Abstract
The field experiment entitled “Productivity of wheat (Triticum aestivum L.) in relation to hydrogel as influenced by different irrigation regimes and nutrient levels” was conducted at the Research Farm of the Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana during rabi 2013-14. The soil of the experimental field was loamy sand, slightly alkaline in reaction, low in available nitrogen and medium in phosphorus and potassium. The experiment was conducted in split plot design with 24 treatments viz. four irrigation levels in main plots and six levels of nutrient and hydrogel doses in sub plots with three replications. Increase in the irrigation frequency significantly increased the dry matter accumulation and leaf area index at 120 DAS. Significantly higher plant height, tiller density and effective tillers were recorded with four irrigations as compared to no and two irrigations and were statistically at par with three irrigations. The highest tiller count was recorded under three irrigations which was statistically at par with four irrigations. The highest biological yield was recorded with four irrigations and was significantly better than three, two and no irrigations. Grain yield recorded was highest under four irrigations and was statistically at par with grain yield under three irrigations. The higher yield attributes (viz. tiller density and effective tillers), dry matter accumulation, biological and grain yield were recorded under 100% RDF with 5.0 kg/ha hydrogel (RDF100H5) which was statistically at par with 100% RDF with 2.5 kg/ha hydrogel (RDF100H2.5) and 75% RDF with 5 kg/ha hydrogel (RDF75H5). Application of hydrogel improved the nutrient uptake by the crop. The highest leaf area and plant height were recorded with RDF75H5 which were at par with 100% RDF with 2.5 kg/ha hydrogel RDF100H5 and RDF100H2.5.
