Abstract

A break in the Midwest heat storm is a good thing, but is it good enough for the corn crop? A few days of temperatures exceeding 93 F – like we experienced in July – are “bad” for corn production, but consecutive days of the high temperatures are especially bad. When the heat comes as silking gets underway – as it did this year – the negative aspect is increased. Our mail indicates that ears did not pollinate well in at least major parts of fields across the Midwest and the locally grown sweet corn we have been consuming verifies that there are pollination problems this year. Many reported silking problems in late July. Shallow kernels, missing kernels, and tip back are common in field corn this year. All of this unfortunately sounds similar to what we experienced last year.
