The aim of this study was to determine the effect of cadmium (10, 20, 30 and 40 mg Cd/kg of soil) contamination in soil with the application of different substances (compost, brown coal, lime and bentonite) on the intake of nitrogen by some plants. The correlations between the nitrogen content in the plants and the cadmium concentration in the soil, as well as the plant yield and the content of micro- and macroelements in the plants were determined. Plant species and cadmium dose determined the effects of soil contamination with cadmium on the content of nitrogen. Large doses of cadmium caused an increase in nitrogen content in the Avena sativa...

In this study experiments primarily aimed at the needs of specification of an adequate soil reserve of labile sulphur were extended by investigations of the impact on interactions in nutrient uptake by a test barley plant. Vegetation (18-day) experiments under controlled conditions of cultivation were conducted on a diverse set of 48 soils from agricultural lands. Before barley sowing the experimental set of soils was divided into two variants: A - control (with NH4Cl application) and B - response variant [with (NH4)2SO4 application], and a uniform dose of 26 mg N/kg soil was used. After the experiment terminated,...

A vegetation pot experiment was established to explore the effect of two doses of nitrogen (0.6 and 0.9 gN in the form of ammonium sulphate) and two doses of sulphur (20.6 and 30.6 mg/kg of soil) on the yields and quality of spinach and pepper in comparison with a natural level (7.85 mg/kg). The results of the experiments confirmed that the application of sulphur by means of (NH4)2SO4 in combination with nitrogen had a positive effect on yields and also on the quality of the vegetables. In the sulphur-free variants of spinach the effect was statistically significant and also when the levels of S in the soil were higher....
Effect of topdressing with nitrogen on the yield and quality of winter wheat grain

Small-plot field experiments were established in the first decade of October at the Plant Breeding Station of Sládkovičovo-Nový dvor with winter wheat (Triticum aestivum L.), variety Astella. There was investigated an effect of topdressing with nitrogen on the yield of winter wheat grain and its quality characteristics in the experiment. Nitrogenous fertilizers were applied at the growth phase of the 6th leaf (Zadoks = 29). Soil of the experimental stand was analysed for inorganic nitrogen content (Nan) down to the depth of 0.6 m of soil profile. Productive nitrogen fertilizing rate was computed to ensure Nan...
Effect of legume proportion and physiological age on forage quality and the suitability of Agrostis capillaris L. and Festuca rubra L. for silage making

The chemical and physical properties of herbage from low-input grassland usually differ from plant material of intensively managed swards. The experiment in split-plot design with four replicates was carried out to examine, whether legume proportions and the physiological age of herbage are relevant to fermentability of herbage. Lotus corniculatus did not increase nitrate concentrations sufficiently in Festuca rubra and most Agrostis capillaris swards to be able to avoid clostridial fermentation. However, Lotus corniculatus reduced the WSC/BC ratio of the grasses grown in mixture and that of the complete herbage...
Effect of different mulching and cutting regimes on the vegetation of upland meadow

The effect of different cutting and mulching regimes on the structure of the sward and plant species diversity of semi-natural meadow (Arrhenatherion alliance) was investigated in manipulative experiment over five years. Mulching once a year in September (MS) and plots without management (U) developed in the same way and resulted in increase of Veronica chamaedrys and Galium album and disappearance of light sensitive Trifolium repens. T. repens increased in two cut, two cut without removal of the biomass and in three times mulched treatments. The lowest species diversity was recorded under MS and U treatments...
