This study is to apply the Oryza model to simulate the rice yield, as the basic combine remote sensing image for the result is mapping yield in Soc Trang province. Weather data, crop management, water management and fertilizers uses data are also collected as data sources for the model. The yields observation was also collected in order to evaluate the result simulation of the Oryza2000 model. The results showed that the rice yield simulated from Oryza2000 model has very close correlation with field conditions for Winter-Spring and Summer-Autumn rice seasons, (r = 0,77 and r = 0,84) while there was no correlation for Spring-Summer season, it can be due to water regime and soil salinity constraints in this season.
