Intégration des contraintes du marché dans la conduite des cultures: effets de la différentiation des produits sur la conduite de la culture de pomme de terre de conservation dans les exploitations agricoles de Picardie

Abstract : The ways of integration on the farms the new technical specification generated by the segmentation of the market were studied for the potato crop, taking into consideration the differentiation of final products on the industrials and fresh channels. This research investigated the technical decisions taken by the farmers of a sample of sixteen farms of Picardie's region. Comparative analyze of the various qualities requirements regarding many products allowed discerning, according to the degree of elaboration of the final product in the farm, three products type: raw material, semi finished and finished wares. The technical operation prescriptions were classified on three levels, according to the manner to check the application by the farmers: obligatory, recommended and indifferent. The integration of the external requirements in the technical management of the potato break of a farm is submitted to a principle of the respect of an obligation and to a principle of simplification. The first one indicates that if a obligatory operation on a type the product is required than the farmer respect this exigency at least on this product type. The simplification principle stipulated that until an operation is indifferent on the whole crop break, it is conceived to be homogenized the most possible one. The ratchet effect, consequence of these principles, consists to extrapolate the most possible on the break crop the obligatory or recommended technical exigency for a product type. The number of field plots by technical operation that resulted, is often lower to the number of products presented in crop break, but higher or equal to the number of obligation concerning to the operatn. For the whole cultural cycle, the number of plots of cultures is lower than the number of the products on the break potato crop.
