1. Increasing the levels of applied Cd or Pb significantly decreased the dry matter yield of shoots, roots and whole plants for both red radish and kenaf, under with or without addition of soil amendments, but the values under addition of soil amendments were still higher than that of without addition.2. The adverse effect of Cd or Pb on plant growth of red radish was much more pronounced in roots than in shoots, while the adverse effect of Cd or Pb on plant growth of kenaf plants was much more pronounced in shoots than in roots. However, the adverse effect of Cd or Pb on plant growth was much more pronounced in red radish than in kenaf plants.3. Application of soil amendments under Cd or Pb levels increased the dry matter yield of red radish and kenaf shoots, roots and whole plants as compared with no application. The highest increases were obtained with the application of compost, while the lowest increases were obtained with Zn-EDTA treatment. The efficiency of the added soil amendments in increasing red radish and kenaf yields of shoots, roots and whole plants could be arranged as follows: compost < gypsum < liming < Fe-EDDHA < Zn-EDTA.4. Increasing the levels of applied Cd up to 15 mg kg-1 soil and Pb up to 300 mg kg-1 soil significantly increased Cd or Pb content and uptake by shoots and roots for both two plants, under with or without addition of soil amendments, but the values of Cd or Pb content under addition of soil amendments were lower than that of without addition.5. The content and uptake of Cd or Pb by shoots and roots for both plants significantly decreased with addition of any soil amendments. The highest decreases were obtained with the application of compost, while the lowest decreases were obtained with Zn-EDTA treatment.6. The content and uptake of Cd or Pb by red radish was much more pronounced in roots and shoots than that in kenaf plants. Also, most of Cd or Pb taken up by red radish plants was retained in the roots and consequently less Cd or Pb transported to the shoots. However, the content and uptake of Cd or Pb by shoots of kenaf plants was higher than by roots, indicating the ability of plants to transport more Cd or Pb to the shoots and consequently minimize the adverse effect of Cd or Pb on root growth.7. Application of soil amendments, except liming, decreased soil pH under all levels of applied Cd or Pb comparing with un-amended soil. There were slightly differences among the pH. Zn-EDTA application gave the lowest pH values whereas liming gave the highest pH values.8. The values of pH obtained under the kenaf plants slightly increased than obtained under red radish plants, mainly attributed to the plant species and its root exudates.9. The highest values of total, available and availability index of Cd or Pb in soil were pronounced at the highest concentration of Cd or Pb under all the studied soil amendments compared with the unamended one. On the other hand, the used soil amendments led to a significant decrease in available and availability index of Cd or Pb, as compared with the unamended one, being organic compost was the best soil amendments.10. The amount of available and availability index of Cd or Pb after harvesting of red radish plants was lower than that after harvesting of kenaf plants, and in turn reflected on plant uptake.
