Interested in testing new practices and comparing how they perform against other fields? Looking to break yield barriers and push pods to their full potential?

The ISA Yield Challenge is the opportunity to experiment with on-farm trials, discover what works best on your soil and compete with your peers in Illinois, all for a chance at cash rewards and bragging rights come harvest.


100-Bushel Challenge

Growers compete in irrigated and non-irrigated categories state-wide. The grower who achieves the largest yield over 100 bushels per ace in each category takes home a $4,000 prize.

Crop Region Contest

Growers compete within their regions for the top yield. First place in each region receives $1000.

Double-Crop Competition

Growers who double-crop soybeans after wheat or another crop harvested that same season can now submit a yield entry. There are three districts in this category: district 1 is north of I-80, district 2 is I-80 to I-70, and district 3 is south of I-70. First place in each district receives $1,000. 

Side-by-Side Region Contest

Growers compare standard practices (control plot) with improved practices (test plot). The grower with the highest percentage yield increase in their region receives $1000.


Who can enter?

Growers can enter the Yield Challenge on their own or with a sponsor. Promoters can include agronomists, ag retailers, distributors or manufacturers. Promoters often recruit growers to test either a single product or combination of products. We encourage growers to reach out to agronomists and crop advisers to try new practices.

Students Are Welcome to Compete

The Yield Challenge provides a great opportunity for students to gain hands-on experience in innovative and effective crop production techniques. We encourage FFA chapters, 4-H clubs and college ag clubs to participate. They may register in their appropriate crop region or district(double-crop) competition.
