THE INFLUENCE OF COMPLEX ORGANOMINERAL FERTILIZERS ON THE YIELD AND QUALITY OF SPRING WHEAT GRAIN IN THE CONDITIONS OF THE ANCESTRAL REGION OF THE REPUBLIC OF TATARSTAN

The quantity and quality of the resulting spring wheat harvests largely depends on the reasonable use of the necessary nutrients in specific soil and climatic conditions. The purpose of these studies is to study the features of the combined effect of organomineral fertilizers with pesticides on the productivity of spring wheat. Field experiments were conducted in 2020-2022 on the basis of AF "Ayu" LLC in the Arsky district of the Republic of Tatarstan. Organomineral fertilizers Bar GumBar Max, Chudozem were used during pre-sowing seed treatment, during the treatment of crops with herbicide in the tillering phase of spring wheat and in the tube phase during the treatment of crops with insecticide. Pre-sowing treatment of seeds with organomineral fertilizers in 2020 and in 2022 had a stronger impact on field germination than in the 2021 dry year. Non-root fertilizing with organomineral fertilizers in the phases of tillering and entering the spring wheat tube increased growth processes, increased the safety of seedlings for harvesting, increased the number of productive stems per unit area, grain weight from 1 ear, grain yield by 20% compared to the control. The use of organic fertilizers Batr GumBar Max contributed to the formation of spring wheat grain with a maximum gluten content in 2020 and in 2022 up to 24%, in 2021 dry year up to 29%. In the same variant, the maximum value of net income per 1 hectare and the lowest cost of 1 ton of grain were obtained.
