Rapeseed (Brassica napus L.) is a globally significant oilseed crop with high economic value. However, water deficit significantly limits its growth and productivity. Exopolysaccharides (EPS)-producing bacteria offer promising strategy to counteract drought stress, leveraging their retention capabilities plant growth-promoting (PGP) properties. This study was conducted characterize the PGP traits of selected EPS-producing strains evaluate efficacy in enhancing rapeseed resilience under conditions. Among five evaluated, Pseudomonas protegens ML15 for best performance. strain demonstrated range traits, such as solubilization phosphate, potassium, zinc, alongside production ammonia, siderophores, proline. It also exhibited antioxidant activity ability form biofilms, even water-stressed Inoculation increased germination percentages seedling length. Notably, whether plants were subjected drought-induced stress or maintained normal conditions, treatment P. inoculation consistently improved length overall biomass. Under drought-stressed inoculated reduced malondialdehyde levels vegetation indices, chlorophyll, protein, proline, phenolic content. They showed enhanced enzymes, catalase peroxidase, compared uninoculated plants. These findings underscore potential like mitigate plants, providing ecological benefits that support agricultural sustainability.
