Evaluation of irrigation methods, moisture regimes and integrated nitrogen management in potato (Solanum tuberosum L.)

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.
