Abstract:

SUMMARYIn Côte d'Ivoire, the world's largest cocoa producer, cacao (Theobroma cacaoL.) is usually grown from seed. The genetics consist of a mix of amelonado, trinitario and selected hybrids. This mix of varieties generates high phenotypic variabilities, including variability in tree productivity, within cacao populations in both smallholder and industrial plantations. Tree-to-tree variability in yield has been reported in cacao breeding trials under different environmental conditions. However, it has never been considered a limiting factor for agronomical performance of seedling-based cacao p

Currently, data about cacao been damage due to pathogen infection have not been updated. This study observed the incidence of major diseases in cacao plantations, included pod rot, canker, and vascular-streak dieback (VSD).

Abstract. In a landscape fragmented by agriculture, the extent to which forest-dwelling primates can use the matrix between fragments can be critical for their long-term survival. So far, the golden-headed lion tamarin (Leontopithecus chrysomelas), an endangered primate inhabiting the Atlantic Forest of south Bahia, is only known to use shaded cacao (Theobroma cacao) agroforests within the matrix. We report on the use of a rubber plantation by a group of golden-headed lion tamarins between August 2013 and January 2014.

Le département de Méagui dans le Sud-Ouest ivoirien figure comme l’un des derniers fronts de production de cacao en Côte d’Ivoire avec 50% de la production nationale de cacao (OIPR, 2015). Depuis 1970, la pression sur la forêt s’est accrue avec un taux important de migration et des pratiques culturales extensives. L’objectif vise à mettre en évidence les facteurs anthropiques sur les performances actuelles des systèmes de production cacaoyère. L’étude a privilégié la démarche qualitative à visée compréhensive des pratiques culturales. La revue documentaire, l’entretien et l’observation directe

Les producteurs de cacao ivoiriens font face à une nouvelle donne environnementale : en plus de la disparition du couvert forestier sous la progression des fronts pionniers cacaoyers, les systèmes conduits en monoculture montrent leurs limites et les évolutions climatiques récentes sont moins propices à cette culture. La conjonction de ces différents éléments conduit à une situation de blocage structurel. À la croisée de données environnementales et socio-politiques, cet article décrit et interroge les stratégies d’adaptation des producteurs de cacao dans ce contexte ≪ post-forestier ». L’anal

Abstract:

In smallholder cacao plantations, the protective crops used varied, so they have different effects on splash erosion. The management of land cover with a canopy of cacao and shade trees on cacao fields, aims to control of splash erosion. This study was conducted by directly measuring the magnitude of splash erosion under several levels of canopy cover. The magnitude of splash erosion was determined by measuring the depth of the eroded soil using the bottle cap method. The measurements were carried out every rain event (46 rain events with rainfall varied from 0.28 to 97.04 mm). The canopy cove

Abstract:

The cacao tree (Theobroma cacao L.) is native to the Amazon basin and widely cultivated in the tropics to produce seeds, the valuable raw material for the chocolate industry. Conservation of cacao genetic resources and their availability for breeding and production programs are vital for securing cacao supply. However, relatively little is still known about the phylogeographic structure of natural cacao populations. We studied the geographic distribution of cpDNA variation in different populations representing natural cacao stands, cacao farms in Ecuador, and breeding populations. We used six

Abstract:

Cocoa (Theobroma cacao L.) is an important crop in Peru. International regulations require products derived from cocoa to be free of heavy metals (HMs), such as cadmium. Arbuscular mycorrhizae (AM) contribute to reduced HM content in the plant, preventing its accumulation in the fruit and facilitating the rhizodeposition of HMs through glomalin-related soil proteins (GRSP). We studied the presence of mycorrhizal symbiosis in cocoa plants and cadmium in three plantations in San Martín, Peru. The maximum Cd content detected in soils was 1.09 (mg/kg), an amount below the tolerable limit for agric
