Sesame is an important and useful oil crop. This study was conducted to evaluate of the effects of nitrogen and biological fertilizer on sesame crop as a factorial experiment based on a randomized complete block design with three replications in the research farm of the university of Zabol. Experimental factors were nitrogen (N) fertilizer at four levels (0, 160, 240 and 320 kg ha-1 N as urea) and nitroxin at two levels (inoculated and non-inoculated). Nitroxin application significantly increased plant height, number of lateral branches, 1000-seed weight, number of seeds per capsule, number of capsules per plant, seed yield, oil yield, and protein content. When 240 kg ha-1 of urea was applied, number of lateral branches, 1000-seed weight, number of seeds per capsule, number of capsules per plant, and protein content increased by 50, 12, 18, 45 and 11%, respectively. The interaction of treatments revealed that inoculation of seeds with nitroxin along with 75% recommended N application increases plant height, seed and oil yield, respectively, by 28, 58 and 56% compared with non-inoculated seed and non N fertilizer application. generalley the results indicated that besides improving of growth condition, seed inoculation with nitroxin can be usefull in reduction of the application of chemical nitrogen fertilizers.
