Abstract: Low-cost, and environmentally friendly agricultural practices have received increasing attention in recent years. Indeed, microbial inoculants based on phosphate (P) solubilizing bacteria (PSB) appear to be an emerging biological solution to increase P availability in the plant rhizosphere. The present study was conducted on PSBs isolated from soils located at different bioclimatic stages in Morocco, from various rhizospheres of leguminous cultures to assess PSBs response on two papilionaceae species (Pea and Broad Bean). Phosphate solubilization potency was assessed by the vanadate-molybdate method. Of all tested strains (64), the AS61 isolate performed best in NBRIP liquid medium, with 0.148 g.l-1 of soluble P. Sterilised Pea and Broad Bean seeds were inoculated with six strains (109 CFU mL-1), individually and incubated at 28 ± 2˚C in Petri dishes containing 0.25% agar water. Seedlings treated with PSBs promoted germination and seedling vigour between 7% and 15%, compared to non-inoculated control. Therefore, this study reveals the potential effect of PSBs to support rhizobacterium growth-promoting traits.
