    Analysis of macronutrients content in winter wheat grain of spelt type (Triticum aestivum ssp spelta L.) depending on crop protection, seeding standards and variety

    The aim of the study was to evaluate the effect of crop protection and seeding ratio on the contents of macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium) in grain of two spelt cultivars: Polish ‘Rokosz’ and German ‘Schwabenspelz’. The field experiment was conducted in Czesławice in 2014–2015 on lessive soil developed from loess classified as good wheat complex and II bonitation class, slightly acidic. The plowing layer of the soil was characterized by a high content of available forms of phosphorus, potassium and average magnesium. Material for analysis consisted of winter spelt grain. The first experimental factor: winter spelt varieties; second factor: two seeding ratios; third factor: crop protection. The harvest was performed at full grain maturity stage. Content of three basic macronutrients in spelt grain: nitrogen, phosphorus and potassium, was varied for cultivars. Meanwhile two cultivars did not differ with the amount of magnesium and calcium in grain. ‘Schwabenspelz’ was more abundant than ‘Rokosz’ regarding to studied macronutrients. The increase of plant density resulted in significant reduction in the nitrogen content and increase in the amount of phosphorus in winter spelt grain. The amount of plant density did not affect the abundance of spelt grain in relation to metals included in macronutrients occurring at plants. The crop protection treatments of winter spelt did not impact on the macronutrients content in grain.

    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

    Impact of form and dose of nitrogen fertilizers on the technological value of spring triticale (x Triticosecale Wittm. ex A. Camus)

    The field experiment conducted in 2013–2014 at the Agricultural Experimental Station in Lipnik (53o42′ N, 14o97′ S), West Pomeranian Technological University in Szczecin, on light, good rye complex soil. The experimental material consisted of spring triticale grain of 'Nagano' cv. The first experimental factor was the type of fertilizer. Ammonium nitrate was used, ammonium and nitrate forms of nitrogen, as well as Sulfammo 30 N PRO, ammonium and amide forms of nitrogen. The second experimental factor was doses of nitrogen fertilization: 0 (control), 40, 80, 120 kg N . ha–1. Determined the selected physico-chemical quality traits of grain and farinographic properties of dough. No significant effect of the applied nitrogen fertilizer type and nitrogen fertilization dose was observed on: TGW, test weight, grain fraction, falling number and Zeleny index of the spring triticale grain,. The highest content of proteins were in grain of spring triticale fertilized with the dose of 120 kg N . ha–1. The increasing nitrogen fertilization increased the water absorption of flour and dough stability, while reduced the degree of dough softening. Sulfammo 30 N-Pro significantly improved the dough stability as compared to the ammonium nitrate. There were significant, positive correlations between: protein content in spring triticale grain and dough development time and its stability.
