    In my study titled “Regional strategies serving competitiveness”, I examine the regional strategies whose development and implementation in practice play a determinant role in the medium- and long run economic and social development of the given region. The study primarily focuses on the infrastructural basic investments that are essential from the aspect of creating a knowledge-based information society. The study also deals with a stakeholder analysis used by investors in order to focus on the quality of state administration and institution system.

  • When and what quantity shall we buy? Optimal cereal – acquisition strategies

    For farm products, it is typical that goods appear in a certain period of time in gross; therefore, from the viewpoint of forestallers/users, it is an important question how much and when to buy and for growers how much and when to sell. Among the costs that have affects on income, we have to emphasize stockkeeping costs (i.e. cost of tied-up capital, ordering costs) and acquisition costs. The last one is very important, because we can
    notice great divergences in prices for cereals associated with the significant seasonal factors for a given year, so acquisition prices affect substantially the evolution of our costs.
    We can establish the strategies in two steps: setting up 2 models and interconnecting them. One means the strategies that differ from each other in ordering quantities and these comparative analyses. This model contains the analyses of seasonal effects and also the results that we apply in the model. The other one is a dynamical mathematical programming model which – by considering alternative investments – helps us to choose from the strategies in the previously mentioned model that one, which assures us maximum income. 

  • Agri-Environmental Issues in the National Sustainable Development Strategy of the Member States of the Enlarged EU

    In preparation for the World Summit on Sustainable Development (Johannesburg), almost all EU member-states and some accession countries presented their national strategies for sustainable development (NSSD) during the summer of 2002. Along with other countries, Hungary is only now setting up this important document. Everywhere during the last decade, as in the EU countries, the intention was to involve the environmental problems into other political questions (agricultural, energy and transport policy, etc.). Today the strategy-builders have given up the sectoral view because of difficulties and setbacks, and use a view aiming the problem.
    Agri-environmental issues appear as the elements of sustainability in the national strategies. For example, in accordance with the danger of global warming, the emission of green-house gasses of agriculture; in line with eco-efficiency, the production of renewable raw materials and energy sources originating from agriculture, and, in relation to changing lifestyle, food-safety and the future of biological agriculture will be disputed. With this study, I investigate the main characteristics of sustainable development strategies at both the EU level and at the level of the different member states from an agri-environmental point of view.

  • Pathogenic fungal pathogens and diseases: a mini review of effects on maize production
    93-102
    Views:
    1

    Maize, the most important cereal globally in terms of nutrition and income, is highly susceptible to biotic stresses caused by various pathogens, including fungi, bacteria, viruses, nematodes, and parasitic plants. This review gives an account of the epidemiology, diversity, and effect of fungal diseases on maize, with a focus on common pathogens, namely Ustilago sp. and Fusarium sp. Additionally, the review explores the major contributors to the pathogen and disease development, namely: soil quality, temperature, and humidity. Clarity is made herein about the damages and effects on maize growth, including development, yield, and grain quality, with marked economic losses recorded annually. The increasing threat of climate change escalates the dangers, pointing out the urgency for sustainable control strategies of the diseases. Conventional methods of using chemicals have been rendered inadequate for maize fungal disease control, underscoring the need for applying biopesticides and natural products obtained from microorganisms as innovative, remediation strategies. Together with these innovations are biocontrol agents that provide better solutions for reducing the reliance on chemical formulations as well as strengthening a healthier agricultural environment. Finally, a comprehensive understanding of the interaction between maize pathogens and environmental determinants is vital for the development of more effective integrated pest management strategies to enhance maize productivity and subsequent food safety.

  • The current status, challenges and prospects of native pig production and large-scale farming in Laos

    This review aimed to investigate the potential native pig development and the trend that large-scale farming may influence native pig production in Laos. The review found that native pigs were estimated to be around 88% of the total pig population in Laos in 2023. Commercial pig farming was found only in the main cities, particularly the central and southern provinces, which increased from 578 in 2019 to 703 farms in 2022 and 737 farms in 2023. Due to the serious economic crisis starting in 2021, many Lao pig producers stopped their businesses, leading to the decline of the commercial pig population by almost 30% in 2023 compared to 2022. The average pork per capita consumption in Laos in 2021 was estimated at about 14.2 kg. Though not as high as the backyard, commercial farms still contribute essentially to the pork supply in Laos (12%), increasing the volume from 87,628 tonnes in 2015 to 137,775 tonnes in 2024. The main native pig producers are small-scale rural farmers who have not yet improved productivity or reproductive performance, and the main purpose of their production is household consumption rather than market orientation. However, farmers, mainly in the main cities, improved them by cross-breeding native pig sows with Duroc boar for better lean meat. The main challenges for native production in Laos include poor farm setup and management, high cost of commercial feed, and poor breeding and genetic management. Therefore, creating awareness of the benefits of setting up a pig farm and management, providing better option strategies for utilising locally available feeds, and providing better strategies on pig breeding could improve native pig production in Laos.

