Características do pasto de capim-tanzânia adubado com nitrogênio no final do verão

Abstract: Resumo -O objetivo deste trabalho foi avaliar a massa de forragem, os componentes morfológicos e o valor nutritivo de Panicum maximum cultivar Tanzânia, com aplicação de uma segunda dose de adubação nitrogenada em março, no final do verão. Anualmente, foram aplicados em cobertura 50, 17,5 e 33,2 kg ha -1 de N, P e K, respectivamente, em novembro. Além disso, a metade da área recebeu 50 kg ha -1 de N adicional, em março. Os tratamentos foram doses de 50 e 100 kg ha -1 de N em pastos de capim-tanzânia. Os piquet… Show more

“…Souza et al (2006), evaluating aspects related to the nutritional value of Panicum maximum cultivars, observed a significant effect of nitrogen fertilization on the concentration of crude protein in animal feed, with a positive linear response corresponding to increased nitrogen levels. Euclides et al (2007) evaluated the grass sward characteristics of Tanzania fertilized with nitrogen in late summer and found no significant effect of nitrogen fertilization on the concentration of crude protein in the dry matter forage. They justified this response as a function of the applied nitrogen (50 kg ha -1 ) being low, as any effect of nitrogen on the nutritive value of the plant would be diluted when the results were grouped by wet and dry periods.…”

“…These pastures are subject to seasonal variations, with maximum yield occurring in the rainy season and a significant decline in production during the dry season. (Euclides et al, 2007;Teixeira et al, 2011).…”

“…Consequentemente, a lucratividade do empreendimento pecuário, baseado na exploração de pastagens adubadas adequadamente, poderia ser incrementada de maneira sustentável. Além disso, estudos desse tipo poderiam fornecer estrutura para o desenvolvimento de modelos simples de apoio à tomada de decisão, permitindo ao pecuarista escolher a estratégia de manejo da pastagem e de adubação mais apropriada para a sua situação (euClides et al, 2007).…”
