Abstract: In order to evaluate the manual and chemical methods for weed control in potato crop, a field experiment was conducted during the rabi season of 2014-15 at Vegetable Research Centre, G.B.P.U.A. & T., Pantnagar, U.S. Nagar, Uttarakhand. The experimental field was laid out in Randomized Block Design with 3 replications and 7 treatments out of which treatment T2 (weed free) recorded the maximum plant height (34.15 and 55.17cm) and number of haulms/hill found non-significant at both, 30 and 45 days after planting (DAP) respectively, along with maximum potato marketable tuber yield (353.01 q/ha) followed by treatment T6 metribuzin @ 0.75 kg a.i./ha as pre emergence (305.43 q/ha). However, the results indicated that application of metribuzin @ 0.75 kg a.i./ha as pre emergence i.e., treatment T6 was more effective to weed control whereas, total number of monocot weeds (41.33) and dicot weeds (1.33) were found minimum under treatment T2 (weed free) and T7 (metribuzin @ 0.75 kg a.i. / ha post emergence) during growth stage 60 DAP. Grade wise maximum number of tubers per plot, A grade, B grade, C grade, D grade were found in Treatment T7 (metribuzin @ 0.75 kg a.i./ha post emergence, T7, T2 (weed free), T3 (hand weeding at 30 DAP) respectively.
