CORN GRAIN HYBRID TESTS IN TENNESSEE

2020 Experimental Procedures: AgResearch and Education Center Tests: All corn hybrid trials were conducted in each of the physiographic regions of the state. Tests were conducted at the Highland Rim (Springfield), East Tennessee (Knoxville), Milan (Milan) and West Tennessee (Jackson) AgResearch and Education Centers. The early and medium-season tests were also planted at the Agricenter International Research Center (Memphis). Duplicate plantings of the early-, medium- and full-season tests were made at the Milan and Highland Rim AgResearch and Education Center for performance testing with and without irrigation.

The corn hybrids were placed in either the early-, medium-, or full-season tests based on the maturity as reported by the company providing the hybrid. The early season test contained hybrids that had maturity 116 DAP. All corn hybrid trials were planted to uniform populations per acre at each location using a precision seeding planter. Trials were planted with a goal of 36,000 plants per acre for irrigated plots and 34,000 plants per acre for non-irrigated plots, although final populations varied by location (Table 1). Tests were conducted using 30-inch row spacing. The tests were fertilized with approximately 230 lbs N/a. A portion of the nitrogen was applied prior to planting (e.g., 80 lbs/a) and the remainder was applied as a side-dress (e.g., 150 lbs/a). The plot size was two, 30-ft. rows. Plots were replicated three times at each location. An incomplete block design was used at each location in order to reduce the within replication variation.

County Standard Tests: The County Standard Corn Tests were conducted in 21 counties in Tennessee. The number of counties depended on the test. The County Standard Tests were divided into early-, medium-, and full-season glyphosate resistant and Bt stacked trait tests (same DAP criteria as listed above). Each hybrid was evaluated in a large strip-plot at each location, thus each county test was considered as one replication of the test in calculating the overall average yield and in conducting the statistical analysis to determine significant differences. At each location, plots were planted, sprayed, fertilized, and harvested with the equipment used in the cooperating producer’s farming operation. The width and length of strip-plots were different in each county; however, within a location in a county, the strips were trimmed on the ends so that the lengths were the same for each variety, or if the lengths were different then the harvested length was measured for each variety and appropriate harvested area adjustments were made to determine the yield per acre.

Growing Season: Corn grain official variety trials were planted between early April and early May at the University of Tennessee AgResearch and Education Center locations. Early season rainfall delayed corn planting throughout most of the state, with heavy rainfall and late frost affecting corn planted in early April. Statewide corn planting remained 2% to 9% behind the five-year average through the end of May. By May 24, 86% of corn had been planted, compared to the five-year average of 95%. Once planted, warm weather and adequate rainfall resulted in good growth. By mid-August, 74% of the crop rated good to excellent, which is lower than the previous year by 14 percent. Tropical storms which occurred at the end of September and early October brought a fair amount of rain and delayed corn harvest across the state ,which put corn harvest 20% behind the five-year average, with only 60% of corn grain harvested by the beginning of October. According to the National Agricultural Statistics Service, Tennessee producers planted 950,000 acres this year, a decrease of 20,000 acres from 2019. Acreage harvested for grain is projected to be 900,000 acres with a total production of 156 million bushels. This is a decrease of 5 million bushels compared to 2019. Average yield for Tennessee in 2020 is projected to be 174 bu/a which is 4 bu/a greater than national average in 2020 and on par with the state average in 2019.

Interpretation of Data: The tables on the following pages have been prepared with the entries listed in order of yield performance, the highest-yielding entry being listed first. Mean separation was performed using the Fisher’s Protected LSD (Least Significant Difference) test. The mean trait value of any two entries being compared must differ by at least the LSD amount shown to be considered significantly different at the 5% level of probability. Tests with an LSD value of N.S. indicate there were no significant differences in entry performance within that test. To simplify interpretation, Mean Separation Letters have been listed next to traits evaluated across locations. Hybrids that have any letter in common are not significantly different at the 5% level of probability based on the LSD test. Hybrids with performance statistically equivalent to the top performing hybrid will have an “A” included in the list of mean separation letters next to that entry.

The coefficient of variation (C.V.) values are also shown at the bottom of each table. This value is a measure of the error variability found within each experiment. It is calculated as the ratio of the square root of error variance to the mean yield. For example, a C.V. of 10% indicates that the size of the error variation is about 10% of the size of the test mean. Similarly, a C.V. of 30% indicates that the size of the error variation is nearly

4

one-third as large as the test mean. A goal in conducting each yield test is to keep the C.V. as low as possible, preferably below 20 percent.

Results Yield and Agronomic Traits. Eighty-seven corn hybrids were evaluated in the 2020 AgResearch and Education Center tests in Tennessee. There were 28 hybrids in the early- (Tables 3-6), 39 hybrids in the medium- (Tables 7-10), and 20 hybrids in the full-season (Tables 11-14) tests. These hybrids represent 15 different brands (Table 16). The County Standard Tests consisted of an early-season glyphosate resistant and Bt stacked trait test (18 hybrids at 7 locations, Table 5), a medium-season glyphosate resistant and Bt stacked trait test (23 hybrids at 14 locations, Table 9), and a full-season glyphosate resistant and Bt stacked trait test (10 hybrids at 8 locations, Table 13) for a total of 51 hybrids. Common to both the AgResearch Center and County Standard tests were 13 early-season, 14 medium-season, and 7 full-season hybrids (Tables 6, 10, 14). Similar to the Center tests, all hybrids in the County tests were placed in the maturity test for which they fit, regardless of other traits associated with each entry.

Eighty-two of the hybrids evaluated were transgenic, while five hybrids were conventional. All of the transgenic hybrids contained genetic modification for a combination of herbicide tolerance (RR, RR2, LL) and insect tolerance (A4, CB, HX1, Q, SS, TRE, VIP 3330, VR, VT2P, VZ, YGCB) (see table 17 for full descriptions of abbreviated traits). The majority of entries had glyphosate herbicide tolerance and VT2P insect tolerance. The breakdown of traits by entry are listed below:

Irrigated vs. Non-irrigated Yields. Duplicate tests were conducted with and without irrigation at Milan and Springfield. At the Springfield location, irrigated tests far out-yielded non-irrigated tests. Irrigated yields exceeded non-irrigated yields by 56, 67 and 95 bu/ac in the Early, Medium and Full test, respectively. At Milan, yields were more similar between the irrigated and non-irrigated tests with higher yields in the non-irrigated test. Non-irrigated tests out-yielded irrigated tests by 14, 8 and 14 bu/ac in the Early, Medium, and Full test, respectively.

† Hybrids that have any MS letter in common are not significantly different at the 5% level of probability.* Hybrids marked with an asterisk were in the top performing "A" group across locations for two (**) or three (***) years within the previous three year evaluation period.‡ For a full description of abbreviated biotech traits, see table 18.§ All yields are adjusted to 15.5% moisture.¶ Lodging values do not typically follow a normal distribution, therefore statistical tests to compute LSD were not performed and only mean values are reported. Values highlighted in light orange are above average for a given trait, MS letters highlighted in dark orange are in the "A group", indicating no statistical difference from the top-performing variety, for a given trait.
