The effect of bacterial complexes consisting of nitrogen-fixing, phosphate-solubilizing and potassium-solubilizing
microorganisms upon yield of spring wheat was studied. As a result of the research, the effect with the pre-sowing
treatment of seeds using nitrogen-fixing together with potassium-solubilizing microorganisms was obtained, where the
yield increase relatively to the control was 0.5 t/ha, the field germination increased. The seeds treated before sowing and plants on shoots were the most resistant to harmful diseases – brown rust (Pucciniareconditaf. sp. tritici Rob. ex Desm.) and Septoria disease (Septoria graminum Desm.), as well as Fusarium disease (Fusarium graminearum Schwabe). The number of nitrogen-fixing, potassium-solubilizing and phosphate-solubilizing bacteria in the soil in the phase of wax ripeness of grain increased.
