Resumo: The objective of this study was to evaluate the effect of irrigation and cultivation of brachiaria among coffee trees lines on physical-hydric Oxisol quality at Brazilian central plateau. The experiment was carried out in five randomized blocks in a factorial design 2 x 2, with two water treatments, irrigated and rainfed systems, and two management systems, with and without brachiaria between coffee trees lines. The research strategy was based on studying soil water storage based on porosity distribution due to the behavior of physical parameters in different water and management treatments. Soil samples were collected in duplicate in each plot at depths from 0.0 to 0.05, 0.05 to 0.10, 0.10 and 0.20 m. The irrigation regime increased soil bulk density in the surface layer without reducing its readily available water that, due to presence of brachiaria was increased by 18%. In general, irrigated brachiaria had a positive effect on the physical-hydric soil characteristics of the soil and promoted an increase in readly available soil microporosity from the redistribution of pore diameter characterized by increasing retention curve amplitude in the soil water tension range corresponding to the readily-available water.

O ensaio foi delineado em cinco blocos ao acaso, em esquema fatorial 2 x 2 sendo dois regimes hídricos, irrigado e sequeiro, e dois sistemas de manejo das entrelinhas, com e sem braquiária. A estratégia de pesquisa fundamentou-se na investigação do armazenamento de água do solo com base na distribuição da porosidade, em função do comportamento dos atributos físico-hídricos nos diferentes tratamentos. Foram coletadas amostras de solo em duplicada em cada parcela experimental, nas profundidades de 0,0 a 0,05; 0,05 a 0,10; 0,10 a 0,20 m. O regime de irrigação aumentou a densidade do solo na camada superficial do solo, sem prejudicar sua capacidade de armazenamento de água. Em relação à braquiária houve efeito positivo de suas raízes sobre os atributos físico-hídricos do solo, provendo o incremento da Microporosidade de baixa retenção (Mib), caracterizada pelo aumentando da amplitude na curva de retenção, na faixa de tensão correspondente a água prontamente disponível (APD), que foi acrescida em 18% ao longo do perfil.Editora UFLA2014-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/745Coffee Science - ISSN 1984-3909; Vol. 9 No. 4 (2014); 516 - 526Coffee Science; Vol. 9 Núm. 4 (2014); 516 - 526Coffee Science; v. 9 n. 4 (2014); 516 - 5261984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/745/pdf_134Copyright (c) 2014 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessRocha, Omar CruzGuerra, Antonio FernandoRamos, Maria Lucrécia GerosaOliveira, Alberto da SilvaBartholo, Gabriel Ferreira2014-10-11T18:41:58Zoai:coffeescience.ufla.br:article/745Revistahttps://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:2024-05-21T19:53:49.065737Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
