Description
A trial was carried out at Perugia (Central Italy) in 1972/ 197 5 in order to gain information on the seasonal productivity and persistence of 24 varieties of Dactylis glomerata, Festuca arun-' dinacea, and Lolium perenne. The data on persistence, measured as ground cover, show clearly that local types are more persistent than foreign ones. The impact of the choice of varieties is not equally important for the three species; it is very important in Lolium perenne, it is still important in Dactylis glomerata, but its seems irrelevant in Festuca arundinacea. The dry matter yield of all the three species is concentrated in spring with an approximate 70 % of the annual yield while in autumn it reaches only 17%; in winter and in summer, with negligible values of 4 % and 7 %, respectively, there are two impressive growth gaps. This pattern is common to all the varieties so that attention should be extended to other forage plants.
