Abstract:
The experiment was conducted in Horticulture Farm, Sher-e-I3angla .Agricultural University,
Dhaka, during October 2007 to February 2008 to find out the effect of plant spacing and
potassium on growth and yield of cabbage. The experiment consisted of Factor A: three plant
spacing; S
1
: 60 cm
x
30 cm,
$2:
60 cm
x
40 cm and S
3: 60 cm
x
60 cm and Factor B: four
levels of potassium fertilizer; !K: 0 kg;
K;: 90
kg;
K 2
: 120 kg and K3:
150 kg K20/ha
respectively. The experiment was conducted in Randomized Complete Block Design
(RCBD) with three replication. Different treatments showed sigiificant variations on growth,
yield components and yield of cabbage. Highest plant height at 60 DAT (37.70cm),
maximum diameter of head (19.05 cm) and fresh weight of head (187kg) were found from
and lowest was observed from
Si.
On the other hand, the tallest plant height at 60 DAT
cm), maximum diameter of head (18.81 cm) and fresh weight of head (1.62 kg) were
found from K3 and lowest was observed from K
0
treatment. For combined effect the highest
plant height at 60 DAT (40.23 cm), maximum diameter of head (21.02 cm), highest fresh
weight of head (2.21 kg) were found from S
(39.51
and lowest was observed from SilCo
treatment. The highest gross yield (81.89 t/ha), marketable yield (61.30 t/ha) and benefit cost
3K3
ratio (1.98) was noted from S
2K3
and lowest from S
1K0
. So, 60 cm
x
40cm spacing with
150
kg K
2
0fha was best for growth and yield of cabbage.
