(Editora UFLA, 2019-10)A challenge in the packaging and export of specialty coffees is to avoid green coffee bean storage and transport conditions that negatively affect the sensory quality of the roasted beans. The present study evaluated green ...
-
(Instituto Agronômico (IAC), 1950-09)In determinations made with a porometer it was verified that the stomatal opening of coffee leaves increases in size immediately after the leaves are detached from the plant (fig. 1). This fact indicates that the method ...
-
(Instituto Agronômico (IAC), 1951-04)The present paper discusses the amount of water lost by the soil through the transpiration of coffee plants and shade trees in shaded coffee plantation. All methods and techniques employed in the study of transpiration of ...
-
(Editora UFLA, 2016-07)A eficiência da aplicação foliar de determinados produtos sobre o cafeeiro, depende, na maioria das vezes, da cobertura da superfície foliar com o produto aplicado em forma de pulverização. Neste estudo, objetivou-se ...
-
(Universidade Federal Rural do Semi-Árido, 2021)Commercial exploitation of the coffee crop is one of the most important activities in the world’s agricultural sector. One of the main phytosanitary problems affecting the crop is the presence of Meloidogyne incognita. ...
