  • Litterfall decomposition of coffee shaded with Tectona grandis or in full sun
    Henrique, Nirvani S.; Maltoni, Katia L.; Faria, Glaucia A. (Departamento de Engenharia Agrícola - UFCG, 2022-01-14)
    Litterfall is an important source of soil nutrients, but its decomposition can be affected by the crop system used. The objective of this study was to evaluate litterfall decomposition and macronutrient stocks in coffee ...
  • Mechanized harvesting of conilon coffee plants using a self-propelled machine
    Souza, Gustavo S. de; Bouzan, Antônio M. B.; Infantini, Maurício B.; Silva, Samuel de A.; Almeida, Robson F. de (Departamento de Engenharia Agrícola - UFCG, 2022-10-24)
    Coffee is one of the main commodities of global agribusiness and of outstanding economic and social relevance for Brazil. The lack of labor and its high cost are factors that worry coffee producers, mainly during the conilon ...
  • Nutritional balance and its relationship to yield in a coffee field: Inferences from geospatial analysis
    Silva, Marcelo B. da; Partelli, Fábio L.; Gontijo, Ivoney; Caldas, Marcellus M. (Departamento de Engenharia Agrícola - UFCG, 2020)
    Information obtained from studies of spatial variability and the Diagnosis and Recommendation Integrated System (DRIS) may contribute to understanding better the relationship between mineral nutrient balance and factors ...
  • Preservation of roasted and ground coffee during storage Part 1: Moisture content and repose angle
    Corrêa, Paulo C.; Oliveira, Gabriel H. H. de; Oliveira, Ana P. L. R. de; Vargas-Elías, Guillermo A.; Santos, Fábio L.; Baptestini, Fernanda M. (Departamento de Engenharia Agrícola - UFCG, 2016-06)
    The present study evaluates the influence of the level of roasting and the grind size on the moisture content and repose angle of coffee during storage. Raw coffee beans (Coffea canephora and Coffea arabica), hulled and ...
  • Preservation of roasted and ground coffee during storage. Part 2: Bulk density and intergranular porosity
    Corrêa, Paulo C.; Oliveira, Gabriel H. H. de; Vasconcelos, Wander L.; Vargas-Elías, Guillermo A.; Santos, Fábio L.; Nunes, Eduardo H. M. (Departamento de Engenharia Agrícola - UFCG, 2016-07)
    The determination of physical properties is an important factor in the design of machinery and the scaling of post-harvest operations. The present study evaluates the influence of the level of roasting and the size of ...
  • Soil quality in two coffee crop systems in the Amazon biome
    Henrique, Nirvani S.; Maltoni, Katia L.; Faria, Glaucia A. (Departamento de Engenharia Agrícola - UFCG, 2020)
    The form of occupation of the state of Rondônia, Brazil, favored the extensive agriculture, which resulted in a fast deforestation. The removal of forests and inadequate soil management and use, combined with a hot and wet ...
