Early spring growth and medium late heading

TIRNA starts early in the spring with a heading mid May under French conditions - leaving a long period where the grass quality remains at a very high level.

Productivity with good persistency

TIRNA has a high drymatter yield at the level of the confirmed variety Dalita. The persistency is superior though the variety is classified as "Italian" type.

Good rust resistance

The level of rust resistance allows preserving palatability and the speed of regrowth.
