Description	The occurrence of common couch grass (Elytrigia repens (L.) Desv. ex Nevski) in permanent grasslands was investigated during 2003–2009 by means of a small-plot trial. The experiment was carried out 390 m above sea level in the conditions of the Hruby Jesenik foothills. Four rates of fertilisation were applied: nil-fertilisation, P30K60, N90P30K60, and N180P30K60 (pure nutrients). The trial was managed with four levels of utilisation: intensive (4 cuts per year), medium intensive (3 cuts per year), low intensive (2 cuts per year) and extensive (1 or 2 cuts per year). Treatments without N fertilisation showed the lowest percentage ratio of couch in the swards (6.3 %, and 5.8 %, respectively; means of 2003–2009). The occurrence of couch in treatment N180P30K60 was 5.4 % in 2003 and 30.1 % in 2009. Increase in couch grass occurred as a response to nitrogen fertilisation, and it was most significant in extensively utilised grasslands. The occurrence of common couch grass (Elytrigia repens (L.)
