ECONOMIC CONSEQUENCES OF UNCERTAIN CLIMATE CONDITIONS FOR CROP PLANNING IN GREENHOUSE PRODUCTION |
| Author: | A. Werthwein |
| Abstract:
Horticultural production is exposed to many uncertainties with regard to the prediction of environmental conditions, due to i. a. fluctuating climate conditions. These may have important consequences for the cultivation and the economic outcome. 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 and of the variables influencing the gross margins which have to be considered but also their possible variations. As an example three different cropping systems of radish are compared with regard to the variation of their cultivation periods, yields, energy consumption and 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 variation range and of the average is shown for the cultivation period and the gross margin of a selected cropping system of radish. | |
