ORYZA2000 tutorial has been developed that guide users of ORYZA2000 through the FSEWin Shell, the parameterisation and running of the model (input and output data control), and the interpretation of model results. All software (FSEWin, ORYZA2000), data sets and exercises can be freely downloaded. Through this, readers are encouraged to experiment with the model and apply it in their own research. All ORYZA2000 materials are a joint product of the International Rice Research Institute and the C.T. De Wit Graduate School of Production Ecology and Resource Conservation of Wageningen University and Research Centre.
After downloading and installing FSE/FSTWin and ORYZA2000 (click here for instructions) you shall be ready to perform these exercises:

This introduces you to the basic functionalities of the FSEWin Shell and the structure and files of the ORYZA2000 model.
The navigation exercises focus on the use of the experimental data file, and especially on the use of parameters that describe the crop management in the field (such as mode of establishment and transplanting date). Herewith, insight is built on the effect of crop management on the growth and production of rice.
A special set of exercises explains the use and manipulation of weather data files, and another set explains how to easily make a large number of reruns with the model.
The crop data file is always needed in ORYZA2000 modeling and simulation. It contains parameters that describe the rice variety under consideration. Most of the crop parameters for rice are generic and can be used for all varieties. However, some parameters and functions are best calibrated especially for the variety and environment under consideration.
A thorough discussion on calibration and validation of ORYZA2000 can be found HERE.
