خلاصه مقاله:
Drought stress as the most important abiotic factor for limiting growth, adversely affects crop growth and production. 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 (۵۰, ۹۰, ۱۳۰ mm) in the main plots and two types of fertilizers namely nitrazhin and phosphate ۲ 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 ۱% 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 (۷.۷۳۲ kg/ha) was due to primary stress (۵۰ 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.
