Vliv vybraných podmínek pěstování na výnos rostlin "microgreens"
FILIP, David
This bachelor's thesis deals with the cultivation of microgreens plants, focusing on the quest for an optimal growing substrate in terms of yield elements. The practical part of the thesis evaluates the influence of four selected growing substrates on the quantity and content of pigments in the produced biomass of three different micro-greens. To ensure result comparability, the plants are cultivated under defined con-ditions in phytotrons. Additionally, the thesis outlines the financial implications of cultivation on various substrates. The research also indicates that the optimal sub-strate for plant cultivation, based on the compared yield elements and the compared growing substrates, is the garden substrate Agro CS Natura. Similarly, plant produ-ction is most cost-effective when using the Agro CS Natura substrate.

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 yield formation of spring wheat in depending on preceding crop
ŽÁČEK, Josef
This diploma thesis deals with the comparison of the influence of three different pre-crops on the spring wheat growing in real conditions of a chosen agricultural business. In 2018, a pilot plant test was established on the property in KÚ Dolní Svince, č.p. 0802/23 with the total area of 13,19 ha. For the establishment of the pilot plant test, an area of 5 ha had been used, which, due to its position, occupied the area of all thre pre-crops (corn for silage, winter barley, winter triticale). During the vegetation period, the occurence of weeds had been monitored and the crop yield elements for all stages of all spring wheat had been evaluated. After the harvest, the real crop yield of the wheat had been evaluated and a final economical evaluation had been made. The average crop yield concerning the first option, (pre-crop corn for silage) reached the yield value of 5,65 t.ha-1 , which was a 0,42 t.ha-1 more than the second option (pre-crop winter barley), in which case the value of harvest was 5,23 t.ha-1. Concerning the third monitored option (pre-crop winter triticale), the harvest value was almost similar to the second option - 5,36 t.ha-1. The most suitable pre-crop for the highest harvest of spring wheat is corn for silage, which has reached the highest profit when compared to the other options. In spite of a less advantageous pre-crop, the third option reached the highest-quality of nitrogen and nitrogen compouns.

Vliv hustoty výsevu na výnos u vybraných odrůd jarních obilnin
ŠÍR, Josef
Bachelor thesis focuses on cereals and their significance, individual phases of basic soil treatment, creation of economic yield, weeds and chemical means to regulate them. The aim of the work is to extend knowledge about factors that affect the density of sowing of selected varieties of spring cereals. In order to determine the impact of different density of sowing on the elements of the yield structure of the following varieties of spring cereals - wheat Kabot, barley Manta, barley Kvorning, barley Vendela, oats Poseidon and oats Ozon was founded an attempt at the school farm of SOŠ zemědělská Tábor. During the growing season, the basic yield elements were evaluated on the plot of land - the number of plants per m2, the number of ears per m2. During vegetation, the presence of weeds in cultivated spring cereals was discovered. During harvesting, the yield of the various varieties of spring cereals was examined.

The yield formation of oil flax
PAVLÁTOVÁ, Kristýna
The aim of this thesis was to asses the production of yield of chosen varieties of flax. Six varieties of oil-flax and one variety of fiber-flax was involved in this thesis. The observation took place in 2016 and was focused especially on the main yield elements, precisely on the number of plants per meter square, the number of capsules on the plant, the number of seeds in the capsule and the weight of one thousand seeds. As a complementary value was determined total and technical lenght of plants. The discovered values was compared reciprocally and interpreted graphically. Then, the appearance of injurious agents in the stand was monitored. It is obvious from the results, that the yield elements of small-plot trial reached values above the average. The variety "Libra" achieved the highest theoretical yield, with 3,04 t?ha-1. The average real yield of oil-flax achieved 2,24 t?ha-1 and the fiber-flax achieved the yield of 1,47 t?ha-1, which is typical for fiber-flax, regarding to the main production of fibre.

