General Stats
Soil Stats
Methodology
Eight strips of Asgrow 18×9 were planted at 220K and 160K across a hilltop on May 21, 2018 to see if increasing seeding rates on upland areas increases yield.
Results
We have seen instances where increased seeding rates on upland positions can increase yields. However in this trial, increasing the seeding rate above normal did not significantly increase yields on upland positions. A yield difference of 1.14 bu/ac would be required for the yields be to significantly different at the 90% confidence level.
