2021-2022 Small Grains Variety Performance Tests

Wheat Crop Overview

At the time of writing this report, 2022 Oklahoma wheat production is estimated to be approximately 65 million bushels, which is about 44% lower than 2021 production and 38% lower than 2020 production (Table 1). Approximately 4.4 million acres were planted for the 2022 crop year, similar to the 2021 crop but 14% lower than the previous 10-year average. Number of harvested acres is estimated at 2.4 million, which is 19% lower than in 2021 (Table 1). The statewide average yield is projected at 27 bu/ac. This is 12 bu/ac lower than the 2021 state average and 5 bu/ac lower than the previous 10-year average.

Dual-purpose wheat producers could not plant at the optimum time (mid-September) due to drought conditions in much of the state. Most of the wheat intended for dual purpose was “dusted in” and the emergence was delayed, but plants established well. Oklahoma received good rainfall in October, which helped the dual-purpose wheat to emerge and grow as well as enabled grain-only producers to plant under good soil moisture. Although dual-purpose wheat was planted later than desired, the October moisture enabled moderate fall forage production. By December 15, Oklahoma had not received 0.25” of rainfall for almost two months (since October) in some parts of the state and the wheat was showing signs of drought stress. Some fields were also showing symptoms of nitrogen (N) deficiency. There were multiple reports of fall armyworm infestations during the summer, but the later planting date of wheat limit the impact this pest had on the crop. 

 

December was warmer than usual with large fluctuations in temperature. By the end of year, the wheat crop was showing signs of drought stress and could benefit from additional moisture going into the winter. However, this moisture did not come until March.

 

Due to a lack of moisture late in the fall, wheat fields planted late, especially in southwest OK, did not emerge until February. This resulted in a lack of cold accumulation “vernalization requirement,” reduced growth, and tillering. The continual lack of rainfall during the winter made conditions unsuitable for wheat, and growers could not take the crop to yield. In other parts of the state where the crop was established in October and received some rainfall in March and April, yield potential was acceptable. However, with the exception of eastern OK, much of the wheat in the state was grown under drought stress. No diseases of any significance were observed in the fall.

 

Overall, average temperatures and low rainfall resulted in low to moderate fall forage production (for more information see CR 2141 - Fall Forage Production and First Hollow Stem Date for Small Grain Varieties during the 2020-2021 Crop Year). In the forage trials, the very early genotypes reached first hollow stem during the second week of February. By the end of March drought conditions became severe in many areas, and the crop was behind in growth in much of the state. Some parts of the state received decent rain on March 21, the most significant rain since planting. This rain saved many producers from not having a crop this year. However, some places, such as the panhandle and southwest regions, did not receive significant amount of rain. The lack of moisture during this critical plant developmental stage (from jointing to flag leaf stage) resulted in short wheat in many fields. Flag leaves turned blue and curled due to lack of moisture. The weather continued to be very hot and dry and prevented the emergence of many diseases. However, heavy infestations of brown wheat mites occurred throughout the state, except for the Panhandle and Eastern OK, and many producers decided to spray for it.

 

Wheat started to head by mid-April in southwest OK and late April in southcentral OK. Freeze occurred but the damage was minimal this year. Some fields showed heads with discoloration (i.e., bleached) or a dark chocolate color due to different types of stresses (e.g., freeze, drought and crown/root rots). By May, the crop looked good in some areas it needed rainfall to help with grain filling and test weight.

 

Viral diseases were the most common wheat diseases through April and May in Oklahoma. Wheat streak mosaic virus transmitted by wheat curl mite was widespread and severe in multiple fields. In previous years, wheat streak mosaic virus was reported mainly in northwestern OK; however, this season, it reached severe levels in several areas across the state. High plains, another viral disease, was reported at lower incidence in western and northwestern Oklahoma. Barley yellow dwarf occurred at moderate incidence and severity, with occasional fields showing high incidence. Barley yellow dwarf was reported in fields in Canadian, Payne, Grady, Cleveland and Garfield Counties.

