Seed corn represents the single most expensive variable input cost for Indiana corn growers (Langemeier et al., 2019) and so choosing the most economical seeding rate is important for maximizing that dollar return to seed at harvest time.

Purdue Extension and Hoosier Ag Today have teamed up for a new podcast to provide timely, relevant and credible agronomic insights to listeners. Purdue Crop Chat features extension corn and soybean specialists Dr. Bob Nielsen and Dr. Shaun Casteel from Purdue.
Forecasts for freezing or near-freezing temperatures when late-planted fields of corn are not yet mature (i.e., not yet at kernel black layer) are naturally concerning to farmers and the grain markets.
The occurrence of severe photosynthetic stress (severe drought, extreme heat, severe nutrient deficiency, severe foliar disease) during or shortly after pollination in corn often results in poorly filled ears due to incomplete pollination or abortion of young kernels.
Seems like every year some fellow walks into the Chat ‘n Chew Cafe carrying an odd-looking tassel that is part tassel and part ear to show off to the guys over at the corner table.
Areas of Indiana have been exceptionally dry since early July.
Serious crop stress during the grain filling period of corn increases the risk of stalk rots and stalk lodging (breakage) prior to grain harvest.
Corn is often harvested at grain moisture contents higher than the 15% moisture typically desired by grain buyers.
Droopy ears are cute on certain breeds of dogs, but droopy ears on corn plants prior to physiological maturity are a signal that grain fill has slowed or halted.
Given the near record late planting of the 2019 Indiana corn crop and the continuing agony of delayed development of the crop, much of the coffeeshop talk down at Cecil’s Corner Cafe in recent weeks has centered on the risk of the late crop not maturing before a light frost damages the crop or an outright lethal freeze (28F) kills the crop.
