New and emerging planter technologies have made the ability to manipulate and vary corn seeding rates across an entire field with impressive accuracy, precision, and ease. However, understanding the where, when, and how much of varying corn seeding rates can be challenging. This presentation will highlight both previous and new research examining corn yield response to varied seed rates, spatial seed rate responses, the driving factors between spatial responses, and the benefits and challenges of this practice. In addition, this presentation will highlight new research techniques and tools to further evaluate spatial seeding rate responses within your own fields and environments to help direct future variable seed rate applications for corn.

Speaker: Daniel Quinn, Purdue University

Biography: 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.
