Chorna V. Formation of Soybean Seed Yield and Quality under the Effect of Inoculation and Retardant in the Right-Bank Forest-Steppe

The object of research is growth and development of soybean plant varieties having different maturity, yield formation and quality depending on the biological characteristics of varieties, inoculation and retardant. The purpose of the research is to explore the features of formation of soybean seed yield and quality depending on the effect of inoculation and retardant under the conditions of the right-bank Forest-Steppe. Methods of the research: visual, quantitative, measurement method, cutting method, physiological, method of monoliths, method of the test sheaf, method of continuous harvesting, biochemical, statistical, comparative and calculative. Morphobiological structure of soybean plants depending on inoculation and application of retardant in various concentrations is justified in the dissertation; dependencies of the processes of growth, development and formation of the photosynthetic and symbiotic apparatus, value of yield and quality of soybean seed on the effects of inoculation, retardant and hydrothermal growth conditions are identified; the processes of formation of fruit elements and individual productivity of soybean plants are described. Direct correlation between the level of individual and seed productivity of soybean is established. Introduced at the farms of Vinnytsia region on the area of 10 ha. Field of application - agriculture.
