Abstract
An experiment was conducted at CRF (Crop Research Farm), Department of Agronomy, SHUATS, Prayagraj, (U.P.) during Zaid crop season 2020. The soil of site was sandy loam in texture with neutral PH. The experiment was carried out in split plot design having nine treatment consisted of main plot Irrigation viz., I1 (2 Irrigation during Emergence and Early Tillering), I2 (3 Irrigation during Emergence, Early Tillering and Boot stage) and I3 (4 Irrigation during Emergence, Early Tillering, Boot stage and Grain filling) and sub plot, Hydrogel viz., H0 (0 kg/ha), H1 (2 kg/ha) and H2 (4 kg/ha) which are replicated thrice and effect was observed on Manipuri variety of Bajra. The result indicated that increase in irrigation interval and hydrogel significantly improved yield attributes and yield. At, harvesting, 4 irrigation recorded maximum of Grain yield (1.88 t/ha), Stover yield (4.31 t/ha) and Harvest index (30.24 %) hydrogel also resulted significantly higher Grain yield (1.98 t/ha), Stover yield (4.44 t/ha) and Harvest index (30.79 %) Maximum Gross return (69222.96/ha), Net return (45066.76/ha) and Benefit to Cost ratio (2.87) were recorded by application of 4 kg/ha hydrogel with 4 irrigation.
