Resumo: | This study aimed to assess the impact of tillage systems on physical properties of an Alfissol type soil and on the growth of sweet potato tuberous roots. To assess the soil physical properties, an experiment was conducted in randomized blocks design, in split-plot scheme. The plots consisted of the treatments conventional tillage with making mounds and straw incorporated, conventional tillage with making mounds and without straw, reduced tillage with straw on the soil surface and reduced tillage without straw; and the subplots, to collect periods. The soil physical properties evaluated were soil bulk density, total soil porosity, soil macroporosity and soil microporosity, soil resistance to penetration and gravimetric soil water. For the assessment of the growth of sweet potato tuberous roots, it was adopted an experiment where the plots corresponded to the soil management forms and subplots to four collect periods: 90, 120, 150 and 180 (DAP). The length / roots diameter of individual roots relations were avaluated. It was concluded that the reduced tillage gives greater soil resistance to penetration of roots, by reducing the vertical growth of roots, and the presence of straw incorporated in the conventional tillage favors maintenance of lowest soil bulk density and highest soil macroporosity along the time. |

Para avaliação das propriedades físicas foi instalado experimento em blocos ao acaso, esquema de parcelas subdivididas. As parcelas corresponderam aos tratamentos preparo convencional com confecção de leiras e palha incorporada, preparo convencional com confecção de leiras sem palha, preparo reduzido com manutenção de palha na superfície e preparo reduzido sem manutenção de palha; e as subparcelas, a épocas de avaliação. Foram avaliadas densidade, porosidade total, macro e microporosidade, resistência à penetração de raízes e umidade gravimétrica do solo. Para avaliação do crescimento de raízes tuberosas foi instalado experimento no qual as parcelas corresponderam às formas de manejo do solo e as subparcelas, a épocas de colheita: 90, 120, 150 e 180 DAP. Foram avaliadas as relações comprimento/diâmetro de raízes tuberosas. Concluiu-se que o preparo reduzido confere maior resistência à penetração, reduzindo o crescimento das raízes tuberosas em comprimento, e que a presença de palha incorporada no preparo convencional favorece manutenção de menor valor de densidade de solo e maior macroporosidade ao longo do tempo.UEL2014-02-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1462510.5433/1679-0359.2014v35n1p227Semina: Ciências Agrárias; Vol. 35 No. 1 (2014); 227-238Semina: Ciências Agrárias; v. 35 n. 1 (2014); 227-2381679-03591676-546Xreponame:Semina.
