Romulo Lollato, associate professor of Agronomy, Kansas State University, presents “The Wheat We Grow Versus the Wheat We Could Grow: Quantifying and Assessing Causes of Wheat Yield Gaps in the US.” This presentation will summarize years of research quantifying and assessing causes of yield gaps in wheat using Kansas, the largest US winter wheat producer, as a case-study. Data presented will range from on-farm assessments of management and weather determinants of wheat yield, to detailed field experiments establishing the physiological determinants of yield and potential avenues to sustainably improve wheat production though optimization of genotype by management by environment interactions.
