Abstract:
The study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka to find out response of gibberellic acid and potash nutrient on
growth and yield of late planting cabbage. The experiment consisted of two
factors: Factor A: Gibberellic acid (four levels) as- G
0
: 0, G
1
: 90, G
: 150
ppm GA
K
2
3
and Factor B: Potassium fertilizer (three levels) as- K
: 200 kg K
2
0
2
: 120, G
: 0, K
O. The two factors experiment was laid out in Randomized
Complete Block Design with three replications. In case of different growth
regulators, the highest marketable yield (65.1 t/ha) were found from G
, while the
lowest marketable yield (40.4 t/ha) from G
. For different levels of potassium
fertilizer, the highest marketable yield (64.4 t/ha) were recorded from K
0
, whereas
the lowest marketable yield (44.6 t/ha) from K
. Due to interaction effect, the
highest marketable yield (75.6 t/ha) were recorded from G
0
2
K
, whereas the lowest
marketable yield (38.4 t/ha) from G
0
K
0
1
. The highest benefit cost ratio (2.31) was
noted from the combination of G
2
K
1
and the lowest (1.24) from G
. From
growth, yield and also economic point of view, it is apparent that the combination
of G
2
K
1
was suitable for late planting cabbage cultivation.
