The use of natural processes such as phytoremediation is a suitable solution to reduce water and soil pollution. In this study, two separate experiments were conducted in the form of a 2019-2020 factorial experimental design in a greenhouse to investigate the effects of sewage leachate and industrial effluents on the growth characteristics of vetiver plant species. The experimental factors included leachate and industrial effluents at concentrations of 0%, 25%, 50%, 75%, and 100% in three replicates with two water use stress in 5 and 10 days. Characteristics evaluated included plant height, number of branches, fresh and dry weight of shoots, and fresh and dry weight of soil organs (roots). The results showed that irrigation with municipal wastewater leachate had a significant effect on the number of branches (P < 0.01), fresh weight, and dry weight of roots at a 5% level. The results of applying industrial wastewater had a significant effect on height, number of branches (P < 0.01), dry weight of vetiver, and fresh and dry weight of roots (P < 0.05), but no significant effect on fresh weight of vetiver (P > 0.05). The highest additive effect of industrial effluent and irrigation stress on plant morphological characteristics was obtained at the interaction level, W2A1 treatment (25% industrial effluent and 5 days irrigation stress). The results of this study showed that the use of waste leachate and industrial wastewater mixed with irrigation water to irrigate compatible vetiver species can be considered as a solution for the use of unconventional water in production.
