2 PREFACE Our motto is We test the best and that is exactly what we do. Each year, the best seed companies and organizations select several of their best hybrids for evaluation by the MU Variety Testing Program. We use the latest scientific principles and procedures to provide farmers and others with an interest in corn hybrid performance with accurate and unbiased information. We respect the seed companies and organizations that put their hybrids to the test. We are honored that they entrust us with their valuable products. It takes courage to allow their hybrids to be compared with all of the others. Not every company participates in our program for various reasons. Those companies that do participate deserve your consideration when purchasing seed for the next growing season. Please view the table at the back of our book for names and addresses of participating seed companies. Thank them for their courage and tell them you saw their hybrid in our program. The MU Variety Testing Program has provided Missouri farmers with unbiased variety comparisons for more than 75 years, first with corn, then soybean and wheat. Current staff members have a total of over 100 years of experience with testing crop yield performance. Our plots are placed where you farm. They have the soils and weather conditions your fields have. The MU Variety Testing Program is on-farm research in the truest sense of the word. Fourteen of our locations are on farmer fields in your communities. The other four locations are MU farms. These CAFNR owned and operated research centers sample the north, central and southeast regions of Missouri and combined with the private farm locations provide you with the diversity of environments you need to select the best hybrids for your farm. View the map in our procedures section to see the placement of our locations and the cooperators that are so important to the quality of our information. Evaluating yield and making decisions based on that evaluation are difficult because yield is highly affected by environment even the small differences that exist across a field. We use replication, plot size, and plot placement to minimize the noise. Please read the procedures section of this book to better understand what we do and the tools we provide you to make hybrid selection decisions. Our data tables are arranged to help you quickly see how hybrids compare. We strongly suggest that you use information from more than one location. Our tables of region means provide you comparisons across multiple locations. Although yield is extremely important please see our hybrid characteristics table located near the back of the book to view additional information that you might find helpful during hybrid selection. Thank you for your interest and support. Please support the companies that participate in our program. If you have suggestions on how we can improve our program please contact me directly (wieboldw@missouri.edu; ). The MU Variety Testing Program exists to serve your needs. We want to provide you with the best information possible. William Bill Wiebold

3 PROCEDURES Regions and Locations The MU Variety Testing Program divides the corn growing area of Missouri into four regions: North, Central, Southeast, and Southwest. Each region contains two to five locations, depending on the or tests tests conducted in a region. The same hybrids are tested in all locations of a test within a region. Locations for 2013 are as follows: 1. Craig (Holt County); Steve Cunningham Farm 2. Albany (Gentry County); Hundley-Whaley Center 3. Mooresville (Livingston County); Beetsma Farm 4. Novelty (Knox County); Greenley Research Center 5. LaGrange (Lewis County); Roger Tiemann Farm 6. Henrietta (Ray County); John Williams Farm 7. Marshall (Saline County); Frank, Al, & Stan Swisher Farm 8. Columbia (Boone County); Bradford Research Center 9. Laddonia (Audrain County); Kevin Freyer Farm 10. Truxton (Montgomery County) Roy Cope Farm 11. Annada (Pike County); Bob Burkemper Farm 12. Harrisonville (Cass County); Doug Roth Farm 13. Adrian (Bates County); Darrel Tenholder Farm 14. Urich (Henry County); Kurt Gretzinger Farm 15. Lamar (Vernon County); Ron Bean Farm 16. Oran (Scott County); Glenn Nothdurft Farm 17. Charleston (Mississippi County); H.S. Byrd Farm 18. Portageville Loam (Pemiscot County); Delta Research Center 18. Portageville Clay (Pemiscot County); Delta Research Center 15 Entries All seed companies were eligible to enter hybrids in the 2013 corn tests. Participation was voluntary and the MU Variety Testing Program exercised no control over which, or how many hybrids, were entered. The MU Variety Testing Program receives no Missouri tax dollars, so a fee was collected for each entry to fund the program Test Descriptions Non-Irrigated Corn Test consists of five locations in the North region, five locations in the Central region, and three locations in the Southwest region. Plots were not irrigated in this test. Irrigated Corn Test consists of two locations in the Central region, three locations in the Southwest region, and four locations in the Southeast region. Plots were irrigated as weather conditions warranted. Field Plot Design and Plot Management Hybrids were randomly arranged in the field according to a lattice design with three replications. At all locations, plots were four rows wide (10 feet) and 27 feet long. The center two rows were harvested to determine yield. All tests were planted and harvested with commercial equipment modified for small plot work. Row spacing for all corn tests was 30 inches. Planting rates were 30,000 kernels/acre for the Non- Irrigated Corn Test and 36,000 seeds/acre for the Irrigated Corn Test. Fertilizer was applied at each site at the discretion of the farmer or the research station manager. Herbicides were used to control weeds, and additional hand weeding was performed as required. An in-

4 furrow insecticide was applied at all locations. Management details varied among locations and are specified in individual regional crop management summaries. Data Recorded Plant stands were recorded mid-season. Lodging was rated immediately before harvest using a scale of 1 to 5 where 1 = less than 20% plants lodged, 3 = all plants leaning moderately or 40% to 60% lodged, and 5 = 80% or more plants lodged. During harvest, plot grain weights were measured and an electronic moisture tester was used to determine the moisture content of the grain. Yields were corrected to a moisture content of 15.5% and expressed as bushels/acre. Comparing Hybrids The performance of a hybrid cannot be measured with absolute precision. Uncontrolled variability is involved in the determination of each plot s yield. This variability exists in all field experiments and in farmer fields. Statistics are used to account for this variability and to assist farmers in selecting superior hybrids. The statistical tool used by the MU Variety Testing Program is called least significant difference (LSD). The LSD is simple to use. When two hybrids are compared and the difference between them is greater than the LSD, the entries are considered to be significantly different. Differences between two hybrids that are smaller than the LSD may have occurred by chance and are considered to be not significant. In other words, the two hybrids might have the same yield, grain moisture or other characteristics of interest. The LSD can be found at the bottom of each table. The MU Variety Testing Program arranges hybrids within each table from highest yield to lowest yield. The "top yielding" hybrid in each test is identified by a double asterisk (**) placed next to its yield. Hybrids that did not yield significantly less than the highest yielding hybrid in the test are denoted in the tables by a single asterisk (*). Thus, by reading down the yield column, readers can readily identify the highest yielding hybrids in a test. Hybrid performance may seem inconsistent from location to location and from year to year. These differences are caused by differences among environments for rainfall, temperatures, soil fertility, diseases, insects, and many other factors. To obtain an improved estimate of relative hybrid performance, readers should consider results from more than one environment (locations and/or years). The vast majority of hybrids are entered into our tests for only one year, so comparing hybrids across multiple locations becomes even more important. The MU Variety Testing Program facilitates hybrid comparisons across locations by publishing Region Means. Region Means tables contain yield data from all individual locations in the region with yields averaged across the locations. The hybrid with the highest average yield and hybrids that do not differ for yield from that hybrid are designated with double (**) and single (*) asterisks. Although yield usually receives first consideration, other agronomic characteristics may be important when selecting a corn hybrid. Stalk strength, maturity, and resistance to insects and diseases are among the hybrid characteristics that deserve careful consideration. We provide a table that contains several important characteristics of hybrids entered into the MU Variety Testing Program. This information was provided by seed companies. Please contact seed company representatives for the latest information. Seed entered into the MU Variety Testing Program is usually treated with one or more seed treatments. These seed treatments are identified in the table listing the hybrid characteristics. Accessibility of Data Results of the 2013 crop performance tests are available in print format and online at varietytesting.missouri.edu.
