Abstract:
An experiment was carried out at Sher-e-Bangla Agricultural University farm, Dhaka
to investigate the growth and yield response of mungbean (Vigna radiata L.) as
affected by nitrogen and biofertilizer management during the period from September
to November, 2014. The experiment consisted of two factors. Factor A: Nitrogen
fertilizer (4 levels); N
0
: No nitrogen (Control), N
1
: 20 kg N ha
-1
as basal application, N
:
20 kg N ha
-1
at branching stage and N
3
: 20 kg N ha
-1
at flowering stage, and factor B:
Rhizobium inoculum (3 levels); R
0
: No Rhizobium (Control), R
1
: Rhizobium @ 5 kg ha
and R
2
: Rhizobium @ 8 kg ha
-1
. The variety, BARI Mung-6 was used in this experiment
as the test crop. The experiment was laid out in split-plot design with three replications
where levels of nitrogen were assigned in the main plot and doses of Rhizobium
inoculum in the sub-plot. Plant height, leaf area plant
-1
, dry weight plant
, branches
plant

, nodules plant
-1
, pods plant

, pod length, seeds pod
-1
, weight of 1000 seed, seed
yield, stover yield, biological yield and harvest index were tested under different
treatments. Results revealed that, N
2
and R
treatment influenced significantly on most
of the growth, yield parameters and yield of mungbean. N
2
gave the higher yield (1.37
t ha
-1
) which was 77.92% higher than N
0
(0.77 t ha
-1
2
). Application of Rhizobium
inoculums greatly influenced the seed yield and R
2
produced (1.28 t ha
) which was
28.00% higher than R
0
(1.00 t ha
-1
). The highest seed yield (1.69 t ha
) was recorded
from the treatment combination of N
2
R
2
and the minimum (0.73 t ha
) was recorded
from the interaction of N
0
R
. The maximum yield might be attributed to higher pods

, seeds pod

1
and 1000-seeds weight. Application of 20 kg N ha
-1
at branching stage
as split and Rhizobium inoculums @ 8 kg ha
-1
could be the best fertilizer and inoculum
management for cultivation of mungbean for higher yield.
