Studies on the effect of integrated weed management on transplanted rice indicated significant differences by tillage, plant density and weed control methods but not their interactions. Summer ploughing significantly reduced the weed drymatter, increased productive tillers m^-2, panicle weight, grain and straw yields. Hand weeding twice was found to be superior which was followed by herbicide application combined with hand weeding in suppressing weed density, drymatter and also significantly increased the productive tillers m^-2, panicle weight and grain yield.
