Symposium--Understanding Yield Variability

Oral Session

ASA Section: Agronomic Production Systems

This symposium will provide a state-of-the-art update on how what we know about the causes for yield variability and its management. To improve the resilience and adaptability of crop production systems it is critical that we understand the causes and management practices designed to overcome these limitations.
