Avaliação das caracteristicas operacionais de um conjunto trator-semeadora em três sistemas de manejo do solo e três velocidades na operação de semeadura da cultura do feijão (phaseulus vulgaris).

Abstract

The present work had as objective to evaluate the operational characteristics of a group tractor-seeders, during the operation of seedling of the culture of the bean (Phaseulus vulgaris), in three systems of handling of the soil (no tillage, plantation chiseling and conventional plantation), with three displacement speeds (3,0; 5,0 and 7,0 Km.h-1). It was evaluated the characteristics of the group as the consumption of fuel, skating, field capacity and speed. The data were analyzed considering an experimental design in split plot blocks, with the handling of soil in the parcels, the speeds in the subparcels, with five repetitions. The data were submitted the variance analysis at a level of significance of 5% through the test Tukey. For the theoretical field capacity the values increased in agreement with the increase of the speed. The direct plantation presented the largest values of the dependent variables, in the marches 2 and 3. In the analysis of the skating, the plantation chiseling presented larger values of the variables.
