Abstract:
The experiment was conducted in the Horticulture Farm, Sher-e-Bangla
Agricultural University, Dhaka during October 2018 to February 2019. The
experiment consisted of two factors, such as Factor A: Boron (3 levels) as- B
0
: 0.0
kg B ha
-1
, B
1
: 1.0 kg B ha
-1
, B
2
: 2.0 kg B ha
ii
-1
and Factor B: Zinc (4 levels) as- Zn
0
:
0.0 kg Zn ha
-1
, Zn
1
: 1.0 kg Zn ha
-1
, Zn
2
: 2.0 kg Zn ha
-1
, Zn
3
: 3.0 kg Zn ha
which
was laid out in Randomized Complete Block Design with three replications.
Different levels of boron and zinc influenced significantly on most of the studied
parameters. In case of levels of boron, the highest curd yield (23.30 t ha
) was
recorded from 2.0 kg B ha
-1
and the lowest yield (19.07 t ha
-1
) was found from 0.0
kg B ha
-1
. For levels of zinc, 3.0 kg Zn ha
-1
performed the highest curd yield (23.40
t ha
-1
) and the lowest yield (19.01 t/ha) was recorded from 0.0 kg Zn ha
. For
combined effect, the highest curd yield (26.00 t ha
-1
) was found from B
2
and
the lowest yield (18.04 t ha
-1
) from recorded B
0
Zn
0
. The highest benefit cost ratio
(2.50) was observed from treatment combination B
2
Zn
3
and the lowest (1.74) was
found from B
0
Zn
0
. So, 2.0 kg B ha
-1
with 3.0 kg Zn ha
-1
should better performance
in terms of growth, yield and yield contributing characters of broccoli.
