Structural and concepcional changes related to the University of debrecen and its sport organizations between the period 2000–2013
133-139Views:242The strategic and conceptional approach to sport has brought substantial changes in the sporting life of University of Debrecen during the period between 2005–2013. The restructualisation process aiming at the development of university sport as well as the measures related to creating a more transparent financing system demonstrates elements of improvement in comparison to the period prior to the Bologna process. The Sport Concept of the university operates the different areas of sport within a transparent, planed and complex structural framework in accordance with the principles outlined in both the National Sports Strategy (2007) and the legal regulations specified by the Sports Law and its modification (2004, 2011). The conceptional changes of sport at the University of Debrecen followed the main objectives and guidelines of the European Commission that lays a great emphasis on issues such as the integration of athletes into higher education allowing maintenance of parallel educational and athletic carriers for athletes.

Coherence and connection between the good pond culture practice and the environment conscious management
60-73Views:76According to the data indicating the decline and restructuring during the past decade, as well as the trend in the European Union member states, it can be expected that the role of traditional agriculture and fish production in direct rural employment decrease further. This also values those strategic directions for restructuring that will lead fishculture from quantity driven to quality production along with sustainable development (i.e. environmental conscious production) and multifunctional farming. This way the economic and social tensions caused by the concentration of the production and labour output can be mitigated.
It is laid in the 1257/1999 Act on rural Development that farmers that enrol the agri-environmental scheme should follow the “Good Agricultural Practice” on the whole managed area. In case of agri-environmental schemes this is a precondition for which no grants are given.
The adaptation of “Good Agricultural Practice” in fishproduction,where it is called: “Good Pond Culture Practice” is considered important on the basis of the above mentioned. This programme is undertaken in co-operation with the Research Institute for Aquaculture, Fisheries and Irrigation, University of Debrecen, Faculty of Agricultural Economics and Rural Development and the Association of Hungarian Fish Farmers and Product Council.
The European Commission proposed the formulation of the European Fisheries and Aquaculture Fund (EFAF) for the period 2007-20013, which will replace the Financial Instruments for Fisheries Guidance (FIFG), but it also consists of several new elements and will be working differently, too. According to the proposal the budget for the Fund will be nearly 5 billion EUR (4963 million EUR). The development level of aquaculture and fisheries and the social and economic significance in the given member state will be considered when distributing the Fund between the Member States.
According to the plan the Fund is organised along five priority axes, of which the most important for the Hungarian fisheries sector is No. II: Aquaculture and the processing and marketing of aquaculture and fisheries products. The main measure areas are the followings:
1. investment support for aquaculture;
2. support for aquatic-environmental schemes;
3. environmental- and animal health issues;
4. investments in processing and marketing
In case of accessing support under measure area No. 2 farms are obliged to meet the requirements of the scheme beyond the “good management practice” for 5 years, which is to be supervised by the approved body of the Member State. For this reason our work is considered to be substantial.
Approval of the application of “Good Pond Culture Practice” is based on two elements: first the prevailing environmental and nature conservation regulations, as well as the list of controllable conditions in the new agri-environmental agreements are to be met. “Good Pond Culture Practice” are to be conducted on the whole farm area. Its main elements are:
- nutrition management,
- feeding,
- pond maintenance,
- stocking,
- harvesting,
- animal welfare (storage and over-wintering). -
Challenges and limtations of site specific crop production applications of wheat and maize
101-104Views:129The development and implementation of precision agriculture or site-specific farming has been made possible by combining the Global Positioning System (GPS) and the Geographic Information Systems (GIS). Site specific agronomic applications are of high importance concerning the efficiency of management in crop production as well as the protection and maintenance of environment and nature. Precision crop production management techniques were applied at four locations to evaluate their impact on small plot units sown by wheat (Triticum aestivum L.) and maize (Zea mays L.) in a Hungarian national case study. The results obtained suggest the applicability of the site specific management techniques, however the crops studied responded in a different way concerning the impact of applications. Maize had a stronger response regarding grain yield and weed canopy. Wheat was responding better than maize concerning plant density and protein content performance.

