The hybrid is a multi-cut crop suitable for green mass production, silage making, hay, and grazing. The period from emergence to flowering is 62–65 days. The plant reaches a height of 2.5–2.6 meters and is characterized by stem flexibility.

The variety possesses a high tillering capacity and rapid regeneration after cutting, which allows for up to three cuts per season. The plant is characterized by good protein content. For forage purposes, it is recommended to use it upon reaching a height of 90–100 cm, and maximum dry matter yield is provided when harvested at the grain maturity stage.
