Pozycja Open Access The assessment of water sanitary quality and the presence of drug-resistant Escherichia coli strains in waters used for recreation in lesser Poland(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Chmiel, Maria J.; Wójtowicz, Paulina; Łojas, Ewelina; Department of Microbiology, University of Agriculture, Kraków; Department of Microbiology, University of Agriculture, Kraków; Department of Microbiology, University of Agriculture, KrakówThe presence of multi-drug resistant bacteria is no longer only a clinical problem because increasingly, during the microbiological water and soil analysis, the antibiotic resistant bacteria are isolated, which can be a significant health hazard. The aim of this study was the assessment of water sanitary quality and the occurrence of drug resistant strains of Escherichia coli in 10 sampling points located on selected water reservoirs used for recreation on the Dunajec river and reservoirs in Krakow area and Kryspinow. Collected water samples were examined by the membrane filtration technique to assess the number of E. coli. Drug resistance was tested using the disc diffusion method as well as the ESBL assay according to KORLD and EUCAST standards. Based on the results, it was found that in two sampling points located on the Biały Dunajec river the population of E. coli exceeded standards intended for bathing. Resistant strains were isolated mainly in one bathing place - Kryspinow – Na Piaskach, but they were also present in the waters of the Dunajec river. Most often isolates were resistant only to one of the tested antibiotics, the multidrug resistant E. coli were no isolated. The tested strains were mainly resistant to ticarcillin, sulfamethoxazole/trimethoprim and tetracycline. All the tested strains were ESBL negative.Pozycja Open Access The impact of sewage sludge and biomass ash fertilization on the yield, including biometric features and phyisiological parameters of plants of two jerusalem artichoke (Helianthus tuberosus L.) cultivars(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Puchalski, Czesław; Zapałowska, Anita; Hury, Grzegorz; Department of Bioenergetics and Food Analysis, University of Rzeszów; Department of Bioenergetics and Food Analysis, University of Rzeszów; Department of Agronomy, West Pomeranian University of Technology, SzczecinJerusalem artichoke is one of such plants that can be put to energy use. The objective of the research study was to assess the impact of fertilization with sewage sludge and conifer sourced ash biomass on yields as well as biometric and physiological parameters of two cultivars (Albik and Gigant) of Jerusalem artichoke (Helianthus tuberosus L.). The two-year study was carried out in fields located in Ujkowice near Przemyśl. The trials covered 3 factors, as follows: 4 levels of fertilization with biomass – ash from conifers, 2 levels of fertilization with sewage sludge, 2 cultivars of Jerusalem artichoke (Helianthus tuberosus L.) – Gigant and Albik. In the first year after the application of sewage sludge in an amount of 30.3 t ∙ ha–1, the yield was lower by about 0.8 t and in the second, the reaction to fertilization using sludge was positive. Differences in yield under varied levels of fertilization with sewage sludge depended on the length of shoots as well as the LAI and SPAD indicators. Biomass ash fertilization resulted in systematic increase in yields of the vegetative (aerial) parts in 2013. In the subsequent year, differences were insignificant. Yield increase in Jerusalem artichoke fertilized with biomass ash was associated with increased lengths of shoots, increasing values of the LAI and SPAD. There was no significant interaction between the organic and mineral fertilization. Amongst the two tested, Albik cv. was characterized by higher yields. The Polish Albik cv. was characterized by higher shoot lengths, smaller shoot diameters, higher LAI index, and a much higher SPAD (cultivar related features) value, while the Fv/Fm index for both cultivars was similar.Pozycja Open Access The influence of farming systems on the technological quality of grain and flour cultivars of winter wheat(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, SzczecinThe 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.Pozycja Open Access Rating long-term use of simplifications in tillage and previous crop on biometric features, physiological and yield of winter wheat cultivar ‘Kobra Plus’(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Schiller, Marta; Stankowski, Sławomir; Podsiadło, Cezary; Pużyński, Stanisław; 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 Agronomy, West Pomeranian University of Technology, Szczecin; Department of Meteorology and Green Areas Management, West Pomeranian University of Technology, SzczecinThe study was conducted in the years 2006–2008, in a static experiment founded in 1993 in the Agricultural Experimental Station Lipnik (near Stargard Szczeciński). The station is located in the central part of the Szczecin Lowland (ϕ53021`N, 14058`E, Hs 30 m.a.s.l.). Field tests were carried out using winter wheat grown in four-field crop rotation (sugar beet – winter wheat – faba beans – winter wheat + white mustard intercrop). The effect of simplified tillage involving the elimination of plowing for the plowless tillage and direct sowing was examined, as compared to conventional tillage under crops grown in rotation. Studied factor consisted of the farming systems used for winter wheat after different forecrops (faba beans, sugar beet). The tillage systems significantly shaped the length of the stalk and leaf assimilation index (LAI). Winter wheat grown in the field after faba bean had significantly higher values of total number of steam and, with ears, the length of stalk and spike, as well as the ratio of leaf greenness (SPAD). In our study, there was no the effect of experimental factors and their interaction on grain yield of winter wheat. Regardless of tested experimental factors, winter wheat yielded at the level of 5 t ∙ ha–1. A slight tendency to higher yields was recorded for the traditional plowing system.
