The soil preparation, characterized by intense lossening soil and low straw remaining in the soil surface, it is usually used for the cultivation of cassava and has worried producers, technicians, agronomists and researchers because of the environmental problems associated with this kind of preparation. Thus, this study aimed to evaluate the physical properties of soil proportionate by different tillage systems as well as the performance of a planter of cassava. The experiment was conducted in the municipality of Maripa - PR, in Latosol eutroferrico red. It was used the randomized blocks design with split plot disposition, where the main plots went consist of five tillage systems (tillage system with offset disk harrow, disk plow and chisel plow, conservation tillage with chisel plow in April and no-tillage) and two subplots (fallow and consortium of forage turnip+oats). It was evaluated the cone index, the soil moisture, porosity of air and water, total porosity, soil bulk density, the depth of the seed cuttings of cassava and, the population of plants. The soil tillage with disc plow and chisel plow provided better physical conditions in comparison to the no tillage system. The depth of deposition of the seed cuttings of cassava was lower in no-tillage system and in the coverage with forage turnip+oats. The plants population was not influenced by soil tillage systems and coverages.
