(Instituto Internacional de Ecologia, 2023-11-03)Coffea sp. is cultivated in many tropical countries. Brazil has always adopted intensive agricultural practices, but organic coffee farming is an alternative system based on the non-use of agrochemicals and the rational ... -
(Academia Brasileira de Ciências, 2021-04-09)Geographic information systems make it possible to obtain fine scale maps for environmental monitoring from airborne sensors on aerial platforms, such as unmanned aerial vehicles (UAVs), which offer products with low costs ...
-
(Instituto Internacional de Ecologia, 2023-09-18)Coffea sp. é cultivada em muitos países tropicais. O Brasil sempre adotou práticas agrícolas intensivas, mas a cafeicultura orgânica é um sistema alternativo baseado na não utilização de agrotóxicos e no manejo racional ...
-
(Instituto Internacional de Ecologia, 2023)The use of residues from coffee production to obtain biochar is a sustainable approach, which aims to minimize the environmental impact of these materials. In this study, the effect of adding coffee straw biochar on the ...
-
(Instituto Internacional de Ecologia, 2023-03-30)Considered the economic engine of many countries, the coffee culture represents an important component of the agricultural chain in Brazil. The growing values of commercialization, planting areas, and crop productivity ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2024-01-12)The use of computational simulation techniques is an important tool for the coffee harvesting issues, particularly the finite element method. The method is widely used in the structural analysis of agricultural machinery, ...
-
(Revista Engenharia na Agricultura, 2009-08-19)A redução da temperatura da massa de grãos, abaixo de 15 ºC tem sido eficiente para reduzir a atividade de água dos grãos e, consequentemente, a atividade de insetos e de fungos. Objetivou-se, com esse trabalho, resfriar ...
-
(Academia Brasileira de Ciências, 2023-06-16)Coffee, one of the most produced and consumed beverage in the world, has a range of variability in its quality. The aim of this work was to evaluate the consumer capacity to perceive the coffee quality through their fragrance ...
-
(Instituto Agronômico (IAC), 2021-09-13)The agricultural use of biochar has been the focus of much research in the last decade due to the improvement of soil chemical, physical, and biological attributes. Nonetheless, Brazil still has no specific legislation for ...
-
(Instituto Biológico, 2023-10-03)Among the management and control tactics of the coffee berry borer Hypothenemus hampei (Ferrari), there is the use of entomopathogenic fungi. Due to the importance of prospecting isolates of entomopathogenic fungi for the ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2024)Most coffee (Coffea arabica) phytosanitary management techniques are performed using ground-based equipment, and remotely piloted aircraft are a recent alternative. Therefore, this study evaluates the effect of different ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2023)The reduced longevity of coffee seeds has been attributed to their sensitivity to desiccation. Studies related to gene expression and enzyme activity in coffee seeds under drying are important for understanding the effects ...
-
(Instituto Agronômico (IAC), 2024-03-21)The objective of this study was to evaluate the physiological quality of seeds from early and late maturing Coffea canephora clones, aiming to identify the ideal harvest time. The fruits were collected every two weeks from ...
-
(Instituto Agronômico (IAC), 2024-05-09)The physical and chemical attributes of coffee beans have a direct relation with the sensory quality of the beverage and the commodity’s market value. The coffee berry borer is a pest that causes a worldwide harm, and its ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2021-03-09)Intensive weed management is one of the most common practices in coffee cultivation areas. Consequently, some problems, such as soil degradation and the selection of herbicide resistant weed, have increased over time, but, ...
-
(Universidad Nacional de Colombia, 2023-10-09)This study aimed to assess and compare the behavior of superior genotypes of Coffea canephora in terms of fruiting capacity using directed hybridizations in a full diallel design with reciprocals.Hybridizations were performed ...
-
(Revista Brasileira de Agropecuária Sustentável, 2020-03-03)A cafeicultura tem grande importância econômica no território nacional, entretanto, enfrenta algumas limitações no seu manejo, principalmente na sua implantação, pelo fato de comprometer todo o processo produtivo. A ...
