Abstract:
An experiment was conducted to evaluate the response of different levels of
naphthalene acetic acid and phosphorus on growth and yield of okra, at
Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during the
period from March to July, 2015. BARI Dherosh-1 was used as test crop in this
experiment. The experiment consisted of two factors viz., Naphthalene Acetic
Acid (4 levels) as N
0
: 0 ppm, N
1
: 50 ppm, N
2
: 100 ppm and N
: 150 ppm NAA;
and Phosphorus fertilizer (3 levels) as P
0
: 0 kg P

and P

respectively. The experiment was laid out in
Randomized Complete Block Design with three replications. Due to the effect
of naphthalene acetic acid, the highest yield (15.31 t/ha) was recorded from N
and the lowest yield (9.51 t/ha) from N
. In case of phosphorus, the highest
yield (14.20 t/ha) was found from P
2
0
and the lowest yield (12.12 t/ha) from P
.
For combined effect, the highest yield (16.25t/ha) was found from N
and the
lowest yield from N
0
P
0
(8.54 t/ha). So, 100 ppm NAA and 70 kg P
was
best for growth and yield of okra.
