Stanovení optimálních parametrů pro ošetření kmínu plazmovým výbojem
 ROUHA, Pavel
The focus of this bachelor thesis is on the use of plasma discharges in agriculture, more specifically in the treating of seeds of caraway using low-pressure plasma equipment Plasonic AR-550-M. The theoretical section is made up of two parts. The first one is a literary research on the caraway, its history and present, the history of its growing in the Czech Republic and the botanical and biological characteristics of this plant. The second part is devoted to plasma, its principles, types of plasma discharges and its use. The practical section contains a description of plasma equipment Plasonic AR-550-M and a brief instruction manual. Furthermore, there is a methodology of realization of measurements and its results that explain the effect of the plasma discharge on caraway seeds.

Varietal quality of malting barley
 KADLECOVÁ, Helena
By purchasing malting barley the quality is evaluated according to standards, techniques, laboratory methods and qualitative indicators, which are set by norm. Evaluation of quality of barleycorn as a material for producing malt is used for setting the price, observing changes of the quality during storing etc. There were evaluated qualitative indicators of 13 sorts of malting barley, which were bought by company ZZN Pelhřimov between 2010-2014 from farmers, agricaltural cooperatives and companies and also self-employed farmers from the region Vysočina. These sorts were represented by different number of samples in connection with bought-up amount and number of supplies of each sort. Weighted averages were counted from results. Average figures of results of analysis were compared with the national average. Research institute of brewer´s and orchardist a.s. in Brno deals with monitoring of quality of malting barley in the Czech Republic and it evaluates annually ca. 500 harvest samples which were received by producers from all regions in the Czech Republic. The quality of malting barley showed a big variability in all parameters across all types and also in particular years. Malting quality is influenced by many factors especially by course of weather in each particular year. Limiting parameter of quality by purchasing malting barley was N- substances content in barleycorn. Germination capacity seems to be the most stable from all parameters. Lower figures of germination capacity were found only by winter types in connection with longer period of ripening after harvest.
