COMPARATIVE STUDY OF GROWTH AND SURVIVAL RATE OF JATROPHA CURCAS CLONES (BTP-A, BTP-N AND BTP-K) IN THE CONTAMINATED WASTELAND SOIL FROM SANDILA INDUSTRIAL AREA (SIA)

摘要

A short term experiment of 25d was carried out to evaluate the survival and growth rate of 3 clones of Jatropha curcas viz. BTP-A, BTP-N and BTP-K in the contaminated wasteland soil collected from Sandila Industrial Area (SIA), amended with 40% sand and 40% cow dung. Although, contaminated wasteland soil alone and in combination with 40% sand and 40% cowdung promoted the survival rate and enhanced the growth of the plants, but the amendment of contaminated wasteland soil with 40% cowdung significantly improved the growth of plants, as compared to the other amendments. In addition, high nitrate content was also observed in the fresh and dry biomass of leaves, that ranged from 266 to 490 ug g1 and 94 to 174 ug g"1 respectively, at the end of experimental period. Though, all the 3 Jatropha curcas clones survived and grown well in all the amendments provided, but among them BTP-A was found to be potentially better adapted for contaminated soil, degraded soil or wasteland soil, suitably after amending with organic waste, and it may also be promoted for remediation of nitrate contaminated soil.
