Abstract:
The study was conducted at the Farm of Sher-e-l3angla Agricultural University, Dhaka,
Bangladesh during the period from November, 2007 to June, 2008. The experiment consisted
with two factors. Factor A: Three levels of spacing: S: 15
x
10; S: 20
x
10 and
53:25
cm2
and Factor B: Five levels of potassium: K
0: 0kg (Control); K3 : 90kg; K2: 120 kg; K
3:
150 kg and K.
1: 180 kg K
2
0/ha, respectively. The experiment was laid out with Randomized
Complete Block Design with three replications. In case of spacing the highest flowering plant
(91.07%). thousand number of spike (761.48), number of cormel per plant (23.47), highest
yield of corm (17.08 Vha) and yield of cormel (13.83 tTha) were recorded from S2 while all
the above parameters were lowest at St. In case of potassium, the highest flowering plant
(94.00%), thousand number of spike (790.12), number of cormel per plant (23.43), highest
yield of corm (16.23 i.fha) and yield of connel (13.09 t/ha) were recorded from K
3
and lowest
from
Km For interaction effect the highest flowering plant (96.67%), thousand number of
spike (844.44), number of cormet per plant (25.60), highest yield of corm (18.66 tlha) and
yield of cormel (14.92 Vita) were recorded from S
1 K3
and the lowest from S3 K0
. The highest
benefit cost ratio (2.43) was obtained from S
2
K; and the lowest (1.31) from S;K0
. So, 20cm
10cm spacing with 150 kg K
2
0/ha were best for growth and flowering of gladiolus.
