An experiment was conducted at the experimental field of the Department of
Soil Science, Bangladesh Agricultural University. Myniensingh during
Januan' to May 2003 to study the effect of added P. Mo and
I3radyrhizobiurn
inoculant on nodulation, yield and yield contributing characters of two
soybean cultivaj-
s, Pb-I and 0-2. The treatments were: Control, Inoculurn,
P+Jnoculum, Mo+Inoculum, P+Mo+Inoculum. The rates of P, Mo and
Bmdvrhizobium
inoculant were 40 kg P ha
1
. 1 kg Mo ha1
and 15 g inoculant
kg' seed, respectively. TSP was used as a source of!' and sodium molybdate
as that of Mo. Basal application of 40 kg K
had,
15kg S ha
1
and 2 kg Zn h
ad
was made to all plots for crop raising. The variety was placed in the main
plots and the fertilizer and
J3radyrliizobiutn
inoculant were placed in the subplots.
At 75 EMS, 10 plants were uprooted from each plot for recording data
on nodulation and growth characteristics. The crop was harvested at maturity
after 120 DAS. Between varieties, the 0-2 showed higher nodulation, number
of pods and seeds plant
1
compared to Pb-I variety. On the other hand,
variety Pb-I gave significantly higher 100-seed weight, seed and stover
yields comparcd to the 0-2.
Bra dyrhizobi
mu
inoculation significantly
increased nodulation, number of pods and seeds plan(' and finally seed and
stover yields of' soybean. The combined application of P and Mo with
Bradyr/2izobiwn
inoculation further increased the nodulacion and yield of
soybean varieties.
Bradyrhizobium
inoculation was found essential for
soybean cultivation at BAU Farm and an application of P and Mo further
increased the yield.
