Abstract. Plants establish direct interactions with various microorganisms living in the soil during growth. As a result, we observe positive or negative effects on the growth and development of plants. During these experiments, we managed to isolate 9 strains of bacteria belonging to the genus Azotobacter by growing nitrogen-synthesizing microorganisms in the soil in an artificial nutrient medium that does not contain nitrogen. It was aimed to reduce the requirement of nitrogenous fertilizers during the growth and development of winter wheat and to supply this requirement to bacteria belonging to the genus Azotobacter with biosynthesized nitrogen.
Keywords: azotobacter, plant, artificial nutrient medium, microorganism, nitrogen-synthesizing microorganisms.
