In order to study the effect of bio-fertilizers on sesame genotypes yield under drought stress, an experiment was conducted based on split-split plots experiment in a randomized complete block design with three replications at the Agricultural Research Station, shahid Bahonar University. Treatments included as follow: irrigation base on water evaporation from pan with three levels (50, 90, 130 mm) in the main plots and two types of fertilizers namely nitrazhin and phosphate 2 as two sub treatments and three cultivars: Sirjan, Birjand and Jiroft as sub sub-treatment randomly assigned to subplots The results showed that drought stress caused a significant reduction in the yield of capsules, number of seeds per capsule, biological yield, yield and oil content. The effect of fertilizer on leaf number was significant at 1% level and nitrazine fertilizer had the greatest effect. There was a significant difference in the number of capsules or oil percent between varieties. The maximum performance (7.732 kg/ha) was due to primary stress (50 mm evaporation) and Sirjan cultivar. There is a significant interaction between fertilizer and stress and Nitrazhin fertilizer can reduce the effect of stress on the number of capsules.
