University of Idaho educator: Corn maturing earlier this year

By  | 

JEROME, Idaho (KMVT/KSVT) - Corn observers see corn maturing more quickly this year. University of Idaho educator Steven Hines from the extension of Jerome County said there are no major concerns.

Hines said the corn matured about two weeks earlier.

"Just observations around the valley, as well as some different research demonstration trials I worked in," he continued. "It seemed like the silage varieties were two weeks ahead of what they should've been for the relative maturity of this specific variety we were looking at."

A reason they matured earlier this year is because of hot temperatures, he said.

"Corn will grow as long as the temperature is 60 degrees or higher. A lot of evenings were well above 60 degrees," Hines said.

He said that aided in the corn growing.

"As far as it maturing and drying out, a couple things," he continued. "One, the heat units, but also we had a frost, and when corn gets frosted it is a... season grass. So once it's frosted hard enough, it will die, and that starts the drying out process as well."

Early maturing corn affects producers and does not affect others.

To determine the moisture range, the wet weight of the corn is taken, then dried down in an oven. Then the difference will tell you the percentage of moisture, he said.

For silage corn, the moisture range should be somewhere between 68 to 70 percent. For cereal corn grain, it should be about 15 percent on the kernel or less.
