An experiment was conducted to evaluate the growth and yield characteristics of Capsicum chinense (Tourn) grown on soil affected by effluent discharge from Iron and steel company. Seeds of Capsicum chinense Tourn. collected from Osun State Control Development Project Office, Modakeke were broadcasted in a plastic bowl of 60 cm diameter and 20 cm height that contained top soil. The seedlings were grown for a period of four weeks in the nursery bed after which they were transplanted into 50 plastic pots containing regrowth forest soil and effluent discharged soil. Capsicum chinense seedlings were established at varying density (one, two, three, four and five) with each density having ten replicates for both soil samples. Data were collected on the following growth parameters; the number of leaves, leaf area, shoot height, petiole length, stem dry weight, root dry weight, leaves dry weight and fruit dry weight. The data obtained from this study were subjected to appropriate statistical analysis. The chemical analysis of the two soil samples showed that effluent discharged soil had higher organic carbon contents (2.9 mg/kg), higher amount of nitrogen (0.92 mg/kg), phosphorus (17.81 mg/kg), potassium (19.5 cmol/kg), lead (22.82 mg/kg), cadmium (2.49 mg/kg), and copper (10.3mg/kg) when compared to control soil. Among the growth parameters studied, soil condition had significant effect on the total number of leaves (82.32) at P<0.05. It can be concluded that at low concentration, industrial effluent in soil produced desirable and better growth characteristics and crop yield. It also improve the soil properties by improving the soil nutrient status especially the soil organic matter. Keywords: Environment, Global, Re-growth, Degradation, Waste.
