Iowa Corn Is Growing Fast, Ready To Tassel

Iowa Corn Is Growing Fast, Ready To Tassel

Weekly statewide survey shows warm, dry weather last week was good for crop development. Report released July 5 says 82% of Iowa's 2011 corn crop is in the "good to excellent" category.

Have you seen any cornfields tasseling yet in Iowa? On July 6 there were reports of tassels beginning to show in some early-planted fields in the southern part of the state. Also, a reader of this Wallaces Farmer online daily e-newsletter says a few tassels are beginning to shoot in some early-planted fields in northwest Iowa.

Lynn Brandt, a hail adjuster for Rain

In the next week to 10 days you'll hear about a lot of fields in Iowa tasseling, says Chip Mathis, who farms near Elkhart in central Iowa. Most of the corn and soybeans in northern Polk County where he's located look very good, he says. There are a number of spots near the Skunk River that had water standing in fields in June, which had about double the normal rainfall. These field areas where water stood are stunted and the crop is short. "However, my soybeans are doing great on my bottom ground," says Mathis.

Hail adjuster Lynn Brandt (see accompanying photo) works for Rain & Hail Insurance Company. The photo was taken June 30 as Brandt was checking the south end of one of the Mathis corn fields which had some hail damage. "That cornfield was planted May 9," says Chip Mathis. "It had already grown quite tall by the end of June and still looks great, especially where the hail didn't hit it. I put Lynn in the picture to show just how tall this corn was on June 30."

Iowa corn crop rated 82% "good to excellent" in latest weekly survey

About 82% of Iowa's 2011 corn crop is now in the "good to excellent" category, according to the weekly survey released July 5 by USDA's National Ag Statistics Service. The data was gathered from crop reporters statewide on June 3 and analyzed and released by the Iowa Office of USDA/NASS in Des Moines.

The warm, dry weather for the week ending July 3 was good for crop development and very welcome after several weeks of cool, wet weather had slowed crop progress.

"Specifically, the corn condition for Iowa for the week ending July 3 is rated at 1% very poor, 2% poor, 15% fair, 54% good and 28% excellent," notes Greg Thessen, director of the Iowa NASS office.
