Abstract The
survival, biomass production and copper (Cu) remediation efficiency of Jatropha curcas
L. was evaluated in Cu rich industrial wasteland soil (IWLS), collected from
a local town, Sandila (Hardoi),
Uttar Pradesh, India. The IWLS had high bulk density, water holding capacity
(WHC), pH, electrical conductivity (EC), organic carbon and NPK. The Cu and Mn contents in IWLS were about 3 and 2 fold higher than
that in the normal field soil (control). Stem cuttings of the J. curcas clones (BTP-A, BTP-N and BTP-K) were planted
in IWLS? as
well as the same amended with cowdung or sand. The
percent survival, net elongations and biomass accumulation of J. curcas were decreased slightly in IWLS, as compared
to the control soil.? The translocation
of Cu from soil to the plants was higher in IWLS grown plants, which was more
pronounced in IWLS amended with cowdung. J. curcas clones BTP-N, showed better survival and Cu
removal efficiency from IWLS. Key
words Bioaccumulation,
Copper toxicity, Industrial wasteland, Jatropha
