Salinity negatively affects rice growth and yield by causing nutritional imbalances, osmotic stress, and ion toxicity. This study aimed to examine the synergy between diazotrophic bacteria and P-solubilizing bacteria in increasing rice plant growth and yield in high salinity. The research was conducted at the Agronomy & Horticulture Laboratory and Experimental Farm, Faculty of Agriculture, Jenderal Soedirman University, Indonesia, from July to December 2024, using a floating raft hydroponic system with AB mix, and salinity was maintained at 6.5 dS m?¹ using NaCl. The research used a Randomized Block Design with four replications. The treatments include Diazotrophic bacteria, including Acinetobacter junii strain WR4 (A) and Bacillus tropicus strain CU96 (B), while the P-solubilizing bacteria used are Priestia megaterium strain NRRL B-350 (P). The results showed that the application of diazotrophic and phosphate-solubilizing bacteria significantly improved the agronomic and physiological performance of rice plants under high salinity stress. The consortium of diazotrophic and P-solubilizing bacteria increased resistance to salinity stress by increasing proline levels by 173.36% and increasing the K?/Na? ratio. Inoculation of diazotrophic and P-solubilizing bacteria was able to increase yield by an average of 61.79%.
