The model simulates oil palm growth and production under potential or water limited production circumstances. The photosynthesis routines of SUCROS*87 are the backbones of the potential productivity model. Dry Sahel (DRSAHE) water balance is used to model water limitation. Dry matter partitioning is based on Corley's overflow hypothesis of yield.
Purpose of the model:
Model parentage: Based on SUCROS*87.
Source of the AbstractCAMASE Register of Agro-ecosystems Models
II. Technical Information
Operating System(s): Mainframe, mini, or PC. Contract necessary: Costs: Comments:
Programming Language(s): Microsoft FORTRAN and FSE*.
III. Mathematical Information
Rate variables: Daily canopy photosynthesis, maintenance and growth respiration are based on SUCROS*. A long term assimilate pool is kept to avoid negative growth rates.
Input check in model: Yes.
All state and rate variables plus intermediate values.
Basic spatial unit: Ha.
Time interval of simulation: Up to 25 years.
V. Further information in the World-Wide-Web
VI. Additional remarks
Parentage: Based on SUCROS*87.
