Resumo: | Nitrogen is one of the most important nutrients for increasing the yield and quality of forages. This study aimed to evaluate the effect of the different forms of application, spread on the total area using urea fertilizer and foliar using liquid urea, aiming at evaluating the yield and qualitative traits of Panicum maximum cv. Mombaça, at different times of the year. The experimental design was completely randomized blocks in subdivided plots, with three blocks, four treatments, and three collections. The treatments were applied in March 2015 and consisted of the following treatments: 1-control; 2-urea; 3-liquid urea; 4-urea + liquid urea; 5-urea + micronutrients; 6-urea + N liquid; 7-urea + N liquid + micronutrients; 8-control. Samples were collected in May, October, and December 2015. Crude protein (CP) dry matter (DM), mineral matter (MM), and acid detergent fiber (ADF) were evaluated. Results revealed that nitrogen was determinant in improving the yield and forage quality. Treatments with urea spread on total area resulted in increased dry matter production. For the crude protein, the source and the application form are not decisive. Collection time with higher rainfall positively affected the dry matter production, crude protein, and ADF, while urea spread on total area showed the best cost-benefit due to the good results of yield and quality. |

Este trabalho teve como objetivo avaliar o efeito das diferentes formas de aplicações, sendo elas à lanço (utilizando ureia fertilizante) e foliar (utilizando ureia líquida), a fim de avaliar as características produtivas e qualitativas da forrageira Panicum maximum cv. Mombaça, em diferentes épocas do ano. O delineamento experimental foi o de blocos inteiramente casualizados em parcelas subdivididas, com oito tratamentos e três coletas. Os tratamentos foram aplicados em março de 2015 e eram constituídos pelo tratamento 1: controle, tratamento 2: ureia, tratamento 3: ureia líquida, 4: ureia + ureia líquida; 5-ureia + micronutrientes; 6-ureia + N líquido; 7- ureia + N líquido + micronutrients; 8-controle. Foram realizadas coletas em maio/2015, outubro/2015 e dezembro/2015. Foram avaliadas proteína bruta (PB), massa de matéria seca (MMS), matéria mineral (MM) e fibra em detergente ácido (FDA). Os resultados revelaram que o nitrogênio foi determinante na melhora da produtividade e qualidade da forrageira. Os tratamentos com ureia aplicada a lanço resultaram na maior produção de massa de matéria seca. Para a proteína bruta, a fonte e o formato de aplicação não foram decisivos. A época de coleta com maior pluviosidade afetou positivamente a produção de massa de matéria seca, proteína bruta e o FDA da forrageira; e a ureia aplicada a lanço apresentou o melhor custo-benefício atrelado aos bons resultados de produtividade e qualidade.EDUFU2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3971410.14393/BJ-v36n1a2020-39714Bioscience Journal ; Vol. 36 No. 1 (2020): Jan./Feb.; 23-29Bioscience Journal ; v. 36 n. 1 (2020): Jan./Feb.; 23-291981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/39714/27505Brazil; Contemporary Copyright (c) 2020 Marilize Bittencourtt Caldas, Jéssica Pereira Diniz, Andrisley Joaquim da Silva, Simone Pereira da Silva Baio, Monica Cristina Rezende Zuffo Borges, Kenio Batista Nogueira, Cassiano Garcia Roque, Paulo Eduardo Teodorohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCaldas, Marilize BittencourttDiniz, Jéssica PereiraSilva, Andrisley Joaquim da Baio, Simone Pereira da Silva Borges, Monica Cristina Rezende ZuffoNogueira, Kenio BatistaRoque, Cassiano GarciaTeodoro, Paulo Eduardo2022-01-14T20:10:50Zoai:ojs.www.seer.ufu.br:article/39714Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-14T20:10:50Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
