(Editora UFLA, 2014-09)Weed control in different crops affects the chemical, physical, and biological properties of the soil and consequently its structural quality. The objective of this study was to evaluate, using water retention characteristics ... -
(Associação Brasileira de Engenharia Agrícola, 2013-03)The increasing demand for water resources accentuates the need to reduce water waste through a more appropriate irrigation management. In the particular case of irrigated coffee planting, which in recent years presented ...
-
(Associação Brasileira de Tecnologia de Sementes - ABRATES, 2018)The aim of this study was to evaluate the effect of water stress on the germination of Coffea arabica seeds and the growth and development of plants from these seeds. Seeds of the cultivars Bourbon Vermelho, Mundo Novo, ...
-
(Editora da Universidade Estadual de Maringá - EDUEM, 2014-07)Many coffee growers apply glyphosate in directed applications, but some phytotoxicity has been noted. It is believed some herbicides can exert a direct or indirect negative effect on photosynthesis by reducing the metabolic ...
-
(Universidade Federal de Lavras, 2022-12-29)The energy dissipation and the evapotranspiration processes, are factors involved in the ecosystem net carbon exchange and are determinants in the ability of a self-regulating system to balance high carbon emissions. To ...
-
(Universidade Federal do Ceará, 2016-04)The aim of this work was to evaluate the use of a water-retaining polymer on the initial growth of coffee plants for different levels of irrigation and types of seedling. The experiment was set up in pots with a clayey ...
-
(Sociedade Brasileira da Ciência das Plantas Daninhas, 2004-10)This study was carried out to investigate the efficiency of several herbicides under field conditions, by post-emergence application onto the entire area, their effect on the control of weeds in young coffee plantations ...
-
(Editora UFLA, 2009-07)Weed management is identified as a major cause of soil compaction in coffee plantations, because of its necessary frequent undertaking. The objectives of this study were: a) to develop bearing capacity models, for a ...
-
(Editora UFLA, 2018-01)Knowledge of the wet bulb and the root system of the Conilon coffee plant is highly important for the correct management of irrigation. Therefore, the aim of this work was to characterize the wet bulb and Conilon coffee ...
-
(Instituto Internacional de Ecologia, 2010)Stomata are crucial in land plant productivity and survival. In general, with lower irradiance, stomatal and epidermal cell frequency per unit leaf area decreases, whereas guard-cell length or width increases. Nevertheless, ...
-
(Universidade Federal Rural do Semi-Árido, 2021)Little is known about the management of high-yield clonal Coffea canephora in the Amazonian Region, mainly for nutritional aspects and cultivation system efficiency. This study aimed to evaluate the influence of different ...
-
(Universidade Federal de Santa Maria, 2021)This study evaluated the occupational exposure of workers to heat during manual harvesting of coffee. The case study was conducted between May to August. Occupational heat in coffee plantations was evaluated using the Wet ...
-
(Universidade Federal do Ceará, 2013-10)The conilon coffee tree presents high yield potential, the replacement of soil nutrients usually being by the use of mineral fertilizers. To reduce these fertilizers, the use of organic waste may be an alternative. The ...
-
(Sociedade Brasileira de Ciência do Solo, 2014-05)Inconclusive responses of the adult coffee plant to phosphorus fertilization have been reported in the literature, especially when dealing with application of this nutrient in high density planting systems. Thus, this study ...
-
(Editora UFLA, 2019-07)The total of three consecutive years of fruit production was evaluated in six coffee cultivars (Coffea arabica L.) propagated by seed and grafted onto Robusta (Coffea canephora var. Robusta). The plantations were established ...
-
(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2021-12-10)The objective of this work was to determine the contribution of the number of stems to the composition of individual plant yield, and to individual and overall robusta coffee (Coffea canephora) yield at different planting ...
-
(Escola Superior de Agricultura "Luiz de Queiroz", 2010-11)Coffee (Coffea Arabica L.) plantations using adapted cultivars to regional environmental conditions with optimal plant population density and adequate nutrition are expected to show high yield responses. The triennial ...
-
(Crop Breeding and Applied Biotechnology, 2019)Eighty-five Coffea canephora genotypes were evaluated for three crop seasons under irrigation in the Cerrado of the Distrito Federal, Brazil, to characterize the population regarding phenotype, yield and maturation cycle. ...
-
(Editora UFLA, 2018-07)In this study the goal was to make an assessment and comparison of the yield, quality and water consumed by the Conilon coffee plants under irrigated and dryland types of cultivation, from seedlings raised in different ...
-
(Editora UFLA, 2021)This research focused on the study of young coffee leaves as a potential source of caffeic acid from the biotransformation of abundant chlorogenic acid. Aspergillus oryzae was isolated from koji rice and used for the ...
