Recently, biofertilizer application is growing to meet sustainable agriculture goals. The present experiment was designed to evaluate four nitrogen levels (0, 60, 90 and 120 kg N.ha-1) as main plots, two supernitroplus biofertilizer levels) with and without biofertilizer) as sub-plots on yield and yield components of three sesame cultivars (Naz, Oltan and Varamin (as sub-sub-plots in a split-split plot experiment arranged in a randomized complete block design with three replications. Nitrogen rates had a significant effect on number of capsule per plant, number of seed per capsule, 1000-seed-weight, number of stem branch per plant and seed yield. Application of biofertilizers could increase percentage of fertile flower in all cultivars while number of capsule per plant increased only in Varamin. Application of biofertilizer caused an increase in seed yield by 10% compared to control. Optimum amount of seed yield was belong to Oltan )3240 kg.ha-1 (with 60 kg N.ha-1, Naz 2971 kg.ha-1) and Varamin (2319 kg.ha-1) with 90 and 120 kg N.ha-1. Oltan was superior than Naz while Naz had better performance than Varamin for seed yield.
