L’objectif de cette étude était d’évaluer l’effet à court terme du non labour avec paillage sur le rendement du haricot (Phaseolus vulgaris L.). Le haricot de type nain a été semé sur des parcelles labourées et non paillées (T0), des parcelles en non labour avec un paillage de résidus de bananier (T1) ou de feuilles de Tripsacum laxum (T2). Le paillage a été appliqué à la dose de 12,5 tonnes de matière sèche ha-1 an-1. Le rendement du haricot a été évalué pendant deux saisons culturales consécutives. A la première saison culturale (‘saison 2011A’), T0 a donné un re4ndement significativement (P<0,01) supérieur à ceux de deux autres traitements. A la deuxième saison (‘saison 2011B’), par contre, aucun traitement n’a amélioré de manière significative le rendement du haricot. Toutefois, le rendement le plus élevé a été obtenu sous T2 (865 kg ha-1) comparé à T0 (660 kg ha-1) et T1 (597 kg ha-1). Pour le site d’étude, la conversion des parcelles préalablement soumises au travail manuel du sol en non labour avec paillage n’aurait donc pas d’impact négatif sur le rendement du haricot dans le long terme. Toutefois, le choix de résidus organiques pour le paillage serait nécessaire pour accroitre l’efficience de leur utilisation.
