The system of integrated weed control in maize and soybean has been theoretically substantiated, developed and implemented. It was found that the formation of weeds in maize and soybean on tillage methods (plowing, disking and no-till technology) occurs mainly in the first 30 days after sowing (88-93 %). In maize before application of post-emergence herbicides, the largest amount (458 pcs/m2) was recorded against the background of disking, while in plowing and no-till technology, respectively, 318 and 294 pcs/m2. In soybean, these indicators of tillage, respectively, were 482; 422 and 254 pcs/m2. With the spraying of corn with herbicides on all tillages and no-till technology, the level of weeds was reduced by 90-94 %. The yield of corn grain for the application of herbicides for plowing was 11,50-11,88 t/ha, and for disking and no-till technology the level of corn yield was lower by 0,94-1,16 and 0,39-0,67 t/ha respectively than for plowing. With the use of herbicides, weed control in soybean was 91-93 %. The highest level of soybean yield was observed in herbicide plots with plowing – 2,39-2,49 t/ha, which is 42-50 % more than in the control without herbicides. Application of herbicides by no-till technology contributed to the formation of soybean grain yield in the range of 2,27-2,40 t/ha, which is 38-46 % more than in areas without herbicides. The lowest soybean yield in two years was observed for disking, namely 2,20-2,34 t/ha, which is 0,15-0,16 t/ha less than for plowing. Carrying out weed control measures in maize and soybean is an economically feasible method, both for plowing (plowing to a depth of 20-22 cm), disking (disking to 10-12 cm) and no-till technology.
