Excessive rainfall events (aka “goose-drownders”, “toad-stranglers”) that occur late in the growing season can cause flooding of rivers, creeks, and streams as well as ponded areas within fields distant from floodwaters.

In recent years, sulfur (S) deficiency has been diagnosed in corn, soybean, alfalfa, and wheat in the Midwest, including Indiana and Michigan.
Max air temperatures for central and southern Indiana averaged 89- and 90-degrees F, respectively for the week of June 12th, 2022 which measured 10% above the 30-year average. In addition, air temperatures of 96-degrees F and above were observed during the week and record max air temperatures for this point in the season were observed in multiple locations across Indiana. Unfortunately, similar high temperatures are expected for the week of June 20th, combined with minimal chances for precipitation. Therefore, as high temperatures continue to persist and soils begin to dry out, this begs the question of what will happen to the corn crop? And, should I be concerned? The good news is that corn originated from a tropical grass and has been observed to withstand temperatures upwards of 112-degrees F for short periods, with plant growth typically decreasing when temperatures exceed 95-degrees F (Thomison, 2016). Therefore, temperatures in the[Read More…]
Due to its relatively recent U.S. discovery and its ability to cause significant production and economic losses, tar spot is often a topic of angst and anxiety amongst corn farmers and agronomists in Indiana.
The corn and soybean planting season has been compressed significantly due to the frequent rain showers received during late April and May.
After a delayed start to our planting season, we were able to plant both corn and soybean across the state in record or near-record time during May. This coincided with some timely rains and hot weather.
Successful stand establishment of a corn crop relies on many factors, including the successful emergence of the seedlings in the first place.
Due to the cold wet weather we experienced in late April and early May, corn planted in April has struggled to emerge in many areas of the state.
Early planting favors higher yields, but does not guarantee higher yields.
Intensive study for more than 100 yr has resulted in a good understanding of corn’s (Zea mays L.) growth and development.
