Agronomy Talk: Short Husking

Author: Eric Wilson

Short husking is best described as “corn ears outgrowing their husks.” It results in more exposure of the ear tips to environmental conditions and increases the potential for reduced grain quality.

Stalk Rot in Corn? Time to Prioritize Harvest!

Author: Austin Scott

Harvest time is finally here and for most of us in the South, this will be the year to forget! Parts of Tennessee encountered the worst drought we’ve seen since 2012. On the other end of the spectrum, parts of Kentucky, southern Indiana, and southern Illinois caught more rain than they could handle for most of the year. The Missouri Bootheel couldn’t make up its mind if it wanted to be too dry or too wet! All of these crazy environmental conditions have led to some serious standability issues in our corn. Just about every corn field I’ve been in recently has shown signs of premature death and stalk rot. This is something we see every year, but some years are worse than others and may require a little more planning before harvest.

Stalk Quality and Harvest Prioritization

Author: Brent Minett

Stalk quality can be negatively affected by three factors: disease, nutrient deficiency, and environment. Fungal diseases like fusarium, anthracnose, and gibberella stalk rot cause decay of the internal pith tissues of the stalk. Nitrogen deficiency can lead to the ear cannibalizing the stalk to feed itself. Extended straight line winds in excess of 60 mph can cause any hybrid to lodge; especially those fields that have experienced stress from the other two factors. Harvest prioritization will be especially important this fall.

Concerns for Corn and Soybeans Heading Into Harvest

Author: Chad Kalaher

Record precipitation totals for June have caused concern for corn and soybeans heading into harvest. Many corn fields lost nitrogen and will have a limited ability to adequately fill kernels. Because of this, I expect many corn fields will have ears displaying aborted kernels. In addition, saturated soils may have pre-disposed corn plants to stalk rot infection.
