From ORYZA2000 to ORYZA (v3): An improved simulation model for rice in drought and nitrogen-deficient environments

View Article: PubMed Central - PubMed

ABSTRACT

Improvements in ORYZA (v3) were identified and compared to ORYZA2000.

Soil carbon, nitrogen, and temperature dynamic modules were developed.

Algorithms for the effects of environmental stresses on rice growth were improved.

Case studies confirmed successful improvement of the model.

Case studies confirmed successful improvement of the model.

The model structure of ORYZA (v3), which has an improved capability to simulate rice growth and yield for lowland, as well as upland, rainfed, and aerobic rice ecosystems. Modified routines are shown in double-framed boxes, while new modules and routines are shown in black and gray boxes, respectively. Lines connecting the boxes indicate the two-way flow of information and/or mass exchange, while single-headed arrows indicate unidirectional mass and/or information flow.

Mentions: The older versions of ORYZA, ORYZA2000 v1 to v2.13, provide reliable simulations of rice growth in lowland ecosystems and changes (Fig. 1) were implemented on the model to develop an upgraded version. New modules (black boxes) and additional routines (gray boxes) were developed and integrated, while old routines (double-frame boxes) were modified to achieve additional and/or alternative functions in ORYZA (v3).
