| Sumario: | In an essay, carried out in 1997, the performance of an animal traction planter for direct drilling of black beans (Phaseolus vulgaris L.) was evaluated. The experiment was carried out in a distrofic dark red oxisol in the experimental field of the Agronomy School of the Federal University of the State of Goiás, Brazil. Two levels of mulching, three soil opener systems, and two coulter settings were compared. None of the treatments met the agronomic requirements for the black bean direct drilling. Lower mass and density of cover crop residues resulted in better seed distribution and higher plant population. The system with coulter fitted in the depth limiting wheel favored deeper fertilizer and resulted in lower uncovered seed percentage. Double disc opener presented shallower depth of fertilizer and more uncovered seeds, carrying out a lower plant population. KEY-WORDS: Zero tillage; planter machine; animal traction. |
