A field experiment was conducted for two consecutive wheat seasons of 2005-06 and 2006-07 at crop research centre, GBPUA&T, Pantnagar on sandy loam soil to find out the effect of establishment methods and weed management practices on weed dynamics and productivity of wheat grown after harvesting of rice. Wheat was infested with Phalaris minor, Melilotus indica, Medicago denticulate, Chenopodium album and Rumex acetosella in weedy check at 60 days after sowing (DAS). Zero till sown wheat had significantly lesser infestation of all weeds except Rumex acetosella than other wheat establishment methods. Hand weeding twice at 35 and 55 DAS was most effective to minimize the weed density and their dry weight under all the wheat establishment methods. Zero till sown crop led to recorded significantly higher grain yield than other establishment methods, however, hand weeding twice was most effective in increasing the grain yield.
