Abstract

Was evaluated the use of residue of alembic, organic and chemical fertilization on yields and agricultural theoretical spirit in the first ratoon sugarcane. The experiment was initiated in August of 2003, in the Municipal district of Perdões–MG, in Typic Haplustox. The experimental design was of randomized blocks, with 9 treatments and 4 replications, which were: Limming + phosphate rock + chemical fertilizer; reactive rock phosphate + chemical fertilizer; Limming + chemical fertilizer; Limming + reactive rock phosphate + chemical fertilizer + cattle manure; Limming + reactive rock phosphate + cattle manure; Limming + reactive rock phosphate + chemical fertilizer + chicken manure; Limming + reactive rock phosphate + chicken manure; Limming + reactive rock phosphate chemical fertilizer + cane bagasse; Limming + reactive rock phosphate + cane bagasse. It was applied the fertilizers in the following doses: cattlel manure, 30 t ha-1; chicken manure, 3,5 t ha-1; cane bagasse, 24 t. ha-1; reactive rock phosphate, 400 kg ha-1 and 120 kg ha-1 of K2O and P2O5 all applied between the line of sugarcane. The limestone was applied in the dose of 2,5 t ha-1, at planting. The variety was used SP 79 1011. The cattle manure was the only organic source capable to substitute the chemical fertilizer; the cane bagasse, when used as organic source, it should be complemented with the chemical fertilizer; there it did not effect the organic manuring, associated or not with the chemical fertilizer in the principal characteristics of the cane, first ratton; Limming and phosphate application, didn't influence the cane yield and of theoretical of sugarcane brandy.
