Abstract :

In order to investigate the effect of organic, bio-chemical fertilizers on yield and efficiency components of sesame, a factorial experiment was conducted in Randomized Complete Blocks Design with three replications in two crop years in Kermanshah in 2017-2018. The first factor consisted of nitrogen fertilizer with four levels of zero, 33, 66 and 100% nitrogen, and the second factor consisted of inoculation with four levels of seedless biofertilizer, Azotobacter inoculation, Azospirillum inoculation and mixing with both bacteria. . The experiment was conducted each year on three land plots including control, 10 ton manure and 10 ton municipal waste compost. The results showed that the effect of nitrogen and biological fertilizer levels on grain yield and biological yield were significant in all three environments. The highest values of grain yield and biological yield were obtained in the combination of Azotobacter and Azesprillium fertilizers in all three media. The highest grain yield (1298 kg / ha) was observed in the control medium in 100% nitrogen requirement, in the fertilizer medium in 33% nitrogen requirement (1565 Kg / ha) and in the compost medium were obtained with 66% nitrogen (1799 kg / ha). Overall, the results showed that the combination of biological fertilizers with manure or compost could save the fertilizer application and also have acceptable yield. Also, the use of biological fertilizers and organic fertilizers increased the efficiency of use of the elements, which could eventually increase round yields in addition to lower production costs.
