Starter Demo Results and Discussion With a premium starter comes a premium price and it is harder to pay for itself in a growing season such as we had in 2021. We planted in ideal soil temperatures and moistures that allowed for good early growth and development of the corn plant. Despite the good growing conditions in this demo the plants were shorter and lighter colored all season long. As we approached grain fill we observed ears that were tipped back where no starter was applied and estimated a benefit to the

starter around 10-12 bu./ac. As you see in the results table the yield differences were 5-7 bu./ac. We observed that the excellent conditions and adequate water during grain fill aloud that gap to close
