الملخص EN

A pot experiment was conducted at the hath-house of the Dept.

of Soil Sci.

and Water Resources, Coll.

of Agric., Univ.

of Baghdad during 2011 winter season, using loamy sand texture soil.

To study effect of biofertilizer in some the biochemical and phsyological parameters on wheat plant under salt stress.

Experiment factor are three salinity levels (0.5, 5.5 and 7.3 dSm-1) coded as C1, C2 and C3 respectively.

Two inoculation type of fungal and bacteria were used four tretments of inoculation (with out inoculation, with mycorrhiza, Gloums intraradics, with bacteria, Azospirillum.brasilense and dual inoculation Gloums intraradics and Azospirillum brasilense) coded as A0, AM, AB, and AMAB respectively, and three replicates due to a Randomized Complete Block Design.

Results showed that an inoculated of mycorrhiza or with Azospirillum bacteria significant reduced salt stress and reduced caused, Na+, Cl- concentration, while increased total chlorophyll, relative water content (RWC), K+, K+:Na+ in shoot and root.

Results showed that Dual inoculation with (Gloums intraradics and Azospirillum.brasilense) was more effective than single inoculation.
