Abstract

In their simplest form, crop models consist of regressions relating factors such as yield to environmental variables. Explanatory models also exist, with much physiological detail and responsiveness to meteorological and soil factors. Summary models can be derived from such large models, including the influence of pests. Of these major types of models, regression models are increasingly becoming widely used to optimize and integrate the many facets of cereal management in Western Europe. This fact suggests that crop manipulation is evolving toward optimal production management.

Résumé

L'expression la plus simple d'un modèle de culture est une régression reliant des variables comme le rendement aux facteurs du milieu. Les modèles dits explicatifs incorporent quantité de détails physiologiques et de réponses aux facteurs du sol et du milieu. Des modèles particuliers peuvent être dérivés de ces modèles d'ensemble, y compris pour modéliser l'influence des organismes nuisibles. Parmi ces divers types de modèles, les modèles de régression sont de plus en plus utilisés afin d'optimiser et d'intégrer les diverses facettes de la régie des céréales en Europe de l'ouest. Ceci indique que la manipulation des cultures est en train d'évoluer vers une régie optimale de production.
