Abstract: The scarification has been used in soil descompaction and when combined with fertilizer and harrowing has been called triple operation, which together can change the quality and increase the productivity of sugarcane. In this study we evaluated the influence two cropping systems in ratoon, associated with different forms of fertilization on the technological quality and productivity of sugarcane. The design was randomized blocks, with split plots, with four replications. In the main plots we evaluated two treatments: C/HE=with chisel plow; S/HE=without chisel plow. The subplots were tested for fertilization treatments: M=mineral fertilization; T=M+filter cake; H=M+humic extract; M+T+H. We evaluated the technological analysis and the production of sugarcane. It was observed that the use of the chisel during the period of the 2nd and 3rd ratoon did not cause changes in technological variables and sugarcane productivity. The fertilizers used did not provided increases in the number of stems per meter nor the productivity of sugarcane stems. The values obtained for brix degree of syrup, apparent sucrose, broth purity, fiber, reducing sugars and total reducing sugars were above minimum values defined by the standard the cane quality in all the treatments, but did not increase the number of stems and crop productivity.
