    The aim of the study carried out on the basis of a field experiment was to compare results obtained during cultivation of winter triticale in the organic and conventional farming systems. Comparing these two systems (organic with conventional), changes in the content of macroelements (phosphorus, potassium, calcium, magnesium), and microelements (manganese, iron, zinc and copper) were analyzed in the triticale grain. The study involved four triticale varieties: Benetto, Cultivo, Grenado, and Moderato. The field experiment was performed in 2010–2011 at The National Research Institute for Fisheries Affairs Mecklenburg – Vorpommern in Gulzow, Germany. Grain of all triticale varieties grown in an organic systems contained more phosphorus and magnesium. Compared tillage systems did not differentiate calcium and potassium in grain of triticale Benetto, Cultivo, Grenado, and Moderato varieties. No relationship was found between the total content of phosphorus, calcium and magnesium vs. cultivars. The total potassium content in triticale grain was differentiated by the varietal factor. The triticale grain of all tested varieties (Benetto, Cultivo, Grenado, and Moderato) grown in organic system was characterized by higher – by ten or so per cents – iron, zinc, manganese, and copper contents as compared to the conventional systems.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Sobolewska, Magdalena; Pużyński, Stanisław; Dojss, Dariusz; Hury, Grzegorz; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland; Grupa Azoty Zakłady Chemiczne „Police” S.A., Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland
    A wide range of multicomponent fertilizers, often with similar chemical composition, differs in the quality and digestibility of nutrients and price. The paper compared the effect of mineral multicomponent fertilizers from Polish and foreign producers on changes in the content of macronutrients in soil during sugar beet cultivation. The study also analyzed the effect of varying doses of fertilizers used. Fertilizers used were characterized by the following composition of NPK(S): two Belarusian 8–20–30, Russian 7–8, 19–20, 29–30 and Polish 6–20– 30(7) – Polifoska 6. The experimental plant was sugar beet of NATURA KWS cv., normal-sugar type. The soil on which the experiment was carried out was characterized by low abundance of available potassium and medium available phosphorus and exchangeable magnesium. The experiment was carried out in 2014–2017 in Lipnik. The study compared two factors: 1st factor – 4 multicomponent mineral fertilizers (two Belarusian, one Russian and Polifoska). 2nd factor – 3 doses of fertilization (minimum, optimum, maximum, which amounted to 2.5, 5.0 and 7.5 dt per hectare, respectively. Fertilization with multicomponent fertilizers did not have a significant impact on changes in the pH of experimental soil. In the experiment carried out, there was no difference in the performance of tested multicomponent fertilizers: Belarusian, Russian and Polish, regarding changes in the content of available phosphorus as well as available and exchangeable magnesium in the soil. The use of different doses of multicomponent fertilizers resulted in a significant increase in the content of available potassium and exchangeable magnesium in the soil, and the available phosphorus after using the highest dose of fertilizer.

    The 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’.

    Estimation of the Selected Winter Wheat (Triticum Aestivum l.) Varieties Cultivated in Organic and Conventional Crop Production Systems
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Łysoń, Ewelina; Biel, Wioletta; Sobolewska, Magdalena; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin, Poland; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin, Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland
    Four winter wheat (Triticum aestivum L.) cultivars (Akteur, Adler, Discus, JB Asano) derived from organic and conventional production systems carried out in 2010–2011 at Gülzow (Germany) were evaluated. The wheat samples were analysed for content of dry mass, protein, fat, crude fibre, total carbohydrates and fibre fractions (NDF, ADF, ADL, HCEL, CEL). Grain originated from organic system had on average the crude protein 27% lower than that from conventional one (p < 0.05). It was found, that the winter wheat grain from organic system contained the higher level of total carbohydrates (p < 0.01) and crude fibre than that from conventional one (p < 0.05). The examined cultivars also significantly differed in the content of crude fiber and dietary fiber fractions. The conducted research did not allow an unequivocal determination of the crop production system that would have more beneficial influence on nutritious value of winter wheat grain.

    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.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Sobolewska, Magdalena; Stankowski, Sławomir; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin
    The research material were cultivars of winter wheat grain from field experiments conducted in 2009–2010 from the National Research Center of Mecklenburg and Western Pomerania (LFA) in Gulzow. The first factor was a system of farming (conventional, ecological) and the second factor was the cultivars of winter wheat (Akteur, Adler, Discus i Hermann). Determined physical properties of grain, quality properties and rheological properties determined on farinograph. The use of conventional and organic cultivation system had no significant effect on the physical properties of wheat grain. Winter wheat grain obtained from conventional cultivation system characterized by a better quality than a grain from ecological system. Significantly higher values were obtained for crude protein content, gluten content, gluten softness and rate of sedimentation except for the falling number and index gluten. Using the conventional system obtained a better farinograph properties compared to the ecological. The exception was the waterabsorpsion for which there wasn’t significant differences. The best quality of grain and flour characterized by a cultivar Akteur and Adler but the worst cultivar Hermann.
