Abstract:
The experiment was conducted in the Horticultural Farm of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh to determine the response of bell
pepper varieties to plant growth regulators. The experiment consisted of two
factors: Factor A: Bell pepper (two varieties) V
: BARI Misti Morich-1 and
V
G
2
0
1
: Exotic variety (Lamuyo); Factor B: Plant growth regulators (four levels) as
: No plant growth regulator (water), G
1
: Gibberellic Acid (GA
) @ 100 ppm,
G
2
: 4-Chloro Phenoxy Acetic Acid (4-CPA) @ 2000 ppm and G
: Litosen @
1000 ppm. The experiment was laid out in a Randomized Complete Block Design
with three replications. In case of bell pepper varieties, the maximum yield (22.47
t/ha) was attained from V
2
, while the minimum yield (20.09 t/ha) from V
. For
plant growth regulators, the highest yield (25.17 t/ha) was recorded from G
,
whereas the lowest (15.33 t/ha) from G
. Due to the interaction effect of variety
and plant growth regulators, the highest yield (26.52 t/ha) was found from V
0
,
while the lowest yield (14.51 t/ha) from V
1
G
0
. So, V
2
G
(combination with
Lamuyo and 4-CPA) was found best for growth and yield of bell pepper.
