MODELLING FOR CROP GROWTH CONTROL
In climate control one is primarily concerned with rapid responses of the crop. Crop growth models used for climate control therefore should be particularly strong in an accurate prediction of the instantaneous rate of photosynthesis and transpiration of the crop in relation to the environmental factors.
Models that are used for prediction of crop growth over weeks or months can deal with photosynthesis in a more simple way. There are, however, much higher demands with respect to developmental processes such as formation of leaves, flowers, fruits, maturing, etc. Models used for this purpose are more crop specific than the first mentioned category and due to a lack of basic understanding of the underlying processes, have to be more descriptive.
