<abstract xmlns="http://www.w3.org/1999/xhtml">This study is focused on principles of rain gardens in landscape architecture and their application in Slovak conditions. Rain gardens can be seen as a part of sustainable design and application of ecological principles in changing natural conditions. The simplicity of a rain garden represents combination of rainwater management and flower planting, which is a strong landscaping element because of the connection between ecology and aesthetics. Plants used in rain gardens help to keep water by the root system and, after that, to transpire it. Another importance of this kind of arrangement is its simplicity and positive impact on creation of a new bio-retentive ecosystem, which is able to safely collect, absorb, filtrate and carry off rain water from paved areas. Many foreign countries have understood their importance and have already implemented them in new projects of public and private spaces. This paper also describes a theoretical planting proposal of a rain garden in a housing estate in the city of Nitra to demonstrate a real application of this technique in Slovak conditions.</abstract>

The aim of the work was to study the influence of lighting on the young plants quality in selected 11 vegetables species. The experiment was carried out during the winter time in a heated greenhouse of the Botanical Gardens of SUA in Nitra. For the lighting there were used linear fluorescent lamps FLUORA T8 - L 36W / 77 - G13 during the whole period of cultivation. According to our results, the lighting had a positive impact on the quality of harvested plants. The higher contents of vitamin C, chlorophyll <italic>a</italic> and chlorophyll <italic>b</italic> were estimated in comparison with the control variant without lighting.</abstract>

These stilbenes have also important healthy effects for humans. Resveratrol and viniferins are known as phytoalexins since 1977. Biomass of grape canes in annual pruning is a very valuable source of stilbenes, e.g. <italic>trans-</italic>resveratrol, and <italic>trans-</italic>ε-viniferin in dry grape canes. The main goal of this article was to compare the distribution of resveratrol and viniferins in the grape cane varieties of Laurot, Hibernal, Malverina and Chardonnay. The highest content of <italic>trans-</italic>resveratrol was found in Hibernal (6,111 mg kg−1); for <italic>trans-</italic>ε-viniferin and r2-vinifein, the highest levels were found in Malverina (2,211 and 654 mg kg−1). These compounds can be obtained from this waste product (grape cane), by easy extraction process in winemaking or food-processing industry.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Separate collection of biodegradable municipal waste (BMW) is the main precondition to decrease the environmental pollution by landfill gas as well as to enrich soil by the humus substances from municipal compost. However, the obligation to ensure the separation and treatment of the BMW increases the municipalities' costs for waste management. Rural areas differ from the urban ones not only by typical lifestyle, settlement character, but also by total BMW production. The urban areas do have easier access to public finances, therefore, most of them already dispose sufficient infrastructure for BMW gathering and treatment. The aim of our research was to analyze the spatial production and disposal of the biodegradable municipal waste and propose, in regard to legislation, efficient BMW treatment for rural areas of the Nitra region. The analysis revealed that only 23% of the examined municipalities dispose through composting. However, 92% of them have the estimated annual BMW production from public green areas not exceeding 100t. Organic waste processing could be managed by municipalities through “small composting” which does not require the approval by the state body in waste management.</abstract>

Spatial Analysis of the Biodegradable Municipal Waste Production and Disposal

<abstract xmlns="http://www.w3.org/1999/xhtml">The paper proposes a methodology for calculating the weights of factors determining the choice of location of municipal waste incineration plant (MWIP). Objective and accurate determination of the weights offers the optimal choice of location. To achieve the planned purpose, the method of the analytical hierarchical process was applied. The study included seven potential locations for the municipal waste incineration plant, located within the area of the city of Krakow. The objective of the analysis, which is the subject of this publication, is determination of weights of factors decisive for the choice of MWIP location. These weights were calculated using the method of the analytical hierarchical process. The choice of the method is dictated by the fact that in the studied case we deal with multivariate analysis, and its components are described both in quantitative and qualitative ways.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Soil water content is very important for agricultural practice. Direct measurements of the soil moisture are being replaced by mathematical simulations and models step by step. One of the most used models for the simulation of the soil moisture is HYDRUS 1D model. This paper deals with HYDRUS 1D validity check in the Nitra River Catchment. Three different localities in the Nitra River Catchment (Malanta, Kolíňany and Dolné Naštice) were chosen for model validity check. Both, measurements and modelling of soil moisture, were made for these localities in three years (8/2011 - 8/2014). The evaluation of model validity was performed by calculation of the correlation coefficient and count of comparisons with variance of 15%. The correlation coefficients of measured and simulated data were between 0.67 and 0.95. Data comparisons with variance of 15% among measured and simulated data were between 79 to 100%. Based on these results we can declare that HYDRUS 1D model is valid for the conditions of Slovak catchments.</abstract>
