Introduction of DNA-based Methods to Agriculture Through Molecular Taxonomic Examination of Poa Species
139-142Views:97biological methods, one among them is AFLP that is well applicable for taxonomic research. Bluegrass species, that are important components of meadow associations, thus their thorough knowledge is necessary in maintaining biodiversity, were examined with bringing this method to perfection.
Taxonomic relationship of the members of Poa pratensis aggregation is a controversial issue. Present study aimes to identify the members of this group, with a developed AFLP method through molecular taxonomic examination of Poa species in meadows nearby Debrecen, revealing their genetical distances. Species of the aggregation show a great genetic variability, but their genetic proximity approves the use of the term aggregation. Results established wider geographical investigation of three species of the aggregation. The distinctness of the species based on their morphological features was confirmed according to their genetical basis as well. The method overall turned out to be appropriate for the taxonomic research of bluegrass species like Poa pratensis and its aggregation. -
The scientific background of competitive maize production
33-46Views:294The 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.

The role of animal breeding with special regard to native pigs of food supply and rural development in Laos
149-154Views:250The present paper explored the influence of breeding native pigs on livelihood conditions and the contribution of native pigs to the rural development and rural poverty reduction in the rural areas of Lao PDR. Pig production plays an important role in meat supply for both urban and rural areas of Laos. It is clear that most of the pig products in the country come from smallholder pig farms, and more than 90 percent of those products are the native pigs mostly raised by farmers in remote areas. In general, livestock production distributed between 15–18 percent to GDP, while most of animal production still remains as the traditional methods. Rural development is always the first priority of the Laos government since its independence in 1975, however, the poverty rate in rural areas remained high at 23% in 2018. It might block the development goal of the government which will lead the country out of the least development status by 2020. The food security and malnutrition in the rural or mountainous areas are considered as the majority issue that both government and several international organizations have been thriving hard to overcome, which researchers showed that more than 45% of children under 5 years of age were stunted, and 28% of them were underweight. Inspired of more than 50 % of the households in the rural areas of Laos reported they consumed chicken and pork at least one day a week. While native pigs play an important role on meat supply, it also constituted around 9–14 % of annual income of the households in rural areas. Therefore, the increase the production of pigs and poultry is one option to promote the meat supply to households in the rural areas of Laos. This paper will be a pathway to guide and identify for the final decision to what experiment will be implemented on Lao native pig in Laos (2021–2023) to complete the comparative study on reproductive physiology and reproductive management methods of Hungarian and Lao Indigenous pig breed. Which found it still needs further afford to research and improve more about native pig performance for all areas of productive and quality management.

