Abstract: A two year study was carried out in order to explore the response of nitrogen scheduling on leaf indicate, yield and tuber quality of potato (cv. Kufri Sadabahar). The experiment was conducted in a complete randomized block design with three replications at Vegetable Research Centre of GBPUAT, Pantnagar, Uttarakhand, India in Rabi season of 2014-15 and 2015-16. During the study, leaf indicates like leaf area index (LAI), harvest index, leaf chlorophyll content, yield attributes and tuber quality indices were recorded. On the basis of pooled data, treatment T9 (25% N of RDF as basal + 50% top dressing at 25 DAP + one foliar spray of urea @ 3% at 40 DAP) and T1 (50% N of RDF as basal + 50% top dressing at 25 DAP) gave maximum leaf area index (5.0). Maximum chlorophyll ‘a' (0.79 mg/g) and ‘b’ (0.86 mg/g) content was recorded with treatment T8 (25% N of RDF as basal + 75% top dressing at 25 DAP), whereas, highest number of tuber and highest tuber yield per hectare was recorded with treatment T9 (25% N of RDF as basal + 50% top dressing at 25 DAP + one foliar spray of urea @ 3% at 40 DAP). With respect to quality, it was observed that protein content in tuber was increased with increasing nitrogen dose. Highest dry matter content and specific gravity was recorded with treatment T7. However, a maximum total soluble solid in tuber was recorded with treatment T1.
