Abstract:
A field experiment was conducted at the research farm of Sher-e-Bangla
Agricultural University, Dhaka, during January to April, 2018 to study the
influence of biofertilizer and phosphorus level on growth, nodulation and yield
of soybean. The experiment consists of two factors- factor A: Biofertilizer
level-2; i) Control (without biofertilzer) (B
0
ii
) and ii) Biofertilizer (B
1
); factor B:
P levels-5; i) Control (no phosphorus) (P
0
), ii) 25% less TSP than
recommended dose (P
1
), iii) Recommended dose of TSP (P
2
), iv) 25% higher
TSP than recommended dose (P
3
) and 50% higher TSP than recommended
dose (P
4
). Biofertilizer was used @ 25 g kg
-1
seed. The experiment was laid out
in split plot design with three replications. Growth, yield attributes and yield
data like plant height, number of branches plant
-1
, dry weight plant
, number of
nodules plant
-1
, pod length, number of pods plant
-1
, 100 seed weight, shelling
percentage, seed yield and stover yield were collected from this experiment.
Data were statistically analyzed using MSTAT-C software program. The
significance of difference among the treatments means was estimated by the
Duncan’s Multiple Range Test (DMRT)at 5% level of probability. The result
revealed that biofertilizer applied treatment (B
1
) was found best by producing
higher yield as well as highest 100 seed weight, number of seeds pod
, pod
length, nodules plant
-1
, and other growth characters. On the other hand, P levels
at 25% higher phosphorus than recommended dose (P
3
) produced highest yield
(3613.00 kg ha
-1
), plant height, branches plant
-1
, dry weight plant
, nodules
plant
-1
, pods plant
-1
, 100 seed weight, stover yield and biological yield. In case
of interaction, B
1
P
3
was found superior by producing highest seed yield
(3714.00kg ha
-1
) and yield attributes like pods plant
-1
-1
-1
-1
(55.40), seeds pod
(2.98). From the result of study, it was revealed that application of biofertilzer
and 25% higher TSP than recommended dose had positive impact on soybean
(BINA Soybean-1).
