Cocoa mirids, Sahlbergella singularis and Distantiella theobroma, are the most economically important insect pests of cocoa in West and Central Africa, where they can cause up to 40% losses in cocoa yields. Sahlbergella singularis is the most common species in Cameroon and was therefore targeted ...

García Ocampo, A.León Sarmiento, Luis Alfredo[Respuesta de cinco híbridos de cacao (Theobroma cacao L.) a toxicidad causada por aluminio en solución nutritiva y en un oxisol de los Llanos Orientales]Respuesta de cinco híbridos de cacao (Theobroma cacao L.) a toxicidad causada por aluminio en solución nutritiva y en un oxisol de los Llanos Orientales

Cacao is an important smallholder crop in West Africa, often grown under a forest canopy. Yields from cacao farms are low so farmers consider removing shade trees, however, the impacts on pest and disease dynamics, soil fertility and thus yield in the longer term are not understood. We estimated ...


Norgrove LHauser S[Carbon stocks in shaded Theobroma cacao farms and adjacent secondary forests of similar age in Cameroon]Carbon stocks in shaded Theobroma cacao farms and adjacent secondary forests of similar age in Cameroon

Shade trees are an integral part of most cocoa growing systems across the world. This study assesses farmers’ local knowledge of shade trees at two locations in Ghana with different climatic conditions and vulnerability to climate change. Akumadan is located in the northern dry part of the cocoa ...

En Ikom, Nigeria del Sudeste, se realizó en el año de 1981/82 un análisis en campo de sistemas de cultivo orientados al cacao en suelos basálticos. El objetivo fue elaborar las principales características del sistema de producción y sus limitaciones. El sistema se realiza en dos grupos de product...
