Abstract :
Crop-weed competition has a profound effect on the seed yield of mung bean. We evaluated the effects of both the seed rate and weeding regime on the weed infestation and crop performance of mung bean. Two factors via seed rate (15, 25 or 35 kg ha-1) and different doses of haloxyfop-R-methyl (0, 0.4, 0.8 and 1.2 L ha-1) were included in the experiment. The experiment was implemented in a split-plot design accommodating seed rate in the main plot and doses of herbicide in the subplot with four replications. Mean data from the experiment showed that weed density and weed dry weight were significantly affected by seed rate: these two variables decreased with the increase in the seed rate (p<0.01). The seed rate significantly influenced plant height, number of pod per plant, biological yield and seed yield. Different variables that included: Plant height, number of pod per plant, 1000 seed weight, harvest index and seed yield were significantly influenced by variations of herbicide doses. Seed yield was significantly improved in dose of 1.2 L ha-1. Overall, the interaction effect of seed rate and herbicide doses was not significant in respect to the plant characteristics except harvest index and seed yield. Nevertheless, a seed rate of 35 kg ha-1, coupled with volume of 0.8 L ha-1, illustrated the best seed yield. Therefore, crop competition can be explored as an effective alternative weed management strategy and achieving optimal yield of bean
