Abstract:
The study was conducted at the Horticulture Farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka, Bangladesh during
the period from November 2006 to June 2007. The experiment consisted
with two factors. Factor A: Corm size (3 levels) such as: C
1
: Small size
corm (10-20 g): C
2
: Medium size corm (21-30 g) and C
3
: Large
size
corm
(3 1-40 g) and Factor B: Phosphorus (5 levels) as F
0
: 0 kg (Control); F,:
120 kg; P
2
: 130 kg; P
3
: 140 kg and P
4
: 150 kg 13
205
/ha, respectively. The
experiment was laid out in Randomized Complete Block l)esign (RCBD)
with three replications, in case of corm size, the highest yield of corni
(14.27 i/ha) and cormel (II
.30
tlha) was recorded from C
3
and the lowest
yield of corm (12.13 i/ha) and cormel (9.79 tlha) was from C
1
. In case of
phosphorus, the highest yield of corm (14.30 tlha) and cormel (11.62 i/ha)
was obtained from P
3
and the lowest yield of corm (11.46 ttha) and
For combind effect, the highest yield of
corm (15.34 i/ha) and cormel (12.44 tiha) was observed from C
cormel (9.24 i/ha) was from P
0
3?3
and
the lowest yield of corm (11.00 i/ha) and cormel (8.88 i/ha) was from
C3P0
, The highest benefit cost ratio (3.34) was attained from C
2 P3
and the
. It may be concluded that large
corm size with 140 kg
P2051ha
lowest (2.00) was recorded from C
3 P0
is best for growth, flowering and yield of
gladiolus.
