Resumo: | Nitrogen is an one principal among others, essential and responsible nutrient for forage productivity and pasture quality increasing. Besides that, this paper objective was to evaluate nitrogen doses and source effects on nutrient concentration in marandu palisadegrass. The experiment was carried out from July of 2003 to March of 2006 at the Modelo Farm of University Goiás State in an 882 m2 area.The pasture was established for more than ten years and it was presenting low herbage production being considered in moderate degradation phase. The treatment combination was made in a split-plot design with three replicates. Main plot,arrangements in a randomized complete block design was employed, were turned by a 2 x 4 factorial, being two sources of N (ammonium sulfate and urea) and four doses of N (0, 100, 200 and 300 kg ha-1 yr-1). On each year, during the three years, three cuts evaluating are done at the forage plant. The rates of Nitrogen didn’t come to the maximum point to the concentrates of N, K, Mg, S, Cu and Fe. Increasing N rates promoted reduction in phosphorus absorption in plant tissue. Higher N:S relation were observed in plants which received urea as nitrogen source. The application of nitrogen, affected the nutritional status of signal grass and the recovery of this. The application of nitrogen, affected the nutritional status of signal grass and it recovering. |

Diante disso, objetivou-se avaliar o efeito de doses e fontes de nitrogênio na concentração de nutrientes do capim-marandu. O experimento foi desenvolvido de julho de 2003 a março de 2006, na Fazenda Modelo da Universidade Estadual de Goiás. O delineamento experimental utilizado foi em blocos casualizados com parcelas subdivididas no tempo, com três repetições. Utilizou-se o esquema fatorial 2 x 4, sendo duas fontes de nitrogênio (sulfato de amônio e ureia) e quatro doses de nitrogênio (0, 100, 200 e 300 kg ha-1 ano-1). Em cada um dos anos, procedeu-se a três cortes de avaliação da planta forrageira. As doses de nitrogênio não atingiram o ponto de máximo para as concentrações de N, K, Mg, S, Cu e Fe. O incremento na adubação nitrogenada reduz a absorção de P. O nitrogênio na fonte de ureia promo-ve maior relação N:S. A aplicação de nitrogênio influencia o estado nutricional do capim-marandu e sua recuperação.Universidade Federal de Goiás (UFG), Escola de Veterinária e Zootecnia (EVZ)2020-09-07T22:24:26Z2020-09-07T22:24:26Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCOSTA, K.
