The purpose of the study was to investigate the efficiency of tillage sys-tems with stubble destructor to increase the yield of sugar beet roots in the for-est-steppe zone of the Middle Volga Region. Studies have shown that tillage systems have a different influence on the productive moisture reserve in the meter layer of the soil. Thus, in the period after the main tillage for sugar beet, the highest values of the indicators were observed in the variants with non-mouldboard and minimum shallow systems. However, it should be noted that the differences by year were not always reliable. In the period of physical ma-turity of the soil, the values of the indicator did not change in the experimental variants. When the sugar beet rows were closed, there was a tendency for the productive moisture reserve to decrease in resource-saving tillage systems. In the variants with non-mouldboard tillage system by 2.6, with minimum shal-low tillage by 13.1 mm. Soil moisture was most effectively used by the plants in the variants with mouldboard tillage system. The highest sugar beet yield (44.52 t/ha) was observed in the variants with a mouldboard tillage system. There was a significant decrease in yield of 3.33 and 5.43 t/ha for the non-mouldboard and minimum shallow tillage variants, respectively. The use of the stubble destructor in the variants with mouldboard tillage significantly in-creased the sugar beet yield by 0.38 t/ha; with non-mouldboard tillage – by 0.67 t/ha; with minimum shallow tillage – by 0.87 t/ha. On average over the three years of research, the highest level of profitability was observed with the mouldboard tillage system with the use of the stubble destructor Effect Bio.
