At the time of writing this report, 2018 Oklahoma wheat production is estimated to be 52.0 million bushels, which is 47% less than the 2017 production (Table 1) and 62% less than the 2016 production. The lower total grain production is the result of less wheat acres harvested across the state, primarily from abandonment due to drought or baled for hay, and the below-average yield. The 4.3 million planted acres was only down 4% compared to the previous year, but that was still 18% lower than the previous ten-year average. Number of harvested acres is estimated at 2.0 million, which is 31% less than in 2017 (Table 1), and the lowest number in the state since 1913. The statewide average yield is projected at 26 bu/ac. This is 8 bu/ac (24%) less than the 2017 state average and 3.6 bu/ac (12%) less than the previous ten-year average.

The 2017-2018 wheat growing season was a fight from start to finish for many producers across the state. The growing season got an early start due to an unusual August for Oklahoma. Temperatures were below normal, and rainfall totals were above normal for the month. This prompted producers interested in targeting fall forage to begin planting at the end of August. Planting continued to move rapidly through the Labor Day weekend, and most of the wheat during this time was sown into adequate soil moisture and emerged rapidly. Those producers who waited until after Labor Day to plant saw more unfavorable conditions as temperatures rose, and available soil moisture quickly dried up. Wheat planted during this time was “dusted-in” and finally received precipitation toward the end of the month into the beginning of October to get the seed to germinate. Wheat planting intended for grain-only was stalled during the average timeframe of early to mid-October due to these precipitation events. Once the ground dried enough, most producers were able to quickly make up time and get the crop planted, but some needed until November to finish.

After mid-October, the rain quit falling for the remainder of the calendar year. Crop conditions during the early part of the season were average but quickly deteriorated as the season progressed. This also led to a disappointing fall forage production and grazing season for most producers. Those who planted during late August to early September and were able to protect the crop from fall armyworm achieved good stands and had some available pasture later in the fall. However, those who waited until after Labor Day or later to plant were not as fortunate. The later planting and lack of precipitation resulted in low total fall forage production or no available pasture at all.

Drought conditions and average to below average temperatures persisted throughout January into February. Even for the producers who had available fall pasture, the drought conditions limited the overall number of days of grazing.

Some precipitation finally fell in parts of the state during late February into early March. For many fields, this was the first precipitation received since planting. Below average temperatures were observed coming out of winter, and plants broke winter dormancy later than normal. Below average temperatures persisted, resulting in slow overall growth and development during this time. The first hollow stem growth stage was reached for many varieties during the second to third week of March, which was 7 to 10 days later than normal. Unfortunately, the rain received during late February to early March was not quite enough to give any grazed wheat the boost it needed to recover well.

Overall growth and development continued at a slower than normal pace due to the second coldest April on record. Three separate and widespread freeze events also occurred during the first week of April, resulting in significant injury in some areas. Most wheat headed during mid- to late April because of the cooler temperatures, with this being 7 to 14 days behind normal. The prevailing thought was that this would translate into a later than normal harvest. However, the cold temperatures in April were followed by the warmest May on record. The warm temperatures and lack of rainfall advanced the crop quickly at this point, resulting in suboptimal conditions for the grain-fill period.

Most wheat was mature in southwestern Oklahoma by the end of May and by the beginning of June in the central to northern parts of the state. Producers for the most part were not delayed by rainfall events, and with the dry weather during June, much of the wheat was harvested timely and quickly. Overall, harvest was almost complete in the state by late June.

Yields throughout Oklahoma were variable depending on location but were below average overall. Part of this variability was due to overgrazing and whether an area caught or missed a rainfall event during early spring. Field averages of 15 to 30 bu/ac were the norm across much of the state, but higher averages, even into the 50 to 60 bu/ac range, were not uncommon in some areas that received timely rainfall. Test weights throughout harvest remained at or above 60 lb/bu for early-harvested fields and did not drop much below the upper 50’s towards the end of harvest. Protein content also remained at or above acceptable levels.

