Chrysanthemum coronarium L. is a weed of grain cereals also grazed by sheep. A research, aimed at the productive and qualitative characterization of C. coronarium, was carried out in Northern Sardinia (Italy) during 1993-96, in order to evaluate its introduction and role, as pasture species, within forage systems for dairy ewes. A sowed sward of C. coronarium has been evaluated both according to the Corrall method, with cutting every 28 days, and under undisturbated herbage accumulation. Corrall seasonal yield trends were different between years, due to the meteorological conditions and number of cuts. The forage yields were 3.5, 2.5 e 1.9 t ha** (-1), respectively, in the three years with high dry matter availability in winter and favourable crude protein and NDF contents, particularly in late spring. Under undisturbated accumulation, forage production were from twice to six times higher than those obtained using the Corrall method. First data about seed production and re-establishment have shown the self-reseeding capacity of this species. On the basis of the results obtained, C. coronarium appears very interesting as forage species and its introduction in forage chains is desirable
