Hungary’s employment policy from the point of view joining the European Union
189-197Views:139What is a place of work? Is it a commitment to work, or continuous pressure under work, or hunting for income? This article is a brief review about the main milestones of the employment history of the European Union and Hungary. In 1989, the Social Charta about the social principles of employee was issued. In 1997 the employment policy became the part of the acquis communautaire. Finally, in 1998, the European
Employment Strategy was developed, which contains the community employment guidelines. In the year of millennium, the new long term concept of the EU, the Lisbon Strategy was approved. In this document the EU was targeted as the most dynamic and competitive knowledge-based economy in the World till 2010. The Tens joint to the EU in 2004, and a bit later it became clear, that the EU is light-armed against some of the world economy challenges. As a consequence, many objectives of the Strategy could not be reached. Recently member states of the EU have to develop the national action plan for employment year by year. The hungarian plans were developed as well, but the wrong labour market’s parameters haven’t been changed since 2004. -
History of origin and development of replacement of plants crop rotations is in world agriculture
53-56Views:295In practice of world agriculture a long ago the known problem of decline of harvests of agricultural cultures at their permanent growing, scientific explanation of this phenomenon became possible only with appearance of natural sciences. At first the declines of harvests bound to the toxic action of root excretions cultures on her repeated sowing, with development of humus theory of feed of plants of diminishing of harvests at the permanent sowing began to explain impoverishment of soil on a humus.
During a few centuries the known farmers development the looks in relation to forming of scientific bases of construction of replacement of plants crop rotations in the world systems of agriculture, set history of their development and improvement. The analysis of influence of possibility of optimal satiation of replacement of plants crop rotations is conducted by agricultural cultures on the level of fertility of soil, water and nourishing modes and their productivity. For the terms of the insufficient moistening a positive action is marked black pair on the improvement of the water mode of soil in crop rotations.
In historiography the problem of introduction and mastering of replacement of plants crop rotations for the decision of scientific and practical tasks of agricultural production is represented in many-sided aspects, worked out and the recommended replacement of plants crop rotations that are base on zonal principle of development of world agriculture that passed the protracted term of test and counted on various specialization of economies. But for today development of scientific and technical progress requires intensification of agricultural production with the use of intensive crop rotations and growing of high-performance cultures.
Hereupon there was a necessity of realization of analysis of the systems of historical value of scientifically-practical knowledge about development and improvement of replacement of plants crop rotations, as it gives an opportunity to work out to recommending a production with the use of the most effective elements of the past on modern agrarian business and allows to forecast them on the future.

Realisation of customer focus from quality and forage safety aspects in the Hungarian mixed feed production
35-38Views:181Customer focus is one of the main principles of Total Quality Management, and it is inevitable for long term, mutually successful vendorcustomer partnerships. The strictly controlled quality management systems of animal feed industry ensure that product quality meets the expectations of all parties involved and, indirectly the reliability of human food raw materials. Meanwhile, the participants of agricultural production are variably quality conscious, so feed manufacturers support their supply chain and also their customers with professional background and they play a key role in safe food chains from farm to fork.

The managerial aspect of the police’s organizational development
57-62Views:261During 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.

