Resumo: Due to the importance of coffee to the economy of Brazil and the increase of areas even in zone with water deficits during the year, it is necessary to study the factors involved in its production, especially for mechanized and selective harvesting. At this stage coffee farmers find it difficult to determine the appropriate time to start. This research was carried out to evaluating the spatial variation of force detachment of the coffee fruits (green and cherry) under center pivot through geostatistical methods, semivariogram analysis and kriging interpolation, to improve management for harvest mechanical and selective coffee. The test was carried out at Farm Sao Joao Grande, in Presidente Olegario/MG, in a pivot 50.0 ha. The cultivar used was the “Catuai Vermelho IAC 144”, planted in a circular way in December 2000, spaced 4.0 x 0.5 m. The sampling grid was irregular with 100 points georeferenced where each point corresponds to 4 plants. The determination of force detachment was conducted using a digital dynamometer at each sampling point. Within the maturation stages, green fruits presented detachment force greater than the cherry. The semivariogram and kriging allowed to characterize the variability of force detachment between the studied fruits. The kriging maps make it possible to farmers the choice the best place and the right time to start harvest mechanized and selective coffee and consequently, improved final product quality and profits.

Este trabalho foi conduzido com o objetivo de avaliar a variação espacial da força de desprendimento dos frutos de café (verde e cereja) sob pivô central, por meio de métodos geoestatísticos, análise de semivariograma e interpolação por krigagem, visando uma melhor gestão para a colheita do café. A coleta de dados foi realizada na Fazenda São João Grande, em Presidente Olegário/MG, em um pivô de 50,0 ha. A cultivar utilizada foi a “Catuaí Vermelho IAC 144”, plantada de forma circular em dezembro de 2000, no espaçamento 4,0 x 0,5 m. Utilizou-se uma grade amostral com 100 pontos georreferenciados em que cada ponto correspondia a 4 plantas. A determinação da força de desprendimento foi realizada por meio de um dinamômetro digital em cada ponto de amostragem. O estádio verde de maturação apresentou força de desprendimento superior ao cereja. Os semivariogramas e a krigagem possibilitaram caracterizar a variabilidade da força de desprendimento entre os frutos estudados. Os mapas de krigagem possibilitam aos agricultores a escolha do melhor local e momento certo para iniciar a colheita mecanizada e seletiva do café e consequentemente, melhoria na qualidade final do produto e nos lucros.Editora UFLA2017-06-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1253Coffee Science - ISSN 1984-3909; Vol. 12 No. 2 (2017); 231-239Coffee Science; Vol. 12 Núm. 2 (2017); 231-239Coffee Science; v. 12 n. 2 (2017); 231-2391984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1253/pdf_1253_2https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1253/1739Copyright (c) 2017 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessFigueiredo, Vanessa CastroFerraz, Gabriel Araújo SilvaSilva, Fabio Moreira daConceição, Fagner Goes daCarvalho, Luis Carlos Cirilo2017-06-06T13:30:36Zoai:coffeescience.ufla.br:article/1253Revistahttps://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:2024-05-21T19:54:00.841658Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
