The influence of foregoing crop on oats yield and quality
POLÁČKOVÁ, Jitka
Nowadays trend in Europe is returning to harvesting of traditional feeding crops. One of these crops is oat which has been universally used since time immemorial. Even today oats are processing and using in food industry and as a feed for farm animals. Further using of oats is in cosmetics and pharmaceutical industry. Oats contain high amount of proteins and fats, beta-glukan and mineral elements. Oats include vitamins B and E, lecitin, niacin and antioxidants. Research was executing on fields of University of South Bohemia in České Budějovice during one year. An impact on crop yield and quality of oats was observed in dissertation. There were used three crops corn, rape and cereal (spring wheat) in research. After these crops were sown ten varieties of oats, four naked and six husked varieties. At these varieties were observed an impact on crop yield and quality of oats. Evaluated characters were monitored during the vegetation, pre-harvest and post-harvest. There were observed germination and methane, height of vegetation, the degree of lodging oats, the number of lat m2, weeds, diseases and pests, after harvest was determine harvested grain yield, moisture and density, number of grains per panicle, thousand grain weight and grain on a network share during the vegetation. From the measured values follows that the best crop in year 2012 was corn and the best results were achieved by variety Abel, Avenuda, Atego, Pogon, Salo.

The quality of food wheat in South Bohemia
MACHOVCOVÁ, Dana
The quality of food wheat is annually evaluated with all deliveries of agricultural primary production in the chosen farming enterprise. During the years 2008 - 2012 particular characteristics with files of 42 - 222 samples were determined, except for the year of 2009 when only one supply was technologically incorporated to food wheat. Countrywide observation of the quality of food wheat is executed in Agricultural research institute Kroměříž, Ltd and in Agrotest fyto, Ltd. It is co-financed by Ministry of Agriculture within a functional task which follows the project of Ministry of Agriculture number QG50041 Factors of quality and safety with food grains (2005-2010). Harvest samples, obtained from producers in time span 2008-2012, were represented by files of 500-1035 samples. Characteristics which influence the quality of the grains as well as criteria and methods of the evaluation of food wheat were described. Their applications in Agrotest fyto, Ltd and under operating conditions in ZZN Pelhřimov a.s. were given. Average values of observed parameters were calculated from the results of each testing in the laboratory of the detached post Záhoří and consequently compared with countrywide norm and the norm of South Bohemia. The quality of food wheat grains in years 2008-2012 showed a large-scale variability in particular parameters both at countrywide level and in South Bohemia as well as in chosen farming enterprise. Final quality was considerably influenced by course of weather annually.

The comparison of winter and spring wheat quality
UHLÍKOVÁ, Jindřiška
The theme of this Bachelor's thesis is to compare the grain quality of winter and spring wheat varieties. There were a total of 16 selected varieties, 12 of winter- and 4 of spring. The experiment was conducted on the grounds of the South Bohemian University in Ceske Budejovice. The botanic characterization of wheat, the chemist of wheat grain and the quality parameters used for examination are mentioned in the introductury part . The first part of the experiment was focused on the control during the growth, the second part documents the analysis of examined samples (mass per hectolitre, N-substances, gluten, Zeleny test, falling number).

The quality of wheat for food and feeding
MACHOVCOVÁ, Dana
The quality of wheat meant both for food industry and for feeding is evaluated with all deliveries from co-operative farms, concerns and private farmers every year. Factors which can influence quality of grain, criteria for evaluation of the wheat grain quality, their practical use in working conditions of the concern ZZN Pelhřimov (former Grana, a.s.) detached post Záhoří and results of accomplished tests compared with statewide average were described. Average values of the wheat in 2007 - 2010 demonstrated variability in each characteristics both in the chosen concern and in statewide average. Weather conditions influenced the quality of most parameters. Considerable difference in the quality of grain could be found with particular distributors. The proper agricultural engineering and good seed corn are essential preconditions of first-rate production.
