There were some disease issues and wild weather throughout the soybean growing season, but Iowa Crop Improvement Association Executive Director Jim Rouse said the biggest pressure this year came on those harvesting the crop.
“I don’t think it was a stress on the tests as much as on the crew,” Rouse said. “There was a 10- or 12-day period where we just sat and watched everything get wet. It really makes you wonder if there is anything worth harvesting. We really only got one (soybean) field out before the rain delay and the rest of them all came out in about a 10-day period.”
The yields in general showed the same average spread as they have in the past several years, he said.
When all was said and done, the crews lucked out and didn’t have to toss any test plots. Rouse said some came close, but “we could make sense out of the bad ones enough to publish it.”
He said the worst locations for the bean fields ICIA tested were in north central Iowa and south central Iowa, where they had opposite problems. North central was too wet, whereas south central dealt with a drought much of the summer.
While the crews were able to get the crop out of the ground despite some of the volatile weather, Rouse said there was also more disease than in previous years.
He also noted that for these tests, conventional seeds aren’t as common for soybeans.
“We have a lot fewer conventionals than corn,” Rouse said. “In soybeans, conventionals make up a tiny portion, and the rest are LibertyLink, Roundup Ready 2 Yield and Roundup Ready 2 Extend.
