New Integrated Breeding Evaluation Method Used for German Warm-blooded Horses
3-6Views:222In Germany, the new integrated breeding value estimation is based on a multiple-trait animal model, considering simultaneously information from performance test of stallion on station, performance test of mares as well as competition results of sport horses. The objective of this study was to estimated the genetic parameters of the traits used in the integrated breeding evaluation including all German warmblood breeds. The analysed data consisted of 4527, 40670 and six million records for performance tests of stallions, mares and for competition results, respectively. Genetic parameters were estimated with a multivariate BLUP animal model. Heritabilities for traits obtained from stallions tested on station ranged from 0.33 (jumping under rider) to 0.51 (trot) and for the traits from mare performance test from 0.27 (walk) to 0.38 (trot). Genetic correlations between corresponding traits recorded on performance test of stallions and mares ranged from 0.87 (canter) to 0.98 (free jumping). Heritabilities of competition traits from horses (build up for sport) were estimated as 0.12 and 0.11 for dressage and jumping, respectively. The use of all traits for estimation of genetic values of horses is expected to reduce pre-selection and optimal combines all information resources based on the estimated genetic parameters.

The economic risk analysis in the case of agricultural enterprises
107-116Views:236The company’s activity, profitability and growth potential are influenced by risk and uncertainty derived from the economic environment. The principal thing that makes difference between risk and uncertainty is the capacity to be quantified, and then the risk can be measured, whereas uncertainty is not. Specific risk types of agricultural enterprises are on the one hand the economic risk and specific risk arising from the main agricultural activity. The economic risks include financial risk categories like market risk, liquidity risk, credit risk and operational risk. Macroeconomic risk manifest also a significant influence to the company and the importance of taking into account of this, importantly increased in recently years. In present paper, I quantified the total risk of company by using financial and operating leverage indicators. The company’s growth was characterized with internal growth rate and sustainable growth rate. The present research aims to explore risk and growth level of agricultural companies and grouping companies by different characteristics. In present analysis I have used cluster analysis. From the results I can summarize, that the agricultural enterprises growth is made by using internal financing resources and their financial leverage level is lower that operating leverage level.

The future of apple growing in the Northern Great Plain region
35-38Views:408We revealed and assessed those macroeconomic data which enabled us to identify the outstanding role of agriculture and within it that of fruit production. Based on this, it can be said that soil is the most important natural resource of Hungary. The appropriate combination of the additional resources required for production, labour and assets can provide a comparative advantage for the Northern Great Plain Region.
The Northern Great Plain Region is one of the most underdeveloped regions in Hungary, so its development is a political objective. When analysing the economic sectors in the region, the important role of agriculture is obvious and it is also clear that the industry and the tertiary sector can only have an alternative income generating role in the future also. Therefore, it is important that the regional development funds of Hungary and the European Union are directly or indirectly aimed at improving agricultural development and competitiveness. -
The Effect of Tillage Treatments on Soil Temperature at Planting and on Corn (Zea mays L.) Yield
40-44Views:518The effect of soil temperature was evaluated on the yield of the Occitan corn hybrid at a depth of 5 cm. We examined this effect on the time required from planting to emergence for three average durations: five, ten and fifteen days, all calculated from the day of planting. Winter plowing (27 cm), spring plowing (23 cm), disc-till (12 cm) treatments and 120 kg N per hectare fertilizer were applied. As a result of our analysis, we determined the post planting optimum soil temperatures for various time periods. The average soil temperature for a time period of 15 days post planting is the most usable for determining actual yields, followed by ten days, with five days proved to be the least usable (winter plow R2 = 0.86, spring plow R2 = 0.87, disc-till R2 = 0.64).

