Abstract :

To study the effect of herbicides on weeds control and yield and yield components of three corn cultivars,  an experiment was conducted in split plot experiment based on randomized complete block design with four replications. The herbicides included Eradican, Eradican + 2,4-D, and Laso + 2,4-D assigned in main plots and maize cultivars included SC604, SC700, and SC647 SC were placed in in subplots. The effect of herbicide on dry weight of weed characteristics was significant. The lowest weed dry weight per square meter was obtained from the treatment of Laso + 2,4-D. In comparison to other herbicide, this herbicide also had more efficiency in weeds control.  Grain yield, ear length and ear diameter were also influenced by herbicide. The effect of cultivar on 1000-grain weight was meaningful and SC647 had higher production capacity compared to other cultivars. The highest yield of corn was obtained from combination treatment of post-emergence of Laso and 2,4-D. Therefore, it is recommended to use this treatment because of the effective control of weeds, especially in the early period of corn growth, which has little competitive ability.
