Abstract

A experiment was conducted during rabi season of 2021-22 at CSAUA&T, Kanpur, Students’ Instructional Farm to see the effect of plant growth promoters (GA₃, Nitrobenzene Seaweed extract solid & liquid) and micronutrients(Zn, Fe, Mn, Cu) on performance of wheat varieties. The experiment was conducted in split plot design with three replications. The result reported that the variety, DBW-187 and K-1006 exhibited significantly (P≤0.05) higher growth and yield (10.89% and 2.41%). Among PGPs, applied micronutrients (Zn, Fe, B, Cu) @ 0.5% resulted statistically (P≤0.05) higher dry weight, number of productive tillers (448.4m^-2), grain yield (4.81 t/ha), biological yield (11.93 t/ha) and harvest index (41%). Additionally, the grain yield was increased by 16.17%, 12.24%, 9.55%, 7.70%, and 4.40% with micronutrients (Zn, Fe, B and Cu), Gibberellic acid, Seaweed extract liquid, Seaweed extract granules, and nitrobenzene respectively, as compared to the control (without PGPs).
