The investigation entitled “Effect of different method of irrigation and for levels of drip with suitable nitrogen doses on yield and its attributes on potato (Solanum tuberosum L.)” has been carried out at Research Cum Instructional Farm, College of Agriculture, IGKV, Raipur (C.G.) during rabi season 2022-23 and 2023-24. This experiment was laid out in split plot design with three replications, keeping five irrigation levels i.e. I₁: 75% CPE with drip, I₂: 100% CPE with drip, I₃: 125% CPE with drip, I₄: 150% CPE with drip and I₅: Furrow irrigation as a main plot and four nitrogen doses i.e. N₁: 90 kg N ha^-1, N₂: 120 kg N ha^-1, N₃: 150 kg N ha^-1 and N₄: 180 kg N ha^-1 as sub plot. The yield parameters recorded significantly higher under I₄N₄ (100% CPE with drip + 180 kg N ha^-1) viz. number of tubers plant^-1 (12.67), weight of tubers plant^-1 (350.58 g), marketable tuber yield (26.46 kg plot^-1) and total tuber yield (35.41 t ha^-1). However, higher unmarketable tuber yield was obtained with treatment I₃N₄ (125% CPE with drip + 180 kg N ha^-1) of (9.61 kg plot^-1). While minimum was recorded under combination of furrow irrigation and lowest dose of nitrogen.
