Southwest & Central Oklahoma
Wheat harvest continues to roll along in week 2. While great progress has been made in regions of Southwest, Oklahoma, some areas have had light rains over the weekend which has put harvest on hold. In the Altus region heavier rains were reported and will delay producers from getting back into the fields for the next couple days. Other parts of Southwest, Oklahoma have had light showers, while producers have not had to fight mud in most places, the light rains and high humidity levels have created delays with late starts on most days. In South Central Oklahoma, around Minco/Tuttle, and in North Central Oklahoma around Goltry producers over the weekend had light rains which have delayed harvest progress from really getting started in those regions. Overall crop quality continues to be favorable with test weight and yield reports. Statewide nothing has been reported below 60 lbs./bu. Yields in most all regions have been favorable ranging from the mid 30’s to mid 60’s depending on variety, location and management plans. A lot of yields across the state are reported in the low 40’s. We are seeing lower yields once you get west of Lone Wolf and Cordell, due to more intense drought situations that producers have been dealing with in that region all year. In the Southwest region proteins being reported are still in a favorable range of 11.5 percent. Harvest in many parts of this region are 50% to 60% completed, while in other parts some locations are reporting 20% to 30% completed.
The regions North of 412 Hwy from the Helena to Garber area, harvest is just getting started as several producers were able to start with test cutting over the weekend. Early indications from this region North in most places it is estimated that yields will be decent and mirror much of what we saw last year, with ranges from the mid 40’s to mid 60’s; although in some places lack of moisture during this spring seem to have impacted the crop especially around the Cherokee, Burlington and Alva regions. It is too early to report an accurate protein number on the crop that is being harvest in Central and Northern, Oklahoma, it looks like this also is going to mirror what we saw last year, with high pocket regions, and some areas that will be lower.
Below are regions where wheat has been taken in prior to Monday June 14, at 12:00 noon CST.
Southwest Oklahoma Locations Reporting
Duke- Harvest is progressing in this region. Yields have been ranging in the mid 30’s to mid 40’s. Test weights averaging 62 lbs./bu. to 63 lbs./bu. per bushel. Harvest in this region is 60% complete.
Altus- Harvest was successful in this region prior to heavy rains received over the weekend. This region received 1.4 to 1.9 inches of moisture over the weekend and harvest will be at a standstill most likely the next couple days. Test weights to this point ranging from 61 lbs./bu. to 63 lbs./bu. with yields being reported in the mid 30’s to mid 40’s for the most part. Harvest 50% to 60% complete.
Lone Wolf/Hobart- Wheat harvest continues in this region. Test weights averaging 61 lbs./bu. to 63 lbs./bu. Yields being reported from the mid 30’s to mid 50’s depending on location and management. Yields have been better around the Hobart area, due to more moisture received in this region throughout the growing season. Harvest in this region is 55% complete.
Roosevelt- Harvest in this region has been slower this year due to several untimely rains and high humidity days. Yields on the wheat in this region have been more favorable than other areas of Southwest, Oklahoma, due to more moisture throughout the growing season.

Sentinel/Rocky- Light rain showers and high humidity throughout the week have hindered harvest from getting into full swing. Custom cutters have been slower to arrive in the region due to harvest still going on in the Central/Northern Texas regions and other parts of Southwest, Oklahoma. Yields are being reported as favorable making in the upper 30’s to mid 40’s on early cuttings. Test weight on the wheat is ranging from 62lbs./bu. to 64 lbs./bu. Harvest in this region is 20% complete.
Central Oklahoma Locations Reporting
Reeding/Kingfisher/Omega- Yields in this region have been favorable up to this point in time. Harvest has been moving forward in this area for the past week, but it has been slower going with the scattered showers and high humidity. Yields for the most part are ranging from the mid to low 40’s. One yield was reported to make above 75 bushels per acre on a field with intensive management North of Kingfisher. Test weights have been ranging from 60 lbs./bu. to 64 lbs./bu. Harvest in this region will have a more accurate field count on Wednesday, but right now we are calling the area 35% to 40% harvested.
