Abstract: In order to investigate the response of potato cv. ‘Kufri Sadabahar’ with respect to various doses of zinc sulphate (15, 20 and 25 kg/ha) as basal and split application, field experiments were conducted during winter season of 2014-15 and 2015-16 at Vegetable Research Centre, G.B. Pant University of Agriculture & Technology, Pantnagar, Udham Singh Nagar, Uttarakhand. The pooled data indicated that dry leaf weight (0.89g) at 75 days after planting (DAP), number of tubers (11.50 per plant) at de-haulming, weight of tubers (558.33g per plant) at de-haulming and tuber yield (47.24 kg per plot) were maximum under treatment T7 (zinc sulphate @ 25 kg ha-1 as basal). The maximum total chlorophyll content (1.23 mg/g) was recorded under treatment T7 (zinc sulphate @ 25 kg ha-1 as basal) at initial stage of growth i.e., 45 DAP, whereas, it was maximum (1.10 and 0.86 mg/g) under treatment T9 (zinc sulphate @ 12.5 kg ha-1 as basal and 12.5 kg ha-1 at the time of earthing up) during 60 and 75 DAP, respectively. Results also indicated that the emergence per cent was statistically non-significant at 30 DAP. Based on present study, it can be concluded that zinc sulphate application as basal and/ or split at 25 kg/ha increases plant growth and yield of potato cv. ‘Kufri Sadabahar’ under tarai region of Uttarakhand.
