Abstract
The stationary experiment on the comparative study of the direct sowing and traditional cultivation technology was laid in 2015–2016 at the trial field of the FSBSI “Research Institute of Agriculture of Crimea”. Two five-course crop rotations were taken as a base; all fields were included in the crop rotation. During the years of research, we observed mixed weed infestation. No matter what cultivation technology was applied, actual weed flora at the fields with winter crops was represented by overwintering and winter weeds; at the fields with spring crops – annual spring weeds. There were no rootstock grasses and rhizomatous perennial weeds or there were few of them at all fields in the experimental crop rotations both by traditional cultivation technology and direct sowing. Timely and high-quality weed control put the direct sowing on equal footing with the traditional one. It is advisable to change herbicides, their doses, as well as use tank mixes, after moving to a direct sowing system.
