This study was done to evaluate the influence of sowing depth and vertical load on the press wheel on the physical characteristics of soil and agronomic characteristics of corn. The experiment was done in the completely randomized design with four vertical load (62.7; 160.7; 258.7 or 356.7 N), three sowing depths (0.03; 0.05 or 0.07 m), with three replications. Following variable were evaluated: resistance to soil penetration, losses at harvest, number of days for plant emergence, and fresh and dry matter yield. The resistance to penetration was affected by different loads on the press wheels. There was no effect on the number of days to plant emergence, dry and fresh matter production, and losses during triturating processes.
