Agave americana was evaluated for its tolerance to different levels of Cr (0, 25, 50, 100 and 200 mg kg−1 soil) and its suitability for the remediation of Cr contaminated sites. The pot culture experiment was carried out for 3 months in clay soil which was collected from 0 to 30 cm depth from the nearby agricultural field. The partitioning of Cr between roots and shoots and its uptake by the plant, bio-concentration factor, translocation factor, translocation efficiency etc. were used to determine the remediation potential of the crop. Overall, the plant could tolerate up to 200 mg Cr kg−1 soil, but a concentration of 81 mg Cr kg−1 soil caused a reduction in the dry weight of the plant by 50 %. The highest total uptake of Cr (2286 µg g−1 plant) and bio-concentration factor (6.59) was found at Cr 200 mg kg soil−1. However, the translocation factor values were found to be