The role of Local wine administration bodies in creating social and cultural capital and in the preservation of local identity
181-191Views:165the target for the European Union to make Europe the most competitive and dynamic knowledge-based economy in the world. In this process, the education and training are of great importance for the member states. The restructuring of higher education, the modernization of the universities cannot be achieved without new financial resources. They should be ensured by increasing contribution of the private sector. However it is not enough to invest sufficient funds in the educational and training system, they must be expended efficiently. The free higher education itself does
not necessarily guarantee the equal access and maximal participation. The quality of higher education and equal opportunity can be improved, if the rising funds are expended on infrastructure development and creating an efficiently working student support system.
Quality, equal opportunity, efficiency – they are the most important views for the decision-makers in the higher education reform. In my paper, I would like to interpret definitions relating to higher education and in this way I attempt to evaluate the financing systems of the Hungarian higher education formed since the change of the regime, with special regards to the normative financial system combined with the payment of tuition fees. For classification, it is necessary to present the different basic financial models. Furthermore, on the basis of the above criteria, I try to make recommendations on how to improve the present financial model in order to achieve the Lisbon objectives.
The topic is important in our days, because tuition fees will be introduced in Hungary from 2008. The problem is very complex, although the analysts in most cases tend to approach the topic with prejudice, depending on their financial and political interests. My analysis may contribute to discernment in the tangle of the pros and cons. -
A partial botanical survey of a gamepreserve
27-30Views:475Hungary is internationally well known for its high level game management. An important part of game management is indoor game keeping. In Hungary more and more game preserves were founded all over the country. The role of these game preserves to retain forest stands outside of the closed area. According to the law, in the game-preserves the game bearing capacity is not the most important parameter, because in these areas the feeding is continuous. In practice it means that in game-preserves we find a much higher density of games than in nature. This causes a relative big loading of the area (of the herbaceous and arboreal), where the game-preserves are located. Our aim is to study the ecological and management issues of forest- and game resources. The scene of these work is a game-preserve related to the Nyírerdő Corporation (Nyíregyháza).
We have done a botanical survey (plant coverage, life-form spectrum) in the three previous units and in the control area (outside of the game-preserve) as well. Our results show the difference in case of the state of herbaceous plants between areas with higher and lower game density. -
Development of and Lessons from the Institution System of the Common Agricultural Policy in Slovenia
43-53Views:176The comprehensive agricultural policy of Slovenia during the setting-up of its agricultural institutional system for implementation of the Common Agricultural Policy has enabled the setting-up and design of the Paying Agency system to handle national and EU subsidies according to schedule. The country has acted on the advice of the European Union to use the introduction of SAPARD measures as a preparatory and experimental field for utilising subsidies after EU accession. Moreover, in addition to the importance of gaining practical experience in the field of implementation of rural development measures, Slovenia has recognised the necessity to become familiar with the application procedures for obtaining direct payments relevant for the largest group of beneficiaries, farmers. Accordingly, farmers have been practicing for 3 years how to fill in application forms, and have gained important experience before opening the most relevant resources. Also, the advisers supporting farmers to obtain subsidies have been trained during the last 3 years, in order to provide real assistance. EU agricultural subsidies are not divided among the Member States; there will be a strong competition not only with the new Member States, but also with the farmers of the more developed EU-15.
Slovenia has done its best in order to launch its farmers – due to the different development levels of the EU-25 Member States – into this very strong competition not like pupils, but at least like mature secondary school students. -
Gene resources for improvement of drought tolerance and yield quality in dry pea breeding
105-111Views:241The effectiveness of selection for improved drought tolerance and consumption quality in the progeny of crosses between pea cultivars with semi-leafless (afila) and normal leaves and different origins, respectively, were investigated. After single crosses, parent cultivars and F1, F2 and F3 generations were grown under non-irrigated conditions in the same trials. We created a colour scale from 1 to 9 to measure statistically the shade of seed colour. The tolerance of genotypes against high temperature was measured by the number of pods per plant. The 3:1 segregation
observed in the F2 generation of crosses between semi-leafless and conventional cultivars indicated that the semi-leafless character is determined by a recessive gene. In contrast, the ratios of conventional (Af) and semi-leafless (af) genotypes were 7:1 and 9:1 ratio in the progenies of crosses of Af × af. The genetic progress was effective for improving the seed quality in F3 generation from crosses Af x af where we found that multiple
dominant alleles controlled the orange colour of cotyledons and its high heritability (h2 A=0,63). Selection is more effective in producing the genotypes with high yield and normal leaves if the crosses were made between the western European cultivars such as semi-leafless Profi and Delta used as maternal cultivars and conventional Auralia cultivars. In this case, there were decreases in the consumption quality, such as seed size and shade of colour. The selection based on the seed weight of single plants for increasing drought tolerance seemed to be more effective in F4
strains with normal leaves originated from Czechoslovakian maternal cultivar Y228; however, the genetic progress in the improvement of seed size and colour quality was slow. -
Energy efficiency in Hungary and abroad
147-150Views:221Nowadays decentralized energy supply and the energy security are becoming more involved. We should increase the share of renewable in the energy mix, addition to improve the energy efficiency. Hungary is not an abundance of fossil resources it is particularly important in the materials and energy-saving technologies, waste recovery, increasing the share of environmental energy. Our country has outstanding opportunities many areas for example, solar energy, geothermal energy, so we need to devote more attention to renewables in the future.

