Porovnání vybraných odrůd pšenice podle jejich schopnosti regulovat a kompenzovat výnos v odlišném prostředí
Brtníková, Daniela
This diploma thesis presents the results of experiments monitored in the 2020/2021 and 2021/2022 growing seasons at three experimental locations in the Czech Republic. The chosen locations were Obora and Písky, which belong to the Žabčice Field Experi-ment Station, and the site in Prague-Ruzyna belong to the Plant Production Research Insti-tute, v. v. i. These locations are different mainly in terms of climate and soil conditions. The monitored varieties were Balitus, Bohemia, IS Conditor, RGT Sacramento, Tobak, Tonnage and Tybalt. For these varieties, yield components (number of spikes per m2, number of grains in spike and one thousand grain weight) were evaluated and their evaluation in rela-tion to the yield and harvest index together with the compensatory and self-regulating abili-ties of wheat. A statistically significant effect of variety, location and year was recorded for most of the evaluated parameters. The best-rated varieties for the monitored period were the Tonnage and Tobacco varieties, which achieved above-average yields and showed certain abilities of compensation and plasticity to growing conditions. On the contrary, the worst rated was the Bohemia variety, which, despite the high grain weight, achieved below-average yields compared to the other varieties.

The oat growing in terms of selected agricultural company
ZIMMERMANNOVÁ, Zlata
The aim of the dissertation thesis was to find out the influence of fungicide and increased amount of nitrogen on the yield components of oat. The dissertation is divided into a literary overview and the thesis as such. In 2018 a pilot research was made on the land of a farm located in the district of Tábor. Atego oat was grown in four variants there: a control variant, a variant fertilized by nitrogen (without the usage of fungicide), a variant comprising fungicide application (without nitrogen fertilization) and a variant including both nitrogen fertilization and fungicide application. The highest theoretical yield was registered in the variant which contained fungicide as well as nitrogen. Regarding the yield components of oat, the highest number of plants and panicles was registered in the variant fertilized by nitrogen (without the usage of fungicide); the highest number of stolons and the maximum weight of one thousand grains was measured in the variant including both nitrogen fertilization and fungicide application. Finally, the highest number of grains in a panicle was obtained from a control variant.

Technologie pěstování a vliv hnojení N na výnos silážní kukuřice
DOLEŽAL, Jiří
This bachelor thesis deals with the influence of nitrogen on the formation of yield components in maize. The entire work is divided into two parts, a theoretical part and practical part. In the theoretical part of the corn I characterize morphological and botanical point of view. Further described technology of growing maize. In practical part I describe the methodology and workflow. For this work were selected two maize hybrids. I fertilized this hybrids with conventional nitrogen fertilizers. In conclusion, I compare the results of yield componets both varieties and profitability of individual variants.

Vliv kvality osiva na polní vzcházivost a výnos pěstovaných obilnin.
KÁRNÍKOVÁ, Martina
The Bachelor thesis is focused on seed properties germination capacity, 1,000-grain weight, moisture in spring wheat Epos and Vánek and in spring barley Aktiv and Bojos. Laboratory tests were carried out in the analytical laboratory SEED TEST Planá nad Lužnicí. Samples for analyses were taken in ČSO Pacov and all parameters complied with requirements for certified seed. Each of the grain varieties from the same lot was sown in three fields owned by agricultural cooperatives and private farmers. Some basic yield components a number of plants per m2 and a number of ears per m2 were monitored and evaluated in the fields during the growing season. Yields from each field and 1,000-grain weight were determined after the harvest.

Evaluation of grain yield components in selected winter wheat cultivars
ZELINKOVÁ, Monika
This thesis deals with the yield ability of chosen winter wheat varieties during growing season 2014/2015. Comparison of the two varieties (hybrid and linear). The experiment was established in standard and reduced seed rates and also in four replicates on the plot of Faculty of Agriculture, University of South Bohemia in České Budějovice. Were examined yield components: the amount of spikes per 1 m2, amount of grains per spike and weight of thousand grains. During the vegetation observed were the amount of plants per 1 m2, each growth phase, the number of stalks per 1 m2 and plant height. Furthermore, measured were amounts of units of chlorophyll in plants using device N-Tester and the SunScan device sunlight usable for photosynthesis of plants wherein the processed values of leaf area index (LAI). At the end, compared were the theoretical and real yield and evaluated were spike length, amount of spikelets in spike and density.

Yield formation of winter wheat
ŠEVČÍKOVÁ, Tereza
This thesis deals with yield formation with the 12 varieties of winter wheat during growing season 2013/2014. The experiment was established in four repetitions on the plot of Faculty of Agriculture, University of South Bohemia in České Budějovice. Examined yield components were the amount of spikes per 1 m2, amount of grains per spike and weight of thousand grains. Furthermore evaluated were the amount of plants per 1 m2, amount of spikelets in spike, real and theoretical yield, spike length and density. The next step was the processing of the results where the average value of all the varieties in the amount of ears per 1 m2 was 783 units/m2. The second element of the yield varieties reached the average number of grains per spike 36.2 pieces. And the mean weight of´thousand grains was 44.42 grams.

The comparison of winter wheat yield ability
AMBROZOVÁ, Lucie
The topic of this Diploma Thesis is "The yield ability comparison among varieties of winter wheat". The Thesis dealt with the yield ability of chosen winter wheat varieties grown in the Czech Republic. Twelve varieties were chosen for the measurement purposes. The experiment was done with kind cooperation with the South Bohemia University in České Budějovice, faculty of Agriculture during growing season 2011/2012 and 2012/2013 on its own land. The experiment was focused especially on the yield components creation number of ears, number of grains per ear, and weight of a thousand grains. Among those, the incidence of weed, diseases, pests were observed during the vegetation period. The number of plants and offshoots were rated. At the end, the theoretical and actual yield, ear length, and volume weight were compared.

The comparison of winter and spring wheat yield ability
AMBROZOVÁ, Lucie
The theme of this Bachelor's thesis is to compare the productivity of the variety of winter and spring wheat. This report deals with the earning capacity of selected winter and spring wheat varieties. There were a total of eight selected varieties, 4 of winter- and 4 of spring. The experiment was conducted on the grounds of the South Bohemian University in Ceske Budejovice. The first part of the experiment was focused on the control during the growth, the second part documents the analysis of examined samples (ear length, number of grains per ear, weight of thousand grains and the volume density).

Growing of wheat in NORI, k. s., ZD Přešťovice and Farm - Administration
KŘIVAN, Václav
Aim of this bachelor theses was to investigate differences between technological processes of winter wheat cultivation on selected varieties grown on farms Nori, k. s., ZD Přešťovice and Farm Administration s. r. o. Varieties with similar attributes were selected and yield components (such as number of plants per square meter, number of spikes per square meter, number of grains in the spike and weight of one thousand of kernels) were studied. Samples of monitored wheat varieties were collected and bulk density was determined. The obtained results were statistically evaluated and discussed. Obtained data were used for recommendations. All selected varieties achieved higher yields compared to the national average on monitored farms with one exception - variety Cubus on Nori farm.
