This bachelor thesis focuses on the assessment of the influence of granular calcium matter applied to winter rape and its influence on exchangeable soil reaction, yield and oiliness of rape seed. The one-year field trial was based on two different localities, namely Vatín near Žďár nad Sázavou (560 m above sea level) and Žabčice (184 m above sea level). The following variants were included in the experiment: 1. Dolomite granulated, 2. Limestone granulated, 3. Dolokorn, 4. FERTI MK, 5. PhysioMax 975. The fertilizers were applied in autumn of the fourth leaf at a dose of 300 kg/ha and their influence on the exchange soil reaction, yield and oiliness of the seeds was monitored. The scaling was done in the autumn, and the effect of the applied granular calcium compounds was observed at two depths of 0 - 10 cm and 10 - 20 cm. As a result of liming, the soil reaction was higher in both localities than in the soil samples taken before liming. In a depth of 0 - 10 cm, the fertilizer FERTI MK in Žabčice showed the greatest effect and the Dolomite in a depth of 0 - 20 cm. The fertilizer PhysioMax 975 and Limestone worked the best in a depth of 0 - 10 and FERTI MK in a depth of 10 - 20 in Vatín. The yield was most affected in Žabčice by the Dolokorn fertilizer, the Limestone had increased the yield the most in Vatín. From the results of oiliness it can be said that it have been significantly higher in Žabčice than in Vatín.

Vliv řízené výživy jarního ječmene na dynamiku tvorby výnosu zrna a jeho kvality

The diploma thesis is focused on the evaluation of the influence of graded nitrogen nutrition of spring barley on the production of yield elements, grain yield and its quality by targeted application of non-root nutrition – ListerMo, which currently regulates content of nitrogen substances in grain. The small-lot field trial was based on the grounds of Agrospol Velká Bystřice. After emergence, N-fertilizers were applied at doses of N1 - 80 kg N.ha-1, N2 - 110 kg N.ha-1 and N3 - 140 kg N.ha-1. ListerMo was applied in three different phases of BBCH (25, 30, 45 - 50) during vegetation. Grain yield was comparable at N1 and N2, higher N dose reduced grain yield. Reduced grain yield reflects the effect of lower ears quantity per m2. The effect of ListerMo has been shown to reduce N-content most when applied to BBCH 30.
