Abstract
The article presents the results of research on the effect of agrochemical agents used in the crop hemp agrocenosis to protect against weeds on the contamination and economically useful signs of cultivated plants. The experiments were conducted in the Penza region on technical hemp of the Central Russian ecotype of the Nadezhda variety in 2021–2024. The biological effectiveness of protective measures when sprayed with Lontrel Grand and Miura herbicides was 59–77 and 54–86%. With the combined effect of all the factors studied, this indicator was within the range of 64–89 and 77–98%, respectively. Treating seeds with the substances that have growth-stimulating properties allowed for an increase in field germination by 5–7%. Agrochemicals used in various weed control methods have increased the survival rate of hemp plants by 10–16% by harvest time. The weakening of competition between cultivated and weed plant shad a significant positive effect on morphometric parameters. Seed treatment contributed to an increase in the length of the inflorescence by 6–10%, leaf top dressing – by 3.7%. Moreover, spraying the leaves with Izagri Vita caused an increase in stem diameter by 2.4%. The formation of a high increase in the yield of stems (1.47 and 1.50 t/ha) occurred due to herbicide weeding with the studied preparations against the background of treatments of seed material (Artafit, AgroVerm Ekran) and vegetative plants (Izagri Vita). The presented protection scheme, which includes seed treatment and fertilization with a liquid complex fertilizer per leaf, depending on the type of herbicide (against dicotyledonous or monocotyledonous weeds), provided an increase in seed yield of 0.33–0.40 and 0.29–0.41 t/ha.
