[ABSTRACT]In order to assess the fe asibility of developing an efficient su gar beet cultivation support system to effectively reduce the costs of beet cultivation, beet collection and sugar production using an agricultural spatial information, and also to predict the root yield_ of sugar beet three months before the harvesting season, an analysis of satellite data and meteorological data was carried out in this study. For predicting the root yield of sugar ・ beet, the analysis of th e grow th was conducted around the town of Memuro, Hokkaido, Japan. The cumulative temperature (T), cumulative rainfall (P) and cumulative solar radiation (R) from the end of April to the middle of July were selected as the predictors of the root yield (RY) prediction formula. RY=0.043675R+0.02783T-1.09513P-39.634(r2=0.87**) The predictive error was 3. 8t/ha, that was the resu It calculated by the farmers group, after weighted to the predicted root yield using NDVI which was derived from SPOTS satellite data. The results suggest that it was possible to predict the root yield before three months of harvesting season. By providing sue h result to sugar companies in m uch earlier before harvesting, the sugar beet collection and sugar production efficiency will be increased.
