Abstract: The experiment entitled Effect of moisture regimes and integrated nitrogen management on the yield of potato (Solanum tuberosum L.) was conducted during 2017-18 at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya (U.P.). The treatments included two irrigation methods ie M₁ (Regular furrow irrigation method) and M₂ (alternate furrow irrigation method), three moisture regimes ie I₁ 0.8 IW/CPE, I₂ 1.0 IW/CPE and I₃1.2 IW/CPE with 6cm water depth and three nitrogen management ie N₁ (100% N through Urea), N₂ (75% N through Urea +25% N through compost) and N₃ (50% N through compost. Regular furrow irrigation M₁ with 1.0IW/CPE (I₂) and integrated nitrogen management 75% N through urea + 25% N through compost was found better for potato yield performance. Treatment combination M₁I₂N₂ given the highest net return of T 126255 ha^-1 with B-C ratio of 1.92 during investigation.
