Brief Project Summary:

Increased biomass production is the major driving force leading to greater nutrient accumulation within the plant. Dr. Steinke has documented similar biomass production (lb/A) from seeding rates as low as 50,000 seeds per acre up through 170,000 seeds per acre. Additional recent research from Illinois and Wisconsin has highlighted the importance of season-long nutrient accumulation as grain tissues remobilized a majority percentage of N, P, Cu, and S to developing seed during grain fill. Much of the late-season nutrient uptake and partitioning to grain comes from the soil, emphasizing the importance of sufficient soil nutrient resources in the later reproductive growth stages to prevent...

Information And Results
Project Deliverables

Measureables will vary by individual study but may include 1) plant height and SPAD readings at V3-4 and R5, 2) tissue sampling at R1, 3) canopy coverage and biomass accumulation, and 4) grain yield and moisture. In-season or end-of-season videos providing field updates may also occur. To quantify differences in nutrient uptake and partitioning by seeding rate, three whole plant samplings will occur for project #1 and #2 above. All studies will be highlighted for summer research tours, discussed at appropriate extension meetings, and results posted at soil.msu.edu.

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.
