| It was compared the performance of the metering mechanism of corn seeds (Zea mays) in direct seeding in an area of 200 ha, a property in Piraí do Sul, State of Paraná - PR, in Brazil. It was seeded 4 maize hybrids, 50 ha of each, with seeds of different sieves. The experiment was conducted in a randomized block design (RBD), with 3 treatments and 9 repetitions for each corn hybrid. The treatments were the pneumatic seed of metering mechanisms, horizontal perforated disc with and without ramp®. The plots were 40 m² and were distributed at the early, middle and late sowing. The variables analyzed in each corn hybrid were initial population, faulty spacing, multiple spacing, acceptable spacing, and yield components. As there were no significant differences... |

| ABSTRACT The aim of this study was to analyze the influence of space between the base and intermediate base on quality of seed distribution with a horizontal seed plate. The experiment was carried out in 2012 at the Laboratory of Agricultural Mechanization of the State University of Ponta Grossa - PR, Brazil, using a sowing simulation device. The experimental design was completely randomized design with four treatments and seven replications. Treatments consisted of spaces (0, 1, 2, and 3 mm) between the base and intermediate base. Replications were defined by 250 spacing between seeds. Corn (Zea mays L.), soybean (Glycine max L. Merrill), and sorghum (Sorghum bicolor Moench) seeds were tested. The analyzed variables were faulty, multiple and acceptable... |
