The performance of the seeder is entirely attributable to the interaction of the tires with the ground. Thus, the aim of this study was to evaluate the grain weight (g/m), seed population (nº/ha), tire performance (%) and displacement efficiency (%), at different loads in the continuous seeder-fertilizer flow and tire inflation pressures, in conventional system and no tillage system. This experiment was carried out in 2015; it was performed using randomized blocks with four replications in a 3 × 3 factorial. There were three loads in the continuous flow seeder (100, 50, and 10%), and three inflations of the tires (20, 40, and 60 psi), totaling 36 plots. In both planting systems, when the tire of the seeder is at 60 psi and loads below 100% of fertilizer and seeds, the deposited seed population is less than ideal. In conventional tillage, the tire inflation pressure is less harmful to their performance on the ground.

O experimento foi conduzido em 2015, com delineamento em blocos ao acaso, em fatorial 3 × 3, com quatro repetições. Foram três cargas na semeadora-adubadora de fluxo contínuo (100, 50 e 10%) e três inflagens nos pneus (20, 40 e 60 psi), totalizando 36 parcelas. Em ambos os sistemas de plantio, quando os pneus da semeadora estavam preenchidos com 60 psi e cargas abaixo de 100%, a deposição da população de sementes é menor do que a ideal. Em sistema de plantio convencional, a inflagem dos pneus é menos prejudicial ao desempenho da semeadora.Palavras-chave: plantabilidade, manutenção de máquinas, Sorghum bicolor
