A 1985 study (Midsouth weather and acres per 2-row picker) indicates that if the producer begins harvest on October 2 when he could have started on September 25 (one week late), first pick will require an additional 9 calendar days, completion of second pick will require an additional 18 days, and harvest is completed 34 calendar days later than necessary. Realized yield is reduced by 21 percent and revenue is reduced by 22 percent.
