Abstract

The aim of this study was to measure the amount and distribution of sugar-cane roots, variety RB 785148, under vinasse treatments in a clayey Oxisol in Londrina – Paraná. The profile wall method was used. Roots were counted by analysis of digital images. Vinasse doses were: 0, 150, 300, 450 and 600 m3ha-1. A larger amount of roots was observed closer to the clump in all treatments. All vinasse treatments increased root amount, and 0 – 0.25 m layer presented more roots. An increase in total root amount was observed with increase of vinasse treatment, as a result of an effect on 0-0.25 m layer. Treatments 300 e 450 m3 ha-1 presented sugar cane yield significantly higher than control. Treatment 300 m3 ha-1 was considered economic interesting and had more roots on the 0.25 – 0.50 m soil layer.
