    256

    The aim of establishing a National Land Fund was to realise the rational management of land property belonging to the Hungarian State, to assist in the realisation of estate political directives, and also to support the development of a modern property structure based on family farms. During this 3 years operation the National Land Fund has become the major player of the Hungarian land market. It has arranged land trades totaling 15,000 hectares, which makes 50% of total related turnover. The NLF created the reason for the existence of land as credit security with the provision of security of mortgage credits. National Land Fund has written co-operation contracts with 11 commercial banks in order to provide long-term agricultural mortgage with the background of land security. NLF has issued almost 1,000 conditional declarations of land purchase to the banks, helping the credit system of agricultural companies.
    The valuation system „TÉR” created by the National Land Fund, is a many-sided, flexible system adjusted to Hungarian conditions. This evaluation system can determine the value of land in a reliable way. NLF built further controls into the process with the co-operation of independent revisers providing real determination of land value.

  • 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.

  • The managerial aspect of the police’s organizational development

    During my research, I have studied the relationships of the organizational development and the managerial functions at a specific governmental agency, the police. The police carry out official activities, but also provide a service which essentially assumes two types of contact systems and modes of management. To meet the demands of the citizens and to ensure the effectiveness of the organization, it is necessary to develop the managerial methods applied at the police, on the one hand, and to use certain parts of the organizational development, on the other hand.

    The police organization has changed significantly after the integration of the Police and Border Guards. The complexity of the structure and the anomalies in the work load, as well as several researches conducted by myself directed my attention to elaborate an organizational development method that can be applied to the current organization, while it improves the operation of the organization.

    The police’s operation and its organizational structure are determined by the laws, thus changing the structure of the organization is placed within relatively narrow limits. The police managers have the soft parts such as human resource development, skills, and management style at their disposal to develop the organization, but their use is isolated and they are not for a long term. The present article aims to present the set-up model related to the organizational development of the police, elaborated by myself, in terms of the leadership and the management styles, whose long-term use may contribute to the efficiency of the operation.

    Today, c for agricultural use are of ever increasing significance. These provide an opportunity for more accurate planning, and favourably influence the efficiency and economic performance of given enterprise. The relevant literature divides models according to various criteria. The most common is the division between optimising and non-optimising models. Non-optimising models generally endeavour to make the best use of technological lines, machine capacity, while optimising models are used to optimise revenue returns from sales or, occasionally, production costs. In our case, revenue and returns from sales were optimised. The models examined consist of several modules. Which include the following: plant cultivation modules, evaluations (assessment of situation, conception plan, complex corporate evaluation), supplementary sheets (sheets and charts for ancillary plant production, general costs of operation, summary and crops structure optimisation). With the help of the model, annual a particular can be made for an optimal crop structure the resources of the enterprise. This it becomes possible to define the largest net revenue on a corporate level.

    Nowadays, Science Centres, which have a very long tradition in Europe, are continuously spreading in Hungary. These institutions primarily aim at raising public awareness of science in young people via informal learning (hands-on, minds-on etc.) methods. Based on this phenomenon, the construction of Scientific Adventure Park has been started in the Debrecen Botanical Garden. In addition, the Municipality of Debrecen established a new organization who will be responsible the reaching the defined goals and sustainability of Debrecen Science Centre according to the Application Form. Therefore, it will be designed a new institution with characteristics of Science Centre and provide innovative and complex services in the segments of culture and education. In this paper, I'm searching for answers to the question if based on this process-oriented method and  management approach; it is possible to design operation system capable of achieving the strategic goals mentioned above.

