Abstract: The present study was carried out to evaluate the accumulation of heavy metals in soil and in paddy crop that have been amended by different dose of fly ash (20, 40, 60 t ha-1) with and without FYM. In this study, the amount of heavy metals (Ni, Co, Cr, Pb and Cd) present surface and subsurface soils and various parts of the rice plants was ascertained. Field experiment was conducted at Krishi Vigyan Kendra, Research Farm, Janjgir – Champa (C.G.) during kharif season 2016. The increasing doses of fly ash with and without FYM show increasing content of heavy metals in soil and plant parts. The occurrence of heavy metals in paddy field soils was in a decreasing order of Cr > Pb > Co >Ni> Cd while, in plant parts order of Ni > Cr > Co >Pb> Cd. The highest concentration of heavy metals in this study was in the roots rather than in the parts of the rice plant that were above the ground (grain, leaf and stem), except for Cd, which was present in significant amounts in the leaves. However, these concentrations of heavy metals in the soil and rice plant parts were still below the maximum permissible limits.
