Temrienko O. Formation of the productivity of soybean varieties depending on inoculation and foliar nutrition under conditions of the right-bank Forest-Steppe

The research object is the processes of growth and development of soybean plants of different maturity, crop production and its quality depending on the biological characteristics of the variety, inoculation and foliar nutrition. The purpose of the research is to reveal the dependencies of growth, development and formation of productivity of soybean varieties of different maturity groups on the inoculation and foliar nutrition and to improve varietal technologies of cultivation on the basis of bacterial and mineral nutrition under conditions of the right-bank Forest-Steppe. The research methods are visual, quantitative, thermostatic-weight and calculation, physiological, biochemical, dispersion, correlation and regression. The thesis presents the research results on the study of the features of plant growth and development as well as formation of soybean seed yield depending on seed inoculation and foliar nutrition. The influence of the factors investigated on the formation of soybean fruit elements and their abortivity is established. The dependence of formation of photosynthetic, symbiotic and individual soybean productivity is revealed depending on the influence of the factors studied. Close correlation and regression relationships between technological techniques and soybean productivity are established. The economic and energy efficiency of soybean cultivation technology based on optimization of bacterial and mineral nutrition is substantiated. The improved technology of soybean cultivation has been tested in the farms of Vinnytsia region on the area of 15 hectares. The industry is agriculture.
