Producing modern seed corn takes patience

Take a behind-the-scenes look at why producing popular hybrids is a labor of love.

Do you have what it takes to be a hybrid seed corn producer? Here’s a glimpse at what one seed producer has experienced so far this season:

  • Hail destroyed production fields for a key hybrid in mid-June. Because the hybrid is sought after but it was too wet to replant there in time, soybeans growing for seed at another location where it wasn’t wet were terminated so the inbred parents for the hybrid could be planted there instead.

  • A freak windstorm in mid-July wiped out a highly desirable production field — too late to pivot to another field this time. So, while the producer will have plenty of seed, that particular hybrid will be in limited supply.

Still think you want to be a seed producer? Obviously, it takes a different mindset.

“We must think differently than a normal corn grower, no doubt about it,” says Darin Lucas, a field production manager for Beck’s at the company’s Atlanta, Ind., location. “We start out the season with a plan, and we know the steps it takes to produce even hard-to-grow hybrids, but we also have to be flexible enough to shift on the go to a modified plan.”

Wet, rainy stretches in May meant that seed corn planting, like regular corn planting, was delayed. This is a particular challenge in production fields where the male inbred must be planted after the female and timed correctly.

“For some inbreds that aren’t strong pollinators, we plant a male row, then come back and plant the male again in the same row a few days apart,” Lucas explains. “That helps spread out pollination and gives more days of pollen available to find silks of the female inbred. But we only have a narrow window to make that second planting pass.”

Tough summer for seed growers

Here are more challenges seed producers like Lucas faced this year:

Wet soils at detasseling time. “We must get female rows detasseled before tassels can emerge and spread pollen,” Lucas says. Sometimes that means running their cutting machines with custom-designed cutting heads to even up the field when soils are still wet, tracking up fields as they go. Then a couple of days later, the same machines equipped with pulling devices this time must go through the field, pulling tassels.

“We get 85% to 90% of the tassels removed on female rows through that process,” Lucas says. To remove the remaining tassels that escape mechanical removal, crews of H-2A workers meticulously comb fields, taking out remaining tassels.

Aphids. Corn aphid numbers appear to be up across the Midwest this year. If you are a commercial corn grower, it might be more of an annoyance than a yield threat. If you are a seed producer, it’s a risk you can’t take.

“Aphids like to feed on tassels as they begin to emerge on male rows,” Lucas explains. “Left unchecked, they can produce a sticky substance and gum up tassels, interfering with pollen shed. In years like this one, we spray for them so that we don’t risk interfering with pollination.”

Tom J. Bechman became the Midwest Crops editor at Farm Progress in 2024 after serving as editor of Indiana Prairie Farmer for 23 years. He joined Farm Progress in 1981 as a field editor, first writing stories to help farmers adjust to a difficult harvest after a tough weather year. His goal today is the same — writing stories that help farmers adjust to a changing environment in a profitable manner.

Bechman knows about Indiana agriculture because he grew up on a small dairy farm and worked with young farmers as a vocational agriculture teacher and FFA advisor before joining Farm Progress. He works closely with Purdue University specialists, Indiana Farm Bureau and commodity groups to cover cutting-edge issues affecting farmers. He specializes in writing crop stories with a focus on obtaining the highest and most economical yields possible.

Tom and his wife, Carla, have four children: Allison, Ashley, Daniel and Kayla, plus eight grandchildren. They raise produce for the food pantry and house 4-H animals for the grandkids on their small acreage near Franklin, Ind.
