Estimación de las concentraciones relativas de clorofila en foliolos de papa (solanum tuberosum l.) utilizando técnicas de reflectancia de la vegetación
(2023-01-06)
La cantidad de energía solar absorbida por una hoja es en gran parte función de la concentración foliar de los pigmentos fotosintéticos. Por lo tanto, bajas concentraciones de clorofila pueden limitar el potencial fotosintético ...
About identification of features that affect the estimation of citrus harvest
(2023-06-27)
Accurate models for early harvest estimation in citrus production generally involve expensive variables. The goal of this research work was to develop a model to provide early and accurate estimations of ...
Risk analysis and cacao pod survivorship curves to improve yield forecasting methods
(Frontiers, 2024-03-22)
Cocoa attainable yields are affected by a complex of pests and diseases in a particular agro-environment. Estimation of yield loss is critical for agronomic and economic decision-making at the farm level. For over 15 months, ...
Interactions between climate, shade canopy characteristics and cocoa production in Colombia
(Frontiers, 2024-02-09)
Properly designed agroforestry systems (AFS) can generate optimal cocoa bean (BC) yields, produce co-products and provide ecosystem services. This study analyzes the interactions between climate, AFS structure and BC yield ...
Cadmium concentration in cocoa beans produced in agroforestry systems of small producers in Panama
(CSIC, 2024-01-30)
Aim of study: To calculate Cd concentration in cocoa plants and evaluate its relationship with available Cd and other soil properties. Area of study: Almirante, Bocas del Toro province, Panama, in 2020-2021. Material and ...
A combination of conserved and diverged responses underlies Theobroma cacao’s defense response to Phytophthora palmivora
(BMC Biology, 2024)
Plants have complex and dynamic immune systems that have evolved to resist pathogens. Humans have worked to enhance these defenses in crops through breeding. However, many crops harbor only a fraction of the genetic diversity ...
Milk production systems in Latin America and the Caribbean: Biophysical, socio-economic, and environmental performance.
(Elsevier Ltd., 2024)
The Latin America-Caribbean (LAC) region has the potential to pursue a sustainable expansion of
livestock production and capitalise on the growing global demand for dairy and beef products. However, it is
This study ...
Diversity and productive potential of timber trees in cocoa agroforestry systems in Alta Verapaz, Guatemala
(Revista de la Facultad de Agronomía de la Universidad del Zulia, 2024-02-27)
Timber production in agroforestry systems can improve environmental and economic sustainability, especially for families living in rural areas. Despite its importance in Guatemala, little is known about ...
Haitian coffee agroforestry systems harbor complex arabica variety mixtures and under recognized genetic diversity
(University of Jeddah, 2024-04-16)
Though facing significant challenges, coffee (Coffea arabica) grown in Haitian agroforestry systems are important contributors to rural livelihoods and provide several ecosystem services. However, little is known about ...
Tropical forest succession increases taxonomic and functional tree richness but decreases evenness
(Wiley, 2024-06-08)
Successional changes in functional diversity provide insights into community assembly by indicating how species are filtered into local communities based on their traits. Here, we assess successional changes in taxonomic ...
