Manejo e capacidade de campo efetiva de conjuntos sob o consórcio crotalária-guandu e mucuna-guandu em sistema plantio direto.

Abstract

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.
