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