Germination, early seedling growth and chlorophyll contents of Abelmoschus esculentus L. Moench under varying concentrations of aluminium sulphate (alum) treated surface-runoff were investigated in the laboratory. The concentration levels of 0, 10, 20, 30, 40 and 50 % of aluminium sulphate were used. Aluminium sulphate treated surface-runoff significantly (P < 0.05) decreased the percentage germination of the crop. Treatments with aluminium sulphate significantly (P < 0.05) decreased the shoot length, root length, fresh weight, dry weight and moisture content of Abelmoschus esculentus relative to the control.