The effect of long-term fertilization on the 0.01 M CaCl2 extractable nutrient content of a meadow soil
73-79Views:178During my research, I studied the 0.01 M CaCl2 extractable NO3--N, NH4+-N, Norg, P and K contents of the soil samples originated from a long term fertilisation trial in the experimental site Hajdúböszörmény. Relationships among the soil nutrient contents, the agronomic nutrient balances of the 2009 year, and fertilization were studied.
From the results of the study it was concluded as follows:
– Fertilization significantly increased the CaCl2 extractable NO3--N, NH4+-N, and K contents of soil.
– Norg fraction increased as a function of the increasing yield. Hence, it can be assumed that the greater the produced yield, the more the stubble and root residues remain on the arable land. These organic residues can result significant increase in the Norg content of soils.
– The CaCl2 extractable P and K contents were compared with the calculated P and K limit values. According to these, the experimental soil has a good phosphorus and lower potassium supply capacity. These results are in accordance with the results of the conventional Hungarian fertilization recommendation system.
– It can be stated that the 0.01 M CaCl2 is able to determine not just inorganic N forms but Norg fraction as well that characterize the easily mineralizable nitrogen reserves. The results proved that AL-P and -K (ammonium lactate acetic acid, traditional Hungarian extractant) are in good agreement with the P and K reserves, but it is important from the aspect of environmental protection and plant nutrition to measure the easily soluble and exchangeable K-, and P-contents of soil. 0.01 M CaCl2 method is recommended for this. -
Evaluation some important microbiological parameters of the carbon cycle in chernozem soils profiles
33-39Views:342Some chemical and microbiological properties of the carbon cycle were investigated in three chernozem soil profiles. The soil profiles originated from a long term fertilization experiment (potato) of the University of Debrecen, Látókép, Kryvyi Rig Botanic Garden (grassland) and a large-scale farm (sunflower) of Ukraine. The results of the organic C-content, total number of bacteria, microscopical fungi, cellulose decomposing bacteria, CO2-production, microbial biomass carbon and saccharase and dehydrogenase activities were compared and evaluated with the help of correlation analyses. Close correlation was found between the organic carbon content and the number of microscopical fungi,, saccharase and dehydrogenase enzymes’ activities, as well as close correlation was found between the dehydrogenase activity and microbial biomass-C and saccharase activity.

Evaluation of Lipizzaner mares’ fertility data in 10 Hungarian stud farms
23-26Views:4Despite numerous studies on the genetic background and performance traits of the Lipizzan breed, fertility characteristics of Hungarian Lipizzan mares have not been systematically examined. This study evaluates the reproductive performance of 220 Lipizzaner mares from 10 Hungarian stud farms, born during the period of 1981 to 2019, using breeding records from 1998 to 2022. The mares were grouped into 25 mare families and 24 birth cohorts. Data on successful pregnancies and foalings were analyzed with respect to age, family affiliation, and breeding year. Results show that mares aged 8–12 years had the highest fertility rates, while a gradual decline was observed after 15 years. Breeding activity increased markedly after 2011, peaking in 2022 with the highest number of matings and foals born. Fertility varied considerably among mare families: some achieved consistently high reproductive success, while others showed low or zero foaling rates despite repeated matings. Hungarian mare families generally produced better fertility results, whereas Fogaras families displayed greater heterogeneity. The study emphasizes the importance of monitoring reproductive efficiency in small mare families, as unfavorable fertility trends may jeopardize their long-term viability. These findings contribute to improving breeding strategies and ensuring the preservation of genetic diversity in the Hungarian Lipizzaner population.

The role of Debrecen maize hybrids in competitive production
19-21Views:135I examined the effects of plant density and fertilisation on the yield of the maize hybrid Debreceni 377 SC, developed by the Agrárgazdaság Ltd., using the 3 year data sequence of a long term experiment set up at the Látókép experimental station of DU Center for Agricultural Sciences in years with average precipitation supply.
Based on the evaluation of my research results, I found that the application of higher plant densities was more favourable in years with average or higher than average precipitation supply. During the examination of fertilisation effects, it was verified that surplus yield was realised in most cases where smaller fertilisation dosage, 120 kg per hectare active substance was applied. -
Development alternatives of rural economy
187-191Views:159Environmental, natural, social and economic processes undergoing both in Europe and in the world predict such a 21st century that is characterised by increasing resource-crisis from both economic and ecological aspects. Therefore, it is very important for Hungary to see what happens to its natural resources, epecially to its agricultural land, water reserves as well as the biodiversity of the local unique flora and fauna. One of the most significant issues of the rural areas of Hungary is whether we can preserve the natural habitats and the various biodiversity of the related species, the favourable biological background of agriculture. In addition, whether we are able to provide high quality food for the country as well as for the broader reagion, whether we are able to produce energy from the resources available as well as to provide sufficient opportunities for the population to live and work. These can be considered as the most significant issuesof the coming decades which determine the strategy of the Hungarian rural economies in long term.

