Forty ,isolates  of phosphat dissolving Microorganisms (PDM) selected at random and screened for their efficiency .All isolates had an ability to solubilize inorganic phosphate. The more active 10 isolates were further studied for ability to solubilize phosphorus in Bunt and Rovira agar medium to determined solubilizing index .The counts of bacteria,spore formers,PDM and actinomycetes were higher in either amended or inoculated treatments compared to unamended or uninoculated. Generally high counts of these microorganisms were recorded in the rhizosphere of plants inoculated with mixed inocula .Difference in counts of these  microorganisms were found according to p-fertilizer sources as well as type of microbial inocula.
The highest values of vegetative growth parameters were obtained on plants fertilized by rock phosphate compared with those fertilized with super phosphate. Generally nitrogen and phosphorus percentages varied according to PDM and phosphorus fertilization  source .In treatment inoculated and amended with rock phosphate higher N% and P% were recorded compared to inoculated with inoculant with mixed followed by VAM then PDB.
