Twenty five dicot and seven monocot weeds belonging to 16 familieswere recorded in silver oak plantation. Weeds of Asteraceae, Malvaceae(among dicot) and Poaceae (among monocot) families were found inthe plantation. Among weed control treatments in silver oak plantaion,black polythene mulch recorded significantly lower dry weed biomassand higher weed control efficiency at different intervals of observations,i.e., two, four and six months after treatment imposition. Almost 99per cent of reduction in weed biomass and (98.98 %) weed controlefficiency observed in black polythene mulch treatment as comparedto the control.
