The article presents the results of three years of field research on studying of influence of ways of the basic processing of soil and systems of applied fertilizers on productivity of grain crops. The experiment considered winter wheat, cultivated on black steam, and is itself a precursor to the Sudanese grass. Three variants of the main tillage and four variants of the use of mineral fertilizers in the cultivation of winter wheat varieties of local selection of reed 3 were studied. Field experiments were conducted at the STC of Volgograd state University "Gornaya Polyana" on light chestnut soils from 2016 to 2019. As a result of studying the productivity of winter wheat in rainfed conditions on light chestnut soils of the Lower Volga region, it was found that the maximum values of biometric indicators, elements of the structure of the crop, biological and economic productivity were obtained during its cultivation by deep chisel processing by the working bodies of the "Ranch" with the use of ammophos and potassium chloride during sowing and early spring feeding with ammonium nitrate. The minimum values of biometric indicators, elements of the structure of the crop, biological and economic productivity are obtained by cultivating it on a small disk processing without the use of fertilizers.
