The research was carried out at the experimental field of the North Caucasus Federal Research Center. In the field, years of experience, founded in 2012, in crop rotation of soybean-winter wheat-sunflower-corn all crops cultivated on the recommended scientific institutions technology soil treatment, and these same crops in the same crop turnover has grown by No-till technology. The recommended technology of maize cultivation consisted of soil double tillage by the heavy disk tools to the depth of 0.120-0.140 m immediately after harvesting the previous sunflower, winter plowing at 0.200-0.220 m, early spring harrowing, pre-sowing cultivation and sowing with an Optima seeder. In the No-till technology, the soil was not treated and ten days before corn sowing, the plots were sprayed with a continuous herbicide Rap 600 at a dose of 2 l/ha. The research showed that better accumulation and conservation of moisture can be provided during the flowering of maize with the content in the soil layer of 1.5 m at the depth of 34 mm, or 18.1% more moisture than usage of the technology with tillage which is recommended by scientific institutions. It contributes to a significant increase of 0.42 t/ha, or 12.0% in crop yield by using this technology.
