A field experiment was conducted during the summer seasons of 2015 and 2016 on loamy sand soils of Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat to assess the impact of irrigation, fertility and hydrogel levels on growth attributes, yield and economics of summer pearl millet [Pennisetum glaucum (L.) R. Br.]. The experiment was laid out in a split plot design with 3 replications, consisted of 3 irrigation levels [0.8, 1.0 and 1.2 irrigation water: cumulative pan evaporation ratio (IW: CPE)], 2 fertility levels (120: 60: 00 and 150: 75: 00 kg N: P₂O₅: K₂O/ha) in main plots and 3 hydrogel levels (0.0, 2.5 and 5.0 kg/ha) in sub-plots. The pooled results indicated that irrigation at 1.2 IW/CPE being at par with 1.0 IW/CPE enhanced growth parameters viz., plant height, number of effective and non-effective tillers, dry matter production, CGR and RGR and yield of pearl millet. Application of 150: 75: 00 kg N: P₂O_5: K₂O/ha (125% RDF) significantly improved growth parameters, seed yield, stover yield and harvest index over 100 % RDF (120: 60: 00 kg N: P₂O_5: K₂O/ha). Higher grain yield was a reflection of higher plant height, effective tillers/m, total dry-matter production, grain yield and stover yield of pearl millet under application of 5.0 kg hydrogel/ha. Significantly the highest net returns was obtained under higher levels of inputs viz., irrigation, nutrients and hydrogel.
