A pot experiment was conducted to find out the effects of water management and application of slaked lime and wollastonite on Pb uptake of rice in a Pb added soil. The soil was adjusted to 0, 150, 300 and 600 ppm of Pb concentration. The slake lime was applied at the equivalent amount of lime requirement with 150 kg/10a adding and the wollastonite, 200 kg/10a, respectively. The lead contents in leaf stem and brown rice increased with increasing the soil Pb content and the ratio of Pb/(Ca + Mg) equivalent in soil but they showed no influence on yields.
