Abstract: In modern agricultural research, crop modelling has become a critical tool which incorporates scientists’ insights into the physiological and ecological processes by conducting crop growth into mathematical equations. The crop simulation models have been shown to be efficient in assessing the relationships between crop yield and environmental factors. They are able to determine the response of crop plants to change in weather. This study compares six different crop simulation models, namely RICEMOD, CERES-Rice, MACROS, RICESYS, SIMRIW and ORYZA series which can be used to evaluate the impacts of climate change on rice production. Comments are then made about the application and usefulness of these models.
