Abstract: 

L’équilibre du maintien de la durabilité des systèmes de cultures d'ananas nécessite une adoption des pratiques alternatives durables. Ainsi, cette étude vise à évaluer l'effet de trois types de couverture du sol (paillis plastique biodégradable, couverture vivante avec Stylosanthes guianensis L., et sans couverture) sur les performances agronomiques et économiques de l'ananas Pain de sucre au Sud-Togo. A cet effet, un dispositif de bloc aléatoire complet à 4 répétitions a été mis en place pour la conduite de l’expérimentation. Les résultats obtenus montrent des différences significatives (p < 0,05) entre les traitements appliqués, et une forte corrélation entre le développement végétatif des plants et le rendement en fruit. La couverture du sol avec paillis en plastique biodégradable a permis d’augmenter de 25 à 30% significativement le rendement en fruits d’ananas avec la couronne soit 81,25±8,12 t. ha-1 contre 61,72±6,26 t. ha-1 pour le modèle classique sans couverture du sol et 56,25±4,06 t. ha-1 avec la couverture vivante et permanente du sol par S. guianensis. L’analyse économique des trois modèles a montré que le modèle du SPA sous paillis plastiques biodégradable présente une meilleure profitabilité en termes de richesse générée.
