Posted 19 March 2010. Crop Management. Corn and Soybean Seed Selection for 2010 Source: University of Illinois Press Release. aces.illinois.edu Urbana-Champaign, Illinois (March 2, 2010)--Northern Illinois farmers will soon be selecting corn and soybean seed for 2010. Seed selection is a critical aspect of planning for the upcoming growing season. University of Illinois Extension can help farmers make those important seed selection decisions.
For many years, University of Illinois Department of Crop Sciences has conducted corn and soybean performance trials across the state. Results of the 2009 trials are available at this website vt.cropsci.illinois.edu and in booklets titled Corn Hybrid Test Results in Illinois-2009 and Soybean Variety Test Results in Illinois-2009. These booklets should be available soon at local Extension offices. In 2009, corn and soybean trials were conducted at 12 and 13 locations, respectively, across Illinois. Trials were conducted on a regional basis to represent major soil and climatic areas of Illinois. The northern region had both corn and soybean trials at DeKalb, Erie, and Mt. Morris. The average corn yield and moisture content for the northern region was 223 bushels per acre and 28.8 percent. The regional average for maturity group 2 Roundup Resistant soybean was 60.8 bushels per acre. In addition to yield and moisture content, corn trials included percent erect plants and if appropriate, insecticide seed treatment, and genetic traits(s). Non-GMO hybrids were included in the tests. Oil, protein, starch, and extractable starch were reported for hybrids at the DeKalb location. The DeKalb site also included a corn following corn trial that consisted of 39 hybrids averaging 173 bushels per acre and 36.6 percent moisture. In the soybean trials in addition to yield, results included maturity date, lodging score, plant height, and if appropriate insecticide and/or fungicide seed treatment. Conventional varieties were also included. Protein and oil content were reported for varieties at the Erie site. Since hybrids and varieties were replicated three times at each site, entries can be compared to see if a statistical difference exists between them. Results of replicated tests, like the University of Illinois corn and soybean performance trials, are more reliable than those of single-year or single-strip tests.
