Possible roles of nitrogen fixation and mineral uptake induced by rhizobacterial inoculation on salt tolerance of maize.

Pot experiments were conducted to evaluate the possible roles of nitrogen fixation and/or enhanced mineral uptake by Azospirillum lipoferum and Bacillus polymexa inoculation in improving salt tolerance of maize plants. Plants were inoculated and grown under salt stress (osmotic potential: -0.3, -0.
