Southeast Research and Demonstration Farm
The Iowa Crop Performance Test—Soybeans is conducted each year to provide information farmers need to select the best varieties or brands for their production conditions. Seed companies, Iowa farmers, and the Iowa Crop Improvement Association may include entries in these tests. The experiments grown in 2005 at the Southeast Research Farm were planted May 11 and harvested October 5. One test evaluated 16 lines of soybeans treated with conventional herbicide and another test evaluated 75 lines of Roundup® Ready (RR) beans.
