Horticultural production is exposed to many uncertainties with regard to the prediction of environmental conditions, due to i.a. fluctuating climate conditions.
In the planning situation before beginning the crop different crops or cropping systems are compared.
In such a comparison it is not only the expected amount of the gross margins which has to be considered but also their possible variations.
As an example three different crops of rose 'Sonia' are compared with regard to the variation of their gross margins.
In the control situation during the cultivation the expected values of the plan data are successively replaced by real data registered until the respective date of control.
Thus the variation of the expected values will be reduced in the course of production.
As an example the development of the expected energy consumption of one crop of rose 'Sonia' is shown.
