Resumo: | The Tifton 85 grass offers high yield and nutritional value. It is demanding in soil fertility and highly responsive to fertilization. However, the response to fertilization can be affected by the source, dose, and installment of fertilizers, as well as environmental conditions. Evaluations of the joint application of chemical and organic fertilizers are scarce. Therefore, this study aimed to evaluate the effect of chemical and organic fertilization on agronomic characteristics, mineral use efficiencies, and bromatological composition of Tifton 85 grass, and determine fertilization strategies to optimize the yield and nutritional value of Tifton 85 grass. The findings were influenced by grass cuttings. The highest values for height and accumulated dry matter productivity were obtained with the highest fertilizer doses. The leaf/stem ratio was not affected by fertilization. The highest mineral use efficiencies were obtained with 200 and 400 kg of N/ha/year of NPK 20-00-20 formulation and up to 10 t/ha/year of poultry litter (PL), and these values decreased when applying high PL doses. The crude protein content increased, while the contents of neutral detergent fiber and acid detergent fiber decreased. The protein fractions and in vitro dry matter digestibility were not affected by fertilization. The potassium content increased with high fertilizer doses. Applying 350 to 400 kg of N/ha/year of NPK 20-00-20 formulation and 25 to 30 t/ha/year of PL promoted the highest accumulated dry matter productivity. Applying 200 to 400 kg of N/ha/year of NPK 20-00-20 formulation and 10/ha/year of PL is recommended for optimizing mineral use efficiencies. As for bromatological composition, increasing the doses of both fertilizers was beneficial in reducing fiber contents, but only organic fertilization increased crude protein content. |

É exigente em fertilidade do solo e altamente responsivo a fertilização. Entretanto, a resposta a fertilização pode ser afetada pela fonte, dose e parcelamento dos fertilizantes, e pelas condições ambientais. Avaliações da aplicação conjunta de adubos químicos e orgânicos são escassas. Portanto, objetivou-se avaliar o efeito da adubação com NPK 20-00-20 e cama-de-frango nas características agronômicas, eficiência de utilização dos nutrientes minerais e composição bromatológica do capim Tifton-85. Os maiores valores de altura, taxa de acúmulo diário e produtividade de matéria seca foram obtidos nas maiores doses dos fertilizantes. A relação folha/colmo não foi influenciada pelas fertilizações. As eficiências de utilização dos nutrientes minerais reduziram com elevação das doses de cama-de-frango. As maiores eficiências de utilização dos nutrientes minerais foram obtidas nas doses de 200 e 400 kg de N/ha/ano de NPK 20-00-20 e de até 10 t/ha/ano de cama-de-frango. O teor de proteína bruta aumentou, os teores de fibra insolúvel e detergente neutro e fibra insolúvel em detergente ácido reduziram. As frações proteicas e a digestibilidade in vitro da matéria seca não foram afetadas pelas fertilizações. O teor de potásio aumentou com elevação das doses dos fertilizantes. Elevadas doses dos fertilizantes aumentaram a produtividade e melhoram a composição bromatológica do capim Tifton-85. No entanto, os resultados obtidos foram influenciados pelos fatores climáticos.Universidade Federal de Uberlândia2023-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/6373010.14393/BJ-v39n0a2023-63730Bioscience Journal ; Vol. 39 (2023): Continuous Publication; e39063Bioscience Journal ; v. 39 (2023): Continuous Publication; e390631981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/63730/35928Brazil; Contemporary Copyright (c) 2023 Naiara Taís Alves da Silva, Alex de Matos Teixeira, Lúcio Carlos Gonçalves, Daniel Ottoni, Luigi Francis Lima Cavalcanti, Thaís Figueiredo Pereira, Flávia Cristina de Oliveira e Silva, Diogo Gonzaga Jaymehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Silva, Naiara Taís Alves daTeixeira, Alex de MatosGonçalves, Lúcio CarlosOttoni, DanielCavalcanti, Luigi Francis LimaPereira, Thaís FigueiredoOliveira e Silva, Flávia Cristina deJayme, Diogo Gonzaga2024-01-31T19:16:18Zoai:ojs.www.seer.ufu.br:article/63730Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2024-01-31T19:16:18Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
