Soil phosphorus is heavily restricted by soil acidification and salinization. There a need to determine biological solution for this issue replace the overuse of chemical fertilizer that aggravates adverse conditions, such as salinity, acidity, metallic toxicity. Therefore, study aimed at determining dynamics in terms soil, growth, yield rice under supplementation phosphate (P)-solubilizing purple nonsulfur bacteria (PNSB), Cereibacter sphaeroides ST16 ST26, salinized collected from An Bien district, Kien Giang province, Vietnam, greenhouse conditions. The experiment followed completely randomized block design with two factors four replications. In particular, reduced percentages P (A) were 0%, 25%, 50%, 75%, 100% P. supplementations C. strains (B) negative control, ST16, mixture both ST26. results showed supplying ST26 insoluble content 10.1–10.6% Fe-P, 10.3–12.2% Ca-P, 12.7–43.1% Al-P increased available 8.33–27.8%, leading total uptake plants increasing 29.4–56.1%. also Na+. growth components rice, greater 26.5–51.0%. Supplying each strain 50–100% recommended. Ultimately, inoculation bacterial allowed reduction percentage recommended but remained still.
