RESEARCH OF WEED INFESTATION OF WINTER WHEAT CROPS DURING CROP ROTATION

Abstract

The article studied the influence of crop rotations on weed infestation of winter wheat crops. Winter wheat, as the second crop in the crop pattern, is usually cultivated in two cropping systems: in continuous and two-field crop rotation. Based on this, the purpose of this study was to organize constant crop rotations in an experimental agricultural farm. Crop rotations, as a cropping practice, are a complex category with wide impacts on soil and crops. This paper presents the results of the impact of various crop production systems (crop rotation and continuous cultivation) on the weed community in winter wheat crops during two years of research (2019/2020 and 2020/2021). Crop rotations, especially three- and two-field rotations, were more effective in suppressing weeds by species and weed biomass than continuous cultivation.
