Abstract

This study was carried out to evaluate the influence of the combination of displacement speed and the load applied by the compacting wheel of a seeder-fertilizer machine on the emergence of the seedlings and initial development of the maize crop in the no-till system. The study was done with the use of three displacement speeds of the seeder machine (1.11, 1.67 and 2.22 m s-1) in combination with four loads applied by the compacting wheels (119.26, 131.11, 257 and 339 N). The pressure was adjusted using the compressing pressure of the two springs in each planting unit of the seeder machine. The load of 339N caused a lower seed deposition depth than the load of 131.11. The maximum flattening of soil layer on the seed occurred with the load of 339N, due to the pressure exerted by the compressing wheels. There was no interaction between the factors, as well as no significant difference between the evaluated speeds. The load applied by the compressing wheels and the displacement speeds used for seeding had no influence on emergence and initial establishment of the maize crop.
