The purpose of this research was to study the effect of soil tillage systems in a distrophic Red Latosol on agronomic characteristics of cassava during four growth cycles (1999/2000, 2000/2001, 2001/2002 and 2002/2003), in Araruna, northwest region of Paraná state, Brazil. The experimental design was in completely randomized blocks with eight replications. The treatments consisted of three soil tillage systems: no-tillage, minimum tillage using chiseling and conventional tillage (moldboard plow and disking). The conventional tillage system resulted in taller plants and higher storage roots yield in relation to the minimum and no-tillage system. The root dry matter content was not influenced by the tillage systems used.
