The objective of this paper was to evaluate the economic profitability of cassava crop submitted to the three soil tillage systems during the years 1999/2000 to 2002/2003, in Araruna, state of Parana. The treatments consisted of three soil tillage systems: no-tillage, minimum tillage using chiseling, and conventional tillage with moldboard plow and disking, arranged in a randomized complete blocks with eight replications. The traction strength and fuel consumption in the soil tillage and in the cassava sowed operation were more required in the conventional tillage system. The conventional and the minimum tillage systems showed the highest costs for fuel, soil tillage and cassava sowed. They also presented the highest gross income. The greatest net income and the best benefit/cost relation were observed in the conventional tillage system, which showed the highest storage root yield compared to the minimum and to the no-tillage systems.Downloads
