Abstract Wheat ( Triticum aestivum L. ) can be classified as winter or spring growth habit based on flowering responses to cold temperatures. Wheat ( Triticum aestivum, L.) is one of the most important cereal crop in Egypt and over all the world used in human food and animal feed. The present study aimed to induce sodium azide resistant mutants in Azospirillum strains to be used for better nitrogen fixation in the rhizosphere of Triticum aestivum grown in salinity soil to enhanced non-symbiotic nitrogen fixation capability in salinity soil In conclusion isolation of azide resistant mutants (Azr) of Azospirillium in the present work leads to efficient secrete IAA as a plant hormone In addition, all Azospirillum inoculants appeared significant increase in grains protein content at two seasons above uninoculated plants. Grains protein content and straw protein content at 150 days plant-old were significantly affected by soil type, biofertilizer inoculants, as well as, by the interaction between both as well as, improving biochemical traits such as grain protein contents and leaves chlorophyll concentration |
