Resumo: | The common bean requires high levels of nitrogen (N) to achieve high productivity, which can be supplied, at least partially, by the biological nitrogen fixation (BFN). Two field experiments were carried out in the winter season of 2015 aiming to evaluate the effects of different cover crops, desiccation times and the agronomic performance of the common bean inoculated with rhizobia. The experiments were assembled in a randomized block design with four replications, in a factorial split-plot arrangement with two additional treatments (5x4x2+2). The factors were composed of five cover crops, four desiccation times, two seed inoculation treatments and two additional controls (TN = 90 Kg N ha-1 and T0 = without N and without inoculation). The variables analyzed in the cover crops were dry mass (DM) and total nitrogen (Total-N). With the common bean, the chlorophyll content (CC), the number of nodules (NN), the nodule dry weight (NDW), the shoot dry weight (SDW), the root dry weight (RDW) and the grain yield (GY) were evaluated. The results showed that the agronomic performance of the common bean was not affected by the desiccation times of the cover crops, although the amount of Total-N accumulated by cover crops was influenced by sowing times. Inoculation of the common bean promoted an increase in the NN, NDW, CC and SDW. Higher GY of the common bean was achieved with its cropping after Brachiaria brizantha, Brachiaria ruziziensis, millet and fallow. |

Com o objetivo de avaliar os efeitos de diferentes plantas de cobertura e épocas de dessecação no desempenho agronômico do feijoeiro-comum inoculado com rizóbio, foram conduzidos dois experimentos em campo, na safra de inverno 2015. Os experimentos foram implantados em delineamento de blocos ao acaso com quatro repetições, em esquema fatorial de parcelas sub subdivididas com tratamentos adicionais (5x4x2+2). Os fatores foram: cinco plantas de cobertura, quatro épocas de dessecação, dois tratamentos de inoculação das sementes e duas testemunhas (TN = 90 Kg N ha-1 e T0 = sem N e sem inoculação). As variáveis analisadas nas plantas de cobertura foram massa seca (MS) e nitrogênio total (N-Total). No feijoeiro-comum avaliou-se teor de clorofila (TC), número de nódulos (NN), massa seca de nódulos (MSN), massa seca da parte aérea (MSPA), massa seca de raiz (MSR) e a produção de grãos (PG). Os resultados mostraram que o desempenho agronômico do feijoeiro-comum não foi afetado pelas épocas de dessecação das plantas de cobertura, embora a quantidade de N-Total acumulada pelas plantas de cobertura tenha sido influenciada pela época de semeadura. A inoculação do feijoeiro-comum promoveu aumento do NN e MSN, do TC e da MSPA do feijoeiro-comum. Em Santo Antônio de Goiás obteve-se maior PG do feijoeiro-comum em cultivo após braquiária brizanta, braquiária ruziziensis, milheto e pousio.Universidade Federal Rural do Semi-Árido2017-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/574910.1590/1983-21252017v30n312rcREVISTA CAATINGA; Vol. 30 No. 3 (2017); 642-652Revista Caatinga; v. 30 n. 3 (2017); 642-6521983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5749/pdfOliveira, Ana Paula SantosSousa, Cleiton MateusFerreira, Enderson Petrônio de Britoinfo:eu-repo/semantics/openAccess2023-07-20T11:14:37Zoai:ojs.periodicos.ufersa.edu.br:article/5749Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:24.423565Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
