Resumo: | The supply of nitrogen (N) to the carioca bean plant via inoculation with Rhizobium tropici can prevent competition with the weed community by allowing the crop to absorb the nutrient available in the soil. On this basis, this study proposes to examine the period before weed interference (PBI) in the carioca bean plant following inoculation with R. tropici or N topdressing. The experiments were carried out under field conditions during the summer seasons of 2014 and 2015. A randomized-block experimental design with four replicates was adopted, in a 2 × 11 factorial arrangement (common bean plant inoculated or topdressed with N × 11 periods of coexistence with weeds, namely, 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, or 90 days after emergence [DAE]). Nitrogen topdressing increased the crop's tolerance to coexist with weeds from 6 to 14 DAE, compared with inoculation with R. tropici The PBI for the inoculated common bean plant was 24 and 16 DAE in the years 2014 and 2015, respectively. For the N-topdressed plant, the PBI was 30 DAE in both years. |

Portanto, o objeto deste estudo foi avaliar o período anterior à interferência (PAI) no feijoeiro carioca com inoculação com R. tropici e com adubação nitrogenada em cobertura. Os experimentos foram conduzidos em condições de campo durante as safras de verão de 2014 e de 2015. O delineamento experimental foi de blocos casualizados com quatro repetições em esquema fatorial 2x11 (feijoeiro com inoculação ou com adução nitrogenada em cobertura x 11 períodos de convívio com as plantas daninhas: 0, 7, 14, 21, 28, 35, 42, 49, 56, 63 e 90 dias após a emergência (DAE). A adubação nitrogenada em cobertura aumentou a capacidade da cultura em conviver com as plantas daninhas de 6 a 14 DAE quando comparada a inoculação com R. tropici. O PAI para o feijoeiro inoculado foi de 24 e 16 DAE em 2014 e 2015, respectivamente. Para o feijoeiro com adubação nitrogenada em cobertura o PAI foi de 30 DAE em ambos os anos.UEL2022-02-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionexperimento de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4429610.5433/1679-0359.2022v43n2p855Semina: Ciências Agrárias; Vol. 43 No. 2 (2022); 855-868Semina: Ciências Agrárias; v. 43 n. 2 (2022); 855-8681679-03591676-546Xreponame:Semina.
