Abstract A growth model-based decision support system for crop management (GMDSSCM) was developed, which integrates process-based models of four different crops—wheat, rice, rape and cotton—and realized decision support function, thus facilitating the simulation and application of the crop models for different purposes. The individual models include six sub models for simulating phase development, organ formation, biomass production, yield and quality formation, soil-crop water relations and nutrient (N, P, K) balance. The implemented system can be used for evaluating individual and comprehensive management strategies based on the results of crop growth simulation under various environments and different genotypes. A stand-alone edition (GMDSSCMA) was established on VC++ and VB platforms by adopting the characteristics of object-oriented and component-based software and with the effective integration and coupling of the growth prediction and decision-making functions. A web-based system (GMDSSCMW) was then further developed on the .net platform using C# language. These GMDSSCM systems have realized dynamic prediction of crop growth and decision making on cultural management, and thus should be helpful for the construction and application of informational and digital farming system.
