Plennosc lak trwalych bedacych zapleczem suszarni

Wydzielono cztery zbiorowiska roślinne i oznaczono ich skład botaniczny. Obliczono plon z hektara suszu wytwarzanego w suszarni gospodarstwa Bogusławie. Określono cechy i wykonano analizę podstawową składu suszu dla jego klasyfikacji. Najlepsze susze otrzymano z łąk zbiorowisk Alopecurus pratensis i Phleum pratense, gorsze ze zbiorowiska Elymus repens i najgorszy ze zbiorowiska Carex gracilis.

The study covered permanent meadows on organic soil situated at the Bay of Szczecin, Stepnica commune. Measurements were carried out in the period of 1995 - 1997 and aimed at determining the yield of green matter by means of random cuttings of 20 m² spots and yield of artificially dried grass of 8% moisture content. The meadow herbage was also studied to identify its botanical composition by means of botanical-weight analysis. The results show that the annual yield of green matter and artificially dried grass were greatly influenced by mineral fertilization, number of cuts and then by botanical composition of cuts and some weather conditions, especially precipitation and average temperature in early spring. The botanical composition of the meadows was a result of intensive utilization, soil properties and meadow menagement. The quality of artificially dried grass, i.e. the contents of total protein, crude fibre, carotene and mineral impurities depended mostly on the first cut harvesting date, weather conditions, and botanical composition of the herbage.
