Kvalita cukrovky při uplatnění intenzifikačních faktorů
Andrýsek, Lukáš
The aim of this bachelor thesis has been to draw up a literature review on The quality of sugar beet after applying intensifying factors. In the practical part, a small-parcel field experiment has been conducted with the aim to examine the effect of extraroot nutrition from a company Klofáč spol. s.r.o. on the quality and the yield of sugar beet. We have tested these foliate fertilisers: Insenol, Carbon Si, Fumag 6NK Ca, Sulfika SB C, Carbon Bor K. For all these fertilisers, a positive effect on the technological quality of sugar beet has been proven. There has been a decrease in the content of harmful alpha amino nitrogen, the values varied up to 20 mg per 100 g of sugar beet, and there has also been a decrease in the content of soluble ash. Maximal values amounted only to 0.34 %. There has been a significant increase in sugar content and ripeness of the sugar beet. The values of MB factor ranged from 11.1 to 14.3. The extra-root nutrition has contributed to a harvest of high quality feedstock for subsequent processing. Indisputably, the good weather conditions and quality basic agrotechnology have also contributed with their part to it.

Pěstování ostropestřce mariánského [Silybum marianum (L.) Gaertn.] z hlediska ekonomických aspektů
Buba, Lukáš
The first part of the Master’s thesis describes the history and the present of milk thistle growing in the Czech Republic. Furthermore, the paper describes the biological characteristics, the varieties, phytochemistry and the use of this crop. The thesis in detail deals with the cultivation technology requirements. The classification of milk thistle in sowing procedure, tillage, nutrition, treatment during the vegetation period, harvest and post-harvest treatment of this crop are described. The second part of the thesis describes the course of weather and the growing procedure for this crop in the company Netis, a.s. Dry matter, purity, TKW, bulk density, germinability, oiliness and representation of individual components of the silymarin complex were determined in milk thistle achene samples. The experimental data found during the “first” cultivation at Netis, a.s. were evaluated in terms of the economy of cultivation. The economy of cultivation was compared with that of the traditional grower Agrospol, a.d. Knínice. The economy of milk thistle cultivation at Netis, a.s. was compared with that of other crops grown there.

Inovace pěstebních technologií konopí
Černý, Petr
The theoretical part of diploma thesis briefly focuses on botanical characteristics of cannabis, legislation of cannabis cultivation in Czech republic, agrotechnics and harvest of hemp. The cultivation technologies used in production and harvest of cannabis for pharmaceutical purposes are described in more details. In the practical part was established an experiment with cannabis plants. This experiment was carried in laboratory at department of plant biology at Mendel university in Brno. The experiment was carried out in two variants of light spectrum (white LED lights emitting complete visible spectrum and combination of blue and red LED in ratio 1:1), which were dividen into three groups with different trim method. In plants were observed parameters of quantum yield of electron transport of photosystem II, chlorophyll fluorescence, yield of dried flowers and selected secondary metabolites. In each of lighting and trim variants have been recorded various results. As results shown, white LED lights emitting a full visible spectrum appear to be more effective than the blue and red spectrum in ratio of 1:1. Effect of trimming in this experiment was not statistically conclusive.

Pěstování a odrůdový sortiment fazole zahradní
Karásková, Petra
The bachelor thesis is focused on the identification and evaluation of growth and yield indicators for selected assortment of garden beans varieties (Phaseolus vulgaris L.). The varieties are ´Amethyst´, ´Blanche´, ´Dalmatin´, ´Maxidor´, ´Novores´, ´Sigma´, ´Aidagold´, ´Gama´, ´Maxidor´, ´Rocco´ and ´Satelit´. Evaluation was made on land of Mendel University in Brno, 2016. There were evaluated individual growth characteristics of each variety in the work. First of all, the volume of the bush together with effective yield, the number and weight of fruit from one bush. Next, single fruit was evaluated its weight, length, width and number of seeds in the fruit. The content of vitamin C was detected in laboratory. The occurence of diseases and pests on beans were also evaluated. Acquired results were noted into tables, statistically evaluated and photo documentation was taken.

Farming practices for efficient use of nitrogen and reduction of its losses: Certified methodology for practice
Klír, Jan ; Haberle, Jan ; Růžek, Pavel ; Šimon, Tomáš ; Svoboda, Pavel
The methodology describes the main risks of nitrogen losses and recommended practices for their reduction. Practically applicable methods for the evaluation of the nitrate leaching risk depending on the soil, crop, root range, croping system, irrigation and weather conditions are described in detail. Consequently, suitable soil treatments and fertilization are proposed to improve the utilization of the nitrogen and uniformity of the water soaking.

Příčiny nízkých výnosů obilovin v ekologickém systému pěstování
KOTAŠKA, Vladimír
The aim of this diploma thesis was to find out the causes of low returns on chosen cereals (oat, wheat, rye, and spelled) in ecological agriculture based on evaluating information on growing procedures obtained via the method of questionnaires. Gradually, 21 ecologically farming companies controlled by the Abcert AB a Biokont CZ, s.r.o. organizations were chosen. Based on the analysis of growing procedures, the most frequent mistakes made by farmers were identified. Companies with lower returns apply mainly an inappropriate structure of crops grown, a high representation of cereals, and they do not respect crop rotation principles. Especially in favourble conditions, some farms are run without livestock production. Leguminosae representation is low in most companies, intercrops are used very seldom. In case of straw plow, the C:N ratio is not maintained using manure. Mineral manure is not used at all, liming very seldom. Vegetation is usually not fertilized during vegetation period. Cereal weed regulation is carried out, but not sufficiently. Using farm seed is quite frequent, which increases the growth of weed. Comparing returns on cereal among better and worse companies, it is obvious that respecting given principles may increase return on seed in 1.0 to 1.9 t/ha.

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.
