Resumo: In mechanized harvesting, one of the difficulties encountered by farmers is to determine the appropriate time to start harvesting, as well as vibration and determine the most appropriate operating speed for each cultivar during the harvest period. In general, the regulation of vibration and operating speed of the harvester has been made by producers in an empirical way, by trial, seeking greater operational performance. This study aimed to evaluate the efficiency of mechanical harvesting of eight progenies according to the traction force required for detachment of the fruit. The tests were conducted with three replications using a completely randomized design (CRD) within the same plot in random plots containing five plants. We tried to raise the strength of detachment from coffee fruits on the plant, according to the ripening of fruits, and graded to determine the strength, the green fruits and cherries. We also evaluated the efficiency of the harvest in the progenies analyzed over two years of harvest. It was concluded that there are significant differences between progenies in both the force of detachment as tothe efficiency of picking and that picking efficiency is directly related to the force of detachment of mature fruits on the plant.

De modo geral, a regulagem da vibração e da velocidade operacional das colhedoras tem sido feita pelos produtores de modo empírico, por tentativas, buscando o maior desempenho operacional. Objetivou-se, neste trabalho, avaliara eficiência de colheita mecanizada em oito progênies de acordo com a força de tração necessária para o desprendimento dos frutos. Os ensaios foram realizados com três repetições, utilizando-se o delineamento inteiramente casualizado (DIC) dentro de uma mesma gleba, em parcelas aleatórias ,contendo cinco plantas. Buscou-se levantar a força de desprendimento dos frutos de café na planta, de acordo com a maturação dos frutos, sendo classificados, para a determinação da força, os frutos verdes e cerejas. Também foi avaliada a eficiência de colheita nas progênies analisadas em dois anos de safra. Concluiu-se que há diferença significativa entre as progênies avaliadas tanto na força de desprendimento como na eficiência de colheita e que a eficiência de colheita está relacionada diretamente com a força de desprendimento dos frutos maduros na planta.Editora UFLA2013-04-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfimage/tiffapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documentapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/345Coffee Science - ISSN 1984-3909; Vol. 8 No. 1 (2013); 53-60Coffee Science; Vol. 8 Núm. 1 (2013); 53-60Coffee Science; v. 8 n. 1 (2013); 53-601984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAengporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/345/pdf_114https://coffeescience.ufla.br/index.php/Coffeescience/article/view/345/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/345/1034https://coffeescience.ufla.br/index.php/Coffeescience/article/view/345/1035https://coffeescience.ufla.br/index.php/Coffeescience/article/view/345/1036https://coffeescience.ufla.br/index.php/Coffeescience/article/view/345/1037Copyright (c) 2013 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessda Silva, Flávio Castroda Silva, Fábio Moreirada Silva, Antônio Carlosde Barros, Murilo MachadoZambillo Palma, Marcos Antônio2014-08-25T17:56:24Zoai:coffeescience.ufla.br:article/345Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:38.264980Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
