Abstract
The experiment was conducted at the Horticultural farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka, during the period from
April, 2009 to March, 2010 to investigate the effect phosphorus and potassium on
growth, flowering and bulb yield of tuberose. The experiment consisted of two
factors. Factor A: Four levels of phosphorus i.e. P

O/ha respectively. The experiment was laid out with Randomized
Complete Block Design with three replications. In case of Phosphorus, the highest
flower (19.25 t/ha) and bulb (24.66 t/ha) yield was recorded from P
and the
lowest flower (9.60 t/ha) and bulb (14.51 t/ha) yield was recorded from P
In case
of Potassium, the highest flower (16.39 t/ha) and bulb (21.99 t/ha) yield was noted
from K
and the lowest flower (11.48 t/ha) and bulb (17.17 t/ha) yield was
recorded from K

For combined effect the highest flower (22.27 t/ha) and bulb
(27.57 t/ha) yield was noted from P
