Pozycja Open Access Ocena odrastania muraw trawnikowych z udziałem śmiałka darniowego(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Jankowski, Kazimierz; Jankowska, Jolanta; Sosnowski, Jacek; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachThe aim of this work was to evaluate the usefulness of tufted hairgrass to establish turf lawns used extensively as a result of the impact of it’s on the degree of lawns regrowth. Field experiments were founded in April 2003. In one experiment were sown the seeds of five grass species in pure sowing on the plot with an area of 1 m2. It was tufted hairgrass, clump red fescue, rhizomes red fescue, tall fescue, kentucky – bluegrass. In the second experiment were sown mixtures of this grass species with tufted hairgrass. Seeds for these experiments came from IHAR in Radzików. In the first experiment, research factors were 5 species of grasses and 3 date of observation and in the second – 5 kind of mixtures and 3 date of observation. As a date for observation for the spring was adopted mid-May, for the summer mid-July, for the autumn mid-October. The study was conducted in the years 2004–2005 by making systematic observations once a season (spring, summer, autumn). Each year of the study the lawns regrowth were evaluated. This evaluation was made according to the COBORU methodology. Valuation used 9o scale, where 9 meant the best value of this feature. Regrowth of tufted hairgrass turf was slower than kentucky bluegrass or red fescue, and so this species which are commonly used in lawn mixtures with varying suitability. From the five lawn mixtures established on the tufted hairgrass base, a mixture consisting of 50% of the tufted hairgrass and red fescue the slowest regrowth was characterized. The slow regrowth rate of tufted hairgrass both in monoculture and in mixtures create the possibilities to use this grass species in greater extent to the establish of lawns especially those that will not require too frequent mowing.Pozycja Open Access Wpływ użyźniacza glebowego na efektywność nawożenia azotem mieszanek Festulolium braunii z koniczyną łąkową i lucerną mieszańcową(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Sosnowski, Jacek; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachIn order to determine the effects of soil fertilizer and species composition and quantitative of Festulolium braunii mixtures with red clover and alfalfa on the efficiency of nitrogen fertilization, on the experimental object of Grassland Department and Green Areas Creation the experiment with these species was established. Surface plot was 6 m2 . The period of full, three – cuts using of this objects was in 2008–2010. The first experimental factor were three grass – legume mixtures with different grass species composition and quantity. The second factor was the soil’s fertilizer, which was used for a once watering plants in the phase of grasses shooting in the first regrowth as a solution at a dose of 0,9 l · ha–1 diluted in 350 l of water. In the order to determine the efficiency of nitrogen utilization, the following levels of this factor were introduced: N0 – no nitrogen and N1 – nitrogen in dose 60 kg N · ha–1rocznie (34% ammonium nitrate). In addition to all plots potassium fertilization at 40 kg K2O · ha–1 and phosphorus in a dose of 80 kg P2O5 · ha–1 were used. During the full utilization of the objects, the detailed study included: plant dry matter yield (t · ha–1) and total protein content (%). Based on these characteristics, it was calculated the nitrogen taken with the yield and the following indicators: Er – agricultural efficiency (agronomic), Ef – the physiological efficiency and W – the nitrogen utilization. The study showed that application of soil’s fertilizer to supply the analyzed mixtures did not resulted the increase of nitrogen utilization from fertilizer caused only an increase of its uptaking which resulted in a higher value agronomic and physiological efficiency of crops. While the nitrogen utilization supplied with mineral fertilizer was the highest on the objects with two–components mixtures.Pozycja Open Access Wpływ zróżnicowanej dawki odpadu popieczarkowego na cechy jakościowe muraw trawnikowych(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Jankowski, Kazimierz; Czeluściński, Wiesław; Jankowska, Jolanta; Sosnowski, Jacek; Wiśniewska-Kadżajan, Beata; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Pracownia Agrometeorologii i Podstaw Melioracji, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w Siedlcach; Katedra Łąkarstwa i Kształtowania Terenów Zieleni, Uniwersytet Przyrodniczo-Humanistyczny w SiedlcachThe field experiment was established in 2004 on the object of the University of Natural Sciences and Humanities in Siedlce. In the conducted experiment, the following factor was applied: mushroom’s substrate doses (0, 2, 4, 6 kg · m–2). In the study a commercially available grass mixture of Super gazon was used. On the all experimental objects mineral fertilization in the form of Pokon fertilizer was used. In each year of the study many characteristics were evaluated such as the general aspect, compactness, color and regrowth. Additionally, in the autumn of each study year the root biomass produced by the turf was determined. The value of all studied features of turf lawns has improved with increasing the doses of mushroom’s refuse and this refuses effected the turf compactness as the most favorable.Regardless of the mushroom’s refuse dose more favorable values of the studied features the turf lawns reached in the first year of the study, than in the second. It may indicate about weakening effect of the impact of used mushroom’s refuse in subsequent study years.