The phosphate state and biochemical mobilization of phosphorus compounds in arboreal plants’ soils
95-98Views:79Some indices of the phosphoric fractions of primery degraded soils, which are formed separate areas of technogenic landscapes, on a spoil-bank of iron-ore mine in the near of Kryvyi Rig, under act of lignosa, which are used for biological recultivation of degraded soils are investigated. Maintenance of mineral phosphates and features of organic phosphorus accumulation are set in soil under arboreal planting. Nutrient supply of plants is enhanced by mobile phosphates and their dynamics during vegetation period. Activity of alkaline and acid phosphatase enzymes are concerned also. On the basis of the soil enzymes activity information it is stated, that under the 35-years-old plantage of Robinia pseudoacacia L. the biochemical mineralization of organic phosphorus compounds passes considerably more actively than under Pinus pallasiana D.Don.

Analysis of the genetic origin of European hare (Lepus europaeus) (technical literature review)
49-54Views:158Fossil datas showed that the lagomorphs appeared in Asia during the later Eocene and leporids separated from ochotonids during the Oligocen or Upper Eocene. During the Pleistocene, climatic changes induced major shifts in species distributions, forcing them to refugia.
In Europe, the continuous oscillations led to the production of greater subspecific and specific diversity in the southern peninsulas (Iberia, Italy, Balkan) which were the main refugial areas for other species as well. Evolution, phylogeny and population genetics of the Lagomorpha species are still poorly known and the taxonomic distinction is still unclear for some species. Conservation genetics is the discipline which use genetic techniques and analysis methods to preserve species and dynamics. Usually it is working together with population genetics what role is to investigate the origin, the maintenance, the organization and the causes of genetic variation between natural populations. In the present study I reviewed the results of origin and phylogenetic studies of Brown hare populations from the last decades. -
Hungary’s correspondence with the EU regulations regarding liquid bio fuels
119-128Views:76During the recent years researchers from different countries have found that our environment is at risk. It has been recognised by the leaders of the member countries and they have made decisions together concerning environmental protection in several agreements, contracts. Unfortunately, these decisions have been weakened and adumbrated on numerous occasions by certain interests.
However, the energetic exploitation of the biomass has been supported by the economic and social changes of the previous years, more specifically, that of the bio fuels. The significant increase in the price of the traditional energy sources, the import dependency of the countries, the foreseeable exhaustion of the resources, the changes occurred due to joining the EU are all such problems that facilitates the application of bio fuels, as a good solution.
Our country decided to modify the then existed bio fuel component rate of 2% to 5.75% which has to be achieved by 2010. Since then, in March 2007 it has been expanded to 10% until 2020 (concerning energy content). This decision was taken knowing that this year (2006) the bio fuel rate has been 0.5%. However, the rate of 2% has not been achieved even in the EU. One can understand that the implementation cannot be fulfilled without significant political decisions and support. The main reason for this is that the price of bio fuels is not competitive with the present fossil-origin energy prices in Hungary. So in 2007 several regulations were modified. The most important one is perhaps the regulation of the revenue tax, which caused the successful tax-differentiation concerning bio fuels in more member states between 2007 and 2008. Its essence is that the revenue tax is not decreased, but if the fuel does not contain a bio fuel component of 4.4 bulking percentage per litre, „punishment” tax has to be paid. Moreover, on behalf of the implementation, regulations concerning bio fuels and bio fuel components are improving
At present the production and the application of bio fuels without any support are not economical yet. That is why it is important to emphasize the support policy of our country. After joining the Union, the new members can receive some shares from the direct disbursements, but only a tan increasing rate, we can achieve the 100% in 2013, though there is an opportunity for national contribution. Energy plants produced in agriculture receive separate supplementary support which is an advantageous opportunity for the farmers of the sector. Bio fuels cannot only be supported through agriculture, of course, but by research development, investment etc.
All in all, it can be concluded that Hungary seeks to fulfil the EU responsibilities taken and by this, to contribute to the maintenance of the sustainable progress, decrease of environmental pollution and the import dependency of energy sources. -
Vegetable production based on waste heat in closed greenhouses considering economic usage and competitiveness of the European Union
41-44Views:117The study investigates two professional fields; the questions of vegetable production in greenhouses, the necessary steam supply and heat regulations. The actuality of this investigation is provided by the planning of a combined cycle power plant of 2400 MW in Hungary. According to the plans the steam developing by generating electricity in the power plant can be used to intensify the vegetable production. In my current study I present the experiences and results gathered as member of the research and development team led by Mr. Dr. Sinórós-Szabó.

