Avaluable product that sewage sludge contains in organic matter and nutrients, has become an important problem with negative effects on the environment. The effect of sewage sludge applied in four different doses to soil as 0 %, 20 %, 40 %, 60 % respectivly on the growth, yield and flower quality of Rosa canina 'Laxa' grafted on Rosa sp. "Akito" were investigated. The results associated with plant growth, yield and quality parameters indicated that shoot and root fresh and dry weight per plant, root lenght of plant, flower number per plant, flower body lenght and width, Bud lenght and width increased by the application of sewage sludge. The maximum values for the parameters were observed in media containing % 40 sewage sludge but with more increasing sewage sludge dosage, all parameters a decreasing trend became apparent. Thus it is suggested that sewage sludge and soil mix may be further exploited as a standard potting media and that the addition of 60 % or more sewage sludge to potting media is not recommended for cut roses.
