YIELD AND QUALITY OF GRAIN OF SPRING SOFT WHEAT, DEPENDING ON THE APPLICATION OF HUMIC AND MINERAL FERTILIZERS

Abstract

The article presents the results of studies of the effect of humic fertilizer Humostim and mineral fertilizers on the yield and grain quality of spring soft wheat of the Tulaykovskaya 108 variety. The work performed allows us to expand our understanding of the effect of humic acid salts in the composition of humic fertilizers on the development of spring wheat and to give recommendations on how to use them for increasing the yield and quality of household products, maintaining the ecological cleanliness of the environment. The aim of the research was to improve the elements of spring wheat cultivation technology in the conditions of the forest-steppe of the Middle Volga region, which allow optimizing the conditions of growth and development through the composite application of humic and mineral fertilizers. The studies have established that the greatest increase in spring wheat productivity was observed in the variants with the introduction of mineral fertilizers and the treatment of seeds and crops with the drug Humostim (1.55 t/ha). Mineral fertilizers significantly increased the mass fraction of protein in spring wheat grain by 2.3%, the mass fraction of crude gluten by 4.14%. Humic fertilizer Humostim slightly increased the quality indicators of grain. The highest level of profitability (81%) was noted in the variant with the treatment of seeds and vegetative plants with humic fertilizer Humostim. The use of mineral fertilizers for a projected yield of 4.0 t/ha led to a decrease in profitability by 16.2%.
