Wzrost i rozwój wybranych gatunków traw z rodzaju Miscanthus uprawianych w warunkach klimatycznych Pojezierza Olsztyńskiego
Journal Title: Łąkarstwo w Polsce - Year 2015, Vol 18, Issue
Abstract
A field experiment was conducted in spring of 2007 in the Agricultural Experiment Station in Bałdy, owned by the University of Warmia and Mazury (NE Poland). The experiment had a completely randomized design with four replications. Plot size was 20 m2. Twenty seedlings of giant miscanthus (Miscanthus sinensis giganteus Greef & Deuter) and 60 seedlings of Amur silvergrass (Miscanthus sacchariflorus (Maxim.) Hack) were grown per plot, at the density of 1 plant per m2 and 3 plants per m2, respectively. The experiment was established on mineral soil (sandy silt) of quality class IVa. The aim of the study was to determine the effect of climatic conditions in the Olsztyn Lakeland on the growth and development of introduced species of C4 grasses. It was found that term drought accompanied by high temperatures in spring 2007 had a negative influence on the rooting and vigor of seedlings. Massive losses were noted in Miscanthus giganteus treatments. The results of this study indicate that under the climatic conditions of the Olsztyn Lakeland, the number of giant miscanthus seedlings should be increased to 2 per m2 of plantation area. Miscanthus sacchariflorus was more resistant to adverse climatic conditions than Miscanthus giganteus. The fertilizers used in the experiment had a significant positive effect on the growth of the analyzed miscanthus plants.
