Resumo: | In some leguminous plants, associations with nitrogen-fixing microorganisms allow their nutrition with nitrogen (N) from the atmosphere. This process is known as Biological Nitrogen Fixation (BNF), where through nitrogenase enzymes, N2 is converted to an available form. This process can replace in part, or in total, nitrogen fertilizers. Cowpea bean is a legume species that is recognized for its high capacity to carry out BNF. In the last decades, studies have encouraged small farmers from north and northeast Brazil to use inoculants with rhizobia species since the results of researches have demonstrated that inoculation is an interesting strategy to improve cowpea production. Considering the specific function of molybdenum (Mo) in the N assimilation, different doses of Mo were tested in this study in order to find doses that could improve and enhance BNF. Therefore, this study aimed to compare nitrogen fertilization and BNF in the N assimilation by plants with different Mo doses. Inoculation was performed with the strains UFLA 03-84 and INPA 03-11B. Doses of Mo were applied in seeds and each pot contained five seeds. Thirty-five days after germination, the plants were analyzed for shoot dry matter and fresh matter, N contents and accumulation, as well as the Soil-Plant Analysis Development (SPAD) Index and nodulation in inoculated plants. The different doses of Mo and also the nodulation treatments did not show significant differences in the contents of N. Plants with N fertilization had significant higher shoot dry matter and root dry matter production, in addition to higher N foliar contents and N accumulation. Therefore, BNF was not as efficient as nitrogen fertilization in the evaluated experimental conditions using cowpea beans. |

Este processo é conhecido como Fixação Biológica de Nitrogênio (FBN), onde através de enzimas nitrogenase N2 é convertido na forma disponível. Este processo pode substituir em parte, ou no total, fertilizantes nitrogenados. O feijão-caupi é uma espécie de leguminosa que é reconhecida pela sua alta capacidade de FBN. Nas últimas décadas, estudos encorajaram os pequenos agricultores do norte e nordeste do Brasil a usar inoculantes com espécies de rizobio, uma vez que os resultados das pesquisas têm demonstrado que a inoculação é uma estratégia interessante para melhorar a produção dessa cultura. Considerando a função específica do molibdênio (Mo) na assimilação do N, diferentes doses de Mo foram testadas neste estudo, a fim de encontrar doses que possam melhorar e potencializar a FBN. A inoculação foi feita com as estirpes UFLA 03-84 e INPA 03-11B. As diferentes doses de Mo foram aplicadas na semente, cinco sementes por vaso. Trinta e cinco dias após a germinação, as plantas foram analisadas com relação à matéria seca aérea e radicular, teor de N e acúmulo, índice de análise de desenvolvimento solo-planta (SPAD) e nodulação nas plantas inoculadas. As diferentes doses de Mo não mostraram diferenças significativas no conteúdo de N, nem no processo de nodulação. As plantas com adubação nitrogenada tiveram mattera seca da parte aérea e de raízes superior as inoculadas, além de maiores teores foliares de N. Portanto, para feijão-caupi, a FBN não foi tão eficiente quanto o fertilizante nitrogenado nas condições experimentais avaliadas.EDUFU2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4234310.14393/BJ-v36n1a2020-42343Bioscience Journal ; Vol. 36 No. 1 (2020): Jan./Feb.; 102-112Bioscience Journal ; v. 36 n. 1 (2020): Jan./Feb.; 102-1121981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42343/27514Brazil; Contemporary Copyright (c) 2020 Daniele Cabral Michel, Isabela Cristina Filardi Vasques, Geisislaine do Carmo Reis Araújo, Jordana Luísa de Castro, Lucas Lenin Resende de Assis, Rayner Hugo Cassa Louzada dos Reis, Maria Lígia de Souza Silva, Valdemar Faquimhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMichel, Daniele CabralVasques, Isabela Cristina FilardiAraújo, Geisislaine do Carmo Reisde Castro, Jordana Luísade Assis, Lucas Lenin Resendedos Reis, Rayner Hugo Cassa LouzadaSilva, Maria Lígia de SouzaFaquim, Valdemar2022-01-18T19:37:35Zoai:ojs.www.seer.ufu.br:article/42343Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-18T19:37:35Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
