Sladovnická kvalita zrna ječmene po mimokořenové aplikaci pomocných látek a listových hnojiv
Heža, Jakub
This diploma thesis focuses on the malting quality of spring barley grain after extra-root application of excipients and selected fertilizers. The theoretical part of this thesis is devoted to the factors influencing the yield and quality of grain. The practical part was focused on the evaluation of the influence of selected auxiliary preparations and foliar fertilizers on the yield and malting quality of spring barley grain. The issue was further explored in the form of both a small-plot experiment conducted on the land of Agrospol Velká Bystřice and a pilot trial in the locality of Hnojice in 2021. The experiment included the following variants: Control variant, 1. Lister Mo, 2. TS Impuls, 3. Aucyt Start , 4. TS Sentinel. Lister Mo and TS Impuls were applied in the developmental column phase (BBCH 31) and Aucit Start and TS Sentinel at the beginning of flowering (BBCH 50).vThe conclusion part of the diploma thesis summarizes and evaluates the fulfillment of the aim of the thesis.

Účinek kombinace hnojení dusíkem a mikroelementy na výnos a kvalitu rajčat
Koriťák, Pavel
The aim of this thesis was the evaluation of the effect of foliar fertilization by microelements combined with nitrogen fertilization on the yield and quality of tomato (Solanum lycopersicum L.) The experiment was implemented as a container experiment and field experiment. There were 5 variants of the container experiment: B1 (150 g B/ha), B2 (300 g B/ha), B3 (150 + 150 g B/ha), Zn1 (300g Zn/ha) and Zn2 (150 + 150 g Zn/ha) - all with the same dose of calcium nitrate. The field experiment was designed in Nová Červená Voda in 3 variants: B1 (150 g B/ha), B2 (300 g B/ha) a B3 (150 + 150 g B/ha) – all with the same dose of NPK fertilizer. In the container experiment, the highest NDVI was measured in Zn1 variant. The NDVI showed a significant dependence on the average yield of fruit. The lowest nitrate content was seen in Zn1 variant. The highest yield of fruit was in Zn2 variant. In the field experiment, the highest yield of fruit was in variant B3. The results of the experiments showed positive effect of nitrogen application combined with the microelements on yield and quality of tomatoes.

Biofortifikace slunečnice roční (Helianthus annuus L.) selenem
Vágnerová, Lucie
The diploma thesis is focused on a small-plot year-long experiment, carried out in 2013. The experiment monitored reaction of sunflower's (Helianthus annuus L.) hybrid NK Brio to foliar fertilizing with selenium, applied in the form of sodium selenite (Na2SeO3) during growth stage R1, at rates 50, 100, 150 and 200 g Se.ha-1. Foliar application of selenium at rates 50 - 150 g.ha-1 caused stimulation of weight of a plant biomass and nutrient uptake (esp. N, Mg and Se). Rate of 200 g Se.ha-1 inhibited plants' growth. Sunflower achenes yields were not statistically significantly influenced by foliar application of Se (p0,05). The most significant effect of foliar application of Se was its content in sunflower achenes; the amount of Se increased significantly (p0,05) in a linear relationship (r = 0.9824) to the graded rates.
