Coconut fiber is the substrate of choice for the production of plants in vegetable nursery above ground Gabon. However, procurement and production costs of the material remain high. This study conducted in the experimental area of the company Horta Gabon, located in the town of Akanda north of Libreville in Gabon, with the aims to test the possibility of substituting coconut fiber imported by coffee husks produced locally. Thus, through monitoring of the germination and vegetative behavior of Tomato seedlings (Lycopersicon esculentum) subject to various disinfection treatments, which have focused on the nature of disinfectant and the volumes applied, have showed that plants of tomato products on coffee husks disinfected 1.5 L of Metam Sodium (MS) and washed have better returns in terms of germination and development of tomato seedlings. These results indicate that the coffee husk could be an alternative substrate of coconut fiber without causing major imbalances.

Abstract
Coconut fiber is the substrate of choice for the production of plants in vegetable nursery above ground Gabon. However, procurement and production costs of the material remain high. This study conducted in the experimental area of the company Horta Gabon, located in the town of Akanda north of Libreville in Gabon, with the aims to test the possibility of substituting coconut fiber imported by coffee husks produced locally. Thus, through monitoring of the germination and vegetative behavior of Tomato seedlings (Lycopersicon esculentum) subject to various disinfection treatments, which have focused on the nature of disinfectant and the volumes applied, have showed that plants of tomato products on coffee husks disinfected 1.5 L of Metam Sodium (MS) and washed have better returns in terms of germination and development of tomato seedlings.

Abstract: (french)
La Fibre de coco constitue le substrat par excellence pour la production des plants en pépinière maraîchère hors sol au Gabon. Cependant, l’approvisionnement et les couts de production de ce matériau restent encore élevés. Cette étude conduite dans le domaine expérimental de la société Horta Gabon, située dans la commune d’Akanda au nord de Libreville, au Gabon, a pour but de tester la possibilité de substituer la fibre de coco importée par la parche de café produite localement. Ainsi, à travers un suivi du comportement germinatif et végétatif des plants de Tomate (Lycopersicon esculentum) soumis à divers traitements de désinfection, qui ont portés sur la nature du désinfectant et les volumes appliqués, nos résultats ont montré que les plants de Tomate produits sur parche de café désinfecté à 1,5 L de Metam Sodium (MS) et lavée présentent des meilleurs rendements en termes de germination et de développement des plants. Ces résultats indiquent que la parche de café pourrait constituer partiellement un substrat alternatif à la fibre de coco sans entrainer des déséquilibres importants.
