No differences in sugar beet about nitrogen applications

A study conducted by Agricultural Research Service (ARS) scientists and their cooperators has dispelled a belief among some sugar beet growers that different sugar beet varieties require different nitrogen fertilization applications.

In the study, ARS agronomist Bart Stevens, at the agency’s Northern Plains Agricultural Research Laboratory in Sidney, Mont., and cooperators from the University of Wyoming found there are very minor differences in how eight sugar beet varieties commonly grown in northern Wyoming and southern Montana respond to nitrogen fertilization. Therefore, growers do not have to further complicate their fertilizer-management decisions by adjusting nitrogen applications for individual varieties.

However, some varieties are designed to produce bigger tops at the expense of sugar content, so growers should continue to choose appropriate varieties based on their overall management objectives.
