Resumo: | The objective of this experiment was to evaluate the yield and quality of corn silage with different nitrogen levels. It was used four levels of nitrogen, 0, 80, 160, 240 kg.ha-1. The experimental design was randomized blocks with six replications. The data were subjected to analysis of variance and polynomial regression analysis. The silage was performed manually in PVC tubes of 10 cm diameter and 50 cm high. The parameters evaluated were productive variable, morphological variable, physiological efficiency, recovery efficiency and efficiency utilization of nitrogen, and nutritive value of silages. Plant height (height = 1.72+0.067*block+0.0004*N) and total production (total production = 13,883.42 + 786.41* block + 18.65*N) responded positively according increasing nitrogen dose. The decrease of recovery efficiency (NAR = 1.027-0.00283*N) and nitrogen use efficiency (NUE = 42.89 to 0.11 * N) with the increase in the amount of nitrogen applied. The crude protein of the silage shown a quadratic response (CP = 5.820+0.018*N-0.00005N2) according to the increase in nitrogen level. The increase in nitrogen levels provided better productivity with high quality silage. Higher doses showed lower nitrogen utilization efficiency and recovery nitrogen. |

Foram utilizados quatro níveis diferentes de nitrogênio, sendo: 0; 80; 160; 240 kg ha-1 de nitrogênio. O delineamento experimental utilizado foi o de blocos ao acaso com seis repetições. Os dados foram submetidos à análise de variância e à análise de regressão polinomial. A ensilagem foi realizada manualmente em tubos de PVC de 10 cm de diâmetro e 50 cm de altura. Foram avaliados os parâmetros produtivos, morfológicos, eficiências fisiológicas, de recuperação e de utilização do nitrogênio, além das variáveis bromatológicas das silagens. A altura da planta (Altura = 1,72 + 0,067*bloco + 0,0004*N) e produção total (Produção total = 13883,42+786,41*bloco+18,65*N) responderam positivamente ao incremento da dose de nitrogênio. Na medida em que houve incremento na quantidade de nitrogênio aplicado houve diminuição na eficiência de recuperação (RAN = 1,027 – 0,00283*N) e na eficiência de utilização do nitrogênio (EUN = 42,89 – 0,11*N). A proteína bruta da silagem apresentou resposta quadrática (PB = 5,820+0,018x-0,00005x2) de acordo com o aumento na dose de nitrogênio. O acréscimo nas doses de nitrogênio proporcionou melhor produtividade de silagem com alta qualidade. Maiores doses proporcionaram menor eficiência de utilização e de recuperação do nitrogênio.
