Pozycja Open Access Analysis of influence farming systems on chemical composition of four variety of triticale winter (xTriticosecale Wittm. ex A. Camus) grain(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Gibczyńska, Marzena; Dawidowski, Andrzej; Sobolewska, Magdalena; Jaroszewska, Anna; Lewandowska, Leokadia; Department of General and Ecological Chemistry, West Pomeranian University of Technology, Szczecin; Grupa Azoty Zakłady Chemiczne „Police” SA, Police; Department of Agronomy, 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, SzczecinThe 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.Pozycja Open Access Analysis of the content of macro- and microelements in the leaves of sea buckthorn (Hippophaë rhamnoides L.)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Jaroszewska, Anna; Biel, Wioletta; 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 Chemistry, Microbiology and Environmental Biotechnology, West Pomeranian University of Technology, SzczecinSea buckthorn is used in the world primarily for its high nutritional value and unique healing properties. It is a plant with a small climate and soil requirements. The study was conducted to determine changes mineral compounds in leaves of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), depending on the substrate type and the passage of time and assessment of the potential for sea buckthorn growth on saline and degraded soil. The determined the amounts of nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, sodium, molybdenum, chromium, lead, and cadmium. Shrubs of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), of which leaves were collected in June 2015, were located in four sites in Szczecin. The soils, on which sea buckthorn bushes grow are alkaline. The different sites of the growing shrubs of sea buckthorn (Hippophae rhamnoides L.) and the applied fertilization resulted in the differentiation of P, K, Ca, and Mg in leaves of the plant, but no change in N content was observed. Leaf samples collected a year earlier contained more N and P and less Ca and Mg. Leaves of sea buckthorn growing on the banks of the Odra river contained over ten times more Na, twice as much Fe, three times as much Mn as leaves of shrubs growing elsewhere. There was no difference in the amount of Mn in the leaves over the years, while those collected a year earlier contained more Fe. No presence of Mo, Pb, Cr and Cd was recorded in the leaves of sea buckthorn (Hippophae rhamnoides L.). Uptake of large amounts of Na, Ca, and Mg by sea buckthorn indicates the possibility of its growing on saline and degraded soils and the passage of time.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 Impact of form and dose of nitrogen fertilizers on the technological value of spring triticale (x Triticosecale Wittm. ex A. Camus)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Stankowski, Sławomir; Sobolewska, Magdalena; Jaroszewska, Anna; Michalska, Bożena; Department of Agronomy, 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 Meteorology and Shaping Landscape Architecture, West Pomeranian University of Technology, SzczecinThe 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.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.Pozycja Open Access Preliminary estimation the impact of effective microorganisms and fertilization on the yield, photosynthetic activity, water use efficiency of japanese knotweed (Polygonum Cuspidatum Siebold & Zucc.) and contents of selected minerals in soil(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Jaroszewska, Anna; Stankowski, Sławomir; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, SzczecinThe aim of research was preliminary assessment the influence of effective microorganisms and fertilization manure on the yield, morphological traits, photosynthetic activity, water use efficiency of Japanese knotweed (Polygonum Cuspidatum Siebold & Zucc.) and on amount of selected minerals in soil. Field experiment was conducted in 2014 and 2015 in Experimental Station in Lipnik near Stargard Szczeciński (53o12’N; 14o27’E), Poland. Experimental factors were EM – effective microorganisms (preparation) and fertilization manure. The experiment was conducted in the totally random system. The experiment consisted of four objects, in four replication: 1 – control (without EM preparation and fertilization); 2 – EM preparation; 3 – fertilization granulated manure; 4 – EM preparation and fertilization granulated manure. Effective microorganisms and manure fertilization had no significant effect on the yield, the number of plants per plot, their height, and diameter of stems of Japanese knotweed. Plants fertilized with manure and EM preparation with manure had higher concentrations of studied macronutrients (magnesium, calcium, phosphorus) and microelements. Greater intensity of assimilation and transpiration was observed in plants grown in the control plots (without EM and manure). Plant grown on objects fertilized with manure as well as EM preparation and manure- -treated better utilized water during its shortages (in 2015 year).Pozycja Open Access Water Use Efficiency and Spad Index of Fruit Trees Grown under Different Water Conditions(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2019) Jaroszewska, Anna; Podsiadło, Cezary; Stachurska, Dorota; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, PolandThe experiment was conducted in 2015 and 2016 in the Agricultural Experimental Station in Lipnik (53°20′35″N 14°58′10″E), Poland. The main goal of the study was to assess the characteristic features associated with water use efficiency and index of leaf greening of fruit trees. The experiment was designed by the randomized block method in 7 replications (one tree – one replicate) for cherry cv. ’Łutówka’, 5 replications for sweet cherry cv. ‘Vanda’, 7 replications for apple cv. ‘Rubinola’ and 4 replication for plum cv. ‘Amers’. The experimental factor was under-crown watering: 0 – control objects with no irrigation, W – irrigated objects, at the level of moisture –0.01 MPa of the water potential. Irrigated cherry and sweet cherry trees were characterized by significantly lower assimilation and transpiration intensity as well as stomatal conductance. In apple and plum cultivation, irrigation remarkably enhanced the assimilation and transpiration intensity. All tested fruit tree species grown on irrigated objects were distinguished by higher value of water use efficiency (WUE) and momentary water use efficiency (WUEI). Index of leaf greening was significantly lower for irrigated trees.
