Regional Development Differences in Hungary and the Northern-Great Plain Region
Published March 4, 2005
62-71

The most important endeavour of European Union’s regional policy is to moderate disparities. An emphasised strategic objective of member states, based on the principle of solidarity, fairness and justice, is to develop regions and almost forty percent of the common budget is devoted to achieving this objective.
Hungary, as a full EU member... state, will get a new chance for underdeveloped regions, especially for the Eastern-Hungarian as well as the North Hungarian and North Plain Region.
The differences in development among the regions are significantly influenced by the economic characteristics of the specific region, quality and quantity of human resources, accessability of the region and other factors influencing local quality of life beside natural conditions.
The new spatial structure was formed by change of regime, processes of the nineties, primarily the economic renewal based on foreign capital investments and the crisis phenomena in parallel with these. The economic, political and social consequences of the transformation significantly changed spatial structure and increased disparities. New disparities formed which were further aggravated as a consequence due to the formation of the eastern-western slope and local crisis zones. As a result of the outstanding development of the capital, the long term differentiation of regional development differences can also be detected when examining the regional distribution of Hungarian gross domestic product. The collapse of heavy industry and agricultural mass production based on the eastern markets primarily affected the north-east counties in the eastern part of the country.
Strengthening regional competitiveness is of key importance for the region, which requires the application of consistent development policy. The most important is economic development which, if it operates well, also infers the possibility of establishing welfare infrastructures. Drawing in external sources to ease the significant lack of capital is important for the processing industry and the development of supplier networks. Agricultural development also plays an important role in transforming economic structure, since the characteristics of the region, its traditions and long term competitive advantages are favourable, therefore it is going to represent a higher ratio within the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting market accession, quality agricultural production and stimulating producer-retailer cooperation. The development of transportation and informatics infrastructure as well as human resource development plays a significantly important role in the development of the region.
In conclusion, the implementation of such a consistent regional development policy is required in the future, based on the strengths of the region, that serves the most efficient utilisation of regional development funds through the implementation of regional policy principles and prevents the irreversible decay of the region while promoting rapid development.

Renewal of the city network in Szabolcs-Szatmár-Bereg country after the political restructuring
Published May 16, 2012
21-25

After World War I., but especially from the second half of the 20th century the public policy development is determinative in urban development. The urban and the country planning appears under the auspices of the regional development policy between the world wars. After 1945 the primary goal in economic and development policy was the socialist... industrialization, with a priority on cities. In this period the driving force in urban development primarily were the industrial installations. As a result, economic and social structure was transformed. It is a fact, that planned economy gave a huge impulse to city network, which determine the trend of cities up to this day. After the regime change, as an effect of escalation of regional differences and as a result of economic processes the urban development took new directions. The state intervention changed, and the principles of decentralization prevailed in resource allocation. The private and non-profit sector appears in urban development, the governments gain more important roles. These three sectors became the movers of local development. To recognize the main trends of urban development in Szabolcs-Szatmár-Bereg County, the local area development funds were examined in a special way in a given period. This study will show, the main tendencies of the consumption of decentralized regional development funds between 1996–2008, in the cities of Szabolcs-Szatmár-Bereg County. This study also gives an answer for which factors convert the renewal of city network of Szabolcs-Szatmár-Bereg County after the regime change.

Differences in Regional Development in the Northern Great Plain Region
Published December 6, 2005
170-180

An important ambition of EU regional politics is the reduction of disparities. An important strategical objective of the Commission is to terminate underdevelopment and to ensure the development of the regions based on the principles of solidarity, equity and justice. The commission has dedicated forty percent of its common budget to achieve th...ese goals. The differences in development are significantly influenced by the economic characteristics of the specific region, the quality and quantity of human resources, the accessibility of the region and factors influencing local quality of life.
The new spatial structure has been formed by the processes of the change of regime, the events of nineties and the economic renewal based onforeign capital investments parallel with crisis phenomenon. The economic, political and social consequences of the transformation have significantly transformed spatial structure and increased disparities. New disparities have formed, which strengthened due to the formation of east-west slopes and local crisis zones. The outstanding improvement of the capital resulted in great regional development differences, which can be detected when examining regional distribution of gross domestic product. The Eastern part of the country was most heavily affected by the collapse of heavy industry and agricultural mass production based on the Eastern markets.
It is of key importance for the region to strengthen regional competitiveness, which requires the application of consistent development-politics. Economic development is the most important, which can also draw the possibility of establishing welfare infrastructures. It is important to develop the processing industry, the supply networks and to ease the lack of capital it is also important to involve foreign capital. Developing agriculture plays an important role in transforming the structure of the economy. Since the conditions of the region, its traditions and long-term competitive advantages are favorable, thus can represent a greater ratio in the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting marketing, quality agricultural development and producer-retail cooperation. It is also highly important to promote development in transportation and informatics infrastructure and human resources.
In the future – based on the strength of the region – it is necessary to achieve such a consistent regional development politics, which by validating the principles of regional politics, serves the interest of utilizing regional development supports most efficiently and prevents the irreversible underdevelopment of the region and promotes fast development.

