Tall fescue and Italian ryegrass: an ideal mixture for intensive cutting management

Abstract
We established a trial in 2009 to compare the agronomic performance of tall fescue (Festuca arundinacea, Fa) with Italian ryegrass (Lolium multiflorum, Lm) growing in monoculture and in different mixtures of both species. Mixtures differed in the ploidy of the Italian ryegrass component (diploid vs. tetraploid) and the contribution of both species to the mixtures (1/4 or 1/8 of Lm seeds on a number base). Five cuts were taken in both 2010 and 2011. N-fertilization was around 300 kg N ha–1 per year. Dry matter (DM) content and botanical composition and feeding value were determined at each cut. Lm outyielded Fa in the first year after sowing but Fa outyielded Lm in the second year. In one of the mixtures, transgressive overyielding occurred in both years. The proportion of Fa in the DM yield of the mixtures was initially much lower than the sown proportion but increased gradually. We conclude that mixtures of Fa and Lm are particularly suited for an intensive cutting management.
