Yield formation and quality of spring naked and hulled barley
MAREK, Jan
On the grounds of the South Bohemian University was founded in 2015 oneyear experiment. In this experiment we compared three classical and one naked variety of spring barley. Each variety were planted in four replications. For each repetition was assessed the number of emerged plants, number of tillers, number of ears, yield, thousand grain weight, the proportion of leading grain, density andcontent of nitrogenous substances. The average yield of the hulled varieties exceeded 6 t/ha, while in the nudevariety was 4,68 t/ha. The nude variety also showed the lowest HTZ, highest densityand the highest content of nitrogenous substances.

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.

Yield formation of spring wheat
BAŽANTOVÁ, Eva
The theme of these Thesis - Yield formation of spring wheat - presents a comparison of selected varieties of spring wheat, which are grown in the Czech Republic. The field trials were set up in 2012 on the experimental area of the Faculty of Agriculture, University of South Bohemia in České Budějovice. In four replications was planted eight varieties of spring wheat - Corso, Brawura, Aranka, Tercie, Granny, Scirocco, Septima a Vánek. Results of spring varieties were compared with a control winter variety Baletka. During the vegetation was monitored weeds, diseases and pests and evaluated the number of plants. In the final section are evaluated yields main elements - number of spike per square meter, number of grains per spike, thousand grain weight. The yield, theoretical yield, spike lenght and density is presented there too. The average number of spikes in spring varieties reached of 520 pieces per square meter and control winter varietiy reached 491 pieces per sqare meter. Number of grains per spike was average 45 pieces and control winter variety was 37 pieces. The average thousand grain weight of spring varieties amounted to 31,7 grams and was comparable with the results of control winter variety.

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.

Yield formation of winter wheat depending on row width in ecological agriculture
PROCHÁZKOVÁ, Lucie
The Subject of diploma work: Yield formation of winter wheat depending on row width in ecological agriculture This work deals with the formation of winter wheat yield. Winter wheat was cultivated on the narrow and wide rows to field experiments. The attempt was focused mainly on creating yield components (number of plants per square meter, number of grains per spike, the weight of one thousand grains). There was also accomplished the verification during the vegetation and there was the comparison of the theoretic and real yield at the end.

Yield formation of winter wheat in ecological agriculture
ŠEBESTOVÁ, Martina
The diploma thesis "Yield formation of winter wheat in ecological agriculture " is focused on classification of genotypes of bread wheat on the basis of the morphological characters and yield output of bread wheat in ecological farming system. The field trials were set up by using the method of random blocks in the years 2005 and 2006 on the experimental area of the Faculty of Agriculture, University of South Bohemia in České Budějovice. 10 Austrian genotypes of bread wheat were tested: Capo, Ludwig, Clever, Eurofit, Element, Eriwan, SE 408/04, SE 320/05, SE 304/05 a SE 322/04. The results are focused on the postharvest analysis the main yield components {--} number of spike per square meter, number of grains per spike, thousand grain weight (TGW). The yield and theoretical yield is presented there too. The number of grains per spike, the level of yield and TGW were relatively high. On the other hand the number of spikes per square meter doesn´t reach to expected value in ecological farming. The results were analysed by ANOVA of main effects in programme Statistica. The tested Austrian genotypes showed the possibility of using them in the conditions of ecological farming in the Czech Republic.
