Illinois Yield Data
In 2004, five orchardgrass varieties were entered in a University of Illinois forage yields trial. The trial was seeded on April 3rd, 2004 on silty-clay loam in Urbana, IL. Fertilizer applications were 50 lbs of N 30 days before each harvest. While the 3-yr total for each variety is statistically equal, it is worth noting that Persist was the highest-yielding variety in the third year. If the trial had continued for multiple years, we would expect Persist to remain at the top of yield performance.