Northern Oklahoma Locations Reporting

The 2021 wheat harvest is on the move in most areas of Southwest, Oklahoma. Some places around the Frederick region have been slowed due to heavier rains, but producers are hopeful they will start getting back in fields later tonight or tomorrow. A large portion of Tillman County received ½ to 3 ½ inches of rain late Sunday evening and early Monday morning. In other parts of Comanche and Cotton counties where harvest has resumed, test weights have dropped slightly but are still favorable coming in at 60 lbs./bu. or higher. Other regions in Kiowa, Washita, and Caddo counties are also reporting extremely favorable test weights ranging from 62 to 63 lbs/bu. for the most part with a few being reported as high as 65.5 lbs./bu. Yields in most regions where harvest is being reported are coming in favorable across Southwest Oklahoma. They are ranging from the mid 30’s to the mid 60’s depending on climate, rainfall and management systems. We have had a report of one load of wheat being taken in at Clinton and harvest has also started with wheat being taken in at Sentinel, Rocky, Cordell and Apache. Producers have been test cutting East of Okarche and South of Kingfisher where harvest usually leap frogs over Grady and Canadian counties, but as of today, moisture ranges on test cuttings have been reported at 15.5% to 17.4% in the Kingfisher/Canadian county region. With the predicted forecast of warmer temperatures, producers are hoping they will get into the fields in this area late this afternoon. Proteins being reported in Southwest, Oklahoma are varying depending on locations, environment and producer management. Regional averages from Southern Oklahoma are currently holding steady at 11.3% to 11.6% based off early reports.
Below are regions where wheat has been taken in prior to Wednesday, June 9, at 12:00 noon CST.
Grandfield/Devol- Harvest was successful this past weekend and combines have started back up in these locations after the rains earlier in the week. Test weights have dropped from earlier reports last weekend but still are coming in at 60 to 61 lbs./bu. Yields being reported in the mid 30’s to the mid 50’s.
Frederick/Chattanooga- Harvest was successful this past weekend until heavy rains on Sunday and Monday morning took place. Producers are hopeful they will get back into the fields around Chattanooga later this afternoon. The Frederick region, is hopeful harvest will get moving at full speed tomorrow. Test weights in this region before the rains were being reported at 60 to 62 lbs./bu., with more data available on the next report. Yields were being reported as favorable in the mid 30’s to mid 40’s for the most part, with some higher yields in the mid 50’s noted.
Altus/Duke- Harvest was successful in this region over the weekend, while light moisture and humidity slowed harvest around Altus. Producers around Duke have been able to continue cutting and harvest in the Altus area now is moving full speed ahead. Test weights are coming in higher than some of the earlier harvested wheat, with reports now showing 62 to 64 lbs./bu. Yields being reported from high 30’s to mid 60’s depending on management systems.

During the last two days there have been a couple reports of dark wheat heads being observed in fields. This is a condition call sooty mold (aka black head mold) (Figure 1). These dark heads are the result of saprophytic (living of dead tissue) or weakly pathogenic fungi growing on the dead tissue in wheat heads. Reports of this have come from Greg Highfill (Alfalfa County Extension Educator in north central OK) and from Brad Secraw (Cleveland County Extension Educator in central OK). Additionally, I have observed severe sooty mold in some of the trials around Stillwater.
Sooty mold occurs when wheat has turned but cannot be harvested in a timely manner. Wet/humid conditions during a delayed harvest will then promote the fungal growth on wheat heads. Often wheat that has been subjected to a stress such as freeze, root rot, or drought shows a greater severity of sooty mold than if the wheat had been healthy and not stressed. This is the case in the top photo in Figure 1. The darker strips of wheat with sooty mold are the variety Pete, which was hit hard by the late freeze in April. The lighter, more golden colored heads with much less sooty mold are lines in one of Dr. Carver’s nurseries. These breeder lines were not nearly as affected by the freeze as was the Pete. Although grain yield from wheat with sooty mold often is reduced, the sooty mold itself is not the primary cause of that reduce yield. Rather, it was the stress such as a freeze or root rot that was the primary cause of the reduced yield.
