PhD Student Yue Zhao and Professor David Hennessy recently published in Agronomy Journal. Zhao and Hennessy co-authored the article "Information Conveyed by Management Zones and Optimal Soybean Seeding Rate" with Laura E. Lindsey and Alexander J. Lindsey of The Ohio State University and Maninder P. Singh of Michigan State University. The article constructs an economic conceptual model for evaluating information conveyed by variable rate seeding management zones. Results show that management zones in four out of 10 trials do not display statistically significant differences in marginal seed productivity.
