1. Wheat Zinc Nutrition: Agronomic Biofortification That Delivers Yield and Better Grain NutritionLow Zn availability in calcareous soils is a common issue in the Canadian prairies, where much of the wheat is exported, making Canada one of the world’s largest wheat exporters. Globally, 19% of the population, mostly pregnant women, infants, and children, suffers from Zn deficiency, highlighting the need to enhance Zn bioavailability in wheat grain. Agronomic biofortification offers a promising strategy to improve grain nutrient density while optimizing plant health and development. While... M. Proulx, X. Gao |
2. Influence of Nitrogen Management and Precipitation on Sorghum Nitrogen Use EfficiencyGrain sorghum (Sorghum bicolor L. Moench) is a key crop in Kansas which can benefit from optimized nitrogen (N) management that enhances yield while minimizing N losses. Understanding the relationships among physiological efficiency (PE), recovery efficiency (RE), and agronomic efficiency (AE), as well as their interactions with climatic factors such as precipitation, is essential for improving nitrogen use efficiency (NUE). Experiments were conducted across five rainfed... M. Platero |
3. Season-long Tools for Effective Potassium Management in Arkansas Cotton ProductionKnowledge of how accurately soil testing and plant analysis identify nutrient-deficient soils and recommend the proper fertilizer rate is important to ensure farmers are profitable. However, critical tissue-potassium (K) concentrations have not been established for modern high-yielding cotton (Gossypium hirsutum L.) cultivars currently grown across the U.S. cotton belt. Likewise, limited research has investigated the window of opportunity to correct K-deficient cotton with in-season fertilization... G. Drescher, T. Roberts, M. Popp, N. Slaton, M. Ramos do prado, A.
