Abstract:
An experiment was conducted at the Horticulture Farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from May to December 2011 to
find the influence of spacing and gibberellic acid on growth and flowering of
tuberose . The experiment consisted of two factors. Three levels of spacing viz.,
1
: 20 × 10 cm ; (
viz.,
0
: 0 ppm
2
: 20 × 15 cm and (iii)
1
: 200 ppm
6
2
3
: 20 × 20 cm and four levels of GA
: 250 ppm and
respectively . The experiment was conducted in a Randomized Complete Block
Design with three replications. The maximum number of spike
and maximum number of spike
2
2
3
: 300 ppm GA
. In respect of combined effect, S
produced the maximum number of spike
2
G
3
. The maximum benefit cost ratio
and the minimum

G
0
.
Considering above findings the 20 cm × 20
cm spacing with 250 ppm GA

.
was suitable for tuberose cultivation
