Competitive cultivars had faster height growth and leaf area development, and higher dry matter production than the non-competitive cultivars in the unweeded plots. Removal of weeds resulted in even better growth and development in competitive than in non-competitive cultivars. Reduction in height, tiller number, leaf area index and dry weight were greater in non-competitive cultivars than in competitive cultivars. Grain yield were not significantly different among rice cultivars when plots were left unweeded. When plots were weeded, Vandana, Aus 257 and IRAT169F 10/6 yielded higher than P5589-1-1-3P
