- By the results you can see that the May 9th planting date did not treat the later-maturing hybrids very well. Also in the plot are comparisons of the versions of P9910 and P9675 to the new versions for next year which is the "Refuge-in-a-Bag" versions labelled "amx". As you can see, the new versions and the old versions yielded the same so we should be able to sell the new versions with confidence that the yield will be the same. Some of our competitors are struggling with their "Refuge-in-a-Bag" versions not yielding as high as their lesser-technology versions. We also tested some starter fertilizers and such in this plot and we will present those results after we've looked at the data more.