Different insects were a concern at times during the growing season, but few were widespread or season-long outside of the fall armyworm. Unless treated, the fall armyworm devastated those producers who planted in late August into early September. Many fields had to be replanted, and some producers commented that this was the worst that they had ever observed. Unfortunately, some reports indicated the fall armyworm was still causing damage into early November. The dry weather experienced across the state through the winter provided ideal conditions for winter grain mite and brown wheat mite to thrive on wheat plants coming out of winter dormancy, and there were some reports of fields warranting control. Aphids were not really on the radar screen of most producers until mid-March, but this pest was still not the limiting factor as observed in other years. Despite the low aphid numbers, Barley Yellow Dwarf (BYD) was evident in some fields as flag leaves and heads started to emerge. While there was quite a bit of leaf purpling and yellowing associated with BYD, there was not much stunting observed, with stunting resulting from “hot spots” of aphid pressure with early-season transmission of the virus. Wheat Streak Mosaic (WSM), transmitted by the wheat curl mite, was an issue again for producers in southwestern Oklahoma,

but the overall impact of WSM was not as much as the 2016-2017 crop season. Reasons for this were related to later planting and emergence of some wheat; additionally, fields which may have had WSM were abandoned due to the drought or cut and baled for hay before symptoms could be observed.

Diseases were at low levels overall during the season, primarily due to the drought conditions. Parts of central to southcentral Oklahoma did experience low levels of powdery mildew, leaf rust, and stripe rust. In some cases, powdery mildew could be observed high in the canopy. For the remainder of the state, it was difficult to find foliar diseases, especially during stem elongation into the grain-fill period. One disease more prominent than in years past was Fusarium foot dry (dryland root rot). Signs and symptoms of this disease appeared suddenly during early May as hot temperatures returned and as the crop progressed through grain-fill. However, symptoms of this disease can appear similar to symptoms of premature death caused by freeze, drought, and other conditions. In parts of the northwest and panhandle regions, symptoms of dryland root rot may have been confused with symptoms caused by the drought and/or freeze, whereas in others (such as the wheat variety trial at Lahoma), damage caused by the April freeze events was expressed distinctly earlier. Because of the impact that leaf rust and stripe rust have had over the past several years, producers were ready to apply a foliar fungicide to susceptible varieties, but unfavorable conditions for disease development did not warrant an application in most cases. Variety trial results from Apache and Lahoma indicated that producers in these areas were justified in not spraying, as no evidence of a positive response to a fungicide application was found. However at Chickasha where low to medium levels of leaf and stripe rust and medium to high levels of powdery mildew were present, the two fungicide applications implemented at this location contributed to protecting the yield potential for a number of varieties compared to the non-treated plots of those same varieties.

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 six-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 lb/ac of 18-46-0 in-furrow at planting. No-till plots received 5 gal/ac of 10-34-0 at planting. The Marshall dual-purpose (DP) trial, Union City, Walters, and forage trials were sown at 120 lb/ac. The Panhandle irrigated and dryland locations were sown at 90 and 45 lb/ac, respectively. All other locationswere sown at 60 lb/ac. 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 Winterstieger Delta small plot combine. Grain weight, test weight, and moisture content were collected from each plot, and grain yields 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%.

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% 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 indicted by “NS.” For example, if the LSD value is 4 bu/ac in a trial which Variety A yielded 30 bu/ac and Variety B yielded 26, 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 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.

Kingfisher Wheat Variety Trial

Cooperator: Tary Helt Extension Educator: Zack Meyer

Notes: Grain yields adjusted to 12% moisture content. Shaded values are not statistically different from

the highest value within a column. Drought conditions persisted throughout much of the growing season.

This, coupled with freeze injury sustained during early April, resulted in sloughed tillers. Low foliar

disease pressure was observed during grain-fill, but Fusarium foot rot was present throughout the trial during the latter part of grain-fill.

