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...

Ano: 2008 URL: http://purl.umn.edu/109785 The Role of Credit Access in Improving Cocoa Production in West African Countries AgEcon Nyemeck, J.B.; Gockowski, James; Nkamleu, Guy Blaise. This study uses survey data to examine the role of access to credit on cocoa production, in West African cocoa production countries under conditions of agricultural policy liberalization. The study specifies and estimates econometric models to simulate the counterfactual of what cocoa production would be in the absence of credit facilities. The survey results show that about 54% of cocoa farmers have access to credit in Nigeria, and respectively 37% in Cameroon, while in Ghana and Côte d’Ivoire only a few cocoa farmers have access to credit. We find that the cocoa farmer’s capacity such as, the cocoa farm size, and the mutuality status of the farmer are more important as a determinants of cocoa farmers access to credit as well as another set of variables...

ABSTRACTThe main objective of the present research was to calculate the water footprint of the Colombian cocoa (Theobroma cacao L.) production. The evaluation of crop water requirement and irrigation requirement were based on climate, soil and crop conditions in the country. The water requirement estimation was based on data from six municipalities selected for their representativeness of the highest yield, productivity and commercial dynamics of the country. The results show that the Water footprint reached 17,100 m3 t-1. At the province level, the highest record for this parameter was observed in Tolima, with 23,239 m3t-1, while Huila registered the lowest level, with 13,475 m3t-1. Water use per crop unit can be influenced not only by agro-meteorological...

ABSTRACT The knowledge on the spatial variability of soil properties and crops is important for decision-making on agricultural management. The objective of this study was to evaluate the spatial variability of soil fertility and its relation with cocoa yield. The study was conducted over 14 months in an area cultivated with cocoa. A sampling grid was created to study soil chemical properties and cocoa yield (stratified in season, off-season and annual). The data were analyzed using descriptive and exploratory statistics, and geostatistics. The chemical attributes were classified using fuzzy logic to generate a soil fertility map, which was correlated with maps of crop yield. The soil of the area, except for the western region, showed possibilities ranging...

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...

(Palmira) Chaparro-Acuña,Sandra Patricia; Vargas-Moreno,Paola Andrea; Silva-Gómez,Leonardo Andrés; Cárdenas,Oswaldo Eliécer. 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 present work, cacauhy's (Theobroma speciosum) floral biology was studied. Flower buds split their sepals at 14h reaching its maximum at 22h, but all flowers were fully opened at 6:00 h of the following morning. Stigmatic branches showed exudates, reaching maximum between 6:00 h and 10:00 h at the same day. Ligules and petal hoods were the floral parts with highest intensity of odour. Flowers were receptive along all the morning and noon of the anthesis day. Approximately 65% of the flowers were naturally pollinated, but only 0.85% of them set a fruit. Abscission occurred on its higher frequency at 6:00 h of the second day after anthesis. Controlled pollinations showed that cacauhy was self-incompatible species.

Protein hydrolysis using an exogenous protease on cocoa nibs was performed to verify the formation of precursors and the effect on cocoa flavour. An experimental design was used to check the influence of temperature (30 to 70 ºC) and enzyme : substrate ratio [E/S] (97.5 to 1267.5 U g-1 of protein). The % Degree of Hydrolysis (% DH) was affected mainly by [E/S] leading to a 4-fold increase (from 5 to 20 %) after 6 hours of treatment. During cocoa nibs roasting, there was a greater consumption of hydrolysis compounds in the sample treated with protease as compared to the control, indicating their participation in the Maillard reaction. An increased perception of chocolate flavour and bitter taste was observed in a product formulated with protease treated...

A field emission electron microscope (SEM) was used to study the conidia surface of Trichoderma stromaticum, a biocontrol of witches broom disease of cocoa. Surface features of conidia were difficult distinguish by light microscope. Conidia appeared to be verrugose and minutely roughened, but the nature of the roughening was not easy to discern. It was common to observe sheath-like structures that completely covered groups of conidia, and also details of wide cells that form the pustules.

Horacio. O. Díaz-José, J. Aguilar-Ávila, R. Rendón-Medel, and V.H. Santoyo-Cortés. 2013. Current state of and perspectives on cocoa production in Mexico. Cien. Inv. Agr.40(2): 279-289. 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,...
