“…More simply, to improve the production of these systems, remove trees that are currently unproductive and replant them with plants that are better able to grow and produce in this environment. Alternatively, rehabilitation of some trees may be envisaged, through rejuvenation pruning or grafting of adapted and productive genetic material on shoots or branches (Djuideu et al 2021).…”

Knowledge is lacking on the effects of associated crops on cocoa productivity in complex cocoa-based agroforestry systems. Through a generalized linear mixed model, we analyzed the influence of (i) the density and (ii) the height of associated species on cocoa tree productivity along a distance gradient of 0 to 5 m between cocoa trees and associated plants. We mapped 34 mature agroforestry systems in farmers' plots to locate the position of different crop species in relation to each other. The production of each plant was monitored at fortnightly intervals over one year. The main results showed that cocoa tree productivity increased in the presence of Fabaceae, even when at a short distance (< 3 m), and to a lesser extent in the presence of timber trees. All the other species, i.e., food-producing trees, had a negative effect on cocoa productivity, which diminished with increasing distance up to a distance ranging from 3 to 5 m depending on the species. The height of associated plants also had a significantly negative effect on cocoa productivity at a distance of less than 3 m, beyond which the negative effect decreased. To our knowledge, it is the first study that finely analyzes the effect of associated crops on cocoa productivity according to farmers' use and for short distances. These results are of particular interest for the structural redesign of agroforestry systems, in order to optimize their agro-economic performance, and can be used to recommend the distance to be respected between cocoa trees and associated plants as well as the height of the different crops or forest trees.

“…Several species of Coptotermes are known to target living trees [40], including C. gestroi, which is present in Puerto Rico [41]. Termites are a major constraint to cacao production in Africa, where their negative impacts on yield and tree survival have been extensively documented [42][43][44][45].…”

Fungal Pathogens of Cacao in Puerto Rico

Cacao production is a rapidly expanding industry in Puerto Rico, with new farmers planting ~20,000 trees in the past few years. To determine the etiology and extent of diseases affecting cacao in Puerto Rico, a survey was performed at eight sites around the island. Pod rot and/or branch dieback were observed at all sites. Most organisms isolated from symptomatic pod and stem samples were identified as Diaporthe spp. (48%) and Lasiodiplodia spp. (25%) based on sequences of the internal transcribed spacer and large subunit regions. Within these genera, Diaporthe tulliensis and Lasiodiplodia theobromae were the most prevalent species and were used in inoculation studies to determine their relative virulence on pods and stems. Phytophthora palmivora served as a positive control due to its well-established pathogenicity in all tissues. On pods, L. theobromae and P. palmivora caused significantly larger lesions (6.1 and 5.9 cm, respectively) than D. tulliensis (2.7 cm) four days post-inoculation. All three species caused disease on stems, with no differences found among species. Although P. palmivora was thought to be the primary pathogen affecting cacao in Puerto Rico, this study identifies L. theobromae and D. tulliensis as the common pathogens on the island. This improved understanding will help scientists and farmers control disease by selecting fungicides effective against both oomycetes and fungi.

“…Diversas alternativas têm sido propostas para manter o equilíbrio econômico do mercado cacaueiro preservando a biodiversidade local, como a diversificação da produção e, no caso da agricultura familiar, o uso de sistemas agroflorestais. capacidade e, independentemente do cenário atual, a tendência aponta para uma demanda crescente por chocolate com alto teor de cacau e produtos com experiências diferenciadas de consumo (Djuideu et al, 2021).…”

O cacau é um dos produtos agrícolas mais importantes do mundo, possui uma cadeia produtiva bem estabelecida e o Brasil é um dos maiores produtores mundiais. É considerado uma matéria-prima viável para produção de alimentos funcionais, devido aos seus altos níveis de substâncias bioativas e antioxidantes. Sendo assim o estudo tem como objetivo conceituar o cacau em termos de origem, produtividade, impacto na saúde, inovação na indústria de alimentos além da viabilidade da sua aplicação em produtos lácteos caprinos através de uma revisão bibliográfica narrativa. A abordagem metodológica permitiu o uso de estudos experimentais e não experimentais para ter uma compreensão completa sobre a temática proposta. A pesquisa foi realizada na base do ScienceDirect, Scielo, Web of Science, SCOPUS e Schollar Google se restringindo a estudos de livre acesso publicados de 2019 a 2023 usando “cocoa”, “healthy”, “dairy”, “goat milk” como palavras-chave. Através do estudo foi possível analisar a cadeia produtiva do cacau se tratando do panorama mundial, compreendendo que apesar da pandemia do covid-19 o cacau continua relevante, promissor e com demanda no mercado. Utilizando o mesmo como base é possível desenvolver uma gama de produtos com alto teor de compostos bioativos trazendo assim benefícios a saúde do consumidor. Também pode-se constatar a viabilidade da adição de cacau associado a outras substâncias probióticas e prebióticas em produtos lácteos caprinos, resultando assim em produtos acessíveis a sociedade com características nutricionais e sensoriais satisfatórias.
