Corn test weight changes during drying

Dale R. Hicks, Department of Agronomy and Plant Genetics, University of Minnesota
Some of this year's corn crop will not reach normal maturity before the next killing freeze. As a result, maximum yield potential and normal test weights will not occur. Test weights in the low 50's(lb/bu) may be common in some areas the state, especially in the northern half of MN. Test weight can increase with artificial drying if the drying temperature is maintained below 180°F.

Harvesting lodged corn

Dale R. Hicks, University of Minnesota
(revised Sept 1)
We talked about harvesting the wind lodged corn in southwest MN at meetings in Luverne and Adrian and discussed harvesting in one direction and leaving one row unit empty to guide the combine. I have learned a lot about harvesting down corn since then and thought the information might be useful to those with down corn.

Harvesting immature corn and soybeans for forage after a killing frost

Paul Peterson, Jim Linn, and Dale Hicks, University of Minnesota Extension Service
Frost touched much of the state's corn and soybean acreage this past weekend. The degree to which the frost was a killing frost varies considerably, but a complete killing frost appears to have been the exception, not the rule. Where frost injury occurred without complete kill, it is too early to consider forage harvest because additional yield and forage quality accumulation is likely from surviving plant parts. However, where these crops were/are completely killed by frost before reaching optimum grain or even forage harvest maturity, harvesting as forage is a viable option. In addition, based on the delayed maturation of corn and soybeans to date, chances are good that there will many acres of these crops that will receive a killing frost before reaching maturity, so harvest as forage may still be one of the better options as the growing season plays out.

Drying, handling, & storing wet, immature, & frost-damaged corn

Bill Wilcke, Extension Engineer
Unusually cool growing season weather and early frosts can lead to wet, immature, and frost-damaged corn. This publication describes some of the harvest conditions you can expect after a cold, short growing season and some possible steps to deal with the crops that result from such a growing season.
