The investigations were couried out in 1999\u20132001 on the permanent meadow located on the gley soil. Every year of investigations the first regrowth was fertilized with NPK in the quantity: N \u2013 60 kg ha\u20131<\/sup>, P \u2013 60 kg ha\u20131<\/sup>, K \u2013 60 kg ha\u20131<\/sup>. In the experience the control combination was also applied (without mineral fertilization). The second and third regrowth was fertilized exclusively with nitrogen, applying on individual regrowths the equal doses of this component (27.6; 41.4; 55.2 kg ha\u20131<\/sup>). The nitrogen was delivered to the plants as foliar, apply respectively 20, 30 and 40% the urea solution in the volume 300 dm3<\/sup> per hectare or top-dressing as ammonium nitrate in the solid form. The results obtained in the work showed that the applied in the experience the nitrogen doses hadn\u2019t the significant influence on the agricultural and physiological efficiency. However the higher value of those coefficients was got under the influence of applying of the urea solutions in the comparison with ammonium nitrate. Utilization of the nitrogen from the fertilizer carried out average 74.8% and it was higher in the conditions of fertilization with the urea solutions than by fertilization with ammonium nitrate.<\/span><\/td>\r\n

Dynamics of botanical composition of the meadow sward as affectedby the kind of fertilization<\/span><\/p>\r\nAbstract.<\/strong> As regards meadows, the effects of manure are considered to be inferior to these of mineral fertilisers, due to the great possible loss of nutrients. The rate of ammonia lost from fermented manure which had been applied over grassland may reach up to 75%. Nonetheless, manure has a highly beneficial impact on grass production and species composition in turf, as well as it reduces harmful effects of mineral fertilisation and curbs natural propagation of meadow weeds. This research aimed to evaluate the dynamics of turf species in a meadow fertilised with manure versus mineral fertilisers. Experimental work was conducted on permanent grassland in submontane area between 1997 and 2005.<\/span><\/td>\r\n

Detailed observations dealt with the three main vegetation type swards of Glyceria maxima, Phalaris arundinacea and Agrostis stolonifera. These swards cover ca. 70% of the Park, the remaining area is mainly under herbs and Salix ssp. shrubs and trees. The use of grasslands by cattle there depends on the length of birds nesting season and on various in time spring and sometimes summer flooding. The average yield of herbage for the entire vegetation season was estimated for Glyceria maxima and Phalaris arundinacea swards to be ca. 9\u201310 t ha\u20131<\/sup> DM and for Agrostis stolonifera sward to be ca. 7 t ha\u20131<\/sup> DM.<\/span><\/td>\r\n

An attempt was taken up to evaluate the energy value of selected species that prevail in plant communities covering neglected large-area meadows situated by the Szczecin Lagoon, e.i. (Phragmitetum australis<\/i>, Phalaridetum arundinaceae<\/i>) and large-sedge reedbeds (Caricetum acutiformis<\/i>, Caricetum gracilis<\/i>, Caricetum ripariae<\/i>), molinion meadows (Molinietum coeruleae<\/i>), pastures with the common rush (Epilobio-Juncetum effusi<\/i>), and tufted hair grass (Deschampsietum caespitosae<\/i>) and common velvet grass meadows (Holcetum lanati<\/i>). The caloric value as well as crude ash content, fibre neutral and acid fractions and lignin and cellulose contents were determined. From among the examined species, the common reed proved to be particularly useful for production of bio-fuels. This species, as well as the wood small-reed, is also suitable for use as combustible material, since the caloric value of these grasses is similar to hard coal.<\/span><\/td>\r\n

It covered 18 forms of the smooth meadow-grass including 2 breeding varieties (\u2018Skrzeszowicka\u2019 = \u2018Sk 46\u2019 and \u2018Alicja\u2019) and 16 ecotypes coming from the Lower Silesian Province. Within the examined population, a large variability of traits was found, in particular with respect to flag leaf blade length, thousand seed mass and inflorescence length. The majority of the examined objects proved to be early forms, with the variability for that trait ranging from 32.3 days for DOS01 405 ecotype to 46.3 days for DOS01 229 and DOS01 468 ecotypes. Among the ecotypes, the forms occurred with higher trait values in relation to standard varieties, in particular to the turf variety \u2018Alicja\u2019. One of them, i.e. DOS01 468, obtained more favourable values with respect to mean plant height and leaf width when compared to the standard.

Ograniczenie nawo\u017cenia a sk\u0142ad chemiczny sorgacukrowego
<\/b>Reducing fertilisation and chemical composition of sweet sorghum<\/span><\/p>\r\nAbstract.<\/strong> The experiment comprised the following two experimental cultivation treatments of sweet sorghum: a\/ sowing of 180 000 seeds per 1 hectare with row seed frequency of 7 cm and b\/ sowing of 260 000 seeds per 1 hectare with row seed frequency of 6 cm. The spacing between rows was 70 cm in both treatments. The seeds were sown in the last decade of April using for this purpose a 4-row Monosem sowing machine equipped in sowing discs of 2\u20133 mm holes. The following two fertilisation combinations were applied with the above \u2013 mentioned cultivation treatments: a basic dose of: N \u2013 160 kg, P \u2013 80 kg and K \u2013 170 kg ha\u20131<\/sup> and a reduced dose of: N \u2013 120 kg, P \u2013 60 kg and K \u2013 150 kg ha\u20131<\/sup>. The control plant was maize, cv. Magister (FAO 270) which was sown at the same date and at the same row distances as the experimental sweet sorghum. Maize sown in pure stand required 90 000 seeds per hectare and the applied fertilisation was identical with that employed in the case of sorghum. Therefore, it cannot be said that changes in the fertilisation lead to distinctly worse fodder quality. From the point of view of phyto-chemistry, it is possible to apply in the cultivation of sweet sorghum the following doses of fertilisers: N \u2013 120 kg, P \u2013 60 kg and K \u2013 150 kg ha\u20131<\/sup>. Economic calculation should play a decisive role in the selection of the method of cultivation and fertilisation.<\/span><\/td>\r\n

<\/b>Assessement of productivity of meadow sward after sowing with annual mixture (research note)<\/span><\/p>\r\nAbstract.<\/strong> The Spring 2006 year at Paw\u0142owice Experimental station field experiment was conducted using undersown crop on three treatments A0<\/sub> \u2013 control, A1<\/sub> \u2013 with grass mixture Topmix 1 and A2<\/sub> \u2013 with grass mixture in four fertilizer variant: B0<\/sub> \u2013 0, B1<\/sub> \u2013 PK, B2<\/sub> \u2013 90 kg N + PK, B3<\/sub> \u2013 180 kg N + PK per hectare. Two-cut use was employed. The aim of the experiment was the assessnent of the effect of type of grass annual mixtures and varying mineral fertilization on sward productivity in climatic-soil condition of Lower Silesia region. Results show that profitable changes in botanical composition and increasing yielding of sward was observed under using of Topmix 1 and using of mineral fertilization positively affected botanical composition. The highest number of undersown grass species was noticed on treatments with rate of 90 kg ha\u20131<\/sup>NPK fertilization.<\/span><\/td>\r\n