 

Drought during this wheat growing season reduced the presence of many foliar fungal diseases. Low incidence of leaf rust was reported in Stillwater and east central Oklahoma in mid-May, whereas powdery mildew was relatively more prominent. Moderate incidence and severity of Septoria trites blotch were observed in some no-till fields in Kay and Okmulgee counties after the rain events mid-May. The moist conditions in Okmulgee County also favored bacterial streak, black chaff and Fusarium head blight diseases. Spot blotch was another fungal disease found at low to moderate incidence and severity in some fields in Payne, Garfield and Okmulgee Counties.

 

The lack of rain promoted Fusarium root, crown and foot rots across the state in moderate to high incidence and severity. Symptoms of these dryland diseases were noticeable during May. Common root rot, caused by Bipolaris sorokiniana and favored by drought, was found at lower incidence in fields in Alfalfa, Beaver, Blaine and Oklahoma Counties.

 

In summary, this year’s crop was thin and short, with a small head size and poor kernel set due to the severe drought it experienced throughout the season. Overall, the Oklahoma wheat crop was severely affected by lack of moisture and some fields were not harvested.

 

Most of the rain in the state came in the first two weeks of June. Consequently, harvest was delayed by a couple of weeks. According to the Oklahoma Wheat Commission report, grain yields of harvested wheat ranged from meager yields (10 bu/ac) in drought-stressed fields to higher yields (65 bu/ac) in intensively managed fields in northcentral Oklahoma. Test weight was good as harvest began, with values ranging from 58 to 61 lbs/bu. However, the continuing rainfall events during late June caused a slight decline in test weight and greater sprout damage in some areas. Sprout damage was rated 5-7%. Wheat protein varied from 10 to 16% across the state, with a state average of 12%. 

 

Testing Methods and Data Interpretation

 

Testing Methods

Seed was packaged and planted in the same condition as 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.

 

Plots were seven rows wide with 7.5-inch row spacing and were sown with a Great Plains no-till drill modified for conceded, small-plot research. . Except for 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. The experimental design for all sites was a randomized complete block with four replicates.  The intensive management trials at Apache, Morris, Chickasha and Lahoma received two fungicide applications, additional topdress nitrogen application and were planted on a seeds per acre basis. Fungicide was applied at Feekes 6 (jointing) and Feekes 9 (flag leaf completely emerged).Additional information on product name, rate and date of application is included in the tables for the respective sites.  

 

Plots received 5 gal/ac of 10-34-0 at planting. All variety trial locations were sown at 60 pounds per acre, except for the dual-purpose trials at El Reno and Walters, which were sown at 120 pounds per acre. The intensive wheat management trials at Apache, Chickasha, Lahoma and Morris were sown at 1.2 million seeds per acre. Grazing intensity, nitrogen fertilization, and insect and weed control decisions were made on location-by-location basis and reflect standard management practices for the area. In general, N rate was calculate for 70 bu/ac yield goal for the standard management trials and 100 bu/ac yield goal for the intensive management trials.  

 

Plots were harvested with a Winter stieger Delta small plot combine. Grain weight, test weight, protein concentration and moisture content were collected from each plot, and grain yields and protein concentration were corrected to 12% moisture content. Grain moisture at all sites was generally below 12%, and maximum and minimum grain moisture for all plots at a location typically ranged no more than 2%.  Similar to many wheat fields in the region, the Altus trial experienced severe drought stress throughout the growing season, with significant plant or tiller mortality and reduced kernel set, generating excessive variability across the field. This data would not be meaningful and misrepresent comparisons among varieties; thus, this site was not harvested in 2022.

 

Data Interpretation

Yield, test weight and protein 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, test weight and protein. In this report, one can be 95% confident that the difference between two varieties is real if the difference is greater than the LSD value.  Data that is not significantly different is indicated by “NS”. For example, if the LSD value is 4 bu/ac in a trial where Variety A yielded 30 bu/ac and Variety B yielded 25, then Variety A would be considered to have a statistically higher yield. However, if Variety C yielded 27 bu/ac, then Variety A and Variety C would be considered to have a similar yield. In that same example trial, there is a 5% chance that the 4 bu/ac difference between Variety A and Variety B does not truly exist, but random chance caused the 5 bushel difference. These chance factors may include differences in fertility, moisture availability, and diseases. To aid in visualizing the varieties with the highest yields, test weights and proteins, 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 performance of a variety

Note: Grain yield and protein concentration were adjusted to 12% moisture content. Shaded values are not statistically different from the highest value within a column. There was severe drought stress, and high pressure of brown wheat mites and fusarium root rots. We utilized a different statistical analysis for grain yield, test weight, and protein to reduce the impact of the spatial variability possibly caused by heavier fusarium root rots infestation on the north side of the experiment. Therefore, data from previous years will not be combined with the current year to provide long-term averages. The 2-year yield averages include the 2020 and 2021 harvest years.

