Brief Project Summary:

Globally, soybean is the largest source of both animal protein and vegetable oil that provides a variety of nutrients (N, P, K) and essential elements (Fe, Zn, etc.) that are very important for animal and human nutrition. A recent meta-analysis study has demonstrated that newer, high-yielding soybean cultivars, show decrease of 18 and 13% in seed P and K concentrations compared to older soybean cultivars, respectively (Balboa et al., 2018). In addition, wheat and soybean studies have observed that although newer cultivars always show higher yield, the micronutrient concentration (Fe, Zn) in the grains is significantly decreased (Garvin et al., 2006; Fritschi, personal communication). A decrease...

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
