A simple system has been developed to generate yield maps of hand-harvested
citrus in a reliable, low-cost manner using a commercial GPS recorder. Ind
ividual 0.7-m(3) container locations are mapped to indicate yield variation
s within a citrus block. Further future refinements are discussed. The syst
em is applicable to other manually harvested crops and harvesting systems.
