Resumo: | Irregular rainfall can restrict crop development, so irrigation of pastures serves as a strategy to intensify grass-fed animal production systems. Due to the direct relationship between the availability of soil water and nutrients, the objective was to evaluate the nutrient content in forages irrigated by a central pivot system. This work was carried out in the experimental area of irrigated agriculture at the State University of Mato Grosso do Sul, in Aquidauana-MS, Brazil. The experiment was setup in a completely randomized design, with five replications, in subdivided plots. The treatments of the plots were irrigated and non-irrigated, and the treatments of the subplots were the forages Urochloa brizantha cv. Xaraes, Pennisetum purpureum cv. Napier, Panicum maximum cv. Mombasa and Urochloa ruziziensis cv. Ruziziensis. Foliar concentrations of the nutrients Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sulfur (S), Boron (B), Copper (Cu), Iron (Fe), Manganese (Mn) and Zinc (Zn) were evaluated. Statistical analyses performed included analysis of variance, Tukey test at p <0.05 and linear correlation matrix at p <0.05 and p <0.01 between nutrients and productivity. Irrigation results in higher levels of the macronutrients P, K and Mg, and Fe and Mn micronutrients in forages. The nutrients that correlated with productivity were P and Fe, which both presented negative correlation. The nutrients correlated better with each other than with forage productivity. |

Devido a relação direta entre a disponibilidade de água no solo e os nutrientes, objetivou-se avaliar os teores dos nutrientes em forrageiras irrigadas por pivô central. O trabalho foi realizado na área experimental de agricultura irrigada da Universidade Estadual de Mato Grosso do Sul, em Aquidauana-MS. Adotou-se o delineamento inteiramente casualizado, com cinco repetições, em parcelas subdivididas. Os tratamentos das parcelas foram, irrigado e não irrigado, e os tratamentos das subparcelas, foram as forrageiras Urochloa brizantha cv. Xaraés, Pennisetum purpureum cv. Napier, Panicum maximum cv. Mombaça e Urochloa ruziziensis cv. Ruziziensis. Foram avaliadas as concentrações foliares dos nutrientes Nitrogênio (N), Fósforo (P), Potássio (K), Cálcio (Ca), Magnésio (Mg), Enxofre (S), Cobre (Cu), Ferro (Fe), Manganês (Mn) e Zinco (Zn). Foi realizada a análise de variância, teste Tukey p<0,05 e matriz de correlação linear p<0,05 e p<0,01 entre os nutrientes e a produtividade. A irrigação propicia maiores teores dos macronutrientes P, K e Mg e dos micronutrientes Fe e Mn nas forrageiras. Os teores de nutrientes que correlacionaram com a produtividade foram o P e o Fe, ambos apresentaram correlação negativa. Os teores de nutrientes correlacionaram melhor entre si do que com a produtividade das forrageiras.EDUFU2019-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3948710.14393/BJ-v35n3a2019-39487Bioscience Journal ; Vol. 35 No. 3 (2019): May/June; 679-690Bioscience Journal ; v. 35 n. 3 (2019): May/June; 679-6901981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39487/26102Brazil; ContemporaryCopyright (c) 2019 Carla Deisiane de Oliveira Costa, Adriano da Silva Lopes, Marcos Jefferson Kraeski, Adriano de França, Alisson Rodrigo Almeida Margatto, Eder Duarte Fanaya Júniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessde Oliveira Costa, Carla Deisianeda Silva Lopes, AdrianoKraeski, Marcos Jeffersonde França, AdrianoAlmeida Margatto, Alisson RodrigoDuarte Fanaya Júnior, Eder2022-01-31T23:25:38Zoai:ojs.www.seer.ufu.br:article/39487Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-31T23:25:38Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
