Last week, @PurdueCorn, assistant professor of corn production in @PurdueAgronomy, spoke with @WISHNews8 about @LifeatPurdue's innovative corn research and how it helps identify the needs of Indiana’s farming community. 🌽
Thank you WISH-TV for visiting our fields, harvesting plots and labs to get a behind-the-scenes look at how our faculty and students are turning research into meaningful insights for farmers.

Research trial harvest is off and running.
@PurdueAg @PurdueExtension @PurdueAgronomy @INCornFarmers
Following severe August flooding in parts of Indiana, ear rots and mycotoxin risk are important considerations as harvest gets underway.🌽

August storms in East-Central Indiana caused flooding and wind damage, with water above corn ears in some areas. Dr. Dan Quinn observed multiple ear rots and premature kernel sprouting (vivipary) in submerged ears.
🚨 New from The Kernel Lab! 🌽
Can narrower rows help when pushing seeding rates?
20-in (51-cm) rows enhanced yield at 3 of 4 site-years, and the response to seeding rate was more pronounced under narrow spacing at two site-years.

New from Crop Protection Network: research-based guidance on hail injury and fungicide decisions in corn, co-authored by CORN Network member Dr. Dan Quinn. 🌽
Fungicide is often considered after hail injury to corn due to the plant health statements present on many fungicide labels coupled with the natural desire to take action following a hailstorm.
An Overview of Hail Injury and Fungicide Use on Corn provides info to evaluate the potential benefits of fungicide application, and make the most profitable management decisions following hail injury in corn in upcoming growing seasons.

Congratulations to Dr. Dan Quinn on this well-deserved recognition!
Proud to see his work and impact in corn research and Extension recognized! 👏
Congrats to @PurdueAgronomy's @PurdueCorn, named the Indiana Corn Marketing Council’s Extension specialist in agronomy!
The @INCornFarmers's honor recognizes his leadership in corn research, Extension, education and his commitment to farm-based research, advancing Indiana agriculture. 🌽

🌽 Timing matters when managing foliar diseases in corn.
Drs. Daniel Quinn and Darcy Telenko discuss how well-timed fungicide applications can extend grain fill, increase kernel weight, and ultimately contribute to higher yields.

Immense flooding, waterlogged fields, wind snap - and questions about yield effects this late in the season.
@PurdueExtension specialists are here to find answers. Click the link to let us know how your fields were affected and if you're interested in having your fields monitored for the rest of the season.

🚨🚨 Calling all Indiana Farmers, Consultants, and Advisors. Please help us out and take a minute to fill out this short survey to help quantify recent rainfall and flooding impacts on crops in the state. Please share also.

Earlier this week, Dr. Dan Quinn shared ongoing research on nitrogen loss and management during the Pinney Purdue Agricultural Center Field Day.
The discussion covered common N loss mechanisms and research evaluating nitrogen inhibitors.
Thanks to everyone who joined us!🌽

Another thing to consider this year on top of all the rainfall we have had is the persistent cloudy days and lack of sunlight. Here is a snapshot of solar radiation data over the last 3 weeks in central Indiana in comparison to the last 5 years.

🌽Putting crop scouting skills to the test!
Last week, The Kernel Lab joined the Indiana Youth Crop Scouting Competition.
At our station, students tackled corn growth staging, potential crop injury and yield impacts, and grain yield estimation.

Introducing Dr. Chad Lee. His work focuses on corn and small grain production, including tillage systems, cover crops, crop rotations, and regenerative agriculture practices.
More CORN Network members coming soon!
🌽How much defoliation can corn tolerate before yield declines?
This week we completed manual defoliation treatments with 33%, 66%, and 99% leaf removal in both short- and tall-stature corn hybrids.
This photo shows the 99% defoliation treatment at R1.

@seanblomgren did a phenomenal job of summing up this episode. What an awesome experience it was to sit down with Grad Students from @PurdueAgronomy & the @TheKernelLab. Very inspiring to know these great professors are helping train and educate the next generation! Remember the names of these students!!
The future of agronomy is in good hands.
Our new ep brings together convos with five @purdueagronomy grad students. From weed science to crop production, they are tackling today's challenges while preparing for tomorrow's
