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.展开更多
