Resumo: | The use of inoculation with Azospirillum brasilense can make forage systems more efficient, reducing the dependence on nitrogen fertilizer. Most of the Azospirillum-plant association studies have been conducted on cereals and annual grasses, especially. More studies with perennial pastures such as bermudagrass (Cynodon dactylon (L.) Pers.) that require a lot of fertilization to show their production potential are needed. In this sense, the production, nutritional value of forages and the response of pasture and animals in were evaluated based on Tifton 85 bermudagrass in association with ryegrass (Lolium multiflorum Lam.), cv. BRS Ponteio, inoculated with A. brasilense and fertilized with doses of nitrogen fertilizer, grazed by lactating cows. Three forage systems were evaluated: (i) Tifton 85 + A. brasilense + 170 kg N ha-¹ year-¹; (ii) Tifton 85 + 190 kg N ha-¹ year-¹ and (iii) Tifton 85 + 240 kg N ha-¹ year-¹.The experimental design was completely randomized, with three treatments (forage systems), three replications (paddocks) and repeated measures in time (averages of grazing cycles per season). Forage samples were collected before and after grazing to assess plant and animal responses. The inoculation of A. brasilense in pasture, based on Tifton 85 bermudagrass, mixed with ryegrass (in winter and spring), demonstrates a positive effect when equivalent to pasture fertilized with 190 kg of N ha-¹, in the response of plants and animals. Forage yields were 28.6; 29.1 and 32.4 t MS ha-¹, respectively. The results demonstrate that the use of inoculation contributes to improve forage systems and reduce the use of nitrogen fertilizers. |

A maioria dos estudos sobre associação de plantas com Azospirillum tem sido realizada em cereais e gramíneas anuais. Mais estudos são necessários com culturas perenes como o capim bermuda (Cynodon dactylon (L.) Pers.) que demandam elevadas doses de adubo nitrogenado para demonstrar seu potencial de produção. Nesse sentido, avaliou-se a produção, valor nutritivo das forragens e a resposta dos animais em pastagens tendo como base o capim Tifton 85 em associação com azevém (Lolium multiflorum Lam.), cv. BRS Ponteio, inoculadas com A. brasilense e fertilizadas com doses de adubo nitrogenado, pastejadas por vacas em lactação. Foram avaliados três sistemas forrageiros: (i) Tifton 85 + A. brasilense + 170 kg N ha-¹ ano-¹, (ii) Tifton 85 + 190 kg N ha-¹ ano-¹ e (iii) Tifton 85 + 240 kg N ha-¹ ano-¹. O delineamento experimental foi o inteiramente casualizado, com três tratamentos (sistemas forrageiros), três repetições (piquetes) e medidas repetidas no tempo (médias dos pastejos por estação do ano). Foram coletadas amostras de forragem ao pré e pós-pastejo para avaliar as respostas das plantas e dos animais. A inoculação de A. brasilense em pastagem, tendo como base o capim Tifton 85, em mistura com azevém, (no inverno e primavera), demonstra efeito positivo ao equivaler-se a pastagem adubada com 190 kg de N ha-¹ ano-¹, na resposta das plantas e dos animais. As produções de forragem foram de 28,6; 29,1 and 32,4 t MS ha-¹, respectivamente. Os resultados demonstram que o uso da inoculação contribui para melhorar os sistemas forrageiros e reduzir o uso de fertilizantes nitrogenados.Universidade Federal de Santa MariaBrasilZootecniaUFSMPrograma de Pós-Graduação em ZootecniaCentro de Ciências RuraisOlivo, Clair Jorgehttp://lattes.cnpq.br/7352405107578701Meinerz, Gilmar RobertoQuatrin, Mauricio PaseCharão, Alisson André de Mello2022-06-15T17:47:11Z2022-06-15T17:47:11Z2022-04-29info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/24880ark:/26339/001300000v727porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2024-07-09T15:10:11Zoai:repositorio.ufsm.br:1/24880Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2024-07-09T15:10:11Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
