<\/strong><\/span>Yielding and energy value in selected species of tall grasses<\/span><\/p>\r\nAbstract.<\/strong> The experiment was conducted in the year 2007\u20132010 in the Agricultural Experiment Station in Ba\u0142dy owned by the University of Warmia and Mazury (NE Poland). The experiment was established in a randomized complete block design, in 4 replications on grey-brown podsolic soil of quality class IVa. Plough layer described as medium abundance of available potassium and magnesium and low availability of phosphorus with neutral soil reactivity (pHKCl<\/sub> \u2013 7.2). The first examined factor was three species of tall grass, seeded in rows as a pure species on 30th of August 2007: Dactylis glomerata<\/em> L. variety Bepro, Arrhenatherum elatius<\/em> (L.) P.B. variety Median and Bromus inermis Leyss. variety Lufa. The second factor was the level of nitrogen fertilization. Since 2008 of fertilisers ware used: N0<\/sub> P35<\/sub> K100<\/sub> kg\u00a0ha\u20131<\/sup>; N60<\/sub> P35<\/sub> K100<\/sub> kg\u00a0ha\u20131<\/sup>; N120<\/sub> P35<\/sub> K100<\/sub> kg\u00a0ha\u20131<\/sup>; N180<\/sub> P35<\/sub> K100<\/sub> kg\u00a0ha\u20131<\/sup>. In the years 2008\u20132009 one production harvest was collected (respectively: 21st and 20th of August), and in 2010 two yields were harvested (on 21st July and 4th October). The yield of dry matter of grass, heat of combustion, calorific value, ash, carbon and sulfur content had been determined. The purpose of the experiment was to determine the yield and energy value of tall grass biomass according to variant doses of nitrogen fertilization.<\/span><\/span><\/td>\r\n

The one-factorial experiment was established in two repetitions. The following parameters were analysed: density and height of generative shoots, structure of inflorescences and spikelets as well as efficiency of seed set. It was concluded that cultivars of Poa pratensis<\/em> differ significantly in morphological-biological features determining biological seed yield. Law cultivars develop significantly more generative shoots per 1 m2<\/sup> and less spikelets per inflorescence than fodder ones. \u00a0<\/span> <\/span><\/span><\/td>\r\n

It was concluded that differentiation of Poa pratensis<\/em> cultivars in harvested seed yield is higher along with the successive years of their utilization. The cultivars of Poa pratensis<\/em> are characterized by specificity of seed yield in terms of quantity and distribution in the years of growing for seeds. The fodder cultivars develop higher seed yield in first and second while the lawn cultivars \u2013 in the third year of utilization.\u00a0<\/span><\/td>\r\n

<\/strong><\/span>Flowering of selected plant species of xerothermic grasslands in the \u201eWinnica\u201d Flora Reserve<\/span><\/p>\r\nAbstract.<\/strong> The aim of the study was to determine the date of initiation of flowering and the duration of flowering for focal species and to compare our data with that presented in the botanical key \u201ePolish Plants\u201d (Szafer et al., 1967). The studies were conducted in the \u201eWinnica\u201d Flora Reserve which is situated in the Landscape Park \u201eWarta and Widawka\u201d (\u0141\u00f3d\u017a voivodeship). The weather conditions significantly affected the course of the flowering phase. For most of studied species, the drought delayed the moment of occurrence of flowering and caused the shortening of duration of this phase. Both an earlier start of the flowering phase (Melampyrum arvense<\/em>, Centaurea stoebe<\/em>, Aster amellus<\/em>), and delay in start (Euphorbia cyparissias<\/em>, Galium verum<\/em>, Stachys recta<\/em>, Anthemis tinctoria<\/em>, Medicago falcata<\/em>, Agrimonia eupatoria<\/em>, Brachypodium pinnatum<\/em>) were observed in comparison with the dates published by Szafer et al.

The objects of the research were plant communities in part of the Garden where restoration of extensive sheep grazing is planned. Natural values (number of species, total and in patch, Shannon-Wiener\u2019s floristic diversity index), and production value (yielding, fodder value) were evaluated. It was found that the current state of grass communities does not meet the required parameters of sward and it is necessary to introduce color-flowering herbaceous species, previously existing in this area.<\/span><\/td>\r\n

<\/strong><\/span>The effects of changes in the use of permanent grassland in the Carpathian areas<\/span><\/p>\r\nAbstract.<\/strong> The study aimed to identify and parameterize environmental effects that occur as a result of changes in permanent grassland in mountain areas. In the years 1980\u20131999, the area of grassland was only a little variable and fluctuated within 10% in the upper Raba River basin and 20% in the upper Dunajec River basin, as regard to their total areas. This, however, was mainly due to the extensification of agricultural production and the self-sodding of arable fields. The highest water pollution was recorded in the vicinity of dense built-up areas. In contrast, where the share of grassland area was significant, pollution of surface water was reduced. At present, grassland in the mountains fulfill primarily ecological, aesthetic-recreational and health functions, and then economic (agricultural or non-agricultural) role.<\/span><\/td>\r\n

<\/strong><\/span>Economically unexploited permanent grassland in Che\u0142m County as a potential source of biomass production for energy generation<\/span><\/p>\r\nAbstract. <\/span><\/strong>Studies were conducted in 2012\u20132016 in Che\u0142m County to determine the energy potential of biomass from economically unexploited permanent grassland. Its energetic value was estimated from data published by the Central Statistical Office of Poland (GUS) and the average calorific values of biomass from the plant communities. It was concluded that this lies in the range of 16.82 \u2013 16.94 MJ kg\u20131<\/sup> DM and is comparable to the calorific value of exotic grass varieties used for energy purposes, and as such could constitute a significant proportion of Che\u0142m County\u2019s energy balance. Dedicating economically unexploited biomass to energy purposes may also avoid the natural succession of grass communities and avoid them being degraded by discontinued use.<\/span>

The soils were characterised by diverse soil moisture and floristic composition.

Low content of macro- and micronutrients in the soil was reflected by the chemical composition of plant samples.

<\/strong><\/span>Evaluation of germination of seeds of lawn grass mixtures coated with iron sulphate aiming moss control<\/span><\/p>\r\nAbstract. <\/span><\/strong>Iron salts are often used in pesticides to moss control in lawns, causing them to quickly blacken and die. In order to check the influence iron sulphate used in the lawn grass mixtures for coating the kernels on their germination a laboratory and greenhouse pot experiments were carried out. Seeds germination was tested on Petri dishes with tissue paper and in conditions of seeds sowing into the soil. The concentration of iron sulphate of the mixture R determined in 1 gram in the amount of 1,5 mg of Fe, did not inhibit the germination and development of seedlings. In the mixture G, the concentration of 31,92 mg of Fe used for the coating of 1 gram of kernels, proved too high, preventing germination on Petri dishes. Sowing the seeds of this mixture to the soil, significantly reduced the effects of the adverse impact of high iron salt on their germination. However, the level of germination of kernels after 20 days was significantly lower, compared to the R mixture, ranging from 73 to 78%.<\/span> <\/span><\/span><\/td>\r\n
