Efficiency of humic and mineral fertilizers in the technology of spring wheat cultivation

Abstract

Abstract The article presents the results of studies on the effect of humic fertilizer Gumostim and mineral fertilizers on the formation of productivity of spring soft wheat varieties Tulaykovskaya 108. The work performed allows us to expand our understanding of the effect of humic acid salts in humic fertilizers on the development of spring wheat and give recommendations on methods for their use in order to increase the yield and quality of household products, preserving the ecological cleanliness of the environment. The research objective is to improve the elements of spring wheat cultivation technology under the conditions of the forest steppe of the Middle Volga region, which allow to optimize the conditions of growth and development through the integrated use of humic and mineral fertilizers. Studies have found that the use of humic fertilizer Gumostim increases field germination of spring wheat seeds by 0.8-1.2%, the net productivity of photosynthesis to 5.16 g/m2 × day, ear grain content by 13%, grain weight per plant by 15%, yield by 0.55 t/ha. Mineral fertilizers increase the net productivity of photosynthesis to 5.30 g/m2 × day, ear grain content by 36%, spring wheat yield by 1.01 t/ha. The combined use of Gumostim and mineral fertilizers increases the net productivity of photosynthesis to 5.47 g/m2 × day, ear grain content by 83%, grain weight per plant by 45.8%, spring wheat yield by 1.55 t/ha.
