1. Nitrogen Response of 2-Row Barley in North DakotaIn about 2019, the major malting barley buyers moved from 6-row barley cultivars to 2-row barley cultivars. The N response of 6-row barley was well-established, however, little local data regarding 2-row cultivar N response was available. A 2-year study was conducted in North Dakota on two sites, using two cultivars at each site. Rates of N from 0 to 160 pounds N per acre were imposed on each cultivar. One site was in a long-term (30+ years) no-till system, while the other site was in a transitional... A. Wick, D. Franzen, B. Goettl |
2. In-season Changes of Soil Mineral Nitrogen with Nitrogen Fertilizer and Nitrification Inhibitor in CornUnderstanding the role that soil mineral nitrogen (SMN) plays in the growth and productivity of corn is crucial. Nitrogen (N) demands vary during the growing season, and maintaining a sufficient amount of N in the form of ammonium (NH4+), or nitrate (NO3-) during the peak times of plant N uptake can help support high yields. The objective of this study was to assess changes and the supply of soil mineral nitrogen during the growing season in corn under field conditions in Kansas. This study was... P. Morinigo, D.

3. Recent 2-Row Malting Barley Nitrogen Rate Revision for North DakotaAs the demand of two-row malting barley (Hordeum vulgare L.) increases, having sound nitrogen (N) recommendations is increasingly necessary. Not only does N play a role in grain yield, but it may also significantly impact grain malting characteristics including protein, plump, and test weight. To determine the impacts N rate and N availability have on two-row malting barley, two experimental sites were established in both Spring 2020 and 2021. The experiments were organized as a randomized... D. Franzen, B. Goettl |
4. Optimizing Nitrogen Inputs in Barley Production in Idaho, Montana, and North DakotaNitrogen (N) management plays a critical role in balancing yield and malting quality of two-row spring barley (Hordeum vulgare L.) grown in the Northern Great Plains. In 2025, a field experiment was conducted across seven locations in North Dakota, Montana, and Idaho to evaluate the effect of N fertilizer source on barley yield, protein, and kernel plump. Treatments included the commercially available N sources urea, enhanced efficiency urea, urea ammonium nitrate, calcium ammonium... B. Goettl, . Souza, J. Spackman, J. Jensen |
