An Evaluation of the Effect of Treatment with Mixture of Cadmium and Lead on the Growth of Okra [Abelmoschus esculentus (L.) Moench]
Abelmoschus esculentus (L.) Moench was grown from seeds in soil polluted with a mixture of cadmium and lead in the ratio 1:1. The experiment consisted of control and four treatments (25, 50, 75 and 100 mg/kg) in three replicates. Data for growth parameters (seedling emergence, plant height, number of leaves, leaf loss, leaf area, and stem girth) were collected weekly for 3 months and number of flowers and fruits later in the experiment. The research lasted for 5 months. Physico-chemical and heavy metal analysis were carried out on soil samples at the end of the experiment.
