Nebraska Corn Falls Short While Soybeans Stay Steady

August 23, 2016 08:27 PM

After two days in the fields, scouts on the Pro Farmer Midwest Crop Tour have their doubts about the prospect of achieving the record 187 bpa corn yield projected by USDA in August.

“I’ve been a little disappointed by the ear counts,” said Luke Lauritsen, who farms in Arlington, Nebraska. “They’ve been a little light.”

On Tuesday, for example, he scouted 13 cornfields in districts 8 and 9, which cover counties like Thayer, Pawnee, Nuckolls and Adams. His route’s average ear count: 75.15, which proved to be below the state average of 87.65, according to Pro Farmer data.

Even irrigated corn fields appeared to be running below expectations. Lauritsen’s group took samples from three irrigated fields that produced an average rough yield of 184.33.

Scouts’ suspicions were confirmed Tuesday night, when Pro Farmer crop tour data showed a rough yield of 158.6 for Nebraska, a drop of more than 6.5 bushels per acre from 2015.

Dry conditions certainly could be taking a toll on Nebraska corn. “Last year, you couldn’t tell the difference between dryland and irrigated corn in this part of the world,” said Jarod Creed, director of customer risk management for Gavilon.

Green snap has also been a problem in the state. In Nemaha County, scouts found a field with 30% green snap. “Every third stalk was green snap,” said Lauritsen. The rough yield? A painful 80 bushels per acre.

Cornfields in Burt, Dodge and other surrounding areas also revealed green snap from a late June storm that brought damagingly high winds. “It was Tuesday, June 28,” recalled master crop tour scout Tim Gregerson, who farms in Herman, Neb. “We had 70 mile an hour winds.” The severe weather lasted for three days, damaging cornfields that had been replanted that spring and were at the pre-tassel stage.  “It affected a strip about five to 15 miles wide, from Columbus to Omaha,” Gregersen added.

The storm certainly wreaked havoc on farmers’ fields, leaving corn stalks twisted and snapped. In Burt County, for example, scouts found one of those fields, which had a rough yield of 163 bushels per acre, according to Pro Farmer calculations. Others saw far worse, such as a Clay County field shown in the scout video below.

Year over year, though, ear counts were up slightly in Nebraska with an average of 87.65, as were kernel rows, with a statewide average of 16.26. But grain length dropped by 5% to 6.80 inches.

The situation was different for soybeans. “I thought the beans were impressive, with a lot of good pod counts,” said Lauritsen.

According to Pro Farmer data, Nebraska soybeans held steady in 2016, with an average of 1,223.07 pods in a 3 x 3 square. That’s essentially the same as last year, when scouts found an average of 1,220.02 pods per 3 x 3 square. (Unlike corn, the Pro Farmer Midwest Crop Tour does not estimate yield for soybeans, just potential for yield.)

Those numbers could go higher if the weather cooperates. In contrast to the wet and muddy fields experienced by last year’s Western leg scouts, the soil this year has been dry and cracked. In 2015, Pro Farmer scouts reported an average moisture level of 4.89 in Nebraska’s soybean fields, with a “5” indicating recent rains. This year, that fell more than a full point to 3.73.

Another big difference from last year: weed pressure. While scouts found many clean soybean fields, they also found fields choked with waterhemp plants between four and five feet tall.

What happened? Farmers might have missed the date for pre-emergence weed treatment or chosen not to apply one, due to cost concerns.  They might have planted corn the year before and not realized just how bad their waterhemp problem had become, hidden behind the corn plants.

Whatever the reason, though, “It’s now a real mess,” said scout Lawrence Landsteiner, who farms in Minnesota. A typical waterhemp plant can produce 250,000 seeds, which can then survive in the soil for as long as four years, according to the University of Missouri Extension.

It’s also a yield robber, with the power to reduce corn and soybean yields by 15 to 44%, according to North Dakota State University.  With one particularly bad waterhemp-infested field in Webster County still posting a potential of 1,3194.94 pods, it left scouts wondering what sort of yield that farmer might have seen with better weed control.

  I find this very interesting. I realize that all the data has yet to be collected and analyzed, but it appears that the actual crop tour is showing that USDA may have "over shot" the target.........And yet the corn market keeps slipping and sliding.......?? I guess real data means little to the traders??

  The last few years the higher yielding Nebraska irrigated corn farmers have applied fungicide at V5-7 and again at brown silk. Myself included. This year with cash corn in the low $3 area, I chose to apply none. I believe there was a lot of farmers chose not to invest in fungicide this year. This fact is not going to show up until the corn is in the bin as that is when the10 to 20 BPA test weight gain shows up(56, 57, 58 lb. test weight instead of 60,61 ,62.5 lb. test weight we have had using fungicide). It will obviously not be there this year since very little was applied this year. On a side note, I applied fungicide to every acre I had of those $10.00+ per bushel soybean acres! Both Irrigated and non irrigated. The potential yield increase with that price made it pencil out ok. Thank you, Alan Hoehne , Stanton county Nebraska
