Effect of different width of rows on biomass yield and dry matter content at growing sorghum
KUBEŠ, Pavel
The aim of this thesis was to determine the effect of row spacing on sorghum yields and dry matter. The trial was established on 29 May 2015 on land belonging to the Agricultural Cooperative Milevsko, which is situated in the corn-growing area. The trial compared four varieties of sorghum, namely Aristos, Goliath, KWS Freya and KWS Sole. The varieties were sown in different row spacings, namely 75 cm, 60 cm, 45 cm a 30 cm. The samples taken on three dates were analysed for dry matter content. Each variety showed a gradual increase in the dry matter content. During the harvest on 5 October 2015 the varieties KWS Freya and KWS Sole reached an optimal value of the dry matter when planted in all spacings. All varieties produced the highest average yield of green matter when planted in rows spaced 60 cm apart. The variety Aristos produced the highest average yield of green matter. The KWS Sole variety reached the lowest average yield of green matter when planted in rows 76 cm apart. All varieties with 60 cm row spacings, except for KWS Sole, produced the highest average yield of dry matter. The highest average yield of dry matter was reached by Aristos and the lowest by KWS Sole. The results of the one-year trial did not prove a direct connection of the effect of row spacing on dry matter. The effect of row spacing on green and dry matter yield was proved. The optimum row spacing seems to be 60 cm.

Personal Income Tax Harmonization in the European Union
Pavlová, Veronika ; Kubeš, Petr (referee) ; Kopřiva, Jan (advisor)
This thesis deals with the question of tax on personal income harmonization. The introduction will talk about the founding of the European Union and the Free Market and the already existing level of harmonization of tax on personal income. Next, we will talk about the current solvation of this issue. And assess positives and negatives of each variant.

Growing sorghum and maize for forage purposes
KUBEŠ, Pavel
Maize and sorghum are the most important crops worldwide, used for fodder, food and technical purposes. The aim of this thesis is to summarize information about the properties of these crops and possibilities of their usage as fodder plants. The sorghum is compared to determine the effect of the inter-row spacing on the yield of each variety of sorghum plant. The comparison resulted in the statement that the inter-row spacing has a significant effect on the yield of each species. The experiments proved that 12.5 50 cm rows resulted in the highest yields while the 75 cm rows showed decrease in the yields. The qualitative parameters of maize were tested for nutrient composition in relation to dry matter. The sources established that the optimum dry matter of the harvested material ranges between 30 33 %. It is the dry matter when the plants contain water-soluble sugar needed for fermentation process and animal nutrition. These plants also contain sufficiently high proportion of starch. The dry matter of the plant lower than 28 % and higher than 35 % is not suitable for silage.
