A field experiment was carried out during Rabi season of 2018-19 and 2019-20 at research farm of R.K.(P.G.) College, Shamli, under split-split plot design with three replications. Treatment consisted irrigation at four physiological stages and at six physiological stages as main plot, seed rates (100,120 and 140 kg seed/ha) as sub plot and fertility levels (F1: 100kg N : 50kg P2O5 : 40kg K2O, F2: 125kg N : 62.5kg P2O5 : 40kg K2O and F3: 150kg N : 75kg P2O5 : 40kg K2O ) as sub-sub plot. Irrigation at six physiological stages resulted significantly higher grain yield (5.25 t/ha), harvest index (0.46), effective tillers /m2(426.09), spike length (11.4 cm), spikelets per spike (19.6), grain per spike (53.9), grain weight per spike (2.3 g) and 1000 grain weight (44.6) and resulted 16.41% higher grain, 5.21% straw and 10.45% biological yield over four irrigations. Seed rates of 100 kg/ha resulted 8.10 percent higher grain yield over 140 kg seed/ha. Whereas, application of 125kg N : 62.5kg P2O5 : 40kg K2O/ha resulted 13.51%, 17.64% and 15.70% higher grain, straw and biological yield, respectively over 100kg N : 50kg P2O5 : 40kg K2O/ha. Plants nurtured with 150kg N: 75kg P2O5 and 40kg K2O, maintained higher leaf area and total chlorophyll in their leaves. Irrigation at six physiological stages resulted 33.22% higher net return over four irrigations whereas, application of 125kg N: 62.5kg P2O5:40kg K2O/ha resulted 4% higher net return over 100kg N: 50kg P2O5: 40kg K2O/ha
