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.

In a collaborative effort with Kansas State University, The University of Nebraska-Lincoln, and The Ohio State University, Purdue University is looking for Indiana farmers to participate in a multi-state survey that examines farmer’s views and approaches to on-farm research.

n this episode, Shaun and Dan discuss how corn is no longer king in Indiana or the US after USDA’s Prospective Plantings report last week showed that farmers will plant more soybean acres than corn, and tips for those planting beans on beans.
MULTI–YEAR SUMMARY OF CORN RESPONSE TO NITROGEN FERTILIZER This report summarizes corn yield response to fertilizer nitrogen (N) rate in field–scale trials conducted around the state of Indiana since 2006. These results are applicable to N management programs that use efficient methods and timings of N fertilizer application. The Agronomic Optimum N Rate (AONR) represents the total amount of fertilizer N (including starter N) required to maximize yield, but not necessarily profit. The AONR in these trials varied among regions of the state from about 211 to 254 lbs N / ac, depending partly on soil organic matter and soil drainage characteristics. At five Purdue Ag. Centers where we conducted paired trials of corn following soybean (corn/soy) and corn following corn (corn/corn) from 2007 to 2010, the average AONR for corn/corn was 44 lbs greater than for corn/soy while average corn/corn yields were 18 bu / ac less than the[Read More…]
