Resumo

In this study, different nitrogen doses (0, 16, 48, 64, 80, and 96 kg ha(-1)) from two sources, biofertilizer (from anaerobic digestion of cattle wastewater) and urea, were applied to cultivate two sugarcane varieties (RB 867515 and SP 803280). A degrees Brix values higher than 21% were obtained with application of 80 kg ha(-1) from biofertilizer. The mean productivity of the cultivar RB 867515 using biofertilizer was 147.5 ton ha(-1), while from urea it was 136.87 ton ha(-1). The cultivar SP 803280 produced an average yield of 152.25 ton ha(-1) when applying biofertilizer and 154.37 ton ha(-1) with use of urea. Significant differences (P ae<currency> 0.05) between the use of biofertilizer and urea were detected for cultivar RB 867515 in terms of crude protein concentration. The application of 80 kg of N ha(-1) was considered the ideal dose, corresponding to fertirrigation blades of 54 mm of biofertilizer. The experiment showed that the biofertilizer formulation analyzed can replace urea as a nitrogen source for growing sugarcane. (AU)
