Resumo: Upland rice (Oryza sativa L.) sowing with five sowing/fertilizing machines, EG 212-AS, PAR 3000, PST 2, MP 2000, and PP Solo models, working at three different displacement velocities, on a typic Haplustox soil, on two soil tillages (conventional and minimum tillage) was studied. The machines showed different performance in relation to operation velocity, sowing capacity and fuel consumption. Seed distribution, sowing depth and seed integrity were not affected by increasing machine operation velocity. There were less seeds per meter and sowing was deeper at minimum tillage. Fertilization depth was similar for all machines, independently of operation velocity and soil tillage. The worm gear fertilizer dosers were more suitable than the rosette or rotor ones. Rice sown with PST 2 yielded better than sown with EG 212-AS.

As máquinas apresentaram desempenho diferenciado quanto à velocidade de operação, quanto à capacidade de plantio e quanto ao consumo de combustível. A distribuição e os danos mecânicos nas sementes e a profundidade de semeadura não foram afetadas pelo acréscimo na velocidade de operação das semeadoras. No solo com preparo reduzido houve menor distribuição de sementes por metro e maior profundidade de semeadura. A profundidade de adubação foi semelhante com todas as máquinas, independentemente da velocidade de operação e do preparo do solo. Os dosadores de adubo do tipo rosca-sem-fim foram mais eficazes que os dos tipos roseta e rotor. A produtividade do arroz foi maior nos plantios realizados pela PST 2, a qual diferiu significativamente da proporcionada pela EG 212-AS.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, José Geraldo daKluthcouski, JoãoStone, Luiz FernandoAidar, HomeroOliveira, Itamar Pereira deFerreira, Evane1998-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4815Pesquisa Agropecuaria Brasileira; v.33, n.1, jan. 1998; 63-70Pesquisa Agropecuária Brasileira; v.33, n.1, jan. 1998; 63-701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4815/6933info:eu-repo/semantics/openAccess2014-11-10T17:26:00Zoai:ojs.seer.sct.embrapa.br:article/4815Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-10T17:26Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
