The work is focused on the valuation of the impact of relief on the difference values of the chemical parameters of Eutric Cambisols, and to specifying correlation between observed properties of soils. The soils samples were collected in the autumn 2011 in the central part of Slovakia, on the neovulcanites of Kremnické vrchy Mts. We determined soil pH, the total content of organic carbon, the content of labile carbon, the content of potentially mineralizable nitrogen, the content of inorganic form of nitrogen, the sum of basic cations, the cation exchange capacity, hydrolytic acidity and base saturation. The values of soil pH in the monitored soil type were in the range from 6.3 to 7.2, the content of humus in the range 1,51 to 6.76%, the ratio of labile forms of carbon and nitrogen in the range from 15.53 to 80.92. When we observed the content of nitrate nitrogen and ammonium nitrogen in soil samples we found out that the content of nitrate nitrogen was 1.5 times (54.5 %) bigger on the slope and 1.1 times (10.5 %) bigger on the plain then the content of ammonium nitrogen.In statistical assessment of the variability of soil chemical parameters regard to selected types of relief (plain, slope) we found out a significant difference between the content of organic carbon (p = 0.021) and also the content of labile forms of carbon and nitrogen. The values of chemical parameters of soil were not affected only by shapes of relief, but also by higher level of groundwater. Positive relationship was found between the content of organic carbon and labile form of nitrogen in the soil samples (r = 0.747; p < 0.01). We also found a positive correlation between the content of labile forms of carbon and nitrogen (r = 0.600; p < 0.05).

The aim of this study was to assess the diversity characteristics based on probability of gene origin in Slovak Spotted breed. The animals were divided into 3 groups by breed types: group S0 where the ration of the other then Slovak Spotted breed was ˂ 12.5%; group S1 =12.5 - 25%; group S2 = 25-50%. The reference population of these groups consisted of 17355; 6251 and 12683 individuals, respectively. The pedigree information was available from the Breeding Services of the Slovak Republic, s. e. Total number of founders (f) ranged from 10484 for the S1 to 20402 for the S2, the effective number of founders (fe) ranged from 265 for the S0 to 507 for the S2, the effective number of ancestors (fa) ranged from 69 for the S0 to 112 for the S2 and founder’s genome equivalent (fg) ranged from 41.71 for the S0 to 70.75 for the S2. The most important ancestor EGE 003 originating from Slovakia explained 5.30 % of genetic diversity in purebred Slovak Spotted population. The results derived from probabilities of gene origin indicate, that the genetic diversity within each group was still relatively large.

Fusarium head blight occurrence was evaluated in ecological (Ďulov Dvor) and conventional (Veľké Úľany) crop production in Slovakia. The study was realized at the end of flowering stage – BBCH 69 of winter wheat (Triticum aestivum) in 2011 and 2012 years. 100 heads per crop of winter wheat were evaluated for FHB symptoms in three replications at each locality. The occurrence and severity of FHB was the highest in Ďulov Dvor every year, which corresponds to relatively high FHB index – 5.95 % (2011) and 12 % (2012). The lower FHB index (4.59 %) was recorded in Veľké Úľany in 2011. There were any symptoms of FHB in Veľké Úľany in 2012. Higher value of FHB index in Ďulov Dvor confirmed that the highest incidence and severity of FHB was in ecological crop production. Analysis of variance confirmed statistical difference occurrence of FHB between localities. The amount of rainfall was the main factor which influenced the lowest occurrence of FHB in Veľké Úľany in each year. The low rainfall correlates with low FHB index in Veľké Úľany. Conversely, the high amount of rainfall was related with high value of FHB index in Ďulov Dvor. Our results demonstrate that Fusarium head blight severity depends mainly on weather conditions. However, in years with average or high levels of disease, cropping system affects disease severity. These results showed for high incidence and severity FHB in ecological crop production.

The aim of the study was to analyse the effect of Rhus coriaria L. on fatty acids composition in table eggs. In the experiment, there were used laying hens Hy-Line Brown at the age 20 weeks, experiment lasted 21 weeks. Two diets for two hen´s groups (control: C and experimental: E) were used in trial. In control group, hens were fed by commercial total feed mixture, in experimental group the feed mixture was supplemented by Rhus coriaria L. seeds (1 % in feed mixture). During the last week of experiment, eggs of group were collected and after adjustment were analysed for fatty acids. In experimental group of hens was found in egg´s yolk significantly (P<0.05) higher percentage of myristic, myristoleic and palmitic acid. The same effect of Rhus coriaria L. was found in palmitoleic acid (P<0.05). In major fatty acid in yolk, oleic acid was found a positive effect (P<0.05), lower percentage in yolk fat in experimental laying hens group with supplemented feed mixture. In eggs from experimental group was found a tendency (P>0.05) of a higher linoleic acid percentage. The same tendency (P>0.05) was found in γ-linoleic acid. In egg´s yolk from control group of hens were found higher percentage of α-linoleic acid (P<0.05). In arachidic and arachidonic acid, there were didn´t found a effect of Rhus coriaria L. seed supplementation in total feed mixture hen´s diet.