Economic Assessment of Biodiesel Production for Hungarian Farmers
72-76Views:226Utilisation of oil of plant origin as a fuel is gaining acceptance in the European Union and elsewhere. Besides environmental protection, energy saving, and decreasing over-production of food. Additionally, the subsidisation of farmers and the development of rural sub-regions also contribute to its spread. This study specifically focuses on the direct effects biodiesel's raw materials and final products are now having on farmers, while reviewing and quantifying these effects. I have purposely restricted my analysis to these two elements of the biodiesel chain.
The biodiesel chain seems to be a great method for improving the economic and social position of participant farmers in many ways. Presently, the profitability of raw materials’ production looks to be the crucal point in the chain, and could be strengthened best with intensive, habitat-specific agrotechnic. It would only be possible to reach a favourable profit margin for farmers if yields reach unrealistic averages or if there is a significant hike of the 2000 producer’s price in the oil plant branch.
The main attraction of sunflower- and oilseed rape production lies in the stabilization of market conditions, which is not only gong to appear in oil plant branch but – thanks to the reduction of outputs – also in the cereal branches. Better economic safety for farmers may play a role at least on the same level as in plant production, which involves more risks than profit maximalization.
The reduction of the prime cost of biodiesel could be possible through the direct combustion of the whole oilseed plant or its residues or electricity production using them. Whereas energy demand for biodiesel production is low (appr. 5%) but it needs subsidization and the prices of natural gas and electrical energy presently look favourable in Hungary. Additionally harvesting and baling of the residues is technically problematic, which is why their use may seem to be reasonable just over the middle or long term. Another possible factor of cost reduction could be the centralization of some partial operations, which needs serious financial resources to reduce amortization cost per product, provided there be several biodiesel projects near each other during establishment. Creation and operation of a logistical system could also be a good method for improving the viability of the biodiesel chain, in order to optimize transport schedule and distances. However there are also some organizational difficulties in this case. -
Sustainable energy management – the importence of the renewable energy sources, their difficulties and chances
145-154Views:211The biggest question of the century standing before us is that if people will be able to direct the development to sustainable direction. One of the components of global problems threatening
us is the pressure that the energy management puts on the environment, which can be significantly lowered by utilizing renewable energy sources. The aim of my study is to draft the
model of a sustainable energy management, putting the renewable energy sources into it in a sensible way, regarding the possibilities of Hungary. -
Soil moisture sensors for sustainable water management in field crop production: A review of advances and application challenges
41-54Views:447Efficient water management is essential for sustainable production of field crops amid climate change, population growth, and water scarcity. Traditional irrigation practices often lead to water use inefficiency, which harms soil health and reduces yields. To address this, reviewing previous studies on soil moisture sensors provides important context and guidance. Literature from Scopus, Google Scholar, and WoS (2019–2025) on soil moisture sensors for sustainable water management in field crops was screened. Out of 244 retrieved publications, 79 met the inclusion criteria with a focus on sensor technologies, applications, advances, and challenges, analysed thematically for research gaps and insights. Based on the findings, soil moisture sensors boost water management, improve yields of field crops, and support sustainable agriculture. However, hindrances related to high costs, lack of awareness, technical complexity, calibration needs, energy challenges, data interpretation difficulties, and compatibility problems hinder effective soil moisture sensor results. Integrating soil moisture sensors with decision-support tools optimises water use and protects soil health to promote long-term productivity under climate variability. Future research should strategise on the development of low-cost, reliable soil moisture sensors with technology subsidies, training, policy support, durability, integration, and simple data to empower farmers to adopt precision water management.

Local strategical tasks in the Hungarian fruit production with respect to the global economic and climatic changes
39-34Views:344After identifying the problems, we have determined the local tasks which Hungarian fruit growing has to accomplish to remain competitive despite global market pressures and global climate change.
Fruit growing in the Great Plain is of determining importance in Hungary as 75% of fruit originates from the Great Plain. Therefore, the maintenance of the competitiveness of fruit growing on the Great Plain is an important economic interest which is a difficult task to resolve, because the global economic pressure against local resources and climate change affect the fruit growers sensitively.
In Hungarian fruit production, it is necessary to select/develop with great care the appropriate location, training system and methods of emergency technology which have to be harmonised. -
The dual function of soil: natural resources and production site
5-19Views:169First, we begin with a review of the global situation, followed by a description of that in Hungary itself. Next, we consider the conditions affecting soil utilization, and their relevant problems. Finally, we make a brief prediction of what can be expected in the coming two decades or so. For this latter reason, it is necessary to briefly illustrate the situation, processes and relationships.

Practical experiences in Moodle LMS
129-133Views:166We use Moodle at the University of Debrecen, Business- and Agricultural Department since January 2007. Moodle is an open source Learning Management System.
Learning Management System (or LMS) is a software package that enables the management and delivery of learning content and resources to students. Most LMS systems are web-based to facilitate "anytime, anywhere" access to learning content and administration. LMS tracks student progress in a course and indicates completions. At the least, learning management systems track individual student progress, record scores of quizzes and tests within an online learning program, and track course completions.
Moodle has more and more function at our Department in education. At present, we work to introduce Moodle in our Faculty. Therefore, we took lessons for the tutors about the usage of the Moodle. Our aim to develop such a learning system, which is an integral part of educational process. -
Correlations of the global, regional and local factors of the anthropogenic effects on the water reserves of the Earth’s crust
85-92Views:223The decrease in Earth's drinking water resources and the degradation of its quality has become a critical problem. Our planet's total water supply is estimated to be around 2 billion km3s. This is only 1% of Earth's own weight. Of this small amount only a tiny 3% is fresh water, of which 79% is forzen in glaciers and 1% is present as surface waters.The ratio of water stored in soil is around 20%. This is 0.2% of the total water supply. Our study aims to summarize the layered groundwater aquifer systems and its changes which are the results of anthropogenic effects in both global and hungarian respects and also for the region of Debrecen.In particular with regard to the geological and ecological level where irreversible
processes take place. All this is discussed in the context of cause and effect. Pointing out the dangers of excessive deep groundwater extraction and the contamination caused by toxic substances that are the byproducts of modern life. In addition we discuss the Water Directive of the European Union which gives a policy for community action concerning the goal to achive the status of „in good condition” for our waters till 2015.
