Resumo: The objective of this work was to evaluate the least limiting water range of an Oxisol under a sugarcane cultivation with mechanical and manual  harvesting, and to establish the spatial variability relationship between this attribute and crop productivity. The work was conducted in two areas cultivated with sugarcane, one of which was mechanically harvested without burning since 1996, and the other was manually harvested after burning since 1973. The least limiting water range was evaluated by determining the soil resistance to penetration at 0.002, 0.006, 0.01, 0.03, 0.05, 0.1, 0.5 and 1.5 MPa soil‑water potentials. The least limiting water range varied with soil management changes in both studied systems, which indicates a greater soil degradation and lower water content in the area under manual harvesting. The greater crop yield concentrates in regions of higher least limiting water range.

O trabalho foi desenvolvido em duas áreas cultivadas com cana‑de‑açúcar, uma colhida mecanicamente sem queima desde 1996, e outra colhida com corte manual e queima desde 1973. O intervalo hídrico ótimo foi avaliado pela mensuração da resistência do solo à penetração e pela determinação da água no solo a 0,002, 0,006, 0,01, 0,03, 0,05, 0,1, 0,5 e 1,5 MPa. O intervalo hídrico ótimo variou com as alterações ocorridas no solo, nos dois sistemas de manejo estudados, o que indica maior degradação estrutural do solo e menor conteúdo de água disponível na área com colheita manual. A maior produtividade da cultura se concentra nas regiões de maior intervalo hídrico ótimo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFAPESPAraújo, Fernando SilvaSouza, Zigomar Menezes deSouza, Gustavo Soares deMatsura, Edson EijiBarbosa, Ronny Sobreira2013-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14740Pesquisa Agropecuaria Brasileira; v.48, n.6, jun. 2013; 651-660Pesquisa Agropecuária Brasileira; v.48, n.6, jun. 2013; 651-6601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14740/12157https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/14740/9838info:eu-repo/semantics/openAccess2013-09-05T19:39:28Zoai:ojs.seer.sct.embrapa.br:article/14740Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-09-05T19:39:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
