Abstract
The aim of present study was to remediate chromium Crcontaminated soil by Crotalaria juncea in the presence of Pseudomonas fluorescens Inoculation of P fluorescens in pot soil grown with C juncea significantly increased ~2fold the watersoluble Ws and exchangeable Ex Cr contents in contaminated soil under greenhouse condition It also enhanced the chlorophyll content by 92 and plant biomass by 99 as compared to the uninoculated C juncea plant The analysis showed that root and shoot uptake of Cr in C juncea inoculated by P fluorescens was 308 and 282fold respectively This research showed that the association of C juncea and P fluorescens could be a promising technology for increasing the soil Cr bioavailability and plant growth for successful phytoextraction of Cr from the contaminated soil
