Abstract:
The experiment was conducted in the Horticulture Farm, Sher-e-Bangla
Agricultural University, Dhaka during November 2016 to March 2017. The
experiment consisted of two factors, such as Factor A: Potassium fertilizer
0
: 0 kg K

O/ha

: 75 kg K

O/ha, K
2
: 100 kg K
O/ha and
Factor B: Gibberellic acid-GA

0
: 0 ppm GA

: 80
ppm GA

: 100 ppm GA

: 120 ppm GA
. The two factorial experiment
was laid out in Randomized Complete Block Design with three replications.
Potassium and GA

influenced significantly on most of the studied parameters.
In case of potassium, the highest curd yield
and the lowest curd yield

performed the highest curd yield
. For combined effect, the highest curd yield (

. So, 100 kg potassium per hectare with 120 ppm GA
can be used for
broccoli production.
