Abstract:
An experiment was conducted to study the effect of plant spacing and nitrogen
on the growth and yield of okra at the central farm of Sher-e-Bangla
Agricultural University, Dhaka during the period from April to July 2007. The
experiment was laid out in Randomized Complete Block Design (RCBD) with
three replications, This experiment was conducted with two factors; Factor A:
Spacing (3 levels) i.e. S,=75 cm x 20 cm, S,75 cm x 40 cm, S
3 =75 cm x 60
cm and Factor B: Nitrogen (4 levels) i.e. N0=control. N
1=50 kg N/ha. N,=100
kg N/ha. N 3
=150 kg N/ha. In case of plant spacing, the highest yield (8.20 t/ha)
was recorded from the spacing S2
and the lowest yield (6.84 t/ha) was from S1 .
In case of nitrogen, the highest yield (8.25 t/ha) was obtained from N 3 and the
lowest yield (5.72 t/ha) was from N
o
. For combined eliect, the highest yield
(9.86 t/ha) was observed from the treatment combination of S2N 3
which was
similar (9.85 t/ha) to S2N2
. Though the highest yield was recorded from S
2N3
but on the basis of benefit cost ratio (8CR). the best (2.53) outcome was
obtained from the treatment combination of S
2N2. It may he concluded that
75cm x 40 cm spacing with 100 kg N/ha is the best for growth and yield of
okra.
