As a consequence of the adverse effects of weed loss yields make up 28-45%, and in many cases even more. The competitive activity of weeds in stressful conditions is maximally strengthened, especially in conditions of insufficient soil moisture and high air temperature. According to the results of researches, the use of precipitate loosening of soil reduces obesity by 2.8 times and increases the yield of spring barley by 0.6 t / ha or 15,4% compared with the option without protection measures. The combination of multi-row loosening and herbicide reduced 9,4 times the infestation and increased the yield of root crops by 13,3 t / ha or 24,2%. Thus, a combination of agronomic and chemical measures to control weeds proved to be effective, in which the weeds were destroyed in the early phases of development, the depletion of crops during vegetation decreased, the agrophysical properties of the soil were optimized, which contributed to the increase of crop yields.
