ABSTRACT
A study was conducted to determine the effects of cadmium and lead on Glycine max at different concentrations. The experiment was carried out with four treatments and one control with four replicates per treatment. The soil was treated with Cadmium (Cd (NO3)4H2O) and Lead nitrate Pb (NO3) in the following proportion; 50mg/kg, 100mg/kg, 150mg/kg, 200mg/kg and control. Each bag was filled with 5kg of soil and the bags were perforated to allow for drainage. The seeds were planted at a depth of 3cm. Five seeds were planted per planting bag in order to carry out germination studies. Germination study was conducted for six days and at the end of the study, control, 50mg/kg, 100mg/kg, 150mg/kg and 200mg/kg were 46.67±11.55, 80.00±20.00, 66.67 ±11.55, 31.67±10.41 and 12.33±5.78 percent respectively. Other growth indices recorded were plant height, stem girth, number of leaves and number of branches were recorded after seven days. At the end of the experiment, values recorded for plant height for the various treatments (0, 50, 100, 150 and 200 mg/kg) were 19.62±8.19cm, 32.75±4.03cm, 34.43±3.59cm, 25.18±2.14cm and 31.00±3.18cm respectively.
