Yields. Typical annual yields for lemons are measured in 900-
pound field bins per acre, but are typically sold by packed
cartons weighing 37.5 pounds, although the industry often
refers to them as 40-pound cartons. A 900-pound bin is
calculated as either 23 or 24 cartons. Packed cartons
represent 80% of the fruit picked. The remaining 20% may go
to juices or a small percentage may be culls. Yields from the
third year to full production for field bins, boxes, and cartons
are shown in Table E.
