What This Wheat Year Taught Farmers
A hard wheat year can still teach Oklahoma producers something useful about risk, timing, and variety decisions.
In this episode of the Red Dirt Agronomy Podcast, Dave Deken, Brian Arnall Ph.D., and Josh Lofton Ph.D. talk with Amanda Silva Ph.D., Oklahoma State University Extension small grains specialist, about the 2026 Oklahoma wheat crop. They discuss drought stress, scattered rainfall, early crop development, planting date decisions, test weight, wheat streak mosaic virus, and what variety trials can still tell farmers in a difficult year.
Key takeaways:
Detailed timestamped rundown
00:00–02:14 — Intro and setup
Dave opens Episode 514 by framing the conversation around the Oklahoma wheat crop and why a hard year can still shape decisions for future crops. He also promotes the Summer Crop Demo Day near Chickasha and introduces Brian Arnall Ph.D., Josh Lofton Ph.D., and guest Amanda Silva Ph.D.
02:17–06:19 — Field-tour context and statewide wheat observations
02:17–06:19 — Field-tour context and statewide wheat observations
The group talks about seeing wheat across Oklahoma through field tours, Oklahoma Wheat Commission work, and research stops from Apache and Greenfield to the Panhandle and northeast Oklahoma. Dave notes how seeing the crop in person gave a fuller picture than just looking at numbers.
06:27–09:10 — A hard, variable wheat season
06:27–09:10 — A hard, variable wheat season
Silva describes the season as one of the hardest since she started at OSU. She explains that southwest and western Oklahoma were especially rough, while some locations saw enough rain to produce pockets of better wheat. Rainfall patterns created major differences, even between fields in the same county.
09:11–12:02 — Stand establishment, planting timing, and grain fill
09:11–12:02 — Stand establishment, planting timing, and grain fill
Josh compares the wheat variability to what he saw in canola. Silva and Arnall discuss how some locations benefited from earlier establishment, while others struggled with stands and canopy closure. Cooler weather during grain fill likely helped preserve some grain quality and test weight.
12:04–15:17 — Why wheat matured early
12:04–15:17 — Why wheat matured early
Arnall asks why wheat was running ahead of schedule across a broad region. Silva points to warm late-winter and early-spring temperatures that moved the crop through growth stages quickly. The group also compares how those conditions affected canola and freeze risk.
15:17–17:40 — The critical period for yield
15:17–17:40 — The critical period for yield
Silva explains that the jointing-to-flowering period is especially important because key yield components are being set. Moisture or stress during that window can strongly shape final yield.
17:45–20:35 — Diversifying planting dates
17:45–20:35 — Diversifying planting dates
Arnall raises the idea of spreading planting dates as another form of risk management. Silva agrees that stacking planting dates could help, especially when combined with different variety maturities. She clarifies that “early” for grain-only wheat may still mean mid-October, not September.
20:36–23:53 — Dusting in wheat and chasing moisture
20:36–23:53 — Dusting in wheat and chasing moisture
Dave asks when dusting in becomes worth the risk. Silva explains that farmers and researchers both have acreage and time constraints, and sometimes planting dry is a practical choice. The group also discusses deeper planting, coleoptile length, and whether Oklahoma could learn from dryland systems in the Pacific Northwest and Australia.
23:54–28:13 — How much water does wheat really need?
23:54–28:13 — How much water does wheat really need?
Dave asks whether researchers can determine a minimum moisture requirement for wheat in a controlled setting. Arnall and Lofton explain why lab or pot-study answers do not always translate well to field decisions because soil, temperature, humidity, wind, rooting environment, and other factors change the outcome.
29:09–32:19 — Silva’s research program
29:09–32:19 — Silva’s research program
Silva outlines current OSU wheat work, including planting date, variety maturity, nitrogen management in late-planted wheat, seeding rates, forage response, grazing recovery, nitrogen uptake, protein, and nitrogen-use efficiency. She notes new forage-focused seeding-rate work at El Reno and possibly Chickasha.
32:20–36:47 — Variety trials and disease pressure
32:20–36:47 — Variety trials and disease pressure
The group discusses OSU’s wheat variety trial network, the number of varieties being evaluated, and the inclusion of irrigated wheat work in the Panhandle. Silva notes wheat streak mosaic virus pressure in irrigated plots and explains that water alone does not remove the impact of disease.
36:48–45:45 — How researchers judge trial data
36:48–45:45 — How researchers judge trial data
Arnall asks Silva and Lofton to explain how they decide whether trial data is trustworthy. They discuss CV, blocks, reps, averages, plot-by-plot review, field notes, drone imagery, canopy gaps, and the challenge of publishing fair comparisons when field variability is high.
45:46–49:10 — Lessons from a stressful wheat year
45:46–49:10 — Lessons from a stressful wheat year
Silva’s big takeaway is the resilience of wheat and Oklahoma producers. The group points out that hard “scientist years” can reveal useful information about stress tolerance, variety response, and management, even when they are not the years producers hope for.
