Název v původním jazyce

Effects of nutrient availability on performance and mortality of Rumex obtusifolius and R. crispus in unmanaged grassland

Popis výsledku v původním jazyce

Several authors record high mortality of the weedy species Rumex obtusifolius in unmanaged grasslands, but there have never been any studies on how the performance and mortality of R. obtusifolius and R. crispus are affected by different nutrient availability in unmanaged temperate grasslands. To investigate this question, we established a seedlings transplantation and fertiliser experiment on unmanaged Dactylis glomerata grassland in Czech Republic. We monitored plant height, number of leaves per plant, fertility and mortality of transplanted R. obtusifolius and R. crispus plants, from 2008 to 2011, in an unfertilised (U) and a fertilised (F) treatment (manure applied in 2008 at the rate of 200 kg of nitrogen, 42 kg of phosphorus and 230 kg of potassium per ha). In 2010, taller plants of both species were recorded in treatment F than in treatment U, but there was no effect of treatment on the number of leaves. In 2010, fertility for both species was 50% in treatment F, but only 20%
