 According to the results of the research, it was found that soil moisture for a while sowing of corn was higher in the variants where plowing was carried out with deepening. In the phase of waxy ripeness of corn, higher humidity in substratum soil layer is marked on the variants where it was produced loosening. In a soil layer of 0-30cm, depending on the methods of basic tillage, bulk density was 1.22–1.29 g/cm3 and was lower on variants with 4 loosening the bottom layer of soil. In the phase of wax ripeness of this cultures, the bulk density in the soil layer of 0-30 cm was 1.33-1.36 g/cm3 and also was lower on variants with loosening of the soil layer. The total duty cycle at the time of sowing corn was 50.7–53.4% and was higher by 1.6–5.3% in the variants where medium plowing was carried out (by 20– 22 cm) and plowing with loosening of the soil layer, and air capacity soil optimal. A significant increase in the yield of corn grain was obtained on options where plowing was carried out at 20-22 cm, plowing at 20-22 cm + loosening at 12-14 cm, deep plowing without rotation of the slice (25-27 cm), with the highest grain yield was ensured by plowing by 20-22 cm + loosening by 12-14 cm. The highest level of profitability (60.2%) was provided by plowing at 20–22 cm + loosening 12-14 cm below the level of plowing. Higher energy equivalent (by 5.0 - 17.2%) compared to others treatments marked on the variant where plowing was carried out 20-22 cm + loosening 12-14 cm below the level of plowing.
