The present work sought to characterize the cyanogenic glycoside dhurrin in five sugarcane varieties and to determine its possible relationship with the formation of ethyl carbamate in cachaca. For each variety, methanol, ethyl acetate and hexane extracts were prepared and submitted to thin layer chromatography. Chromatographic spots were revealed with iodine vapors. The physical and chemical parameters of the spirits produced from the five different varieties of sugar cane and by different production processes were within the legal limits. Although not exceeding the limit for ethyl carbamate, a significant variation in the final concentration of this compound was observed for each sample analyzed. The Rf values for the dhurrin standard and for the sugarcane variety SP 83-2847 were equal, similar to those for SP 80-3280 and CTC 11 and different from the Rf values for the RB 86-7515 and IAC 86-2480 samples.

We evaluated several organic fertilizers associated or not to mineral fertilizers, in the cane yield and theoretical sugarcane brandy in plant cane. The experimental design was randomized blocks, with nine treatments and four replications, constituted of： TI： Liming （ 1 ）＋ reactive rock phosphate （2）＋ chemical fertilizer （3）; T2：2 ＋ 3; T3：1 ＋ 3 （control）; T4：1 ＋ 2 ＋ 3 ＋ cattle manure （4）; T5： 1 ＋ 2 ＋ 4; T6：1 ＋ 2 ＋ 3 ＋ chicken manure （5）; T7：1 ＋ 2 ＋ 5; T8：1 ＋ 2 ＋ 3 ＋ cane bagasse （6）; T9：1 ＋ 2 ＋ 6. It was applied the fertilizers in the following doses： cattle manure, 30 t hal; chicken manure, 3.5 t hal; cane bagasse, 24 t ha-1; reactive rock phosphate, 400 kg ha-1 and 120 kg ha-1 of K20 and P205, in the planting furrow. The limestone was distributed in the dose of 2.5 t ha-1 The variety was used SP 79-1011. The cattle manure substituted the chemical fertilization of plant cane. The cane bagasse, when used as organic source should always be complemented with the chemical fertilization; there were no effect of treatments in the principal technological characteristics of the cane.
