Abstract:
A field experiment was conducted at the research farm of Sher-e-Bangla Agricultural
University, during Kharif-1 (March to June), 2014 to study on the feasibility of reducing
nitrogenous fertilizer use through bio-fertilizer on Mungbean. The experiment comprised
with 2 factors viz. A) Variety-3: V
1
= BARI mung 5, V
2
= BARI mung 6, V
= BINA
mung 8; B) Bio-fertilizer and nitrogenius fertilizer combination-5: T
= Recommended
nitrogenous fertilizer, T
2
1
= Bio-fertilizer (120g) + 25% nitrogenous fertilizer (urea) of the
recommended dose, T
= Bio-fertilizer (120g) + 50% nitrogenous fertilizer (urea) of the
recommended dose, T
3
= Bio-fertilizer (120g) + 75% nitrogenous fertilizer (urea) of the
recommended dose, T
4
= Bio-fertilizer (120g) + 100% nitrogenous fertilizer (urea) of the
recommended dose. The experiment was laid out in split plot design with three
replications. Results revealed that, among all varieties BARI mung 6 gave the highest
seed yield (1.58t ha
5
-1
) which may be attributed to higher number of pods plant
(
(24.54),seeds pod
-1
(11.06) and 1000 seed weight (44.09g). Among bio-fertilizer doses,
the treatment T
5
gave highest
seed yield (1.651 t ha
-1
) as this treatment gave highest
number of pods plant
-1
( 24.90), seeds pod
-1
(10.84) and 1000 seed weight (42.33g). It is
also evident that T
4
, T
3
and T
1
treatment also similar with T
treatment. And interaction of
V
2
T
5
gave higher number of number of pods plant
-1
5
(27.62), seeds pod
(12.38), 1000
seed weight (46.50g), seed yield (1.84 t ha
-1
) and harvest index (32.73 %). As treatment
T
5
(1.651 tha
-1
), T
4
(1.623 t ha
-1
) and T
3
(1.591 t ha
-1
) showed statistically similar seed
yield. So, 50% urea can be reduced by adding bio-fertilizer with urea without sacrificing
seed yield of mungbean. This is the result of single year experiment. So, for higher
acceptibility of the result this experiment may be conducted in different agro-ecological
zone of Bangladesh by using different types of Bio-fertilizer and varieties.
