Evaluation Du Rendement De Deux Variétés De Cacaoyers Dans La Région Du Centre Du Cameroun

Abstract

Résumé Le Gouvernement camerounais, à travers le FODECC (Fond de Développement Cacao Café) a lancé un programme de développement de la filière cacao afin d’en accroître la production dans le but d’atteindre 600 000 tonnes à l’horizon 2020. Ce programme consiste à distribuer gratuitement des plants hybrides considérés de très productifs aux paysans. Certains hybrides distribués tels que SNK 413 sont très peu étudiés. Leur productivité dans une agroforêt reste mal connue d’où l’objet de cette étude. Afin d’évaluer la production du cacao dans les agroforêts, une étude a été conduite pendant trois années consécutives dans le bassin de production du Département de la Lékié, Région du Centre du Cameroun. L’objectif principal est de comparer la production d’un hybride (SNK 413) à celle d’une variété locale (Bat 1). La détermination de la quantité de cacao marchand de chaque variété a été effectuée dans des parcelles placées sous ombrage homogène (absence d’ouverture de la canopée). Elle a consisté dans un premier temps à collecter des informations sur le terrain auprès des cacaoculteurs à l’aide des trames d’enquêtes semi-structurées. L’exploitant déclare les quantités récoltées suivant l’unité locale de récolte (sac en général) qui est convertie en kilogramme à l’aide d’une procédure d’étalonnage de poids. Dans un second temps, elle a servi à déterminer au champ le nombre de pieds de cacaoyers par hectare, le nombre de cabosses et de fèves. Dans les parcelles, il a été constaté que le rendement potentiel en cacao marchand est lié positivement au nombre moyen de cabosses par cacaoyer (r = 0,721). Par contre, le rendement potentiel en cacao marchand n’est pas corrélé à la densité des cacaoyers (r = - 0,108). La quantité de cacao marchand produit par hectare est plus élevée pour SNK 413 (2519,37 kg) que pour Bat 1 (784 kg). Par conséquent, SNK 413 est une variété qui produit trois fois plus que Bat 1. Abstract Cameroonian Government, through FODECC (Cocoa and Coffee Development Fund) have launched cocoa development program to increase production of cocoa in order to rich 600 000 ton production at 2020 horizon. This consists to offer freely hybrid plants which are supposed very productive to farmers. Certain hybrids like SNK 413 are not well studied. Their productivity in an agroforest is not well known. An therefore, justify this study. This study which concerns the cocoa production area of the Centre Region of Cameroon started in June 2012 till November 2015 in many localities of Lekie Division. The main objective of this study was to compare the hybrid production (SNK 413) with the local specie (Bat 1). The determination of the quantity of cocoa product of theses two species has been done in each parcel of land which is only situated under homogeneous shades (no canopy open). It has consisted firstly to collect information from the cocoa farmers on the field. Cocoa farmers declare their production quantity in bags which are converted in kilogram. Secondly to collect from the farms the number of cocoa trees per hectare, the number of cocoa pods and cocoa beans. For these two parcels of land, the productivity of cocoa tree is positively linked to the average number of cocoa pods per cocoa tree (r = 0,721). On the contrary, the potential productivity of cocoa product is not linked to density of cocoa trees (r = - 0,108). The quantity of cocoa product per hectare is higher for SNK 413 (2519, 37 kg) than Bat 1 (784 kg). SNK 413 produces three times more than Bat 1.