Congruency Analyses in Agricultural Organizations
56-61Views:70Management is one of the ancient activities. Managerial behaviour helped humans to become sociable creatures. The aims and roles of management have continually changed along with social and economic changes. Some management theories in the early literature interpret the managerial function as „to instruct” and „to control” subordinates. The manager – having the appropriate authority – unilaterally appoints the expected activities in accordance with the objectives of the organization and his/her own wish. Its form is the instruction or the command.
Later, organizations and management theories defined the managerial function rather as the impact on the employees than (or instead of) a unilateral manifestation of will. These focus on collaboration and imitation instead of on obedience. These theories were based on the fact that the employees work hard to succeed in meeting organizational goals because they want to meet their own needs, desires and wishes.
Today, management means being in a relationship with colleagues, effective and successful working methods and, last but not least, commitment and liability for the company. The responsibilities of directors are to estimate the employees’ competences and to apply the workforce expediently.
In our opinion, the two most important questions of human resource management (HRM) will be:
• the expectations made of the manager by the subordinates,
• the expectations made of the subordinates by the manager.
The expectations of management have continuously evolved along with the social, political and economical improvement. We consider the most important requirements will be the following:
• the exploitation of employees’ abilities (especially the leaders’),
• the exploitation of human resource,
• aim-oriented leadership related to different management levels.
The actual research covers only the examination of managerial requirements. We experienced that the expectations are affected by many factors starting with the fulfillment of a specific task to the social environment as a whole. Managements of the last century did not require such self-reliance, creativity and broad knowledge from their subordinates as they do today. Employees have to be able to adapt to new tasks, technology and methods; have to react quickly against the problems; and be loyal to the company and the manager.
We plan to expand our research backwards as well, in which we will search for the answer what kind of expectations are formulated by subordinates on the manager. Thus, we can approach and reveal the expectations (the examined factors) from two sides.
Due to this method, we would like to work out such coherences which can help us to demonstrate the opinions of the differently qualified employees of the organisations. The applied method provides us facilities to carry it out in various organisational parameters, such as functional form, size, effectiveness, range of activity. -
Environmental Management Research on the Berettyó River
161-165Views:66Our department is involved in ongoing research into the hydrological and ecological interplay of the Berettyó River.
In the first part of our study we classified the Hungarian section of the river from ecological and hydrological standpoints. We determined three typical parts of the river: a sandy and gravely bottom, a middle part with a sandy and muddy bottom, and a lower part, with muddy bottom. In theese sampling areas we measured and established the more important static and dynamic hydrological, physical and chemical characteristics.
For the planned research we did a primary estimation of the environmental condition of theese sampling areas, on the basis of applicable biological and ecological indication methods. -
Population date of Great Cormorant at the area of the Hortobágy Fish Farm Co.
51-54Views:244Hungary’s great cormorant stock did not use to be a considerable one before the 1980s. After that, their number has been rising significantly. The size of the stock now is rather stagnating or slightly growing. The presence of cormorants has been significant around ponds of the Hortobágy Fish Farm in the past few years. Due to considerable fish consumption of cormorants it is essential to know which and what kinds of units of the ponds (spawning, supply, and market) are preferred by the birds in order to see to adequate protection. The aim of our research was to discover any differences in the number of cormorants present at particular units of the fishpond system and certain ponds of equal kinds within them.
Our observations were in line with the methods used in ornithological researches. The experiment took place between April and October 2012 on a monthly basis. According to the results we found relevant differences in the number of cormorants based on the seasons and months as well. This fact was supported by statistical data. During the autumn and winter birds prefer supply and market purpose ponds while their presence here is vanishing during the summer. Relevant presence of cormorants around the area of the Old Fishponds (70 to 200 specimens) might be due to lack of disturbance and large sizes of the ponds.
Our research has great scientific relevance since it is vital to be aware of the preferred periods and areas in order to maintain effective protection; this way alerting activities can be applied in a more harmonized way. By keeping our research up as a monitoring activity, we will be able to receive more precise data later on.

Effects of paraffine oil on leaf and berry mycobiota on two grape varieties
61-66Views:200Application of fungicides have advantages and also some direct or indirect disadvantages, such as imbalance and/or fungicide resistance in microbe population. To avoid these problems the development of alternative, eco-friendly methods like mostly spraying with oils are in the focus nowadays. The investigations of the effects of fungicides on microbiota in some cultivations can give a more complex view to this topic and developmental possibilities. In the present study, our aim was testing of the effects of paraffine oil (as alternative fungicide) on microbial properties (CFU and rate of filamentous fungi and yeasts) of Chardonnay and Kékfrankos leaves and berries.
Our results from 2014 showed that the application of paraffine oil as sole spray agent can decrease the presence of saprophytic filamentous fungi on the berries of Chardonnay (susceptible for fungal infections). In the case of Kékfrankos berries opposite properties were observed, which may be the result of the absorption of oil by the thick wax layer of this variety. The oil treatment did not affect the yeast population of Chardonnay and Kékfrankos berries contrary to negative effect of the regular pesticide treatment. The selective fungicide effect of paraffine oil against filamentous fungal population caused the accumulation of yeast cells in the mycobiota of grape berries. The careful use of this yeasts in spontaneous fermentation can improve the aroma profile of wines. The year of 2015 did no prefer the growth of fungi, therefore no interesting properties were detected in the mycobiota of grape varieties. The occurence of the harmful saprophytic filamentous fungi predicted to be increased in mild climate agricultures as the result of the climate change.
In summary, the paraffine oils are seem to be promising tools for the eco-friendly control of harmful fungi of grapes.

