Abstract:
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 K

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
and the lowest yield
0
. In case of Gibberellic acid, the highest yield
and the lowest yield

. From growth,
yield and economic point of view, it is apparent that the application of 120 kg K

O/ha with 90 ppm GA
was the best for
growth and yield of okra.
