2018-2019 Small Grains Variety Performance Tests

September 2019


Wheat Crop Overview
According to the August 2019 USDA crop report, Oklahoma wheat production is estimated to be approximately 110 million bushels, which is about 57 percent greater than 2018 production (Table 1) and 12 percent greater than 2017 production. The increase in total grain production is the result of 250,000 more harvested acres than 2018 and much greater yield per acre. The 4.3 million acres planted in the 2019 crop year was a 2 percent decrease compared to the previous year, and was 16 percent lower than the previous 10-year average. The number of harvested acres is estimated at 2.75 million, which is 10 percent greater than in 2018 (Table 1). The statewide average yield is projected at 40 bushels per acre, which would be a new record. This is 12 bushels per acre (43 percent) greater than the 2018 state average and 11.5 bushels per acre (40 percent) greater than the previous ten-year average.

The 2018-2019 wheat growing season was challenging from establishment through grain-fill, but the end result was a harvest that exceeded expectations for most producers. Dual purpose wheat producers in most areas of the state benefitted from a full profile of moisture in early September and favorable conditions for wheat growth. Wheat forage production was well above average, with some varieties producing more than
2 tons of forage per acre by mid-December (see CR 2141 Fall forage production and first hollow stem date for small grain varieties during the 2018-2019 crop year for more information).
The same rains that fueled fall forage growth kept many grain-only producers from planting in a timely fashion. Sowing wheat in late October through the end of November was the norm, and many wheat fields entered the winter months still trying to emerge or with only one or two leaves. Cool conditions further delayed development and occurrence of first hollow stem was approximately one week later than the long-term average. Fortunately, moderate temperatures and ample moisture allowed a late-emerging and under-developed wheat crop to add tillers and develop a plant canopy.
Conditions for wheat development and grain fill remained mostly favorable until excessive rainfall events in May had many producers again questioning whether or not a wheat crop would be harvested in 2019. The October 1, 2018 – July 22, 2019 time frame was the fourth wettest on record for Oklahoma, and May stood out as an extreme month in an already wet production year. The Oklahoma Mesonet station at Lahoma, for example, recorded 12.7 inches of rainfall in May 2019, which is approximately 8 inches more than normal. The Kingfisher station reported 15.9 inches of May rainfall, which is more than 10 inches above normal. Several fields were complete losses due to flooding, and several additional fields were severely lodged from waterlogged soil conditions. There was concern that waterlogged soil conditions would adversely affect seed development and seed fill, resulting in poor yields or low test weights.
These wet and cool conditions also paved the way for severe disease incidence and severity in the 2019 Oklahoma wheat crop, especially in north-central Oklahoma. Few diseases were observed during the fall of 2018, with leaf rust at a low incidence being the primary disease reported. Lack of disease in the fall was probably the result of a significantly later planting date across much of the state as discussed above. Foliar disease also was slow to start in the spring, but with the cool and moist weather extending into the late spring, both rusts (leaf and stripe) and the leaf spot diseases (Septoria, Stagonospora and tan spot) were much more widespread and severe across Oklahoma in 2019. Often, Septoria and Stagonospora were found on the upper wheat leaves and flag leaf, which is atypical in Oklahoma. At many locations, foliar diseases were not observed until well into May, and a few locations (e.g. northwestern Oklahoma and the Panhandle) had lighter foliar disease pressure than the rest of Oklahoma. Most locations in north-central and central Oklahoma had at least one foliar disease of moderate to high severity with a few locations having a high severity of several diseases. Septoria and leaf rust remained the most prominent diseases across the state. Physiological leaf spot was detectable on some cultivars when symptoms of Septoria or leaf rust were delayed or suppressed by a fungicide treatment.
Root rots (primarily dryland root rot caused by the fungus Fusarium) and black chaff (caused by the bacterium Xanthomonas) were more prevalent than typical for Oklahoma. Fusarium head blight (scab) also occurred primarily in northeastern Oklahoma, but fortunately did not occur at a high incidence over the main wheat area of Oklahoma. Barley yellow dwarf was sporadic and was observed at only a few locations. The wheat curl mite-transmitted virus diseases (wheat streak mosaic, Triticum mosaic and high plains disease) were found but not nearly to the level as found in the past couple of years. Delayed planting is a recommended management strategy for these insect-vectored diseases, and the delayed planting associated with the wet fall probably helped reduce the incidence of barley yellow dwarf and the mite-transmitted virus diseases. Powdery mildew was observed at a lower incidence and severity than in most years. In summary, it was a very active year for diseases in Oklahoma with the mild and wet weather facilitating many diseases. The mild and wet weather also improved yield prospects by the time producers were making decisions regarding application of foliar fungicides, and many producers chose to protect yield potential with foliar fungicides. Data from fungicide treated and nontreated variety trial comparisons at Lahoma, Apache and Chickasha provide indication of the impact of foliar disease on grain yield and suggest that applying a foliar fungicide was a profitable decision for many Oklahoma wheat farmers in 2019.
Harvest started approximately one week later than normal, with no reports of wheat harvested prior to Memorial Day in 2019. Rainfall resulted in a very slow and intermittent start to harvest and waterlogged soil conditions presented challenges. Weather and soil conditions improved by mid-June, and harvest continued at a steady pace until conclusion in the latter half of July in the Oklahoma Panhandle. Grain yields exceeded expectations with some of the best yields coming from Harper County west through the Panhandle. The delayed harvest and waterlogged soil conditions did result in some low test weights, but the extent of the damage varied by geography and variety.

