The protective stimulating properties of microbiological preparations at cultivation of barley on the example of light brown solonetzic soils

In field husbandry the grown-up plants are in multilateral and close connection with surrounding environment. Receiving the maximum efficiency and quality of a crop is possible only at a favorable combination of all factors of plants development and technological discipline. However, the lack of at least one living condition of a plant oppresses its development, and the absence leads to death. The problems of receiving environmentally friendly production, improvement of quality indicators of the final product, cleaning the soil cover of chemistry and heavy metals made relevant ecologically focused systems of agriculture which essence consists in gradual replacement of part of agrochemicals by biological means, and first of all on microbiological preparations. Microbiological preparations have positive impact on accumulation of biomass of plants during vegetation. The efficiency of inoculation depends on the high-quality features of crops, the level of soil fertility, weather conditions and a type of the strains which are a part of a preparation. In this article the author presents the results of research on studying the influence of microbiological preparations on efficiency of summer barley of Nutans 553 in the conditions of the light brown solonetzic soil. According to the results of the conducted research, the best indicators of crops structure and biological productivity were revealed in variaties processed with flavobakteria and mizorin. The 3-year productivity of flavobakteria-processed crops made 4,76 t/hectare that is higher than control norm by 0,37 t/hectare, or 8,3%, and of mizorinprocessed crops amounted to 4,96 t/hectare that is higher than control norm by 0,57 t/hectare, or 13%.
