Canegro is one of the leading sugarcane crop growth models and has been used extensively in research and management. An early version of Canegro was included as part of version 3.5 of the Decision Support System for Agrotechnology Transfer (DSSAT), an international modelling platform. Subsequent amdndments by different research groups resulted in different Canegro versions that were never integrated, nor incorporated, into DSSAT. Sinultaneously, DSSAT (Version 4.0) adopted a modular structure, and many utilities were added, such as a powerful graphical user interface allowing non-experts to set up, run and analyse simulations; improvements that were not available to Canegro users. The International Consortium for Sugarcane Modelling (ICSM), established by leading sugarcane industries and research groups, recognised this problem and launched a prlject to incorporate an up-to-date version of Canegro into DSSAT v4. SAsRI-Canegro ws taken as the starting point. The project entails: (i) restructing the current Canegro code to the DSSAT v4 input/output framework and the generic modules for management, soil, weather and the energy balance, (ii) verification of model results against the current version of Canegro into DSSAT predetermined set of simulation runs; (iii): sensitivity analysis on key processes, such as canopy development, crop water uptake, biomass accumulation and partitioning, to changes in soil, weather, management and variety traits; (iv) evaluation of the new DSSAT Canegro model against datasets from Zimbabwe, Australia, USA and South Africa, and (v) documentation of code and concepts, as well as of the model evaluation experiments. Verification exercises conducted thus far show close agreement with the original Canegro results. An up-to-date DSSAT v4 Canegro will allow non-modelling experts to rn the model and will advance further development by enforcing a transparent modular structure. Evaluation against field experiments from different regions of the world will provide credibility and a benchmark for future improvements. | |