One additional point to be made is that grain harvested from wheat with severe sooty mold may show a condition known as black point (Figure 2). Black point is a discoloration of the seed (typically the germ end of the seed) resulting either from infection by various fungi that typically are saprophytic but can occasionally parasitize living tissue, or from a combination of abiotic (environmental) conditions that promote the discoloration without the presence of an organism. Like sooty mold, black point often is observed when freeze damage has occurred or when harvest was delayed and dead tissue in the heads was heavily colonized by fungi that resulted in sooty mold. Black point in wheat grain can be a grading factor as the discoloration can result in black flecks in flour milled from such grain. Additionally, if used as seed wheat, kernels with black point can have reduce germination resulting in lower seedling emergence. Hence, if wheat showing black point is to be used as seed wheat, it is imperative to check the germination of that seed and to use a seed treatment that controls seed and seedling rots.
FINALLY – This likely will be my (Dr. Bob Hunger) last Wheat Disease update as my last day of work is July 9th. It has truly been a pleasure to send these updates!! I hope all of you have a great harvest this year and even better ones in the future!!!

The 2021 wheat harvest has begun with several locations in Southwest, Oklahoma, reporting a successful weekend for grain being received. The following counties that received grain in elevator locations were Harmon, Jackson, Tillman, Cotton, Comanche, Kiowa and Greer. A few reports of sample loads being accepted in Frederick on Saturday, May 29th. Rain showers across Southwestern, Oklahoma, over the Memorial Day weekend hindered producers from making any progress over this past week until Saturday, June 5th. During this period, cooler temperatures, cloud cover and high moisture levels on the grain have slowed progress on harvesting the crop. Traditionally combines are rolling in Southwest, Oklahoma Memorial Day weekend or before, but unseasonable cool temperatures and rain has delayed the crop maturing. High quality and favorable test weights have been noted so far. Rains across Southwest, Oklahoma, late last night and early this morning have put harvest on standstill again in several regions, while in other areas producers hope to get rolling again later this afternoon, west of Tillman and Kiowa counties. In a large area of Tillman county, producers are reporting 3 to 5 inch rains last night, which will delay harvest another 4 to 5 days. Regions of Cotton and Comanche county locations received 1/10th to 2.5 inches of moisture depending on location.
Overall early wheat that has been harvested in Southwest, Oklahoma, indicates strong quality and decent yields. Yields reported varied depending on locations and producer management. Test weights are averaging 60 lbs./bu. or higher. While it is premature to report on protein, early numbers are ranging between 11 and 12 percent.
Grandfield/Devol- Harvest started over the weekend, although moisture last night will make it a late start today. More moisture was reported around Grandfield with less rain in the Devol area where combines will likely start up again. Test weights for this region being reported at 60 +. Yields around Grandfield and Devol have been favorable ranging from 40 to 50 bushels per acre. One field has been reported at 70 bushels per acre.
Frederick/Chattanooga- The past two days have been successful for harvest in this region, but heavy rains last night across Tillman County is going to hinder harvest most likely another 4 to 5 days depending on the location. Three to five inch rains from elevator managers in this region being reported today. Areas of heavy rain did not report on Mesonet due to the nature of pop- up storms. Test weights ranging from 60 to 61 lbs./bu. Yields in this region not being reported as favorable as Comanche County but still ranging from the high 30’s on heavily grazed wheat to the mid 40’s on early cuttings.
Altus/Duke- Harvest was successful in this region over the weekend, while light moisture and humidity will most likely hinder harvest in Altus. Little rain was received out at Duke so producers are hopeful combines in this area as well as in Harmon and Greer Counties will move later today. Note: much of the wheat in Harmon and Greer counties was cut for hay due to the excessive ongoing drought in this region. Test weights in this area being reported at 61 to 62 lbs./bu. Yields being reported from high 30’s to mid 60’s on fields with extremely progressive management systems.
Lone Wolf/Hobart-Producers also had success with harvesting in this region over the past two days. Light rains and higher humidity will likely hinder an early start to harvest today in most places, certain regions may be delayed longer from getting into the fields in Kiowa county. Test weights in this region averaging 62.4 lbs./bu. Yields being reported from the mid 30’s to mid 50’s depending on location and management.
Sentinel/Rocky- While it was close to starting this weekend at these locations, light rains today will most likely hinder harvest another couple days in this area. No wheat was reported as taken in at these locations over the weekend.
Enclosed, see the 14-Day and 12-Hour rainfall accumulation maps with the 7-day weather forecast for Oklahoma.
The next harvest report by the Oklahoma Wheat Commission will be published Wednesday, June 9, 2021.