  • Study on Human Resource Management in Agriculture

    The human factor has been reassessed with regard to strategic initiatives towards obtaining and preserving competitive advantage. Knowledge, experience and special skills are a specific form of capital, forming part of the organisations’ assets and serving as an organisational strategic resource. Their development and use require major investments, both on the part of the individual and the organisation. In a Europe undergoing integration, the quality of human resources enjoy priority among our really important values and specific features. The opportunities of the near future can be utilised, and agricultural economic organizations can survive and increase their organizational effectiveness, if they possess a basis of human capital which is able to make a shift in perspective and behaviour which is of primary importance from the point of view of incorporating market mechanisms and implementing them in practice. My investigations were focused on the current position of human resource management in a comprehensive manner; further, on the approach of top managers regarding the future. Analysing the business and other indicators of the companies studied, I have set the objective to describe the differences and special features of the human resource management practice of companies, which are different in size, operational form, and from the perspective of success or failure.
    Human resource management is directed to attracting, retaining, motivating and utilising labour. A given work process can be successful or unsuccessful – given the same conditions – depending on who performs it. Therefore, human resource management related tasks require special attention when enterprises are planned, established and operated. On analysing the responsibilities of human resource management, I have found that the functions and responsibilities of human resource have low or medium importance in the operation of economic organisations today. Regarding the future, top managers have expressed higher expectations of human resource management responsibilities in all areas and they consider individual functions to be more important. The establishment and operation of a human resource information system has been presented as the most important need for change. Correlation analyses have proved that the higher the sales revenues of a company, the higher the development of human resources is regarded by its manager, and the same holds for training, career support and a proper establishment and continuous evaluation of job profiles.

    Planning, implementing and inspecting forestry operations require more extent application of certain assessment methods. These methods may need to be improved and, in some cases, their simplification is necessary in order to ease their usage in practice. Knowledge and application of auxiliary tables and functions, data on volume and methods to estimate yields are needed for the planning of any kind of forestry operations, depending on the level of planning. The main purpose of this paper is to propose relatively rapid and simple methods to estimate the volume at thinning and final cutting, and the gross above ground volume at the harvest of black locust (Robinia pseudoacacia L.) stands, as well as to introduce tending operation models tailored for black locust. All these measures could be beneficial to forest authorities and foresters who are responsible for planning and production.

    Nowadays, the importance of marketing is increasingly obvious. The number of those who apply those possibilities and methods provided by the marketing with which more efficient operation and higher amount of profit can be obtained is increasing. Special marketing fields have appeared that make the marketing characteristics of the single trades, product groups and industrial branches are widely known and utilized. During the more than 10 years following the changes of regime, the Hungarian wine market underwent a huge change. It is obvious, that this process has not stopped, and further market rearrangements may be claimed. The product and price policies have changed. Out of the marketing mix elements, mostly the marketing communication has changed, and the costumer has come to the centre. This marketing approach resulted in the formation of the newly established Hungarian Wine Marketing Public Benefit Company. The common marketing activity of the organization should have positive impacts on the industrial branch, although its efficient operation still has hindrances

    Our research aimed to examine Hungarian automatic drinking system constructions and hydromechanics under laboratory conditions and in operation with special emphasison the small volume, valve types.
    Considering that no Hungarian standard of automatic drinking system examination and qualification exists, on the basis of technical literature, the new examination method of automatic drinking systems has been elaborated.
    For laboratory measurements, a universal measuring bench was assembled which is applicable to the hydromechanic testing of all automatic drinking systems (cattle, sheep, pig).
    Summary of the laboratory measurements:
    Upon comparison of the flow capacity of the valves, in the case of same opening values (h/dn), the rubber spring valve of SZI type automatic fountain has the highest flow capacity, although in the case of 100 kPa pressure even this type has only 15-16 l/min value which hardly surpasses the lower limit of the desired 15-25 l/min range.
    The loss coefficients of the valves, on investigating in the range 100-200 kPa, showed the lowest value (2,2-5,8) with the steel spring self drinking device.
    Summary of the operational investigations:
    In the long term operational investigations, the rubber stripped valve and the rubber spring automatic fountains had the most favourable operational reliability values: K4=0,98 and K4=0,94, respectively.
    From the aspect of animal operation of the valves, all the Hungarian types are frontal operated, thus such system automatic valve drinking devices can be used only in long and moderately long stands, directed toward the animal.
    On the basis of hydromechanical and construction examinations of the Hungarian tied cattle production technology the construction modification of the rubber spring valve of SZI type automatic drinking fountain, which is the most frequantly used in this country, was carried out. Due to design modifications the valve parameters improved significantly.
    The goals of the accomplished valve modification were
    ζ'sz – loss coefficient to be reduced
    q – flow capacity to be increased

