Abstract
The paper proves that crop rotation and cotton monoculture turned out to be the best agro technical measures in reducing the number of weeds against the control variant which was found by the authors as a result of long-term studies of cotton crop rotations. The results of the studies showed that permanent cotton crop without and with mineral fertilizers in the absence of crop rotation contribute to a significant increase in the number of annual and perennial weeds. Development of crop rotations with strict alternation of cotton with the main predecessors in the cotton complex, as well as appropriate agro-technical measures significantly reduce the weed infestation of cotton field during the entire cotton growing season.