The comparison of spring wheat yield ability
KŘIVAN, Václav
This diploma thesis Comparison of yield capacity of spring wheat varieties deals with small-scale experiments of three varieties (Astrid, Epos, Tercie) in two vegetation periods. Repetition variations were established in 2015 and 2016 on the school grounds of the Agricultural Faculty of the University of South Bohemia in České Budějovice. During two growing seasons the production of yield elements (the number of plants and the number of fertile crops - ears) was monitored for all varieties and after harvest other yield elements were evaluated the number of grains in the ear and weight of a thousand grains. Actual revenue was determined. Grain analysis determined the bulk density as a quality indicator. In the results and discussion the individual yield elements are described and statistically evaluated. The number of plants was better in 2015 regarding soil density characteristics. The number of fertile offsprings was the highest in the case of Astrid variety in the first production year (642). The number of grains in the ear was very variable for all observed varieties, both production years 2015 and 2016 (from 15 grains in the ear to 68 grains in the ear). Total actual yield was higher in 2015 than in 2016 (by 1.1 t.ha-1). Each spring wheat is characterized by its shorter growing season, during which it must optimally produce the highest yield possible and therefore needs adequate responsible care.

Maize fertilizing in terms of selected agricultural company
HOVORKA, Jaroslav
My diploma thesis was focused on the corn nutrition in practical conditions of the agricultural company. The evaluation was made with the help of an experiment, which was made at an altitude of 508 metres, the experimental land belongs to the agricultural company Jasanka s.r.o. The experiment is based on the nutrition of corn with different fertilization doses. Various parameters characterizing plant development were observed during the vegetation season. The final results of this experiment showed the overall differences between the fertilized variants. For all the evaluated indicators, a decreasing tendency with a decreasing amount of nitrogen was confirmed. It is clear that all parameters of the best results were obtained for fertilizer variant 1 (58.5 kg N*ha-1). Similarly, for all parameters, the gradual decrease of values decreasing the fertilizer dose is evident.

The quality of wheat grain
VOKATÁ, Lucie
The main objective thesis was consider resistence of grow grain as elementary qualitative parameter food wheat by selection variety winter wheat. The test was create in vegetational period of years 2014/2015 on the plot of Faculty of Agriculture, University of South Bohemia in České Budějovice. In total was for test select 9 variety winter wheat. All variety had show high value number fall, high resistence against grow grain, which ranged 376 to 512 s. In evaluation observe variety suitability in terms of baking, we can say elite (E) inbreads reached the highest average number values fall (479 s). Quality (A) varietes showed value (453 s) and bread (B) varieties reached the lowest value (435 s). The partial objective was evaluation and other indicators (Zeleny test, The content of N-substances and density). Value of Zeleny test ranged 35 to 53 ml., from it averaged of all varietes 49,4 ml. The content of N-substances varied for each variety in 14,23 % - 16,52 %. Most of the studied varieties meet the standard set limit density (760 g/l-1). Ranged from 747 to 819 g/l-1. During the vegetation was also evaluated the health status of vegetation and there has been a determination of ears per square meter. After harvesting, they were also evaluated as further yield elements (number of grains per spike and HTZ). The experiment was evaluated by a high level of quality indicators, where individual varieties also showed high rebenues. This may be primarily affected by higher than average temperatures during the period of years 2014/2015, agrotechnics, but but also the level of nutrition and fertilization of crops.

The Minimalization of the soil tillage in the higher spheres
DOKULIL, Jan
The aim of the work was to monitor the yield elements and economics at indulgence of the winter barley and economics of the winter rape with usage of conservative technologies (shallow soil loosening, deeper soil loosening without reversion of the soil {--} only by the rape) in comparison with the conventional soil tillage (tillage). The yield elements by the winter barley were different in both years 2006 and 2007. In 2006 it was for the benefit of the tillage and in 2007 for the benefit of the shallow soil loosening. The number of growths was demonstrably higher at conventional soil tillage in spring and in autumn. The grain yield and the costs of herbicidal protection were observed. The highest yield at the winter rape was achieved by deeper soil loosening. The second place option was a variant of a tillage and the worst yield was found out in the shallow soil loosening. The final costs of the foundation of vegetation and herbicidal protection were lowest at the minimal soil tillage in all the options.
