The present study evaluated the effect of mining effluent contaminated soil treated with fertilizers on growth parameters, chlorophyll content and proximate composition of Cucurbita pepo. Effluents of Crush rock, Crush stone and Ezza quarry sites in Ishiagu, Ebonyi State Nigeria were used for the study. Soil samples including the control were treated with urea fertilizer (sample E), NPK 20.10.10 (sample F), while sample D was without fertilizer. Results showed that plants treated with urea fertilizer showed significant increase (p<0.05) in all the parameters evaluated when compared with other treatments and are in the order E>F>D. Results suggest that mining effluent impacted negatively on growth, chlorophyll and proximate composition of Cucurbita pepo vegetable.
