Serevetnik E. Features of varietal technology of soybean cultivation in forest-steppe of the right-bank

The object of study - the processes of plant growth and development of soybean varieties of different maturity, yield formation and quality, depending on the biological characteristics of varieties, method of pre-sowing treatment and period of foliar feeding. Purpose - to develop new methods of high-quality technology of soybean cultivation, to study the reaction of varieties to the system pre-sowing treatment and foliar feeding during ontogenesis in the background of the basic mineral fertilizers in the right bank of Forest Steppe. Methods of research - studies were conducted according to generally accepted standard and scientific methods: hypothesis, experiment, observation, analysis, synthesis, and special methods: field, laboratory, analytical, biochemical, as well as mathematical (variance and correlation), with the definition of bio-energy and economic efficiency of the technology soybean production and its competitiveness. This thesis presents the results of four years of research - soybean varieties of different maturity groups, elements improved technology in interaction with soil and climatic conditions of the right bank of Forest Steppe, mathematical-statistical indicators, bio-energy and economic evaluation of the developed technology elements. Introduced - technology of soybean cultivation techniques of 45 ha in two farms in the Vinnitsa region, which provided seed yield increase at the level of 0.43 - 0.52 t/ha, while the level of profitability was 119-138%. Sphere of use - agriculture.
