The spring barley fertilization in terms of selected agricultural company
ŠINDELÁŘ, Jan
This thesis presents the results of malting barley's fertilization obtained on the basis of a field experiment in an agricultural company. The aim of the work was to determine how the rate of nutrients will affect yield and malting quality. Fertilizing was based on three different rations of LAV fertilizer given to plants in an advanced phase of their growth. The rations of nitrogen were set to 20, 40 and 60 kg per hectare. The positive effect of a late fertilization was observed for yield elements. There has been an increase of the number of grains in the ear and of the weight of a thousand grains. Some malting properties were also improved. It was especially the fraction of the front grain and in part germination. But the content of N-substances exceeded the limit in two of three variants.

Foliar fertilizers containing collagen hydrolyzate for nutrition of grapevine: applied methodology with certification
Horák, Jaroslav ; Raimanová, Ivana ; Kurešová, Gabriela ; Trčková, Marie
A comprehensive methodology describing the use of products made from collagen hydrolyzate for leaf nutrition of main field crops and vines grown in conditions of organic farming as well as within the conventional method of cultivation. Elaboration of the methodology was preceded by applied research to develop environmentally acceptable ingredient - collagen hydrolyzate, where undesirable sodium is replaced by biogenic, often scarce potassium. Another objective was to optimize content and a mutual ratio of trace elements from the perspective of requirements of particular crops or their groups. Within the methodology are stated all the information needed for qualified decision-making regarding to foliar application of newly developed products in organic and conventional mode of farming. Examples of practical use of both types of fertilizers are the result of their application in field trials and South Moravian vineyards with standard and biological growing system.

The influence of pratotechnical way of use on species composition and characteristics of selected permanent grasslands
HAŠKOVCOVÁ, Petra
The aim of this work is to assess the influence of mowing and grazing with different frequency and fertilization on species composition, fodder value and bimas production. The experiment was carried out at the village of Hrazany, district of Písek in 2017. The ecological conditions of grasslands, terms and intensity of use, biomass production, botanical composition and species diversity were monitored on these parcels. The data obtained was used to calculate the Hill's Diversity Index, calculate the pasture load, and calculate the yield in dry matter. Non-fertilized plots reach the lowest yields. Most grasses are located on the soil fertilized with urine. The smallest disturbance and shortcomings appear on the pasture with the finch pasture. The values were statistically processed.

Faktory ovlivňující množství silice izolované z různých taxonů rodu Mentha L. (máta)
Pražák, František
The aim of this thesis was gathering current literature data on factors (internal - the type, stage of development) and (external - soil and climatic conditions for cultivation) that most affect the oil content in the genus Mentha L. On the basis of the results obtained during laboratory analysis of quantitative content of essential oils in plants of the genus Mentha L. taxa planted on an experimental plot of garden-technical faculty in the refrigerator was a hypothesis based harvesting time, the impact of species and cultivars on the essential oil content is confirmed. Further, the predicted calculation that based on the current state of the essential nutri-ents in the soil experimental plot could be the addition of nitrogen fertilizer to increase the amount of green mass, and while maintaining the integrity of the plants, especially leaf area increase the total yield of oil from the cultivated taxa genus Mentha L. The direct impact of climatic conditions on essential oil content was not established due to the very dry summer with little rainfall and dependence on irrigation.

Výživa cukrovky při nedostatku hořčíku v půdě
Dostal, Tadeáš
The goal of this project was to compare the different compounds of magnesium and its influence on yield and volume of sugar beet. This project was realized by small plot experiment in Pusté Jakartice u Opavy. Sugar beet was fertilizated using four different experiment setups: 1. not fertilized, 2. DUMAG (ammonium nitrate + magnesium nitra-te), 3. DASAMAG (ammonium nitrate + ammonium sulphate with magnesite), 4. MAGNISUL (ammonium nitrate + ammonium sulphate with kieserite). Variety with fertilizer DASAMAG has the highest yield of sugar beet. The highest digestion of sugar beet has non-fertilizated variety and variety with fertilizer DUMAG.

Využití kapalného hnojiva DAM-390 k přihnojení kukuřice během vegetace
Lapčík, Vlastimil
The diploma thesis deals with the observation of the maize. The quantitative parameters of the maize, variety KWS 9361 fertilized by nitrogen liquid fertilizer DAM - 390 were observed and evaluated during one year field experiment. The base level of 156 kg N.ha-1 was applied in all variants before the start of experiment. Nitrogen fertilization was used separately or in combination with a weeder as well. Variants 3 - 6 were subsequently fertilized with extra amount of 39 kg N.ha-1 to the total level of 195 kg N.ha-1 and compared to variant 1, respectively with variant with usage of weeder without any extra fertilization (variant 2). The grain yield increased in all variants in comparison to variant 1. The highest numbers of collected data were found out in connection with variant 4. The yield ranged between 10.54 and 11.94 t.ha-1. The significant differences among the variants were proved after the determination of dry matter, N content during the growing period, thousand grain weight, and starch content of collected plants.

Vliv vápnění na druhovou skladbu a výnosy polopřirozeného travního porostu
Sláma, Miloš
Between 2014 and 2015 was monitored the influence of liming and N fertilization on dry matter yield, floristic composition, species diversity and quality semi-natural grassland at the experimental flat Kameničky. The experimental plots were arranged in four repetitions and divided into not limed and limed blocks. For the purposes used liming ground dolomitic limestone. Nitrogen in the form of urea was applied at doses N0, N50, N100. Species composition affected all indicators monitored permanent grassland, while also have an influence on yield formation. Nitrogen fertilization without other nutrients to the experimental flat Kameničky did not manifest into higher yields, higher species diversity and quality of the grassland. N fertilization increased portion of more valuable grasses at the expense of other herbal, but put down (P<0.05) representation intergeneric hybrid Festulolium pabulare. Liming had an impact of plant species which have been adapted to the acidic environment and also not increased yields. In species composition increased (P<0.05) representation Festuca rubra L., Agrostis spp. that have low requirements on nutrients and there were no (P<0.05) Alopecurus pratensis L. and Ranunculus repens L. Liming not caused higher diversity and not caused the quality of grassland.

Vliv agrotechniky na produkční charakteristiky a ekonomiku výroby silážní kukuřice
Bártů, Ondřej
The subject of this thesis was through a field experiment to compare the economics of different options silage maize. Comparisons were ways to stand establishment and variants of fertilization, the nitrogen dose was always the same. It analyzed the influence of fertilizer with the addition of sulfur on maize cultivation. When comparing the establishment of vegetation were evaluated influences on selected production characteristics of silage maize. It was evaluated price per sown hectare, more expensive option, seeding side dress treatment under the heel was implemented through agricultural services and cheaper alternative was seeding fertilizer under the heel of machines owned by the company. Fertilization formed the basis of all variants urea applied before seeding at 250 kg per hectare. In cases when fertilizer was applied directly to seed, it was also used urea. The rest to a total dose of 200 kg nitrogen per hectare was in both versions foundation used more fertilizers, which was urea, manure and aqueous solution of ammonium sulphate with urea (SAM). Even if fertilization effects were evaluated at selected production characteristics depending on the price.
