摘要：Due to scarcity of water globally, wastewater has been become alternative source of water for irrigation to minimize the pressure of fresh water demand. Therefore, aim of the present study was to investigate the in^uence of wastewater on the performance of Melia azedarach L. grown for three consecutive years. The pooled data of three years reveal that wastewater irrigation markedly increased plant height, stem diameter, leaf area, fiber length, leaf fresh weight, Leaf dry weight, stem fresh weight, stem dry weight, root fresh weight and root dry weight except specific gravity as compared to the tap water irrigation. Also, plant irrigated with wastewater exhibited higher concentration of nutrients (nitrogen, phosphorus and potassium). Although, continuous irrigation of plants with wastewater may cause heavy metal accumulation, (especially by lead, cadmium and nickel). The use of wastewater for irrigation of Melia azedarach might be an important and alternative source of water and nutrients for better growth and development of tree plant.
