The experiment was conducted to study “ the effect of different weed management practices on growth and yield of potato (Solanum tuberosum L.) cv. Kufri Jyoti” at Crop Research Centre, SGRR (P.G.) College, Dehradun, Uttarakhand during the rabi season of the year 2017-18. The experimental field was laid out in Randomized Block Design with 3 replications of 8 treatments. The results indicated that days to 50 per cent emergence was significantly earliest (11.57) under Treatment T1 (S Metolachlor @ 0.12 kg/ha as Post-emergence) than other treatments, whereas plant population per meter2 was statistically non significant under the all treatments. The maximum plant height (39.40 cm and 41.60 cm) was observed during later stage of plant growth i.e., 45 and 60 days after planting, respectively, under Treatment T3 (Metribuzin @ 0.4 kg/ha as Pre-emergence). The average weight of tubers per plant and tuber yield per plot (275.33g and 27.57 kg) were found maximum in treatment T5 (Prometryne @ 1.0 kg/ha as Pre-emergence). Thus, it can be concluded that the maximum yield and net return was recorded in T5 (Prometryne 1.0 kg/ha pre- emergence) over other treatments. Hence the treatment T5 (Prometryne 1.0 kg/ha pre- emergence) could be recommended for weed management in potato.