Anti-Oxidants in Agriculture
195-200Views:89Today’s programmes aiming at enhancement of fruit and vegetable consumption have been intensified. In the unanimous view of experts, different health problems, such as those of the immune system, inflammations, and even certain cancerous diseases can be prevented and/or cured with regular consumption of fresh (raw) fruit and vegetables. It is well-known fact that among the biologically valuable components, antioxidant compounds – C- and E vitamins, as well as carotinoides – play an important role. In this field, Hungary can expect success in the future since it has excellent plant genetic stock. Regretfully, national data banks regarding cultivation technology, cultivation areas or varieties for fruits and vegetables and their antioxidant contents do not exist in Hungary. Nevertheless, in connection with the so-called “Hungaricums” its existence would be of urgent necessity. Such excellent Hungarian products are – among others – a lot of sour cherry varietiles, the Szeged green pepper and the Makó onion. They enjoy high priority as “Hungaricums” even in the European Union and such activities that support these kinds of products should be enhanced by intense and consequent research work, which may prove their role as functional foods. Presently’ the USA leads in the research of antioxidant compounds of sour cherry, and so far 17 of these compounds have been found partly in Hungarian varieties. Similar research on green, and ‘pritamin’ peppers have not gone so far since they were limited only for seasoning paprika. In Hungary, studies on onion and garlic have not been performed. It should be mentioned that due to the continental climate, these products may be cultivated, consumed or processed only in a limited period. Taking this into consideration, processing and conserving methods are needed which make the consumption of these fruit and vegetables as functional food possible year-round. Scientific establishment of this set of questions is of current concern, because consumption of these products could have an important role in improving the health status of the Hungarian population in the future.

Examination of CO2 emission of different stubbles on a chernozem soil
53-59Views:86Applying alternative soil cultivation methods based on reduced disturbance of the soil more favourable conditions can be created in order to increase the organic matter content of the soil and the availability of the nutrients for the crops. In complex soil tillage experiment – in 1997 was set on – at Karcag, as the element of the investigation of soil reduced and conventional tillage systems. There is close correlation between the degree and intensity of CO2-emission from the soil and the structural state and organic matter content of the soil. In order to quantify the increased CO2-emission from soil due to soil preserving cultivation systems, in situ CO2-emission of soil was measured by means of an ANAGAS 98 infrared gas analyser. The soil type of the investigated plot is meadow chernozem solonetz in the deeper layers, a soil type that is characteristic
for the Trans-Tisza Region of Hungary. In this paper the results gained from the measurement on different stubbles are published, as we consider stubbles the most suitable state when the effects of different soil cultivation systems on the microbiological activity of the soil can be compared. Experimental data provided information about the length of the time period when CO2 emission increasing effects of soil cultivation are observable. Studying the effect of different soil cultivation methods on the CO2 emission from chernozem soil is indisputably actual and needs more efforts as it can contribute to develop a more environmental friendly agricultural production. The main goal of these measurements was to determine the effect of soil cultivation technologies and certain agrotechnical elements on the factors of the soil carbon cycle. -
The examination of alveographical parameters of winter wheat varieties
87-91Views:125Nowadays, many methods have been worked up in the interests of objective expression of winter wheat rheological quality. These define wide spectrum in view of their complexity and apparatus claim. The needs for the methods are definitely increasing in Hungary, too. It is very important to get acquainted with the alveographical quality and qualification and also their using in wide range.
In our research we examined the alveographical parameters of 12 winter wheat varieties in Szeged (in Hungary) on the basis of the results in three years (2005-2007).
We established with correlation analysis that there is no statistical relation between the alveaographical W and G values. The other alveographical parameters have significant correlation. -
Effect of harvest on the different fertilization methods of asparagus (Asparagus officinalis L.)
33-37Views:141The experiments were performed in the University of Debrecen Centre for Agricultural Research Institute of Nyíregyháza of 1500 m2 asparagus plantation in 2011. We were determind the number of shoots, plant height, fold thickness and yield of asparagus hybrid. I studied to the effects of various cropyear is addition Grolim hybrid asparagus growth and development. Compared to previous years, 2014 was unusually wet and cold weather conditions which causes the plantation has developed outstanding. The soil temperature early and dynamic increase due to, the harvest had started a one month earlier 2014 than the 2013. The experiment asparagus harvested from lower yields as a result of the extremely dry spring in 2015.