     

  • On the Knowledge of University Students About the Strategies of National Sustainable Development

    The definition of sustainable development has a past which spans two decades. Today it is evident that the three pillars of sustainable development – environment, economy and society – have a strong correspondence and equally effect on every people. The UN’s Environment and Development Conference in 1992 declared the requirement in the document of Objectives for the XXI. century, that governments should prepare national sustainable development strategies. The World Conference of Sustainable Development in August 2002 made a stronger decision: „the states should make immediate steps forward … defining and preparing their national sustainable development, and for the purpose to start its realization until 2005”. Most of the countries fulfilled these requirements, and the Hungarian government promises to prepare its national strategy by the end of 2004.
    The aim of my study is to survey the knowledge of university students about the above mentioned process and generally about the topic of sustainable development. The selection of the target group is justified by the importance of young intelligentsia in the future. In order to examine their knowledge, I prepared a questionnaire and from the emerging primary data, my conclusion and statements have been deducted by a processing-analysing course, on the bases of which I made my suggestions.

    Rural tourism was a popular sector of tourism development in the last few years. The importance of this sector means that it can be developed on its own or together with other tourist sectors.
    The future of rural tourism depends on the supports of the national plans and strategies and the sales systems to keep on the market. In this study, I analyze how the Hungarian National Tourism Development Strategy deals with rural tourism and sustainable tourism. I also analyze how the big Hungarian travel agencies’ sales help rural tourism to advertise lodgings, and raise the number of sales. For the future, I analyze the opportunity of using travel agencies to sell rural tourism products.

    Termites are among the most destructive maize pests worldwide. A significant amount of research has been conducted on termites in Uganda but information on the incidence of termites is rarely updated. However, termite incidence, and associated perceptions in different geographical areas is important for development of sustainable control strategies. Therefore, this study was conducted to ascertain the prevalence of termites in Eastern Uganda and the possible ways to control their damage to crops. Data was collected from 272 respondents using face to face interviews following a questionnaire in the nine districts of Pallisa, Mayuge, Manafwa, Bugiri, Butaleja, Sironko, Kapchorwa, Bukwo and Luuka. Results showed that termite prevalence was very high in all districts with some recording 100%. Termites belonging to Macrotermes spp. predominantly affected maize. Mixed responses were recorded on cropping system effect on termite infestation implying that respondents couldn’t tell easily whether the cropping system reduced/increased termite attack. Percentage lodging due to termite attack was significantly higher (P=0.026) in late planted maize. The most dominant termite control strategy among the maize farmers was use of chemicals. Close to 50% of the respondents had never received any information on termites prevalence and management. Therefore, the study recommends more sensitization of farmers on management of termites with emphasis on cost effective and environmentally friendly management practices especially integrated termite control.

    The system of local sustainability strategies is shaped by the intentions of the central government and local initiatives together. From the aspect of the hierarchy of government organization in Hungary it means that there are institutions on the central government’s side – different ministries or other governmental institutions – the role of which is mainly coordination; and local governments (regional and local as well) also form their institutions at the municipality.
    It is important to examine the institutional background, as in Hungary the formation of sustainability policy is still in its infancy, so it is well worth taking the institutional background of countries the circumstances of which are similar to ours and have successful sustainability policies as a basis. In this presentation I will examine whether the top-down or the bottom-up approach is chosen, which institution is in charge of the process, what the legal background is like, and what sources are available for use in these countries.

