Abstract :
Abstract To evaluate the effect of several herbicides on weed control and yield components and yield components of three maize cultivars, a split plot experiment was conducted in a randomized complete block design with four replications. The herbicide including control (H1=non-herbicide),H2= erydicans,H3= erydicans and 2.4.D,H4= lassou + 2.4.D in main plots and cultivars including V:v1= 604,v= 647 and v3= 700 were investigated in sub plots. The results showed that the highest yield of corn with an average of 9.683 tons per hectare was obtained from post-emergence consumption of Laso2.4.D, and the results showed that the effect of herbicide treatment on weed dry weight, weed density Weeds are meaningful. In this experiment, the true leaf area, dry weight of the leaf and the number of true leaves of corn in relation to herbicide were investigated. The highest dry weight and true leaf area were obtained for stage D7 (105 days after planting) and the highest number of true leaves in stage D3 (45 days after planting). Therefore, this combination treatment is recommended for effective control of weeds, especially in the early period of corn growth, which has a low competitive ability. Key words: weed.