Supplementary botanical examinations for modelling the grass production of the great pasture of Hajdúbagos
17-21Views:62Our botanical survey at the great pasture of Hajdúbagos is a part of a broad research that aims to predict the production of the grass at the given area. As the mentioned pasture is a nature conservation area, the usage of artificial fertilizers or other classic grassland management methods in its handling are prohibited. Thus grazing is an important tool for the management of this area, however the not suitably regulated grazing order and the poorly calculated carrying capacity cause serious problems at some parts of the pasture. The prediction of the grass yield is essential to
avoid both over- and both under-grazing and for determining the optimal number of the grazing animal stock and the grazing method, thus the most suitable management strategy.
The potential grass yield is easily calculable with a computer model that will be established as a basis for determining the grass production. For the sake of getting an accurate view of the plant associations of the pasture, we created examination quadrates and determined all plant species found in the quadrates. After plant determination, we compiled a coenological table in which we marked besides the scientific name and families, the life forms of each species that refer to the structure, morphology and thus the adaptability of plants to their environment. We determined the
TWR, so the thermoclimate, water and soil reaction values, the nature conservation values, as well as the covering values of each plant species (DB), and the total coverage of the examination quadrates (B%).
According to the covering values, grasses proved to be characteristic plants at the examined pasture, thus we need to consider them influential in calculating the animal carrying capacity and with the rest of the information, we need to supply the model.
The life forms and TWR indicators, all together with the nature conservation values provide further important data to the development of the management suggestion of the protected pasture. By examining these values to different parts of the area, we could get an exact view on the measure of the degradation effects. This promotes the determination of grazing methods and the forming of the boundaries of certain pasture sections, to avoid those harmful anthropogenic effects that seriously endanger this extensive sandy pasture. -
Composition and role of hoverfly (Diptera: Syrphidae) communities in an organic apple orchard
57-61Views:90The use of hoverfly (Syrphidae) larvae in biological control is gaining more attention where the damage by their prey, aphids is significant, especially in agricultural fields and orchards, where they lower the number of aphids. The present study focuses on one hand on faunistics, on the other hand on testing the different available collecting methods for later research. Collecting in an organic apple orchard near Debrecen yielded 525 specimens of Syrphidae mostly by netting but also with white tray traps. Collected species are differentiated according to their feeding (94.1% aphidophagous). The three species found in greatest numbers are Sphaerophoria scripta (Linnaeus, 1758), Melanostoma mellinum (Linnaeus, 1758) and Episyrphus balteatus (De Geer, 1776). The available information on their biology is reviewed and their potential value of hoverflies in biological control is discussed.

Sensitivity of methods for estimating reference evapotranspiration
51-56Views:147The knowledge of the evapotranspiration of natural ecosystems and plant populations is of fundamental importance in several branches of science, research topics and practical uses. Nevertheless, the harmonization of the large number of methods and the changing user needs often causes problems. Sensitivity analysis of 10 ET0 estimation models and model variants was performed. Magnitude of the obtained outputs and the changes triggered by each atmospheric parameter were evaluated. The objective of the analyses was to get to know the sensitivity of the different models and to select the most accurate and the most suitable ones for adaptation to local circumstances. Therefore, it becomes possible to achieve as high accuracy as possible in applications which need ET0 estimation.

Need for measurement of the innovation at Hungarian SMEs
5-13Views:137Competitiveness studies have shown that innovation could be breakout point for some economies, regions and enterprises. Knowledge acquisition, creation and exploitation of the knowledge base have been an essential element for economic growth. These knowledge-based economic processes come together with the innovation. Measurement of innovation by indicators has been playing a really emphatic role in making strategy whether it is national or EU planning.
Enterprises have always tried to measure and quantify their innovation activities mostly through the results of their economic process. Companies have generally considered their products as part of the innovation. That was the reason that in most cases they only and exclusively focused on the finished product. Some of them was able to realize that details of the production process must be taken into account in order to the whole innovation activity could be measured.
That is why I find it important to examine of what the innovativity of enterprises is made of, and in which way they can be measured.
In addition I was looking for the answer to the questions that how much the measuring method allows you to compare enterprises for further examination.The development of measurement methods is an essential moment of the article. As it is compiled for me the most important aspect of innovation, according to the statistical document, the Oslo manual guides you through the measurement methods and operational processes They play a very important role in proving my hypothesis. Overall, our country’s innovation results show those areas where we have high endowments, and also those where are the weaknesses.
Of course, systems and tools defined by the governing authorities of national economies will have the main role but the activity of the European Union will be the frame in the end, because without subsidies from the EU budget, national budget wouldn’t be enough to implement these aims.

