The Indiana Corn Growers Association Board of volunteer farmer Directors is proposing a modernization to the Corn Market Development Law (IC 15-15-12) for the 2027 Indiana legislative session. Among other minor changes, this update will include broader grower accessibility to Board elections and an assessment rate adjustment to keep up with inflationary pressures and other Midwest states.
The rate hasn’t changed since 2007. Inflation over the past 19 years has steadily eroded market development value, limiting investments in key areas like disease research and trade partnerships. The pressures of South American competition, rising on-farm sustainability requirements, lower commodity prices and disease make it even more important.
What does this mean for farmers?
The proposed rate will change from one half of one cent to one cent per bushel. This change would not remove a farmer’s right to a refund.

“Every dollar invested in the market development program is put to work for farmers—whether it’s through research, market access, or new uses for corn. It’s about making sure our industry remains strong and profitable for the next generation.”

“As a volunteer director of the Indiana Corn Marketing Council and a fellow farmer, I want to continue making the most of every dollar. There is always more work to do in supporting market development, funding critical research, or enhancing educational opportunities. I am supportive of efforts made by ICGA to do more to deliver strong returns on my investment.”

“The corn market development program isn’t some distant program—it’s led by farmers, for farmers. As a board member, I take my role seriously in making sure these dollars are invested wisely to generate real returns for Indiana growers.”
What are some Indiana market development successes?
- Since 2007, ethanol production has grown to use 470 million bushels per year – a critical market for corn. About 400 pumps offering higher blends of ethanol have been installed.
- Indiana corn market development has invested in critical research to combat dozens of diseases, weeds, and pests that challenge our farms—like Mycotoxins and Tar Spot. ICMC made possible the Purdue Corn and Soybean Innovation Center in West Lafayette, where critical research is being conducted.
- In 2025, ICMC engaged directly with over 600,000 consumers about corn through its outreach and education programs.
- In 2025 alone, ICMC hosted nine trade teams representing 24 countries and directly engaged with promotion activities with international markets in 21 countries.

How does Indiana’s assessment rate compare to other states?
Indiana’s market development budget falls short compared to other states. Indiana is the 5th largest producer of corn, yet is 8th in total ICMC budget.
