| Nos diversos compartimentos do agroecossistema de seringueira com cacaueiro, foram avaliados os estoques de materia organica e a quantificacao da biomassa vegetal. O estudo foi realizado em parcela de consorcio de seringueira com cacaueiro, com quinze anos de idade, instalado no Campo Experimental do Centro de Pesquisa Agroflorestal da Amazonia Oriental-CPATU, localizado no Km 40 da rodovia PA253, em Capitao Poco, PA. A quantificacao das fitomassas de seringueira e de cacaueiro foi realizada em junho de 1991, em cinco plantas de cada cultura do total de 140 plantas de seringueira e 960 plantas de cacaueiro por hectare. Em cada planta foram avaliados ramos, caule, folhas e raizes (pivotante, grossas e finas), estas ate um metro de profundidade no solo. O... |

| ABSTRACT: Ecuador is responsible for up to 70 % of the world’s production of fine flavor cocoa. Although fungal diseases have reduced cocoa production, eco–friendly alternatives have been implemented to control the spread of phytopathogens. This study aimed to explore the potential of endophytic strains isolated from fine flavor Nacional cocoa trees to synthetize compounds with antimicrobial and surface active properties. It was determined that under in vitro conditions, seven strains (DS03, DS07, DS18, DS23, DS31, DS34 and DS50) exhibited antifungal activity that inhibited the mycelial growth of Moniliophthora roreri and Moniliophthora perniciosa. The strains were identified based on their morphological (pattern forming Bacilli) and genetic... |

| Abstract: Bioaccumulation of heavy metals such as cadmium has been a major concern in scientific communities and international food organizations, given the great toxicological risk to the consumer, and in many places there is no detailed record of its actual content. In this way, the need arises to carry out a study and registration of the concentration of this metal in products such as table chocolate, of great consumption at regional and national level. Likewise, we seek to have effective quantification tools and a reliable and affordable method to achieve the aim of this research. In this research, Cadmium content in powdered and granulated table chocolate was determined, elaborated and commercialized in the municipality of Chiquinquira,... |

| In the Peruvian jungle, there are two main cocoa marketing channels: the intermediaries and the cooperative. For example, the Acopagro Cooperative, a Peruvian organization, has contributed to the shift from illegal crops like coca to an alternative crop like cocoa which gives small scale farmers a sustainable welfare. Despite the fact that the Acopagro cooperative benefits their members by paying a fair price, supplying technical assistance and credit, many farmers still prefer commercializing their cocoa via the intermediaries. A further analysis of cocoa prices was carried out through personal interviews and a survey made between December 2009 and January 2010, of 243 farmers in Juanjui, San Martin, Peru's main cocoa production area. The outcomes... |

Cocoa is one of the principal agricultural and cultural resources of the humid Mexican tropics. At present, the cocoa system is facing an unprecedented production crisis in relation to several factors, including the presence of frosty pod rot (Moniliophthora roreri), plantation neglect and low farm profitability. The aim of this study was to formulate a medium-term plan for cocoa production in Mexico by constructing a Technology Roadmap (TRM). Using an econometric model, production statistics were analyzed for national and international data. Producers participated in 185 surveys,... |

| Este artigo trata da aplicabilidade de modelos da família ARCH como ferramenta de análise quanto ao comportamento do retorno do cacau, do boi gordo, do café, tradicionais commodities agrícolas brasileira, servindo de auxílio para decisão dos agentes na compra e venda destes produtos. De forma geral, para as três commodities estudadas, as volatilidades do retorno indicam fortes sinais de persistência, os choques levam um longo tempo para dissipar-se, e choques positivos e negativos têm impacto distinto sobre a volatilidade. Os mercados são assimétricos para o retorno destas commodities. Os mercados futuros do boi gordo e do cacau também sofrem influência do efeito alavancagem, ou seja, se torna mais volátil perante informações negativas do que informações... |

| Previous attempts at identifying and estimating a time-varying risk premium in the cocoa futures market yielded conflicting results. Using a longer series that includes the most recent cash and futures data, the existence of a time-varying risk premium in the cocoa futures market is re-investigated using LM ARCH tests and a Quadratic ARCH in Mean Error Correction Model. In contrast to available research the time series properties of the data are carefully accounted for by employing the most recent econometric techniques in testing for the presence of a risk premium. No evidence is found in support of a positive time-varying [or constant] risk premium in the cocoa futures market at conventional significance levels. The result suggests that cocoa producing... |

| This study sets out to empirically estimate the optimum annual replacement rate and age of cocoa trees in order to maximize the net present value of four common cocoa production systems. The study examines the costs and returns of four common cocoa production systems in Ghana associated with changes in cocoa prices, fertilizer prices, inflation rates, and labor prices. While this study focuses on cocoa, the methodology is applicable to any perennial crop. This study uses empirical yield curves and cost of production data from Ghana to determine when and what percentage of a cocoa orchard should be replaced annually to maximize net present value of revenues over time. Successive versions of the model are solved to determine how input and output price... |

| Este trabajo estudió la sostenibilidad de los hogares productores de cacao orgánico. Se utilizó el enfoque de Medios de Vida Sostenibles (MVS), el cual establece una tipología de los activos que los pobres utilizan para mantener su bienestar bajo condiciones ambientales, sociales y económicas cambiantes. El objetivo fue identificar los medios de vida de las familias productoras de cacao orgánico y conocer las principales estrategias utilizadas para su sostenibilidad. La investigación se realizó en dos comunidades de Cunduacán, Tabasco. Se combinaron métodos cualitativos y cuantitativos para: conocer los activos de los productores de cacao orgánico certificado de la zona de estudio (28 productores, 14 hombres y 14 mujeres); distinguir los... |
