Brief Project Summary:

Many soybean planters being purchased by farmers today are equipped with the ability to vary the seeding rate as they go across the field. The idea of variable rate planting in soybeans may allow farmers to fine tune their plant populations based on management zones within a field. The foundation of the variable rate is that highly productive soils may produce adequate yields with lower plant populations and medium to poor productive soils may need higher plant populations to optimize yield. Previous studies with B&M Crop Consulting have shown an agronomic and economic improvement with variable rate soybean planting across management zones, but some environments seem to respond to higher...

Several plant measurements will be taken to help evaluate the seeding rate prescription by planting date and tillage.

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.
