Perennial grasses such as Festulolium may be of interest for biogas production. We investigated the effect of species composition and harvest strategy on biomass yield and methane potential in three field trials, established in Denmark in 2007, each with 2x2x2=8 treatments: Two cultivars of Festulolium were sown either with or without red clover (Trifolium pratense) and harvested either two or three times year-1. Treatments with and without red clover were fertilized with 250 and 350...
