Effect of Chemical (Urea), Organic (Vermicompost) and Biological (Nitroxin) Fertilizers on Quantity and Quality Yield of Sesame (SesamumindicumL.)

In order to study the effect of nitrogen, vermicompost and nitroxin biofertilizer on quantity and quality yield 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, equals to 25, 37.5 and 50 kg/ha nitrogen from urea, respectively) 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. Results showed that treatments had a significant effect on yield and yield components of sesame. Nitroxin application increased grain yield 8.5 percent. Interaction of nitrogen and vermicompost showed that the most grain yield (1352 kg/ha) was obtained with applying the 10 t/ha vermicompost with 37/5 kg/ha of nitrogen rate while the lowest grain yield (947 kg/ha) obtained from without vermicompost treatment with 25 kg/ha of nitrogen rate. The highest oil percent (45%) obtained with application of 37/5 kg/ha nitrogen with 10 t/ha vermicompost and the lowest of it (40 %) obtained in 50 kg/ha nitrogen with 10 t/ha Vermicompost. The oil percentage in 50 kg/ha nitrogen treatment, vermicompost application and Nitroxin inoculation decreased the significantly. By increasing nitrogen fertilizer, vermicompost and nitroxin, protein yield and percentage increased significantly.
