In order to study the effects of different nitrogen (0, 25 and 50 Kg.ha-1) levels and two levels of Nitroxin biofertilizer (control and inoculation) on yield and its components in three sesame varietes (Darab-14, Jiroft and Yazdi) an experiment was conducted at Agricultural Research Center and Natural Resources of Yazd in 2009. Varietes in main plot, nitrogen fertilizer and biofertilizer as factorial were randomized in sub-plots used in a split plot factorial arranged as a randomized complete block design with three replications. Plant height, number of capsules per plant, number of branches per plant, number of seeds in capsule, 1000 seed weight, seed yield, harvest index, oil percent, oil yield and protein percent were measured. Concerning the effect of varietal differences, results illustrate significance differences between the three varieties in all determined characters except for oil percent. Different nitrogen fertilizer and biofertilizer significantly affected in all determined characters except for oil percent and harvest index.The highest seed yield (1794/4 kg.ha-1) and Protein percent (22/48%) was obtained using Darab-14 with applying 50 kg N ha-1 and applying biofertilizer treatment. Seed yield had positive and significant correlation with capsules and branches per plant, number of seeds in capsul, protein percent and oil yield. Generally, the results showed that use of biofertilizer can be useful in during the decrease use of N chemical fertilizer.
