This research aimed to establish critical limits for the commercial classification and biochemical attributes of cacao beans that would reflect an optimal quality range by classifying the observations of the samples by the fermentation index (FI). Boundary line regressions represented the response of brown cacao beans, purple cacao beans, partially...
The cocoa and derivatives industries use pH as a biochemical parameter to verify the samples quality and infer their potential for flavour and aroma, without resorting to complex analytical methods. For this reason, we sought to determine a pH range in dry cacao beans (DCB) whose free amino acids (FAAs) response was associated with satisfactory val...
Free amino acids in cacao beans are important precursors to the aroma and flavor of chocolate. In this research, we used inferential and explanatory statistical techniques to verify the effect of different edaphic crop conditions on the free amino acid profile of PH-16 dry cacao beans. The decreasing order of free amino acids in PH-16 dry cacao bea...
Cacao crop is under pressure due to the high global consumption of this commodity, a fact that exposes the great need of technical precision for nutritional diagnosis and fertilizer recommendation in the plantations. The objective of this work is to review and to use the available information in the literature and the opinion of the cacao crop expe...
Cacao (Theobroma cacao L.) was grown as an understory tree in agroforestry systems where it received inadequate to adequate levels of photosynthetic photon flux density (PPFD). As atmospheric carbon dioxide steadily increased, it was unclear what impact this would have on cacao growth and development at low PPFD. This research evaluated the effects...
The mineral nutrient ratios are parameters for evaluating the crop nutritional balance through foliar analysis. This study aimed to verify the correlations between the main mineral nutrient ratios in leaves and the cacao productivity of 48 cropping areas. The chemical analyses were carried out to determine foliar N, P, K, Ca, Mg, S, Fe, Zn, Cu and...
The understanding of the mineral nutritional status of the cacao (Theobroma cacao L.) is one of the main strategies needed to increase the productivity of cacao beans. The main objective of this work is to verify the linear relationships, bivariate and multivariate analysis between the foliar nutrient concentrations of 48 cropping areas and graphic...
In cacao crop the understanding of the multiple relationships between bean and pod husk dry biomass and mineral nutrition in the soil-plant system is scarce. The main objective of this work is to verify the linear, bivariate and multivariate correlations between the mineral nutrient concentrations in the soil, leaves and beans of 53 cacao trees wit...
Brazil is increasingly committed to developing research on the quality of cacao. The objective of this work was to develop a new Cacao Quality Index (CQI) methodology with cacao industry, chocolate flavor, human health and food safety functions, and to show its results in different cacao agroecosystems from the humid region of Bahia. The typical Dy...
In the present technological context, the identification of substances that contribute to the quality of dry cacao (Theobroma cacao L.) beans is as important as the agricultural practices and processing of cacao beans for food safety and marketing. The objective of this study was investigating the influence of cropping sites, represented by differe...
The soil quality index (SQI) for cacao cropping systems was developed to meet the nutritional criteria of the crop, the environmental safety of the cropping sites and the increasing demand for the production and quality of cocoa. Available water function (AWF), root growth function (RGF), mineral nutrition of plants function (MNF) and environmental...

In view of its high economic value, cacao (Theobroma cacao L.) scientists are seeking technological innovations that increases production and improve quality of cacao beans. The objective of this study was to characterize the mineral (N, K, P, Ca, Mg, Si, Fe, Mn, Zn, Cu, Cd, Ba) composition of cacao beans of clone PH-16 grown in different soil type...
The countryside is characterized by dynamism of experiences by interpersonal relations and natural resources, where the places of production and social reproduction complement each other. The environment, through its physical and biotic components in their interactions and as a result of human actions, provides rural families, not just getting food...
This study aimed to investigate the influence of different sites of cacao (Theobroma cacao L.) cultivartion,
represented by different soils and cropping systems, on biometrics attributes of pods and beans. The 12 study sites are in the cacao region of Bahia, Brazil, in the humid zone. The variation and the statistical differences between the means...
World demand for cacao and the requirements for quality beans have increased every year. Research studies have developed standards for aspects of cacao quality that meet industrial criteria as well as international import and export legislation that is aimed at food security. This review focused on selected attributes of cacao bean quality. These a...
Livro que apresenta uma contribuição para o estudo de bacias hidrográficas no Brasil, em especial ao que se refere aos diferentes métodos e técnicas de pesquisa, atualmente utilizados por professores e pesquisadores da área. Os capítulos foram organizados de modo a abranger aspectos relevantes que envolvem a análise, planejamento e manejo de bacias...
The cacao, as part of the wonderful nature, provides the mankind a wide variety of valuable food products and health benefits. The most known and universally relished product derived from this fruit is chocolate, an amazing and unique food for the human nutrition with records of consumption of similar products dating to 1000 years B.C. In fact, the...
Information concerning the classification of soils and their properties under cacao agroforestry systems of the Atlantic rain forest biome region in the Southeast of Bahia, Brazil is largely unknown. Soil and climatic conditions in this region are favorable for high soil carbon storage. This study is aimed to classify soils under cacao agroforestry...
The objective of this study was to better understand the populational structure of juçara palm (Euterpe edulis Mart.) in the Southern Bahia Atlantic Forest, in the Ecoparque de Una, Una, BA, Brazil. The plants in the population were classified into one of six size classes: Seedlings, Juvenile I, Juvenile II, Immature I, Immature II, and Adult. For...
Organic matter may be considered an important soil quality indicator, as it is related with many soil chemical, physical, and biological characteristics. The study of total organic carbon (TOC) of the soil and its fractions is important. This study was conducted in a micro basin, with the purpose of: analyzing characteristics and quantify the stock...

O entendimento dos fatores e processos de formação do solo, bem como, a interpretação dos atributos resultantes da sua gênese reveste-se, muitas vezes, em tarefa árdua tanto para o professor quanto ao aluno. MARSHALL & HASEMAN (1942), sugeriram um método que se baseia na determinação quantitativa de cada camada do perfil do solo, utilizando um mine...
The lack of predictability in litter-mix studies may result from the low correlation between species number and the traits that drive the processes under observation. From the standpoint of litter-quality-dependent ecological processes, we propose that litter chemical qualities are functional traits and introduce a multivariate index of chemical di...
The water erosion is one of the main forms of soil degradation and it is highly affected by the soil cover and landscape slope. The objective of this work was to quantify the detachment rate and the soil loss due to water erosion under simulated rains in pastures, as well as to study the effect of land cover and the slope classes (< 9, 10-15, 25-30...

The Atlantic Forest has been deforested to the point that only about 7% of the original forest remains. Soil degradation, including loss of soil organic carbon (SOC), has often been associated with deforestation. In extensive areas previously occupied by Atlantic Forest the soil has a naturally compact subsoil horizon called the coeso. This layer c...
