The proposed study distributes a questionnaire consists of 37 questions among some management team of Agricultural ministry in one of the provinces of Iran. The main hypothesis of this survey examines the positive relationship between leadership style and perceived organizational effectiveness. The other hypothesis is associated with the supportive leadership style and perceived organization effectiveness and the third question is associated with democratic leadership style and perceived organization effectiveness. The results of Spearman-Pearson test confirm all three results, which indicate there is a meaningful and positive relationship between leadership style and perceived organizational effectiveness.
