High cost and unavailability of labor for hand harvest has resulted in domestic chile production declining even as consumption grows. Mechanization is necessary but has resisted four decades of diligent research effort. Five picking mechanisms were tested in five cultivars in two fields in New Mexico in 2008. Harvest efficiency was 42% to 90%, with 11% to 45% mechanical damage for a net collection of marketable peppers that ranged from 28% to 80% of total yield. An inclined counter-rotating open-helix design with a clear product path had the highest harvest efficiency and lowest percentage of product damage. Cultivar response to mechanical harvest provided feedback for the New Mexico State University chile breeding program.(Download PDF) (Export to EndNotes)
