ABSTRACT THE effects of removing (thinning), crosshedging, and topping hedgerow trees were investigated as tree size management practices when harvested by hand and mechanical methods. Overall, compared with the hedgerow, tree removal reduced fruit yields only the 1st year whereas crosshedging reduced fruit yields 7% to 14% over all years. Annual tree topping reduced fruit yields an average of 20%. The efficiency of fruit removal for air and trunk shakers averaged 90% and were not generally affected by tree size management practices. Compared with hand harvest, the air and trunk shakers reduced fruit yields 15 and 8%, respectively.
