Management posklizňových zbytků při zakládání porostů obilnin
Fafílek, Viktor
The aim of the bachelor thesis is the study and description of problems of the crop resi-dues during establishment of cereals. The start of this study is focusing on cops residues, their structure and decay. Later is describe disease what survived on crops residuals. The next part of work is it description of influence of pre-crops and their crops residuals to main crop. The Second part is dedicate to soil treatment and guidelines DZES and IOR. In the end of bachelor thesis describe way how to establish cereals of main crops of spring barley and winter wheat.

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

Effect of tillage minimalization technology to control weeds in cereal crops
STEJSKAL, Martin
This diplom thesis deals with the evaluation of quality machines work for soil cultivation used in minimalization soil cultivation technology and weed control in cereal crops. The machines were evaluated for incorporation of harvest residues, uniformity of depth and size of lumps. It was further performed an economic evaluation of selected cost per operation soil cultivation. In order to monitor the development of weeds was based small-plot experiment, where was monitored representation of individual weed species and the effectiveness of selected herbicide.

The use of modern stubble plough with minimum tillage
BARTUŠEK, Marek
The aim of this thesis is to broaden knowledge about the possibilities of using modern stubble plough with minimum tillage in agricultural production. In order to evaluate the work of selected indicators stubble machines was based small ? plot experiments at selected station. The experiment was evaluated lumps, depth of tillage and crop residue incorporation of selected machines. Further economic evaluaiton was carried out operating costs of used machines. The use of machines were evaluated according to the results obtained reccomended in agricultural practice.
