Static range nitrogen management in northwest U.S. sugarbeet production.

Abstract

Nitrogen (N) management is important in sugarbeet production due to effects on yield and quality. Evaluation of recent and past research data from the Northwest U.S. production area shows that using a static range N management (SRNM) approach better matches  sugarbeet N needs than currently used the YGNM approach. The SRNM approach uses a range of fixed N supply independent of yield goal.  The term “range” is used due to slight variations in required N supply due to soil types, climate, and other fixed factors. This paper will provide evidence for a shift from a YGNM approach to a SRNM approach.
