Analysis of production abilities of soya bean in selected agricultural company
ŠINDELÁŘ, Jan
This thesis presents the results of one year field experiment in the area of České Budějovice. The aim of thesis was to analyze the production abilities of selected varieties of soybean. A field experiment, with three soybean varieties, was performed in 2019 on a farm in Haklovy Dvory (leased by an agricultural company ZD Krásná Hora nad Vltavou, a.s.). The aim was to evaluate the real production capacity of soybean (Glycine max (L.) Merrill), in the conditions of the company. These varieties were selected - Abelina, Lissabon and Merlin. Except to yield, were also observed yield elements such as the number of plants per square meter, the number of pods per plant, the number of seeds in a pod and the weigth of thousand of seeds. Further, the total length of the plants, the number of primary branches, the height of the first pod, the content of fats and nitrogenous substances in the seed, and the amount of organic matter left after harvesting the seeds. For all tested varieties, a yield of over 2 tons per hectare was achieved, the Merlin variety even produced 2.7 tons of seeds per hectare. All tested varietis exceeded the profitability limit by yield, generally stated at 2 tons of yield per hectare. And they can all be considered acceptable for cultivation in the conditions locality České Budějovice. A considerable amout of organic matter from post harvest residues was added to the soil, in the case of the Abelina variety it was over 7 tons of matter per hectare.

Evaluation of seed yield and yield components in selected soya (\kur{Glycine max} (L.) Merrill.) cultivars in region with less favourable conditions
VŠETEČKA, Petr
The aim of this master thesis was the finding out of potential of growing the soybeans in the area with not so suitable growing conditions. The next aim was to perform the experiment with application of leaf fertilizer EGT Fulhum which increases root system volume. In the years 2016 and 2017 was in the altitude 395 m established the field experiment with the variety Amandine and since the year 2017 was also joint the experiment with the very early variety Abeline. Within these cultivars of soybean were evaluated these parameters: Seed yield, the 1000 seed weight, seed oiliness, plant height, number of pods on one plant, number of the early branches and weight of roots. The seed yield was very variable from the point of view of the year. The yield in the year 2016 was above-average, the control variant reached the yield 2,93 tons per hectare and variant treated by Fulhum 2, 78 tons per hectare. One of the studied parameter was the nitrogen content and based on the results of this parameter was noticeable reduction of nitrogen content of the treated variant in the comparison with control variant. In the further year were two compared two varieties - Amandine and Abeline. Within the both varieties were involved to the experiment the control variant and the variant treated by plant auxiliary substance. In the year 2017 was confirmed the influence of the crop area establishment on the yield quality parameters. The progress of weather confirmed the high requirements of soybean on the good rainfall conditions. Seed yield of the variety Amandine was 1,07 tons per hectare in the case of the treated variant, by control variant it was 0,88 tons per hectare. The difference of the seed yield between both variants of the variety Abeline was very little, it was 0,90 tons per hectare by the treated variant and 0,93 tons per hectare by the control variant. The application of the plant auxiliary substance didn't cause, on average, the improvement of the studied parameters so the using of this substance, for the improvement of these parameters almost doesn't make any sense.

Evaluation of winter oilseed rape yield of Pioneer company cultivars
DOSTÁL, Petr
This bachelor thesis deals with winter oilseed rape. The focus is placed on history, importance of cultivation, characteristics, yield creation and influencing factors. Attention is given to technology of winter oilseed rape cultivation, to selected oilseed hybrids of Pioneer company and to economy as well. The main chapter consists of the harvests results in the Czech Republic from 2014 until 2018. Another chapter is the response to the use of growth regulators in both semi-dwarf and normal straw hybrids. From the results of the thesis it was found out that the seed yields of semi-dwarf rape are comparable to those of normal straw hybrids. However, it strongly depends on the technology of cultivation and the climatic conditions of the given year and habitat as well.

Evaluation of tillage effect on seed yield of winter oilseed rape
TOMÁŠEK, Václav
This thesis was elaborated as a literary overview dealing with the issue of the tillage effect on seed yield of winter rape. First of all, thesis describes the development and importance of winter rape cultivation, its use in individual sectors (food, feed, oleochemistry and energy use). Next it describes the morphological structure of rape, its biological characteristics and some of its varieties. The second part of the thesis deals with the tillage effect on seed yield, development and character of winter rape root system. This part is focused on the classical tillage system that uses plowing and the minimum tillage system including for example conservation tillage, no-tillage and strip-tillage.
