Abstract
The study was conducted to determine the competitive ability of different density levels ( 0, 5, 10 and 15) of D. aegyptium L. against transplanted rice and to determine the yield loss of rice under saturated and flooded conditions.
Results of the study showed that the interaction between water conditions and density levels of D. aegyptium L. had no significant effect with each other. This means that the interaction of different density levels of D. aegyptium L. under different water conditions had no significant contributions on plant height, number of leaves, tillers, yield components and percent yield loss of rice or vice versa. Competitive ability of rice as affected by different density levels alone found significant on number of tillers panicles, fresh weight and dry weight of rice plant. On the other hand, competitive ability of rice as affected by different water conditions alone produced significant effect in number of leaves, tillers, filled grains and fresh and dry weight of rice plant. Percent yield loss was found significant under different water conditions (flooded and saturated) with 2.87% and 19.34% respectively.
