<![CDATA[Clay is one of the main raw materials used in cement production and is obtained through mining activities. Such mining activities can cause land degradation, including a reduction in soil pH. Land rehabilitation can be carried out by using acid-tolerant plants, applying land engineering techniques, and introducing mycorrhizae. This study aimed to determine the effects of various planting-media treatments on the growth of Jatropha curcas and to identify the optimal land-engineering treatment for its growth. The planting-media treatments consisted of combinations of garden soil, post-mining soil, and mycorrhizae. Each planting-media treatment was replicated four times and observed for 12 weeks (60 days after planting). Plant growth parameters included plant height, number of leaves, leaf area, plant biomass, shoot-to-root ratio, transpiration rate, net assimilation rate, and mycorrhizal infection. The data were analyzed using one-way ANOVA, followed by a Tukey post-hoc test. The results showed that increasing the proportion of post-mining soil resulted in lower growth of Jatropha curcas. The best growth of Jatropha curcas was observed in the treatment consisting of 50% post-mining soil + 50% garden soil + mycorrhizae. Mycorrhizal infection was inversely related to the proportion of post-mining soil. As the proportion of post-mining soil increased, the level of mycorrhizal infection in Jatropha curcas decreased]]>
