SUGARCANE BASE CUTTING QUALITY USING RECTANGULAR AND CIRCULAR BLADES

Sugarcane mechanized harvesting can lead to serious risks the longevity of plantations when improperly operated, and may cause damages disturbances in remaining ratoons field. In this sense, study aimed evaluate damage disturbance sugarcane by base cutting quality two-blade models through statistical process control. The experiment was carried out during 2015/16 growing season an agricultural area Moreno Mill, located Cravinhos, São Paulo, Brazil. harvester A8800 (Machine 1) BE1035 2). variety cultivated both treatments SP80-1816. Thirty points were sampled per harvester, with 10-minute intervals between them. Equations used calculate indices, which then evaluated descriptive analysis Machine 2 presented instability for index damages, lower data variability. On other hand, 1 due indicator disturbance, but a operation
