The limitation of water resources has drawn the attention of researchers to the basic use of non-conventional waters such as salt water and municipal and industrial wastewater. Due to the high value of healthy fresh water, wastewater reuse is an efficient option for managing water consumption. To investigate the effects of irrigation with treated wastewater and foliar application of iron fertilizer on the morphophysiological characteristics of geranium, an experiment was conducted in a factorial design within a completely randomized framework with two factors and three replications in a research greenhouse located in Mashhad in the year 1400 (2021-2022). The first factor included two types of irrigation sources (well water and irrigation with wastewater), while the second factor pertained to the foliar application of iron fertilizer, which was examined at three levels: zero, 3, and 6 grams per liter (in the forms of iron chelate and nano iron chelate). The results showed that the effect of fertilizer and type of irrigation water on the assessed traits except for anthocyanin was significant at the probability level of 1%. Comparison of the average effect of fertilizer and irrigation on traits showed that the highest plant height, stem diameter, number of lateral branches, dry weight, proline and carotenoid were observed in iron nano chelate fertilizer and irrigation with wastewater. The use of nano-iron chelates increased the dry weight of the plant by 23% compared to the use of iron chelate in irrigation with wastewater, irrigation with normal water and the use of iron chelate fertilizer was ranked next. The results of the investigation showed that, unlike water stress, urban wastewater not only does not have a harmful effect on the growth and development of geranium, but its use as a soluble fertilizer is recommended for use in green spaces for optimal use of water.
