Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(2), 383-393 | DOI: 10.11118/actaun201967020383 
The subject of this article is a comparison of results of soil texture analysis of loamy and sandy-loam soils for soil erodibilty calculation using the Casagrande areometric method and results obtained by the laser diffraction method. A comparison was made of 27 samples taken from the Větřkovice locality, and 18 samples taken from the Hustopeče locality. On the basis of laboratory analysis of the soil samples, curves of grain composition were plotted, and the soils were divided into grain-size groups according to the ratio of individual fractions. For comparison of the results, the soils' regression dependence, with linear, exponential, quadratic and...

Heat milk stability (thermostability, TES) is important technological feature which can contribute to create higher added value in the dairy industry. The aim of this paper was to evaluate the seasonal dynamics and relationships of TES to other milk qality indicators in the results of an exceptionally large data set of bulk samples without technological compositional modification and acidity adjustment, just with native raw cow milk. There were carried out 2,634 of TES measurements including other milk indicators during 3 years under controlled farm conditions. Results were processed by polyfactorial linear model of variance analysis and linear and...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(2), 407-414 | DOI: 10.11118/actaun201967020407
The aim was to assess the internal and external quality of consumer eggs of egg-laying hens of two selected genotypes depending on their age. All of these hens were kept in enriched cages. There were compared eggs from Hy-Line Brown and ISA Brown hens at the age from 36 to 64 weeks. In total, 3840 eggs from 300 hens were evaluated. Quality of eggs was determined by their technological value. Statistically significant interactions (P = 0.001) between age and genotype were found in all evaluated parameters except for the yolk colour (P = 0.044), whereas there was not found interaction (P = 0.072) between age and genotype in eggshell strength. The significant...

The aim of the study was to investigate the risk factors for formation of hock lesions in dairy cattle farms with different housing system. The study included 508 Black-and-white Holstein-type cows from 14 dairy farms in different regions of Bulgaria. On cows a hock lesion assessment (scale 1 to 3) and body condition scoring (scale 1 to 5) were made. From the total number of cows, 231 cows (45.5 %) with score of 2 and 3 were reported, which clinical manifestation was from loss of hairs on the hock joint surface to swellings and wounds. A statistically significant effect of lactation period, body condition scores (BCS) and housing system on the hock...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(2), 463-470 | DOI: 10.11118/actaun201967020463
The most commonly used phytohormone to reduce the impact of drought is 24-epibrassinolide (EBR). In this study, EBR was applied over two years on young rootstocks of peach (B-VA-1) and myrobalan (Vanovice myrobalan) seedlings. Young rootstocks were treated by EBR at different concentrations, IAA and a mixture of EBR with IAA. The best results in seedling height of Vanovice myrobalan in both years had the treatment of 0.05% IAA, 549.69 mm (2016) and 553.77 mm (2017). On the other hand, on the crown root thickness was affected the most in 2016 by treatment of EBR 0.06 ppm (5.5 mm) and in 2017 by EBR 0.01 ppm (7.5mm). At B-VA-1 rootstock, the highest...

The idea of the political budget cycle impact on the public expenditure volume and structure raises discussion related mainly to the national government level. Political decision-making at the sub-national government level emulates certain common tendencies. In the election time, the political incumbent might seek for re-election. In aim to increase its own chances, it might manipulate the budget (or fiscal) policy and makes changes in the field of expenditure categories. In this paper, the existence of political expenditure cycle at the municipal level of government in Slovakia is investigated. The dynamic panel data model using the Generalized Method...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(2), 565-581 | DOI: 10.11118/actaun201967020565
After the fall of communism, the first non-governmental organizations (NGOs) were established in Slovakia in the 1990's. Since then, our NGOs have played an important role in promoting business ethics even though it was originally not part of their primary mission. Given that, we held semi-structured interviews with the leaders of nine prominent Slovak NGOs to identify the perceived causes of unethical practices occurring in the Slovak business environment. The results of this qualitative research suggest that our respondents connect the causes of unethical actions in business mainly with the macro-level of society, that is with the way the State with...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2019, 67(2), 597-607 | DOI: 10.11118/actaun201967020597
The labour market is differentiated by age and the individual's position in it is determined by age. Effective use of all workers' potential should therefore be a key human resource management strategy for all businesses regardless of the sector. One of the measures is taking into consideration the workers' age in agribusiness, i. e. applying age management. The aim of the paper is to evaluate the application of age management and to identify and evaluate its benefits for farming enterprises. The data was obtained by quantitative research at selected agribusinesses in the Czech Republic (n = 259). The research has shown that 25.1 % of the respondents...
