A study was conducted to examine how pecan yield from individual trees can be correlated to pecan yield measurements from a mechanical harvester equipped with a yield monitor that weighs pecans as they are dropped into a wagon. For purposes of determining individual tree yields, a method was devised for taking the yield of pecans and foreign material collected by a mechanical harvester close to the trunk of the tree and extrapolating to determine the entire yield for that tree. Data were collected for 2 years on 12 pecan trees. Total pecan yield for a tree was closely correlated (r2 = 0.84) to the gross weight of pecans (pecan yield plus foreign material) in a 4 m section of harvested material. It is expected that comparison of tree yields could help improve pecan grower's selection process when removing unproductive trees and help researchers assess yield differences for test treatments.
