Resumo: | The objective of this work was to evaluate the agronomic performance of corn (Zea mays) grown single and intercropped with Urochloa ruziziensis in succession to soybean (Glycine max) inoculated with Bradyrhizobium japonicum, as well as the inoculation and reinoculation of corn with Azospirillum brasilense, in two contrasting soils. The experiment was carried out in two crop years, in a randomized complete block design, in a 2x2x3 factorial arrangement, with five replicates. The first evalauted factor was composed of the two constrasting soils: a clayey Rhodic Eutrustox and a sandy Rhodic Haplustox. The second factor was corn cultivation: single and intercropped with U. ruziziensis. The third factor consisted of the inoculation onto soybean and corn in succession, as follows: no inoculation in both crops, inoculation with B. japonicum onto soybean and with A. brasilense onto corn, and reinoculation with B. japonicum + A. brasilense onto soybean and with A. brasilense onto corn. In both crop years, the highest corn yields are observed in clayey soil with seeds reinoculated with A. brasilense. The annual reinoculation with A. brasilense results in a higher corn grain yield in the intercropping with U. ruziziensis in the clayey soil. Inoculation and reinoculation reduce corn yield losses caused by the competition with U. ruziziensis in intercropping. |

O experimento foi realizado em duas safras, em delineamento de blocos ao acaso, em arranjo fatorial 2x2x3, com cinco repetições. O primeiro fator avaliado foi composto pelos dois solos contrastantes: Latossolo Vermelho eutrófico argiloso e Latossolo Vermelho distrófico arenoso. O segundo fator foi o cultivo de milho: solteiro e consorciado com U. ruziziensis. Já o terceiro fator consistiu na inoculação em soja e milho em sucessão, como a seguir: sem inoculação nos dois cultivos, inoculação com Bradyrhizobium japonicum em soja e com A. brasilense em milho, e reinoculação com B. japonicum + A. brasilense em soja e com A. brasilense em milho. Nos dois anos de cultivo, as maiores produtividades de milho são observadas no solo argiloso com sementes reinoculadas com A. brasilense. A reinoculação anual com A. brasilense resulta em maior produtividade de grãos de milho no consórcio com U. ruziziensis no solo argiloso. A inoculação e a reinoculação reduzem as perdas de produtividade do milho causadas pela competição com U. ruziziensis no consórcio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraConselho Nacional de Desenvolvimento Científico e TecnológicoEmbrapa Agropecuária OesteConselho Nacional de Desenvolvimento Científico e TecnológicoEmbrapa Agropecuária OesteOliveira, Odair Honorato deCeccon, GessiCapristo, Denise PrevedelFachinelli, RicardoGuimarães, Amanda Gonçalves2022-07-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27090Pesquisa Agropecuaria Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e02729Pesquisa Agropecuária Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e027291678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27090/15032Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-01-23T13:40:22Zoai:ojs.seer.sct.embrapa.br:article/27090Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-01-23T13:40:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
