Two cumin local varieties including Ardestān and Mashhad Ardehal were used. So, in a rudimentary experiment, the tolerance threshold was at ۱۵۰ and ۲۵۰ mM of Sodium Chloride for both varieties. The result showed that salinity and inoculation with bacteria had a significant effect on the percentage and germination rate, root length, plant height, and seed vigor. Increased concentrations up to ۲۵۰ milli molar sodium chloride resulted in a significant reduction in germination percentage and germination rate, root length, stem height, seed vigor, grain yield and essence yield. Also, the results presented that in both varieties and at all levels of salinity,inoculation with bacteria compared to the control, lead to a significant increase in chlorophyll (a, b), carotenoids, catalase, ascorbate peroxidase, plant height, grain yield and essence yield. Overall, Ardestan variety showed higher value for plant height, Chlorophyll (a, b), the carotenoids, catalase, ascorbate peroxidase and essence content compared to Mashhad Ardehal variety. In general, the result of this experiment can be used to decrease salinity effects by azotobacter inoculation and increase grain yield and essence content of cumin.
