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. Dan Quinn is currently an Assistant Professor of Agronomy and the Extension Corn Specialist at Purdue University. Dr. Quinn earned his B.S. and M.S. in Crop and Soil Science at Michigan State University and his Ph.D. in Plant and Soil Science at the University of Kentucky. His interdisciplinary research and extension program at Purdue works to improve the overall production, profitability, and environmental performance of Midwestern U.S. corn systems. Currently, Dr. Quinn’s research program includes studies examining yield physiology, agronomic management intensities, precision technologies, nutrient management, and cover crop use in corn production systems using large-scale and small-plot field research trials.
