Three the most cultivated legumes in the Czech Republic with soil conservation technologies
Koukolíček, Jan ; Pulkrábek, Josef (advisor) ; Milan, Milan (referee)
The experiment which was done on the fields of Cooperative farm in Nečín should verify three soil conservation technologies with three most cultivated legumes in the Czech Republic. We tested deep cultivation, shallow tillage and no--tillage technology. And we used winter pea which was seeded in two terms in the autumn and in the spring. Spring pea, narrow- leafed lupin, white lupin and soya were seeded only in the spring term. We tested soil density and soil moisture with different soil conservation technologies. We observed vegetation stages and we made pre--harvest and post--harvest evaluation.

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.

Production and processing of seed potatoes in organic farming
Janochová, Veronika ; Dvořák, Petr (advisor) ; Koukolíček, Jan (referee)
Farmers working by the organic farming system are, according to valid legislation, required to use preferably certified ecological planting material. According to the zero offer of those products present this Bachelor work evaluate the possibility of seed potatoes (Solanum tuberosum L.) in organic farming system. The most common reason of not accepting planting material is the medical condition, that is affected during the entire production process. Most prominent problem is incidence of viral diseases in the mother crops, that are mostly transmitted by aphids (Aphidoidea). Recommendation for successful planting of seed tubers is a complex of preventive measures along with the whole process from its zoning, land cultivation, potato seed preparation through the vegetation and plant care to the harvest process and subsequent treatment of tubers. Part of the work is devoted to the regulation of harmful agents using bioinsecticides, plant extracts or growing potatoes with the use of intercroping. The practical part evaluates the posibility of growing buffer strips with the use of buckwheat, oats and mixture of plants (mustard, phacelia, buckwheat and sunflower) as a possibility to reduce flight activity of aphids in potato fields. Obtained results may indicate an influence of border crop to incidence of aphids and its specific effect could be caused by kind of buffer strip plant or its mixtures
