A pot experiment was conducted to find out the effects of phosphorus on the retardation of cadmium uptake by rice plant using the soil with 8.8 ppm of available phosphorous. Soils were treated with cadmium concentrations of 3, 6, 9 ppm and phosphorus amounts of 10, 20, 40 kg/10a respectively. The results were summarized as follows; There was no correlation between cadmium and phosphorus content in the rice plant. Even though the greater amounts of cadmium were absorbed and translocated to the brown rice and the leaves, the cadmium contents between brown rice and leaves were positively correlated. In soil which contained 3, 6, 9 ppm cadmium ranges, phosphorus was applied 13, 17.6 and 27.6 kg/10a respectively, and so the cadmium content fell below 0.4 ppm in the brown rice. The growth and yield of rice plant were normal in soils with cadmi0950um content below 9
