Eastern Route - Day 2
Starts in Fishers, Indiana and ends in Bloomington, Illinois
Crop Conditions for McLean and Tazewell counties in central Illinois
- Some corn fields started showing severe drought stress starting at the end of June and conditions haven't improved since then.
- Corn fields that I've looked at will probably yield between 50-180 bu/A, with many averaging 100 bu/A.
- Corn crop that I've looked at is in the R5 stage, with some fields at least half way or further through the R5 stage. The crop isn't too far from being mature.
- In soybeans, the canopy remains in fantastic shape. Reasons why: beans were planted into excellent conditions and planted early, enabling soybeans to be pretty well rooted.
- Most soybean fields will likely yield between 35 to 70+ bu/A (in a few instances).

Western Route - Day 2
Starts in Grand Island, Nebraska and ends in Nebraska City, Nebraska
Nemaha & Otoe counties in southeast Nebraska
- Scouted an irrigated white corn field and ears are pretty well filled out and yield will be good.
- Dryland acres look very tough in southeast Nebraska and yield will be variable. Scouted one white corn field that will likely yield 50-60 bu/A. Another field with a different soil type, different planting date but same white corn hybrid will probably yield 120 bu/A.
- Disease pressure fairly light, seeing a little southern corn rust and gray leaf spot (later in the season). Goss's wilt is not spreading much this year. In dryland corn, ear molds are showing up, especially Aspergillus Ear Rot, which has the potential to develop aflatoxins.
- Insects: Heavy earworm pressure, especially in later-planted fields, virtually no European corn borer and isolated cases of corn rootworm in some areas.
- Scouted fields of mostly Late Group III varieties and these plants have good pod set. Very few pods on the bottom 1/3 of the plant but overall these plants have decent pod sets. What happens to the top 1/3 of the plant will make the yield difference but these soybeans need rain in the next 1-2 weeks.
- Insect pressure: bean leaf beetles are hit and miss, seeing a few stink bugs
- Diseases: Phytophthora & fusarium showed up after mid-June rains. Late-season phytophthora, fusarium and charcoal rot showing up. Some SDS showing up late.
Pioneer® brand Optimum® AQUAmax™ hybrids* shine in dryland
|Solid fertility program and good soils can prove beneficial even in a dry
year. White corn planted in dryland clay soils.
Late-season corn earworm feeding spotted in
Tough dry conditions in southeast Nebraska.
|Aspergillus Ear Rot is most common under
drought conditions, high temperatures
(80-100 F) and was spotted regularly in
southeast Nebraska leg of tour.
|Plenty of blooms still on plant...soybean yield
potential could increase by 5 bu. if southeast
Nebraska saw one more good rain.

Pro Farmer Crop Report
From my route through the Indian counties of Hamilton, Tipton, Clinton, Tippecanoe, Warren and Benton, we calculated a corn yield of 133.3 bu. per acre. We had a range of corn yield calcs from 80.3 bu. to 210 bu. per acre. While the corn was improved from what I had seen on Day 1, there were still only two fields that I felt represented "good" corn for the area we were in. The other seven samples showed the effects of stressful growing conditions. Of note, we saw a long stretch of hail damage in Tippecanoe Co., which further cut into yield potential.
For our Indiana soybean samples, we had an average pod count in a 3 foot by 3 foot square of 958.7, with a range from 583.9 to 1705.4. Many of the soybeans in the areas we were in had good topsoil moisture from recent rains. That will help to fill pods, but the beans we saw were done flowering.
The final numbers for Indiana showed a Tour-calculated corn yield of 113.25 bu., down 20.9% from year-ago. Soybeans in a 3x3 square came in at 1033.24, down 9.2%. Read the full report from Pro Farmer.

Day 2 of the Pro Farmer Midwest Crop Tour ended just like I hoped it would... all the scouts made it from Grand Island to Nebraska City safe and sound.
Unfortunately, we found exactly what we feared would. A poor corn and soybean crop in Nebraska.
We stopped and talked with Bob and Jeanie near St. Mary, NE, as they were harvesting their 2012 corn crop. It was dryland corn and the moisture level in a half-mile row ranged from 12.1% to nearly 18%. The yield monitor showed a yield that ranged from the low 30 bu. per acre to as much as 130 bu. per acre (again within the same half-mile row). That's an incredible example of how variable this year's crop is... if you can find 100 bu. yield difference within the same row, that should be all the evidence you need to understand how difficult it will be to estimate yields in the western Corn Belt this year. The final numbers for Indiana showed a Tour-calculated corn yield of 113.25 bu., down 20.9% from year-ago. Soybeans in a 3x3 square came in at 1033.24, down 9.2%. Read the full report from Pro Farmer.