  • Biomethane production monitoring and data analysis based on the practical operation experiences of an innovative power-to-gas benchscale prototype

    Power-to-gas (P2G) is referred to technologies that convert carbon dioxide into methane. Both bio- and chemical catalysts may be used for conversion purposes. One of the most disruptive biotechnologies was developed by the University of Chicago (IL) (publication number: EP2661511B1), using a robust, highly selective, patented strain of Archaea. Electrochaea GmbH has developed an innovative bench-scale P2G prototype unit, which uses this highly efficient Archaea strain, specialized components and specifically developed control strategies. The structure and the components of the prototype are equivalent with the functional parts of the currently largest commercial scale biomethanation BioCat plant located in Avedøre, Denmark (www.biocat-project.com). Power-to-Gas Hungary Kft. has committed to further develop this innovative technology. The first steps of this development have been taken by operating the benchscale unit and analyzing the data of the operating periods.

    The prototype is operated based on weekly campaigns. During continuous operation, H2O is generated as a by-product of methane. Therefore, approximately 200 ml of biocatalyst is discharged each day and concentrated media containing macro and micronutrients are injected into the reactor to maintain media composition. The laboratory staff records all gas composition data each morning. The gas composition is measured every 12 minutes by an Awite AwiFlex Cool+ gas analyzer. Within this article, we analyze the collected datasets containing more than 12 000 records and present the first practical experiences of the operations of the innovative power-to-gas bench-scale prototype.

    The analysis of the collected gas composition data of the product gas already provides important data for modelling the commercial-scaled processes. The average value of VVD was about 40 l/l/d in the period under review. Further increase of the methane content can be achieved by introduction of higher mixing energy and by increasing pressure levels in the bioreactor (as demonstrated in the BioCat plant – data not shown here) – both of which are strategies envisioned for the commercial plant. In routine activities (turn on, shut down, continuous operation) we could verify the high robustness of the biocatalyst and the base connection between the registered datasets and performed test results.

    This study aimed to assess the level of awareness and adoption of nurse sow management strategies among small-scale pig farmers in Nakuru County, Kenya. The research included a survey of pig farmers who visited the Nakuru Agricultural Show in July 2023. A total of 139 farmers were interviewed within 5 days of the show. The corresponding author interviewed the respondents in a face-to-face engagement, where questions on nurse sow management were initially drafted in English and translated into Kiswahili, i.e. the second language in Kenya. The obtained results indicated that farmers came from two main regions of the county: the northern part (54.7%, 76/139) and the southern part (45.3%, 63/139). Levels of awareness and adoption were insignificant between the two groups (χ2, p<0.05). A major obstacle to the adoption of this strategy was identified as feed challenge at 77.7%; (108/139) and market issue at 59.7%; (83/139). This study identified important aspects and limitations that should be considered when developing sustainable productivity development strategies for Kenyan pig farmers. To assist the sustainable growth of small-scale pig production, the authors suggest government measures that shield farmers against exploitation of feed and marketing components, as well as advocating for effective breeding to increase live born.

  • Conceptions regarding sustainable agriculture – the national sustainable development strategy

    The task of the national sustainable development strategy is to provide a long term conception for the economy and society, so that this might function and develop in harmony with the environment. Creating the conditions for sustainable agricultural production requires the elaboration and implementation of long-term programs spanning generations. The objective is to find a compromise between the conceptions appearing in the long-term and the short-term programs.
    In Hungary, several principles, conceptions and proposals have been suggested regarding sustainable agriculture. In the present study, I intend to systematize the above mentioned principles and conceptions, and compare them to the conceptions regarding agriculture in the national strategies of the EU member states. Furthermore, I examine to what extent the agricultural policy of the European Union supports the conceptions regarding agriculture in the strategies. This topic deserves special attention, as the Hungarian national sustainable development strategy is being prepared and is supposed to be finished by the end of 2005.

  • Challenges – the impact of climate change on the nutritional management of Hungarian orchards

    The agricultural sector is increasingly exposed to both environmental and economic risks due to the phenomena of climate change and climate variability. Fruit growth and productivity are adversely affected by nature’s wrath in the form of various abiotic stress factors. Climate change and extreme climatic events are predicted to increase in intensity, frequency, and geographic extent as a consequence of global climate change. It is no doubt that frequency of unexpected climatic events and their growing rate result in an increasing amount of problems for fruit growers globally. Today, climate change impacts are the most serious problems for Hungarian fruit growers as well. It can be stated that the nutrient demand of fruit trees can be supplied only under even worse conditions.

