Abstract:
A field experiment was conducted at the Floriculture Research Field, Bangladesh
Agricultural Research Institute, Gazipur from February 2013 to November 2013. The
experiment consisted of two factors such as Factor A: bulb size (3 levels): S
(1.0-1.5cm)
,
S
2:
medium (>1.5-2.0 cm) and S
large (>2.0-2.5 cm) and Factor B: Four
levels of boron, B
0
: Control, B
1
: 1kg/ha, B
2
3:
: 2 kg/ha and
B
: 3 kg/ha
. The experiment
was laid out in Randomized Complete Block Design with three replications. The
results of the experiment showed that the bulb size significantly influenced the time
taken for emergence, spike initiation, flowering, spike length, rachis length, flower
durability, leaves/plant, florets/spike, spikes/ha and bulbs/ha.Large bulb produced
flower earlier than small bulb and better quality spikes. The highest yield of spikes
(3,40,000 no./ha) and bulb ( 9.0 t/ha) were also produced form S

All doses of boron
significantly improve on the yield contributing characters of tuberose over control,
while the most effective dose was B

However, the treatment combination of large
size bulb with 2 kg/ha boron contributed the best performance in respect of vegetative
growth, flower and bulb production in tuberose.
