Abstract

Typical of dryland, where fallowed wheat yields range from 15 to 45
Bu/A, neither yield nor protein responses to nitrogen (N) fertilizer are
consistent (2, 3, 4, 8). Workers at the Tetonia and Aberdeen Branch
Stations in Intermountain Idaho began trials as early as the 1940's, but
there were no unifying concepts that would allow projection of trial
results to individual farm fields. Therefore, few reports have been
published, although trials have continued to date (1, 5, 8, 9).

The purpose of this paper is to summarize and interpret the data
collected over the entire period. We identified the two following goals:

1. The summary should be based on established agronomic relations,
and

2. The results of the analysis should improve predictions of yield
and protein responses to N fertilizer.
