Agricultural enterprises must have a professional business management and competitive operational techniques to face competition. The statistical process control (SPC) technique is one of the tools that improve quality and productivity of the companies. Developed and used in factories, the SPC has a large application potential for farming and stocking. Facing this potential development, the aim of this study was to evaluate the quality control effects on tillage operations using the SPC as an evaluation tool. The quality control for the chisel operation provided a reduction of 38.4% on data average variability and increased desired data to 45.0%. For the harrow operation, provided a reduction of 9.8% of the average diameter, and increased in 75.0% the desired stone diameter rate for the area.
