Profile

ROSSERA is a very interesting, on the basis of performance, persistence and forage quality, diploid and late Perennial ryegrass variety. This is proven by official variety testing in the Netherlands, Germany and France. ROSSERA indicates great yield results under grazing and cutting. Moreover the variety achieves a high persistence and a good sward density. In the DSV trials ROSSERA was identified with a high digestibility of the organic matter. Combined with the high dry matter yields in all cuts ROSSERA produces outstanding energy yields per hectare.
