*Based on a fixed per-acre cost related to 

 equipment, picker housing, picker travel, etc. 

 plus a per-bushel cost related to harvesting. 

 ** Based on yields reported in Table 2. 



differences in yield and maintenance costs may 

 decline; however, the differences in packout may 

 increase. Rough estimates comparing the costs 

 and returns for the first 20 years of the planting 

 suggest that trees on M.9 trained to a trellis can 

 net $10,000 per acre more than trees on M.7, 

 accounting for differences in training, spraying, 

 yield, and packout. It is important to note that 

 the cost estimates used in this study could vary 

 greatly from those for an individual farm, but
