The Indiana Ag Statistics Service issued final county yield estimates recently. The numbers were actually available before March 1. Many people were anxiously awaiting the numbers this year, especially in counties where yields were sub-par. Farmers who had crop insurance GRIP policies that are calculated after county average yields are released were anxious to learn how much their payment would be, and for the checks to finally begin arriving, which couldn't happen until the numbers were released.
A quick assessment of the corn yields or glance at the corn yield map for bushel per acre estimates confirms what most suspected. Where the drought was worst, yields tended to be lower. That was especially true in southwestern, west-central and central Indiana. There were also spots of lower yields in northeast Indiana, which was hit hard early but then received some relief before other areas of the state.
Twenty Counties posted yield averages of 65 bushels per acre or less. All of those 20 were either south of U.S. 40, a traditional boundary line from northern to southern Indiana, or else U.S. 40 runs through or just south of the county.
This map illustrates county estimates for corn yield in 2012. Counties without numbers didn't report enough information for NASS to make an estimate. Click the image for a larger version.
The counties are, lowest to highest in yield in bushel per acre: Orange, 30.1: Owen, 41, Morgan, 42.3, Monroe, 44.7; Warrick, 51.1; Harrison, 52.2; Lawrence, 52.8; Floyd, 55.7; Washington, 57.8; Pike, 57.8; Johnson, 58.1; Hendricks, 58.3; Vanderburgh, 60.4; Clay, 61.2; Putnam, 61.4; Dubois, 62.1; Shelby, 62.4; Switzerland, 63.2; Parke, 64,2; and Gibson, 64.8.
If you have a GRIP policy, your crop insurance payment is completely tied to county yield. Your own yields do not affect your payment. The coverage is more expensive, but can generate larger returns if you happen to farm in a county where the yield average was low for 2012. If you have a Revenue-based policy, it is not affected by county yield estimates.
