Porovnání různých technologií setí řepky ozimé
 Chrastinová, Nicole
Winter rape is a crop that we cultivate both in traditional and minimizing technology. The economy of minimizing technology is hidden in the high performance of shallow soil tillage machines. If we want to have a well-established growth we have to deal with these problems: suitable bulk weight of soil and size of soil aggregates, good processing of post-harvest residues, prevention of weed growth and sowing in the right agrotechnical term with seed distribution according to sowing technology.

Vliv přesného setí na kvalitu založení porostu a výnos ozimé pšenice
 Kopecký, Petr
The Master thesis contains literary review and practical evaluation of the field research by two technologies of seeding. The first part of the literary review describes seeding of the wheat. Next part mentions the issues density and the competitiveness of the crop stand. Following chapters describes the seeding to the line and the precision seeding. Next chapter describes equipment for the precision drilling. Practical part of the thesis describes the research started 2014 in the school research station in Žabčice. In the research were used the varieties of the winter wheat Bohemia and Tobac. They were drilled by the pneumatic seeding-machine and by the seeding-machine prototype Farmet for the precision drilling of cereal. In the research was also evaluated the influence of the seed quantity, seeded in 4 variations from 1 up to 4 million grains for hectare.

Precision sowing and the establishment of grain crops
 Brinar, Jan ; Pulkrábek, Josef (advisor) ; Koukolíček, Jan (referee)
The object of the study was to compare the classical method of planting (small-plot complete seeder) and precise seeding for a given distance (prototype seed sowing machine FARMET for sowing with fertilizer under the heel) for winter wheat. Chosen were various seeding rates for precision and classic sowing machine into the cereals. Tested were sowing rates from 1.0 to 4.5 MKS. The experiment was done in the period 2014,2015 at the research station CUA in Prague-Uhříněves. The chosen variety was forage winter wheat Penalty quality C from PROBIO of 2014. For the basis of the hypothesis was selected seed rate of 2.0 MKS in precision sowing against 3.5 MKS in a classical way of sowing. The goal was to determine whether the reduced seed rate during sowing precise manner provides the same yield as a recommended seed rate of a traditional methods of seeding. The forecrop was a spring barley. Soil was prepared using the minimize blade cultivator before sowing of the wheat. Some variants of the experiments were fertilized at planting to promote germination. These variants were fertilized with 150 kg N / ha freely to the soil before sowing or 150 kg N / ha under the heel when sowing fertilizer Nitrophoska perfect. Furthermore, all plots were fertilized with 140 kg N / ha in three divided doses in a LAD 27, without distinction. Dry summer in 2015 hadn´t a devastating effect on wheat and most variants of the experiment gave a very good yield. The assumption that there will be savings precision sowing seed while preserving the yield was confirmed. Additionally it was shown that precise sowing on average in all variants seeding rates, fertilized before sowing or not surpassed yields of classic seeder.
