Introduction
Overall objectives remain to link a mechanistic model of cell-to-plant
photosynthesis, such as WIMOVAC, constructed by the ESSEX partners (Humphries and Long,
1995), with a phenological crop model of sorghum yield, such as CERES, adapted for sorghum
by the INRA partners (Jegu, 1994; Medeiros, 1997). The model should be designed for use by
scientists and managers, and should be able to be run on a standard PC with Microsoft
Windows.
It had been agreed that ESSEX would construct the above ground model, and INRA would
work on modelling the below ground processes.
The workplan for this period was
1) to incorporate the crop phenological stages of sorghum determined by elapsed thermal
times, above a base temperature, into WIMOVAC, based on the growth stages of the
CERES-Sorghum model.
- to adjust the model, based on the relationships within the CERES-Sorghum model, to
simulate the observed dry matter production of sorghum crops grown in five locations
within Southern Europe.
3) to test the model against experimental data.
No changes to the workplan beyond those reported previously.
