1 AGRICULTURAL EXPERIMENT STATION UNIVERSITY OF KENTUCKY COLLEGE OF AGRICULTURE, LEXINGTON, KY, PR Kentucky Hybrid Corn Performance Test William L. Pearce, Ron W. Curd, and Chad Lee, Department of Plant and Soil Sciences The objective of the Kentucky Hybrid Corn Performance Test is to provide performance estimates of hybrid seed corn sold in Kentucky. The test has been conducted in an unbiased manner according to accepted agronomic practices. Presentation of Data Complete 2011 data is presented for the tests across all locations and tests at each location. Two-and three-year averages for yield are included in each of the single location tables. Tables that include data over multiple years and/or from multiple locations provide a better indication of hybrid performance. The multiple location tables are listed on page 1. If individual location data is used it should be in combination with a multiple location average. These tables present better estimates of hybrid yield ability than data gathered at one location in one year. Comparisons between yields and other characteristics of any two or more hybrids should be made only with data from one table at a time. Hybrids are grouped into Early, Medium, Late, and White tests based on relative maturity or trait characteristics. Hybrids that are likely to yield as high as the highest yielding hybrid, based on statistical evaluation, are indicated by asterisks. See Hybrid Comparisons and Experimental Design and Mean Comparisons sections for more detail. Testing Procedure Selection of Hybrids The hybrids chosen for testing are those most likely to be available for sale in Seed of each commercial hybrid (Table 2) was obtained from the sponsoring company. Each company defined the maturity of their hybrids and was given the opportunity to identify the proper tests for their hybrids. Location of Tests The map on page 1 shows the test locations. The test sites were selected to represent different agro-climatic areas of Kentucky where corn is a major commodity. Please note that the Murray location was not included in the data analysis due to water damage and high variation in the testing environment. Cultural Practices Corn seed was planted no-till into soybean stubble at all locations. Fertilizer was applied as indicated by soil tests. All test areas were treated with herbicide(s) and insecticide(s) supplemented by post emergence herbicide when necessary. Force insecticide was applied in the row at planting to control corn rootworms. Specific cultural treatment for each location is included in that locations table, which includes notes about the growing season.

2 Experimental Design and Mean Comparisons Each hybrid was grown in three replications at each location to sample uncontrollable variability within the field. Annual mean yields presented in the tables are averages of three replications at the test site; 2-year and 3-year means are averages of six and nine replications, respectively. A randomized complete block design (RCBD) was used for each maturity group test at each location. These tests are designed to predict relative yield ability. In these tests, we are most interested in how Hybrid A yields relative to Hybrid B. Slight differences in yield ability can occur as a result of variability in the field. The least significant difference (LSD) is used to account for that variability and to help determine significant differences between hybrid performances. Consider the following example: Hybrid Yield (bu/acre) A 165 B 155 C 140 LSD (0.10) 12 The yield difference between Hybrid A and Hybrid B is 10 bu/ acre ( = 10). The difference is less than the LSD (12 bu/ acre). Based on the LSD, the yield difference between hybrids A and B is not significant, meaning that we would expect hybrids A and B to have the same yield capability the next season. Hybrids A and B have the same yield in this test. However the yield difference between hybrids A and C is 25 bu/acre ( = 25) which is greater than the LSD (12 bu/acre). The LSD indicates that we would expect hybrid A to have greater yield capability than hybrid C next year. The LSD occurs at the bottom of each table. Yields that are less than the LSD are not significantly different from each other. The notation N.S. in the tables indicates that no statistically significant differences were determined. An asterisk has been placed alongside yields that are not significantly different from the highest yield mean in that column. In addition, the tables are sorted from greatest yield to least yield. The coefficient of variation (CV) is a calculated value that helps indicate unexplained variation in these studies. A smaller CV indicates less unexplained variation and more precise results. Planting All plots were planted with a John Deere Maxi-Emerge vacuum, two-row, no-till planter modified for small plot work. Two-row plots are suitable for comparing performance of hybrids to one another. Each hybrid seed was planted into plots consisting of two rows 30 inches apart and 22 feet long. Hybrid seed was planted at 40 seeds/row for each plot. When seedlings were 12 to 18 inches tall, the stands were thinned to 36 plants/ row equaling 28,000 plants/acre. Harvesting All plots were harvested with a Massey Ferguson MF 8-XP two-row corn combine. Both rows of each two-row plot were harvested. The grain weight, moisture content, and test weight of corn from each plot was measured with an electronic scale and moisture meter mounted on the combine. Yields were calculated for grain at 56 pounds per bushel and adjusted to 15.5 percent moisture. The test weight reported in each annual table for any hybrid is not corrected for harvest moisture and is reported at the moisture content for that hybrid listed in that table. Dropped ears were not gleaned from the plots. The total number of lodged plants was recorded at harvest. Also at harvest, selected plots were observed to indicate apparent European corn borer damage by counting the number of broken tops per plot, according to a protocol by Dr. Rick Bessin, Department of Entomology, and University of Kentucky. Corn borer damage was minor at all locations. In general, hybrids with resistance to corn borer had less apparent corn borer damage than hybrids without corn borer resistance. Hybrid Comparisons The Kentucky Hybrid Corn Performance Test is divided into four tests: Early, Medium, Late maturities and White hybrids. These divisions provide evaluations of the hybrid groups without competition biases. The divisions do not allow for comparisons across groups. For example, a hybrid in the Early test cannot be compared to a hybrid in the Late. The Early, Medium, Late and White tests were grown at all six locations for a total of 18 tests. The Early maturity hybrid group in Table 4E, and all subsequent E tables, includes those hybrids rated by the parent seed company to mature in 112 days or earlier. The Medium maturity hybrid group in Table 4M and all subsequent M tables includes those hybrids rated by the parent seed company to mature in days. The Late maturity hybrid group in Table 4L and all subsequent L tables include those hybrids rated by the parent seed company to mature in 118 days or later. The White hybrid group in Table 4W and all subsequent W tables includes those hybrids with a white seed coat and rated by the parent seed company to mature in 112 to 118 days. Open-pedigree hybrids of known maturity were included in each Early, Medium, and Late test to provide an internal evaluation of hybrid maturity. The seed of these hybrids was obtained from Illinois Foundation Seeds, Inc., at Champaign, IL. Grain moisture of hybrids in the Early, Medium, and Late tests should be within the LSD of the check hybrid grain moisture for that test. Hybrids with grain moisture above the LSD of the check hybrid likely belong in a later-maturing test. Each hybrid is placed in the Early, Medium, and Late tests based on the hybrid maturity defined by the company. Notes about the 2011 growing season are next to each location data table. 2

3 Chemical Analysis of the Early, Medium, Late and White Tests Grain chemical composition was measured from one replication of each Early, Medium, Late and White maturity test at each location. These samples were analyzed by the Kentucky Grain Quality Laboratory at Lexington 1 using NIRS. The NIRS analysis provided evaluation of protein, starch, and oil and is presented in Tables 7E, 7M, 7L and 7W for grain at 0 percent moisture. Since grain used in feed rations contains moisture, the composition variables provided in Tables 7E, 7M, 7L and 7W should possibly be used at a moisture content that is different than 0%. Moisture that is acceptable in most feed rations is 15 percent. To covert to 15 percent moisture, multiply the values in Table 7 by For any other moisture content, multiply the values by (100 - % moisture)/100.
