Active and passive chlorophyll fuorescence measurements at canopy level on potato crops. Evidence of similitude of diurnal cycles of apparent fuorescence yields
(Photosynthesis Research, 2022)
We performed active and passive measurements of diurnal cycles of chlorophyll fuorescence on potato crops at canopy level in outdoors conditions for 26 days. Active measurements of the stationary fuorescence yield (Fs) ...
Effects of agro-forestry systems on the physical and chemical characteristics of green coffee beans
(Frontiers, 2023-07-12)
A study at CATIE, Costa Rica, examined 20 agroforestry systems for coffee plantations, testing different management practices and shade types. Physical and chemical attributes of green coffee beans were analyzed. Full sun ...
Ethnobotanical Knowledge of Edible Plants Amongst Children from Two Rural Communities in Western Mexico
(Springer, 2023-03-15)
Ethnobotanical knowledge, also known as Local Ecological Knowledge (LEK), of edible plants includes identifying plants using local names and knowledge of specific preparations and ecological characteristics. We analyze ...
Structure, diversity and the conservation value of tropical dry forests in highly fragmented landscapes
(Journal of Plant Ecology, 2022-03-09)
Although tropical dry forests are among the most degraded and fragmented biomes in the world, we still have a poor understanding of their basic ecological features and conservation status, particularly in the Neotropics. ...
Water Saving Using Thermal Imagery-Based Thresholds for Timing Irrigation in Potatoes under Drip and Furrow Irrigation Systems
(Agronomy, 2022)
Under the current water crisis in agriculture, irrigation methods for saving and conserving water are necessary. However, these methods must guarantee an appropriate yield with a concomitant economic benefit and a reduced ...
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 ...
A review of wildfires effects across the Gran Chaco region
(Forest Ecology and Management, 2023-12-01)
The main objective of this review paper is to synthesize studies related to fire occurrence, the effects of fire on native vegetation at the Gran Chaco scale, and changes in fire regimes, in order to identify current ...
Influence of Fermentation Time on the Chemical and Functional Composition of Different Cocoa Clones from Southern Colombia
(MDPI, 2023-11-16)
Cocoa bean quality depends mainly on genetic material, edaphoclimatic factors and post-harvest processes such as fermentation. The impact of the fermentation process on the chemical and functional composition of different ...
Shade canopy density variables in cocoa and coffee agroforestry systems
(Springer Nature, 2023-12-18)
An estimated 3.4 million hectares of cocoa and 9.7 million hectares of coffee are cultivated, globally, under shade trees, i.e. in agroforestry systems. Shade canopies are characterized in terms of tree density (N, trees ...
