| Abstract | A pot experiment was carried out to evaluate the competitive interactions between rice cultivar (Daylamani) as grown together with barnyardgrass (BYG) or rice barnyardgrass (ECPH) in a Replacement Series Study. The experiment was conducted as a randomized complete block design with a factorial treatment arrangement and three replications. Factors were two species of Echinochloa genus (barnyardgrass and rice barnyardgrass) and five rice: BYG or rice: ECPH mixture proportions (8:0, 6:2, 4:4, 2:6 and 0:8). Relative yield total of aboveground dry weight and root dry weight showed that rice was competing for the same resources with barnyardgrass or rice barnyardgrass. In general, replacement series curves and relative crowding coefficient (RCC) values demonstrated that rice cultivar Daylamani and BYG had equal competitive ability, while Daylamani was more competitive than rice barnyardgrass. Moreover, this experiment indicated that the competitive ability of BYG was higher than that of ECPH. |
