Agricultural productivity is severely hampered by salinity stress, especially in areas where soil salinization is significant. The purpose of this study is to determine whether plant growth-promoting rhizobacteria (PGPR), which were isolated from the rhizosphere of Rosmarinus officinalis (rosemary), may improve Brassica juncea (mustard) resistance to salt. The characteristics of the isolates that promote plant growth, such as phosphate solubilisation, nitrogen fixation, and the synthesis of indole-3-acetic acid (IAA), were described. At sodium chloride (NaCl) concentrations ranging from 1% to 5%, the salt tolerance of several PGPR strains was evaluated. The effects of PGPR inoculation on mustard seedlings in saline environments (300 mM, 500 mM, 700 mM, and 900 mM NaCl) were assessed in pot experiments. The findings showed that PGPR considerably increased the growth of seedlings under salt stress, indicating that they could be used as biofertilizers in sustainable farming.
