Data in the table are expressed as the mean ± SE. Values in columns followed by the same letter do not differ significantly at P <0.05 by LSD multiple range test. Fm, Dv and Fm+Dv represent inoculation with Funneliformis mosseae, Diversispora versiformis and the combination of F. mosseae and D. versiformis, respectively; ns, not significant at P > 0.05;

* P < 0.05.
