1 2005 SHOWPLOT RESULTS Unbiased Results from On-Farm Tests 3801 S. Western Ave., Suite 100 Sioux Falls, SD (605) Fax (605)

2 Dear Grower: The (SDCGA) is pleased to provide you with the results from its 2005 Showplot Program. Fifteen producers planted plots, 9 of which were Roundup Ready corn and 6 were conventional corn showplots. Producers compared various corn hybrids side by side under growing conditions unique to their areas of the state. Yields ranged from an average of 2 bushels an acre up to the reported high of 215 bushels an acre. One plot was not harvested. As usual, weather conditions played a big role in corn yields. Most regions experienced warmer than normal temperatures throughout the growing season, which ultimately lead to corn maturing early and moistures low at harvest. Most corn growing areas of the state had a wet spring. Following the wet spring some areas turned dry while other regions of the state received plenty of moisture through out the growing season. We thank the cooperators and the corn industry for their participation in this valuable program. SDCGA provided information to all of its members on genetically enhanced corn, encouraging them to Know Before You Grow in the spring and make hybrid selections that would be readily marketable in their area at harvest. SDCGA is a grassroots membership organization and we thank everyone who helped make the Showplot program a success. Our goal is to provide fair, accurate and unbiased information to the state s corn producers. We re able to do that because of the help and support of all the seed companies and representatives, the SDCGA board of directors and other Ag industry representatives. Thank you for your interest and participation in the SDCGA. Sincerely, Chad Blindauer Showplot Committee Chairman Printed on recycled paper.

3 Your SDCGA membership is working hard for you! Legislatively: The SDCGA is your representation in Washington, D.C. and Pierre, S.D. The SDCGA has worked hard on issues that benefit South Dakota producers such as the energy bill, the disaster bill, the State Producer Incentive and the Farm Bill. The SDCGA is in touch with state and national legislators on producers behalf to urge action on legislation. Hold Ethanol Day at the S.D. Legislature and network with state representatives. Education: Risk Management Seminars were offered in three South Dakota locations including Pierre, Huron, and Brookings in 2005 Business Planning workshops provide producers with the in-depth tools to manage and direct their operations. Computer technology training leads producers through profit-generating techniques found on the internet or computer programs. Yellow Dime promotions are sponsored all over South Dakota countless times during the year, which demonstrate the impact of the industry on local communities. Access to research-based information on growing and planting crops. Membership: Membership gets special invitations and rates to SDCGA events such as Annual Meeting, Value Added Day at the State Fair, Corn Cob Open Golf Tournament, Risk Management Seminars, Business Planning Workshop and other activities that take place with SDCGA. Discounts on products and events. Incentive for 3-year memberships such as seed certificates and free ethanol. 1

4 The Numbers Behind The Numbers Just about all the data we publish is pretty straight-forward, self-explanatory, and of a format common to the seed industry. One practice we employ which is often disputed is the use of a common Tester hybrid at a fixed everyother, third, or fourth entry in each of our plots. The function of the Tester is to first reveal and secondly to adjust for variability of the ground (soil) found at any of our plot locations. Since the Tester serves only to help in analyzing the plot results, there is no good reason to reveal the identity of the hybrid; and several valid reasons not to. Since this practice is disputed, we publish raw as well as adjusted data for each entry and leave it to you to use whichever you feel more comfortable with. The only variable subjected to the adjustment procedure is yield. Our justification for using the tester/adjustment method: We know that every location used for a plot site induces variability (error) of performance that is due to the heterogeneity of the site (ground or soil) itself and not due to differences of the hybrids being tested. Using the adjustment method is an attempt to account for (remove) as much of that variability as possible. Other research entities (Univ. of MN among others) dispute how well this method actually works. Considering the rationale of opposing arguments, this is our position and current belief: 1)The tester adjustment method (TAM) serves reasonably well in removing variability that exists on a side-to-side gradient. (It is interesting to note that in small plot research the very design of employing the use of ranges and replications is done so in attempt to minimize or adjust for the gradient source of error.) 2)The TAM does not attempt to remove variability that is random; in fact, the TAM may actually serve to amplify this source of variability (noise). (Small plot research uses randomization and replications to manage random variability.) 3)Research organizations select sites on which to perform testing primarily for their uniformity (lack of gradient variability; random variability will still be present) the TAM method would not work well at such sites. 4)Farmer fields in which we do testing almost without exception do contain strong gradient components and here the TAM serves its purpose reasonably well. Yet there are still limitations. These assumptions are made when using the TAM: 1)Tested hybrids will vary in the same direction and degree as does the Tester in response to changing edaphic (soil) factors. 2)Tester strips always get planted on the peaks and valleys of any reversals in productivity trends as caused by soil factors. 3)Changes in soil productivity between Tester strips occurs linearly. We know that these assumptions are rarely if ever completely met; but attempting to account for gradient variability and being successful in part is still better than ignoring it all-together. The Method: First the tester average is calculated. Secondly the yields of tested hybrids (entries) are expressed relative to the yields of the bracketing Tester strips as a percentage. (When the Tester frequency is every-other, each of the 2 bracketing Testers is weighted equally; with a Tester frequency of every third, the nearby Tester is weighted 2/3 and the far Tester is weighted 1/3; when the Tester frequency is every fourth strip, the nearby Tester is weight _ and the far Tester is weighted _, for the middle tested entry in a set between Testers the 2 Testers are weighted equally.) And finally, the Tester Average is multiplied by the relative performance of each entry ( % of Tester ) to produce the Adjusted Yield. Ranking: One last note should be made in regard to our Ranked column: It refers to how each entry ranked in Adjusted Gross Income per acre (using the adjusted yields). 2

5 Know Before You Grow You should select hybrids with the full knowledge of whether it is conventional, fully approved for EU export or not yet fully approved for EU export. Growers should read their grower agreements before planting and be aware of the requirements of those agreements. The EU recently announced that a number of hybrids are approved as processed feeds (corn gluten feed and DDGS); these changes are reflected in the Approval Status of Biotech Corn Hybrids Table. Even with these changes, if you are planting hybrids awaiting full EU approval you must talk with your grain handler. SDCGA remains committed to the principle that U.S.-grown biotech hybrids yet to be approved in major export markets should not be placed into export channels.

PLEASE NOTE: The Know Before You Grow database is generated by distributing surveys to seed companies throughout the country. Its accuracy relies on accurate reporting from the companies that return these surveys. While SDCGA strives to make the information as comprehensive and factual as possible, it is absolutely necessary that growers work with seed distributors and grain buyers to verify that the seed they purchase is appropriate for the market that they wish to serve. For more information contact your local seed company representative. Know Where to Go SDCGA urges you to funnel hybrids not fully approved for EU export into one of three markets. Those markets are: (1) your own livestock rations, (2) domestic livestock feeding channels or (3) elevators accepting grain not yet fully approved for EU export. Visit the American Seed Trade Association Web site for more information about the policies of grain facilities accepting hybrids not yet approved for export to the EU. Last Reviewed on 10/24/2005 4
