Does Size Matter? Agronomic Management of New Short-stature Corn Hybrids
Recently introduced short-stature hybrids target to improve overall Midwest corn production and efficiency by reducing lodging potential, improving tolerance to narrower rows and higher plant populations, and expanding “over-the-top” input applications. However, agronomic management recommendations may need to be reassessed and updated in comparison to modern full-stature hybrids. This presentation will highlight ongoing research which examines both short-stature and full-stature hybrid responses to row spacing, seeding rates, nitrogen rates, and fungicide timings.

Dan Quinn
Dr. Daniel J. Quinn is an Assistant Professor of Agronomy and the Extension Corn Specialist at Purdue University. He earned his B.S. and M.S. in Crop and Soil Sciences from Michigan State University and his Ph.D. in Plant and Soil Science from the University of Kentucky. Dr. Quinn leads an integrated research and Extension program focused on improving corn productivity, profitability, and environmental performance across Indiana and the Midwest. His current work examines fertilizer management, hybrid types, crop physiology, agronomic management intensities, equipment technology, conservation cropping systems, and the use of precision and sensing technologies to enhance nutrient efficiency and yield stability. Since 2021, his team has conducted more than 150 field trials across Indiana and secured over $4 million in competitive and industry funding. In addition, he has delivered over 200 presentations to over 24,000 people, been invited to speak at 33 out-of-state and international conferences, authored 20+ peer-reviewed papers, and leads several regional and national collaborations advancing science-based corn management practices.
