Fertilization of Phaseolus vulgaris with the Tunisian rock phosphate affects richness and structure of rhizosphere bacterial communities

•This work addressed short-lived effects of P fertilization on bacterial community.•Significant difference in richness and bacterial structure between TRP and TSP.•TRP at low P level showed an increase in copiotrophic taxa.•Proteobacteria (Beta) and Actinobacteria were stimulated by TRP at low P level.•Some TRFs affiliated to Rhizobiaceae were inhibited by TSP.
