Abstract

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, from November 2019 to March 2020 to assess the combined effects of sowing date and plant growth regulators (PGRs) on the growth and yield of wheat cv BARI Gom-33. The experiment was conducted in a split-plot design with three replications, with sowing dates in the main plots and PGRs in the sub-plots, totaling 36 plots (12 treatments × 3 replications). Results of the study revealed that sowing on 5th December with Gibberellic Acid (GA3) application increased grain yield by 25.62% over the control. This sowing date also produced 7.59% and 12.83% higher yields than early and late sowing dates, respectively. The results suggest that sowing on 5th December combined with GA3 application effectively optimizes wheat growth and yield, providing a promising approach for enhancing wheat production and supporting sustainable agriculture.
