Resumo: | The effect of pre-crops on the inoculum potential (IP) of arbuscular mycorrhizal fungi (AMF) and yield of cassava was evaluated on a Red-Yellow Podzolic soil in the field. The experiment was carried out at Embrapa-Centro Nacional de Pesquisa de Agrobiologia (CNPAB), Seropédica, RJ, Brazil, in plots with 30 m2 arranged in a randomised block design with four replications. As pre-crops, four legume species were used: Canavalia ensiformis, Mucuna aterrina, Crotalaria juncea and Cajanus cajan; and a grass Sorghum bicolor (BR 005) in relation to plots, without plants. After a grow period of 82 days, at the same plots, cassava stakes were planted, which were grown for eight months. The yield of cassava roots ranged from 12.76 to 17.20 ton ha-1, although no statistical significant effects were found between the treatments. There were 16 AMF species identified, and some of them had a significant frequency changement after the growing cycles. The number of infective propagules were significantly increased after sorghum crop in relation to plots without plants. It was showed that identification of plant species capable to increase the IP in the field soils may be a good alternative way to solve the problem of inoculum production to mycotrophic crops in the field. |

O experimento foi conduzido no campo experimental da Embrapa-Centro Nacional de Pesquisa de Agrobiologia (CNPAB), em solo Podzólico Vermelho-Amarelo, localizado no Município de Seropédica, RJ, em parcelas experimentais de 30 m2, dispostas em delineamento de blocos casualizados com quatro repetições. Os pré-cultivos constaram de Canavalia ensiformis, Mucuna aterrima, Crotalaria juncea, Cajanus cajan e Sorghum bicolor (BR 005) e o tratamento-controle (solo mantido sem plantas). Após um período de 82 dias de crescimento, sobre as mesmas parcelas cultivou-se mandioca, por oito meses. A produtividade de raízes de mandioca variou de 12,76 a 17,20 t ha-1, porém não foi detectada diferença estatística entre os tratamentos. Foram identificadas 16 espécies de fungos micorrízicos arbusculares e foi constatado que o número de esporos de algumas espécies sofreu alteração da sua freqüência de ocorrência com os cultivos. O pré-cultivo com sorgo aumentou o número de propágulos infectivos em relação ao controle, demonstrando que o uso de espécies de plantas com capacidade para elevar o potencial de inóculo pode ser um bom caminho alternativo para resolver o problema de produção de inóculo para culturas micotróficas em campo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSouza, Francisco Adrino deTrufem, Sandra Farto BotelhoAlmeida, Dejair Lopes deSilva, Eliane Maria Ribeiro daGuerra, José Guilherme Marinho1999-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5516Pesquisa Agropecuaria Brasileira; v.34, n.10, out. 1999; 1913-1923Pesquisa Agropecuária Brasileira; v.34, n.10, out. 1999; 1913-19231678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5516/2707info:eu-repo/semantics/openAccess2012-02-13T11:38:31Zoai:ojs.seer.sct.embrapa.br:article/5516Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-13T11:38:31Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
