Three commercially-available cotton yield monitors were tested in five grower-owned fields in south Georgia during the 2000 harvest season. Each harvested load was weighed and compared to the three yield monitors. Yield maps from each yield monitor were also produced by the respective software packages and compared. Feature comparisons of each monitor were included.

Prior to the 2000 harvest, the Team evaluated the current status of the Zycom (now Agriplan, Inc., Stow, MA), Micro-Trak, and FarmScan cotton yield monitors. It was evident that Zycom and FarmScan had made upgrades available for their respective systems. Micro-Trak apparently had made no significant changes since the Team last updated the installed Micro-Trak system in 1998. Therefore it was decided that in 2000 the Team would harvest and map with AgLeader, FarmScan and Zycom systems.

This report provides results of the Team’s simultaneous field testing of the AgLeader, Computronics/FarmScan, and Agriplan/Zycom cotton yield monitors during the 2000 harvest season in south Georgia. The unique ability to simultaneously operate all three yield monitors on the same picker allowed for direct comparisons of the three systems over the same harvest areas. Typical field maps as well as data will be compared.
