Abstract: The African marigold (Tagetes erecta L.) was grown in cadmium-stressed soil, with and without Glomus mosseae, to examine the effect of fungus on plant growth and cadmium uptake from the contaminated soil in greenhouse conditions. It was concluded from the study that arbuscular mycorrhiza (AM) inoculation has significantly increased plant growth, cadmium uptake, and bioremediation of cadmium from the soil. The accumulation of cadmium in the African marigold plants was found to be significant in the treatments with AM inoculation when compared with control (uninoculated) plants at different cadmium concentrations (0, 5, 10, 25, 50, 100 ppm). The results proved that the African marigold with Glomus mosseae can be a potential candidate in reducing environmental pollution and in the sustainable ecological restoration of cadmium contaminated sites.
