Fruit thinning and shade improve bean characteristics and beverage quality of coffee (Coffea arabica L.) under optimal conditions
Under two contrasting light regimes and the optimal coffee-growing conditions of the central valley of Costa Rica, production pattern, bean characteristics and beverage quality were assessed over two production cycles on dwarf coffee trees with varying fruit loads imposed by manual fruit thinning.

Homeostasis of the hybrids for which bean biochemical composition was less affected by elevation than that of the traditional varieties is confirmed, which should act as a catalyst in increasing the economic viability of coffee agroforestry systems being developed in Central America. Expand
Effects of Inga densiflora on the microclimate of coffee (Coffea arabica L.) and overall biomass under optimal growing conditions in Costa Rica
Investigating the impact of Inga densiflora, a very common shade tree in Central America, on the microclimate, yield and vegetative development of shaded coffee in comparison to coffee monoculture found Inga-shaded plantations appeared more advantageous than MC in optimal conditions. Expand
Trade-offs between crop intensification and ecosystem services: the role of agroforestry in cocoa cultivation
Research published in this special issue on cocoa agroforestry illustrates the multifunctional role of shade trees for sustaining cocoa production and improving farmers’ livelihoods, and addresses… Expand

Côte d’Ivoire produces 40 % of the world supply of cocoa but much of the plantation area is aging and declining in productivity, while opportunities for land expansion into new forest land are… Expand
Fruit load and branch ring-barking affect carbon allocation and photosynthesis of leaf and fruit of Coffea arabica in the field.
Increasing fruit load significantly decreased branch growth on 5-year-old coffee trees of the dwarf cultivar 'Costa Rica 95', during their third production cycle, illustrating the importance of berry sink strength and indicating that there is competition for carbohydrates between berries and shoots and also among berries.

Leaf area index as an indicator of ecosystem services and management practices: An application for coffee agroforestry
Abstract Scalable indicators are promising to assess ecosystem services. In a large (660 ha) coffee agroforestry farm, we calibrated the relationship between the Normalized Difference Vegetation… Expand
Shade: A key factor for coffee sustainability and quality
For the last 5 years, research has been undertaken on associations of coffee and shade trees in Central America to promote coffee agroforestry systems in the region and to improve coffee farmers'… Expand
Soluble sugars mediate sink feedback down-regulation of leaf photosynthesis in field-grown Coffea arabica.
Amax was closely related to SSCm by a nonlinear equation that may be useful for integrating sink limitations in coffee leaf photosynthetic models, indicating that down-regulation of Amax is related to phloem sucrose concentration in coffee source leaves, independent of SSCM concentration in other leaf tissues.

Competition for light in heterogeneous canopies: Application of MAESTRA to a coffee (Coffea arabica L.) agroforestry system
In agroforestry systems (AFS), quantifying the competition for light is a prerequisite toward understanding the impact of shade trees on the productivity of the under-crop. Models for homogeneous… Expand
