Abstract:
The experiment was conducted at the Horticultural Farm, Sher-e-Bangla
Agricultural University, Dhaka, during the period from March 2012 to May
2012. The experiment consisted with two factors, such as factor-A: three
levels of plant spacing; S
three levels of phosphorus; P
1
: 35×20 cm, S
o
: 0 kg, P
2
: 35×25 cm and S
1
: 50 kg and P
2
3
: 35×30 cm and
: 100 kg P
/ha
respectively. The experiment was set up in a Randomized Completely Block
Design with three replications. Spacing and phosphorus fertilizer
significantly influence on most of the parameters. In case of spacing, highest
number of spike (126,582/ha) was obtained from S
and the lowest
(25,316/ha) from S

. For phosphorus, highest number of spike (101,265/ha)
was obtained from P
1
and the lowest (20,320/ha) from P
. For combined
effect, highest number of spike (132,531/ha) was obtained from S
o
and the
lowest (27,260/ha) from S

treatment. So, 35×25 cm spacing with 50 kg
