1 A Wisconsin Corn Hybrid Performance Trial Results Grain and Silage Department of Agronomy College of Agricultural and Life Sciences University of Wisconsin Wisconsin Crop Improvement Association

2 December 2007 A WISCONSIN CORN HYBRID PERFORMANCE TRIALS GRAIN AND SILAGE Joe Lauer, Kent Kohn, and Thierno Diallo The University of Wisconsin Extension-Madison and College of Agricultural and Life Sciences conduct a corn evaluation program, in cooperation with the Wisconsin Crop Improvement Association. The purpose of this program is to provide unbiased performance comparisons of hybrid seed corn available in Wisconsin. These trials evaluate corn hybrids for both grain and silage production performance. In 2007, grain and silage performance trials were planted at fifteen locations in four production zones. Both seed companies and university researchers submitted hybrids. Companies with hybrids included in the 2007 trials are listed in Table 1. Specific hybrids and where they were tested are shown in Table 2. In the back of the report, hybrids previously tested over the past three years are listed (Table 25). At most locations trials were divided into early and late maturity trials, based on the hybrid Relative Maturities provided by the companies. The specific Relative Maturities separating early and late trials are listed below. GROWING CONDITIONS FOR 2007 Seasonal precipitation and temperature at the trial sites are shown in Table 4. Spring planting conditions were good resulting in early planting. Air temperatures were variable while precipitation was drier than normal. Accumulation of growing degree units for the entire season was normal. In July, drought stress was evident on corn plants in central and northwest Wisconsin. Drought conditions affected hybrid trial performance at Chippewa Falls and Spooner. Widespread rains occurred by mid-august, too late for normal pollination in many area. Record rainfall was recorded in August and September with flooding occurring in southwest Wisconsin. Insect pressure was not significant. Anthracnose was observed on corn in southern Wisconsin causing numerous broken tops and some standability problems. A frost occurred September 14 and a killing frost occurred in late-october. Yields in the UW hybrid trials were average to above average at most sites. CULTURAL PRACTICES The seedbed at each location was prepared by either conventional or conservation tillage methods. Seed treatments of hybrids entered into the trials are described in Table 3. Fertilizer was applied as indicated by soil tests. Herbicides were applied for weed control and supplemented with cultivation when necessary. Corn rootworm insecticide was applied when the previous crop was corn. Information for each location is summarized in Table 5. PLANTING A corn planter with cone units was used at all locations. Two-row plots were planted at all locations. Twenty-five foot long plots were over planted and hand thinned to achieve as near a uniform stand as possible. Each hybrid was grown in at least three separate plots (replicates) at each location to account for field variability. HARVESTING Grain: Two-row plots were harvested with a self-propelled corn combine. Lodged plants and/or broken stalks were counted, plot grain weights and moisture contents were measured and yields were calculated and adjusted to 15.5% moisture. Test weight was measured on each plot. Silage: Whole-plant (silage) plots were harvested using a tractor driven, three-point mounted one-row chopper. One row was analyzed for whole plant yield and quality. Plot weight and moisture content were measured, and yields were adjusted to tons dry matter / acre. A sub-sample was collected and analyzed using near infra-red spectroscopy. 1

Within each trial, hybrids are ranked by moisture, averaged over all 2007 trials conducted in that zone. Yield and moisture data for both 2006 and 2007 are provided if the hybrid was entered previously in the 2006 trials. A two-year average for yield is calculated using location means as replications. A hybrid index in Table 2 lists relative maturity ratings, specialty traits, seed treatments and production zones tested for each hybrid. RELATIVE MATURITY Seed companies use different methods and standards to classify or rate the maturity of corn hybrids. To provide corn producers a standard maturity comparison for the hybrids evaluated, the average grain moisture of all hybrids rated by the company relative maturity rating system are shown in each table. Company relative maturity ratings are rounded to 5-day increments. The Wisconsin Relative Maturity rating system for grain and silage (GRM and SRM) categorizes corn hybrids into relative maturity groups by comparing harvest grain or silage moisture of a hybrid to the average moisture of hybrids rated by companies for each group. In these Wisconsin results tbles, hybrids with lower moisture than a particular relative maturity average are likely to be earlier than that relative maturity, while those with higher grain moisture are most likely later in relative maturity. Maturity ratings can be found in Table 2. The Wisconsin ratings (GRM and SRM) are grain or silage moisture at harvest compared to company maturity ratings. Each hybrid in a trial is rated and averaged over all trials in a zone. 2

