Resumo: Corn (Zea mays L.) is one of the main commodities of Brazilian agribusiness, however, the sowing operation of this crop still presents challenges related to the performance of the metering mechanisms and operational speed, since these can affect the physical quality of the seeds and impair germination. The aim of this study was to evaluate the physical quality of maize seeds as a function of different metering mechanisms and operational speeds in a controlled sowing trial. The experiment was carried out at the State University, UNESP/Botucatu-SP, using five commercial models of seed dosers at four operational sowing speeds. The results showed that the metering model and the operational speed directly affected the physical quality of the corn seeds, reducing on average 3.17% their germination power. The sowing speed did not directly affect the water content of the corn seeds; however, it proportionally increased the number of damages. Regardless of the metering mechanism, operating speeds between 4 and 6km h -1, provided less damage to the seeds.

O objetivo deste estudo foi avaliar a qualidade física de sementes de milho em função de diferentes mecanismos dosadores e velocidades operacionais em ensaio controlado de semeadura. O experimento foi realizado na Universidade Estadual Paulista, UNESP/Botucatu-SP, utilizando-se cinco modelos comerciais de dosadores de sementes em quatro velocidades operacionais de semeadura. Os resultados mostraram que o modelo de dosador e a velocidade operacional afetaram diretamente a qualidade física das sementes de milho, reduzindo em média 3,17% o poder germinativo destas. A velocidade de semeadura, não afetou diretamente o teor de água das sementes de milho, entretanto, aumentou proporcionalmente o número de danos. Independentemente do mecanismo dosador, as velocidades operacionais entre 4 e 6km h-1, propiciaram menor intensidade de danos às sementes.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2022-10-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/682310.32404/rean.v9i3.6823Revista de Agricultura Neotropical; v. 9 n. 3 (2022): REVISTA DE AGRICULTURA NEOTROPICAL; e6823REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 9 No. 3 (2022): REVISTA DE AGRICULTURA NEOTROPICAL; e68232358-6303reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/6823/5207https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessParizotto, Nayara FrancieliCarpes Marques Filho, AldirMunhoz Venâncio de Oliveira, MarceloPereira de Souza, Flavia LuizeArbex Silva, Paulo Roberto2022-10-25T15:29:01Zoai:ojs.pkp.sfu.ca:article/6823Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2022-10-25T15:29:01Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false
