A pot experiment was conducted to study the effect of Echinochloa crusgalli and Echinochloa colonum on the growth and yield of rice (cv. IR50) during April to July 2002. The results showed that the effect of two weeds pot G 1 produced 70.6% yield loss of rice grain and about 97% grain yield was reduced when 8 weeds competed against a single rice plant. The reduction of rice grain at this density was the results of 42.9% reduction of plant height, 92% reduction of LAI, 72.7% reduction of tillers plant G 1, 88.5% reduction of panicles/plant and 63.8% reduction of grains panicle G 1. Further increase of weed density produced the self-thinning effect of weeds and rice yield increased in comparison to 8 weeds pot G1. It was concluded that Echinochloa crusgalli and E. colonum produced similar effects on grain yield and other plant characteristics of rice. |
