Abstract. The use of chemicals in agriculture has a negative impact on the environment, soil, and the yield and quality of harvests. The purpose of this research was to study the effect of a microbial consortium based on lactic acid bacteria and yeast on the productivity of several important agricultural crops. The microbial consortium was obtained by co-cultivation of Lactobacillus casei, L. plantarum, L. lactis, and Saccharomyces cerevisiae. Methods. The microbial consortium (1 L/ha) was used to treat crops of wheat, corn, soybeans, and rapeseed 1, 2, or 4 times during the growing season compared to treatment of the same crops with water and a widely used microbiological preparation (“Baykal EМ-1”). Results. A single application of the microbial consortium increased the yield of the treated crops by 25–38 %, while treating the crops in 2 or 4 times affected the quality of the crop rather than its quantity. An increase in protein content of 1.2–3.1 % and oil content of 2.2–4.3 % was observed. The increasing for mineral elements was such as: for copper by 20 %, for zinc by 18.2% and for manganese by 34.4 %. Treatment with the microbial consortium increased the protein yield for wheat, corn, and soybean by 30.2–72.1 % and increased the oil yield for soybean by 30.2–31.7 % and for rapeseed by 40.2–47.7 % depending on the number of treatments. The scientific novelty. The microbial consortium with Lactobacillus casei IMB B-7343, Lactobacillus plantarum IMB B-7344, Lactococcus lactis IMB B-7352 and Saccharomyces cerevisiae IMB Y-5046 has been demonstrated the effectiveness for the first time in production conditions, associated not only with an increase in yield, but also with its quality.
