Abstract:
A field experiment was conducted to determine the effect of vermicompost and
gibberellin on bitter gourd production in the water surface of fish pond during March
to June 2019 at the Horticulture farm of Sher-e-Bangla Agricultural University,
Dhaka. The experiment was considered of two factors. Factor A: vermicompost (3
levels) viz. (i) 90% coco peat + 10% broken bricks (V
), (ii) 30% vermicompost +
60% coco peat/pot + 10% broken bricks (V
1
viii
0
) and (iii) 60% vermicompost + 30% coco
peat/pot + 10% broken bricks (V
(Control) (G
0
) and (ii) 40 ppm GA
2
) and Factor B: GA
3
(G
1
3
(2 levels) viz. (i) 0 ppm GA
). It was laid out in the two factors completely
randomized design (CRD) with three replications. Regarding vermicompost, V
showed higher growth and yield and resulted highest fruit yield (21.58 t ha
)
compared to control (11.97 t ha
-1
). In terms of GA
application, the highest fruit yield
(19.35 t ha
-1
) was found from G
1
(40 ppm GA
3
3
) whereas the lowest (14.62 t ha
) was
from control treatment G
0
(0 ppm GA
3
). Considering interaction effect, V
showed
highest fruit weight pot
-1
(1783 g) and fruit yield (24.76 t ha
) whereas the lowest
fruit weight pot
-1
(945.60 g) and fruit yield (10.80 t ha
-1
-1
2
) were obtained from V
. It
can be concluded that vermicompost with GA3 application was effective for better
gourd cultivation in floating agriculture.
