Abstract
To survey the Effect of different doses of Pursuit herbicides on weed control and yield components of two cultivars of cowpea, an experiment was conducted in the summer of 2012 in Ahvaz climatic conditions. This experiment as factorial based on randomized complete block design with three replications with two cultivars (Mashhadi, Baghdadi) and herbicides was conducted . Herbicide treatments included of three levels of herbicides Pursuit 0.5, 0.75, 1 liters per hectare and two control treatments without weed (Full weeding) and with weed (interference control) was used, To determine the yield and yield components from two rows of 3 and 4 by observing 1 (m) a marginal effects, 4 square meters of harvest and number of pods per plant, number of seeds per pod, 100 seed weight, biological yield, seed yield and harvest index were measured. ANOVA showed that the cultivars in the study, except for 100 seed weight and number of pods per plant, respectively non significant and significant at the 5% probability level Other traits were significant differences in the probability level %1. Also interaction dose ×Cultivars for all traits had significant 1% level indicated that different doses of herbicides has a huge impact on cultivars. also according to the mean comparison table, the highest seed yield and biological yield in full weeding cultivar treatment in order to cultivars Mashhadi with 3894 and 8693 kg per hectare were observed. And finally the best treatment after complete weeding treatment, Pursuit 1 liter treatments per hectare to for pre-emergence It is recommended.
