Seeding Rate/ Varieties/ Row Spacing, Low Yield
One strip of Pioneer P16A49X was planted at 100K and 145K seeds/acre on May 19.
Decreasing the seeding rate from 145K to 100K increased soybean yield by 3.43 bu/ac. However, since there was only one replication, no statistical analysis could be performed to test for differences between treatments. Further research is needed to determine if yield was significantly different.
Funding for this research project was provided by the South Dakota Soybean Research and Promotion Council. The authors would also like to thank the soybean producers who participated in this project.
