Abstract:
A field experiment was conducted in split-plot design during the (rabi) 2015-16 at Agronomy Research Farm, ANDUAT, Kumarganj, Ayodhya (U.P.) to evaluate the response of potato to irrigation methods, moisture regimes and nitrogen management. The growth characters viz. plant height, number of haulms, number of leaves at 60 DAP and fresh weight of haulms (dehaulming stage) were significantly superior under regular furrow irrigation method, 1.0 IW/CPE and 75% dose of urea through N+25% dose of N through FYM over their counterparts. In case of nitrogen management all the growth characters were recorded highest under nitrogen management treatment 75% dose of urea through N + 25% dose of N through FYM, which was statistically superior over rest of nitrogen management treatments. Yield attributes viz., Number of superior grade tubers (>75g)/hill, weight of superior grade tubers (>75g) 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). Number of all grade of tubers was found to be significant due to effect of moisture regimes. In nitrogen management all the yield attributes were recorded significantly higher under nitrogen management treatment (N2), which was statistically superior over rest of the nitrogen management treatments. Quality parameters viz., dry matter (%) and starch content in tuber (%) was found highest under regular furrow method of irrigation (M1) and moisture regime, 1.0 IW/CPE (I2) and nitrogen management treatment (N2). The highest Net return (Rs/ha) and B:C ratio was recorded with regular furrow method (M1) in combination with I2 (1.0 IW/CPE ratio) and N2 nitrogen management practice (75% dose of N through Urea+25% N through FYM) followed by M1I2 N2 and M2I2N2 respectively.
