I was in the area of Jefferson City, Missouri last week and talked to a local farmer.
He said that farmers (without irrigation) who planted in March had a good looking corn crop. Those who waited until after April 10 for Federal Crop Insurance had a poor crop.
Is that what you are seeing?
Seems that way. I think that there are a number of farmers along the river who delayed planting to clean up the silted areas after the floods last year.
