Resumo: The aim of this study was to measure the amount and distribution of sugar-cane roots, variety RB 785148, under vinasse treatments in a clayey Oxisol in Londrina – Paraná. The profile wall method was used. Roots were counted by analysis of digital images. Vinasse doses were: 0, 150, 300, 450 and 600 m3ha-1. A larger amount of roots was observed closer to the clump in all treatments. All vinasse treatments increased root amount, and 0 – 0.25 m layer presented more roots. An increase in total root amount was observed with increase of vinasse treatment, as a result of an effect on 0-0.25 m layer. Treatments 300 e 450 m3 ha-1 presented sugar cane yield significantly higher than control. Treatment 300 m3 ha-1 was considered economic interesting and had more roots on the 0.25 – 0.50 m soil layer.

Para avaliação das raízes, utilizou-se o método do perfil, sendo estas analisadas através de imagens digitais. Independentemente da dose, a aplicação de vinhaça aumentou a quantidade total raízes, sendo maior o enraizamento na camada de 0 a 0,25 m. Quanto à produtividade de colmos, as doses de 300 e 450 m3 ha-1 proporcionaram produtividades significativamente maiores que a testemunha (0 m3 ha-1). Além de mais econômica, a dose de 300 m3 ha-1 resultou em maior enraizamento na camada de 0,25 a 0,50 m de profundidade.UEL2009-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/209310.5433/1679-0359.2002v23n2p179Semina: Ciências Agrárias; Vol. 23 No. 2 (2002); 179-184Semina: Ciências Agrárias; v. 23 n. 2 (2002); 179-1841679-03591676-546Xreponame:Semina.
