Key Words: Water Management
It is crucial to increase water productivity, which is soybean seed yield produced per unit of seasonal water supply, to sustain soybean acreage and yields in Nebraska. The goal of this project is to develop an easy-to use framework that helps improve water use in Nebraska soybean production while maintaining, or increasing current irrigated or rain-fed soybean yields. The specific project’s objectives are to: • Define a benchmark for soybean water productivity based on the relationship between soybean attainable yield and total water supply; • Determine on-farm soybean water productivity; and • Identify combinations of management practices that increase water use efficiencies and soybean yields.
