Abstract

Results of investigations of human energy expended by orange pickers show that pickers are 25% more efficient when picking fruit from the ground than during general picking. Picking fruit from a ladder is not appreciably less efficient than general picking. ladder-carry and setting require twice the energy per unit of time as general picking.