Analysis of aerobic biological waste treatment methods especially in the case of composting
33-37Views:146In recent years the regulations of the EU unambiguously determine that the biodegradable wastes should be used in agriculture. The characteristics of the organic wastes in most cases make the direct utilization impossible, they need pre-treatment before use. One treatment solution of these wastes is composting. During composting the organic wastes lose their hazardous characteristics and we gain a final product, the compost, which can be used in agriculture as organic fertilizer. The main conditions of effective composting are the follow and understand of the degradation process. During our research we examined different measuring methods (gas concentration and reflectance measurements, temperature mapping) that makes a cost and time effective possibility to directly analyze the degradation.

Acquisition practice prior to commercial use in the European Union
153-158Views:76The target of 3% of GDP spent on R&D by the Lisbon priorities seems to be still far away from the reality in some European countries and at EU level as well. The economic crisis determined the priorities and it makes more complicated to dedicate more budget on Research and Development. New methods, new measures are needed in the European Union. Measures that supporting the demand side of the innovation and generates market-pull affects. The Europe 2020 Innovation Union Flagship Initiative dedicates a special role to precommercial procurement for the upcoming 10 years. Nowadays, there are more and more European countries running pilot projects adapting the American SBIR (Small Business Innovation Research) programme.

Presentation of sales price reserves for live lamb
37-45Views:89Although sheep breeding in Hungary is grounded in strong traditions, its activities only comprise 1% of the total production value generated from agriculture, and 2% of that for animal-based products. The most significant portion of incomes earned in the Hungarian sheep sector has, for years now, stemmed from the sale of live animals. The sector is decidedly export-oriented, as the domestic demand for its main product, i.e. lamb meat, and is minimal, equaling some 20-30dkg per person per year. Part of the sold animals is sold to market as dairy sheep, while the greater
part is sold in the category of lamb carcasses. For this reason, the average weight of slaughter sheep has lied between 19-22 kg for years now. The target markets for live lamb sales are predominately Italy and Greece. In Greece, movement on this market has shown an upward tendency in recent years; noteworthy are also sales to Austria, Holland, Bosnia-Herzegovina and Poland. In 2003, we exported sheep meat in the form of carcasses to Italy, as well as to Germany, and of these exports, 94% went to Italy, while the remaining 6% went to Germany.
Among sheep products, only the trade balance for live animal sales is positive. But even for such producers, only those who are specialized in intensive breeding and those sheep farms “targeting” meat production can obtain earnings. Specialized literature on the sector argues that the quality of Hungarian lamb has diminished dramatically and is beginning to lose its market position. If Hungarian lamb does not meet market expectations, then it will only be bought from producers at lower prices.
My research focuses on those factors which influence price. I separately discuss the question of quality, as one of the most important decisive factors on price. Within this discussion, I describe the market expectations which actually have an effect on the acceptance of live animals for sale on commission. In practice, after the problems of quality, the next most important question is that of when sale is made. In the course of my research, I studied the development of averages for sales on commission of live lambs using statistical methods. The most important problem of this sector is the hierarchical system used in sales: this is the topic hich neither the producer, nor the buyer, wish to discuss, not even with each other. On the basis of the information at my disposal, I outlined the levels of traders and individual levels used to arrive at commission prices. Finally, I examined the components of the production value of live lamb sales. The results I obtained quantified the key role of the prices and the yield, as well as the factors influencing income. -
Genetic diversity study of Hungarian honey bee (Apis mellifera L.) colonies – Previous announcement
61-64Views:162In Hungary, the Apismelliferacarnica is the native breed which is the only recognised and breedable honey bee in the country. It is assumed that there are a number of non-native and hybrid honey bee breeds in Hungary. The microsatellite and mitochondrial DNA surveys applied here will be utilised to easily and accurately identify the various sprads, and open up new ways in the research of honey bees. The isolation of the genomial DNS from 5 to 7 day old larvae samples was successfully carried out. In the future the plan is to carry out the measure with microsatellite markers. As an initial step the optimal annealing temperature was identified. In the mitochondrial DNA survey the COI-COII mytochonrial regional primer due to its low anneling temperature cannot be used with any normal sequencing methods. By using these method the aim of this research is the measurement of genetic variance.

