Abstract:
A study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural
University, to find out the effect of foliar application of different levels of
gibberellic acid and zinc on growth and yield of cabbage. The experiment
consisted of two factors such as: Factor A: three levels of gibberellic acid viz., G
:
control, G
1
: 100 ppm, G
2
: 150 ppm GA
3
and Factor B: three levels of zinc viz., Z
:
control, Z
1
: 50 ppm, Z
: 100 ppm Zn. The experiment was laid out in Randomized
Complete Block Design with three replications. In case of different levels of GA
2
,
the highest head diameter (22.56 cm), head thickness (14.88 cm), fresh weight of
head (1.96 kg), dry matter of head (6.33 %), yield (81.68 t/ha) were found from G
while the lowest head diameter (19.28 cm), head thickness (12.32 cm), fresh
weight of head (1.50 kg), dry matter of head (5.45 %), yield (62.50 t/ha) from G
.
For different levels of zinc, the highest head diameter (22.42 cm), head thickness
(14.87 cm), fresh weight of head (1.89 kg), dry matter of head (6.13 %), yield
(78.75 t/ha) were recorded from Z
whereas the lowest head diameter (19.39 cm),
head thickness (12.36 cm), fresh weight of head (1.57 kg), dry matter of head
(5.53 %), yield (65.55 t/ha) from Z
2
. Due to interaction effect, the highest head
diameter (23.07 cm), head thickness (15.33 cm), fresh weight of head (2.13 kg),
dry matter of head (6.66 %), yield (88.75 t/ha) were recorded from G
0
where as
the lowest head diameter (18.50 cm), head thickness (12.00 cm), fresh weight of
head (1.23 kg), dry matter of head (5.00 %), yield (51.25 t/ha) from G
. The
highest benefit cost ratio (2.57) was noted from the combination of G
and the
lowest (1.57) from G
0
Z
From growth, yield and economic point of view, it is
apparent that the combination of 150 ppm GA
0.
with 100 ppm Zn was suitable for
cabbage.
