Estudo da composição mineral de três gramíneas do gênero cynodon. Ciência Animal Brasileira, Goiânia, v. 1, n. 1, p. 31-41, jan./jun. 2000. Disponível em: <https://www.revistas.ufg.br/vet/article/view/240/210>.e- 1809-6891http://repositorio.bc.ufg.br/handle/ri/12387The present work was conducted under field conditions at the Department of Animal Science of the Federal University of Lavras (UFLA), MG, with the objective of evaluating the mineral composition (Ca, P, Mg, K and S) of the grasses Coastcross [Cynodon dactylon (L.) Pers x Cynodon nlemfuensis Vanderyst], Tifton 68 (Cynodon spp) and Tifton 85 (Cynodon spp), submitted to four nitrogen doses (0, 100, 200 and 400 kg/ha), as ammonium sulphate.The soil in the experimental area was a distrophic dark red latosol. In starting the experiment, this soilwas corrected and a basic fertilization was applied (with N, P and K).The experimental design utilized was that of randomized blocks with six replications and the treatments were arranged in a split plot scheme, where the plots were made up of the grasses and the subplots of nitrogen doses. Mineral contents averaged within intervals capable of minimizing or eliminating the need for mineral suplementation of dairy cows.porAcesso AbertoCaCynodonKMgNitrogênioPSNitrogenArtigo
