Sodium (Na+) and potassium (K+) contents, both in mmol g−1 DW, in the shoots of cowpea plants inoculated with Bradyrhizobium or co-inoculated with Bradyrhizobium and PGPB. Absolute control is non-inoculated plants.

Significant difference (p < 0.05) between absolute control and inoculated plants in non-saline conditions by Dunnett's test. In each column, means followed by the same lowercase letters do not differ statistically by Tukey's test (p < 0.05), whereas uppercase letters represent significant differences between control and salt stress conditions.
