| Research Abstract |
In this study, inverse estimation method of irrigation water supply was developed from rice yield data. The distributions of rice yield were evaluated by using the radiation spectral - rice yield relation curves. Water stress of paddy rice was calculated by using plant growth model from meteorological data, and irrigated water was estimated by using soil water balance model considering the effect of ground water.
