A pot experiment was conducted to find out the effect of application amounts of silicates on the fatty acid and sterol composition of paddy rice at various growing stages. The results obtained were as follows; 1. At maximum tillering stage and heading stage, significant positive correlations were obtained between the ratio of unsaturated fatty acid to saturated fatty acid and silica absorption, dry matter or grain yield, respectively. But significant correlation was not observed between them at harvesting time. 2. At maximum tillering stage and heading stage, the ratio of unsaturated fatty acid to saturated fatty acid in paddy rice was increased with increasing silica application from 80 to 180 ppm of soil, but these ratio was decreased at the plot of 200Kg/10a of silicate. 3. The ratio of sitosterol to stigmasterol in paddy rice at maximum tillering stage was increased with increasing silica application of soil, but these ratio was increased with increasing silica application up to 180 ppm of soil at heading stage, and was decreased at the plot of 200Kg/10a (410 ppm in soil) application of silicates.
