Furman O. Optimization of soybean growing technology elements in the conditions of the Right-Bank Forest-Steppe.

Object - the processes of growth and development of plants of soybean varieties of different maturity groups, crop formation and its quality depending on the biological characteristics of the variety, inoculation and mineral fertilizers. The aim is to identify the dependences of growth, development and productivity of soybean varieties of different maturity groups from inoculation, norms and terms of mineral fertilizers application and to improve the technology of their cultivation on the basis of bacterial-mineral fertilizer in the right-bank forest-steppe. Methods: visual, quantitative, measuring and weight, calculated, biochemical, dispersion, statistical and mathematical, comparative calculation. As a result of research conducted during 2013-2015 in the Forest-Steppe right bank on black soil typical low-humus medium loam, the peculiarities of the effect of bacterization of seeds with a microbial preparation based on nitrogen-fixing and phosphorus-mobilizing bacteria and different norms and terms of mineral fertilization on plant growth and growth soybean seeds. The dependence of the formation of photosynthetic, symbiotic and individual productivity of culture on the influence of factors that were the purpose of research. The technology of growing soybean varieties based on the optimization of bacterial and mineral fertilizers has been improved. The improved technology of soybean cultivation in 2016 passed the production test and during 2017-2020 was implemented in the State Enterprise "Experimental Farm" Ozerne" IBCaSB NAAS, Bila Tserkva district, Kyiv region and Bila Tserkva Research and Breeding Station IBCaSB NAAS, p. Mala Vilshanka, Bila Tserkva district, Kyiv region on the total area of 98 hа, where it provided the average yield of soybean seeds at the level of 2,68-2,96 t / ha with an average yield in farms – 2,27-2,31 t / ha. Field of use - agricultural production.
