Con, T1, T2, and T3 indicate 0, 1 × 10³, 1 × 10⁶, and 1 × 10⁹ spores L⁻¹ suspension, respectively. Soil salt ion content, SAR, and pH were measured on the 27th day after T. asperellum application. C and T indicated cultivars and treatments, respectively. Different letters within a column indicated significant differences at 5% probability level, and the numerical value represented the mean value of five repeats. Differences between treatments were calculated for each particular cultivar. NS, not significant. * and **, significant at the 0.05 and 0.01 probability level, respectively.
