Resumo: | Abstract The aim of this study was to evaluate the effect of different doses of organic fertilization with doses of lithothanmium and vinasse on the initial growth of sugarcane cv. RB 86-7515. The study was carried out in the experimental area of the School of Agronomy, of Universidade Federal de Goiás, Brazil. A completely randomized experimental design was carried out to analyze data with three replicates, in a 5 x 5 x 2 factorial scheme. Plants were cultivated in containers of 200 liters. Treatments correspond to five vinasse doses (0, 165, 330, 495 and 660 m3.h-1) and five doses of lithothanmium (0, 100, 200, 300 and 400 kg.ha-1) and sugarcane cultivation under irrigated and rainfed conditions. Irrigation was carried out using a drip emitter system with a flow rate of 4 L.h-1. Application of fertilizer treatments were parceled out according to nutrient uptake progress from sugarcane plants. Variables evaluated were as follows: number of buds, plant height, leaf area index and stem diameter, over different growing stages. Treatments produced significant effects on crop growth parameters; results showed that irrigated and fertilized sugarcane plants with 196 kg.ha-1 of lithothanmium and 165 m3.ha-1 of vinasse exhibited the best results.
