This study was carried out to determine the effect of advanced biological treated domestic wastewater on the agronomic properties and nutritional content of some forage crops, as a result of the increasing interest in using treated wastewater in agriculture. The study of diluting biologically treated domestic wastewater with varying amounts of pure water 25%, 50%, and 75% pure water, and applied to crested wheatgrass (Agropyron cristatum Geartn), orchard grass (Dactylis glomerata L.) and alfalfa (Medicago sativa L.) at field capacity. The trial plants used were alfalfa, orchard grass, and crested wheatgrass. The application of the diluted wastewater influenced the height of all three plants. After the first cutting, both alfalfa and orchard grass had increased green and dry weights per pot, with the most significant increase observed in alfalfa. The application of wastewater resulted in an increase in nutrient and metal concentrations in all three plants. Additionally, the concentration of selenium decreased in alfalfa and crested wheatgrass. The diluted wastewater did not affect the calcium concentration in alfalfa. However, it had a positive effect on the relationship between orchard grass and all elements, except for selenium which had a negative effect. Moreover, the application of wastewater led to an increase in soil organic matter and electrical conductivity, while decreasing the pH with increasing wastewater ratio. Moreover, the application of wastewater led to an increase in soil organic matter and electrical conductivity, while decreasing the pH with increasing wastewater ratio. The concentration of nutrients and metals was significantly affected by the application of diluted domestic water. This was due to the increased uptake of plant elements, which in turn was associated with responses in soil organic matter and electrical conductivity. It may be advisable to conduct longterm field studies to determine the dilution rate at which the salinity risk threshold can be established.
