Overall, I believe we are sitting on a good corn crop with a lot of potential to maximize grain fill and test weight.

 

Crop Conditions - Eastern Indiana

  • As of August 19: Corn crop ranges from R2-R5 development stages in much of eastern Indiana.
  • Soybean crop growth stages range from R3-R7.
  • Early season rain events meant sporadic planting windows for both corn and soybeans.

Corn

  • GDU, solar radiation and annual rainfall all are tracking above the 10-year average.
  • Foliar diseases set in early, stalled out near pollination, and are now progressing aggressively as we move into later reproductive stages with ample moisture and cooling temperatures. 

Soybeans

  • Crop will be variable and largely based on planting date and early-season stress mitigation.
  • Variable planting conditions and excess rains led to poor early root development in eastern clay-based soil textures.
    • Result - decrease in nodulation and late-season nitrogen fixation.
  • Late season Phytophthora, SDS and other root pathogens were more predominant from early season stress.

Extreme Weather in July

  • For corn planted in April to mid-May: Major storms, cool temperatures, and rapid growing conditions led to excessive silk production:
    • Some sporadic kernel set during pollination.
    • Results were uneven kernel fill.
    • Central Indiana was most affected.

'Highlighter Green' Soybeans

Early season stress in soybean root development leads to poor root inoculation

  • Early season stress in root development leads to poor root inoculation.
  • Nutrient demand during reproductive stages peak and stressed areas begin to show.
  • Early planted beans can have more nodes and thus require more N from rhizobium.

As of August 19: Corn is in the R4/ R5 stage. Soybeans are at ~R5 for most of the area.

 

Crop Conditions - South-Central Nebraska

Weather

Early season heavy rain events made emergence and stand establishment particularly challenging in many areas. Several washouts occurred with an April 25/26 rain event in south-central Nebraska.

Soybeans

  • Soybean seed treatments really flexed their strength this spring with stand establishment.
  • Dectes stem borer is prevalent in soybean fields.

  • The environment has been favorable for Sclerotinia white mold development.

Corn

  • Lack of rain in July with the onset of heat has really taken its toll on dryland crops.
  • Areas have experienced some pollination challenges.

  • Bacterial leaf streak progressed aggressively early.
  • The main concerning disease in the south-central part of the state is southern rust.
  • Northern corn leaf was discovered in early July.
  • We are watching out for Goss’s wilt as conditions have been conducive.

Summer Hail Event

Multiple rounds of hail in June and July devastated a large number of corn acres, and left others relatively beat up. Some replant did take place, but those crops are behind as they were planted in July.

Just as in corn, several soybean fields were impacted by hail in June and July. Recovery has been better than in corn due to the timing of damage but yield loss has occurred.
