Teams of Purdue University students took the top two spots in the competition, sponsored by the Indiana Soybean Alliance and the Indiana Corn Marketing Council, the school reported Thursday.
Both teams received a $20,000 prize for their work in the contest intended to help students be innovative entrepreneurs with corn and soybeans.
The awards were announced Wednesday in Indianapolis.
"Indiana soybean and corn farmers continue to fund these competitions at Purdue because they believe that encouraging students to think about corn and soybeans in new ways benefits our state's soybean and corn industries in a multitude of ways," Jane Ade Stevens, executive director for both organizations, said. "We are excited to see that interest in these competitions continues to be strong and that we continue to attract students from across the university who use their creativity and knowledge to bring us a high caliber of products."
