A field experiment was conducted in split-plot design during the winter (rabi) season of 2015–16 at Agronomy Research Farm, Kumarganj, Ayodhya (Uttar Pradesh) to evaluate the response of potato (Solanum tubersum L.) to irrigation methods, moisture regimes and nitrogen management. Treatments effect was non-significant on initial plant stand [15 days after planting (DAP)]. The plant height, number of haulms, number of leaves at 90 DAP and dry weight of haulms were significantly superior under regular furrow irrigation method, 1.0 irrigation water: cumulative pan evaporation (IW: CPE) and 75% dose of urea through N + 25% dose of N through FYM over their counterparts. All the growth characters were found highest under nitrogen-management treatment 75% dose of urea through N + 25% dose of N through FYM, which was statistically superior to rest of the nitrogen-management treatments. Yield attributes, viz. number of tubers (grade-wise)/hill, weight of tubers (grade-wise) (kg/plot), and tuber yield (q/ha) were found highest under regular furrow method of irrigation (M1 ) and moisture regime, 1.0 IW: CPE (I2 ) over 0.8 IW: CPE (I1 ) and 1.2 IW: CPE (I3 ). Moisture regimes significantly influenced number of all grade of tubers. All the yield attributes were significantly higher under nitrogen management treatment N2, and was statistically superior to rest of the nitrogen management treatments. © 2021, Indian Society of Agronomy.
