Still Time For Soybean Yields?
Less than one-third of the soybeans were planted leading into the delay, but there’s still time in the optimum planting window.
“It’s really not late at all as far as soybean planting is concerned,” said Lance Tarochione, DeKalb and Asgrow territory agronomist.
“We have talked a lot in recent years about some of the research that shows that early planting of soybeans does tend to increase your yield potential. I’m a believer in that, but for many, many years, the target planting window for soybeans was basically the month of May and we really didn’t think we started losing yield potential until June 10.”
He added more recent research indicates the soybeans’ yield potential is reduced more rapidly when planted later, “but you can still raise very, very good beans in Illinois planted in May.” “I’m not terribly concerned about the fact that there are a lot of soybeans to be planted,” Tarochione said.
It’s also much too early to consider increasing planting population as the calendar gets nearer to double-crop timing.
“I don’t really worry about that until I get into the second half of June. I’m still recommending standard seeding rate,” Tarochione said.
I've seen Keith Schlapkohl break 100 bushels per acre planted June 19. I would be lucky to break 60 and more like 50 bushels. I would rather plant beans in April and have them out of the ground in May. We are seeing bean leaf beetle on the early plantings as they have nothing else preferable to eat.
The old Ohio State Agronomy Guide says those beans should be in the second trifoliate by now. The earliest fields are.
I hope the guy isn't selling soybean seed because I think too many are going to be planted this year due to price and weather. Planting delays lowers yield expectation but I agree good yields can still be obtained.
