The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during April to August 2015. BARI Dherosh-1 was used in this experiment. The experiment consisted of two factors viz., Potassium fertilizer as K0: 0 kg K2O/ha (control), K1: 60 kg K2O/ha, K2: 90 kgK2O/ha and K3: 120 kg K2O/ha; and Gibberellic acid (3 levels) as G0: 0 ppm GA3 (control) G1: 60 ppm GA3, G2: 90 ppm GA3 respectively. The experiment was laid out in Randomized Complete Block Design with three replications. All the parameters were significantly influenced by different levels of potassium and gibberellic acid. Due to the effect of potassium, the highest yield (19.04 t/ha) was observed from K3 and the lowest yield (12.11 t/ha) from K0. In case of Gibberellic acid, the highest yield (17.08t/ha) was found from G2 and the lowest yield (16.01 t/ha) from G0. From growth, yield and economic point of view, it is apparent that the application of 120 kg K2O/ha with 90 ppm GA3 was the best for growth and yield of okra.
