The sowing process can be affected by constructive differences related to the seeder, morphological and climatological conditions, depending on working speed used. performance of furrow opening components seeders is essential for obtaining good yields productivity maizecrops. This work aims evaluate maize with a Massey Ferguson tractor model MF 7370 power 125 kW pneumatic seeder-fertilizer as function its behavior at different displacement speeds. statistical design used was randomized blocks, six speeds, approximately (V1=2.0; V2=4.7; V3=6.5; V4=8.1; V5=10.3 V6=12.3 km h-1), crop, four replications, totaling 24 experimental plots. Soil mobilization parameters were evaluated: width depth, mobilized area, angle. As agronomic traits number days emergence, initial final population, grain yield. angle, depth furrowing fitted quadratic regression model, while sulcus had an increasing linear effect. Intermediate speeds V4 (8.1 h-1) showed highest values area lowest angle value, whereas V3 (6.5 presented yield (8902 kg ha-1).
