Resumo: The expansion in areas planted with eucalyptus crops has raised concern about the effects these may have on water resources and existing correlations between water use and crop productivity, which calls for better understanding of water requirements by plant species. The objective of this study was to determine the water requirements of an irrigated eucalyptus crop, having the estimated dual crop coefficient (dual Kc) as a reference. Mean values found for estimated crop coefficients were 0.57, 0.13 and 0.70 for Ke, Kcb and Kc respectively during initial growth stage, and 0.01, 0.81 and 0.82 for Ke, Kcb and Kc respectively during the mid-season stage. The methodology used in this study is not intended to replace field measurements for development of Kc curves. However, it provides a consistent method to evaluate values measured while providing means for estimating variations in values of Kc according to change in the soil fraction covered by vegetation.

A proposta deste trabalho foi determinar as necessidades hídricas da cultura do eucalipto irrigado, tendo como referência a estimativa do coeficiente dual de cultura (Kc dual ). Os valores médios para os coeficientes de cultura estimados foram de 0,57; 0,13 e 0,70 para Ke , Kcb e Kc , respectivamente, na fase inicial de crescimento e de 0,01; 0,81 e 0,82 para Ke , Kcb e Kc , respectivamente, na fase média de crescimento da cultura. A metodologia empregada, no presente trabalho, não substitui as medidas em campo para o desenvolvimento das curvas de Kc . Entretanto, fornece uma forma consistente de avaliar os valores medidos, bem como fornecer meios para estimar as alterações nos valores de Kc com a mudança da fração de solo coberta por vegetação.CERNE2016-04-052017-08-01T20:15:06Z2017-08-01T20:15:06Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/898http://repositorio.ufla.br/jspui/handle/1/14498CERNE; Vol 19 No 2 (2013); 247-253CERNE; Vol 19 No 2 (2013); 247-2532317-63420104-7760reponame:Repositório Institucional da UFLAinstname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/898/675Copyright (c) 2016 CERNEhttp://creativecommons.org/licenses/by/4.0/Attribution 4.0 Internationalinfo:eu-repo/semantics/openAccessAlves, Maria Emília BorgesMantovani, Everardo ChartuniSediyama, Gilberto ChohakuNeves, Júlio César Lima2021-04-20T16:50:55Zoai:localhost:1/14498Repositório InstitucionalPUBhttp://repositorio.ufla.br/oai/requestnivaldo@ufla.br || repositorio.biblioteca@ufla.bropendoar:2021-04-20T16:50:55Repositório Institucional da UFLA - Universidade Federal de Lavras (UFLA)false
