Technical Abstract: Nitrogen management is an important management factor in row crop production. In sugarbeet production it is especially important due to decreased profits associated with under and over supply of N relative to crop requirements. Under supplying N greatly affects root yield, and over supplying N results in increased root impurities (decreases sucrose extraction efficiency) and decreased sucrose content. Much research has been conducted over time to determine optimum N supplies for sugarbeet in various climates, soils, and management practices. One measure of N requirement or efficiency for sugarbeet production is the lbs of N needed to produce a ton of beets (Nr). This paper seeks to highlight changes in N use within the U.S. sugarbeet production and the Nr values determined from studies conducted in the U.S. sugarbeet production areas over time.
