INFLUENCE OF ORGANOMINERAL FERTILIZERS AND BIOLOGICAL PRODUCTS ON THE CONTENT OF NUTRIENTS IN THE BASIC AND SIDE PRODUCTS AND THE PRODUCTIVITY OF SPRING WHEAT IN THE FOREST-STEPPE ZONE OF THE VOLGA REGION

Abstract

The paper presents the comparative effectiveness of mineral and organic fertilizers when combined with biological product and their influence on the productivity of spring wheat. Studies have shown that the combination of manure with pre-sowing treatment of seeds with biological preparations made it possible in this experiment to form a high yield of spring wheat, which varied within 3.48-3.99 t/ha, which is higher than the absolute norm by 0.32-0.83 t / ha.
