Abstract: An experiment was conducted at experimental field of Sher-e-Bangla Agricultural University, Bangladesh to find out the growth and yield performance of wheat to gibberellic acid concentrations. Experiment consisted foliar application of three concentrations of GA3 viz. G0: No GA3 i.e., control condition; G1: 100 ppm GA3 and G2: 200 ppm GA3. Maximum plant height (89.9 cm), number of tiller plant (5.0), CGR (5.8), RGR (0.04), dry matter content plant (26.8 g), number of spikes plant (4.1), number of spikelets spike (19.0), ear length (17.0 cm), filled grains spike (30.4), total grains spike (32.6), weight of 1000-grains (45.5 g), grain yield (3.9 tha-1), straw yield (4.6 tha-1), biological yield (8.5 tha-1) and harvest index (46.1 ) were found from G2 whereas minimum from G0.
