PERSYST : Un outil d’évaluation des PERformances agronomiques, pour l’évaluation de la durabilité de SYSTèmes de culture

Laurence Guichard, Aïcha Attoumani-Ronceux, Rémy Ballot, Olivia Tavares, Chantal Loyce

Accompagner les agriculteurs à la réflexion sur des systèmes de culture en place nécessite de disposer d’outils d’accompagnement interactifs qui permettent au binôme “agriculteur / conseiller” d’explorer des possibles en matière de systèmes de culture et d’en estimer a priori les performances.

L’outil PERSYST, conçu par l’INRA, permet d’estimer le rendement des cultures en intégrant l’effet du système de culture dans lequel elles s’inscrivent (c’est à dire l’effet de la rotation et des itinéraires techniques mis en œuvre).

L’outil PERSYST a été paramétré en Bourgogne, en Eure-et-Loir et en Picardie en agriculture conventionnelle. En agriculture biologique, le paramétrage est disponible pour les régions Ile-de-France et Picardie.

L’outil est en cours de développement informatique et est disponible sous forme d’une application web en libre accès, accessible sur ce lien.
