(Associação Brasileira de Engenharia Agrícola, 2021)An adequate combination of factors involved in the technology used for phytosanitary product application contributes to an efficient spray deposition on the target. The objective of this study was to use multivariate ...
-
(Associação Brasileira de Engenharia Agrícola, 2021)There exist two options for digital cameras that can capture the near-infrared (NIR) band. Conventional red–green–blue (RGB, visible bands) cameras with a single sensor provide NIR band visibility based on the removal of ...
-
(Associação Brasileira de Engenharia Agrícola, 2021)This study aimed to evaluate the performance of the infrared spectrum in the range of 4000−650 cm−1 for characterizing and differentiating dried and ground coffee cherry pulp of different varieties. The spectral data were ...
-
(Associação Brasileira de Engenharia Agrícola, 2020)Numerous factors are related to the individual sensory perception of consumers, which makes it impossible to adapt a model that explains their behavior. In this context and given the scarcity of statistical indexes that ...
-
(Associação Brasileira de Engenharia Agrícola, 2020)Coffee growers who produce the robusta species (Conilon) have sought to increase productivity and drink quality by improving production techniques. Artificial vision systems can assist in increasing the efficiency of ...
-
(Associação Brasileira de Engenharia Agrícola, 2020)This study aimed to evaluate drying kinetics for natural and pulped coffee, using diferente temperatures and drying airflows. For the conduction of the experiment, coffee fruits (Coffea arabica L. cv. Topázio) were harvested ...
-
(Associação Brasileira de Engenharia Agrícola, 2020)The objective of this work was to study the influence of two postharvest processing methods on the biochemical composition and sensory analysis of a Colombian specialty coffee. For this purpose, coffee beans (Coffea arabica) ...
-
(Associação Brasileira de Engenharia Agrícola, 2020)The aim of this study was to evaluate and model the hygroscopic equilibrium and isosteric heat curves of pericarp and endosperm tissues of arabica (Coffea arabica) coffee fruit, in different temperature and relative humidity ...
-
(Associação Brasileira de Engenharia Agrícola, 2019)Tree crops, such as Arabica coffee (Coffea arabica L.), present enormous technical challenges in terms of pesticide application. The correct deposition and distribution of the active ingredient throughout the aerial part ...
-
(Associação Brasileira de Engenharia Agrícola, 2019)Grain drying processes have been improved to reduce costs and losses of coffee beverage quality. The objectives of this study were to evaluate the quality of coffee dried using air partially dehumidified before entering ...
-
(Associação Brasileira de Engenharia Agrícola, 2019)This work aimed to study the immediate and latent effects of different relative humidities on the quality of dried coffee fruits, describe the drying kinetics of natural immature coffee (Coffea arabica L.), and evaluate ...
-
(Associação Brasileira de Engenharia Agrícola, 2019)Agricultural spray adjuvants (ASA) are widely used in pesticide applications to enhance the performance of pesticides. The aim of this research was to investigate the effects of ASA on static surface tension (SST) and ...
-
(Associação Brasileira de Engenharia Agrícola, 2018-11)In recent years, the coffee has undergone major changes, and in case of transplanting operation, the use of machinery has proved to be a viable alternative to producers. Prior knowledge of the influence of the variables ...
-
(Associação Brasileira de Engenharia Agrícola, 2018-09)The elaboration of maps to characterize the spatial variability of soil attributes assists in the strategic planning and decision making of agricultural managers. Precision and accuracy of maps are related to the ideal ...
-
(Associação Brasileira de Engenharia Agrícola, 2018-09)The plant water potential and the leaf temperature are physiological responses of the coffee tree that can be used as indicative of the irrigation management of this crop. There is a dependence between the leaf water ...
