-
(Editora da Universidade Estadual de Maringá - EDUEM, 2024)Climate change and the expansion of agricultural lands to low-fertility soils have prompted studies on the effects of water and nutritional stress on nutrient uptake and use. This study aimed to evaluate the efficiency of ... -
(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 ...
-
(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, ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2023-04-28)A diagrammatic scale with five levels (0, 0.1 - 2.0, 2.0 - 6.0, 6.0 - 10, and 10 - 14) was developed and evaluated to measure the symptoms of heat injury in a coffee seedling canopy. The scale was constructed to increase ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2022-03-09)Coffee outturn can be defined as the ratio between the harvested coffee and its respective processed grains. This character is greatly influenced by genotypic and environmental effects, and in breeding programs your analysis ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2022-03-09)Chemical control is essential for efficient pest management in coffee crops. Application technologies should safely deliver insecticides to the target whilst protecting the environment, insecticide applicators, and consumers. ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2022-08-15)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, ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2019)The identification and interpretation of discrepant observations in sensory experiments are difficult to implement since the external effects are associated with the individual consumer. This fact becomes more relevant in ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2019)In most cases, in genetic breeding of Arabica coffee, plot size is defined in an empirical manner. It is often based only on the experience of the breeders and the availability of resources, potentially leading to a reduction ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2019)The leaf area index (LAI) is relevant in studies of phenomena at different scales, such as for the leaf to canopy scale and the calculation of the extinction coefficient of photosynthetically active radiation (kPAR), ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2021)This study aimed to evaluate the beverage quality of Coffea canephora genotypes in different environments of the western Amazon to assist plant selection and new cultivar development. To analyze beverage quality, samples ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2020)Trait selection is occasionally necessary to save money and time, as well as accelerate breeding program processes. This study aimed to propose two criteria to select traits based on a Procrustes analysis that are poorly ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2019)Knowledge on the dynamics of micronutrients in coffee tree assists nutritional diagnosis and fertilization management. Therefore, the objective of this study was to evaluate the concentration and accumulation of micronutrients ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2007-10)Já existe um acervo de experiências práticas de transição agroecológica para a cultura do cafeeiro (Coffea arabica L.) em pequenas propriedades na região sul de Minas Gerais que inspiraram essa pesquisa. O experimento foi ...

Caracterização física e sensorial do café produzido nas condições topoclimáticas de Jesuitas, Paraná(Editora da Universidade Estadual de Maringá - EDUEM, 2008-07)A variação das condições climáticas interfere na formação e na maturação dos frutos, alterando suas características intrínsecas, as quais podem permitir diferentes qualidades de bebida, com potencial de produção de café ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2009-04)Visando reduzir o período de recuperação das lavouras após a recepa, neste trabalho objetivou-se avaliar a influência de diferentes lâminas de irrigação e do parcelamento da adubação sobre o crescimento do cafeeiro. Foram ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2009-04)Objetivou-se com o presente trabalho estimar e avaliar as curvas de secagem do café da espécie Coffea Canephora e ajustar diferentes modelos matemáticos aos valores experimentais de quatro clones. Foram utilizados frutos ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2009-01)O presente trabalho teve como objetivo avaliar os teores de trigonelina, ácidos clorogênicos (5-ACQ) e cafeína em grãos de diferentes cultivares de cafeeiro (Coffea arabica L.). As cultivares avaliadas foram coletadas na ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2009-01)Para avaliar a dose e a forma de aplicação de sulfato de zinco foliar no crescimento e produtividade do cafeeiro Mundo Novo, instalou-se um experimento de campo em LATOSSOLO VERMELHO Distroférrico, na Fazenda Experimental ...
