【 摘 要 】

In conditions of the northern steppe of Ukraine, while cultivating winter wheat after corn in clean fallow the expediency of shallow mulch tillage (disk, flat-cut (early fallow)) has been justified, which provides obtaining equivalent biometric indicators of plant growth and development, grain yield compared to the fall-plowing (the yield of grains for plowing is 5,24-5,50 t/ha, the disking is 5,17-5,60 t/ha, flat-topping loosening (early fallow) – 5,04-5,52 t/ha) on the organic and mineral background (stubble residues + N30-60P30K30). The autumn disk and spring flat-cut cultivation of the fallow field on the background of applying N30-60P30K30 ensure the annual yield of high quality grain of the 3d class (protein – 11,6-12,3%, gluten – 22,6-24,6%), and also contribute to fuel economy during soil cultivation – 22-29 l/ha and guarantee high profitability of grain production at the level of 110-123%).
