Wheat Tech Agronomy Wheat Variety Performance Test Results

1 Wheat Tech Agronomy Wheat Variety Performance Test Results General Information: The wheat variety performance tests were conducted at three different sites: Adairville, Kentucky; Humboldt, Tennessee; and Bertrand, Missouri. The KY location contained 63, the TN location contained 54, and the MO location contained 55 different varieties. Varieties were tested in conventional till (MO), minimum till (TN), and no-till (KY) practices. The preceding crop for all locations was corn. Seeding rates used for the conventionally and minimum tilled sites were 325 s/yd 2, while no-tilled rates were 375 s/yd 2. Trials were planted using a Hege Drill with a row spacing of 7.5 inches, and were harvested with a Kincaid 8-XP research combine. Plot dimensions used were 5 feet wide by 20 feet long. All sites contained four replications, and the experimental design used was randomized complete block. All locations were managed intensively with split applications of nitrogen, insecticides, herbicide sprays in the fall and spring, and a spring foliar fungicide for head blight control. Nitrogen applied to the KY and TN locations was a January/March split application where the rate at KY was 45/85 pounds per acre, and the rate at TN was 55/67 pounds per acre. Nitrogen at MO was applied in a three pass application program during the months of January, March, and April at a rate of 37/37/80 pounds per acre. At the Kentucky no-till site, there were four replications treated with a foliar fungicide and four without. The objective for having four untreated replications is to see how each variety responds to the given level of head blight and create a yield fungicide response column. At the Tennessee and Missouri sites all replications were sprayed with a foliar fungicide. Growing Season: Throughout the month of October, planting went well at all locations. KY was planted October 12, MO planted October 14, and due to some rain events which delayed planting, TN was planted on October 26. Cold temperatures from November through March prohibited early season growth and tiller development on many acres of late planted wheat in all regions. As recorded from our on-site weather station, the average temperature for the month of November was 44 degrees Fahrenheit, and the average for December was 39 degrees Fahrenheit. The KY statewide average temperature for March based on the Kentucky Mesonet was 39.8 degrees while the statewide average temperature for March 2012 was 57.9 degrees, according to Dr. Stuart Foster, state climatologist and director of the Kentucky Mesonet. The poor fall growing conditions combined with excessive nutrient uptake from the high yielding corn crop called for increased levels of nitrogen to be applied. Applications were delayed this year as much as two weeks at some locations. Small to moderate amounts of Fusarium Head Blight were detected across all locations, however; reports of higher than normal DON levels in the Missouri bootheel region created concern for many growers. This delayed growth development lead to wheat harvest also being postponed more than in recent years. Data Interpretation: Maturity groups are separated out into the following classifications: E = Early M = Medium L = Late ME = Medium/Early ML = Medium/Late The tables on the following pages have been prepared with the entries listed in order of performance, the highest-yielding entry being listed first. All yields presented have been adjusted to 13.5% moisture. At the bottom of the tables are there are three different values: LSD (Least Significant Difference), CV (Coefficient of Variation), and Grand Mean. The mean yields of any two varieties being compared must differ by at least the LSD amount shown to be considered different in yielding ability at the 5% level of probability of significance. CV is a measure of the error variability found within each experiment. It is the percentage that the square root of error mean square is of the overall test mean yield at that location. Grand Mean is the mean of all values in the group.
