Public ISBD Titre de série : Technical Bulletin Titre : An integrated model approach to the effect of water management on crop yield Type de document : texte imprimé Auteurs : Feddes, R. A. ; Wijk, A. L. M. (van) Mention d'édition : ILWMR IVCW Editeur : ILWMR IVCW Année de publication : 1977 ISBN/ISSN/EAN : CI-09440 Note générale : Quanttifying the effectof drainage on crop yield is of essential importance in agricultural management. In this article a model is described with which this effect can be computed for both arable land and grassland, the factor acting in spring, summer and autumn are deal with separately arable land. In spring sowing date is the main factor affecting the crop yield. Sowing date depends to the village conditions of the soil to player. In autumn crop yield is influenced by the working conditions during harvest yields are derived from an experimental relationship between yield depression and number of days of earlier harvesting grassland. The effect of shallow groundwater table depths in winter and spring an the yield of the first and second cut can be determined with the workability model in an identical manner to that given for arable land. An example representative for the Netherlands is given for grass on peat soil.
