Abstract: The effect of different concentrations of treated wastewater (0, 25, 50, 75 and 100%) on growth performance and metals accumulation of two lines of Guar (Cyamopsis tetragonoloba) seedling (L18 and L53), under nursery conditions were investigated. The experiment was conducted using a completely randomized design with three replicates.. Plant height, leaves number, fresh weight and dry weight were measured after 60 days. Besides, the concentration of copper, manganese, zinc, chromium and nickel were determined for both stem and leaves of the tested lines. The results indicated that the development of both lines was significantly affected by the application of wastewater. However the concentration of metals was of no consistent pattern in leaves and stem of both lines. The results demonstrate that the ability of plant lines to accumulate metals as observed depends on wastewater concentration and the type of metal. These results suggest that using treated wastewater at different concentration will benefit and not harm Guar plant; however, the greater growth will be achieved with 100% concentration of the treated wastewater.
