Research Abstract	Silicon contributes to various stress tolerance of plants. In this study, effects of silica application to the maintenance of yield under drought condition were examined. In cucumber, which deposit silicon in bloom(white powder-like structure on fruit surface), silica application positively reduced the mortality rate of fruit under drought, and as the result, improved the yield. But in soybean, which is also accumulate silicon, did not respond to silica application under drought.
