The MDA, proline and soluble protein content of plants response to drought and bacterial inoculation. Plants grew in soil for two months and subjected to different drought levels for 30 days, the MDA, soluble proteins and proline content of un-inoculated Astragalus (dark green) and consortium 6 inoculated Astragalus (earth yellow) under the different level of drought were determined. Each treatment had four replications. ‘ns’ indicated no significant difference. The asterisks indicated significant difference according to Student’s t test, ‘*’: P ≤ 0.05; ‘**’: P ≤ 0.01
