Kollár, Milan
The aim of this diploma work is the evaluation of the influence of growing for weed-infestation of beet (sugar beet). The evaluation was carried out in 2021 at chosen pieces of land of PROAGRO company, Inc. and BONAGRO, Plc. in Vyškov region. The evaluation was carried out with the help of numerical method. Three different agro-technical processes of the soil preparation were chosen and then evaluated for the weed occurrence in three different terms. The observation was carried out in three terms. Du-ring the first one, white goosefoot (Chenopodium album) and crumple of Winter Weat (Triticum aestivum) appeared the most. White goosefoot (Chenopodium album), Knot-grass (Polygonum aviculare) and Creeping thistle (Cirsium arvense) appeared the most in the second one. In the third observation I observed weed beet (Beta vulgaris var. Al-tissima). Further I observed the relationship between the intensity of weed occurrence and the technique of the tillage.

Vliv regulačních systémů traktoru FORTERRA 140 na energetické a výkonnostní parametry strojů na zpracování půdy.
Smrček, Jakub
The thesis deals with the current construction of towing equipment with a focus on electro-hydraulic control systems of the three-point hitch of the tractor. In the presented thesis, a methodology for obtaining energy and performance parameters of the plough set is developed for the conditions of a private farm. Based on the proposed methodology, field measurements focused on tractor control systems were performed. The following combination was chosen: 80% force control and 20% position control, then mixed control 50% force and 50% position control and the last 80% position control and 20% force control. The measured and calculated values were tabulated and graphically processed. The performed analysis shows that the measured and calculated values for the individual control systems of the three-point hitch of the tractor decisively influence the energy and performance parameters of the measured ploughing set.
