Ukraine is an agricultural country, so it is extremely important to use fertilizers that are environmentally safe and efficient. Today, biological products can be an alternative to chemical plant protection products. With their help, we can get yield growth and high quality. The influence of biological products of Bionorma Nitrogen and Bionorma Phosphorus on the productivity of durum spring wheat of the «Isolda» and «Heritage» varieties in the forest-steppe conditions of Ukraine is presented in the research. The varieties used were the most sensitive to fertilizing, which is why they were selected for research. Bionorma Nitrogen is a preparation of free-living and associative nitrogen-fixing bacteria that is used to improve the nitrogen supply of a wide range of crops. The Bionorm Phosphorus includes soil spore bacteria and micromycetes, which are characterized by high phosphate-mobilizing activity. The drug is intended to improve the phosphorus nutrition of crops. Given the conditions of cultivation and the use of these varieties, it is recommended to use the preparations of Bionoram Nitrogen, Bionorma Phosphorus and their combination, because, according to the results of experiments, the plants after the above biofertilizers have high rates of productive stems. It was also found that the «Heritage» variety responded better to the use of biological and fertilizers than the «Isolda» variety
