The aim of thesis was The use of ornamental value of vegetable species. The literary section describes the history and current developments of use of vegetables, next are described compositional properties and characteristics of selected vegetable species. For the assessment of vegetables in the practical part was chosen Flower Garden in Kroměříž as a model object. There were realized two ornamental vegetable beds on which were the due to methodology of ornamental value evaluated each of vegetable species and cultivars of vegetables. All of data were processed in program Statistica 12 and were made conclusions for practice. The result is an inventory table of compositional properties of vegetables and chart of the overall evaluation of selected types of vegetables, including an economic evaluation of the cost of foundation of 1 m2 of plantings.

In the vintages 2007 (autumn culture) and 2008 (spring and autumn culture), there were grown broccoli varieties ''Belstar F1'' , ''Lucky F1'' and Japanese type of radish, variety ''Jarola F1'', on the certified organic land in Prague - Troja , and simultaneously on the neighbouring conventional plot to evaluate their quality. The experiment was set up with two densities of vegetation , broccoli: 0.6 x 0.5 m, 0.5 x 0.5 m and radish: 0.20 x 0.35 m, 0.30 x 0.35 m. The market production was evaluated for subsequent nutritional values : dry matter , fiber , total carbohydrates, vitamin C, total carotenoids and chlorophyll, minerals (potassium, sodium, calcium, magnesium), total antioxidant capacity ,further also nitrates, electrochemical value (electrical conductivity, pH, redox potential) is expressed as a P value and a sensorial value using the descriptors recommended in the publication (Kopec, Horčín, 1997) . The evaluation of organic and conventional production of broccoli and radish showed that the ecological system of cultivation inconclusively increased the content of carotenoids and minerals in broccoli and vitamin C, carotenoids and sodium in radish. In other nutritional characters, the difference was negligible. Statistically significant effect of the most characters was evaluated also for the season of cultivation and occasionally the density of vegetation. Sensory evaluation of broccoli was in the spring term in favor of conventional production and in the autumn of 2008 in favor of organic production . The radish grown in autumn 2007 did not show any significant difference, the autumn term of growing in 2008 was in favor of organic production.
