Pozycja Open Access The effect of soil tillage system and nitrogen fertilization on baking quality of winter spelt cultivars(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Hury, Grzegorz; Stankowski, Sławomir; Makarewicz, Artur; Sobolewska, Magdalena; Biel, Wioletta; Opatowicz, Natalia; Department of Agronomy, West Pomerania University of Technology, Szczecin; Department of Agronomy, West Pomerania University of Technology, Szczecin; Department of Agronomy, Siedlce University of Natural Science and Humanities; Department of Agronomy, West Pomerania University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomerania University of Technology, Szczecin; Department of Agronomy, West Pomerania University of Technology, SzczecinThe material for investigation were grain samples obtained from an experiment conducted in 2009–2011 at the Agricultural Experimental Station in Lipnik, near Szczecin. The study compared 3 factors: two systems of soil tillage (reduced and conventional), 4 nitrogen doses (0, 50, 100 and 150 kg · ha–1) and 3 winter spelt cultivars (‘Franckenkorn’, ‘Oberkulmer Rothkorn’, ‘STH 12’). The quality and farinograph traits of grain, flour and dough were estimated. Soil tillage systems – reduced and conventional – practically had not effect on grain and flour quality. Significant difference was observed only for gluten content. Nitrogen fertilization influenced significantly most of the quality traits. The optimal nitrogen level was 100 kg N · ha–1. Only for gluten index and gluten weakening the highest values have been observed at control variant without nitrogen fertilization. There was no interaction between cultivars and nitrogen fertilization except for gluten index. Mean values of this trait for cultivars ‘Oberkulmer Rothkorn’ and ‘Franckenkorn’ was on the same level at different nitrogen dose. Gluten index for cultivar ‘STH 12’ decreased significantly at higher doses. The results of farinograph analyses indicate that cultivar with the best baking quality was ‘Oberkulmer Rothkorn’, while with the worst quality – ‘Franckenkorn’.Pozycja Open Access The effect of tillage system and nitrogen fertilization on nutritional value of winter spelt wheat cultivars(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Biel, Wioletta; Hury, Grzegorz; Jaroszewska, Anna; Sadkiewicz, Józef; Stankowski, Sławomir; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of the Food Technology, University of Science and Technology, Bydgoszcz; Department of the Food Technology, University of Science and Technology, BydgoszczThe field experiment was carried out at the Agricultural Experimental Station of the West Pomeranian University of Technology in Szczecin, in Lipnik near Stargard Szczeciński in 2009−2011. The experimental factors consisted of: tillage systems (simplified and plow), selected cultivars and strains of spelt (‘Frankenkorn’, ‘Oberkulmer Rotkorn’, ‘STH 8’, ‘STH 11’, ‘STH 12’), and nitrogen fertilization levels (control – 0, 50, 100, 150 kg N . ha–1). Material for the study included samples of grain obtained as an average for the experimental combinations. In samples of grain were determined the basic chemical composition and fiber fractions. The research indicates that there are opportunities to shape the size of nutrient levels, which determines the use of spelt grain in the food industry by agronomic factors. Higher nitrogen fertilization significantly increased content of total protein (154 g . kg–1). Cultivar and strain factor had significant effect on the content of total protein (154 g . kg–1), crude fat (19.3 g . kg–1) and crude ash (20.8 g . kg–1) as well as neutral-detergent (114 g . kg–1) and acidic-detergent dietary (33.3 g . kg–1) fiber fractions.Pozycja Open Access The influence of soil differentiation on chemical composition of sea buckthorn (Hippophaë rhamnoides L.) leaves as feed material(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Jaroszewska, Anna; Biel, Wioletta; Jurgiel-Małecka, Grażyna; Grajkowski, Józef; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, SzczecinDue to the fact that sea buckthorn leaves could be a supplement to animal feed and food products, the present research aimed at determining the content of such elements as nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, lead, cadmium, nickel and copper in sea buckthorn leaves as well as establishing the relation between the elements content and soil composition. The leaf samples were collected in June 2014 from wild sea buckthorn shrubs (Hippophae rhamnoides L. ssp. rhamnoides) localised in four spots in Szczecin Poland. The data concerning the content of macronutrients (N, P, K, Ca, Mg) and micronutrients (Fe, Mn, Zn, Ni, Cu, Pb, Cd) in leaves of wild sea buckthorn (Hippophae rhamnoides L.) indicate that the leaves can be considered good animal feed material, comparable to grass and legumes. The fact that content of lead and cadmium in wild sea buckthorn leaves do not exceed the accepted norms for these elements is an another argument confirming its usefulness as an animal feed material.
