    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kitczak, Teodor; Czyż, Henryk; Kirkiewicz, Anna; Department of Soil Science, Grassland and Environmental Chemistry West Pomeranian University of Technology, Szczecin; Department of Soil Science, Grassland and Environmental Chemistry West Pomeranian University of Technology, Szczecin; Department of Soil Science, Grassland and Environmental Chemistry West Pomeranian University of Technology, Szczecin
    The study was conducted at the Lipki Agricultural Experiment Station in Lipnik near Stargard Szczeciński on acid brown soil formed of light glacial sand on clay (5 Bw pgl : pgm), which is characterised by low content of humus on Ap level (1.57–1.59%) and clay particles (11.9–12.4%). The field experiment was set up in split-plot system in four replications, with an area of a single plot of 12 m2. The study included two factors: I – doses of phosphorus and potassium (P + K kg . ha–1): 60 + 120 and 90 + 180, II – doses of nitrogen (N kg . ha–1): 0, 40, 80 and 120. The experiment was established in 2010 by sowing Dactylis glomerata seeds of ‘Tukan’ variety (8 kg . ha–1) in spring barley harvested for grain. The study included two years of seed collection (2011 and 2012). The study determined plant density in the years of full use, number of generative shoots per plant, inflorescence length, number of spikelets and seeds per inflorescence as well as seed and straw yield. Biometric observations were conducted in 25 randomly selected inflorescences from each plot. Seed and straw yield was determined on the area of each plot during seed harvest. Dactylis glomerata of ‘Tukan’ variety was characterised by higher level of yields in the first than in the second year of seed collection. The obtained results indicate, that when establishing a plantation on light soil with companion planting in spring barley, it is advisable to use 120 kg N, 60 kg P and 120 kg K . ha–1. The increased phosphorus-potassium fertilisation (90 kg P and 180 kg . ha–1) did not change the studied morphological features of plants (number of generative shoots per plant, length of inflorescence, number of spikelets and seeds per inflorescence), while fertilising with nitrogen in doses of 40, 80 and 120 kg . ha–1 had a positive effect on increasing the above mentioned features.

    Effect of the feed additive effective microorganisms™ (EMTM) on milk and reproductive performance of polish holstein-fresian black-and-white cows
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Czerniawska-Piątkowska, Ewa; Majsakowski, Wojciech; Cioch, Barbara; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin
    The aim of study was to evaluate the influence of using EMTM probiotics in dairy cattle feeding on production and reproductive performance and birth weight of calves. The present investigation was undertaken at a large commercial farm in West Pomerania province in 2010. 211 cows were chosen to determine the effect of EMTM probiotics on studied parameters. These cows were divided into two groups: Control Group (A) and Treatment Group (B). Group B were fed during first month of the experiment 150 ml/day/animal probiotics and in next months 75 ml/day/animal. In current work we analyzed chosen reproductive parameters (age at first calving and intercalving period) and milk performance in standard lactation. It has been noticed that cows in Group B in 1st lactation characterized higher milk yield, FCM, fat and protein yield [kg] and fat content (P ≤ 0.01) compared to Group A. In addition, during comparing both groups it was found that cows in Group B in 3rd lactation received the highest milk yield, FCM, fat and protein yield [kg]. Considering protein yield the result was significant (P ≤ 0.05). On the other hand, no significant differences were found for using EMTM probiotics on reproductive parameters and calves’ birth weight [kg].

A.; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin
    The influence of selected environmental factors on shaping sandy beach habitats as a place for the growth of psammophilous and halophilous plants were the purpose of a research performed in the years 2013–2014 on Przytorska Sandbar (Natura 2000 area „Wolin and Uznam” PLH320019). The research was performed on a beach section, which was excluded from recreational use, and closely bordered with the external port basin of the Liquid Natural Gas terminal under construction, where also the abrasive influence of storm surges had been diminished. Research results indicated a dominant influence of aeolian sand material accumulation in shaping embryo dunes inhabited by pioneer species of psammophilous and halophilous plants - Elymus farctus subsp. boreoatlanticus and Honckenya peploides – species characteristic of the plant association of Honckenyo-Agropyretum juncei R.Tx. 1955, identifying the natural habitat of the initial stages of coastal white dunes (habitat code: 2110), the parts of which had been observed in the research area as a classically shaped form. The presence of Ammophila arenaria and Leymus arenarius creating initial forms of grassy vegetation association of Elymo-Ammophiletum indicated a proceeding stabilisation of embryo dunes – evolving into a foredune. A strong sea accumulation of sand material and simultaneous decrease of abrasive storm-tide influence enabled the development of an ecologically and geographically foreign species Salix daphnoides, diasporas of which were located in the area of lower beach.

    The influence of fertilisation urea phosphate on growth and yielding bush of two highbush blueberry cultivars (V. Corymbosum)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kozos, Karolina; Ochmian, Ireneusz; Department of Horticulture, West Pomeranian University of Technology, Szczecin; Department of Horticulture, West Pomeranian University of Technology, Szczecin
    An interest in highbush blueberry cultivation is growing in the world. An increase in the demand causes high prices of fruits. The success of cultivation depends on providing soil with a low pH value to the plants. The study specifies the influence of different doses (30 and 60 kg N · ha–1) of physiologically acidic urea phosphate (17.7% N, 44.6% P2O5) on the growth and yield of highbush blueberry shrubs. The studies were carried out at the Department of Horticulture, West Pomeranian University of Technology in Szczecin, at a production plantation specialized in the cultivation of highbush blueberry. The bushes were planted in soil classified as sandy silts with the content of organic matter at 4.1–4.2%. The following parameters were measured in autumn: the height of the bushes, the length of one-year growths, the number of one-year shoots growing on roots, the green index, leaf area and yield, fruit weight and firmness. The use of urea phosphate influenced the increase in the yield and size of fruits of both highbush blueberry cultivars, it did not, however, influence the increase in the height of bushes and the length of one-year shoots. It stimulated the plants to produce shoots growing on roots and the formation of larger leaves with a higher green index value as compared to unfertilized plants.

