Resumo: This study was done to evaluate the quality of the maize sowing by a tractor-seeder-fertilizer applicator combine in no-tillage system, using different displacement speeds and motor shaft rotations. The experiment was conducted in randomized block design with four replications in a 4 x 3 factorial. The treatments consisted of four forward speeds, adjusted by gear schedules and three motor shaft rotations of the tractor. Operational speed, engine speed and slippage of the wheeled planter were monitored during sowing. Seed deposit depth, longitudinal seed distribution, seedling emergence velocity and mean emergence time were evaluated. The qualitative aspect of the sowing process showed that it is possible to opt for lower displacement speeds by gear scheduling and lower engine rotations, with best results obtained at the speeds between 3.5 and 5,0 km h-1.

O delineamento experimental foi em blocos ao acaso com 4 repetições em arranjo fatorial 4x3, com 12 tratamentos, constituídos de 4 velocidades de deslocamento, obtidas em função dos escalonamentos de marchas e de 3 rotações do motor do trator. Durante a semeadura, monitorou-se a velocidade de operação, a rotação do motor e o deslizamento dos rodados motrizes da semeadora. Após a semeadura, foram avaliados: a profundidade de deposição de sementes, a distribuição longitudinal de sementes no leito de semeadura, o índice de velocidade de emergência e o tempo médio de emergência. Os resultados mostraram que, sob o aspecto qualitativo do processo de semeadura para a cultura do milho, é possível optar por menores velocidades de deslocamento em função do escalonamento de marcha e menores rotações no motor, ressaltando-se que as velocidades de 3,5 até 5,0 km h-1 proporcionaram os melhores resultados.Universidade Federal de Viçosa - UFV2012-04-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/21910.13083/reveng.v20i2.240Engineering in Agriculture; Vol. 20 No. 2 (2012); 95-103Revista Engenharia na Agricultura - REVENG; v. 20 n. 2 (2012); 95-1032175-68131414-398410.13083/reveng.v20i2reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/219/170Silveira, João Cleber Modernel daFernandes, Haroldo CarlosLeite, Daniel MarianoTeixeira, Mauri MartinsFurtado Júnior, Marconi Ribeiroinfo:eu-repo/semantics/openAccess2023-01-19T13:01:04Zoai:ojs.periodicos.ufv.br:article/219Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:01:04Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