Notes: Grain yields adjusted to 12% moisture. Shaded values are not statistically different from the highest value within a column. NS = not significant. Negative

yield and test weight responses to the fungicide application are statistically non-significant and should be regarded as no response. Freeze injury occurred during

Notes: Grain yields adjusted to 12% moisture content. Shaded values are not statistically different from the highest value within a column. Boldfaced values in the "Diff." column represent

a statistical difference between the dual-purpose vs. grain-only averages for that variety. Plots were grazed from 12/8/17 through 3/8/18 at a stocking rate of 1.12 ac/hd. Cattle were

removed when Duster reached first hollow stem (3/8/18). Some freeze injury occurred during early April. Low foliar disease pressure observed during grain-fill.

Experimentals

Notes: Grain yields adjusted to 12% moisture content. Shaded values are not statistically different from the highest

value within a column. Severe drought conditions persisted throughout much of the growing season, and some freeze

injury occurred during early April. There was low foliar disease pressure throughout grain-fill, but Fusarium foot rot

(dryland root rot) symptoms appeared during May and remained throughout grain-fill. Rainfall during mid-June prevented

a timely harvest. As a result, all varieties began to shatter before beging harvested. Shattering was rated for each plot

using a 0 - 10 scale with 0 representing no shattering and 10 representing complete shatter loss.

† Three-year results are the average of 2018, 2017, and 2015. Data was not collected in 2016 due to severe hail

damage in early May.

IntroductionFall forage production potential is one of the major con-

siderations in deciding which variety to plant. Dual-purpose wheat producers may find varietal characteristics, such as grain yield after grazing and disease resistance to be more important selection criteria than an advantage in early forage production potential. Forage-only producers might place more importance on planting an awnless wheat variety or one that germinates readily in hot soil conditions. Ultimately though, fall forage production is a selection criterion that should be considered.

Fall forage production potential is determined by genetics, management and environmental factors. The purpose of this publication is to quantify some of the genetic differences in for-age production potential and grazing duration among the most popular small grain varieties grown in Oklahoma. Management factors such as planting date, seeding rate and soil fertility are very influential and frequently more important than variety in determining forage production. Environmental factors, such as rainfall amount and distribution and temperature also play a heavy role in dictating how much fall forage is produced. All of these factors, along with yield potential after grazing and the individual producer’s preferences, will determine which variety is best suited for a particular field.

Site descriptions and methodsThe objective of the fall forage variety trials is to give

producers an indication of the fall forage production ability of small grain varieties commonly grown throughout Oklahoma. The forage trials were conducted under the umbrella of the Oklahoma State University Small Grains Variety Performance Tests. During the 2017-2018 crop year, the forage trial was conducted at Chickasha, Haskell and Stillwater test sites. Additionally, first hollow stem measurements were collected at Chickasha and Stillwater. Weather data for those locations are provided in Figures 1 through 3.

A randomized complete block design with four replications was used at each site. Plots at each location were established in a conventionally tilled seedbed and received 50 pounds per

acre of 18-46-0 in furrow at planting. The seeding rate for each small grain at all three locations was 120 pounds per acre for wheat, triticale and rye; 96 pounds per acre for barley; and 65 pounds per acre for oat. Forage was measured by hand clipping two, 1-meter by 1-row samples approximately ½ inch above the soil surface from the interior rows within each plot. Two separate forage clippings were collected at each loca-tion. After the first clipping at Chickasha and Stillwater, plots were mowed to 2.5 inches to simulate grazing. For these two locations, the results for each clipping is presented, and the combined total of the two clippings represents the fall forage yield potential. At the Haskell location, plots were not mowed after the first clipping. For this location, the results for each clipping are presented and represent a forage stockpiling scenario. All samples were placed in a forced-air dryer for approximately seven days and weighed. Fertility, planting date and clipping date information is provided in Table 1.