Soil Fertility Management in Westsik’s Crop Rotation Experiment
34-39Views:97The crop rotation experiment, established by Vilmos Westsik in 1929, is the best known and most remarkable example of continuous production in Hungary. It is still used to study the effects of organic manure treatment, develop models and predict the likely effects of different cropping systems on soil properties and crop yields. Westsik’s crop rotation experiment provides data of immediate value to farmers concerning the applications of fertilisers, green, straw and farmyard manure. The experiment also provides a resource of yield, plant and soil data sets for scientific research into the soil and plant processes which control soil fertility, and into the sustainability of production without environmental deterioration. The maintenance of Westsik’s crop rotation experiment can be used to illustrate the value of long-term field experiments.

The effect of different genotype cattle grazing on the nutrient content of saline grasslands vegetation
46-50Views:190Maintaining saline grasslands in good condition, preserving their yield and diversity is important not only for the purpose of nature conservation, but also for farming. Therefore, the primary purpose of our study is to analyse the effect of pasture use of the smaller weight extensive and the larger weight intensive beef cattle on the grassland vegetation and nutrient content. In this way, we can answer the question whether grazing for nature conservation can be achieved with more profitable, more economical and more intense varieties.
The tests were carried out in May 2016 and May 2017, in the Hortobágy National Park (Pap-ere and Zám puszta), where a total of 16 sample areas were analysed. These areas are grazed with extensive beef cattle (Hungarian grey) and mixed genotype of intensive cattle. The associations were selected along a moisture gradient, such as wet salt marsh (Bolboschoenetum maritimi) and drier saline meadow (Beckmannion eruciformis). All the vegetative material collected both years in May was analysed for the following parameters: dry matter, crude protein, crude fibre and life-sustaining net energy content. We compared the effects of medium grazing (0.46 livestock/ha) and abandonment on vegetation and nutrient content.
We examined the effect of (i) grazing, (ii) different grasslands (salt marsh, saline meadow) and (iii) grazing of different cattle breeds (Hungarian grey, intensive beef) on the nutrient content of the vegetation of grasslands Based on our results, it was found that grazing had an impact on crude protein and life-sustaining net energy content. The highest crude protein content (12.75 m/m%) was obtained in the year 2017 in the area where higher density had been grazed for two years. For the lifesustaining net energy, the highest value (5.05 MJ/kg d.m.) was also obtained in 2017 and the lowest in 2016. Furthermore, it was found that there was no significant difference between the effect of the two cattle breeds on the parameters examined. Significant effects were observed only in the case of life-sustaining net energy: in the area of intensive beef cattle we received a higher value (5.15 MJ/kg body weight) than in the area with extensive beef cattle (4.96 MJ/kg body weight).
Our results have also shown that cattle grazing is of the utmost importance for the maintenance of both wet and mesophilous habitats. Based on our three-year study, we can say that grazing by both extensive and intensive cattle breeds is suitable for the management of saline habitats.

Statistical comparison of coverage data of disturbed habitats in the Hajdúság
171-178Views:77Between 2002 and 2006 we made the coenological survey of five disturbed habitats marked as grasslands. With our coenological examinations and the statistical analyses we wanted to make the detailed botanical survey of the given five habitats in order to verify that the maintenance of habitats amongst agricultural lands – and considered as less valuable – is of high importance and necessary from an environmental point of view, since these habitats are often living and feeding areas of many rare and/or protected plant- and animal species.
As a result of the statistical analyses we have pointed out that number of species in case of all the five habitats extreme fluctuation characterizes the statistical universe. As regards the
average of the coverage it is the highest in case of the third habitat (degraded Puccinellia grassland), and the coefficient of variation shows homogenity as well. In examining the Shannon-value the average is the highest in case of the second habitat (Alopecurus meadow), and the statistical dispersion is the smallest. The coefficient of variation shows medium variability. The median of evenness is the lower in case of the third habitat (degraded
Puccinellia meadow) and the statistical is the highest here as well.
We have done the Hierarchical and the K-Means Cluster Analyses for the 21 plant associations of the five habitats. Both cluster analyses put the same associations into the same cluster, so
one can state that the associations in each cluster are different from the associations of the other ones according to the coverage data of the plant families. -
External governance and economic patriotism in European policies
35-39Views:105The concept of external governance tries to define the expanding scope of EU rules beyond EU borders. This article presents the theoretical foundations of the concept, differentiating the various institutional modes according to which external governance may take place. Due to the financial and economic crisis the European Union is forced to strengthen its competitiveness opposite to cohesion. In the second part of the study I present the five mechanisms by which the European Union may foster its position in the global competition. The five mechanisms are as follows: extension of the political space of the EU, expansion of the regulation mechanisms of the EU, active coaching of international organisations, territorial extension of the EU’s influence, division of the costs of globalization. After that I deal with the different forms of economic patriotism. Economic patriotism plays crucial role in maintaining the performance and strengthening the position of some preferred domestic industries, ‘national champions’. Tools of economic patriotism differ due to ideological affinities.

