【 摘 要 】

Traction and power required by a seed drill with 14 holes was evaluated in the oat (Avena strigosa L) seeding. The experiment was carried out in a Haplortox, in an area with mean slope of 0.03 m m-1. The experimental design consisted of four treatments (two seed deposition depths and two displacement speeds) with four repetitions, totaling sixteen experimental plots of 4 x 50 m (200 m2), in no tillage system on corn crop residue. It was concluded that the increase of the seeding depth of 1.97 cm to 2.68 cm, the draft requirement increased from 3.78 to 5.51 kN. The speed increase from 5.24 to 7.09 km h-1, caused an increase of 6,90% in the traction force of the drawbar.