    The authors of this study seek the answer to the question how to develop, in the first decade or decades of the 21st century, the university-level
    horticultural scientific training, the horticultural innovation and the scientific co-operation between companies and universities in Debrecen and
    in the North Great Plain Region and – in a wider sense – in Hungary to a standard being competitive even in European terms. With the synthesis
    of the prospects of past, present and future, they drew the following conclusions. The reconstruction of agriculture, horticulture and food industry
    is a part of reforming Hungary's countryside. Horticulture, producing high added value, will be able to decisively contribute to the plan whereas
    the value presently produced in an agriculturally cultivated area of 1,000 euros/hectare can reach 2,000 to 3,000 euros in the next two decades.
    A necessary and indispensable precondition to achieving this is the strengthening of the innovation output of the Hungarian horticultural sector.
    Despite the numerous technical criticisms formulated in connection with the serious problems of Hungarian agricultural and horticultural
    scientific innovation, no progress has been made in this field for the past one and a half decade. The scientific research of this topic hardly
    continued or did not continue at all, the up-to-date surveys and in-depth analyses were missing. The objective, basic principles and tasks of the
    Act CXXXIV of 2004 (TTI) enacted concerning research-development and technological innovation are clear and progressive. The co-operation
    between the National Research Technology Office and the Hungarian Academy of Sciences, the setting up of the Innovation Fund are heartening
    opportunities. These – along with the new Higher Education Bill to be passed – may as well be suitable for restarting the Hungarian agricultural
    and horticultural scientific innovation. In our opinion, this requires a new, well-considered national agricultural programme, which can be
    conceived in the framework of the "Ferenc Entz National Horticultural Plan" proposed by us for horticulture. In the most eastern Hungarian
    university knowledge centre, at the University of Debrecen, the continuing of the horticultural scientific innovation strategy started in the last
    decade may be the focal point and generator of the development of the so-called "Hungarian Horticultural Triangle”, or "Hungarian
    Horticultural Cluster". This region comprises the Northern and Southern Great Plain Regions and the area between the Danube and Tisza
    Rivers. Here, about 70 to 75% of the total Hungarian horticultural commodity stock is produced. The objective of the HORT-INNOTECH
    DEBRECEN programme planned in 2004 by the University of Debrecen, Centre of Agricultural Science is to establish the horticultural scientific
    research-development and technological innovation structure and knowledge base of the Hungarian Horticultural Triangle / Hungarian
    Horticultural Cluster. In harmony with this, the objectives are to bring about competitive, new horticultural products, to improve the conditions
    of utilising them, to enhance the competitiveness of enterprises based on technological innovation, to make use of the research-development and
    innovation opportunities available in the regions in an efficient manner, to as full extent as possible, to encourage the creation of places of
    employment producing high added value in the field of horticulture, to improve the technical skills of those employed in horticultural researchdevelopment and to promote their enhanced recognition by the society.

    The income of agricultural enterprises varies greatly according to the type of agricultural production. The available data was classified and averaged on the basis of the form of association.
    Although the management of the examined enterprises ensured a profit, closer analysis of their cash flows reveals that, at least in some cases, expenses were not always coverable, despite income. In all forms of association major emphasis was put on improvement and support investments. It is highly probable that later on these investments will result in an increasing income level and profit. The situation is the most advantageous in the case of co-operatives, as the cash flow of the second examined year originated from regular activity could cover the cash flow of investments and financing. In the case of limited liability and shareholder companies the above is not true, but advantageous changes occur there too. Unfortunately, in most cases the role of loans is very important in the operation of the company. As far as favourable aspects are concerned it can be stated that credit repayment covered by the regular activity.

