Abstract: The field experiment was undertaken at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during kharif and rabi season of 2016-17 and 2017-18 to evaluate the effect of summer green manuring with adoption of different tillage practices on growth indices of wheat crops under irrigated condition of Eastern Uttar Pradesh. The field experiment was laid-out in split plot design with three replications. The treatment comprised of four tillage practices in main plot viz., T₁ (CTM-CTW), T₂ (MTM-MTW), T₃ (MTM-ZTW), T₄ (ZTM-ZTW) and five summer green manuring in sub plot viz., M₁ (summer fallowing), M₂ (Dhaincha (Sesbania aculeata), M₃ -Sunnhemp (Crotalaria juncea), M₄ (Clusterbean (Cyamopsis tetragonoloba), M₅- Cowpea (Vigna sinensis) were investigated. The result revealed that the crop growth rate of wheat was significantly influenced by tillage practices and summer green manuring during both the years. However, relative growth rate was not significantly affected during both the years of investigation. Among the tillage practices the significantly highest crop growth rate (g/m²/day) was recorded in T₄-ZTM- ZTW (0.389, 0.398, 0.925, 0.962, 4.714, 4.704, 1.914, 1.967 at 30, 60, 90 DAS and at harvest, respectively in both years) at all the stage of observation during both the years but it was found statistically at par with T₁-(CTM-CTW). Among the summer green manuring practices, crop growth rate was significantly highest in M₂ -Dhaincha (Sesbania aculeata) (0.389, 0.397, 0.921, 0.952, 4.728, 4.701, 1.943, 2.016 at 30, 60, 90 DAS and at harvest, respectively in both years) but it was statistically at par with M₃-Sunnhemp (Crotalaria juncea) at all the growth stages of wheat during both the years. In conclusion, zero tillage wheat with dhaincha or sunhemp was the best practice for the cultivation of wheat under irrigated conditions of Eastern Uttar Pradesh.
