%X Heavy metal contamination leads to variety of harmful effects on soil and plant characteristics. In order to reduce the toxic effects of such substances, an experiment was conducted by FYM, N, NPK, FYM + NPK and FYM + N amendments in the soil from an area irrigated by waste water for more than 20 years. Soil and plant characteristics were compared between fertilizer (FYM, NPK, N and FYM + N, FYM + NPK) amended and non-amended control soil. As compared to the control, plants under FYM and FYM + NPK amendments showed lower accumulation of heavy metals and higher yield. Plants grown in NPK and N amended soil showed higher concentrations of heavy metals and lower yield compared to the control. Higher uptake of heavy metals in plants under NPK and N amendments, led to increase in the antioxidants enzymes, but reductions in photosynthesis rate, growth and yield. The results suggest that the application of FYM alone and in combination with inorganic fertilizers may be recommended as cost effective technique for reducing the availability of heavy metals in waste water irrigated soil.
