10.22376/ijpbs.2019.10.1.p1-12 Volume 9 Issue 2 2018 (April-June) The presence of metals in fly ash is well researched. In the present work the metal uptake including heavy metals from fly ash by biodiesel plant lessThan i greaterThan Jatropha curcas lessThan /i greaterThan was studied. For this study three samples of fly ash amended soil were prepared: Treatment 1- T lessThan sub greaterThan 1 lessThan /sub greaterThan (100% soil), Treatment 2- T lessThan sub greaterThan 2 lessThan /sub greaterThan (25% fly ash + 75% soil) and Treatment 3- T lessThan sub greaterThan 3 lessThan /sub greaterThan (50% fly ash + 50% soil), where sample size was 15 in all treatments. The biochemical and morphological parameters of lessThan i greaterThan J. curcas lessThan /i greaterThan were studied for three consecutive years of plant growth in all treatments. Among all treatments, T lessThan sub greaterThan 3 lessThan /sub greaterThan treatment plants showed better growth due to the presence of nitrogen 11.73mg/g, protein 62.08%, sulphur 0.15%, reducing sugar 1230.59µg/g, chlorophyll-a 0.52mg/g, chlorophyll-b 0.41mg/g, carotenoids 0.27mg/g, total chlorophyll 0.93mg/g in leaves. The percent absorption of metals (Zn, Ca, Mg, Pb, Cu, Fe, Mn, Ni and Cd) by lessThan i greaterThan J. curcas lessThan /i greaterThan plants were also taken in consideration by evaluating metal concentration in two stages. Correlation between plant growth and metal uptake was evaluated, which proved the significant effect of metal uptake on plant growth of lessThan i greaterThan J. curcas lessThan /i greaterThan from T lessThan sub greaterThan 1 lessThan /sub greaterThan to T lessThan sub greaterThan 3 lessThan /sub greaterThan . This research approaches the waste utilization and remediation of fly ash amended soil by accumulation of metals from base material.