    Therefore, it is so important to know and apply adaptation and mitigation strategies in horticulture to improve fruit quality and yield. In the last ten years, at the Faculty of Agricultural and Food Sciences and Environmental Management at University of Debrecen expanded studies have been made to prove the importance of groundcover management in horticultural applications. In this mini review paper, is presented, how the university's researches contributed to the expansion of knowledge of preservation of soil moisture and what advice we can provide for fruit growers to face the challenges of climate change.

    Virtualization is increasingly taking on a key role in various system architectures which follow new platform concepts like Software as a Service (SaaS). This trend addresses more instant and short-term environments and comes with new methods and strategies for the distribution of mainly complex application stacks not only in large IT infrastructures. The paper presents how a so called Virtual Appliance can be set up in order to operate in virtual server environments using hypervisor software like Oracle Virtual-Box. Using the example of two server-side components within the Integrated Land Management System (ILMS), it will be shown that the use of state-of-the-art methods, standardized tools and interfaces on servers enables different aspects of environmental system management, analysis and planning.

  • Routine microscopy examination of faecal samples as a tool for detection of common gastrointestinal parasites: a preliminary report from two Hungarian farms

    Gastrointestinal parasitism in ruminant animals is a cause of major economic loss incurred by the livestock industry. Regardless of the frequency of the adopted therapeutic and prophylactic deworming strategies, the parasitic burden in a farm should be assessed regularly. One of the most widely used techniques to do so is the microscopic faecal egg examination and faecal egg counting method. Despite the technique being almost a century old from its first adoption, the principle behind the newer techniques of faecal egg examination is the same. This technique is still being used in routine farm screening and monitoring gastrointestinal parasitic load and faecal egg count reduction testing to assess the anthelmintic efficacy of the drugs used. Thus, the tool remains a choice for preliminary screening for important parasites and the subsequent deworming strategy. Our study here was part of a larger survey on the treatment efficiency as well as a broad epidemiological study of the trichostrongyle parasites in Hungary. We present a preliminary report on the detection of common gastrointestinal parasites from two farms in Hungary, including a species-specific confirmatory microscopy for Haemonchus contortus eggs.

    The constat growth of the Earth’s population brings with itself a higher demand for food and protein not only in human nutrition but also for the feeding of livestock. Currently, the feed industry is mainly built onseed-based protein, wherethebaseplant is soybean, which is large lycovered by imports in Hungary, similar toother European countries. However, the long-term economically sustainable lifestock breeding demandschanges which has also worked out strategies. An alternative protein sources could be green leafy plants.

    In current work the Jerusalem artichokes as an alternative source of protein was studied, compared to alfalfa as a valuable protein plant. Our results indicate that fiber fraction ofJerusalem artichoke shootswas 34 to 37% after pressing in the autumn period while alfalfa slightly lower values were obtained (30%). On the other hand extracted green leaf protein concentration was higher in alfalfa than in Jerusalem artichoke. Along with this higher protein content could be measured from the leaf protein concentration of alfalfa and almost each amino acids were more, as well comparing to Jerusalem artichoke.

    Overall, the alfalfa proved to be advantageous as expected both in leaf protein extraction efficiency, both regarding the content of the protein in the Jerusalem artichoke. However, considering aminoacid composition and green biomass production, Jerusalem artichokecould be a promisingplant species asplant protein sourceinthefuture.

    Conducted are researches of dynamics of glutathione reduced form maintenance in the leaves of arboreal plants which grow in the zones of different level of contamination by industrial emissions of“Red Lead Factory” LTD and ArselorMittal Kryvyi Rig. For comparison, similar  investigations were conducted in the intact Botanic Garden in s.c.t. Sofievka. Findings testify to absence of negative influence of industrial emissions and, thus, the arboretum of botanical garden also can be examined as conditional control. It was stated that it is set a few strategies of active oxygen forms and their metabolites deactivation, appearing in cells under action of environment negative factors. To our opinion, fluctuation of glutathione reduced form maintenance can examine as an index of plants stability, on which investigational species can be distributed on steady and moderato steady.

    Tourism has an important role in the various development plans and strategies around the world. It has also become an important component of rural development programs, as rural communities experiencing serious economic downturns often consider tourism to be a possible way of development. The expected positive economic and social impacts may not occur and negative tendencies are reinforced if communities do not support or even oppose tourism development. For this reason, it is highly important for planners and decision-makers to understand how the public perceives the tourism industry.
    In the international literature there is a growing number of studies about residents’ attitudes toward tourism development. In the present study I review the social and economic factors that influence the attitudes of residents and communities, as well as demonstrate the typologies that were created on the basis of the results. Finally, I summarize the theoretical models that are used to interpret the results of the investigations.

