Abstract: Parthenium density and species richness were found to be more in non-invaded (N-I) sites as compared to invaded (I) sites of Jaunpur district. pH, OC and %N of the soil indicates that the plant survive naturally at higher level of salinity. In pot experiment, plant growth, proline content, TSS content, chlorophyll, N, P and K was not significantly affected up to 1% NaCl (w/w) over the control after 30 and 60DAS. BCF for parthenium plant was >1 up to 2% NaCl treatment. Bacterial population was more in rhizospheric soil then rhizoplane soil under NaCl after 30 and 60DAS, and indicates bacterial-rhizoadaptation. Hence, the parthenium plant able to improve soil health and might be useful in the field of restoration ecology.