Testing Methods
Seed was packaged and planted in the same condition as it was delivered from the respective seed companies. Most seed was treated with an insecticide plus a fungicide, but the formulation and rate of seed treatment used was not confirmed or reported in this document.
Conventional-till plots were eight rows wide with 6-inch row spacing and were sown with a Hege small-plot cone seeder. No-till plots were seven rows wide with 7.5-inch row spacing and were sown with a Great Plains no-till drill modified for cone-seeded, small-plot research. With the exception of dryland locations in the Panhandle, plots were planted 25 feet long and trimmed to 19 feet at harvest with the plot combine. Panhandle dryland locations were 35 feet long at planting and trimmed to 29 feet at harvest. Wheel tracks were included in the plot area for yield calculation, for a total plot width of 60 inches. Experimental design for all sites other than Apache and Lahoma was a randomized complete block with four replications. Apache and Lahoma were a split-plot arrangement of a randomized complete block with four replications where whole plots were fungicide treated or non-treated, and sub-plots were wheat variety.
Conventional-till plots received 50 pounds per acre of 18-46-0 in-furrow at planting. No-till plots received 5 gallons per acre of 10-34-0 at planting. The Marshall dual-purpose (DP) trial, Union City, Walters and forage trials were sown at 120 pounds per acre. The Panhandle irrigated and dryland locations were sown at 90 and 45 pounds per acre, respectively. All other locations were sown at 60 pounds per acre. Grazing intensity, nitrogen fertilization and insect and weed control decisions were made on a location-by-location basis and reflect standard management practices for the area.
Plots were harvested with a Hege or Wintersteiger Delta small plot combine. Grain weight, test weight and moisture content were collected from each plot, and grain yields were corrected to 12 percent moisture content. Grain moisture at all sites was generally below 12 percent, and maximum and minimum grain moisture for all plots at a location typically ranged no more than 2 percent. The Afton plots were harvested, but data are not reported as the trial coefficient of variation (c.v.) exceeded 25. The Marshall plots were not harvested due to severe weed pressure.

Data Interpretation
Yield and test weight data for each location and regional summary were analyzed using the appropriate statistical methods. At the bottom of each table, the mean and least significant difference (LSD) values are reported. The LSD is a test statistic that aids in determining whether there is a true difference in yield or test weight. In this report, one can be 95 percent confident that the difference between two varieties is real if the difference is equal to or greater than the LSD value. Data that is not significant is indicated by “NS.” For example, if the LSD value is 4 bushels per acre in a trial which Variety A yielded 30 bushels per acre and Variety B yielded 26, then Variety A would be considered to have a statistically greater yield. However, if Variety C yielded 27 bushels per acre, then Variety A and Variety C would be considered to have a similar yield. In that same example trial, there is a 5 percent chance that the 4-bushels-per-acre difference between Variety A and Variety B does not truly exist, but random chance caused the five-bushel difference. These chance factors may include differences in fertility, moisture availability and diseases, for example. To aid in determining the varieties with the highest yields and test weights, values highlighted in gray do not differ statistically from the highest value within a column. The performance of a variety may vary from year to year, even at the same location. Tests over two or more years and over multiple locations more accurately predict the variety performance.
