The concentrations of ID, N, and P were optimized (0.1 mL·L<sup>-1</sup>, 7 mM, and 2.5 mM, respectively) and they were applied in various combinations to the contaminated soils of potted plants of <em>J. curcas</em>. The results showed that ID together with the N and P fertilizers, increased plant biomass and improved the mitigating effects of the N-P treatments on Cd and Pb toxicity. Plants growing under ID-N-IP treatments had high whole plant biomasses, high concentrations of P, N, Pb and Cd in whole plants, as well as enhanced activities of superoxide dismutase (SOD) and peroxidase (POD). These results point to the phytoremediation ability of <em>J. curcas</em>. We propose a new methodology that can be utilized to study the effects and interactions of multiple factors on plant growth.</p><p><a href="https://doi.org/10.2298/ABS190216050F">https://doi.org/10.2298/ABS190216050F</a></p><p><strong>Received:</strong> February 16, 2019; <strong>Revised:</strong> August 17, 2019; <strong>Accepted:</strong> August 19, 2019; <strong>Published online:</strong> August 30, 2019</p><p><strong>How to cite this article:</strong> Fang Z, Wan H, Xu Y, Liu Q, Liang J, Shi X, Chen F.