Contributions to the 2014 and 2015 flight pattern and damages of Carpomyia schineri Loew.
96-99Views:133The fly Carpomyia schineri Loew is a pest of the berries of the feral Rosa canina group but is can also be found in the berries of grown rose cultivars. The larva damages the flesh of the berry, several larvae can develop inside a single berry. It can decrease the quantity and ascorbic acid content of the tea and jam, which are important human ascorbic acid sources during winter. At the same time in trapping experiments the adult can be confounded with adults of the walnut husk fly (Rhagoletis completa Cresson). In collections of berries at several sites in Hungary damage levels ranged from 0.88% to 65.08 %. Based on these damage levels we had the impression that the yellow sticky traps CSALOMON® PALz or PALs baited with the synthetic Rhagoletis lure caught moderate numbers of adults and were not satisfactory for detection, consequently improving trapping methods is necessary in the future.

Spectral analysis of stress symptoms caused by apple powdery mildew (Podosphaera leucotricha
83-88Views:187An orchard can be examined on the basis of spectral data, using methods with which the reflected radiation can be divided into a large number of (several hundreds) small spectral channel (some nm). Calculated on the basis of such hyperspectral data from different index numbers the water supply of foliage conditions can be well characterized.
The research site is an intensive apple orchard, which located in University of Debrecen, Agricultural Sciences Centre, Farm and Regional Research Institute at Pallag. During my experiments the preliminary evaluation of spectral, non-invasive measurement method are carried out for detecting stress symptoms caused by Podosphaera leucotricha.
Based on the results narrow band greenness indices (NDVI705, mNDVI705, mSR705 and REP) can be used for determination of diseased canopy and for the detection of stress symptoms of Podosphaera leucotricha,. These statements can be utilized in precision plant protection systems, since it can be a basis for such integrated active sensors with LED or laser light source, measuring reflectance at the certain spectral range, which can facilitate real time status assessment of orchards and can control precision fungicide utilization.

The use of MFA indicators in the characterization of the settlement sustainability
107-116Views:76One of the key sustainability challenges for the coming decades will be to improve the management of natural resources in order to reduce current levels of anthropogenic environmental pressure and respect the biological and physical limits and the carrying capacity of the planet. The first step towards meeting this challenge is an enhancement of the understanding of the material basis of our society. In the past 15 years, scientists in several research institutes have created a fast growing field of research, a new family of different methods, named material flow analysis (MFA). These instruments have an increasing policy relevance: international organizations (UN, EU, OECD) have encouraged member states to establish MFA accounting in their statistical programmes and urged governments and economic actors to use these tools. In this paper I present selected examples to reveal how the MFA approach and derived material flow indicators can be used for the evaluation of sustainability policies at municipality level.

Examination of the vegetative and generative accomplishment of new apple varieties
29-34Views:120Our research focuses on apple varieties, what are planted expansively in the development apple orchards of Western-Europe, but about the production characteristics of these varieties we don't have or just few practical experiences in Hungary. These varieties can be described with regular and high yields, aesthetic and alluring appearance in their origin places, what ensure profitable producing for the growers. In our climate what tends to be often extreme (hard cold winters, late spring frosts, summer drought, heat stress) these varieties may behave differently, so before the substantial planting it is expedient to carry out variety evaluations to avoid the later failures. The place of our experimental is located in the Nyírség, what presents adequately the ecological conditions of the surrounding areas, so the gained results can be easily adapted in the biggest apple production site of Hungary. Regarding the vegetative and the generative parameters of the 14 examined varieties ('Schniga', 'Jugala', 'Fendeca', 'Galaval', 'Fengal', 'Red Cap', 'Early Red One', 'Jeromine', 'Crimson Crisp', 'Red Topaz', 'Red Jonaprince', 'Red Idared', 'Fuji SW', club variety) we found significant differences, which is the result of the genetically coded characteristics of the varieties, the effects of the vintage, the different training methods and the correlations of these factors.

The managerial aspect of the police’s organizational development
57-62Views:171During 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.
