U.S. Testing Network
Yield trial results for non-GMO and organic corn hybrids
An estimated 80 percent of the corn grown in the U.S. today is genetically modified and most seed companies continue to phase out non-GMO corn seed varieties. Together with breeders and seed retailers, Practical Farmers of Iowa launched the U.S. Testing Network (USTN) in 2009 to rebuild the dwindling selection of non-GMO and organic seed corn.
Practical Farmers of Iowa coordinates the yield trials for non-GMO and organic corn hybrids and now offers public data from the tests for farmer fact-based decision-making.
