Re-vegetation of plant species using industrial and municipal wastewater and alternate bio-saline approach to grow salt tolerant plant species on salt affected soils may help to lessen the burden on fresh water source being used for irrigation. In this study, response of Acacia nilotica to combined stress of municipal wastewater and salinity was evaluated in pots conducted during 2007. Treatments comprised of four salinity levels i.e., control, electrical conductivity (EC) 6, 9 and 12 dS m-1 and three water types i.e., wastewater, tap water and mixed water (Waste & Tap water with ratio of 1:1). Mixing of wastewater with tap water was found the best for the better growth of A. nilotica at control salinity level. Shoot and root length, fresh and dry weights were reduced with increasing salinity. Maximum reduction of these parameters was recorded at highest salinity level (EC 12 dS m-1).
