You should fertilize corn when planting and late in the growing season. More Info: Assuming the soil pH is unknown, when initially planting corn till into 100 square feet of soil 3-4 pounds of a commercial fertilizer such as 12-12-12. As soon as the plant has reached a height of 16-18â high side dress the plant with additional fertilizer at a rate of one tablespoon per hill. Fertilize the soil not the plant and water deeply. The best way to tell exactly how much fertilizer and/or soil amendments you will need is to have your soil tested.
If we look at how late planted corn yielded in 2014 we find that there we saw some of the highest corn yields in the state from corn planted between May 5 and May 15. Some of which were over 300 bu per acre. However, after May 15 there are several factors that begin to negatively affect corn yield. 1  First, the decrease in days between planting and silking starts to have a major impact on yield. 2  Second, late-season corn diseases such as southern rust become concerns when planting after May 15.
