Abstract

Sugarbeet (Beta vulgaris L.) root quality has decreased
since the early 1950's in most sugarbeet-growing
areas (2). This decrease is generally associated with increased
nitrogen (N) fertilizer use which results in decreased
sucrose concentration and increased impurities in
the roots (13). Decreased root sucrose concentration with
N application is generally attributed to the tops becoming
the dominant photosynthate sink at the expense of the
roots (12). Increased impurities may result from many
factors, but are generally associated with higher N uptake
that increases the nonsucrose, soluble solids (2,
17).

Potassium (K) fertilization of sugarbeets is generally
not recommended in the intermountain areas of the western
United States because of the general K abundance in the
soils and irrigation water (6,8) and the lack of plant response
to K fertilizer in numerous unpublished field experiments.
Both K, an essential element for plant growth,
and sodium (Na), a non-essential element (28), are taken
up in large quantities by sugarbeets. The uptake rate and
total uptake of these elements depends upon N uptake,
plant growth, availability of these elements, year, and
genotype grown (1,8,15,17,30).
