Abstract. Accumulation of heavy metals -Cadmium (Cd), Lead (Pb), Zinc (Zn), Copper (Cu) and Manganese (Mn) in root, stem and leaves of Indian mustard (Brassica juncea L.) grown on loamy coastal soil amended with different doses (100, 75, 50, 20, and 10 tha -1 ) of municipal solid waste compost was assessed during a period of 45 days. Heavy metal accumulation in root, stem and leaves of the plants were significantly different across different amendments and sole soil (P < 0.05). The ranking order of accumulated and translocated concentration of the heavy metals was Pb > Zn > Cu > Cd > Mn in the roots, which changed to Mn > Pb > Zn > Cd > Cu in the stem and to Mn > Pb > Cd > Zn > Cu in the leaves of the plants. The ranking order of heavy metal accumulation in different parts of the plant was root>stem>leaves for Pb, Zn, Cu and Cd; however, it was stem>leaves>root for Mn across all the treatments. The accumulation of the metals increased gradually and significantly with the passage of time in days from 15 to 45 days (p < 0.05).
