Estimated corn yield adjusted to 14% moisture ranged from 6,937 to 11,044 kg/ha. Pre-harvest ear losses ranged from 0 to 42 kg/ha. Total corn combine losses ranged from 36.2 to 320.6 kg/ha (0.3% to 3.6% of yield). Of this loss, header ear loss accounted for the largest portion with 0 to 237 kg/ha. Reduction in ground speed would benefit separation losses in corn. But not surprisingly, lodged corn can increase header ear losses by more than any other source of loss.(Download PDF) (Export to EndNotes)