    I introduce the performance management from the area of human resource management that I examined at organizations operating in market environment and in the public sphere as well. The reason of my choice of subject is that the performance management got into the centre of interest also in Hungary lately.
    The scale of values connecting traditionally to the organizations of the private and public sphere is different vitally, what affected substantive differences of the organization, the management and the human resources management environment. Within these I tried to reveal their performance management system and with their comparison to draw conclusions. I did my surveys at profit oriented organizations and at organizations operating at the public sphere.
    Performance management is one centre field of modern human resource managing, as the basis of the successful functioning of any company is the possibly most effective operation of its resources. Performance management is a possibility for the company and for the employer to overview the realization of the determined aims and the factors that block or promote accomplishments. Considering the results, the employee and the manager could determine subsequent realistic and accessible aims for the following period. Achievement management is extremely
    important in those positions where achievement could not be measured accurately.
    I carried out my surveys according to performance management by observation and data acquisition. I applied questionnaire survey to collect data, or rather made deep interviews; I talked personally with more employees as well.
    The questionnaire consisted of one data format and performance management questionnaire. I processed the gathered data by computer and visualized graphically. I also did examinations by using statistic methods, by which I was able to get to know the certain organizations deeper and thus it was possible for me to reveal more connections.

    The effect and interaction of crop production factors on maize yield has been examined for nearly 40 years at the Látókép Experiment Site of the University of Debrecen in a long-term field experiment that is unique and acknowledged in Europe. The research aim is to evaluate the effect of fertilisation, tillage, genotype, sowing, plant density, crop protection and irrigation. The analysis of the database of the examined period makes it possible to evaluate maize yield, as well as the effect of crop production factors and crop year, as well as the interaction between these factors.

    Based on the different tillage methods, it can be concluded that autumn ploughing provides the highest yield, but its effect significantly differed in irrigated and non-irrigated treatments. The periodical application of strip tillage is justified in areas with favourable soil conditions and free from compated layers (e.g. strip – strip – ploughing – loosening). Under conditions prone to drought, but especially in several consecutive years, a plant density of 70–80 thousand crops per hectare should be used in the case of favourable precipitation supply, but 60 thousand crops per hectare should not be exceeded in dry crop years. The yield increasing effect of fertilisation is significant both under non-irrigated and irrigated conditions, but it is much more moderate in the non-irrigated treatment.

    Selecting the optimum sowing date is of key importance from the aspect of maize yield, especially in dry crop years. Irrigation is not enough in itself without intensive nutrient management, since it may lead to yield decrease.

    The results of research, development and innovation, which are based on the performed long-term field experiment, contribute to the production technological methods which provide an opportunity to use sowing seeds, fertilisers and pesticides in a regionally tailored and differentiated way, adapted to the specific needs of the given plot, as well as to plan each operation and to implement precision maize production.

  • Overview of the evolutionary history and the role in citric acid production of alternative oxidase
    83-88

    All organisms are exposed to countless environmental effects, which influence in a disadvantageous way their life processes. They continuously adapt to the changing conditions and respond to the stress impacts by defence mechanisms. Through different signal transduction pathways they are able to increase or decrease the expression of their genes and consequently modify their metabolic processes. My interest focuses on alternative oxidase (AOX) enzyme whose expression is often increased under biotic and abiotic stress. The so far proven and putative functions of the AOX play a role in the ability of organisms to adapt to different conditions, such as heavy metals accumulation, pathogenic infection, oxidative stress and lack of oxygen or nutrients.

    AOX is a member of the di-iron carboxylate protein family. Members of the di-iron carboxylate protein family are present in all kingdoms of life. They are considered to have ancient origin. It is believed that their sulfide-resistant and oxygen-reducing ability played a role in the survival of organisms during the transition between the anaerobic and the aerobic world. It is assumed that the AOX arose in eukaryotes through a primary endosymbiotic event, and this event made possible the development of mitochondria. Afterwords, vertical inheritance, and secondary and tertiary endosimbiotic events led to its spread among eukaryotes. It is assumed that bacteria obtained AOX by horizontal gene transfer from plants.

