  abstract = {{T}he choice of tree species planted with cacao trees is essential for ensuring the efficiency and sustainability of cacao farming systems. {T}his raises the question of the long-term impact of associated tree legumes ({ATL}s) on cacao bean yields and biomass accumulation. {T}his study was carried out in accordance with four-block randomised experimental design in {D}ivo ({I}vory {C}oast, {W}est {A}frica). {T}he study involved cacao-{A}lbizia lebbeck ({C}acao-{A}lb) and cacao-{A}cacia mangium ({C}acao-{A}ca) intercrops and unshaded cacao plots ({C}ontrol). {A}fter 20 years of intercropping, we assessed cacao dendrometry (height, circumference, biomass, and biomass {C}-stock) and production (number of pods per tree and bean yield at the plot level) as well as soil fertility (soil organic matter ({SOM}) concentration) at various distances from {ATL}s ({D}1:0-1.75 m; {D}2:3.25-5 m; {D}3:7-9 m). {T}he distance from the {ATL}s had no significant effect on the measured cacao dendrometric parameters, except for cacao height. {I}n contrast, the {C}acao-{A}ca association had a negative impact on the {SOM} concentration (-22%), cacao tree height (-6.15%), and productivity parameters (biomass: -12.4%; bean yield: -43%). {H}owever, {C}acao-{A}lb and the {C}ontrol had no significant differences in terms of {SOM}, tree biomass, or bean production. {I}ntercropping cacao with the tested tree legumes did not enhance cacao productivity and, in some cases, hindered it, depending on the {ATL} species. {T}his study highlighted the importance of identifying appropriate shade tree legume species that could be promoted in cacao-based agroforestry systems.},
