Resumo: The seed is considered the most important agricultural input, mainly because it carries genetic characteristics that determine the agronomic performance and it is responsible for the success of the crop establishment. Santa Catarina is the Brazilian state that showed a major evolution in irrigated rice seed quality over the last three decades, as became evident from samplings taken from rice growers at planting time. This study aimed to evaluate the rice seed quality used by farmers in Santa Catarina state, southern Brazil. Rice seed samples (307) were collected representing all rice- -producing regions of the state, in the 2007/08 season, and a form was completed with relevant information about each sample. The samples were sent to Epagri’s seed laboratory to determine purity, germination test, vigor and red rice infestation. The survey shows that the seeds used by farmers in Santa Catarina have high quality when purity, germination and vigor are considered, but about 17% of the samples are infested with red rice.

A semente é considerada o mais importante insumo agrícola, principalmente porque conduz ao campo as características genéticas determinantes do desempenho de uma cultivar, e ao mesmo tempo contribui decisivamente para o sucesso da lavoura. Santa Catarina é o Estado brasileiro que obteve a maior evolução na qualidade da semente de arroz irrigado nas três últimas décadas, demonstrada pela coleta de amostras das sementes utilizadas pelos agricultores. Este trabalho teve como objetivo realizar o levantamento da qualidade das sementes de arroz irrigado utilizadas pelos agricultores de Santa Catarina. Foram coletadas 307 amostras de sementes em todas as regiões produtoras de arroz irrigado no Estado no ano agrícola 2007/08. Por ocasião da coleta, utilizou-se um questionário para obter informações adicionais sobre a semente e a lavoura de cada agricultor. Em laboratório, foram realizadas as seguintes avaliações: análise de pureza, teste de germinação, teste de vigor e ocorrência de arroz-vermelho. Conclui-se que as sementes utilizadas pelos agricultores de Santa Catarina apresentaram alta qualidade, considerando pureza, germinação e vigor, porém 17% das amostras apresentam infestação por arroz-vermelho.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2020-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/741Agropecuária Catarinense Journal; Vol. 23 No. 3 (2010); 50-54Agropecuária Catarinense; v. 23 n. 3 (2010); 50-542525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/741/639Copyright (c) 2020 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessNoldin, José AlbertoKnoblauch, RonaldirMartins, Gabriela NevesDal Piva, Celso AntônioSchiocchet, Moacir Antônio2021-06-23T14:36:45Zoai:ojs.publicacoes.epagri.sc.gov.br:article/741Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2021-06-23T14:36:45Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
