The cassava has great ability to adapt and better develop in deep soils without compaction and aeration well. To achieve these characteristics, this work was carried out by subjecting the culture to eight formats furrows and three separate roofs of soil under the tillage system. The work was conducted in a farm located in the district of Pearl Independent municipality of Maripa - Parana - Brazil, which has Latosol red eutrophic. The experiment went installed in randomized blocks with split plot, in the plots main the different furrow in the subplots the coverages. Effectuate up assessments of moisture, penetrometro of impact, breakup of soil in the furrow, depth of maniva and groove, population of plants, stalks per plant and percentage of plants fallings. The coverages of forage turnip and oats had higher humidity and lower resistance to penetration in the layer of up to 8.75 cm. For sulcadores are obtained different breakup of soil, influencing the depth of furrow and maniva. The coverage of oats presented grooves and manivas most deeper, lower breakup soil, providing conditions for less plants fallings.
