Abstract: Azotobacter chroococcum, Bacillus megaterium, Pseudomonas fluorescens, Trichoderma viride and Glomus fasciculatum were efficient PGPRM. Hence, they were subjected to compatibility test by dual culture method. All the four PGPR microorganisms (A. chroococcum, B. megaterium, P. fluorescens, and T. viride) were found to be compatible under in vitro condition both on solid and in liquid media. Population density of inoculated PGPR microorganisms in the cashew rhizosphere at different intervals was found to be maximum in the treatments receiving that organisms alone or with other PGPR microorganism. Population density of inoculated organisms increased gradually up to grafting and there after slight decline was noticed.
