Thank You to All Field Day Attendees:
Our field day on September 7 th turned out well. We were delighted to welcome old friends and new people interested in what we do. There was a lot of interaction with questions and answers. For those who couldn’t make it, we can recap a few highlights.
Agronomic Practices to Maximize Corn Yields
- Hybrid selection
- Yield potential (most important)
- Crop rotation (used mostly corn following beans)
- Plant population (32M-38M most common)
- Row width (30 inch for the majority (78%) of farmers)
- Planting dates varied by region (in the central corn belt mid April to early May)
- Nitrogen application (1.0 lb/bushel of grain harvested and 0.5 lbs/bushel for stover produced)
- Nitrogen application applied as closely as possible to crop uptake (most contestants had in season nitrogen application either as side dressing or at the times of irrigation)
US Testing Network (USTN)
This is organized and managed by the Practical Farmers of Iowa. The network provides a yield test program that allows non-GMO and organic corn breeders, and seed marketers to test corn hybrids in a network of testing locations within the appropriate maturity zones. The network covers the relative maturities RM 95 to RM 115. Information about this network is available in the Practical Farmers of Iowa website.
Non-GMO Purity for Conventional & Organic Corn
- Genetic purity of the inbred parents used for the production of non-GMO and organic corn hybrids
- The seed production practices that are used to insure that there is no adventitious pollen contaminations
- The appropriate use of the seed by grain producers to take advantage of the seed purity standards used.

GEI Specialty Corn Used for Meal
A highlight from our Field Day was the individual cornmeal pizzas that were served to showcase some uses for our nutrient-rich hybrids. The cornmeal came from our high carotene hybrid (GEI 2318) milled by Early Morning Harvest in Panora, Iowa. Blue corn tortillas (GEI 411C) from Papa’s Blue Cornmeal (sold through Amazon) were the base for refried beans, queso fresco and smoked brisket or smoked pulled chicken. High lysine cornmeal cookies were made from our GEI 101 lys, grown and milled by Whole Grain Milling Co. in Welcome, Minnesota.
