Abstract:
The experiment was conducted at the experimental field of Sher-e-Bangla
Agricultural University, Dhaka during the rabi season from November 2016 to
February 2017 to investigate the yield performance of mustard following the
application of GA
3
. The treatment consisted of two factors, application time of
GA
3
viz. S
1
= vegetative stage and S
2
= flowering stage; and six different levels
of GA
3
viz. G
0
= 0 ppm, G
20
= 20 ppm, G
40
=40 ppm, G
60
=60 ppm, G
80
=80
ppm, and G
100
=100 ppm. The experiment was laid out in Randomized
Complete Block Design (factorial) with three replications. Results showed a
significant variation among the treatments in respect of most of the parameters
studied. The maximum length of silique (over 5 cm), number siliquae per plant
(over 55), number of seeds per siliquae (over 31) and 1000 seed weight (over 3
g) were shown by 60-80 ppm GA
3
application of GA
3
. Accordingly, the
maximum yield of seeds per hectare (0.69-0.90 t) was obtained from 60-80
ppm
application of GA
3
at both the stages. The lowest seed yield per hectare
(0.44 tones) was obtained from the fields wherein no GA
3
was applied.