The effect of genotype and the location of sampling on the mineral content of wool
157-160Views:536Mineral supplementation is very important in high producing farm animals. The estimation of exact mineral intake is very difficult in forage eating animals, like sheep. Accessing of long term mineral status seems to be possible using wool mineral analysis. However several factors can affect the results. Therefore, the aim of this study was to test the effect of breed and sampling location on the mineral content of sheep wool. 20 Dorper and 20 Tsigai sheep were chosen from the same farm. Samples were obtained from 3 locations (withers, side and quarter) and tested for 8 elements: Ca, Mg, Na, Co, Cu, P, S, Se , Zn. The samples were cleaned with ethyl alcohol from organic contamination, then after adding nitric acid were mineral analized using ultrasonic cleaning unit. The samples were analysed with ICP-OES (Perkin-Elmer, Optima 3300 DV). Statistical analyses were carried out by GLM procedure of SAS statistical analyses software. Differences between means were checked with Tukey-test. Significant breed differences were detected in the case of Mg, Na, S, Se in spite of the same feeding regime. The wool mineral content were within the reference range. The sampling location had no effect on the mineral content of wool.

Soil moisture sensors for sustainable water management in field crop production: A review of advances and application challenges
41-54Views:19Efficient water management is essential for sustainable production of field crops amid climate change, population growth, and water scarcity. Traditional irrigation practices often lead to water use inefficiency, which harms soil health and reduces yields. To address this, reviewing previous studies on soil moisture sensors provides important context and guidance. Literature from Scopus, Google Scholar, and WoS (2019–2025) on soil moisture sensors for sustainable water management in field crops was screened. Out of 244 retrieved publications, 79 met the inclusion criteria with a focus on sensor technologies, applications, advances, and challenges, analysed thematically for research gaps and insights. Based on the findings, soil moisture sensors boost water management, improve yields of field crops, and support sustainable agriculture. However, hindrances related to high costs, lack of awareness, technical complexity, calibration needs, energy challenges, data interpretation difficulties, and compatibility problems hinder effective soil moisture sensor results. Integrating soil moisture sensors with decision-support tools optimises water use and protects soil health to promote long-term productivity under climate variability. Future research should strategise on the development of low-cost, reliable soil moisture sensors with technology subsidies, training, policy support, durability, integration, and simple data to empower farmers to adopt precision water management.

