The work was carried out at the Experimental Farm of El-Kassassin Horticulture Research Station, Horticulture Research Institute to study the effects of various sewage sludge application rates (0, 10%, 20%, 30% and 40%) on growth and Cd, Pb and Ni content in the roots, stems and leaves of two Eucalyptus species, Eucalyptus citriodora and E gomphocephala . Also, to study the possibility of using specific transplants for bioaccumulation some heavy metals on new reclaimed soils in semi arid areas using treated municipal sewage sludge. The highest value of plant height and stem diameter obtained from Eucalyptus gomphocephala with 30% or 40% of sewage sludge application. High amount of Ni was observed in leaves of the studied plants
