Abstract:
The experiment was conducted in the Horticultural Farm of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh. The experiment consisted of two
factors. Factor A: Plant growth regulators (four levels) as G
Gibberellic Acid (GA
3
) @ 30 ppm, G
: 4-Chloro Phenoxy Acetic Acid (4-CPA)
@ 45 ppm and G
3
ii
2
: 4-Chloro Phenoxy Acetic Acid (4-CPA) @ 45 ppm +
Gibberellic Acid (GA
) @ 30 ppm and Factor B: Number of spray (three levels)
as N
0
3
: Control (no spray), N
1
: Two spray, N
Three spray. The experiment was
laid out in a Randomized Complete Block Design with three replications. In case
of plant growth regulators, the highest yield (27.77 t/ha) was found from G
treatment, whereas the lowest (18.87 t/ha) from G
2:
treatment. For number of spray
the maximum yield (26.0 t/ha) was recorded from N
0
treatment, while the
minimum yield (19.87 t/ha) from N
0
2
treatment. Due to combined effect, the
highest yield (31.8 t/ha) with net income (1416558) and BCR (2.46) was observed
from G
3
N
treatment combination, while the lowest yield (17.5 t/ha) with net
income (433045) and BCR (1.49) from G
2
0
N
treatment combination. So,
economic analysis revealed that the G
3
N
2
0
treatment combination appeared to be
the best for achieving the higher growth, yield and economic benefit of sweet
pepper.
