This is the time of year when questions about replanting or late planting are asked.
There is no need to guess about the effects of such a decision. UWEX Publication
A3353, "Corn Replanting or Late-Planting Decisions" is an excellent summary
of previous experience dealing with the effects of this type of decision in Wisconsin.
To make economically sound judgements, planting date, plant population, and hybrid
maturity relationships must be known and used quickly to make the decision. It still
might be beneficial to replant severely depleted stands, but yield potential of
corn is currently dropping at the rate of 1-3 bushels per acre per day. A poor early
planted stand may be "better" compared to replanting. Maturities should
be adjusted earlier for any corn planted now. A3353 gives guidelines for determining
the appropriate maturity, specific procedures and data to use for your situation
