Abstract: A field experiment was regulated during kharif season of 2014 in Pantnagar (Uttarakhand) to evaluate the nutrient uptake by weeds and growth parameters of transplanted rice (Oryza sativa L.). Treatments comprised of 8 treatments, out of which three were treated with triasulfuron in three different rates i.e. 8, 10 and 12 g ha-1, one was with ethoxysulfuron at 15 g ha-1, one was with metsulfuron methyl at 4 g ha-1, one was with 2, 4-D at 500 g ha-1, and the rest two were weed free and untreated check. Experiment was managed in Randomised Block Design with 3 replications. Among the plots treated with different rates of triasulfuron and other herbicides, the highest crop dry matter was produced by triasulfuron at 12 g ha-1. The highest plant height was recorded in weed free plot while lowest in weedy check at all the stages. Uncontrolled weeds, on an average depleted 43.4 kg N, 4.5 kg P and 14.9 kg K/ha at 90 days after transplanting. All the treatments caused significant reduction in the uptake of these nutrients by weeds over weedy check at 90 days stage of crop growth.
