2018 Kentucky Hybrid Corn Performance Test

Transcription

1 PR-756 University of Kentucky College of Agriculture, Food and Environment Agricultural Experiment Station 2018 Kentucky Hybrid Corn Performance Test Richard C. Kenimer, Matthew W. Piersawl, and Dr. Chad Lee, Department of Plant and Soil Sciences The objective of the Kentucky Hybrid Corn Performance Test is to provide relative performance estimates of hybrid seed corn sold in Kentucky. The test attempts to treat every hybrid similarly in an unbiased manner. Agronomic practices that meet or exceed university guidelines are implemented at each location. Presentation of Data Complete 2018 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. If individual location data is used, it should be used in combination with a multiple location average. The multiple location tables present better estimates of hybrid yield ability than data gathered at a single 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, White, and Conventional 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 shaded gray. See Hybrid Comparisons and Experimental Design and Comparisons sections for more detail. Testing Procedure Selection of Hybrids The hybrids submitted for testing are those most likely to be available for sale in Representatives from seed companies select and nominate their own hybrids. They provide the seed listed in Table 1 and identify the maturity and/or seed coat color. Location of Tests The map on Page 2 shows the test locations (Figure 1). The test sites were selected to represent different agro-climatic areas of Kentucky where corn is a major commodity. There were six total tests from six locations across the state. Included in these six tests was one irrigated test in Daviess County. It was under center pivot irrigation. Seasonal Notes There were many challenges this year due to the weather. The main issue was too much rainfall in certain areas in the Spring. Carlisle County had to be excluded due to mechanical error across the entire test. Moreover, the Early, Medium, and Late tests were excluded in Caldwell County due to a very high CV. Disease Ratings Hybrids were evaluated at two locations Fayette County and Caldwell County. All ratings were made by Dr. Carl Bradley and Kelsey Mehl, UK Plant Pathologists in Princeton. Ratings were made during this middle of August. Princeton had low disease levels overall, so only Fayette County is reported. Special thanks to Dr. Bradley and Ms. Mehl for this work. Cultural Practices Corn seed was planted no-till into soybean stubble at four locations, corn stubble at one location, and into tilled fields at the other two. Fertilizer was applied in accordance with each individual farmer s practices. All test areas were treated with herbicides supplemented by post emergence herbicide when necessary. Experimental Design and Comparisons Each hybrid was grown in three replications at each location to sample uncontrollable variability within the field. Yields presented in the tables are averages of three replications at the test site; two-year and three-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 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. However the yield difference between hybrids A and C is 25 bu/acre ( = 25) which is greater than the LSD Agricultural Experiment Station Kentucky Tobacco Research and Development Center Veterinary Diagnostic Laboratory Division of Regulatory Services Research and Education Center Robinson Forest Robinson Center for Appalachian Resource Sustainability University of Kentucky Superfund Research Center Equine Programs

2 (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. Yield differences that are less than the LSD are not significantly different from each other. Tables are sorted from greatest to least yield. Cells that have been shaded gray are not significantly different from the highest yield mean in that column. The analysis indicates that all hybrids with yields shaded gray, would be expected to have similar yield potential next season. 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 Wintersteiger Dynamic Disk vacuum, four-row, no-till planter, which is specialized for small plot work. Each hybrid seed was planted into plots consisting of four rows 30 inches apart and 20 feet long. Hybrid seed was planted at a rate of 32,000 in the non-irrigated locations and at 36,000 at the irrigated locations. Harvesting All plots were harvested with a Haldrup C-85 two-row corn combine. The central two rows of each four-row plot were harvested. The grain weight, moisture content, and test weight of grain 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. The Kentucky Hybrid Corn Performance Test is divided into five tests: Early, Medium, Late maturities and White and Conventional (non-gmo) 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. All tests were grown at all six locations for a total of 30 tests. The Early maturity hybrid group in Table 2E and all subsequent E tables, includes those hybrids rated by the parent seed company to mature in 111 days or earlier. The Medium maturity hybrid group in Table 2M and all subsequent M tables includes those hybrids rated by the parent seed company to mature in days. Figure 1. Locations of the 2018 Kentucky hybrid corn performance tests. The Late maturity hybrid group in Table 2L and all subsequent L tables include those hybrids rated by the parent seed company to mature in 116 days or later. The White hybrid group in Table 2W and all subsequent W tables includes those hybrids with a white seed coat. The maturity for each hybrid is rated by the parent seed company. The Conventional hybrid group in Table 2C and all subsequent C tables includes those hybrids that are non-gmo hybrids. The maturity for each hybrid is rated by the parent seed company. Grain moisture of hybrids in the Early, Medium, and Late tests should be within the LSD for that test. Hybrids with grain moisture above the LSD 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. 2
