1. Independence of Yield and N-Rate, and Use of EONR in N Fertilizer Recommendations in North DakotaEvidence for the independence of N-rate and yield comes from the improved relationship of N-rate with relative yield compared to raw yield in corn, spring wheat and sunflower N-rate experiments in North Dakota. Relationships were also improved in corn by grouping experiments by regional location and whether the soils are high clay (>40% clay) or not, and discriminating between long-term no-till (6 years or more continuous no-till) or conventional till. In spring wheat, regional differences... D. Franzen, H. Bu, L. Sharma, E.C. Schultz, A. Wick, B. Goettl, M. Berti |
2. Integrating NDVI and Plant Tissue Analysis As Decision Support Tools for Nutrient Management in Winter WheatEfficient nitrogen (N) management is critical for improving winter wheat grain yield and protein content while minimizing costs and environmental risks. Remote sensing indices, such as the Normalized Difference Vegetation Index (NDVI) and physiological indicators, like flag leaf N content, have been proposed as predictors of crop performance that could support in-season N management decisions. This study evaluated the relationships between NDVI measured at multiple growth stages, flag leaf N at... J. Leiva, D. Ruiz Diaz |
