Abstract:
A field experiment was conducted for evaluating the effect of organic and inorganic fertilizer
with foliar application of boron on the growth and yield of mungbean at the research field of
the Department of Agronomy, Sher-e- Bangla Agricultural University, Dhaka from March to
June 2019. The experiment consisted of three levels of fertilizers viz.,F
1
(RD) of NPK fertilizer, F
2
: Recommended dose (RD) of cowdung, F
3
ii
: Recommended dose
: Half recommended
dose of NPK fertilizer and half recommended dose of cowdung and Boron was applied by
four levels viz., B
1
:100% RD as basal, B
2
: 80% RD as basal + 20% foliar spray (FS) of
boron at pre flowering, B
3
: 60% RD as basal + rest 40 % as foliar spray of boron at pre
flowering, B
4
: 40% RD as basal + 60 % as foliar spray at pre flowering stage. The
experiment was set up in a split-plot design with three replications. Data recorded on the basis
of plant height, leaves plant
-1
, branches plant
-1
, dry weight plant
-1
, pods plant
,
1000-seed weight, pod length, seed yield, stover yield and biological yield were found
statistically variable with treatments. The result revealed that treatment F
1
(recommended NPK
fertilizer) showed the highest plant height (55.00 cm), dry matter weight (8.23 g), Pod length
(8.04 cm), number of pods plant
-1
(19.43), seed yield (1.17 t ha
-1
-1
, seeds pod
) and stover yield (3.8 t ha
).
On the other hand, the highest dry weight plant
-1
(4.40 g), 1000-seed weight (41.741g) and
seed yield (1125.6 kg ha
-1
) were recorded from B
3
(60% RD as basal + rest 40% as FS at PF).
Result also showed that most of the treatment combinations gave the statistically similar
results in case of seed yield where numerically the highest seed yield (1356.7 kg ha
) was
recorded in F
1
B
3
. Numerically the highest stover yield (3.953 kg ha
-1
) and Biological yield
(5310.0 kg ha
-1
) was recorded from F
1
B
3.
The combine application of organic and inorganic
fertilizer influence the growth parameter of mungbean. It may be concluded that foliar spray
of boron increase the yield of mungbean compare to basal application along with
recommended dose NPK fertilizer
