The values are the mean±standard deviation (SD) (n = 3), and those with the same letter in each row or column indicate the absence of a significant difference among the different treatments and different days (P > 0.05). The capital letters indicate significant differences among the different days, and the lowercase letters represent significant differences among the different treatments. CK: control soil without bacteria or nematodes; B: soil inoculated with B. megaterium JX 15; N1: soil inoculated with the isolated Cephalobus sp.; N2: soil inoculated with the isolated Mesorhabditis sp.; BN1: Soil inoculated with B. megaterium JX 15 and the Cephalobus sp.; and BN2: soil inoculated with B. megaterium JX 15 and the Mesorhabditis sp.
