The influence of nitrogen fertilizer application on the occurence of couch grass
Original language description
The occurrence of common couch grass (quackgrass: 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 390-402 m above sea level in the conditionsof the Hruby Jesenik Mountains in the Czech Republic. The trial was managed with four levels of utilization: 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). Four ratesof fertilization were applied: nil-fertilization; P30K60; N90P30K60; and N180P30K60 (pure nutrients). Treatments without N fertilization showed the lowest ratio of couch in the swards (6.3%, and 5.8%, respectively; means of 2003-2009). The occurrence ofcouch in treatment N180P30K60 was 5.4% in 2003 and 30.1% in 2009. Increase in couch grass occurred as a response to nitrogen fertilization, and it was most significant in extensively utilised grasslands.
