Japanese beetles could take a hit from the cold weather.

I-75 Crop Tour presented by Agro-Culture Liquid Fertilizers – Day 2


Presented by: Agro-Culture Liquid Fertilizers

Mercer County

 Corn Summary: No-till continuous corn in R3 to R4 growth stage. We did notice some wind lodging and leave tearing. A little N firing on lower leaves. There was some NLCB and GLS about as heavy as we have seen, but still not yield limiting. There could be stalk quality issues that result. We saw some grasshoppers in the field. Good ear fill. Yield estimate 177 bushels. 

Soybean Summary: In 15-inch rows after wheat with a vertical tillage pass. Canopy height was 44 inches and the first node was at 9 inches, but 3 inches between higher nodes. Low disease pressure with some downey mildew. Some Japanese beetle feeding. Plants at R3 or early R4. This may be nicest bean field of the I-75 tour so far. Excellent yield potential.




Darke County 

Corn Summary: We did see some green snap and root lodging, but neither showed up in population count — maybe less than 5%. Population around 26,500 in this corn after corn conventional till field. Disease was minimal and similar to what we have been seeing. There were signs of N deficiency and varying ear height. Corn was at dough stage. Yield estimate 191.5 bushels.

Soybean Summary: Drilled, no-till 7.5-inch beans that look like they were planted after a cover crop. Canopy height 34 inches. First node height 4-5 inches and disease pressure was low with some brown spot. There were moderate to high populations of soybean aphids and other feeding as well. They are at R4 pod stage with population around 180,000. Overall fair to good yield potential. 





Shelby County

Corn Summary: Conventional tilled corn after soybeans with considerable root lodging and green snap. There was some N firing in lower leaves at early R4 stage. Some GLS evident even at ear leaf. The ears were well filled and nice but the populations were reduced down to the 20,000 to 28,000 range, which really hurt yields. Field was fair with estimated yield at 160 bushels.

Soybean Summary: Drilled 7.5 inches with conventional tillage in beans after beans. There was quite a bit of morning glory weed pressure that will likely affect harvest. Canopy height at 36 inches and the first node was at four inches and four inches on up between nodes. A few grasshoppers present and no disease pressure to speak of. Growth stage early R3 with population of 190,000 to 200,000 with fair yield potential.  




Miami County

Corn Summary: No-till corn after beans with very spotty stand with population range of 21,000 to 29,000. There may have been some planter challenges here which hurt yields. Crop in the dough stage with no real disease or insect pressure. Yield range very wide with average yield estimate of 182 bushels.

Soybean Summary: This was 15-inch row spacing conventionally tilled after corn. The canopy was 36 inches with 7inch first node height. There was some brown spot present in lower leaves. There was moderate Japanese beetle feeding. We also found what we initially thought to be a brown marmorated stink bug, but instead appears to be a spined soldier stink bug which is actually a predator of other insects. It was in the R4 stage with 171,000 plants per acre. The yield potential was a good to excellent. 





Champaign County

Corn Summary: Conventionally tilled corn after soybeans in some very good soils. There was some firing on the lower leaves with some pockets of green snap and root lodging. GLS and Northern Corn Leaf Spot along with some insect and bird feeding on exposed ear tips. There were a significant number of exposed tips with up to 2 inches in tip die back. Good field at the R5 stage with 181-bushel yield estimate.

Soybean Summary: Vertical tillage with 15-inch rows and a 40-inch canopy height. Brown spot, frogeye and downey mildew all present. The frogeye was moderate to severe and the heaviest we have seen. There were fresh sprayer tracks in field. Medium leaf feeding from Japanese beetles approaching threshold. It was a variable rate planted field with 130,000 population in low ground. There were signs of stress on hills with populations of 170,000 to 180,000. The overall potential is good to excellent.

Clark County

Corn Summary: Excellent field with no disease pressure or insect pressure in field with corn/soy rotation. Had hog manure injected prior to planting. Liquid fertilizer applied for three seasons with a 28,000 to 29,000 population. Yield estimate 190  bushels.

Soybean Summary: Beans planted 15-inch with conservation tillage after corn. Canopy height was 39 inches and 3 to 4 inches to first node. Minimal disease with some brown spot and some Japanese beetle feeding. The population averaged 138,000 in this field with good to excellent yield potential.

Montgomery County

Corn Summary: Conventional tillage after soybeans with some root lodging and a little green snap. There was a little N firing on the lowest leaves. There was some GLS and Northern Corn Leaf Spot, but very minimal. No insect pressure. It was at early R3, which is a little behind what we have seen. There was some spotty pollination, but we did find an ear with 22 around. The estimated yield is 183 bushels in this good overall field.

Soybean Summary: This is a drilled no-till field following corn with an average canopy height of 32 inches, but there was a lot of variability. The first node height was 3 inches and each successive node was 3 inches. The only disease was downy mildew and there was quite a bit of foliar feeding. This was a later planted field in the R3 with a population that was too high at around 200,000. There was some lodging out there already and that is 5 bushels right off the top of the yield. The field has fair yield potential. 


Preble County

Corn Summary: Excellent stand of 36-inch row corn with no disease or insect pressure at the R4 growth stage. The population was 25,000. There was a fair amount of tip dieback. There were very large ears, but not enough to be a top yielder. There was some root lodging and the estimated yield is 180 bushels. 

Soybean Summary: Planted with conservation tillage after corn with 38-inch canopy height and first node at 7 inches. There was little brown leaf spot in the lower canopy and a little leaf feeding. Field in the R4 stage with a final stand of 200,000. Overall good yield potential.

Butler County

Corn Summary: Dry conditions here. We had very weedy and dry with potash deficiency showing up and generally low fertility. Ear fill was poor and highly variable in the poor to fair field. Heaviest weed pressure of the tour. Yield estimate was 164 bushels.

Soybean Summary: This was 7.5-inch no-till field at 165,000 population. There were some grasshoppers and little disease in the R4 stage. Good yield potential here.





Warren County

Corn Summary: Looked like corn after corn with conservation tillage. It was a late planted field at R2 blister stage and green silks. Disease pressure was very low, as was insect pressure. The plants were over 12 feet tall and there was high ear set. There was a 31,000 population with estimated yield of 207, but it is hard to tell if ears will fill out fully at this early stage of development. An early frost or dry, hot conditions could limit the yield.

Soybean Summary: There was some lodging on the outside edge of the field. Canopy height was 36 inches and very uniform across the entire field. The first node height was 6 inches and 4 inches between node set. No real disease or insect pressure. Probably an R3 or R4 at 190,000 population. Good to excellent yield potential here and a nice field to end the tour.
