| Abstract | From the hypothesis that the source and the dose of nitrogen fertilization influence the accumulation of nitrogen in the irrigated sugarcane, this study aimed to evaluate the nitrogen accumulation of different doses of ammonium nitrate and urea by sugarcane irrigated in the cane-plant cycle, using N isotopic dilution technic, in a clayey dystrophic Red Latosol, Cerrado phase. The experiment was conducted at the Raízen Mill, located in the municipality of Jataí-GO, Brazil. Was used the variety IACSP95-5000 in a randomized block design, analyzed in a 4 x 2 factorial, with three replicates. Treatments were four doses of N (30, 60, 120 and 180 kg ha); Two fertilizer sources marked with N isotope (urea and ammonium nitrate). Fertilizers labeled with N isotope were applied in a 1.0 m microparticle within the plots, containing 6.0 rows of 5.0 m, whose useful area were the two central lines. The irrigation was by sprinkling, performed by a central pivot. Was evaluated the variable nitrogen accumulated by sugarcane, em kg ha. The results were submitted to analysis of variance by the F test (p <0.05), regression analysis for N doses and Tukey test comparison (p <0.05) for N sources. Ammonia provided a nitrogen accumulation in the aerial part of sugarcane 15.18% higher than urea. |
