The aim of this work was to evaluate the effect of storage in the enterprise as Zemke Kožlí the quality of food grains. Results of quality criteria which were in wheat moisture content , density , Zeleny test , N - substances , gluten, falling number, impurities , and malting barley moisture , overflow grains of 2.5 mm sieve , foreign seeds , cloth , damaged grains , grains fall below 2.5 mm sieve , germination , N - substances dusky peaks were processed into tables and graphs. It was demonstrated greater suitability of food grain storage in silos unlike the hall and loft storage .

The diploma thesis deals with harrowing of spelt wheat (Triticum spelta L.) by the weeding harrows and its influence on weed frequency, yield and quality parameters of wheat. In the literature review there are described general cultivation principles for the growing of spelt (Triticum spelta L.) used in current agricultural practice. There is overview of the general principles of spelt wheat cultivation in the organic farming, available varieties in the Czech Republic and brief description of agricultural technology suitable for its cultivation. We also describe the types of weeds, their brief description and the possibility of reducing their frequency in the organic farming growing system. The literature review provides also information about the technology of harrowing cereal crops as a measure to control weeds and other positive aspects of harrowing on grain crops. In the practical part, data from a field trial were collected, where the effect of harrowing on the weed frequency, the influence of harrowing on spelt wheat tillering and other parameters were statistically evaluated and compared with results in the literature. At the end of the thesis, given the results evaluated in the practical part, it was determined whether it is appropriate to use harrowing as protection of spelt wheat (Triticum spelta L.), its number, influence on weed infestation and its influence on both the quantitative and qualitative properties of spelt wheat (Triticum spelta L.).

The aim of this study was to examine the production efficiency of processed triticale and compared to unmodified triticale during 135 day feeding experiment on ponds in the system Naděj. Dosing of feed, feeding technique and condition of the market carp in experimental ponds, the quality and quantity of natural food were observed. At the end of the experiment the main production indicators were evaluated and data were statistically evaluated. Higher production efficiency of mechanical and thermally processed cereals was not proved. The highest production efficiency was observed in variant with triticale supplementary feeding without processing (FCR ? 1.4; SGR ? 0.97 %.d-1; PER ? 6.74) and in variant with thermally processed triticale (FCR ? 1.63; SGR ? 0.88 %.d-1; PER ? 5.79). The lowest effective production was reached using grinded triticale (FCR ? 1.68; SGR ? 0.86 %.d-1; PER ? 5.62). Results were affected by different levels of quantity of zooplankton in the monitored ponds.
