Abstract

The present research on plants efficacy for phytoextraction of metals was conducted at the Division of Soil Science and Agricultural Chemistry, Indian Agricultural Research Institute, New Delhi. This study envisages the efficacy of plants, information about heavy metal removal efficiency and their specificity. Correspondingly identify efficient suitable plants for remediation of heavy metals from polluted soils. A greenhouse pot experiment consisted of surface soil sample was collected from Godwa village, Udaipur district, Rajasthan and four crops i.e. mustard, sunflower, guinea grass, napier grass which were replicated five times in a completely randomised design (CRD). This soil mainly contaminated with lead and cadmium heavy metals. The crops were harvested at maximum vegetative growth stage and post-harvest soil was used for further chemical analysis. Lead content in crop shoot were 2.08, 1.26, 0.82 and 0.66 mg kg-1 and cadmium were 3.25, 2.42, 1.81 and 1.64 mg kg-1 in mustard, sunflower, napier grass and guinea grass, respectively. While in crop root total lead content were 0.85, 0.70, 0.58 and 0.49 mg kg-1 and cadmium were 0.70, 0.59, 0.50 and 0.41 mg kg-1 in mustard, sunflower, napier grass and guinea grass, respectively. The study revealed that mustard and sunflower are significantly superior overnapier grass and guinea grass. Therefore, both mustard and sunflower having ability to accumulate more amounts of lead and cadmium in its shoot and roots.

Conclusion

The present study conducted to find about the efficacy of plants, heavy metal removal efficiency and their specificity. Present investigation concluded that both mustard and sunflower having ability to accumulate more amounts of lead and cadmium in its shoot and roots. Out of four crops mustard and sunflower are significantly superior over napier grass and guinea grass having ability to accumulate more amount of cadmium and lead in shoots and roots tissues. Therefore, mustard and sunflower selected out of four crops based on results of phytoextraction of metals.
