hirty-two isolates were recovered from farmland soil samples of the Banasthali region, Rajasthan, India, out of which 16 showed
phosphate solubilizing potential. These microorganisms were further screened based on solubilization efficiency of inorganic
phosphate sources in Pikovskaya agar and broth media containing tricalcium phosphate as an insoluble source of phosphorus.
Isolates S33 showed the highest phosphate solubilizing potential, and later identified as
Aspergillus tubingensis
, was selected it for
further work. This isolate could solubilize other inorganic forms of phosphorus (P) viz. dicalcium phosphate, ferric phosphate and
Udaipur rock phosphate. The efficiency of
Aspergillus tubingensis
S33 was further studied in semi- arid soils in a pot experiments to
evaluate the effects of this fungi on the enhancement of P uptake by plants, available P status in the soil, dry matter production and
grain yield of wheat (
Triticum aestioum L
.) and mung bean (
Vigna radiata
). Inoculation of
A. tubingensis
S33 significantly improved
dry matter and grain yield in both crops. In general, there was a significant improvement in P uptake by plants and extractable P
status in the soil. The results suggested that
A. tubingensis
S33 can play important role in wheat and mungbean growth promotion
and increase in soil available P.
