In order to study on the effect of nitrogen, vermicompost and nitroxin biofertilizer on growth indices and phenology of sesame a field experiment was carried out at Behbahan in summer of 2009. Treatments were arranged in a factorial experiment based on RCBD with three replications. Three rates of nitrogen fertilizer (50, 75 and 100% of region recommended nitrogen rate,) as a first factor, three rates of vermicompost (0, 5 and 10 t/ha) as a second factor and two levels of nitroxin biofertilizer application (seed inoculation and non inoculation) as a third factor, were used. The result showed that nitroxin inoculation and the use of 5 and 10 t/ha vermicompost increased maximum LAI sesame by 7.1, 23.11 and 31.19%, respectively. With nitrogen fertilizer, vermicompost and nitroxin inoculated the maximum CGR of sesame increased significantly. Result also showed that vermicompost and nitroxin application had a positive and significant effect on phonological stages of sesame. So that use of vermicompost decreased rate of GDD requirement for sesame emergence significantly. Also inoculation with biological fertilizer nitroxin reduced the rate of emergence by 17.4%. With vermicompost application the period of planting to appearance of capsule has increased and reached to its highest level in 5 t/ha. Nitroxin application increased grain yield by 8.5%. Interaction of nitrogen and vermicompost showed that the most grain yield (1352 kg/ha) was obtained with applying 10 t/ha vermicompost with 75 % of region recommended nitrogen rate.
