Cumin (Cuminum cyminum) is one of the important aromatic plants that can be planted in arid and semi-arid areas. Since, the most of areas in our country (Iran) deal with water deficiency, any study helping water optimum application is useful. In this study, effects of water stress on cumin product were investigated. Treatments consisted of moisture limits in FC, 2/3FC, and 1/3 FC. Investigated traits, were seed yield, one thousand seed weight, number of umbel per plant, stem weight, root weight, and stem/root weight ratio. Experimental design was a RCBD with 4 replications. ANOVA results showed that the effect of the treatments on seed yield, one thousand seed weight, number of umbel per plant, and stem weight were significant (alfa<0.01), but not on root weight, and stem/root weight ratio. According to result of Duncan test Fc treatment showed significant differences for umbelper plant and stem weight (alfa<0.05), while other treatments level were no significant. Results of Pearson correlation coefficient showed that there were significant correlations among all of the traits (alfa-ʹ<0.01). According to the results of this study, to achieve maximum yield, cumin must be supported with sufficient moisture.
