Most of the nitrogen fertilizer is applied to sugarbeet fields
in southern Idaho before planting. During the early stages of
plant growth the soil and fertilizer N is subject to leaching because
the NO₃-N concentrations in the soil usually are higher
than later in the season. The rate of N uptake in this area, under
conditions where N does not limit plant growth, increases rapidly
beginning early in June, reaches a peak early in July, and begins
to decrease in late July. If inadequate N is available to meet
crop needs then the addition of N fertilizer just prior to the
period when the demand rate increases should increase the efficiency
of sucrose production and N fertilizer use.

The practice of supplemental, midseason application of N in
irrigation water is increasing in southern Idaho. It is not known
whether this practice is resulting in more efficient use of N fertilizer,
increasing yields, or whether or not midseason applications
have an adverse net effect on sucrose production. The objective
of this study was to evaluate current N fertilizer practices
and the effect of irrigation management on root and sucrose
yields. Major emphasis was placed on the effects of N and irrigation
management on petiole NO₃-N concentrations to refine
the use of petiole analysis as a diagnostic tool in managing N
