Resumo: | Mate tea leaves are the product of commercialization of the mate-tea tree (Ilex paraguariensis St. Hil.), which leads to a great export of N, requiring its reposition. In previous nutritional studies of the mate-tea tree, it was observed that its production and metabolism was positively influenced by the ammonium form nitrogen fertilizer. This investigation tested different levels of nitrogen fertilization, in its ammonium form, in a commercial plantation, for verifying its effects on the nutritional status and on the productivity. The experiment was assembled in the region of Ivaí - Paraná, using, as fertilizer, the ammonium sulfate in the dosages of 00, 40, 60, 80 kg N ha-1. The statistical design was randomized blocks, with a split-plot arrangement, consisting of four treatments, two evaluation seasons with five replications and twenty plants per plot, being laid out in a 2,0 m x 3,5 m spacing. The evaluation of the plant’s nutritional status was performed through foliar analysis total N, K, P, Ca, Mg, Fe, Mn, Cu, Zn and Al, in winter and summer, with fertilizations performed for two years. It was concluded that nitrogen supplied in the form of ammonium sulfate has a positive influence on the biomass up to the rate of 52,5 kg N ha-1. The harvesting season influences the plant’s chemical composition. The fertilization significantly influences the foliar contents of N, K and Mg and Zn during winter and Fe, Cu e Al during summer. |

Em estudos nutricionais, observou-se que a produção e o metabolismo da erva-mate são influenciados, beneficamente, pelo adubo nitrogenado. Nesse sentido, testou-se, neste trabalho, diferentes níveis da adubação nitrogenada, em um plantio comercial objetivando avaliar seus efeitos no estado nutricional e na produtividade da planta. O experimento foi instalado em Ivaí Paraná, como adubo utilizou-se o sulfato de amônio nas doses de 0, 40, 60, 80 kg N ha-1. O delineamento estatístico utilizado foi o de blocos ao acaso com parcelas subdivididas, constituídas por quatro tratamentos e duas épocas de avaliação, vinte plantas úteis por parcela e cinco repetições; espaçamento 2,0 m x 3,5 m. As adubações foram realizadas por dois anos. A avaliação do estado nutricional da planta foi através de análise foliar para: N, P, K, Ca, Mg, Fe, Mn, Cu, Zn e Al, em duas diferentes estações (inverno verão). Concluiu-se que o sulfato de amônio, tem influência positiva na biomassa comercial até a dose de 52,5 kg N ha-1 , no inverno. A época de coleta das folhas influencia na composição química da planta, sendo maiores os teores de N, K, Mg e Zn, no inverno e menores os teores de Fe, Cu e Al, no verão.Universidade Federal de Lavras (UFLA)2015-09-112017-08-01T20:15:54Z2017-08-01T20:15:54Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfRIBEIRO, M.
