MANFRON, Paulo Augusto; LIBARDI, Paulo Leonel; PAULETTO, Eloy Antonio  e  MORAES, Sérgio Oliveira. EFFECT OF SOIL TILLAGE METHODS ON ROOT DISTRIBUTIOM OF CORN (Zea mays, L.) CROP ON AN OXIC PALEUDALF SOIL. Cienc. Rural [online]. 1991, vol.21, n.3, pp.353-366. ISSN 0103-8478.  https://doi.org/10.1590/S0103-84781991000300004.

An experiment was conducted to determine the effect of two soil tillage methods (subsoiling and non-sobsoiling) on root distribution of corn (Zea mays, L.) in several soil profiles. It was located in Piracicaba, SP, Brazil and the samples were 0,008m3 soil monoliths with corn roots, took from pits with dimension of 1,12 X 0,90 X 1,00m. It was observed a greater root mass and a greater variability on root distribution in the subsoiled as compared with the treatment without subsoiling. However no statical diference was observed among treatments.

Palavras-chave : soil tillage; root distribution; corn.
