This plot was planted on May 10th of 2013 and harvested on October 25th. 30" rows. Field received substantial hail late so yields weren't expected to be great. The plot also had a plot with different starter fertilizers right next to it that will reported in a different blog. The results:

This is one of the few plots this year where the 100day+ hybrids outyielded the earlier hybrids. Don't know why. Note the last hybrid though. P9675 is a 95-96 day corn and was originally put in at the end of the plot to show sidexside just how much yield gain can be acrrued by maxing out your hybrid maturity. P0533 is a 105day hybrid and even on a year such as this one where we didn't get an over supply of growing degree units, it outyielded the 96 day by 25 bu/a with only 3 points more of moisture. Keep in mind this was planted on May 10th also, not early-planted at all.
