    The effect of different doses of fertilisation with phosphorus, potassium and nitrogen on seed yield of Dactylis glomerata L. of ‘Tukan’ variety

    The study was conducted at the Lipki Agricultural Experiment Station in Lipnik near Stargard Szczeciński on acid brown soil formed of light glacial sand on clay (5 Bw pgl : pgm), which is characterised by low content of humus on Ap level (1.57–1.59%) and clay particles (11.9–12.4%). The field experiment was set up in split-plot system in four replications, with an area of a single plot of 12 m2. The study included two factors: I – doses of phosphorus and potassium (P + K kg . ha–1): 60 + 120 and 90 + 180, II – doses of nitrogen (N kg . ha–1): 0, 40, 80 and 120. The experiment was established in 2010 by sowing Dactylis glomerata seeds of ‘Tukan’ variety (8 kg . ha–1) in spring barley harvested for grain. The study included two years of seed collection (2011 and 2012). The study determined plant density in the years of full use, number of generative shoots per plant, inflorescence length, number of spikelets and seeds per inflorescence as well as seed and straw yield. Biometric observations were conducted in 25 randomly selected inflorescences from each plot. Seed and straw yield was determined on the area of each plot during seed harvest. Dactylis glomerata of ‘Tukan’ variety was characterised by higher level of yields in the first than in the second year of seed collection. The obtained results indicate, that when establishing a plantation on light soil with companion planting in spring barley, it is advisable to use 120 kg N, 60 kg P and 120 kg K . ha–1. The increased phosphorus-potassium fertilisation (90 kg P and 180 kg . ha–1) did not change the studied morphological features of plants (number of generative shoots per plant, length of inflorescence, number of spikelets and seeds per inflorescence), while fertilising with nitrogen in doses of 40, 80 and 120 kg . ha–1 had a positive effect on increasing the above mentioned features.

    Feasibility of using Festuca arundinacea for regeneration of grasslands by means of full cultivation method on organic soil
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Czyż, Henryk; Jänicke, Heidi; Kitczak, Teodor; Bury, Marek; Department of Soil Science, Grassland Science and Environmental Chemistry, West Pomeranian University of Technology, Szczecin; Department of Soil Science, Grassland Science and Environmental Chemistry, West Pomeranian University of Technology, Szczecin; Landesforschungsanstalt fűr Landwirtschaft und Fischerei MV in Dummerstorf, Germany; Department of Agronomy, West Pomeranian University of Technology, Szczecin
    The study was carried out in the Randow river valley, on grassland belonging to the farm – Raminer Agrar GmbH & Co (Germany). Restoration of grassland located on organic soil, was carried out using the full cultivation method. The study included mixtures with the predominant participation of Festuca arundinacea. The assessment included the characteristics of floristic composition, sodding, and general appearance of meadow sward, level of yielding, and uniformity of biomass production during the growing season. The average results from the years of research (2012, 2013 and 2015) showed that the applied mixtures were similar in terms of yield, although the mixture of Festuca arundinacea with Dactylis glomerata – 50% each, and the mixture of Festuca arundinacea and Lolium perenne – should be distinguished. Of the studied varieties, Festuca arundinacea (‘Lipalma’, ‘Kora’, ‘Hykor’, ‘Fawm’), the greatest production potential characterized the Hykor cv. Festuca pratensis and Phleum pratense appeared to be less useful for multi-cutting management. Overall results show considerable usefulness of Festuca arundinacea in mixtures with Dactylis glomerata, Lolium perenne and Festulolium for the regeneration of grassland on organic soils
