Technical and economic evaluation of different operating modes for mechanized fertilizer application in coffee plantations

Andrade, Alan Delon; Ferraz, Gabriel Araújo e Silva; Faria, Rafael de Oliveira; Barros, Murilo Machado de; Silva, Fábio Moreira da; Sarri, Daniele; Vieri, Marco (Editora UFLA, 2020)

The present study aimed to investigate the performance parameters and related costs of a machinery set composed of a tractor and a machine for fertilizers and soil correctives application, working in a coffee yard. It was ...
Technical and economic viability of manual harvesting coffee yield maps

Faria, Rafael de Oliveira; Silva, Fábio Moreira; Ferraz, Gabriel Araújo e Silva; Herrera, Miguel Angel Diaz; Barbosa, Brenon Diennevan Souza; Alonso, Diego José Carvalho; Soares, Daniel Veiga (Editora UFLA, 2020)

Precision coffee growing is a concept that implies the use of precision agriculture techniques in coffee plantations. For the coffee growing, the precision electronic resources coupled to the harvesters are very scarce. ...
The influence of natrural fermentation on coffee drink quality

Pereira, Leandro Ferreira Bernardes; Franco Junior, Kleso Silva; Barbosa, Camila Karen Reis (Editora UFLA, 2020)

Coffee quality refers to various methods used in farming, selective harvesting that assist in quality preservation and drying methods to be performed. Some drying methods that are being performed fermentation procedures ...
Ultrastructural damage in coffee seeds exposed to drying and to subzero (°C) temperatures

Coelho, Stefânia Vilas Boas; Rosa, Sttela Dellyzete Veiga Franco da; Clemente, Aline da Consolação Sampaio; Lacerda, Laura Nardelli Castanheira; Silva, Luciano Coutinho; Fantazzini, Tatiana Botelho; Ribeiro, Fernando Augusto Sales; Castro, Elisa de Melo (Editora UFLA, 2020)

During drying and freezing, protective mechanisms act to maintain seed physiological quality. Some of these mechanisms contribute to the integrity of cell membranes. The damage caused to cell membranes due to cell stress ...
