| Abstract | Crop growth simulation models provide a means to quantify the effects of climate, soil and management on crop growth, productivity and sustainability of agricultural production. These tools can reduce the need for expensive and time-consuming field experimentation as they can be used to extrapolate the results of research conducted in one season or location to other seasons, locations, or management. The development and application of system approaches and decision support methods can help to identify strategies for optimising resource use, increasing productivity, identifying yield gaps and reducing adverse environmental impacts. The DSSAT (Decision Support Systems for Agro-technology Transfer) software facilitates the application of the various crop models. CSM-CERES-Rice, embedded within DSSAT, is a process-based, management-oriented model which simulates the growth and development of rice. The MERES (Methane Emission from Rice EcoSystems) model is a further development of CERES-Rice with additional processes for methane emission from rice fields. The objectives of the present study were to: · evaluate CSM-CERES-Rice ver. 4.0 for its ability to simulate rice growth and yield · estimate potential yield and yield gaps in rice · estimate and improve understanding of water and N dynamics and balances in the continuously flooded, continuously saturated and intermittently irrigated rice culture · demonstrate potential applications of the model to improve understanding of sustainability issues related to water and N in various rice culture · evaluate the ability of MERES to predict methane emission from rice culture in northwest India | |
