Abstract. The purpose of the research was to study the effect of the experimental preparation based on live bacteria Lactobacillus buchneri on the parameters of sown oats in soil and climatic conditions of the North-West Russia. The objectives of the work were to evaluate the effect of the experimental preparation on the growth parameters of plants, as well as grain yield of the crop. Methods. The experiment was carried out in the framework of microplot field trial in 2020–2022 in Vologda Research Center of RAS. The object of the study was sown oats of Lev variety. Before sowing, seeds of the experimental variant were inoculated in the working solution of the experimental preparation at a concentration of 1 ml of the preparation per 1 liter of water for 2 hours; the content of live bacteria of the original strain was at least 1 × 108 CFU in 1 ml of the preparation. Secondary application of bacteria was carried out on vegetative organs of plants in tillering phase (in concentration of 1 liter of preparation per ha). Scientific novelty. The study of the preparation based on bacteria Lactobacillus buchneri on sown oats was carried out for the first time. Results. The application of the experimental preparation promoted the activation of growth processes of oats, as evidenced by slightly higher weight indices of experimental plants relative to the control. The research results show the increase of crude and dry weight of experimental plants relative to control plants in the heading phase by 18–37 % and by 16–48 % respectively, as well as the increase of photosynthetic pigments content in leaves of experimental plants relative to control by 11–21 %. Grain productivity of experimental oat plants exceeded the control by 13–29 %. In general, the preparation revealed better efficiency of action in seasons with wetter and warmer conditions (2020 and 2022).
