This study aimed to assess the operational quality of mechanized planting and semi-mechanized sugarcane for RB835054 and SP813250 varieties. The sugarcane has significant importance in Brazil, as it is a strong presence of culture in the economic field, with sugar and ethanol production. The mechanization of agricultural operations has been implemented in order to increase operational performance and reduce cost, thus presenting some possible advantages as the semi-mechanized plantation system. The experimental design was a completely randomized design. There were qualitative differences as regards the number of gems, damage to gems, parallelism and failure of deposition seedlings. The planting system, semi mechanized has better indices for the variables: total gems, viable gems and failures. For furrow depth, the values are similar between the two systems. Mechanized planting system showed better quality for variable row spacing. Among the varieties, there were similar values for almost all variables, but for failures in the deposition of seedlings, SP813250 variety obtained unsatisfactory results as compared to RB835054 in mechanized planting system.
Key words: Mechanization, quality control, Saccharum officinarum, varietal efficiency.
