Abstract
A labor tracking and yield mapping system for manual citrus harvesting was developed and evaluated in twocommercial harvesting operations in Florida. The system consisted of button recognition and barcode units, integrated witha differential global positioning system (DGPS) unit mounted on a truck, which was used to handle fruit collection containers(tub or bin) in the citrus grove. When the truck operator stopped to load each full tub or bin, the button and barcode of theharvester who filled the container was activated. This action recorded the number or name assigned to the harvester and theDGPS location of the container. The button unit was more reliable and was designed with an audible (alarm) and a visible(light) feedback to provide the truck operator verification of the recorded information. The system tallied the number ofcontainers each harvester had harvested for the day and allowed the entry of other information pertinent to the harvestingoperation. The DGPS data were used to map the yields with ArcView software. Field tests showed the labor tracking systemwas reliable and user friendly.
