A BIO-ECONOMIC MODEL FOR HEATED GLASSHOUSE TOMATOES. |
| Authors: | T. Biemond, W.G. Trap |
| Abstract:
Harvest-planning for heated glasshouse tomatoes is necessary in areas of labour-shortage. A bio-economic model was developed to estimate the expected need for labour. This model incorporates factors as plant status, glasshouse characteristics, outside and inside climate (temperature, CO2-concentration and radiation-intensity). Because the production is estimated too, this model can be a base for optimization of CO2-concentration and temperature when the prices of energy (gas) and tomatoes are known. Also the gross-margin is estimated. This article gives an overview of the structure of this model. Some preliminary results of the model are shown. | |
