Evaluation of the APSIM model in cropping systems of Asia

Abstract. Climatic, institutional and social changes in many rice-growing regions of Asia are among challenges to increase food production whilst ensuring environmental sustainability. In this seminar, modelling studies using cropping systems model, the Agricultural Production Simulator (APSIM) are presented. The model ability to capture interactions between soil water and nutrient dynamics, crop growth, climate and farmer management was evaluated for cropping systems in Asia. The model performed well in simulating the diversity of cropping systems, with particular strengths in simulation of multi-crop sequences and specification of realistic dynamics in farmer management practices. Promising results were also obtained in using the model in combination with field experiments to identify water management strategies which could alleviate salt stress and improve water productivity for coastal zones.
