Oil-crops growing in the Czech Republic 1990-2012
HÁVOVÁ, Šárka
The bachelor thesis is the cultivation of oilseeds in 1990 - 2012. The work deals with the biological characteristics of selected species of oil, the quality of oil and its usage. In the other chapters describes the development of crop varieties, cultivation areas, yields and changes in agricultural technology from 1990 to 2012. The oil is described in the work of five major crop producing in the Czech Republic are oilseed rape, white mustard, sunflower, poppy and flax.

Energy using of biomasy from agriculture
ŠPAČEK, Zdeněk
This thesis deals with comparing the suitability of growing grass for energy use over the energy use of the residual agricultural biomass. The thesis includes characterization, agrotechnics, cultivation, harvesting and yield of each crop species and their comparison is shown in several graphic examples. According to the information gathered, maize and sorghum are the most suitable for the production of biogas, especially due to the amount of ?green mass? produced. The most useful for burning is Miscanthus, which is distinguished for its high dry mass yield, immunity to weeds, and the highest heating value and energy yield.

Forage utilization of alternative crops
VOBROVÁ, Petra
Alternative crops are divided into cultural and newly cultivated plants. Growing of these crops was gradually eliminated as the crops had not reached good feeding values. Nowadays, however, they are re-implemented and new kinds and varieties are grown again. The Institute of Fodder Crops is focused on their cultivation and it offers even advisory services. The important thing is to know the appropriate growing method because each plant differs in its demands concerning the location, agro technique and harvesting. The advantage of these crops is that they are undemanding regarding climate and soil conditions. Thanks to their cultivation, they are able to produce high amounts of phytomass with good nutritional value, and thus they can be compared to some traditional crops. The interest in alternative crops is still increasing and therefore the scope of these crops will increase in the future. Out of the chosen crops, I would like to emphasize Lotus cornitulatus, for its high contents of phytomass and an outstanding quality of fodder. Forage quality is one of the best clover, compared Melitotus, which has a bitter taste of her animals forage and therefore does not accept

Sorghum as the energy crop
CIBULKOVÁ, Renata
Sorghum, one of the world's major cereals, is the most commonly used for food or fodder. The aim of this Bachelor thesis is in a form of literary review to summarize information about the properties of sorghum in view of energy use, energy yields, the cultivation technology for energy purposes, the possibilities of using sorghum for energy purposes and the situation in the world and the Czech Republic. Recently sorghum has been tested as a raw material for all branches of the energy industry because of the wide range of potential products such as ethanol, hydrogen, methane, lipids, acetone, butanol and lactic acid. Sorghum can be used as biofuels due to the relatively high yields of phytomass. Utilization of individual species of sorghum depends on their chemical composition that can be significantly influenced by climatic conditions and way of cultivation. Crops improvement plays an important role for increasing production and utilization of this cereal in all climatic conditions.
