Abstract

In order to study effect of competitive ability in some of the cultivars bean (Phaseolus vulgaris L. ) in weed interference, an experiment was conducted at a field in Karaj during 2014 and 2015 growing seasons. Experiment was conducted as factorial bases on randomized complete block design (RCBD) with three replications. Experimental treatments include weeding and no weeding of weeds and five cultivars of bean (Naz, Goli, Sayyad, Derakhshan and Akhtar). Analysis of variance showed that the effect of weed control and cultivars on most of the traits was significant. But, the effect of year and weed control × Cultivar interaction was not significant. Naz cultivar had the lowest weed density and biomass density (17 plant per m-2 and 92 g m-2, respectively). Also, the highest grain yield (261. 81 and 230. 58 gm-2) were obtained at weeding treatment and Naz cultivar, respectively. Also, the results indicated that Naz cultivar had highest competitive index (1. 52) and Akhtar cultivar had the lowest (0. 83). grain yield loss in weeding and non-weeding condition at Naz, Goli, Sayyad, Derakhshan and Akhtar cultivars was 30. 25, 32. 91, 37. 36, 38. 50 and 38. 78 %, respectively. Generally, evaluation of different traits showed indeterminate and runner cultivars (Naz and Goli) showed higher competitive ability compared to determinate and erect cultivars (Akhtar and Derakhshan). So, pay attention to condition of this study, Naz cultivar is suggested for same environments.
