Farmers look at early corn and soybean yields as harvest kicks off


“It saved my bean crop,” he recalls. “My soybeans were going to be the size of BB (balls). The plants were done, they didn’t put any more pods, but it filled what was there.

Before the rains, Svaty suspected his beans would drop to 10 bpa; now he hopes some will reach 20 bpa. The experience amazed him at the improved soy genetics that made the humble legume an increasingly attractive option for the semi-arid plains of Kansas.

“Here is a plant that does not require a lot of inputs, and although it is a bet in a hot and dry environment, it is a safer bet than it has been in the past”, a- he declared.

For the first time in many years, Kyle Samp believes he’s reaping a truly average crop where he grows near Moberly, Missouri. “I think our corn yields won’t be too far off our APH (actual production history),” he concluded. “Usually we’re way above or below – it’s pretty rare to have a crop that’s really just average.”

It didn’t start like that. In early August, when Samp roamed his fields with DTN’s Digital Yield Tour, his corn looked poised to be a solid crop that would reach a farm-wide average of 175 bpy, far from its record high. 2014 at 214 bpa, but impressive considering the turbulent weather his region experienced in early summer.

But now, as the combine scours these fields, it finds out the true cost of those heavy June rains and the loss of nitrogen that followed.

“We had two different weeks that month where we had over 10 inches of rain,” Samp said. “It was right after we got undressed, and I think in the end we ended up running out of nitrogen.” Test weights are stagnant between 53 and 54 pounds, and Samp suspects his farm-wide average will slide closer to 150 bpa.

“If you look at the weather for Missouri – from Kansas City to the northeastern corner of the state, where most of the state’s corn production is located – I think what we see will be enough. current, ”he added.

As for soybeans, a rain in mid-August saved them from a disaster, and a month ago Samp was optimistic they could give in in the mid-1950s if the weather continued to cooperate.

But the region’s turn to hot and dry in late August and early September also put them down to average, Samp said. “I think the soybeans will be small,” he said. “I don’t think we can even do an average of 50 bpa.”

A hot, dry mid-August and a severe windstorm dashed hopes of an explosive harvest for Lindsay Greiner of Keota, Iowa.

During yield checks in early August for the DTN Digital Yield Tour, Greiner believed corn would on average be well over 200 bpa, maybe 240 bpa on acres of corn after soybeans. Average soybean yields above 60 bpy could not be ruled out either. Timely rains and overall good weather up to this point have given farmers in southeast Iowa optimism for a bountiful end to the growing season.

But the weather was not good for Greiner after the crop assessment of the yield tour. A period of about three weeks without rain and too much heat likely reduced corn yields by 20 to 30 bpa and a few bushels for soybeans, Greiner said. And yields will likely be cut in half on 200 acres of corn lying mostly flat on land he cultivates near Sigourney, Iowa, he continued.

“The harvest isn’t done until it’s in the bin,” said Greiner. “We will definitely be collecting insurance (on wind damaged corn).”

On September 15, Greiner combined 15 acres of corn continuously. It averaged 22% humidity and 200 bpa. “The (undamaged) corn will still be good enough but will not reach the numbers we were hoping for in early August.”

Greiner said he plans to start seriously combining corn next week and soybeans in 10 days (September 25). “I hope soybeans will average 60 (bpy).”

The grain and livestock producer noted that some rains in late August had helped crops, likely enough to halt a further decline in yields.

As of September 14, Gro Intelligence predicts average Iowa corn and soybean yields at 199.4 and 58.7 bpy, respectively. Both are just slightly better than the company’s early August estimate.

The USDA September average corn yield estimate for Iowa is 198 bpa, up 5 bpa from August. The agency increased the state’s average soybean yield projection in September to 59 bps, up 1 bp from August.

Scott Wallis’ corn crop is about 30% complete, and these fields are on average 19 bpf above their respective records. Many of those field-level records were set in 2017 and 2020, two of his best years for corn yields. But some of the best fields he’s harvested so far – like the two DTNs he visited with him in late July – were planted with soybeans in those years, which he says gives that average a boost.

When DTN visited Wallis, a simple yield formula estimated these two fields at 236 and 208 bpa, but the combine counted them at 289 bpa and 255 bpa, respectively. This is more in line with what Wallis expected after this year’s superb growing conditions and his senior management agronomic approach.

“Our ears are no bigger than anyone else’s, but each nucleus contains a lot more,” he said, adding that a formula that does not take into account the weight of the nucleus, like that used in the Digital Yield Tour, is missing an important part of the equation. (You can find an in-depth discussion of yield formulas here:….)

Some of the hybrids he plants have really grown in girth in the last two to four weeks before the black coat, and a leading agronomist at Beck’s Hybrids has told him that every 2/10 of an inch in girth adds about 20 bpa. Each additional 1/8 inch core depth adds an additional 20 bpa.

“The weight is just hard to quantify in July,” he said. “The USDA that doesn’t do anything on the ground until September is probably smarter than I thought.”

Gro Intelligence predicts corn yields in Gibson County, where Wallis operates, at 195 bpa, but Wallis believes the county average will be closer to 200 bpa. While there is a lot of varying terrain – river bottom, clay hills, white soil, and black soil – they all have a good season. Gro puts the county average at 58 bpa, which Wallis says must include double crop soybeans. Most high-season beans seem to give much better yields.

He’s just starting to grow soybeans, but he cut 150 acres that DTN visited in July, which averaged 95 bushels per acre. One of those four fields has hit 99 bpy before, and although Wallis said he was a little disappointed that the average didn’t hit the century, it still seems like the best harvest he’s ever had. .

“It’s tough when your backyard looks really, really good or really, really bad to think about the whole country,” he said, but he thinks the USDA will likely end up with an estimate. corn production of 15 billion bushels. “Within 50 miles of here, it doesn’t matter if you are senior, middle, or agronomically weak, you have the best crops you’ve ever had. It’s just a different number.

Matt Bennett says the yields on his farm near Winsor, Ill. Are satisfactory, especially with current prices. He cut about 250 acres of corn with yields in the range of 240-270 bpa. He cut only one field of soybeans, but his average was 80 bpa.

“It’s just hard enough to get worked up about these returns,” he said. “But in all fairness, I was hoping we might have 100 bushel beans. I think it could still be. It’s possible. Of course you want to ring that 300 bushel corn bell,” and yes, some guys are talking about it. “

He says there have been spots in areas that have reached this mark, but no area has yet reached that average. The weather in his area has been near ideal, with constant rainfall and high temperatures. There was a 4 inch rain last spring followed by cold weather which encouraged replanting.

“To get that 300 bushel corn, you have to have a lot of rain. And when you have a lot of rain, there are spots in the field, even though you have field tiles, which are a little wetter.” From the cab of the combine, it is clear that these wetlands have run out of nitrogen. But, overall, he says he’s lucky. Farmers in other parts of the state, particularly western Illinois, face many diseases and late-season illnesses due to the humidity that has hit yields hard. This year, spraying the crops twice seemed to make a big difference in yield.

When DTN visited Bennett for the Digital Yield Tour, he gave Illinois a 50-50 chance to break the state record. The USDA still considers this to be the case, maintaining its forecast for a statewide corn yield of 214 bpa in its September report, but Bennett isn’t so sure. He thinks Gro’s forecast for Illinois at 205 bpa is more likely.

“I don’t think the USDA will cut something like that in October, but I can see them saying Illinois is only 209 or 210. I can see them pushing Iowa up a bushel or two. I think the national yield will have to go down a bit, maybe a bushel. “
