In the Netherlands organic and conventional dairy farmers are taking an increasing interest in grass and red clover mixtures for ley pastures (cutting only). A constraint to the adoption of such mixtures is the persistency of the red clover (Trifolium pratense L.) varieties presently used in the Netherlands; Rotra, Barfiola, Violetta and Merviot. The latter being the most persistent under practical circumstances. Testing of red clover varieties in Switzerland showed a high degree of persistency of the so-called ‘mattenklee’ varieties such as Astur and Pica (Suter et al., 2004). We compared eight red clover varieties including 2 ‘mattenklee’ varieties in mixtures with perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.), and a mixture containing white clover and perennial ryegrass only. Red clover mixtures out yielded the white clover mixtures by 5.4 t dry matter (DM) ha -1. ULC 1715186 and Astur were the most productive red clover varieties. The development of the clover content of Astur showed that this variety scored highest on persistency.