The irrigation influence under the soil, microclimate and plants in maize from Crişurilor Plain
180-186Views:214The paper is based on the researches carried out in the long term trial placed on the preluvosoil from Oradea in 1976, for establishing
the soil water balance. In the irrigated variant the soil moisture was determined 10 to 10 days for maintaining the soil water reserve on
irrigation depth (0 – 50 cm for wheat and bean, 0 – 75cm for maize, sunflower, soybean, sugarbeet, potato and alfalfa 1st year and 0 – 100
cm for alfalfa 2nd year) between easily available water content and field capacity. Thus, an average irrigation rate of 2560 m³/ha was used
in the 9 experimental crops. The average of the annual rainfall for the 1976 – 2008 period was of 625.0 mm. The technologies used were
correlated with the needes of the crops, such as melioration crop rotation, chemical fertilizers in accordance with the chemical export on the
yield, manure (40 t/ha) was used in potato and sugarbeet. After 33 years of the irrigation use the soil structure degree (38.62%) did not
decrease when compared to the unirrigated maize – wheat crop rotation (37.01%). Bulk density, total porosity, penetration resistance and
hydraulic conductivity have worse values than the ones in the unirrigated variant. The humus content is very close to the humus content
determined in 1976, the phosphorus and the potassium content increased very much in comparison with the initial content (117 ppm vs 22.0
ppm); (180.0 ppm vs 102 ppm). The use of the adequate fertilization system and of the irrigation water with a good qaulity did not determine
a decrease of the pH value of the soil. The irrigation determined the improve of the microclimate conditions, the increase of the plant water
consumption, yield gains very significant statistically and higher protein content of the maize grains. -
Effects of cultivation methods on some soil biological parameters of a meadow chernozem soil (Vertisols)
61-66Views:151The effect of extended drought conditions on soil, the unfavourable cultivation technologies and the application of chemicals have been enhancing the processes of physical and biological soil degradation, so the fertility of soil is gradually declining.
The effects of two cultivation methods – traditional ploughing (TP) and conservation tillage (CT) – on the biological activity of a meadow
chernozem soil were examined in a long term experiment. Different parameters of the biological activity of soil were determined. These are
the numbers of total bacteria, microscopic fungi, aerobic cellulose decomposing bacteria, as well as the activities of some important soil
enzymes and CO2 production.
Conservation tillage seemed to be a more favourable cultivation method for the majority of microorganisms, the activities of urease and
dehydrogenase enzymes and CO2 production, compared to the traditional ploughing system. These parameters increased significantly,
especially in the upper layer of conservation tillage plots. Concerning the plant cultures, the majority of microbiological parameters were
higher in the soil of vetch (Vicia sativa L.) depending on the cultivation methods, so involving the pulses to the crop-rotation seems to be
very important in this soil type.
According to the ninth year’s results, the importance of conservation tillage as a means of protecting the soil biological activity in meadow
chernozem (Vertisols) can be established; it was proven by microbiological investigations. -
Energy crops on less favoured (alkaline) soil
115-118Views:224The reduction in fossil energy and row material sources induces growing demand for renewable resources. The growing demand for herbal raw materials has land use impacts as well. One way to reduce the conflict between the food and energy crops can be the utilization of less favored areas by growing energy crops. Among the potentially available areas for this purpose the salt affected soils (SAS) occupy a significant territories. SAS with structural B-horizon (meadow solonetz soils) represent the most wide spread group of SAS in Hungary. About half of these soils have been reclaimed and used as arable land and the remaining 50% are used as grassland. Sweet sorghum production for manufacturing of alcohol production was investigated in a long term amelioration and fertilization experiment on a salt affected soil (meadow solonetz). By means of regression analyzes the effect of sodium content of the soil and increasing mineral fertilizer doses were studied. According to the multiple regression analysis only the effect of nitrogen fertilizer was significant. On the solonetz type salt affected soil the effect of water soluble salt content of the soil was not significant, but there was a closer correlation between the ammonium-lactate sodium content and the yield of sweet sorghum. The maximum green mass was 45–50 t ha-1, in the case of low Na content and high level of nitrogen fertilization.
In order to quantify the potential yield of natural grass vegetation the relationship between the soil forming processes and the grass vegetation
was investigated. Beyond the different forms of Na-accumulation, the spatial pattern (mosaic-like characteristic) is also an inseparable feature of salt affected soils. The difference in the water regime, caused by the micro-relief is the main cause of variability. The run-on water keeps the deeper parts of the catena position wet longer. The wet situation causes more intensive leaching. In the low-laying parts of salt affected soils species preferring wet situations (mainly Alopecurus pratensis) are in majority. On the higher parts of the micro-relief species tolerating dry situations (mainly Festuca pseudovina) are dominant. The yearly grass production of low laying areas can be 4–7 t ha-1 but because of prolonged wet conditions the grass is not grazed and mowing can only be in old state. This old grass is not proper for feeding, but it may be suitable as energy plant. -
Impact of fertilization on production capacity and reaction to fertilization in maize hybrids
42-46Views:126New varieties and fertilization have significantly increased yields of maize in recent decades. It has to be taken into account however that the interactions and the balanced combination of cropping factors (ecological, biological and agrotechnical) are the main factors which determine yields. Weather conditions were rather unfavourable during the last decade. Extreme weather conditions occurred due to global warming; 6 of 10 years were plagued by drought. Consequently yields increased from 10-20% to 30-50%. In view of varieties the situation is advantageous, maybe the supply of hybrids is too high, nevertheless those hybrids need to be selected which are particularly well adjusted to the ecological conditions. Many technologies can be applied which vary according to intensity, but the balanced combination of cropping factors should be secured on the basis of the hybrid’s intensity. Among agrotechnical factors the compensation of nutrients and technological conditions were inadequate. These days farmers only use nitrogenous fertilizers consequently they significantly decrease the easily available P and K content of the soil which in long term leads to the deterioration of the soil’s productivity. The technological background is therefore important, because sufficient yields can only be expected if agrotechnical operations are carried out in the right time and quality.

