Resumo: This study aimed to study morphogenic and structural characteristics of Tanzania grass (Panicum maximum cv. Tanzania) intercropped with Estilosantes Campo Grande (Stylosanthes capitata and Stylosanthes macrocephala) or fertilized with nitrogen. The pasture was managed under continuous stocking and variable stocking rate. Were used a randomized complete blocks with split plots and three replications. The treatments were: Tanzania grass + Stylosanthes; Tanzania grass + 75 Kg N.ha. year-1; Tanzania grass + 150Kg N.ha.year-1; Tanzania grass + 225 Kg N.ha.year-1. Were used urea and ammonium nitrate as nitrogen source. The morphogenetic evaluations were conducted in the spring and summer. Were evaluated 15 tillers per paddock, twice a week for four weeks per season in study. The morphogenic characteristics were not affected by nitrogen fertilization or consortium, except the leaf elongation rate (LER). The highest values for this variable were observed in the spring in the fertilized pastures. Therefore, it is concluded that nitrogen fertilization influences the leaf elongation rate (LER) of Tanzania grass, and this one when is intercropped with Stylosanthes Campo Grande show morphogenic characteristics similar when fertilized with nitrogen, except for rate leaf elongation.

Tanzânia) consorciado com Estilosantes Campo Grande (Stylosanthes capitata e Stylosanthes macrocephala) ou adubado com nitrogênio. O pasto foi manejado sob lotação contínua e taxa de lotação variável. Foi utilizado delineamento experimental em blocos ao acaso com parcelas subdivididas, com três repetições. Os tratamentos foram: capim-Tanzânia + Estilosantes; capim-Tanzânia + 75 Kg N.ha.ano-1; capim-Tanzânia + 150 Kg N.ha.ano-1 e capim-Tanzânia + 225 Kg N.ha.ano-1. Foram utilizados ureia e nitrato de amônia como fonte de nitrogênio. As avaliações morfogênicas foram realizadas na primavera e no verão. Foram avaliados 15 perfilhos por piquete, duas vezes por semana, durante quatro semanas por estação em estudo. As características morfogênicas, exceto a taxa de alongamento foliar (TAlF), não foram influenciadas pela adubação nitrogenada ou consórcio com Estilosantes. Os maiores valores para esta variável foram observados na primavera, nas pastagens adubadas. Desta forma, conclui-se que a adubação nitrogenada influencia a taxa de alongamento foliar (TAlF) do capim-Tanzânia, e este quando é cultivado em consórcio com o Estilosantes Campo Grande apresenta características morfogênicas semelhantes quando adubado com nitrogênio, à excessão da taxa de alongamento foliar.UEL2015-08-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa realizada em Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1661310.5433/1679-0359.2015v36n4p2739Semina: Ciências Agrárias; Vol. 36 No. 4 (2015); 2739-2752Semina: Ciências Agrárias; v. 36 n. 4 (2015); 2739-27521679-03591676-546Xreponame:Semina.
