Abstract:
An experiment was conducted during the period of April to June 2021 at Horticulture farm of Shere-Bangla
Agricultural
University,
Dhaka
1207,
Bangladesh
to
evaluate
the
effect
of
stem
pruning
and
foliar
application
of
gibberellic
acid
(GA
3
) and cytokinin on growth and yield of cucumber.
The experiment was laid out in the Randomized Complete Block Design with four replications.
Treatment as four levels of gibberellic acid (GA
3
) and cytokinin application i.e., T
0
=
50 ppm GA
3
spray, T
2
= 2.5 ppm cytokinin spray, T
3
= 50 ppm GA
3
and 2.5 ppm cytokinin spray;
and three levels of stem pruning i.e., P
0
= No pruning, P
1
=No spray, T
1
= Pruning to two primary branches, P
2
=
Pruning to three primary branches which in combination made 12 treatment combination.
Application of GA
3
and cytokinin resulted the highest vine length (27.13 cm at 25 DAS and 74.00
cm at 35 DAS), number of leaves (12.33 at 25 DAS and 34.50 at 45 DAS), number of fruits (15.08
plant
-1
), individual fruit weight (242.99 g), fruit yield (23.05 t ha
-1
) from T
3
treatment. In case of
pruning, the highest vine length (73.34 cm at 35 DAS), number of leaves (39.31 plant
at 45 DAS),
number of fruits (14.75 plant
-1
), individual fruit weight (266.17 g), fruit yield (23.07 t ha
) from
P
2
treatment. The combined effect of P
2
T
3
gave the best result for all vegetative and reproductive
growth and development i.e., vine length (100.75 cm), total number of fruits (17.88) and fruit yield
(34.68 t ha
-1
). So, the combination of P
2
T
3
found the best to cultivate cucumber.
