Salinity decreases the water absorbing potential of plants, immediately decreases the growth rate, reduction of water stress and reduces the photosynthetic activity in plants. High salinity interfere to plant growth and can also leads to physiological drought conditions and ion toxicity. It can also injure cells in transpiring leaves, which leads to growth inhibition. Among the PGPR Azospirillum act as a major role in salinity soil Azospirillum is microaerophilic, gram negative and spiral shape bacterium. It is asymbiotic nitrogen fixer which able to fix the atmospheric nitrogen and make it available to plants. It is beneficial to plants through mechanisms related to enhancement of plant growth, increases the mineral uptake, increase the dry matter, improve the water absorption and improve the yield. The main aim of this study is to identify the salt tolerant Azospirillum strains from the coastal saline soils. From this study, we isolated Azospirllum strains from coastal saline soil which could grow in higher level of pH, NaCl, concentration and temperature range. The Azospirillum isolates AZST2, AZST5, and AZST7 were found to have ability to grow under varied conditions like high pH, NaCl concentration and temperature which showed the potential to use them as successful inoculants for coastal saline agriculture.
