Resumen:
The present research was developed to study the displacement speed, field capacity
accomplishes for each set (tractor-equipment) and the production of dry mass of 2 marriages of coverings
crops, in experiment realized in area of the Laboratório de Máquinas e Mecanização Agrícola (LAMMA),
of the Departamento de Engenharia Rural, FCAV/UNESP, Jaboticabal-SP. The marriage of covering
crops utilized was: Crotalária + Guandu (C+G) and Mucuna + Guandu (M+G), handling under 3 systems
(mechanical, with grinder of straws and cleared for cultivation and chemical, with herbicide) in
customized blocks array and factorial esqueme, with 4 repetitions, in total of 24 portions. The results
allow to check that the handlings did not influence in the marriage of dry mass at 30, 97 and 125 days
after the implant and that at 30 days after the implant, the handling with grinder of straws show the most
value of dry mass. The real forward speed and effective field capacity show influence by the three
handlings. The grinder of straws proportion the biggest speed, and the handling with herbicide, the biggest
effective field capacity.