    The common smut of maize (corn smut, Ustilago maydis /DC/ Corda) can cause large economic losses in susceptible sweet corn hybrids as well. The protection against this pathogen is fundamentally based on prevention. Many methods to control corn smut have been recommended or evaluated, including crop rotation, sanitation, seed treatments, modification of fertility, and biological control. In spite of these frequently mentioned control strategies, the host resistance seems to be the only effective method to manage common smut in those areas where Ustilago maydis is prevalent.

    Due to the exhaustion of the fossile fuel reserves of the Earth, the increase of fossile fuel prices and the difficulties concerning stable fuel supply, the increase of electricity production from renewable energy sources has a special strategic importance. In this study, I am going to evaluate the circumstances of the production and use of renewable energy sources in Hungary and in the European Union. I present the Hungarian economic, energy policy-related and social circumstances which make it necessary to support renewable energy production. I am going to give an overview on the related EU strategies concerning the sector and the Hungarian development plan in this field. I pay particular attention to the examination of development opportunities and the R&D activities going on in this area in Hungary, as well as the efficiency of the means used to improve renewable energy use.

  • Impact of the integration of lupine (Lupinus albus) into crop rotation on the extent of soil compaction in the Westsik longterm field trial
    529-537
    Views:
    236

    In order to reduce or eliminate soil compaction, rational crop rotation and appropriate sequence of crops have an increasingly important role in addition to mechanical and tillage solutions. In this respect, introduction of greening in recent years has been a major step, which focuses on aspects of environmentally conscious, soil conserving farming and the improvement of biodiversity. The cornerstone of this strategy is the cultivation of crops that have a beneficial effect on soil properties, such as the use of nitrogen-fixing plants and green manure plants in the cultivation system that have a beneficial effect on soil structure. In our examinations, penetrometer measurements were carried out in the second longest crop rotation-based field experiment in Europe in order to quantify the effects of green crops and crop rotation strategies on soil resistance. Our aim was to evaluate and compare the impact of lupine (Lupinus albus) on the penetration resistance of soil on sour sandy soils. At the time of the penetration resistance measurement, different crop rotations had a significant effect on the development of the parameter in the examined soil layer. The most favourable penetration resistance values were found in the crop rotation, which included lupine as a green manure. The favourable effect is dominant below the cultivated layer (0–40 cm), which is statistically verified. The values of penetration resistance of the cultivated soil layer of lupine sown as primary green manure did not differ significantly from the values measured in the case of the fallowing-based crop rotation. Therefore, the use of lupine green manure instead of fallowing could be worth considering by practical application due to its favourable effects on soil penetration resistance. The use of lupine green manure after the production of rye cultivation resulted in penetration parameters similar to fallowing, irrespective of the green crop and the applied amount of nitrogen fertilizer, which justifies the cultivation of the crop as green manure. In the case of potato cultivating, recorded compaction within the cultivated layer is an obvious consequence of mechanical compaction during harvest; therefore, machinery operations are decisive for the development of penetration resistance values of the cultivated layer. In addition to the beneficial effect of lupine as a green manure crop on soil condition, its nitrogen-fixing ability is also important; it stresses the utilisation of the crop of sour sandy soils for the sake of proper soil management.

    variance and a two-factor linear regression analysis.

  • Understanding leptin’s influence on calf development: A review of metabolic and reproductive mechanisms
    145-153
    Views:
    469

    Leptin, a hormone primarily produced by adipose tissue, regulates the energy balance, metabolism, and reproductive functions. This review explores leptin's role in calf development from embryogenesis to puberty. Leptin expression is strongly influenced by the nutritional status, with circulating levels dependent on adipose tissue mass and modulated by metabolic hormones such as insulin and glucocorticoids. It plays a regulatory role in the embryonic cell division, adipogenesis, and postnatal energy metabolism. Additionally, leptin modulates appetite, the growth hormone secretion, and the reproductive system maturation. Its presence in the colostrum and milk highlights its significance in the early calf development, influencing the neonatal metabolism and immune function. As calves approach puberty, leptin serves as a key metabolic signal for reproductive maturation. A deeper understanding of leptin’s multifunctional role in calf development could contribute to improved livestock growth and reproductive management strategies.
