Abstract: 
In order to study on effect Azospirillum on sunflower cultivar seeds that produced under low water stress, an experiment was conducted in form of factorial completely randomized design with three replications. Treatments are include water stress [Irrigation plants after 60 (Normal irrigation), 120 (Mild stress), 180 (Severe stress) mm evaporate from pan class A, with five Cultivar and Seed inoculation [Inoculation with Azospirillum, No inoculation]. Results showed that water stress decreased abnormal seedling, rust seed, vigor and seedling weight. Azospirillum increased root, stem and seedling length respectively 5, 20 and 11 percent and root, stem, seedling fresh weight respectively 25, 18, 19 percent than no inoculation. Seeds produced under water stress had 13 percent higher than normal irrigation. Increased 4 percent seed viability of seeds produced under severe stress. Seeds produced under water stress had lower rust seed amount and Azospirillum decreased than no inoculation. With attention to negative effect of water stress, Azospirillum increased seed viability, length, weight and vigor seedling.
