Abstract

This study was done to evaluate the quality of the maize sowing by a tractor-seeder-fertilizer applicator combine in no-tillage system, using different displacement speeds and motor shaft rotations. The experiment was conducted in randomized block design with four replications in a 4 x 3 factorial. The treatments consisted of four forward speeds, adjusted by gear schedules and three motor shaft rotations of the tractor. Operational speed, engine speed and slippage of the wheeled planter were monitored during sowing. Seed deposit depth, longitudinal seed distribution, seedling emergence velocity and mean emergence time were evaluated. The qualitative aspect of the sowing process showed that it is possible to opt for lower displacement speeds by gear scheduling and lower engine rotations, with best results obtained at the speeds between 3.5 and 5,0 km h-1.
