Resumo
The objective of this study was to evaluate the productivity and technological characteristics of sugarcane,variety RB 86-7515. The experiment was carried out in the experimental area of the School of Agronomy, of the Federal University of Goiás. A completely randomized experimental design(CRD) was applied, with three replicates, in a 5x5x2 factorial scheme. The plants were grown in containers of 200 liters. The treatments were five vinasse doses (0, 165, 330, 495 and 660 m3h-1) and five doses of lithothamnium (0, 100, 200, 300 and 400 kg ha-1) and cultivation under irrigated and unirrigated. The irrigation system used was drip emitters with flow rate of 4 L h-1. The variables evaluated were fiber % cane; Brix % juice; pol % cane; juice purity and total recoverable sugar -TRS and productivity per hectare. The treatments produced significant effects on the parameters of crop growth, and irrigated plants, fertilized with 200 kg ha-1 lithothamnium and 330 m3ha-1 of vinasse showed the best results.
