Abstract
The results of research on the use of a drug of natural origin as an antistressant to herbicides are presented. Soybean plants, like other crops, are exposed to stress not only from abiotic (spring-summer and summer droughts), but also from anthropogenic factors (pesticide treatments). Experiments were conducted in the northern forest-steppe of the Novosibirsk region in 2020-2021 on leached chernozem. The objects of the study were the humic preparation Cytohumate and soy varieties SibNIIK-315 and Zolotaya. It has been shown that the Cytohumate brown coal antistressant at a rate of 0.4 l/ha improves the physiological state of soybean plants, provides rapid biomass growth and increases crop yield. The humic preparation contributed to the timely passage of the phenological phases of soybean development. Due to the reduction of the stress effect against the background of Cytohumate in 2020, the phenological phases occurred 2–3 days earlier than in the control. In the dry conditions of July 2021, an acceleration of the budding and flowering phases was noted. Against the background of a natural antistress agent in 2020, an increase in soybean height was statistically proven. The use of the humic preparation had a stimulating effect on the biomass of the cultivated plant. This was most noticeable in the wetter 2020, when the biomass in the experimental variant was significantly higher than the control by 16.8 %. In 2021, in the case of using Cytohumate, only a tendency to increase biomass was observed and the differences from the control were 7 %. The yield increase when applying Cytohumate as an antistress agent to herbicides amounted to 0.4–0.5 t / ha of grain.
