The effect of six phosphate-solubilizing fungi (PSF, two strains of Aspergillus
awamori, and four of Penicillium citrinum) isolated from rhizosphere of various crops, was
observed on the growth and seed production of chickpea plants (Cicer arietinum L. Cv. GPF2) in
pot experiments. The phosphate (P) solubilizing activity of PSF in liquid varied from 38 to 760
mu g ml(-1) for tricalcium phosphate (TCP) and 28-248 mu g ml(-1) for mussoorie rock phosphate
(MRP). All PSF isolates were biocompatible and produced growth-promoting hormone, Indole acetic
acid (IAA), varying in concentration from 2.5 to 9.8 mu g ml(-1). Of the various pot experiments
carried out in green house, maximum stimulatory effect on chickpea plants growth was observed by
inoculation of two A. Awamori strains. This treatment resulted in 7-12% increase in shoot height,
nearly three-fold increase in seed number and two-fold increase in seeds weight as compared to
the control (un-inoculated) plants. Inoculation of four strains of P. Citrinum exhibited lesser
stimulatory effect. It showed 7% increase in shoot height, two-fold increase in seed number and
87% increase in seeds weight as compared to the control plants. However, a consortium of all the
six fungal isolates showed no stimulatory effect on chickpea plants growth. (c) 2007 Elsevier
