Effect of Cutting Frequency on Species Richness and Dry Matter Yield of Permanent Grassland after Cessation of Grazing Management

Popis výsledku v původním jazyce

The effect of cutting regime with absence of fertilization was investigated on semi-natural grassland that was intensively grazed for more than 30 years before the experiment set up. The small-plot trial was studied during 2005-2011 using randomized plot design of treatments: (4C) – intensive (four cuts per year); (3C) – medium intensive (three cuts per year); (2C) – low intensive (two cuts per year); (1C) – extensive (one cut per year); (0C) – abandoned (control; without any management). Species richness significantly decreased in treatments 1C and 0C, where dominance of tall grasses (Poa pratensis, Dactylis glomerata, Elytrigia repens) was significantly higher. Bboth management and year significantly close influenced botanical composition and explained 23 % of its variability showing that weather condition and plant nutrition also should be considered. . Dry matter yields were found significantly lower in three-cut treatments than in two-cut treatments (5.56 t ha-1 and 6.22 t ha-1, respectively). I
