PROSPECTS OF SOYBEAN GROWING IN THE WESTERN POLISSIA ZONE

Modern climatic changes, namely significant warming in the northern Forest-Steppe and Polissia zones of Ukraine, provide opportunities for growing a number grain leguminous crops (maize grain, soybeans, sunflower, others), previously unusual this region. Among above-mentioned crops, soybean is crop that can significantly improve nitrogen balance soil without use mineral fertilizers; its cultivation to some extent be an alternative expensive fertilizers because, under condition inoculation, leave up 80 kg/ha biological nitrogen, which equivalent 300 kg ammonium nitrate, enough forming decent harvest winter wheat or corn. The analysis meteorological data shows when having current amount heat supply during season Western zone, it possible grow ultra-early early-ripening varieties with duration 90-100 days required units - 2400-2500 CHU. It was established main factor limiting soybeans on peat soils zone shorter frost-free period (compared adjacent sod-podzolic dry land). Therefore, soils, necessary choose 85 That will allow obtaining physiologically ripe seeds before onset first autumn frosts, years already occur decade September. On yield Yunka variety by variants experiment ranged from 15,1-24,8 t/ha, while light loamy 30,3-46,8 t/ha. reason lower short compared did not studied fully realize their potential 2 row. research has favorable conditions, such as Astor Sevita genetics selection (Canada) 45,0-46,8 Rizofix inoculant combination Rice Pi phosphorus-mobilizing product allows increasing productivity 6,7-7,0 Additional profit about 8-8,3 thousand hryvnias 1 ha.