4 GRAIN PERFORMANCE INDEX Three factors yield, moisture, and standability are of primary importance in evaluating and selecting corn hybrids. A performance index (P.I.), which combines these factors in one number, was calculated for multi-location averages for grain trials. This performance index evaluates yield, moisture, and lodged stalks at a 50 (yield): 35 (moisture): 15 (lodged stalks) ratio. The performance index was computed by converting the yield, dry matter, and upright stalk values of each hybrid to a percentage of the test average. Then the performance index for each hybrid that appears in the tables was calculated as follows: Performance Index (P.I.) = [(Yield x 0.50) + (Dry matter x 0.35) + (Upright stalks x 0.15)] / 100 SILAGE PERFORMANCE INDEX Corn silage quality was analyzed using near infra-red spectroscopy equations derived from previous work. Plot samples were dried, ground, and analyzed for crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), in vitro cell wall digestibility (NDFD), in vitro digestibility (IVD), and starch. Spectral groups and outliers were checked using wet chemistry analysis. The MILK2006 silage performance indices, milk per ton and milk per acre, were calculated using an adaptation by Randy Shaver (UW- Madison Dairy Science Department) of the MILK91 model (Undersander, Howard and Shaver; Journal Production Agriculture 6: ). In MILK2006, the energy content of corn silage was estimated using a modification of a published summative energy equation (Weiss and coworkers, 1992; Animal Feed Science Technology 39:95-110). In the modified summative equation, CP, fat, NDF, starch, and sugar plus organic acid fractions were included along with their corresponding totaltract digestibility coefficients for estimating the energy content of corn silage. Whole-plant dry matter content was normalized to 35% for all hybrids. The sample lab measure of NDFD was used for the NDF digestibility coefficient. Digestibility coefficients used for the CP, fat, and sugar plus organic acid fractions were constants. Dry matter intake was estimated using NDF and NDFD content assuming a 1350 lb. cow consuming a 30% NDF diet. Using National Research Council (NRC, 2001) energy requirements, the intake of energy from corn silage was converted to expected milk per ton. Milk per acre was calculated using milk per ton and dry matter yield per acre estimates. LEAST SIGNIFICANT DIFFERENCE Variations in yield and other characteristics occur because of variations in soil and other growing conditions that lower the precision of the results. Statistical analysis makes it possible to determine, with known probabilities of error, whether a difference is real or whether it might have occurred by chance. Use the appropriate LSD (least significant difference) value at the bottom of the tables to determine true differences. Least significant differences (LSD s) at the 10% level of probability are shown. Where the difference between two selected hybrids within a column is equal to or greater than the LSD value at the bottom of the column, you can be sure in nine out of ten chances that there is a real difference between the two hybrid averages. If the difference is less than the LSD value, the difference may still be real, but the experiment has produced no evidence of real differences. Hybrids that were not significantly lower in performance than the highest hybrid in a particular test are indicated with an asterisk. HOW TO USE THESE RESULTS TO SELECT TOP-PERFORMING HYBRIDS The results can be used to provide producers with an independent, objective evaluation of performance of unfamiliar hybrids, promoted by seed company sales representatives, compared to competitive hybrids. Below are suggested steps to follow for selecting top-performing hybrids for next year using these trial results: 1. Use multi-location average data in shaded areas. Consider single location results with extreme caution. 2. Begin with trials in the zone(s) nearest you. 3. Compare hybrids with similar maturities within a trial. You will need to divide most trials into at least two and sometimes three groups with similar average harvest moisture within about 2% range in moisture. 3

5 4. Make a list of 5 to 10 hybrids with highest 2007 Performance Index within each maturity group within a trial. 5. Evaluate consistency of performance of the hybrids on your list over years and other zones. a. Scan 2006 results. Be wary of any hybrids on your list that had a 2006 Performance Index of 100 or lower. Choose two or three of the remaining hybrids that have relatively high Performance Indexes for both 2006 and b. Check to see if the hybrids you have chosen were entered in other zones. (For example, some hybrids entered in the Southern Zone Trials, Tables 4 and 5, are also entered in the South Central Zone Trials, Tables 6 and 7). c. Be wary of any hybrids with a Performance Index of 100 or lower for 2006 or 2007 in any other zones. 6. Repeat this procedure with about three maturity groups to select top-performing hybrids with a range in maturity, to spread weather risks and harvest time. 7. Observe relative performance of the hybrids you have chosen based on these trial results in several other reliable, unbiased trials and be wary of any with inconsistent performance. 8. You might consider including the hybrids you have chosen in your own test plot, primarily to evaluate the way hybrids stand after maturity, dry-down rate, grain quality, or ease of combine-shelling or picking. 9. Remember that you don t know what weather conditions (rainfall, temperature) will be like next year. Therefore, the most reliable way to choose hybrids with greatest chance to perform best next year on your farm is to consider performance in 2006 and 2007 over a wide range of locations and climatic conditions.
