Venediktov O. Formation of productivity and qualities of a soybean depending on technological receptions of cultivation in conditions of the Right-bank Forest-Steppe of Ukraine.

The aim is to determine dependence of soybean productivity formation on the tern of sowing, seed treatment and post germination spraying with fungicides in conditions of Forest-Steppe. The object is the processes and tendencies of plant growth and development, formation of photosynthetic, symbiotic apparatus and realizing of seed production potency depending on elements of technology used. The subject is soybean plants and factors of their productivity formation (term of sowing, means of protection against illnesses, hydrothermal resources ). The methods are field experiment, physiological, weighting, biochemical, disperse analysis, correlation-regressive, comparative-accounting; The new approach lies in determination of yield formation and grain quality of soybean depending on tern of sowing, seed treatment and post germination spraying with fungicides. Relation between the level of yield and grain quality and hydrothermal resources of region have been established. Influence of tern of sowing and means of protection against illnesses on level of soybean plants damage by harmful pathogens, forming of individual productivity, yield and grain quality have been proved. The results are that proved competence of technology elements of growing soya bean for grain yield. The thesis has bean introduced at agro-formations of Vinnitsa and Kyiv oblast. The field is Agriculture.
