    The present study focuses on phytoremediation potential of coriander and fenugreek plants in using contaminated soil collected from the Yamuna river bank. Accumulation of metals, viz. Cu, Pb, Zn, in plant parts in shoots and roots was analyzed. Coriander and fenugreek are well known hyperaccumulator plants. The presence of high concentration of metals led to reduction in soil organic contents. The pH value of the control soil was significantly (p<0.05) than that of the treated samples. Soil respiration and soil dehydrogenase were significantly (p<0.05) declined in treated soil. However, there was no significant variation (p>0.05) in organic carbon content in control and treated pots. Nitrogen, phosphorus and potassium were also reduced significantly (p<0.05) in treated soil. Heavy metal analyses using Atomic Absorption Spectrophotometer in shoots revealed that Cu was found higher in shoots of coriander grown in treated soil than in fenugreek plants grown with coriander in the same pot in control soil. Zn was found higher in shoots of fenugreek grown in treated soil and lower in coriander shoots grown in control soil. In roots Cu concentrations was found higher in roots of coriander plants grown in treated soil and Pb and zinc were in higher concentrations in the roots of fenugreek plants grown in treated soil. Cu registered minimum accumulation in fenugreek plants grown in control soil whereas Pb and Zn had minimum values of accumulation in coriander plant grown with fenugreek in control soil. However, there was no significant variation (p>0.05) in Pb for shoots and roots in all treatments.
