Five-year (2017-2021) studies on a typical deep low-humus black soil at the experimental field of Bila Tserkva National Agrarian University found that the yield of winter wheat and spring barley was almost at the same level with mouldboard and differentiated tillage in the five-field crop rotation. The research was conducted by the method of field stationary experiment. All crop rotation fields are fully deployed in space and time. The area of sown plots was 171 m², accounting area – 112 m². Repetition – three times, placement of repetitions and plots was consistent, systematic. In the tillering phase of winter wheat and spring barley, mouldboard-mouldboardless tillage had the advantage of arable layer moistening. When sowing white mustard, the most moisturized soil layers were under differentiated tillage, the least moisturized – under mouldboardless tillage. The dry mass of root residues of winter wheat was the highest under mouldboard, spring barley – under mouldboard-mouldboardless tillage, and white mustard was almost the same under these cultivation options. Grain yield was at the same level under mouldboard and differentiated tillage. The green mass of white mustard applied in the soil was significantly more under the differentiated tillage and predecessor of spring barley. The highest indicators of economic and energy efficiency were obtained by applying 12 tons of manure + N₉₅P₈₂K₇₂ per hectare of arable crop rotation land (including per winter wheat N₁₂₅P₉₀K₇₀, spring barley N₆₀P₅₀K₅₀, white mustard N₁₅P₁₅K₁₅) and carrying mouldboard-mouldboardless tillage in crop rotation, which involves deep cultivation of 25-27 cm in only one field, and the rest of the fields – mouldboardless and disk shallow tillage.
