Cacaoculture intensification has led to a reduction of the forest area and a continuous decline of woody trees number in cocoa plantations. In the context of climate change, Côte d’Ivoire, the world’s largest producer of cocoa beans, has opted for agroforestry practices to ensure sustainable cocoa production. However, the impact of this choice on cocoa production is not evaluated, let alone the characteristics of existing agroforestry systems. Our objective is to study the effect of different types of agroforestry systems on cocoa yield. Data on flora, DBH diameter, total height of the trees as well as on cocoa pod were collected in 60 plots of 400 m2 each. In addition, tree shading, and potential yield were calculated. The results showed that the diversity of agroforestry systems with cocoa trees includes 47 plant species distributed between 41 genera and 20 families. Factorial Multiple Analysis based on associated tree diversity, dimensions and shading has identified three types of agroforestry systems. Light shading systems had the highest cocoa yields (> 1000 kg/ha/year) while the yield with a dense shading varied from 500 to 1000 kg/ha/year. The absence of shading has a negative effect leading to less than 500 kg/ha/year. These results could help promote efficient Cocoa Agroforestry Systems.

Abstract: (french)
L’intensification de la cacaoculture a conduit à une réduction de la surface forestière et à une baisse continuelle du nombre de ligneux dans les plantations de cacaoyers. Dans le contexte actuel du changement climatique, la Côte d’Ivoire, premier producteur mondial de fèves de cacao, a opté pour l’adoption de pratiques agroforestières afin de garantir une production durable de cacao. Cependant, les conséquences de ce choix sur la production de cacao n’est pas évalué, encore moins les caractéristiques des systèmes agroforestiers existants. Notre objectif est d’étudier l’effet de différents types de systèmes agroforestiers sur le rendement en cacao. Les données sur la flore, le diamètre (DBH), la hauteur totale des arbres ainsi que sur les cabosses ont été collectées dans 60 parcelles de 400 m2 chacune. En plus, l’ombrage des arbres et le rendement potentiel ont été calculés. Les résultats ont montré que la diversité des systèmes agroforestiers à cacaoyers comprend 47 espèces végétales réparties entre 41 genres et 20 familles. L’analyse Factorielle Multiple basée sur la diversité, les dimensions et l’ombrage des espèces associées aux cacaoyers a permis d’identifier trois types de Systèmes Agroforestiers. Les systèmes à ombrage léger ont présenté les valeurs les plus élevées de rendements en cacao (> 1000 kg/ha/an) tandis que le rendement à l’ombrage dense a varié de 500 à 1000 kg/ha/an. L’absence d’ombrage a un effet négatif conduisant à moins de 500 kg/ha/an. Ces résultats pourraient permettre de promouvoir des Systèmes Agroforestiers à cacaoyers performants.
