Abstract
The dominant weed nora were Echinocloa colona (L.), Cyperus difformis L. and Ammania braccifera (L.) Rottb. Intensive puddling with continuous submergence recorded the lowest density and dry weight of wceds with 40% increased grain yield over normal puddling with irrigation at one day after disappearance of ponded water. Among the weed managcment practices, oxadiargyl at 75 g ha−1 supplemented with HW at 40 DAT recorded the lowcst density and dry weight of weeds with higher weed control efficiency and grain yield, which was comparable with hand weeding twice scheduled at 20 and 40 DAT. On an averagc, oxadiargyl at 75 g h−1 supplemented with HW at 40 DAT registered 39.5% higher grain yield as compared to unweeded control. Cinmethylin at 75 g ha−1 was least effective in controlling the weeds. Intensive puddling with continuous submergence combined with oxadiargyl at 75 g ha−1 supplemented with HW at 40 DAT was the best integrated weed managcment practice to achieve broad spectrum weed control and higher grain yield in transplanted rice.
