Conteúdo: | The objective of this study was to evaluate different soil management systems, with emphasis in the no-tillage system and its interaction with crop rotation and chemical and physical soil features, as well as on yield of corn, soybean and wheat. The trial was installed in a Haplorthox (Latossolo Vermelho distroférico) in Londrina, Paraná State, Brazil. The experimental layout was a factorial in a randomized block design with four replications. The treatments were as follow: 1) cultivation (field cultivation), 2) no-tillage for three years, 3) continuous no-tillage, 4) disc plow, 5) mouldboard plow, 6) heavy-disc harrow, and 7) plowing yearly. In the treatments 1 and 2, the field cultivator was used for winter crop and it was sown without plain harrow. The rotation systems were: 1) single soybean/wheat rotation and 2) corn/lupin - oat/soybean - wheat(2)/soybean(2). Besides improving soybean yield, the multiple crop rotation reduced the soil resistance and bulk density. After system stabilization, no-tillage provided higher yield to soybean, regardless to the rotation crop system used. Corn performance was less affected by soil management than rotation crop. Corn plants always yielded more when sowed after lupins than fodder radish. Wheat grown in the single crop rotation with soybean yielded less in the no-tillage system. In the other hand, the use of multiple crop rotation improved the performance of wheat.