    The formation of adventitious roots is an essential step in vegetative propagation. Well-developed root system allows for easier and faster adaptation of plants to ex vitro conditions. The aim of this study was to determine the effect of exogenous auxin on Celosia argentea var.cristata (L.) Kuntze rooting under in vitro conditions and on ex vitro adaptation of those plants. MS rooting media were supplemented with IBA, IAA and NAA at subsequent concentrations 0.5, 1.0, 1.5, and 2.0 mg ・ dm−3. The results showed, that subsequent hormones had a positive effect on root development and morphology. The longest and thickest roots were formed in the presence of IBA at the concentration of 1.0 mg ・ dm−3. The highest percent of ex vitro survived plants was obtained after application of IBA and NAA (1.0 mg ・ dm−3). Plants survival ex vitro decreased (12.5–62.5%), when culture treated with IBA and NAA (1.5 and 2.0 mg ・ dm−3).

    Badaniami objęto 264 krowy rasy holsztyńsko-fryzyjskiej, o wydajności wynoszącej ponad 10 000 kg mleka, które utrzymywane były w jednym z największych gospodarstw na terenie województwa wielkopolskiego – w Sano Agrar Institut w Lubiniu. Oszacowano wpływ wieku krów w dniu pierwszego wcielenia na produkcyjność w kolejnych trzech 305-dniowych laktacjach. Analizę poszczególnych cech użytkowych wykonano na podstawie analizy wariancji, uwzględniając wpływ laktacji oraz wieku pierwszego wycielenia, jak również okresu międzywycieleniowego. Obliczono także wspołczynnik korelacji prostej pomiędzy badanymi cechami a wiekiem pierwszego wycielenia oraz długością okresu międzywycieleniowego. Najwyższą wydajność mleka, tłuszczu i białka w pierwszej i drugiej laktacji osiągały krowy, których wiek pierwszego wycielenia przypadał na okres powyżej 26 miesięcy. W laktacji trzeciej najwyższą wydajność mleka i białka stwierdzono w grupie krów wycielonych najwcześniej, tj. w wieku poniżej 23 miesięcy. Największą zawartość białka w pierwszej, drugiej i trzeciej laktacji stwierdzono w mleku krów wycielonych po raz pierwszy w wieku poniżej 23 miesięcy. Najkorzystniejszym okresem międzywycieleniowym dla badanego stada był okres powyżej 401 dni.

    Despite successful restitution in Poland, European bison still belongs to endangered species. The aim of study was to describe the morphology of the uterus of European bison and to perform morphometric analysis of the organ as well as to compare findings with available data on domestic cattle. The material consisted of female genital organs obtained from 55 females living in the Białowieża Forest. The animals were divided into two age groups. Group I consisted of 36 sexually immature females, while group II comprised 19 sexually mature animals. Significant differences were observed between the two age groups. In young female uteri, except cranial parts of horns, lay in the pelvic cavity. In older animals, most of which have already given birth, uteri were bigger, therefore only a distal half of the cervix was located in the pelvis, while the rest of the organ stretched to the abdominal cavity. Generally, the uterus of the European bison is similar to that organ in domestic cows, however some differences were specified, may be related to a different lifestyle.

    Structure and floristic diversity of the community Calamagrostietum Epigeji Juraszek 1928 within different biotopes
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Kutyna, Ignacy; Młynkowiak, Elżbieta; Malinowska, Katarzyna; Department of Ecology, Environmental Protection and Development, West Pomeranian University of Technology, Szczecin,; Department of Ecology, Environmental Protection and Development, West Pomeranian University of Technology, Szczecin,; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin
    The aim of the present paper was to determine the structure and floristic diversity of Calamagrostietum epigeji occurring within different biotopes (sand and gravel post-excavation pits, “Gilow” post-flotation waste dump, and an urban area in Szczecin). Based on previous publications, a synthetic table was compiled to present the phytosociological constancy (S) and cover coefficient (D) of species occurring in the analysed phytocoenoses. Analysis of the similarity between the communities was performed with the UPGMA method and Euclidean distances on the basis of species phytosociological constancy using the Statistica PL package. Similarity coefficients were also calculated for the distinguished phytocoenoses with the Sorensen method and the results were presented in Czekanowski’s diagram. As revealed by the UPGMA method, the greatest similarity was exhibited by communities developing within the “Storkowo I” and “Storkowo II” pits and in the “Mielenko Drawskie” pit. These phytocoenoses, which are undergoing the initial succession stage, are characterised by distinct dominance of Calamagrostis epigejos and a low number of species (from 38 to 49 taxa, on average from 10 to 15 per releve). The other group comprises communities representing later stages of succession from the “Gilow” post-flotation waste dump and the long abandoned “Krzynka” and “Szczecin- -Żydowce” pits. These phytocoenoses exhibit substantially higher floristic richness (from 61 to 114 species, on average from 15 to 20 per releve); hence, the cover coefficient of the bushgrass is considerably lower. The urban area in Szczecin is the most diverse biotope, in which, due to the more favourable soil conditions, rich phytocoenoses characterised by a mean number of 25 taxa per releve and a low cover of Calamagrostis epigejos have developed.
