Mix: Mix of Priestia megaterium B004 + Azotobacter chroococcum A004 with zeolite as a carrier. Values presented are mean values of three replicates ± standard deviation. Means followed by the same letter for treatments are not significantly different according to Tukey Honestly Significant Difference (HSD) test (p < 0.05). Significance levels: ** p < 0.01; *** p < 0.001; ns: not significant.
