Andriyetc D. Management of soybean productivity according to intensification of cultivation technology under conditions of right-bank Forest–Steppe of Ukraine

DThe thesis presents the results of research of the agrometeorological conditions impact and application of the colloidal solution of metal nanoparticles on ultra-early maturing soybean varieties Annushka and Ustya. Positive influence of presowing treatment of seed, application of nitrogen mineral fertilizers in medium rates and colloidal solution of metal nanoparticles on soybean productivity was established. Treatment of seed with «Rizogymin» and application of mineral fertilizers at rate N60P60K60 provides yielding capacity 3,69 t/ha for Annushka variety and 3,20 t/ha for Ustya variety, the average for 2008-2010. The following increase in rates of mineral fertilizers application up to N120 on the background of P60K60 mitigates influence of seed treatment on soybean yielding capacity formation. Application of the colloidal solution of metal nanoparticles in concentration 240 mg/l at buds stage favors to increase in yielding capacity that makes up 3,11 t/ha for Annushka variety and 2,66 t/ha for Ustya variety.