    AOX-catalyzed alternative respiration plays an important role in the operation of energy-producing and biosynthesizing system of microorganisms. In these cases, the regeneration of reduced cofactors is an essential condition, and therefore may be rate-limiting for biotechnological processes, including the citric acid production.

    In countries struggling with timber shortage, including Hungary, fast-growing tree species such as black locust (Robinia pseudoacacia L.) offer the possibility of meeting an increasing proportion of timber demand from domestic sources through more efficient use of cultivation opportunities. Coppice forest management is the oldest, but also the simplest and, in most cases, the most cost-effective method of operation. In this paper, we present the timber production criteria for the coppice regeneration method, including the accelerated determination of the timber stock of black locust parent stands through case studies.

  • Coherence and connection between the good pond culture practice and the environment conscious management

    According 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).

    Because of the development of knowledge-intensive business activities based on innovation-oriented economic development which are specific to innovative SMEs, funding sources and opportunities. In a typical operating environment of innovation, with sectoral, spatial and temporal factors are constantly changing. These factors are decisive elements in the innovation opportunities, and through this indirectly the success of these enterprises. The resources involved in mediating the markets perceive a high risk to price this innovation activities and their funding. Under the study to try to answer that by optimizing the functions of universities, how and in what form they may have a role in mitigating financial risks.

    Aquaculture species such as fish, crayfish, molluscs and plats are a wide range of products, with continuously growing demand worldwide. The reasons for this is that they are cheap and easy-toraise protein sources, thus having significance in food supply especially in developing countries in tropic regions, moreover, the premium category foodstuffs in developed high income countries are also belonging to this category. World annual total production of 164 million tons (2009) are made up of two sources: 1) marine and inland fisheries landings that are stagnating for several years and 2) aquaculture which is growing dynamically with annual 6% rate between 2000–2009. The latter is accounting for nearly 45% of the total supply due to the depleting marine stocks caused by overfishing. Aquaculture is growing continuously also because the production is safe and can
    be planned well. 
    Intensive fish production systems are the representatives of precision animal production, several types exist and widespread worldwide. The modern computerized temperate water recirculation plants with several thousand m3 capacity are widespread also in Europe because they make it possible to produce even the most valuable species whole year round. A key issue in the technical/feeding outlay is to meet the demands of the cultured species the best and the operation of the system is to be safe and cost-effective. One condition for this is intensification: enable to produce more product per unit resource input or effort. The facilities need significant amount of energy, thus renewable energy sources are to be favoured for which Hungary has comparative advantages.

    The technology supervisions are needed from time to time in order to involve the new research results, experience, new technologies and equipments organising principles into the production and to make it cheaper and with less expenditure to increase the profitability and competitiveness. In the course of our investigation we aimed the analysis of the traditional technologies and improving of it. In this article we detail the heat treatment curing process. We applied the principles of experimental design for the determination the main influencing parameters in the processes. Then we made simulations and modelling in seeking for the environmentally better technology programs. We developed a method for measuring the temperature development of products with small diameter using the similarity theory in unit operation. In the course of the analysis of the heat treatment processes we could state that the heat treatment time can be reduced significantly by decreasing the size of the product and choosing the right ratios among the surface heat transfer intensity, ambient temperature and involving the lethality obtained during the cooling phase. The total sparing were about 10-20%. We solved the problem associated with the sensor placement error using a plastic material (metamid). We establish a curve between the real product temperature and plastic rod temperature by which the monitoring of the process became more accurate. We determine the size modification for different product sizes. In case of curing we observed very similar phenomena. For the determination of the diffusion coefficient we adopted the Ball-method not using in this field till today. We could reduce the excess saltiness and loss of NaCl with about 5%.

    services. The article presents the Hungarian electronic claiming system (called eSAPS) for European founds in agriculture, and evaluates the first year of its operation.

