Abstract:
The experiment was carried out in the experimental field of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka at the period of
March to July 2017 to find the growth and yield of okra as influenced by
different concentration of gibberellic acid. Seeds of BARI Dherosh 1 and
Hybrid Variety were used as planting materials. The experiment consisted
of two varieties of okra at levels of GA

. The two factorial experiment was laid out in Randomized
Complete Block Design (RCBD) with three replications. In case of variety,
the tallest plant 28.66, 82.48 and 128.95 cm, respectively was from V
1
variety at 20, 40 and 60 DAS, respectively. Variety V
2
performed the
maximum (18.38) number of pods and the highest pod yield (14.23 t ha
).
On the other hand, at 20 DAS, the tallest plant (31.13 cm) was observed
from G
3
(150 ppm GA
3
) and at 40 and 60 DAS, the tallest plant (90.76 and
135.1 cm, respectively) was observed from G

(100 ppm GA

)
was contributed by G
2
maximum (19.52) number of pods and the highest pod yield (16.18 t ha
. In The highest pod yield 14.23(t ha

) was recorded
from the application of 100ppm of GA

in Hybrid Variety followed by the
yield of BARI Dherosh 1 14.01(t ha

) with 100ppm of GA

at optimum
harvest date. Both varieties increased the yield of okra at 100ppm. So,
100ppm GA

is suitable for okra production.
