Biofrtilizers as an alternative and in most cases as a supplement to chemical fertilizers can improve plant growth and physiological processes. They are also considered as one of the most nathral ways to keep vital soil system alive and active. In this regard to detarmine the effects of drought stress on millet and vermicompost on some traits of experimental millet as a factorial split plot based on randomaized complete block with 3 replications. Exprimental variables inclodingdrought stress at two levels of control and irrigation interruption at the time of emergence of the cluster were considerd as the main factors. The sub- factors were respectivly: millet cultivars in two kinds of Bastan and Pishahang, vermicompost in two levels of non use and 30 ton/ha fertilizer. Acording to the results, drought strees reduced traits such as 1000-grain weight and biological yield. The vanguard cultivar was more suitable than the ancient one and was favorable for cultivation. Vermicompost inceased grain number per panicel, grain yeild and biological and cholorophyll content. Due to less weight loss of a thousand seeds in Pishahang cultivar than in Bastan under drought stress, this cultivar was more drought resistant and is more suitable for cultivation under water shortage conditions.