    Two main channels have been identified to be responsible for microbiological contamination of raw milk and milk products. Firstly, contamination has occurred due to udder infection from the cow or the blood which harbours most bacteria that come in contact with the raw milk. Secondly, via external factors (may include faeces, skin, contaminated water, environment etc.) which are associated with the operation of milking. There is direct contact with the milk and/or surfaces before, during or after the milking, posing public health risk and economic decline. The aim of this study was to examine the bacteriological quality of bulk tank raw milk samples collected from two different size dairy farms (Farm 1 and Farm 2) of different housing forms (cubicle loose and deep litter) in Hajdú-Bihar County, Hungary in July, 2017. Three samples were taken from each farm, and the total plate count, coliform count, Escherichia coli count, Staphylococcus aureus count, and yeast and mould count were determined in them.

    The results clearly showed low level of all measured bacteria group load in Farm 1 samples in comparison to Farm 2 with the exception of coagulase-negative Staphylococcus (CNS) which represented high level in general, indicating significant difference (P<0.05). The mean value of total plate count in Farm 2 samples was higher (1.0 × 105 CFU/mL) than Farm 1 samples (2.8 × 104 CFU/mL). There was a significant difference (P<0.05) in mean count of coliforms in raw milk samples between Farm 1 and Farm 2. Similarly, results of E. coli were significantly different (P<0.05) with mean count of 1.44 × 102 CFU/mL and 2.02 × 103 CFU/mL for Farm 1 and Farm 2 respectively.

    Results of Staphylococcus aureus also showed significant difference (P<0.05) with mean count of 9.7 × 101 CFU/mL for Farm 1 and 6.28 × 102 CFU/mL for Farm 2. The mean of mould count recorded was 1.07 × 102 CFU/mL and 4.93 × 102 CFU/mL for Farm 1 and Farm 2 respectively. The recorded mean of yeast count was 1.68 × 103 CFU/mL and 3.41 × 103 CFU/mL for Farm 1 and Farm 2 respectively; however, both farms showed no significant difference (P>0.05) in terms of mean of mould and yeast count. Although Farm 2 produced six times lower milk quantity than Farm 1, the measured microbial parameters were high. Both farms’ microbiological numbers were higher above the permitted limit values as stated by Regulation (EC) No 853/2004, Hungarian Ministry of Health (MoH) 4/1998 (XI. 11.).

    This could be an indication of non-conformance to effective GMP, ineffective pre–milking disinfection or udder preparation, poor handling and storage practice, time and temperature abuse and inadequate Food Safety Management System Implementation. Therefore, our recommendation is as follows; establish control measures for pre- and postharvest activities involved in the milking process which would be an effective approach to reduce contamination of the raw milk by pathogenic microorganisms from these farms, strict sanitation regime and hygiene protocol be employed and applied to cows, all equipment, contact surfaces and minimize handling of the milk prior, during and after milking. This will also serve as scientific information to the producers for continual improvement in their operations.

    Agriculture in Hungary was characterised by the duality of large-scale farms (co-ops and state farms) and small-scale private enterprises until the beginning of the 1990s. Due to the privatisation and transformation of co-ops farm structure has significantly changed. The transformation of the structure is not considered to be a completed process. Level of concentration and integration on private farms are rising, new co-operation forms are appearing and new types of enterprises and producers’ groups are being formed.
    Concentration and integration have great importance in the dairy sector among agricultural enterprises. In recent years, milk production in the European Union has been characterised by concentration, leading to greater competitiveness. Today, most dairy producers belong to different kinds of producers’ organisations as concentrated demand may only be competitive by meeting concentrated supply. In Hungary, the problems of production have been the fragmentation and decrease of the average farm size while, at the same time, concentration has occurred in the processing sector. Establishing producers’ groups may be one of the solutions for improving competitiveness production.
