Guess the yield

23 Sep 2011 05:56 AM
The featured chart presents accumulated growing degree day (base 50) departures from 1 May to 1 Oct for each of the past 10 years for Ames. The number at the end of the line is the reported corn yield by the USDA for Story County (the county of Ames). The total season departure does not tell the entire story for the resulting corn yield. The black line is so far this year, wish to guess the yield based on this chart? :)

Good: 25
Bad: 7
