Abstract

This article describes the effects of three seeding unit designs on plant residue clearance along the central line ofdirect corn (Zea Mays L.) seeding and the subsequent influence on crop emergence. The equipment assemblies testedwere three different combinations of the implements turbo coulter blade (TCB), double disc opener with a seed presswheel and covering/packing wheels (DDO), notched disc row cleaner with a track wheel or floating star cleaner (RC)as follows: (1) TCB+DDO, (2) RC+TCB+DDO and (3) TCB+RC+DDO. Under the field conditions tested, residueclearance before the cutting action of the turbo coulter blade (combination 2) gave rise to the best crop stand and cropuniformity. The seeding assembly that moves soil and clears away plant debris along the seeding furrow shows a directeffect on seed emergence.
