Fig. 2. Influence of indigenous AMF and root nodulating rhizobia on soil enzyme
activities assessed in the rhizosphere of soybean grown under sterilized
and un-sterilized microcosm conditions; Data are mean of three
replications; LSD, least significant difference (P = 0.05) by DMRT of
ANOVA; ACP, Acid phosphatases; ALP, Alkaline phosphatases; FDA,
fluroscein diacetate; Treatments T1, Absolute control; T2, AMF; T3,
Bradyrhizobium japonicum, 5a; T4, Bradyrhizobium liaoningense, 17c; T5,
Recommended dose of fertilizers (RDF); T6, T2 + T3 + T4; T7, 50 % of RDF
+ T2; T8, 50 % of RDF + T3; T9, 50 % of RDF + T4; T10, 50 % of RDF + T2 +
T3 + T4
maintain higher available phosphorus in
the soil. This meant that inoculation of
AMF with Bradyrhizobium with and
without 50 per cent RDF showed increase
mineralization of unavailable P from
native pool for P uptake to produce
higher yield and N uptake in roots and
also increasing available P content in soil.
The two factor analysis revealed that
irrespective of treatments, the effect of
soil conditions did not influence N–
uptake, whereas soil available P was
influenced significantly. There was
significantly higher available P in the
