Resumo: | The culture of rice (Oryza sativa L.) is very affected by several diseases, in sowing, the rice seeds remain on the soil surface, these can become a source of inoculum for brusone and brown spot. However, studies are needed to intensify this knowledge, since it is little studied in the state of Amazonas. The present study aimed to evaluate the severity of the diseases brusone and brown spot on the leaf, grain spot and brusone on the panicle of rice submitted to different sowing systems in the rainy season. The present work was carried out in the field in the rainy season in the experimental farm of the Federal University of Amazonas - IEAA, located on the BR 319 at km 5 towards Humaitá -AM - Porto Velho - RO. The different sowing systems were evaluated; furrow sowing, incorporated sowing, non-incorporated sowing, pre-germinated sowing. In conclusion, in all treatments there was incidence and severity for both brusone and brown spot, however, some treatments showed the lowest mean incidence and severity. The treatment T6- system of sowing in normal incorporated furrow was the one that had the lowest average among the treatments, the sowing system in which the seeds are exposed on the soil surface were the ones that presented the highest averages of incidence and severity. |

No entanto, se faz necessário estudos que intensifiquem este conhecimento, uma vez que o mesmo é pouco estudado no Estado do Amazonas. O presente estudo teve o objetivo de avaliar a severidade das doenças brusone e mancha parda na folha, mancha dos grãos e brusone na panícula do arroz submetido a diferentes sistemas de semeadura no período chuvoso. O presente trabalho foi realizado a campo no período chuvoso na fazenda experimental da Universidade Federal do Amazonas – IEAA, localizado na BR 319 no km 5 no sentido Humaitá -AM – Porto Velho - RO. Foram avaliados os diferentes sistemas de semeadura; semeadura em sulcos, semeadura a lanço incorporado, semeadura a lanço não incorporado, semeadura a lanço pré-germinado. Concluindo que em todos os tratamentos houve a incidência e severidade tanto para brusone quanto para mancha parda, entretendo alguns tratamentos apresentaram as menores médias de incidência e severidade. O tratamento T6- sistema de semeadura em sulco normal incorporado foi o que teve a menor média entres os tratamentos, o sistema de semeadura em que as sementes ficam exposta na superfície do solo foram os que apresentaram as maiores médias de incidência e severidade.5SimBrasilIEAA - Instituto de Educação, Agricultura e Ambiente (Humaitá)Humaita (AM)Agronomia - Bacharelado - HumaitáRadmann, Vaírtonhttp://lattes.cnpq.br/8080427529749166Souza, Moisés Santos deFreitas, Renildo Melo deManejo do solo, da água e de plantas na AmazôniaMelo, Handerson José da Silva2023-11-06T14:15:01Z2023-11-06T14:15:01Z2023-07-04info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesishttp://riu.ufam.edu.br/handle/prefix/7162porinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFAMinstname:Universidade Federal do Amazonas (UFAM)instacron:UFAM2023-11-06T14:16:29Zoai:localhost:prefix/7162Repositório InstitucionalPUBhttp://riu.ufam.edu.br/oai/requestopendoar:2023-11-06T14:16:29Repositório Institucional da UFAM - Universidade Federal do Amazonas (UFAM)false |
