Abstract:
A field experiment was conducted to evaluate the effect of plant growth regulators for
flowering, fruit setting and yield of bitter gourd during February to June 2016 at Shere-Bangla
Agricultural University, Dhaka. The experiment was consisted of two
factors. Factor A: Four levels of plant growth regulators: PGR
PGR
2
- NAA and PGR
3
ii
0
- control, PGR
- MH and Factor B: Three levels of application stages: S
-seed
soaking, S
2
- 4-leaf stage and S
- flower budding stage, respectively. The experiment
was laid out in Randomized Complete Block Design with four replications. Plant
growth regulators and various application stages showed significant variations with
most of the parameters. In case of plant growth regulators, the highest number of
branch plant
-1
3
-1
-1
and the lowest from
PGR
0
3
. For various application stages, the highest number of branch plant
-1
2
and the lowest from S
. For combined effect the highest number of
branch plant
-1

-1

S
and the lowest from
PGR

. So the use of maleic hydrazide @ 100 ppm at 4-leaf stage would be the best
option in growth, sex expression and yield of bitter gourd.
