Persist Forage Yields

CROSSVILLE, TN 2007-PRESENT:

In the fall of 2007 a forage trial study was planted at Crossville, TN. Irrigation was applied only at time of establishment. 60# of N was applied at green-up. Another 30# of N was apppied both after first cutting and in early Sept.

SUMMARY:

While statistically equal, note that Persist was second the first year and then first the second year of the trial. We would expect to see this trend of Persist rising to the top continue over subsequent years.

SPRING HILL, TN 2007-PRESENT:

In the fall of 2007 a forage trial study was planted at Spring Hill, TN. Irrigation was applied only at time of establishment. 60# of N was applied at green-up. Another 30# of N was apppied both after first cutting and in early Sept.

SUMMARY:

Very similar results were found in Spring Hill as in Crossville: Persist was second the first year and then first the second year of the trial. We would expect to see this trend of Persist rising to the top continue over subsequent years.

GREENVILLE, TN 2008-PRESENT:

In the fall of 2008 a forage trial study was planted at Greenville, TN. Irrigation was applied only at time of establishment. 60# of N was applied at green-up. Another 30# of N was apppied both after first cutting and in early Sept.

SUMMARY:

This trial is only one year old, and therefore the evaluators didn't see any statistical difference yet in the varieties. That said, we are pleased to report the highest numeric yielding variety was Persist. The details of the data showed the difference came in the second and fourth cuttings.

MILAN, TN 2008-PRESENT:

In the fall of 2008 a forage trial study was planted at Milan, TN. Irrigation was applied only at time of establishment. 60# of N was applied at green-up. Another 30# of N was apppied both after first cutting and in early Sept.

SUMMARY:

While only one year old, this trial already showed performance differences amongst the entries. w\We are pleased to report the highest numeric yielding variety was Persist. This location had only two cuttings.

KNOXVILLE 1989-94:

In the fall of 1989 a forage trial study was planted at Knoxville, TN where dry mater yield data, by individual cutting date was obtained for five years. The test included Persist (called Syn-2 at the time), and six commercially grown cultivars.

SUMMARY:

Yields of Persist exceeded that of the mean every year. Of particular significance was its superior performance in the last two years of the trial - indicating longer persistence than the other cultivars. Additionally, Persist was almost always the highest yielding variety during the last two or three cuts.

INDIVIDUAL YEAR RESULTS:

If you are really interested in how Persist pulls away from the pack over time, scan through the next five tables and notice its performance compared to the other varieties in the trial. Also take note of the later cuttings. Persist is almost always on top!
