A total of 43\u00a0rhizobacteria were isolated from undisturbed plant rhizosphere soils of three different\u00a0locations of Bangladesh and evaluated their plant growth promoting traits, both direct\u00a0and indirect. The study has screened out isolates on the basis of their phosphorous\u00a0solubilization and nitrogen (N) fixation. The phosphate solubilization assay in National\u00a0Botanical Research Institute of Phosphate (NBRIP) medium revealed that 12 bacterial\u00a0isolates were able to solubilize tricalcium phosphate and the rhizobacteria M25\u00a0showed best performance with a PSI of 3.33 at 5 day. Exactly 47% (20 isolates) of\u00a0the isolated rhizobacteria were able to grow in N-free Winogradsky\u2019s medium, which\u00a0is an indication of potential N2-fixers. Among the 20 potential N-fixers, 15 were able\u00a0to grow within 24 hours of incubation indicating that they are more efficient in Nfixation.\u00a0The present study successfully isolated and characterized 43 rhizobacteria.\u00a0Some of these isolated rhizobacteria have potential plant growth promoting traits and\u00a0are potential plant growth promoting rhizobacteria (PGPR) candidate. Considering all\u00a0plant growth promoting traits, the isolate F37 was the best followed by M6. However,\u00a0further experiments are needed to determine the effectiveness of these isolates\u00a0under in vitro and different field conditions to understand the nature of interaction\u00a0with the plant and environment.<\/p>\n<p style=\"text-align: justify;\"><strong>Key words:\u00a0<\/strong>Rhizobacteria,\u00a0Bioinoculants,\u00a0Phosphorus,\u00a0Solubilization,\u00a0N-fixation,\u00a0Plant growth<\/p>\n<p style=\"text-align: justify;\">DOI: <a id=\"pub-id::doi\" href=\"http:\/\/dx.doi.org\/10.3329\/ralf.v2i1.23020\">http:\/\/dx.doi.org\/10.3329\/ralf.v2i1.23020<\/a><\/p>\n<p style=\"text-align: justify;\"><strong>[\/showhide]<\/strong><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #800000;\"><strong><a style=\"color: #800000;\" href=\"http:\/\/agroaid-bd.org\/ralf\/wp-content\/uploads\/sites\/2\/2015\/04\/ag-1.pdf\">Download Full Article PDF<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author:\u00a0Moonmoon Nahar Asha, Atiqur Rahman, Quazi Forhad Quadir and\u00a0Md.
