Abstract:
An experiment was conducted at the Horticulture farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from November 2013 to April
2014 to study the growth and yield of tomato as influenced by plant growth
regulators. The experiment was laid out in a Randomized Complete Block
Design with three replications and consisted of two factors, Factor A (3 Levels
of IAA): I
0
= Control, I
1
= 25 ppm, I
= 35 ppm IAA and Factor B (4 Levels of
GA
3
): G
0
= Control, G
1
respectively. In case of IAA, I
2
= 30 ppm, G
2
ii
2
= 60 ppm
and G
3
= 90 ppm GA
treatment produced the highest yield (74.76
t/ha) and I
0
produced the lowest yield (58.69 t/ha). In case of GA
produced
the highest yield (76.45 t/ha) and G
produced the lowest yield (53.30 t/ha).
The treatment combination of I
2
G
2
0
produced the highest yield (85.42 t/ha) and
I
0
G
produced the lowest yield (47.25 t/ha). The highest (3.58) benefit cost ratio
was recorded from I
0
2
G
2
. So, 35 ppm IAA with 60 ppm GA
was found suitable
for growth and yield of tomato.
