COMPARISON OF SYSTEMS OF AUTOMATED CROP AND SEMIMECHANIZED IN THE LOSS, MECHANICAL DAMAGE AND IMPURITY OF GRAINS IN THE CULTURE OF THE BEAN (Phaseolus vulgaris L.)
Keywords:
Bean, annual cultures, agricultural mechanizationAbstract
The mechanization of the crop of the bean still constitutes an obstacle for the expansion of the culture. Due to this fact, CNPAF is making an effort to the improvement of the species looking for favorable characteristics to the mechanized crop. The cultivar ‘Safira’ fulfills this aim. In this sense, an experiment was carried out at Fazenda Três Irmãos, in the district of Santa Helena of Goiás (GO). Three crop systems were tested in order to evaluate losses of grains and the quality of the picked product, through analysis of broken grains and sludges. The results demonstrated that the mechanized crop of bean concerning the cultivar ‘Safira’ is viable. The self-driven retirement causes a smaller loss of grains, but the mechanical damage is higher; the retirement-thrashing showed satisfactory loss, despite of requiring adequate handling.
KEY-WORDS: Bean; annual cultures; agricultural mechanization.
