A field experiment was conducted during winter (rabi) season of 201314 at Ludhiana, Punjab, to determine the effect of four irrigation regimes (0, 2, 3 and 4 irrigations) and 6 levels of nutrient and hydrogel [100% recom- mended dose of fertilizer (RDF) 150 kg N: 60 kg P O : 30 kg K O/ha without hydrogel, 100% RDF with 2.5 kg/ha 2 5 2 hydrogel, 100% RDF with 5.0 kg/ha hydrogel, 75% RDF without hydrogel, 75% RDF with 2.5 kg/ha hydrogel and 75% RDF with 5.0 kg/ha hydrogel] on wheat [Triticum aestivum (L.) emend. Fiori & Paol.]. Grain yield was the highest under 4 irrigations which was, however, at par with grain yield under 3 irrigations. Using RDF H , 100 5 RDF H and RDF H , similar grain yield was recorded. Consumptive use was highest under 4 irrigations. Wa- 100 2.5 75 5 ter-use efficiency (WUE) decreased with increase in irrigation levels while it showed an increasing trend with in- crease in hydrogel dose. The highest WUE was found with no irrigations along RDF H which was statistically at 100 5 par with application of 2 irrigations along RDF H and no irrigation RDF H . 100 5 100 2.5References
