Abstarct: This experiment was done as considering the effect of sulfur, thiobacillus and vermicompost in yield and chickpea yield component in research farm of agricultural faculty, shahrood industnal industrial university in 3 repeat as accidental factorial in block. The experiment factoes included: sulfur in 3 level A1, A2 and A3 (0, 300 & 600 kg per hectar), the bacteria of thiobacillus in 2 level (lack of insemination B1 and consumption of 14¬ kg per hectar B2) and vermicompost in 2 level (lack of consumption C1 of 5 ton per hectar C2).The result of this experiment showed that the application sulfur, thiobacillus and vermicompost had significant effect in yield and yield component. Also the effect of sulfur, thiobacillus and re effect of the 2 in amount of sulfur in seed has known significant. Increasing sulfur, thiobacillus and vermicompost in soil had significant decreasing pH in soil. Sulfur and thiobacillus had significant effect in all studied attributes. Also vermicompost had significant increasing in all studird attributes except of the amount of sulfur in plant. The re effect of sulfur and thiobacillus in all studied attribute has known significant. The re effect of sulfur and vermicompost have known significant in all attributes exept of attribute of sulur in seed. The re effect of these 3 only in biological yield has known significant, also harvest index hasn,t known significant in this experiment as whole the result of this experiment indicante that the application of sulfur and thiobacillus, lonely or ure of both together, had positive effect in improving the specifics of growing, yield, soil pH and the mount of chickpea seed sulfur. Vermicompost had positive effect in the specifics of growing, yield and soil pH too.
