The effects of inoculation of thiobacillus and the type of nitrogen fertilization (urea and ammonium sulphate fertilizers) on yield and yield components of rapeseed cultivars (Okapi, SLM 046 and Reagent * Cobra) were studied. The experiment was carried out as spilit plot factorial in randomized complete block design with 4 replications in Shahrood University of Technology. Reagent * Cobra cultivar produced 4400 Kg/ha which in comparison with the other cultivars was the highest. The effect of thiobacillus on yield and some other traits was significant. Thiobacillus application improved seed yield for about 12.2 percent in comparison with check cultivar. The effect of thiobacillus application on plant height, number of pods in main stem and secondary branch as well as number of leaves in plants was significant. While the effect of nitrogen source (urea and amonium sulphat) on yield was not significant. Interaction between application vs. no application of thiobacillus and cultivars was significant regarding seed yield, length of secondary branch and length of pod on the secondary branches.
