Abstract In recent years, using wastewater, such as fish farming effluent, has been increased, especially in developing countries. Therefore, this research aimed to investigate the effect of three types of irrigation water including river water, fish farm water, and mixed water (50% river water ? 50% fish farm effluent) on growth rates and concentrations of macro- and micronutrients in basil and purslane. The experiment was conducted in a randomized complete block design with three replications. Results indicated that irrigation with fish farm effluent significantly increased the fresh and dry weight of shoot and root, leaf number, and stem height in both plants. In the fish farm treatment, the fresh weight of shoots increased 203% and 250% compared to river water irrigation, in basil and purslane, respectively. Concentrations of N, P, K, Cu, and Mn in basil increased significantly in fish farm treatment compared to river water irrigation. Also, concentrations of N, P, Mg, and Cu in purslane increased in fish water treatment. In both plants, river water irrigation significantly enhanced Ca and Zn concentrations. Therefore, using fish farm effluent in irrigation provides water requirement of plants and also can improve the availability of nutrient elements for basil and purslane.
Significance Statement Due to water shortages, new sources of irrigation are needed. The plants used in this study have a high value for medicines and nutrition. Therefore, the findings of this research are applicable to the pharmaceutical and agricultural industries. & Azam Jafari [email protected] 1

Introduction Increasing population enhanced the production of wastewater; therefore, irrigation with wastewater is increasing in many developing countries, and agriculture is dependent on this water in many areas [1]. A large part of the world’s irrigated areas is located in developing countries, and the use of wastewater is not limited to arid and semiarid regions. One of the most important positive effects of using wastewater is the reduction in agricultural cost. This type of water is usable throughout the year and has no access restrictions [2, 3]. Also, due to the severe shortage of water, it is necessary to search for new water resources, such as wastewater [4] and fish farm effluent [1, 5]. The fish processing industry is characterized by the high volume of water used in the production stages and consequently the generat
