Abstract
The study was conducted to determine the competitive ability of Panicum repens L. at different density levels ( 5, 10 and 15) under different water conditions ( flooded and saturated) and to determine the yield loss of rice due to the infestation of p. repens. It was composed of four treatments replicated four times with two factors using Randomized Complete Block Design (RCBD). Data were statistically analyzed using ANOVA and treatment means were compared using Least Significant Difference (LSD) at 5% level of significance.
Results of the study showed that the interaction of different water conditions and densities of P. repens L. found no significance in terms of number s of leaves, tillers, panicles, filled and unfilled grains and 1000 grain weight, fresh and dry weight of rice plant. However, significant effect was recorded on plant height. Competitive ability of water condition alone and density of P. repens alone found significant on plant height, number of leaves, tillers, panicles, filled grains and fresh and dry weight of rice plant. On the other hand, there was no significant effect recorded in unfilled grains and 1000 grain weight. Percent yield loss due to the infestation of P. repens range from 6.47% up to 19.95%.
