Coffee Yield MappingPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 021166, 2002 ASAE Annual Meeting . (doi: 10.13031/2013.9158) @2002Authors: Luiz A. Balastreire, John K. Schueller, J.R. Amaral, J.C.G. Leal, F.H.R. Baio Keywords: coffee, precision agriculture, yield mapping, mechanical harvesting, load cells An automatic weighing system was developed and interfaced to a GPS for use during mechanical coffee harvesting. The canvas hopper and load cells system successfully measured crop yield. The obtained results showed a great spatial variability in coffee yield, ranging from 2.1 to 16.0 Mg/ha in a 1.1 hectare plot in a farm in So Paulo state. (Download PDF) (Export to EndNotes)