The crop experienced drought stress during the season and received a few timely rains late winter and in the spring, which enhanced realized yield in this particular environment relative to the statewide yield average. The high rainfall events that occurred after maturity resulted in pre-harvest sprouting damage in some varieties. Sprouting damage was assessed by counting visibly sprouted kernels among 4000 kernels. There were no diseases observed in this trial. Lodging is reported on a 1 to 5 scale, with 1 indicating no lodging. In 2020, there were no harvest results from this location due to late-spring freeze damage. Thus, the 3-year average represent results from 2019, 2021, and 2022 harvest years. Double-dashes"--" = data not available.

Note: Grain yield and protein concentration were adjusted to 12% moisture content. Shaded values were not statistically different from the highest value within a column. The crop experienced drought stress during the season and received a few timely rains late winter and in the spring which enhanced realized yield in this particular environment relative to the statewide yield average. The high rainfall events that occurred after maturity resulted in pre-harvest sprouting damage in some varieties. Sprouting damage was assessed by counting visibly sprouted kernels among 4000 kernels. There were no diseases observed in this trial. Lodging is reported on a 1 to 5 scale, with 1 indicating no lodging. In 2020, there were no harvest results from this location due to late-spring freeze damage. Thus, the 3-year average represent results from 2019, 2021, and 2022 harvest years. IM= Intensive Management. Double-dashes"--" = data not available.

Note: Grain yield and protein concentration were adjusted to 12% moisture content. Shaded values were not statistically different from the highest value within a column. There was low to moderate presence of Barley yellow dwarf disease observed in this trial. Plots were grazed from 12/06/21 to 02/28/22 at an average stocking rate of 310 pounds of animal BW per acre. The crop experienced high rainfall conditions after maturity, which resulted in pre-harvest
sprouting damage in some varieties. Sprouting damage was assessed by counting visibly sprouted kernels among 4000 kernels The Falling number test was conducted to measure the alpha amylase activity, an enzyme that breaks down starch. The lower the falling number, the higher the enzyme activity, indicating poor grain quality A falling number above 300 seconds is most suitable for the bread-baking process.

Note: Grain yield and protein concentration were adjusted to 12% moisture content. Shaded values were not statistically different from the highest value within a column. The crop experienced drought stress during the season and received a few timely rains late winter and in the spring, which enhanced realized yield in this particular environment relative to the statewide yield average. There were no diseases observed in this trial. This was the first year to conduct an intensive management (IM) trial at Lahoma. Due to this addition and the use of a different experimental design, data from previous years were not be combined with the current year to provide long-term averages. Data from the trials conducted at Lahoma with and without fungicide in the 2020-2021 growing season are shown only for varieties planted in the 2021-2022 growing season. The 2-year yield averages include the 2020 and 2021 harvest years. Butler's Gold late-planted was planted on 12/3/2021 at 1.4 million seeds/acre. Double-dashes"--" = data not available.

Plots were grazed from 12/10/21 to 03/09/22 at a stocking rate of 160 lbs/ac. We utilized a different statistical analysis for grain yield, test weight, and protein to reduce the impact of the spatial variability possibly caused by greater moisture on the north side of the experiment. Therefore, data from previous years will not be combined with the current year to provide long-term averages. The 2-year yield averages include the 2020 and 2021 harvest years.

Note: The seeding rate column "Grain-only standard management" represents the number of seeds per acre for each variety when planted at 60 pounds per acre.  Thus, seeding rate was estimated by multiplying the amount of seeds per pound by 60 pounds per acre per variety. The reported seeds per pound reflect only the seed source used to plant the 2022 trials and may not approximate the long-term average for a given variety. All variety trial locations were sown at 60 pounds per acre, except for the dual-purpose trials at El Reno and Walters that were sown at 120 pounds per acre and the intensive wheat management trials at Apache, Chickasha,Lahoma, and Morris that were sown at 1.2 million seeds per acre.
