Abstract: Optimisation of mineral nutrition plays a significant role in the productivity of winter wheat (Triticum aestivum L.). Excessive application of mineral fertilisers leads to significant environmental impact and reduced production profitability. The use of biological products based on PGPВ bacteria makes it possible to reduce the application rates of mineral nitrogen fertilisers without compromising yield and grain quality, which is in line with the principles of sustainable agriculture. The impact of the multifunctional biological products Groundfix and Azotohelp on the productivity and quality of winter wheat grain in the conditions of the Right-Bank Forest-Steppe of Ukraine was assessed. The use of biological products ensured optimal crop condition before wintering, as confirmed by a high correlation between the biometric parameters of autumn plant development and subsequent yield (r=0.75–0.90). The maximum efficiency of grain productivity formation was observed with the pre-sowing application of a mixture of Azotohelp and Groundfix, as well as with a combination of seed treatment with Azotohelp (1.5 l/t) + foliar feeding (0.5 l/ha) in the spring tillering phase, which ensured an increase in the number of grains in the ear and an increase in the weight of 1000 seeds by 6.0% (to 49.2–49.4 g). The synergistic effect of the combined use of Azotohelp and Groundfix has been proven, resulting in the highest yield increase — 16.06% relative to the control. The biological action of the preparations is aimed at a balanced redistribution of assimilates, which is confirmed by a decrease in the ratio of by-products to the main product to 0.84–0.87 (compared to 0.96 in the control). The combined treatment of seeds and crops with Groundfix and Azotohelp had a positive effect on the quality characteristics of the grain. The natural weight increased by an average of 9.6 g/l, and vitreousness increased to 58.7%. The crude gluten content increased by 10.4–11.8%. Formation of winter wheat plant productivity when applying Azotohelp (3 l/ha) and Groundfix (1.5 l/ha) during pre-sowing cultivation + Azotohelp (1.5 l/ha), seed treatment with Azotohelp (1.5 l/t) and at the standard rate (0.5 l/ha) during the spring tillering phase were found to be the most effective on average over the years of research. The results confirm the feasibility of using Azotohelp and Groundfix in winter wheat cultivation technology
