with the biological preparation Baksis, L (an increase of 0.20 t/ha on average). The oil content of hemp seeds varied on average from 29.05 to 32.32%. In the seed protection options, oil content indicators increased from 30.19 to 32.24%, in the control – 30.09%. The highest protein content (29.35%) was obtained in the variants with treatment of the area before sowing with Sternifag, WP, the protein content increased by 0.99–2.08% depending on the treatment option. The content of total fiber in hemp stems ranged from 28.5 to 33.9% (4.0–5.6 t/ha), long fiber - from 15.7 to 22.6% (2.5–3.8 t/ha). The maximum values of total fiber were obtained with the treatment option Celest Top, SC (32.5 %, or 4.8 t/ha) and Baktofit, WP (32.25%, or 4.8 t/ha), long fiber - with the option with Baksis, L (18.55%, or 3.5 t/ha).
