    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.

    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

    Studies were carried out in 2003–2007 on the meadow with the community of Festuca rubra, on the rot soil proper. In the meadow experiment two factors were studied – the dose of nitrogen (0, 60, 120, 180 kg · ha–1) and the grass-leguminous mixtures of seeds, with different participation of Festuca pratensis and Trifolium pratens1 e (1 – without sowing – control, 2 – Festuca pratensis – 100% – 30 kg · ha–1), 3 – Festuca pratensis – 70% + Trifolium pratense – 30%, 4 – Festuca pratensis – 50% – Trifolium pratense – 50%, 5 – Festuca pratensis – 30% + Trifolium pratense – 70% 6 – Trifolium pratense – 100% – 18 kg · ha–1). Analysis of the floristic composition of sward showed that the proportion of Festuca pratensis increased when seed quantity and nitrogen dose were enlarged, but there was no such regularity in the case of Trifolium pratense. Its share declined independently of the factors of the experiment in the subsequent study years. Between used combinations of experimental factors, the most productivity in terms of dry matter yield were objects sawed with mixture – 70% Festuca pratensis and 30%, Trifolium pratense and Trifolium pratense alone, fertilized with nitrogen doses of 120 and 180 kg · ha–1. Feed of individual objects characterized by similar chemical composition. The concentration of majority of analyzed elements (N, P, K, Ca, Mg, and Cu, Zn, Fe, Mn) corresponded to the level recommended for a good feed. Only the content of zinc and copper fluctuated below the norm, but phosphorus and potassium – it greatly exceeded.

    The Response of Festulolium Braunii (K. Richter) A. Camus to the Amount of Seeds Sown and the Llevel of Nitrogen Fertilisation in Cultivation for Seeds
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Czyż, Henryk; Kitczak, Teodor; Faculty of Soil Science, Grassland Science and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland; Faculty of Soil Science, Grassland Science and Environmental Chemistry, West Pomeranian University of Technology, Szczecin, Poland
    The study was conducted in the years 2008–2011. Two factors were taken into account in the research: I – the amount of seeds sown: 9, 12 and 15 (kg · ha–1) and II – nitrogen dose: 0, 60, 90 and 120 kg · ha–1. The experiment was founded in the spring of 2008, with sowing with a nurse crop – spring barley, on brown soil of brown acidic subtype formed of light clayey sand of glacial origin – IVb soil valuation class. In the autumn of the year when the experiment was founded the following were applied – 80 kg P2O5 · ha–1, 80 kg K2O · ha–1 and 30 kg N · ha–1, and in spring – in the year of complete use, before vegetation, 40 kg K2O · ha–1 was applied and nitrogen fertilisation was replenished up to the amount assumed in the third factor of the research. The results of the study over Festulolium braunii of Sulino cultivar showed that on light soils it is possible to obtain an average seed yield of 13.5 dt · ha–1 – in the first year, 16.1 dt · ha–1 – in the second, and 15.3 dt · ha–1 – in the third year of yielding. The research revealed that when founding a seed orchard by companion planting with spring barley it was recommended to apply the amount of seeds sown of 15 kg · ha–1. On light soils the use of nitrogen fertiliser in doses of 60, 90 and 120 kg · ha–1 caused an increase in Festulolium braunii seed yield in the years of the study on average by 34.9, 46.3 and 53.3% respectively in comparison to the units fertilised only with phosphorus and potassium. The factors used in the research had also a favourable effect on the increased number of spikelets and seeds per inflorescence.
