The studies were conducted at the experimental base of the Tatar Scientific Research Institute of Agriculture in 1996–2014 to adapt fertilizer systems and basic tillage to achieve yields of 3–5 t/ha. The article cited data on winter wheat – the second crop of the third rotation of the eight-field grain-grass-crop rotation for 2013–2014. We studied the effect of organomineral, organic, mineral fertilizer systems on the winter wheat yield using a differentiated approach to their use in combination with different primary tillage systems (dump plowing to the depth of the arable layer, multi-depth loosening and loosening to a depth of 15–16). The organomineral fertilizer system differed with the saturation with organic fertilizers of 7 t/ha of arable land per year + N36P32K60 according to the balance sheet for receiving 4 t/ha of grain with spring fertilizing using ammonium nitrate, where the yield was 4. 03 t/ha, and the saving on mineral fertilizers, depending on crop rotation and soil saturation with organic matter, was 25–35 %. The yield of winter wheat by the water-saving technology amounted to 4.03 t/ha with a planned level of 4.0 t/ha. At the same time, at the purchase price of 7 rubles/kg, the level of profitability rose to 195.85 %, the cost of 1 center of grain amounted to 236.6 rubles.
