IMPACT OF BIOPREPARATION ON GROWTH AND YIELD OF OATS IN CONDITIONS OF THE VOLOGDA REGION

The aim of the research was to study the effect of the preparation based on live bacteria strain Lactobacillus buchneri 600 on morphometric and productive parameters of two varieties of sown oats in the conditions of the Vologda Region. The objectives of the work were to evaluate the effect of the preparation on plant growth parameters, as well as grain yield of the crop. The experiment was carried out in the framework of a small-scale field experiment in 2021–2022 in the field of Vologda Research Center of RAS. The object of the study was sown oats of Lev and Yakov varieties. Before sowing, the seeds of the control variant were soaked in water, and the experimental variant was inoculated in the working solution of the preparation at a concentration of 1 ml of the preparation per 1 liter of water for two hours, the secondary application of bacteria was carried out on vegetative plant organs in the tillering phase (at a concentration of 1 liter of the preparation per hectare). The research results showed an increase in crude weight up to 42%, dry weight up to 48% in experimental plants compared to the control depending on the variety and vegetation phase. The growth in the content of photosynthetic pigments in the leaves of experimental plants relative to the control amounted to 11–20%. The increase in growth parameters of experimental plants was accompanied by an increase in their grain productivity by 13–18%. The increase in grain productivity was due to some increase in productive bushiness and grain weight. The application of a biopreparation based on live fermented bacteria L. buchneri 600 contributed to the activation of oat growth processes in the conditions of the Vologda Region.