First hollow stem sampling began at the end of Febru-ary at the Stillwater and Chickasha locations and continued every three to four days on a by-variety basis until varieties reached first hollow stem. Plant samples were collected for each variety by digging an approximately 8-inch section of row and selecting 10 plants randomly from this sample. The largest tiller on each plant was split longitudinally, and the hollow stem below the developing grain head was measured. Varieties were considered at first hollow stem when the aver-age of the 10 plant samples was 1.5 cm or greater.

ResultsThe 2017-2018 wheat fall forage production season can-

not be described other than disappointing for most produc-ers. Adequate soil moisture was present at the end of August through the first few days of September. Those who planted during this window and were able to protect the crop from fall armyworm achieved good stands and had some available pasture later in the fall. However, for those who waited until mid-September or later to plant, the soil moisture quickly dried up and most wheat was sown into dry conditions. Some pro-ducers did receive precipitation in late-September, but other

than that, the rain did not return for the rest of the fall. The result was a limited number of days of grazing or no avail-able pasture at all. Dry conditions also remained throughout December, January and into February. A widespread rainfall event finally occurred in late February. Temperatures toward the end of winter remained cool, and the wheat broke winter dormancy almost two weeks later than normal. Although the cooler temperatures persisted throughout the time for cattle removal, the dry conditions did not provide a good opportunity for grazed wheat to recover. The forage trial at Stillwater was ‘dusted-in’ on Sept. 15. The trial received 3.5 inches of rain from Sept. 25 to Sept. 27 and another 3.5 inches of rain on Oct. 4. Unfortunately, the portion of the field where the triticale, barley, rye and oat plots were located had significant ponding issues, and that portion of the trial had to be abandoned. Fortunately, the winter wheat varieties were at least spared from this issue. Limited growth occurred during the fall and little forage accumulated after the simulated grazing in November. Average total winter wheat fall forage production at Stillwater was 1,480 pounds per acre (Table 2), which was 1,310 pounds per acre less than the 2016 average and 1,200 pounds per acre below the 10-year

average at this location. The range in forage production was 1,840 to 1,080 pounds per acre. The forage trial at Chickasha was sown into moist soil, and good stands were established. However, overall growth was less throughout the fall and, similar to Stillwater, limited regrowth occurred after the simulated grazing in November. The average total fall forage production at Chickasha was slightly better than Stillwater at 2,060 pounds per acre (Table 3), which was 1,860 pounds per acre below 2016 and 720 pounds per acre below the four-year average at this location. The range in total forage yield was 2,560 to 1,490 pounds per acre. Average total fall forage production for the triticale, rye, barley and oat varietes was 1,940; 2,180; 1,950; and 1,020 pounds per acre, respectively (Table 4). The Haskell location also received limited rain in the fall. The rains were timely, however, and the forage production was much greater. Average winter wheat forage collected in December was 4,190 pounds per acre (Table 5). The average forage production for the triticale, rye, barley and oat varieties was 3,770; 3,960; 4,110; and 4,900 pounds per acre, respec-tively (Table 5).

First hollow stem data are reported in ‘day of year’ (day) format for the winter wheat varieties in Table 6 and the triticale, rye, barley and oat varieties in Table 7. To provide reference, keep in mind that March 1 is day 60. The begin-ning of 2018 was the opposite of that experienced in 2017. Cooler-than-normal temperatures resulted in a much later break from winter dormancy, and overall crop development was slow during this time. The average winter wheat first hollow stem date at Stillwater was day 70 (March 10). This was 19 days later than in 2017 and 10 days later than the 20-year average at this location. At Stillwater, there was a 20-day difference between the earliest and lastest varieties, compared to only a nine-day difference in 2017 and a 15-day difference in 2016. The average winter wheat first hollow stem date for the Chickasha location was 64 (March 4). There was a 25-day difference between the earliest and latest varieties, compared to a 12-day difference at this location last year.
