Impact of uncoventional technologies of soil cultivation on soil quality
Suchá, Kateřina ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Agricultural land is being handled by various tillage of soil which affects properties of soil. There are two types of tillage treatment. These are conventional (classic) tillage with plowing and minimization tillage (plowing is excluded). The aim of this particular work is to assess the quality of the soil near the village of Bohaté Málkovice, which is being (long-term) handled by minimization tillage. As indicators of soil quality, we used selected physical and physico-chemical characteristics, which are determined from analysis of disturbed and undisturbed soil samples from the top soil layer (0-10 cm) by standard methods in laboratory conditions. The theoretical part describes the basic physical properties of the soil and the ways of their determination. The practical part is devoted to the presentation of the examined locality and the results of selected physical and physico-chemical properties of the soil are presented and subsequently evaluated. In the conclusion, the impact of used tillage in Bohaté Málkovice on the selected soil properties is assessed.

Changes in physical properties of the subsurface soil layers depending on the technology tillage
Bažantová, Adéla ; Larišová, Lucie (referee) ; Kameníčková, Ivana (advisor)
For the correct course of soil processes, plant growth and development is necessary the tillage of soil. Usually we choose between two technologies, that those adjustments are cariied out by. Both are conventional tillage, which uses plowing and minimization tillage, wherein is excluded plowing. Objective of this work is to determine the impact of these tillage treatments on selected physical properties of soil, i. e reduced bulk density of the soil, porosity, momentary contents of water and air in the soil. Soil samples were collected by Kopecky rollers (V = 100 cm3) taken from depths of 0,1; 0,2 and 0,3 m that were used to evaluate. Two samples were collected each July. This period is referred as a critical due to higher soil compaction (movement of mechanization, root system of plants and rainfall totals). Experimental research was conducted in years 2008 – 2011 in the village Bohaté Málkovice.

The effects of different agro-technologies on the soil physical quality in selected localities in the South Moravian Region
Bažantová, Adéla ; Doležal, Petr (referee) ; Kameníčková, Ivana (advisor)
Farmland is being handled by various the tillage of soil especially for the correct course of soil processes, plant growth and development and of course profit. There are two types of the tillage of soil are their conventional (classical) which involves plowing and minimization tillage, where is excluded plowing. The last few decades, the development the tillage of soil focuses on minimization tillage. This includes loosing up small depth, soil conservation tillage and direct seeding. This thesis is aimed at impact of minimization tillage on selected physical and hydraulic properties of the soil. Sampling undisturbed soil samples was performed on the experimental plot Kozlany by Kopecky rollers (V = 100 cm3) from depth of 0 - 10 cm, during the year 2016. On this plot was used minimization tillage in the form loosing up small depth and direct seeding.

Porovnání různých způsobů zpracování půdy ke kukuřici na zrno
Špunar, Michael
The bachelor thesis concerns with comparison of soil cultivation technoologies and their influece on yealds of grain corn. Whole thesis is based on one year field trial, which was realised in years 2016/2017 by company ZEV Šaratice. The goal of the trial was to compare conventional tillage and minimum tillage. Parts of the field cultivated by both technologies were seeded with three hybrid varieties and evaluated in four repetitions. Research presents possibilities of soil cultivation and general information about sweetcorn growing. In the second part of the thesis, there are statistically evaluated results of the trial, which did not prove any statistically provable difference in any cattegories.

Vliv nových technologií pěstování kukuřice na zaplevelení =: The impact of new cultivation technologies on the weed infestation in maize /
Chovancová, Světlana
This study assessed the impact of using different cultivation technologies on the weed infestation in maize growths. Maize has been evaluated in three experimental sites, Žabčice, Višňové and Skalice (all located in South Moravian region, Czech Republic). Observation of selected sites and overall evaluation of performed experiments was carried out during 2012 and 2016. The weed infestation was evaluated by numerical methods where the number of individual weeds was counted in each tillage treatment of monitored plots on 1 m2 in several repetitions. The data obtained was processed by classical statistical methods in addition to multivariate analyses of ecological data; the Redundancy Analysis (RDA) or Canonical Correspondence Analysis (CCA). Our results show that cultivation technology clearly affects the intensity of weed infestation as well as the species spectrum of weeds in maize. Particularly, the reduced soil tillage creates space for higher representation of new and unusual weed species. Concurently, it has been also confirmed that the weed occurence in maize significantly reduces the development of crop biomass and grain yield. An understanding of the effect of maize cultivation technologies on weed infestation allows flexible adjustment of appropriate weed control or will adjust the overall chemical control.

Evaluation of tillage effect on seed yield of winter oilseed rape
TOMÁŠEK, Václav
This thesis was elaborated as a literary overview dealing with the issue of the tillage effect on seed yield of winter rape. First of all, thesis describes the development and importance of winter rape cultivation, its use in individual sectors (food, feed, oleochemistry and energy use). Next it describes the morphological structure of rape, its biological characteristics and some of its varieties. The second part of the thesis deals with the tillage effect on seed yield, development and character of winter rape root system. This part is focused on the classical tillage system that uses plowing and the minimum tillage system including for example conservation tillage, no-tillage and strip-tillage.

Stanovení množství posklizňových zbytků v osevním postupu v podmínkách hospodaření se živočišnou výrobou
Barteska, Tomáš
The dissertation focuses on issue of a post-harvest residues in the crop rotation. The paper describes methodology of setting up the experiment, measurements, collection and analysis of samples. Also available is a characteristics and climatic conditions of the experimental locality. The amount of post-harvest residues were followed up for 3 crops (winter wheat after alfalfa, winter wheat after maize and spring barley after sugar beet) for three variants of tillage and three sampling depths. From these selected the most post-harvest residues 24.98 t.ha-1, was left by winter wheat grown after alfalfa sown variant with direct seeding. The smallest amount of 13.02 t.ha-1 was measured for spring barley after method of minimization. Option of plowing for wheat after alfalfa and wheat after corn reached was measured by average of 17.5 t.ha-1. Average amount of underground biomass of all crops without distinction in processing variations was resulted at the depth of 0 - 0.15 m amount of 10.03 t.ha-1. At a depth of 0.15 to 0.30 m, it was 2.84 t.ha-1 and at a depth of 0.30 to 0.45 m - 2.40 t.ha-1. The total amount of post-harvest residues (underground biomass + straw stubble) Winter wheat was grown after alfalfa - 21.25 t.ha-1, winter wheat after corn - 18.77 t.ha-1 and spring barley after sugar beat - 13.45 t.ha-1. The results of dissertation showed a significant difference according the results listed in the literature sources. This could be due to the influence of the year, which was extremely profitable and may also be influenced by the selection of representative localities, because the sample taken represents only a small portion of the total area
