 note = {Studies on labor inputs in Japanese apple orchards were reviewed. Analysis of the statistical data suggested that labor inputs tended to increase with fruit yield in an orchard. The apple growing system in Japan is far more labor-intensive than in any other country. One of the reasons is that heavy flower and fruit thinning is mainly done by hand to raise big apples, which often weigh more than 280g. Heavy leaf thinning by hand is a task done only in Japan just before harvest season to improve fruit appearance. However, it is necessary to reduce labor inputs, since apple growers are now under pressure to expand orchard size to secure a profit. This report examines the effect on labor-saving of lowering tree height in an orchard.},
