| In order to evaluate the effect of two Nicosulfuron and Foramsulfuron herbicides in comparison with common corn herbicides an experiment was conducted during 2010 cropping year in Shoushtar. This experiment designed as a randomized complete block with four replications. Experimental treatments were consisted of Foramsulfuron 1.5 lit ha-1, Foramsulfuron 2.5 lit ha-1, Nicosulfuron 1.5 lit ha-1, Nicosulfuron 2 lit ha-1, Atrazin 1 lit ha-1 + Lasso 4 kg ha-1 and control plot with no control. Results indicated that the effect of herbicide treatments on weed number and dry weight was significant in 1% probability level. The lowest weed population and the dry weight and also the highest weed control efficiency (WCE) was belonged to Nicosulfuron 2 lit ha-1. The difference between this treatment and Foramsulfuron 2.5 lit ha-1 treatment was not significant as regards to weed number. Nicosulfuron 2 lit ha-1 herbicide efficiency in weed control was higher than other treatments especially the combination of Atrazin and Lasso herbicides. Nicosulfuron 2 lit ha-1 herbicide controlled, narrow leaf soruf weed, Oyarsalam and also broad leaf pursalane weed with high efficiency. The highest grain yield on corn was belonged to this treatment that had meaningful difference with other treatments. Higher grain yield in Nicosulfuron 2 lit ha-1 treatment was due to increasing grain number per ear and 1000-grain weight. |
