In this study, effects of bio-fertilizers on yield potential and agronomic characters of safflower (Carthamus tinctorius L.) cultivars under different irrigation regimes were evaluated. Experimental design was RCBD with split plot factorial arrangement and 3 replication that was done on growing season of 2010-2011 at Kerman, (Iran). Different irrigation intervals included 5 days, 10 days and 15 days was applied in main plot and two levels of bio-fertilizers control and Azotobacter sp.andAzosprillum sp.+ phosphate bio-fertilizer as well as three cultivars (Goldasht, Sina and Mex. 22-191 line) were placed as sub plot with factorial arrangement and different agronomic traits were measured. Results showed that all of the traits significantly affected by irrigation regimes except harvest index. Delay in irrigation from 5 to 15 days reduced 33.11% of the seed yield, also all traits except number of seed per head and harvest index significantly affected by application of bio-fertilizers. There were significant differences in all of the measured traits except harvest index among the cultivars that represented variation among them while Irrigation×cultivar intraction was no significant that represented same responses of cultivars to different irrigation regimes. Irrigation×fertilizer×cultivar interaction effects were significant for number of head per plant and 1000-seed weight and the interaction effect of fertilizer×cultivar was significant for biological and seed yield. Biological and seed yield increased with application of bio-fertilizers compared to the control. According to the obtained results the highest seed yield was obtained from Mex. 22-191 line, in application of bio-fertilizer conditions
