Various species of nitrogen-fixing microorganisms were used in the investigation. The effectiveness of the studied species of nitrogen-fixing microorganisms depended on the nitrogen-fixing microorganisms and plant genotype and on the quantity of mineral nitrogen applied. The best and the worst effectiveness of the studied nitrogen-fixing microorganisms was achieved with the varieties PKB-111 and PKB-Lepoklasa, respectively. Azotobacter chroococcum and Beijerinckia Derx expressed the best effectiveness with PKB-Lepoklasa and PKB-111, respectively. Increased quantities of mineral nitrogen decreased the effectiveness of the studied species of nitrogen-fixing microorganisms. The application of highly effective nitrogen-fixing microorganisms in winter wheat can substitute a certain quantities of mineral nitrogen by biological nitrogen and increases yield.
