Abstract: In order to evaluate the effect of nitrogen scheduling on grading of potato crop (variety-Kufri Sadabahar) a two year experiment was undertaken during winter season of 2014-15 and 2015-16 at Vegetable Research Center of GBPUAT, Pantnagar, Uttarakhand. The experiment was consisted of ten nitrogen scheduling treatments replicated thrice in Randomized Complete Block Design. All the cultural practices were done under scientific management. During harvesting tubers were graded according to weight in four grades viz. small (<25 g), medium (25-50 g), large (51-75 g) and extra large (>75 g). The seed tuber per cent by number and yield was calculated by taking sum of medium and large grade tubers and convert to the percentages. Similarly, marketable tuber per cent by number and yield was calculated by excluding number and yield of small size tubers. All the treatments showed significant variation with respect to grades, seed tubers and marketable tubers (% by number and yield). Among ten treatments, maximum large grade tubers and marketable tubers were produced with treatment T9 (25% N of RDF as basal + 50% top dressing at 25 DAP + one foliar spray of urea @ 3% at 40 DAP). However, maximum seed tubers by number and yield was produced with treatment T5 (50% N of RDF as basal + 50% top dressing at 25 DAP + one foliar spray of urea @ 3% at 40 DAP).
