Abstract:
The experiment was conducted in the Horticulture Farm and laboratory of
Sher-e-Bangla Agricultural University, Dhaka during October 2016 to February
2017. The experiment consisted of two factors: Factor A: Pinching method
0
: No pinching
: Pinching apical meristem at 15 days
after transplanting
2
1
ii
3
: Pinching apical meristem at 30 DAT and P
:
Pinching axillary buds at 45 DAT; and Factor B: Gibberellic acid-GA
0
: 0 ppm
1
: 50 ppm and G
2
:100 ppm GA
. The two factor
experiment was laid out in Randomized Complete Block Design with three
replications. Pinching methods and gibberellic acid influenced significantly on
most of the parameters. In case of pinching, the highest curd yield
1
and the lowest curd yield
3
. For gibberellic
acid, G
1
0
performed the highest curd yield
. For combined effect, the highest curd yield
0
1
G
1
and the lowest curd yield
. The highest
benefit cost ratio
1
G
0
and the lowest
benefit cost ratio (1.09
0
G
. So, pinching apical meristem at 15 DAT with
50 ppm GA
3
0
can be used for commercial broccoli production.
