Resumo: GIS techniques have been used in many agricultural crops to study and assess the causes of spatial and temporal variability in production. The spatial and temporal variability of the canephora (conilon) coffee productivity was analyzed in the present work in three consecutive agricultural years (harvests) using geoprocessing techniques. A sampling grid with 109 georeferenced points was built with five plants per point. Significant differences in productivity were observed, with the lowest productivity recorded for the harvest 3 in 93.5% of the area. The productivity index (YI) varied from -18.0% in harvest 2 to harvest 1 and from -57.0% in harvest 2 to harvest 3, showing increasing decrease between different harvests.

Este trabalho foi desenvolvido objetivando-se analisar a variabilidade espacial e temporal da produtividade do cafeeiro canephora (conilon) em três safras consecutivas, utilizando técnicas de geoprocessamento. Uma malha amostral foi construída com 109 pontos georreferenciados, considerando cinco plantas por ponto. As produtividades apresentaram diferenças significativas, com menor produtividade na safra 3, em 93,5% da área. O índice de produtividade (IP) ficou da safra 2 para a 1 em -18,0% e da safra 3 para a 2 em -57,0%, mostrando redução crescente entre as diferentes safras.Editora UFLA2014-07-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/672Coffee Science - ISSN 1984-3909; Vol. 9 No. 3 (2014); 400-407Coffee Science; Vol. 9 Núm. 3 (2014); 400-407Coffee Science; v. 9 n. 3 (2014); 400-4071984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/672/pdf_106https://coffeescience.ufla.br/index.php/Coffeescience/article/view/672/1261Copyright (c) 2014 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessLima, Juliao Soares de SouzaCosta, Felipe PiannaXavier, Alexandre CandidoOliveira, Rone BatistaSilva, Samuel Assis2014-07-21T16:01:06Zoai:coffeescience.ufla.br:article/672Revistahttps://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:2014-07-21T16:01:06Coffee Science (Online) - Universidade Federal de Lavras (UFLA)false
