ABSTRACT

Zinc is an essential mineral element for the growth of plants which plays an important role in various enzymatic reactions, metabolic processes and oxidation reduction reactions when available in small concentrations. Excess concentrations of it can affect adversely on plants. Heavy metal pollution, due to disposal of sewage sludge is a widespread problem and is a risk for humans, animals and agricultural crops. Zinc phytotoxicity is reported relatively often, especially for acid and heavily sludge soils. Plants also respond to this heavy metal toxicity in various ways. Sometimes plants also used to remove this heavy metals from the soil. Present study was aimed to analyze the Zn absorbing capacity of groundnut plant and the impact of Zn on plant’s growth and biomass. Distinct 8 concentrations of Zn were applied in the soil and the growth of plants were observed.
