Abstract
To study the effect of complete soil sterilization on corn plant growth Zea mays and Phosphorous availability comparable to with that with unfertilized treatments, Fertilized in phosphate, fertilized and inoculated in B2 Bacillus megaterium and F3 Asperjellus olivaco-fuscus phosphate dissolving in the same treatments and design mentioned in (part one of the study). The results obtained showed that complete sterilization of soil didn`t cause any clear changes in available Phosphate behavior in soil, but limited plant shoots , shoots dry matter in sterilized treatments (control) and also caused an increase in corn shoots concentration of both P and N. The results also indicated to a convenient P fertilizers used in the study and no important role of phosphate solubilizing Microorganisms in the lathe house experiment which lasted (45) daysafter inoculation was detected .
