Využití bezpilotního průzkumu pro cílenou aplikaci herbicidních látek
Panteleev, Evgeny
The thesis "the use of unmanned Exploration for targeted application of herbicides" is focused on the analysis of land data using unmanned Exploration for the following application of herbicides. The theoretical part of the thesis contains a description of common methods for assessing the state of stands in the form of remote sensing. And then it deals with sub-methods, herbicides and drones. The practical part deals with a semi-operational field experiment in the locality of Letkovice. The content includes the results of field and remote sensing, analyzed data from GIS and results of field experiments focused on variable applications of herbicides. And gave an economic comparison of uniform and variable methods of management.

Rozdíly v zaplevelení širokořádkových a úzkořádkových plodin
Kubínek, Marek
The task of this bachelor's thesis was evaluate weeds and evaluate the differences in weeding of narrow-row and wide-row crops. The evaluation took place on the land of AGROPOD Podolí a.s. and at the private farmer Ing. František Kubínek. Weeds were observed per 1 m2 in winter wheat, spring barley, maize and annual sunflower. The results were statistically evaluated using canonical correspondence analysis (CCA). In narrowrow crops, weeds were recorded mainly from the families Asteraceae, Chenopodiaceae, Convolvulaceae and Violaceae. These species were mainly creeping thistle (Cirsium arvense), white goosefoot (Chenopodium album), wild buckwheat (Fallopia convolvulus), field pansy (Viola arvensis) and others. Weed species of the families Chenopodiaceae, Asteraceae Asteraceae and Convolvulaceae have been found in broadleaved crops. The most common were white goosefoot (Chenopodium album), creeping thistle (Cirsium arvense), wild buckwheat (Fallopia convolvulus) and others.

Analýza složení plevelové vegetace na železnici
Ševčíková, Silvie
The main goal of this thesis was to analyze the composition of weed vegetation on the railway. Selected sections of railway lines were Brno Main railway station and its ancillary operations. Observations were made on five different sites, on the embankment, on tracks, in the no used track, on places between rails and buildings. Vegetation was evaluated by using vegetation of fytocenological plots. At each station were carried out three plots. The first evaluation was in July and the second one in September 2013. Monitoring were statistically processed by analysis DCA and CCA. On the selected section of the railway was sighted a total of 49 kinds of plants. The highest ground cover species were Ailanthus altissima, Achlea millefolium, Arctium tomentosum, Arrhenatherum elatius, Digitaria sanguinalis, Echium vulgare, Equisetum arvense, Parthenocissus inserta, Sambucus nigra and Viola arvensis.

Hodnocení zaplevelení vybraných porostů cukrové řepy
Kollár, Milan
The aim of this bachelor thesis is to evaluate the weeds of selected growths of sugar beet. The evaluation was carried out in 2018 and 2019 on selected plots of PRO-AGRO, spol. s r.o. in the district of Vyškov. Weed evaluation on selected plots was performed using numerical method. Three observation and evaluation dates were esta-blished, first one after sowing and at the time of emergence, second before 2nd or 3rd herbicide application and the last one through August to September. The most common occurrence in the first observation period was crumble of Winter Weat (Triticum aesti-vum) a white goosefoot (Chenopodium album). In the second term, the occurrence of Lambs Quarters (Chenopodium album), the Fool’s parsley (Aethusa cynapium) and the Comfrey medical (Symphytum officinale) were observed, while in the third term the biggest issue was weed beet (Beta vulgaris var. altissima).

Analýza druhového spektra plevelů polních plodin v zemědělském podniku
Chalupová, Lenka
The aim of this thesis was to evaluate the spectrum of species and the abundance of weed infestation in the selected company. The measurements were performed on the land of AGRAS Bohdalov, Ltd., located in region Vysočina and farms on 1,280 hectares of land. The evaluation was carried out in two crops: winter wheat and spring barley after various preceding crop. For evaluation there was used a numerical method; on quarter m2 with a conversion to 1m2. In winter wheat was found 19 weed species. The most abundant were Field pansy (Viola arvensis), Ivy-leaved speedwell (Veronica hederifolia) and Goosegrass (Galium aparine). In the cover of spring barley were found 15 weed species. The most common were Field pansy (Viola arvensis), Field pennycress (Thlaspi arvense) and Shepherd's purse (Capsella bursa-pastoris).

Vliv technologie pěstování kukuřice seté na množství organického uhlíku v půdě a kvalitu půdní organické hmoty
KADLEČEK, Ondřej
The aim of the diploma thesis entitled "Influence of maize cultivation technology on the amount of organic carbon in the soil and the quality of soil organic matter" was a comparison of quantity and quality non - humidified soil organic matter in various maize cultivation technologies. The work included not only literary research, but even field experiment, thus regular soil sampling, their processing and subsequent analysis. The theoretical part was focused on growing corn in the conditions of the Czech Republic, description, division and importance of soil organic matter, methods for determining its quality and quantity. The practical part dealt with the establishment of a field experiment of maize, soil sampling, their processing and analysis. The obtained values were used to determine the amount and quality of the primary soil organic matter, which was expressed by the rate constant of its oxidation. The obtained data were statistically evaluated in the program STATISTICA 12. The effects of sampling dates, weed control methods and fertilization variants on various soil characteristics were determined.

Biology and control of weeds in root crops (Solanum tuberosum Wild.)
SAMOHEJL, Petr
In the theoretical part, agricultural techniques in the cultivation of potatoes were described and selected weed species were characterized, those that cause damage not only regarding root crops. Chemical protection is currently considered to be an important and most represented method for the regulation of weed species. It resides in the use of plant protecting herbicide products to limit the population of weed species below the economic hazard threshold. The practical part of the bachelor's thesis is focused on monitoring the biology and regulation of weeds in the cultivation of root crops (Solanum tuberosum Wild.). On an experimental plot of land managed by the Samohejl family near the village of Malešice (district České Budějovice) in the South Bohemian Region. Three potato varieties (Adéla, Belana, Marabel) and three different herbicides (Arcade 880 WG, Mistral and Sencor Liquid) were compared and the yield of tubers of cultivated potato varieties was monitored at the same time. The results showed that the effect was different for each herbicide. Due to their active substance (metribuzin), the small effect of these products was manifested on sow thistle and creeping spider. As a secondary result, the yield of tubers of individual varieties of potatoes in different treatments was monitored, when individual varieties responded to different herbicide treatments and thus provided different yields in these cases.
