Above ground herbage yield and chemical composition of the understorey vegetation in a silvopastoral system in northern Greece
In the present research aboveground herbage yield and N, P, K, Ca and Mg concentrations in the understorey vegetation were investigated in a silvopastoral system in northern Greece. The experimental design was a split-split plot with three replications and included: three understorey treatments (Lolium perenne, Trifolium repens and control), two tree species (Acer pseudoplatanus and Pinus sylvestris) and two spacings (2.5m x 2.5m and 3.5m x 3.5m). During the early stages of establishment, the influence of trees on aboveground herbage yield and on chemical composition of the understorey vegetation neither by plant species or spacing was not significant. N and Ca concentrations were found significantly higher in white clover tissues.
