ORYZA Training Program

Crop modeling and systems analysis have become important tools in modern agricultural research. ORYZA model, the latest in the list of progeny, progressively developed and updated as the science of rice production grows. As a rice model, it continues to simulate growth and development of rice under wider range of environment after thorough
• testing of hypotheses through field experiments;
• extrapolating observed data through simulations; and
• converting simulation results to decisions through practical information.

It remained widely used in simulations related to various rice research addressing

• optimization of water and nitrogen management;
• identification of constraining factors on yield within site-specific conditions;
• assessment of the climate change effects on production;
• exploration of management options and sustainability of cropping systems;
• evaluation of varietal performance and effects of traits on target environments; and
• germplasm adaptation to climate change.

The ORYZA modeling team has been conducting training programs to continuously provide support in ORYZA modeling studies.

ORYZA Training Program for Basic Applications

The overall goal of this training program is to familiarize participants with the basic functionalities and structure of the ORYZA model, the minimum data requirement, experimental data collection for ORYZA model evaluation, the calibration of parameters, and the use ORYZA on your own dataset.

Program highlights

• Demonstrate how processes of crop growth and development, water use, uptake of water, and nutrients and
  carbon dynamics can be 
• Make extensive use of “hands-on” sessions that apply the ORYZA model to field experiments.
• Describe procedures for collecting and managing crop, experimental, weather, and soil data for model evaluation.
• Give participants the opportunity to work with their own data and determine the accuracy of the model for
  application to specific problems.
• Analyze management alternatives for single seasons or over long-term crop rotations.

Advanced Applications of ORYZA in Rice Research

This training aims to improve and extend the skills of ORYZA users for more advanced application studies, which may require thousands or even millions of simulations.

Program highlights

• Managing large-scale simulations with ORYZA: data handling, input file organization, simulation management, and
   output analysis for 
regional grid-cell simulations;
• Using ORYZA for climate change study: impact assessment and optimizing adaptation strategies for rice
   production under climate change;
• Using ORYZA for rice breeding: evaluating the performance of breeding lines in a large number of environments,
   identifying the hot spots for 
dissemination of varieties, and differentiating the contribution of specific breeding
   traits; and
• Using ORYZA for crop management optimization: optimizing cropping calendar, planting density, and water and
   nitrogen application for a 
specific site.

The ORYZA model Training courses are usually be conducted at the research campus of IRRI, Los Baños, Philippines. International participants are encouraged to arrive at least one day prior to the start of the program to adjust and recover from travel fatigue.

Los Baños is small city located 60 km south of Manila and may take 1.5 hours travel time, depending on traffic conditions from Manila International Airport. We will forward travel instructions after your registration.


The IRRI Swaminathan Hall dormitory and IRRI Guesthouse are available. There are wi-fi access points in all buildings at the IRRI campus to provide 'almost seamless' wi-fi connectivity. Wi-fi networking on campus is meant for business use, the terms and conditions that apply to our 'cabled' research network also apply to our wi-fi services.
