The article presents the results of experimental studies on the influence of different methods and depth of basic tillage at the background of organic and organo-mineral fertilization systems on agrophysical properties of soil, its water regime and yields of the cultivated crops. The goal of the study was to scientifically substantiate the optimal parameters of the systems of basic tillage and fertilization in the row short crop rotation in the conditions of irrigation, which guarantee the improvement of effective fertility of the dark-chestnut soils and reduce the chemical load on the environment. Field, laboratory, statistical and computational methods were used in the study conduction. Optimal parameters of agrophysical conditions, both at the beginning of vegetation and before harvesting, were formed by differentiated-1 system of basic tillage where during the crop rotation we alternated shallow plowless tillage for the crops of the Steppe ecological type with combined disc-chisel loosening to 38-40 cm for grain sorghum. As a result, the most favorable conditions for growth, development and crop formation are created by differentiated-1 system of basic tillage under fertilization with by-products and mineral fertilizers application in the dose of N₁₂₀P₆₀ kg/ha. Differentiated by ways and depth system of basic tillage with one para-plowing per the crop rotation contributed to the formation of the highest productivity of the crop rotation: under organic fertilization system – 3.71 t/ha of grain units; under organo-mineral, with the application of N_82.5P₆₀ per the unit of the crop rotation area – 6.92 t/ha; and under organo-mineral, with the application of N₁₂₀P₆₀ – 8.50 t/ha. The mentioned cultivation technology guarantees obtaining the best profitability level of 110.1%.
