Growth of crop plants is suggested to be inhibited by elevated concentrations of heavy metals in soils. This research was to evaluate the effects of heavy-metal-containing industrial waste on growth of amaranth in two tropical soils treated with lime and/or cassava-leaf compost. Soils with low and high adsorption capacities to heavy metals were used. Soil samples were factorially treated with wastes (Control, Model Waste 1 i.e. a mixture ofstandard solution to increase the concentrations ofCu, Zn, and Pb, respectively. and Cd 5 and MW 2, i.e. 4 times MW 1,. and industrial waste ofmetal-spoon industry at 20 and 80 ton ha-1), lime (at 0, 2.5 and 5 ton.ha-1), and cassava-leaf compost (at 0, 5,, and 1O ton ha-1). Soil mixtures were then cultured toamaranth for four weeks in a greenhouse experiment. The growth of amaranth in both soils was inhibited by the model waste. Unlike in Gedongmeneng soil, the negative effect of the model waste in Banjaragung (high adsorption capacity) was alleviated by lime and/or cassava-leaf compost additions. Conversely, industrial waste addition tended to increase the growth of amaranth in Banjaragung soil even though this effect tended to decrease with lime addition. This effect was not observed in Gedongmeneng soil.
