Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica
(2020)
Coffee leaf rust is a polycyclic disease that causes severe epidemics impacting yield over several years. For this reason, since the 1960s, more than 20 models have been developed to predict different indicators of the ...
Unraveling Ecophysiological Mechanisms in Potatoes under Different Irrigation Methods: A Preliminary Field Evaluation
(2020)
Potatoes—a global food security and staple crop—is threatened by dry spells in drought-prone areas. The use of physiological thresholds to save water while maintaining a reasonable tuber yield has been proposed, but their ...
Do Coffee Agroforestry Systems Always Improve Soil Carbon Stocks Deeper in the Soil?—A Case Study from Turrialba, Costa Rica
(2020)
Shaded perennial agroforestry systems (AFS) are regarded as desirable land-use practices that improve soil carbon sequestration. However, most studies assume a positive correlation between above ground and below ground ...
Biodiversity and the livestock sector - Guidelines for quantitative assessment
(2020)
The Technical Advisory Group (TAG) on biodiversity, hereafter called Biodiversity TAG, is composed of 25 international experts in ecology, biodiversity indicators, agronomy, life cycle assessment, livestock production ...
A single polyploidization event at the origin of the tetraploid genome of Coffea arabica is responsible for the extremely low genetic variation in wild and cultivated germplasm
(2020)
The genome of the allotetraploid species Coffea arabica L. was sequenced to assemble independently
the two component subgenomes (putatively deriving from C. canephora and C. eugenioides) and
to perform a genome-wide ...
Assessing the accuracy and robustness of a process-based model for coffee agroforestry systems in Central America
(Springer, Nueva York (Estados Unidos), 2020)
Coffee is often grown in production systems associated with shade trees that provide different ecosystem services. Management, weather and soil conditions are spatially variable production factors. CAF2007 is a dynamic ...
Agronomic conditions of cacao cultivation: its relationship with the capitals endowment of Colombian rural households
(Springer, Nueva York (Estados Unidos), 2020)
Abstract Cacao cultivation has great socioeconomic importance for the development of rural areas of Colombia, especially for the approximately 52,000 rural households that depend on it. Therefore, is important to analyze ...
Accurate Differentiation of Green Beans of Arabica and Robusta Coffee Using Nanofluidic Array of Single Nucleotide Polymorphism (SNP) Markers
(2020)
Green (unroasted) coffee is one of the most traded agricultural commodities in the world. The Arabica (Coffea arabica L.) and
Robusta (Coffea canephora Pierre ex A. Froehner) species are the two main types of coffees for ...
Economic constraints as drivers of coffee rust epidemics in Nicaragua
(Elsevier, Ámsterdam, Países Bajos, 2020-10)
Coffee rust (Hemileia vastatrix) epidemics of an intensity never seen before have hit Central America since 2012. This study set out to identify management and socio-economic factors that facilitate coffee rust development ...
