    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

    A growth model for heated glasshouse tomatoes is described in detail. A mechanistic approach is used so that both development and real growth are distinguished for both crop and fruit. Some results of the growth model as part of a bio-economic model are given. Of the different phsyiological processes, the rate of photosynthesis showed the largest influence on productivity. Other regarded aspects are: rate of flowering and maturing, tomato type, intercropping and planting date.
    A glasshouse climate model as part of a bio-economic model.

    Bio-economic models can be used as base for decision support systems. In protected cultivations, the glasshouse climate is of major importance on the financial result, both by costs and by yield. In this paper, a mechanistic climate model is described in detail. This glasshouse climate model is repartioned into four submodels: radiation- and lightintensity, heat- and daily ventilation need, mean day- and 24 hours temperature and a gas consumption submodel. Variation in CO2-concentration and low temperatures, especially at night had a large influence on the productivity.
