Abstract
Planting of 10 or 15 days old seedlings did not differed significantly on grain yield of rice. Among weed management practices SRI method of planting with four times cono-weeding at 10 days interval starting from 10 days after transplanting recorded significantly higher grain yield (6003 kg/ha) and was found effective in weed control. However, pre-emergence application of butachlor + one hand weeding at 20 DAT was equally effective alternative weed control in SRI method of cultivation.
