A field experiment was conducted during the Rabi seasons of 2021-22 and 2022-23 at Agricultural Research Farm, Department of Agronomy, Raja Balwant Singh College, Bichpuri (Agra). The variables involved in this study were Irrigation scheduling (Main plot) viz., control (No irrigation, I0), Active tillering at 30-35 DAS (I1) and Active tillering at 30-35 DAS, flag leaf at 60-65 DAS and milking at 80-85 DAS (I2) along with Nitrogen levels (Sub plot) viz., 75% RDN (45 kg N )+ 30 kg P2O5 + 20 kg K2O) (N1) and 100% RDN (60 kg N) + 30 kg P2O5 + 20 kg K2O) (N2); C. Hydrogel levels (Sub-sub plot) viz., control (No hydrogel, H0), Pusa Hydrogel @ 2.5 kg ha-1 (H1), Pusa Hydrogel @ 5.0 kg ha-1 (H2) and Pusa Hydrogel @ 7.5 kg ha-1 (H3). Thus, all factors were compared in a split plot design with three replications. Results revealed that the application of Pusa Hydrogel @ 7.5 kg ha⁻¹ (H₃) significantly enhanced water-related parameters of barley crop. The treatment recorded the highest soil moisture content (20.85–20.88%), soil moisture extraction (13.60–13.64%), water use efficiency (16.21–16.26 kg ha⁻¹ mm), consumptive use of water (30.12–30.18 cm), and relative water content (73.80–73.98%), while the lowest values for all these parameters were observed under the control (no hydrogel).
