The aim of the study was to assess the impact of cocoa-based agroforestry practices on natural soil productivity. The methodology consisted in identifying three cocoa-based agroforestry systems (simple, mixed or complex) guided by the opening of the canopy of various floristic species associated with cocoa trees, in which three 100 m2 plots were randomly set up to inventory the arboricultural species encountered, determine species density and plantation yields. The results identified 17 tree families divided into 27 plant species, of which 55.55% were found in the simple agroforestry system (SAGS), with a density of 55 trees/hectare, 70.37% in the mixed agroforestry system (SAGM), with a density of 155.33 trees/hectare, and 81.40% in the complex agroforestry system (SAGC), with a density of 224.33 trees/hectare. In terms of particle size, the SAGS and SAGC had a silty texture, whereas the SAGM had a silty-clay texture. Major element, trace element and clay-humus complex contents were satisfactory in all agroforestry systems, but in decreasing order in SAGM, SAGC and SAGS. Cocoa productivity was higher in SAGS (403.42kg/ha), than in SAGM (293.61kg/ha) and SAGC (204.68kg/ha). In conclusion, it should be noted that each forest agrosystem has very distinct characteristics and contributes to soil fertility at depths of 0-20cm. Moreover, SAGS is the agroforestry system with the best production and can be recommended during the establishment of cocoa plantations in Côte d’Ivoire.

Abstract: (french)
L’objectif de l’étude était d’évaluer l’impact des pratiques agroforestières à base cacaoyers sur la productivité naturelle des sols. La méthodologie a consisté à identifier trois systèmes agroforestiers à base cacaoyers (simple, mixte ou complexe) guidés par l’ouverture de la canopée des diverses espèces floristiques associées aux cacaoyers dans lesquels, ont été posées au hasard trois placettes de 100 m2 pour inventorier des espèces arboricoles rencontrées, déterminer la densité des espèces et les rendements des plantations. Les résultats ont permis de recenser au niveau floristique, 17 familles arboricoles reparties en 27 espèces végétales dont 55,55 % en système agroforestier simple (SAGS) avec une densité de 55 arbres/hectare, 70,37 % en système agroforestier mixte (SAGM) avec une densité de 155,33 arbres/hectare et 81,40% en système agroforestier complexe (SAGC) avec une densité de 224,33 arbres/hectares. Au niveau granulométrique, les SAGS et SAGC ont présenté une texture limoneuse alors qu’elle a été limono-argileuse en SAGM. Les teneurs en éléments majeurs, oligo-éléments et complexe argilo-humique engendrées, ont été satisfaisantes quel que soit le système agroforestier, mais dans un ordre décroissant en SAGM, SAGC et SAGS. La productivité des cacaoyers a été meilleure en SAGS (403,42 kg/ha), qu’en SAGM (293,61kg/ha) et en SAGC (204,68kg/ha). En conclusion, notons que chaque agrosystème forestier a des caractéristiques bien distinctes et contribue à la fertilité du sol à la profondeur 0-20cm. Par ailleurs, SAGS est le système agroforestier qui a la meilleure production et peut être recommandé pendant la mise en place des plantations à base de cacaoyers en Côte d’Ivoire.
