The article presents experimental data of research on the influence of various doses of granular fertilizers from turkey droppings on the formation of productivity of spring wheat, conducted in a separate subdivision educational-experimental farm "Ramzay" of Penza State Agrarian University (Penza region, Mokshansky district) in 2022-2023. The studied granular fertilizers were characterized by a nitrogen content of 4.0-4.5 %, a phosphorus content of 3.0-3.5 %, a potassium content of 4.0-4.5 % and an organic matter content of 40.0-42.0%. Research results show that spring application of granular fertilizer from droppings in doses of 500-2000 kg/ha reliably increased the number of grains in an ear and the weight of grains in an ear, resulting in a 12.6-36.7% increase in spring wheat grain yield. The use of seed inoculation and plant treatment at the tillering stage with the microbiological preparations "Azotovit" and "Fosfatovit" increased the efficiency of the applied granular fertilizer doses, while the grain yield of spring wheat increased by 22.5-55.5 % compared to the variant without fertilizers and by an average of 0.37 t/ha compared to the doses of droppings without microbiological fertilizers. As studies have shown, the investigated doses of droppings not only increase the grain yield of spring wheat, but also significantly improve its quality. The protein content increased by 0.67-1.49 %, the gluten content by 1.8-5.0 % and with the use of microbiological preparations these indicators increased by 0.99-1.94 % and 3.1-5.9 %, respectively.
