Comparison of tillage technology in growing crops in the business of agricultural production
KULÍK, Jan
When soil tillage is possible to use several technologies . In business, ZD Trhový Stepanov a.s.. the use of technology plough (plow) and minimazation (deep loosening) . For each of these types was performed characteristics of individual elements lines and were also calculated their efficiency. In another part of both technologies have been economically evaluated and then compared the cultivation of winter rapeseed and winter wheat in 2013 and 2014.

Reaction of selected varieties of potatoes on the amplion of foliar fertilizers
KULÍK, Jan
The aim of the experiment was to evaluate the reaction of chosen potato varieties to the application of leaf fertilizers. The speed of their action and, together with combination with other interventions (common application with fungicides), and also the economics of their application belong among the advantage of leaf fertilizer application. In 2012 and 2013 there was an experiment established in 380 m above the sea level. In this experiment the effect of application of urea solution, Lignohumate, and Energen Fructus was evaluated in the varieties with a different length of vegetation period Magda very early, Adéla - early, Laura and Satina semi early and Bionta - late. The rate of sprouted plants, the yield of tubers, the proportion of tubers of consumer size, the number of tubers under cluster, an average weight of one tuber, the number of stems per a plant, and the content of starch were evaluated in these plants. It was found out from the results that in 2012 Magda and Satina varieties reacted with an increased average weight of one tuber after the application of all leaf fertilizers. The effect of Lignohumate was the most positive in this year; it increased an average weight of one tuber in Magda, Adéla, and Satina varieties. In comparison to that, in the second year of the experiment there was a positive reaction to additional fertilizing with Lignohumate, Urea, and Energen Fructus, leading to the increase of an average weight of one tuber in Magda, Adéla, Laura, and Bionta varieties. In 2013 there was the highest influence on an average weight of one tuber caused by the use of Urea, namely in Magda, Adéla, Laura, and Bionta varieties.

Rating of automotive transport system with swap bodies in the business of agricultural production.
KULÍK, Jan
This thesis deals with the evaluation of automotive transportation system with swap bodies in the business of agricultural primary production and the possibilities of its use. The Automotive transportation system can be the carrier system for several kinds of extensions because of its design. In this case, the investigated transport system in selected company uses the back of the bulk materials, tanks and bulk truck. It was the truck LIAZ 151 with hull CSAO for bulk materials, faecal tank ACF 041 and high-volume hull type for transport bulky feed. Operating and investment costs of the whole transport system, performance of each swap bodies and technical parameters were evaluated. The primary agricultural enterprise ZD Trhový Štěpánov, a. s. was also characterized. For this thesis were detected information by observing and processing time of each frame bodies. More information has been gathered from internal materials, such as a serious journal, time sheets, annual report and other enterprise data sources. In terms of economic costs, these costs have been identified - costs per km = 27,91 CZK/km, costs per tonne transported = 52,93 CZK/t and costs per tonne-km = 7,46 CZK/tkm. Total operating costs amount is 702 243.62 CZK. Another result of the investigation was determined consumption and annual use of individual bodies. For the bucket SCAO was found that the consumption is 0,69 litres per tonne transported and annual use of individual bodies is 98 days. For feacal tank ACF 041 the consumption is 29.1 liters per hectare applied of manure and Antal use of individual bodls is 98 days. The consumption of bulk superstructure is 0.93 liters to be transported tonne and was used for 34 days.

The influence of leaf fertilizers at potato yield
KULÍK, Jan
The aim of this thesis is to evaluate the influence of leaf fertilizers at potato yield. The main advantage of leaf nutrition is speed of an action on a plant, possible combination with other interventions (application of fungicides) and economy of use. Leaf nutrition promotes tuber yield and quality, mainly in their tuber set and poor growth conditions. It is important to perceive leaf nutrition as a suplement nutrition because it is no substitute for root nutrition. The field experiment was established on the land of the University of South Bohemia in České Budějovice in 2011. There were used selected varieties of potatoes with different growing season. Very early variety Magda, early variety Adéla, semi-early varieties Laura and Satina and serotinous variety Bionta. The experiment was comprised of four variants and in four replications. There were used liquid solution of urea, Lignohumate and Lignohumate with NPK for fertilizer of variants 1, 2 ,3. Control variant was without aplication of fertilizer. There were evaluated proportion of grow-up plants, tuber yield, proportion of ware size tubers, the number of tubers per plant, the average weight of one tuber, the average weight of ware size tubers and starch content. It was found out using of liquid solution of urea increased tuber yield of all selected varieties. The highest yield of varieties Adéla and Laura was achieved by application of Lignuhumate, the highest yield of varieties Satina a Bionta after using of liquid solution of urea. Very early variety Magda was not too responsive to application of leaf fertilizers excep using of liquid solution of urea.