Relationships of the sport and the life quality in the University of Debrecen
87-96Views:232In the sport- life of the University of Debrecen there has been a demand formulated on the making of a comprehensive, long-term development plan, which obviously incorporates all
fields of sport. This document guides the way for people in the sport- life of the university how they could organise their activities connected with sport on a calculable, predictable level.
Necessarily, the preliminary collection of professional informations has been a basic requirement for the establishment of this document.
The program provides foreseeable instructions to the organisation of sport pursuits both for sport people in the university, and members of the sport spehere in a wider sense. It
offers a cohesive solution for all kinds of tasks defined with the sport life, and also gives a guidance for the various ways of realisations of these challenges. Thus it can answer such questions as for example how the university can conduce the initation of conditions for the healthy living through spare time sporting, how it can participate in the financing of contest sport with the contributing project of reinforcement training and how the university can support the sport life of handicapped people. The project also contributes to the cultivation of the sport traditions of the university by bankrolling not only the official university sport
life but also the leisure time sporting of the students.
On the basis of rethinking the situation of sport at the university with its future possibilities the program paraphrases the tasks of the university in the sport life, the long term aims of
university sport politics with its operative aims that should be performed and also the possible steps which lead to these purposes.
The target of the project is to turn the University of Debrcen in every field into a “Sporting University”. It means, that beyond the development of quality sport and outstanding contest sport a much wider range of university people should be included in sporting in order to utilize all the advantages of sport. With this the physical culture could become not only a substantial form of spending our free time, but with getting one of our natural everyday activities it can also become our lifestyle.
Sporting prominently contributes to both the university students’s and the whole society’s mental and physical wellfare, and it also helps to improve our helthstate on various fields of life:
with its special functions it is a means for establishing a healthy nation, for promoting common relationships, for nourishing the economic activity of people and also for strengthening the national values and one’s self-esteem through providing equal opportunities.
The prosperousity of contest sport at the university and the maintaining and protesing of its efficiency fortifies our selfregard, as it is able to hold appropriate sportsmen up as examples
to both present and future universtity students, and also offers exacting ways of entertainment. Besides all these the advataged purpose of the project is to find and delibaretaly include those
necessary mechanisms which are needed for the working of the sport market. -
Desert greens: Unveiling the antioxidant power and health benefits of Qatar's locally grown leafy vegetables
11-17Views:524The long-term consumption of diets rich in plant polyphenols has a high potential to reduce the risk of chronic diseases such as cancer, cardiovascular disease, and diabetes. This study focuses on the phenolic and antioxidant properties of eight green leafy vegetables, red spinach, green spinach, water spinach, chives, rocca, Swiss chard, jute mallow, and purslane, commonly cultivated in Qatar. Antioxidant capacity (AC) was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method. The total phenolic content (TPC) of the samples was quantified using the Folin-Ciocalteu assay. Among all the vegetables, results indicated significant differences among all examined values at level of 5% Jute Mallow exhibited the highest phenolic content at 205.39±11.50 mg GA/100g, followed by Green Spinach at 189.58±10.56 mg GA/100g and Red Spinach at 185.15±2.93 mg GA/100g. Swiss chard exhibited the highest antioxidant activity of 89.26%. This study provides valuable data on these vegetables to positively affect the health and well-being of the population. Intensifying further future investigation to embrace a wider phytochemical profile (e.g., flavonoids, carotenoids, vitamin C), varied antioxidant assays (e.g., FRAP, ABTS), and bioavailability tests would expand the understanding of the studied leafy vegetables health benefits.

Urgent agricultural issues of soil protection
169-172Views:221The primary aim of this study is to draw attention to the importance of legal problems of soil protection. The basis for my study is the ombudsman’s 2016 principle of soil protection. This resolution summarizes the most pressing soil protection measures in 15 points that need to be taken as soon as possible to preserve soil resources. To narrow the wide range of topics, I will examine three points: (1) preservation of soil resources, (2) soil sealing, (3) brownfield instead of greenfield. Hungary is in a special position concerning this most ancient natural resource, as only 11% of all the land covered area of Earth consists of soil, the EU average is less than 30%, while in Hungary it is more than 60%. Despite the existing protective legal requirements, soil degradation is a constant issue. The persistence of population growth spells the need for more arable land, but as a result of the stressful impacts caused by people we are running out of useable topsoil.
Assessing both the short and long term process of land reclamation, it can be stated that more and more farmland becomes permanently and imperviously covered for other purposes each year, and as the arable land area decreases, the impervious surface area grows despite all respective decisions, regulations and prohibitions.
