Corn-on-Corn Plot East of Dumont

This plot is found east of Dumont 8-9 miles. It was planted on April 27th, and harvested on October 4th, 2012. This plot was actually weighed by our neighboring Pioneer dealers in Herman (Lakeside Seed) for one of their customers, but it provides information that we normally don't get to see so I am presenting it to you here. The plot compared seven hybrids on both corn stubble from 2011, and soybean stubble from 2011.

- With pressure on to plant more corn-on-corn, many growers ask us what to plant on those fields to maximize yields. We're not going to suggest that P9917 and P9910 are going to actually increase yields (as the above results show), but it does show that they were most likely to show yield loss from corn-on-corn rotations. The above also shows that although a typical yield loss from corn-on-corn would normally be 10%, we experienced a lot less of the negative effects in 2012.
