The influence of nitrogen on yield formatin of spring barley
JANUROVÁ, Eliška
The purpose of this diploma thesis was to find out the effect of a graduated dose of nitrogen fertilization on the revenue elements (number of plants per area, number offshoots per area, number of ears per area, number of grains inside one ear and weight of thousand seeds) of the spring barley. The field experiment was established in the spring of 2021 on a private family farm which belongs to Mr. Jaroslav Čech and it is located in Běleč near Mladá Vožice. Spring barley of the Bente variety was sown in the experimental field. The experimental doses of nitrogen fertilization were determined as follows: 20 kg. ha -1,50 kg. ha-1, 80 kg. ha-1, 110 kg. ha-1. The evaluated data were processed and recorded into tables and graphs in the results chapter. The highest revenue elements were reached in the variant IV, where was applied 110 kg pure nutrients of nitrogen fertilizer. The revenue elements in individual variants were decreasing with decreasing dose of nitrogen fertilization.

Evaluation of yield parameters and first pod height in soya bean (\kur{Glycine max} L.)
DOLEŽAL, Jiří
This work deals with the influence of the growth regulator on soybean vegetation. The main part of the diploma thesis is the evaluation of individual parameters of selected varieties. For this purpose, a pilot experiment was established in 2019 in the Benešov region in location Netvořice. This area is located in a moderately warm climate area in the area of potato production at an altitude of 390 meters above sea level. Two very early soybean varieties, Amandine and Abelina, were selected for this experiment, which are suitable for these conditions due to their shorter growing season. These varieties were grown in two variants. Control variant without treatment and variant with treatment with Energen Apikál, which increases apical dominance. Each variant and treatment variant was repeated 4 times to obtain the most accurate data. The following parameters were evaluated for both varieties: seed yield, nitrogenous substances content, number of plants per square meter, fat content, weight of a thousand seeds, plant height, number of primary branches, number of pods per plant, number of seeds in the pod and height of first pod. The highest average yield was achieved by the Amandine variety in the treated variant 3.49 t/ha. The Abelina variety achieved a very satisfactory yield of 3.18 t/ha also in the treated variant. In the untreated variant, these varieties also achieved a satisfactory yield. Amandine variety 2.99 t/ha and Abelina variety 3.06 t/ha. Another parameter determined was the nitrogenous substances content. This indicator also showed an increase in nitrogenous substances in the seed in the treated variant in both varieties. A very important monitored parameter was the height of the first pod from the soil surface. Here, after the application of Apikál, the lower floor of the pods increased by approximately a centimeter compared to the control in both varieties (Amandine 10.68 cm and Abelina 11.88 cm). In conclusion, Energen Apikál has a positive effect on both qualitative parameters and the main yield elements, which favorably affects the yield and, together with the higher location of plant pods, also partially minimizes harvest losses.

Evaluation of effect of selected physiologically active substances on grain yield and its structure in model winter wheat cultivar
MACHOVÁ, Klára
The main topic of this bachelor thesis is the evaluation of effect of selected physiologically active substances on grain yield and its structure in model cultivar of winter wheat. For this purpose it was founded a one-year small-land experiment on the land of the experimental station Lukavec, in september 2016. For this experiment, have been selected a physiologically active substances, with components of humic substances character. The experimental variants contained, separately and in combination, the commercial product ENERGEN FULHUM PLUS and the physiologically active substance named Lignofen. For this experiment, it was selected the winter wheat variety Pannonia. The influence of these applications was evaluated in parameters of actual yield and yield components creation, which is - number of ears, number of grains per ear, and weight of a thousand grains. Further, was evaluated the influence of these applications on grain quality parameters, which is - amount of N-substances, Zeleny sedimentaition velue, falling number, amount of gluten, Gluten index and volume weight.

PĚSTOVÁNÍ PŠENICE V SETRVALÉM ZEMĚDĚLSTVÍ
PETÁKOVÁ, Šárka
The aims of the bachelor study titled Wheat Production in Sustainable Agriculture were to compare wheat production levels of organic and conventionally managed fields, namely, to assess the influence of the fertilization regime on the formation of yield elements and also, to assess the overall yield ability of selected winter wheat varieties. A small field with winter wheat varieties located on the university grounds was used as an experimental site for this study. The site is located in Ceske Budejovice in South Bohemia at an altitude of 380 m, with average annual temperature reaching 7.8 °C and with the average rainfall of 620 mm. Four varieties (two hybrids nad two lineages) were examined under three different fertilization treatments: no nitrogen fertilizer, nitrogen fertilizer and organic fertilizer (clover-based). The study has found that the choice of the variety appears to have most impact on the overal yield. Hybrid varieties outperformed lineage varieties in overal grain yield, despite the fact that lineage varieties produced higher results in regard to the following yield factors: the number of plants, offshoots, ears, grains in the ear per m2 and weight of 1000 grains. The choice of fertilization treatment seemed to influence the crops outcomes less substantially than the choice of the variety per se. While the influence of the fertilization treatment was secondary, nitrogen-fertilized plots produced the highest grain yields (7,78 t.ha-1),, organic fertilization (clover) produced average results (7,59 t.ha-1), and the the lowest yield has been predictably produced in non-fertilized site (7,05 t.ha-1).

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.
