Abstract:
When growing irrigated grain sorghum in the grain-row crop rotation under the conditions of the Southern Steppe of Ukraine, a differentiated system of basic soil tillage is economically and ecologically sound. It involves (once in the rotation of crops in the crop rotation) combined disk-chisel loosening under grain sorghum at a depth of 12-14 cm with soil slitting up to 38-40 cm against the background of mineral fertilizers (N90P60) and winter wheat plant residues as fertilizers. Over the years of research, the system provided an average annual profitability level of 210 -218% per one hectare of crop rotation area compared with the control (160-184%).