The effect of compost made of sheep manure on the first cut of a semi-natural grassland
25-29Views:197In an experiment, two types of compost were tested on natural grassland in order to improve the productivity of a natural sward on solonetz soil. Both composts were made of on-farm produced sheep manure, but the second one was enriched in phosphorus. These fertilizers/composts are officially authorized and can be applied in organic farming. Zero application and three rates of fertilizer were tested (10 t ha-1, 20 t ha-1, 30 t ha-1) on 30 m2 experimental plots wit four replications. Dry matter, crude protein and net energy content for maintenance were measured and determined and their yields per unit area were calculated. We found that all the treated plots produced significantly higher yield than the control ones, and in some cases the yields were almost three times higher. However, the optimal compost dose varied, depending on the examined parameter. Based on the evaluation of the experiment results along with rainfall data, it was concluded that, with higher precipitation, the positive effect of the compost application was bigger. The difference between the natural and enriched compost is remarkable, but it has to be mentioned that even the natural compost showed good results; therefore, it is also effective in improving the fertility of grassland.

Comparative examination of a mineral fertiliser and a bacterial fertilizer on humic sandy soil
111-116Views:83In our pot experiment, the impact of a bacterial fertilizer, Bactofil® A10 and a mineral fertilizer Ca(NO3)2 applied in different rates was studied on some soil chemical and microbiological characteristics of a humic sandy soil (Pallag). Perennial rye-grass (Lolium perenne L.) was used as a test-plant. Samples were collected four and eight weeks after sowing in each year. The experiment was set up in 2007-2009 in the greenhouse of
the UD CASE Department of Agrochemistry and Soil Science. The available (AL-extractable) nutrient contents of soil, among the microbial parameters the total number of bacteria, the number of microscopic fungi, cellulose-decomposing and nitrifying bacteria, the sacharase and urease enzyme activity, as well as the soil respiration rate were measured.
Statistical analyses were made by means of the measurements deviation, LSD values at the P=0.05 level and correlation coefficients were calculated. Results of our experiment were summarised as follows:
− The readily available nutrient content of humic sandy soil increased as affected by the treatments, in case of the available (AL-extractable) phosphorus and potassium content the higher value was measured in high-dosage artificial fertilizer treatment.
− The treatments had also positive effect on several soil microbial parameters studied. The higher-dosage mineral fertilizer treatments had a beneficial effect on the total number of bacteria, cellulose-decomposing and nitrifying bacteria. No significant differences were obtained between the effect of treatment in case of the total-number of bacteria, the number of microscopic fungi and nitrifying bacteria.
− On the sacharase enzyme activity the artificial fertiliser treatments proved to be unambiguously stimulating, the urease activity significantly increased on the effect of the lower-dosage Ca(NO3)2 artificial fertilizer treatment.
− The soil respiration increased in all treatments in related to the amounts applied, significantly increased in the highest rate of Ca(NO3)2 fertilizer addition.
− Some medium and tight positive correlations were observed between the soil chemical and microbiological parameters studied in case of both nutrient sources.
Summarizing our results, it was established that the organic and all the mineral fertilizer treatments had beneficial effects on the major soil characteristics from the aspect of nutrient supply. In majority of the examined soil parameters (AL-extractable phosphorus- and potassium, total number of bacteria, number of cellulose-decomposing and nitrifying bacteria, activity of sacharase enzyme) the high rate of Ca(NO3)2 mineral fertilizer treatment proved to be more stimulating, but at the same time the high rate bacterium fertilizer resulted in significant increases in
the nitrate-N content, the AL-potassium content of soil, the total number of bacteria, the number of cellulose-decomposing and nitrifying bacteria and the urease enyme activity.
Our examinations showed that the mineral fertilizer treatments proved to be more stimulating on most of the soil parameters studied but according to our results, it was established that Bactofil is efficiently applicable in the maintenance of soil fertility and the combined application of
mineral fertilizer and bacterium fertilizer may be a favourable opportunity – also in aspect of the environmental protection – in maintaining soil fertility.
