Oklahoma summer crops may look smaller than usual, but that does not automatically mean yield potential is gone. Dave Deken talks with Brian Arnall Ph.D. and Josh Lofton Ph.D. about how timely June rains, cooler temperatures, and still-uncertain July weather are shaping corn, soybeans, grain sorghum, hay, and double crop decisions across the Southern Plains. The conversation covers why smaller soybeans can sometimes offer better yield stability in dryland Oklahoma, what corn needs during pollination, how growers are thinking about double crop acres after an early wheat harvest, and where fertilizer dollars may be best spent with current nitrogen, phosphorus, potassium, and lime prices. Brian also shares lessons from Brazilian row crop systems, and the team previews a hands-on OSU Extension summer crop field day in Chickasha. Key takeaways June rain changed the summer crop outlook. After a dry start, many Oklahoma fields caught enough rain to germinate and carry crops forward.Smaller crops are not automatically bad. In dryland Oklahoma, shorter soybeans and sorghum may use less water and hold up better if July turns hot and dry.Corn is in a critical window. Cooler temperatures in the 70s and 80s could help early planted corn during pollination.Soybeans are already moving. Some April-planted soybeans are flowering, but wide-row fields that have not canopied may face more weed pressure.Double crop decisions remain complicated. Moisture is favorable in places, but prices, risk, and plans for next wheat crop are slowing some decisions.Some growers may invest in existing acres first. Instead of adding more double crop acres, producers may spend fertility dollars on full-season corn, sorghum, or soybeans.Hay and forage acres may increase. Hay grazer could see more interest as producers rebuild hay supplies for winter.Potassium and lime may deserve attention. Brian points to K and lime as places to invest where soil tests show a need, while staying cautious on expensive N and P.Fertilizer markets are global. Nitrogen, phosphorus, and potash prices are being shaped by international demand, freight, geopolitics, and timing.Brazil offers useful contrasts. Brian’s trip highlighted major differences in soils, rainfall, row crop systems, planter setup, fertility, and crop disease pressure. Detailed timestamped rundown 00:00–01:43 — Episode setup and introductions Dave introduces episode 513 and frames the discussion around moisture, cooler weather, wheat harvest, summer planting, and what has changed across the Southern Great Plains.01:48–04:55 — Weather whiplash and wet wheat harvest areas The group jokes about June feeling like winter and discusses wet conditions in northeastern Oklahoma, including areas where wheat harvest had been delayed by repeated rainfall.04:55–07:18 — “Weird things called rain” Josh explains that after a very dry early spring, rain finally arrived. Instead of one big soaking event in many areas, crops benefited from more spread-out rainfall.07:18–09:37 — Double crop decisions and crop progress The group discusses wheat coming off, double crop choices, cooler temperatures, corn approaching pollination, and early planted soybeans beginning to flower.09:37–13:10 — Josh’s research projects Josh outlines current work, including crabgrass and small grain rotations, nitrogen management, forage production, soybean and sorghum herbicide work, and pigweed control research.13:10–14:16 — How research programs evolve Brian and Josh talk about how Extension research shifts through phases based on grower needs, student interests, funding, and emerging problems.14:16–17:02 — Summer crop acreage trends Josh says corn interest increased after strong performance last year, soybeans remained steadier than expected, and marketing conditions have made decisions feel like choosing the least bad option.17:02–18:40 — Early wheat harvest and double crop caution Brian notes how early wheat harvest was in some areas. Josh says some growers are considering whether to double crop or prepare ground for wheat again.18:40–19:44 — Fertility and hay grazer decisions Josh says some growers may spend money on full-season acres instead of double crop acres, while also considering lime, phosphorus, potassium, and hay grazer needs.19:45–20:55 — Bermuda grass and hay outlook Brian notes Bermuda grass started slowly because of the dry, cool start, but second cuttings may look stronger. Josh adds that eastern Oklahoma avoided some flooding problems seen in previous years.21:08–22:23 — Dry planting, then June moisture The group compares expectations at planting with current field conditions and notes that Oklahoma growers would rather have moisture in June than early growth with no rain later.22:23–24:02 — Why small crops may be okay Josh introduces the idea that smaller soybean and sorghum plants may offer yield stability in Oklahoma by lowering water demand.24:02–26:21 — ...
