The barley growing in terms of selected agricultural company
ČÍTKOVÁ, Šárka
The aim of the bachelor thesis was to quantify the effect of the form of nitrogen fertilization on the yield and quality of barley. For this purpose, a pilot experiment was established on a family farm near Tábor. The experiment was based into two variants: variant I using a solid form of nitrogen fertilizer - ammonium nitrate and variant II using a liquid form of nitrogen fertilizer - urea. The nitrogen dose for both variants was 100 kg.ha-1 No. b. The monitored indicators were the number of ears per m2, the number of grains in the ear, 1,000 K weight, the proportion of front grain, the content of crude protein and germination. In the number of ears per m2, the number of grains, the proportion of front grain, the crude proteinand germination, the variant using ammonium nitrate reached higher values. The 1,000 K weight value was the same for both variants.

Zhodnocení rozdílů v aktuálním zaplevelení vybraných polních plodin
Miškařík, Petr
The aim of the study was to determine the actual weed infestation of crops in two ag-ricultural-production companies with different conditions for growing plants. Evalution was carried out counting methods. The results of the weed infestation evaluation were processed with the DCA analysis. The canonical corespondence analysis showed that, were found: Capsella bursa-pastoris in the crop Trifolium pretense a Zea mays, in the crop Triticum aestivum, Capsella bursa-pastoris in the crop Hordeum vulgare a Galium aparine in the crop Secale cereale

Produkce biomasy ječmene setého v závislosti na parametrech kořenového systému
Foltýn, Martin
The thesis deals with production of biomass of spring barley (Hordeum vulgare, L.) depending on the parameters of a root system. The theoretical part is focused on the methods of assessment of root system of plants, the influence of environment and genotype on the qualities of a root system of plants and on the relation between the parameters of a root system and the yield of field crops. Another part of the thesis is a statistical assessment of the results of a field experiment with spring barley, which was realized in the locality Hořejší Kunčice in 2014 and in the localities Hrubčice and Želešice in 2012 and 2013. By means of the method of measuring electrical capacity, the size of the root system of four varieties of spring barley and their hybrids was assessed in three development stages: BBCH 36, BBCH 55 and BBCH 71. The yield of grain and the yield of biomass were assessed in the stage BBCH 89. An important influence of the size of the root system on the yield of grain in stage BBCH 55 (r = 0,643*) was discovered in 2013 in Hrubčice. In Želešice, 2013, an important influence of the size of the root system on the yield of grain was found in all the examined development stages, BBCH 36 (r = 0,650*), BBCH 55 (0,824*) and in the stage BBCH 71 the influence was highly important (r = 0,839**).

The cereals growing in ecological farming system
VESELÝ, Tomáš
In this work were compared differences between organic, transitional and conventional farming systems. Grain yields were compared, the amount of agricultural engineering and economics in a selected company Farma Otročín Ltd. In the years 2007-2014.
