Abstract:
The experiment was conducted at Sher-e-Bangla Agricultural University (SAU) farm, Dhaka
during the period from march 2021 to July 2021 in order to effect of Zn and B on the growth
and yield of okra (BARI dheros 2). The experiment consisted of two factors: Factor A: Zn
application as (i) Zn
0
: 0 kg Zn ha
-1
(ii) Zn
1
: 3 kg Zn ha
-1
as soil application (iii) Zn
: 3 kg Zn
ha
-1
as foliar application. Factor B: B application as (i) B
0
: 0 kg B ha
-1
(ii) B
as
soil application (iii) B
2
: 2 kg B ha
-1
as foliar application. The experiment was laid out in a
Randomized Complete Block Design (RCBD) with three replications. Data on the growth,
yield contributing characters and yield were recorded statistically significant variation in
results was observed between the treatments. In terms of Zn effect, the highest plant height
(167 cm), number of leaves plant
-1
(44.8) and number of branches plant
(3.78) were
observed in Zn
2
(3 kg Zn ha
-1
as foliar application) treatment. Again the highest number of
fruits (26.9), yield (14 t ha
-1
) were noted for Zn
2
(3 kg Zn ha
-1
1
2
: 2 kg B ha
-1
as foliar application)
treatment.
In terms of B effect, the highest plant height (156 cm), number of leaves plant
(47) and
number of branches plant
-1
(3.83), numbers of fruits plant
-1
(27.2) and yield (11.8 t ha
) were
recorded with B
2
(2 kg B ha
-1
as foliar application) treatment. Combined effect of Zn and B
fertilizer application on yield showed statistically significant variation compared with control.
The highest plant height (180 cm), number of leaves plant
-1
(50.0) and number of branches
plant
-1
(4.40), number of fruits plant
-1
(30.0) and yield (17.5 t ha
-1
) was noted with the
treatment combination Zn
2
B
2
(3 kg Zn ha
-1
with 2 kg B ha
-1
as foliar application).
