Interpretive Summary:

Technical Abstract: The western United States has experienced widespread drought in the past several decades in areas that already receive low rainfall. Research on irrigation and nitrogen management will play a key role in managing crops to meet stakeholder needs of yield and quality in this environment. Research looked at nitrogen application rates and timing of the final irrigation for the season. Irrigation ending at the soft dough crop stage maximized most yield and quality parameters where an additional irrigation had little effect on most measured factors. At the highest levels of added nitrogen, protein was increased to levels above those appropriate for malting and brewing. The results of this study provide evidence of the impact of irrigation cutoff timing and nitrogen management on grain yield and quality and malt characteristics that are critical for establishing appropriate fertilizer-N recommendations and irrigation management strategies in malting barley.
