Abstract:
The experiment was carried out at the Horticultue farm of Sher-e-Bangla Agricultural
University during the period of march to July, 2018. The experiment was carried out
to evaluate the response of seed priming and vermicompost on germination, growth
and yield of okra .The experiment consists of two factors such as three levels of seed
priming treatments viz, P
0
No priming (with water), P
ii
1
(Halopriming; CaCl
- 1 ppm)
and P
2
(Osmopriming; MgSO
4
- 3 ppm) and four levels of vermicompost viz, V
(control; no
vermicompost), V
1
(5 t ha
-1
vermicompost), V
2
(7.5 t ha
-1
vermicompost)
and V
3
(10 t ha
-1
vermicompost) was laid out in Randomized Complete Block Design
with the three replications. Results showed that the highest percent of (%) seed
germination (95.75%) was found from P
2
V
whereas the lowest percent of (%) seed
germination (73.00%) was found in P
0
V
0
3
. Regarding growth parameters, the highest
plant height (152.40 cm) and number of leaves plant
-1
(45.40) were achieved from
P
2
V
. In case of yield contributing parameters and yield, the highest number of
flowers plant
3
-1
(32.62), number of fruits plant
-1
(23.72), fruit length (18.80 cm), fruit
diameter (2.16 cm), single fruit weight (15.34 cm), fruit yield plot
-1
(4.36 kg) and fruit
yield ha
-1
(15.15 t) were achieved from the treatment combination of P
whereas the
lowest was recorded from the treatment combination of P
0
V
. In terms of economic
analysis, the highest gross return, net return and BCR (1.70) were obtained from the
treatment combination of P
2
V
3
(Osmopriming; MgSO
4
0
2
V
3
2
- 3 ppm with 10 t ha
vermicompost) whereas the lowest gross return, net return and BCR (1.17) were
obtained from P
0
V
0
. So, treatment combination P
2
V
was found promising for okra
production.
