The influence of nitrogen fertilisation on the occurrence of couch grass (Elytrigia repens (L.) Desv. ex Nevski) in mowed grasslands of the alliance Arrhenatherion

Original language 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.
