Effect of cultivation technology on the production characteristics of pea (Pisum sativum)
VACEK, Ondřej
Pea is the most widespread legume in the Czech Republic, with use in both food and feed production. In recent years, the cultivation of crops with larger row spacing has been widely expanded. For this reason, this bachelor thesis focuses on the characteristics of sowing peas, the effect of row spacing and the possibility of reducing the amount of sowing. In the practical part, the thesis focuses on conducting a semi-operational experiment of a pea multiplication crop and evaluating its yield factors and the content of the obtained production. The results obtained show the influence of row spacing and sowing rate on pea yield, number of pods per plant and HTS value, the factor of number of seeds per pod was not affected. Since the experiment was carried out only in one year, it will be necessary to repeat the experiment to refine the results, given the close relationship of the parameters evaluated to the soil and ecological conditions of the particular year. In experiments by other authors, differences in results may also be due to cultivar variability.

Combined mocrobial treatmens in hydroponic cultivation of tomato and cucumber the effect on yield parameters and antioxidant contens in fruits
Pikorová, Markéta ; Albrechtová, Jana (advisor) ; Látr, Aleš (referee)
Some microorganisms are known to form mutualistic symbiosis with plant roots and by their impact they can improve some plant parameters. These symbiotic microorganisms, which are able to improve some plant parameters, include especially mycorrhizal fungi, plant growth promoting bacteria and some saprotrophic mycoparasitical fungi. Mechanisms of changes of these parameters, as influenced by symbiotic microorganisms, are known only in part and nowadays are being actively researched. Aims of this work were to find out if selected microbial treatments influence selected growth, physiological and yield parameters of plants and contents of selected substances in fruits. Within this work were made three pot greenhouse experiments (experiments 1, 2 and 3) and three pilot greenhouse experiments (experiments 4, 5 and 6), performed on tomato (Solanum lycopersicum) and cucumber (Cucumis sativus) plants. Plants were grown in hydroponics using a carrier of rockwool and they were watered by nutrient solution. As microbial treatments for plants in experiments have been used a mixture of arbuscular mycorrhizal fungi (AM), mixture of plant growth promoting bacteria (PGPB), saprotrophic mycoparasitical fungus Trichoderma harzianum (Th) and various mutual combinations of these treatments. There have been observed...

Evaluation of spring application of growth regulators and stimulators in winter rape crop stands from selected farm
HNILIČKA, Ladislav
The work is focused on spring application of plant growth regulators and the operating conditions of agricultural society Kosova Hora, as Preparations were applied during the growth phase stands 32-33 BBCH scale, with 2 types of varieties - a line of hybrid canola varieties. 3 preparations were evaluated (Galleko, Toprex, Caryx) and one untreated area for control of the comparison of products. During the vegetation period were gradually on individual plots monitored the main elements of the plant yield (number of plants, number of pods, HTS, the number of branches). After harvesting canola yield was determined at the experimental plot. Results showed a positive reaction to stand on the treated area CARYX product. Attainment and income (4, 53 t / ha) on the experimental plot was achieved on a plot of hybrid rape. Difference treated variants compared to the control side were 0, 28 t / ha. This result is not statistically provable. The results are largely influenced the course of weather throughout the growing season. For better statistical power experiment would be preferable to multi attempts.

Effect of year, cultivar and size of seed potatoes on yield and quality of table potato tubers
CHUCHEL, Jan
In this thesis, the effects of year, variety and size of seed tubers on yield and quality of potato tubers were evaluated. In the two years (2011 and 2012), four potato varieties (Velox, Marabel, Adéla and Laura) were used. Size of seed tubers for all varieties was split into three size fractions: A < 35 mm, B 35-60 mm and C > 60 mm. In both years of observation were monitored following parameters: total and marketable yield, average number of stems per plant, number of tubers per plant, number of tubers per stem, the average weight of tuber, proportion of tuber size in harvested tubers, content of dry matter and starch in tubers fresh matter. Year contributed most to the total variability in total and market tuber yield (51.2%. And 54.4%, respectively). Size of seed tubers showed the highest proportion in the total variability of number of stems per plant (94.7%). Declared cooking type in all evaluated varieties was kept. Table value was significantly affected only by variety.