Examination of the sub-regions in the North Great Plain Region
Published July 16, 2007
158-163

Before Hungary joined the European Union – in order to gain access to the sources of Structural Funds and to create the expected regional information service – a build up of five-level territorial system was indispensable. Both in the EU and in Hungary, there are significant differences among regions. The aim of regional policy is to reduce... differences regarding development and living standards, in order to guarantee a reasonable living standard and income for every region’s inhabitants in the EU.
In Hungary, during the last decade, the effects of regional difference grew. While the advantage of the leading capital and its agglomeration and the eastern and western parts of Transdanubia was growing, meanwhile the most undeveloped areas' rates of development remained under the mean. The underdeveloped areas are in the northeastern part and in Southern Transdanubia. The developmental differences lead to such great social asymmetries, that these simply beg for remedying.
In this study, I would like to present the sub-regions of the North Great Plain Region and uncover the possible reasons of the developmental differences.

Development of the reproductive tract of immature gilts
Published November 20, 2011
165-166

Mechanisms of regulation of litter size in pigs are complex and depend on many factors, including genetic regulation and also physiological and anatomical development of the reproductive tract in gilts. Improvement of growth rate in present breed pigs raises the question as to whether, with the development of the reproductive tract, sexual matu...rity would also be attained.
The aim of the study was to assess the morphometric traits of reproductive tracts taken from gilts slaughtered at 100 kg body weight, i. e., just when they may become actively sexual mature.
This study was concluded on 80 prepubertal gilts of the Polish Landrace (PL) breed tested at the Pig Program Testing Station. The animals were kept in individual pens with control feeding and standard management. They were slaughtered after attaining 100 kg body weight. Immediately after slaughter, the reproductive tract was removed and carefully assessed. The morphometric estimation of the reproductive tract involved the
measurement of uterus weight with ligament, vagina-cervix length, uterine horns and oviducts length, ovaries weight, height and width. Uterus volume capacity was also determined, based on volumetric method of Kwaśnicki’s (1951) with own modification.
All pigs were divided into three groups in respect to age at slaughter: A – below 160 days (n=38), B – from 160 to 180 days (n=28) and C – above 180 days of age (n=14). The results were elaborated statistically computing the arithmetic means (x) for every traits and standard deviations (s). One-way analysis of variance ANOVA was performed. The significance of differences between age groups was estimated using Duncan’s test.
Calculations were performed with STATISTICA 8PL Software.
Obtained results are presented in the tables below. The most pronounced differences in the development of the reproductive tract are dependent on the age of gilts concerning only the uterus weight (P≤0.01) and uterus vagina-cervix length (P≤0.05). Gilts at age 160-180 days attained the full stage of reproductive tract development. Differences between the compared age groups of gilts dealing with the other morphometric traits
and ovary characteristics were statistically not significant.

Development Level of Settlements of the Statistical Subregion of Nagykálló
Published September 22, 2004
54-59

I have attempted to develop methods and applications for indices used to evaulate the development of settlements. At first stage the complex index applied by the Central Statistical Office (CSO) was differentiated according to economic, ecological and social aspects, and at the same time the system of indices was extended. As a result of these ...the ranking list of the exemined settlements has changed compared to the ranking based on the complex index applied by the CSO. There are significant differences particulary in the evaulation of the ecological development, however, in same cases ranking of economic and social development of settlements is also different. These analyses demonstrate that by using more indices the evaluation of development of settlement would be more objective, and by classifying according to the three functions of the country the countradictions would be more visible.

This paper aims to make a settlement and micro region-level analysis in case of one of Hungary’s most backwater regions, the Hungarian-Ukrainian borderland. After a brief methodological and theoretical review, it creates a complex development indicator with the help of certain ratios belonging to appropriate groups. It analyzes the exceptiona...lly heterogeneous settlement-level values with applied statistics methods and tries to determine the role of population, population density, the distance from the nearest border-crossing point and the travel time from the centre of the micro region and the county. As its main findings the followings can be mentioned: there are significant development level differences in case of the „periphery of the periphery” micro regions which depend on the number of population, population density and the travel time from the centre of the micro regions.

The development of the new economy in Hungary involves a complexity of economic and social processes. The sectoral structures and territorial location of the industy and the higher education show significant inequalities. Capital city concentration, low level of research orientation and insufficient linkages with industries are the most importa...nt barriers of the development of higher education and reindustrialization. The regional and cohesion policies need strong relations between economic restructuring and higher education development. The paper focuses on demonstrating the regional differences in these fields in southern and eastern Hungarian regions.

Effect of the plant density on different maize (Zea mays L.) hybrids yields and leaf area index (LAI) values
Published March 5, 2015
51-56

We have investigated the plant number reactions of three maize hybrids of various genotypes in a small-plot field experiment. The plant numbers were 50, 70 and 90 thousand ha-1, while the row distances were 45 and 76 cm. The experiment was set on the Látókép Experimental Farm of Centre for Agricultural Sciences of the University o...f Debrecen in four replications on calcareous chernozem soil.

The assimilation area and the leaf area index have important role in development of the crop yield. The studied three different genotype maize hybrids reached its maximum leaf area index at flowering. The maximum leaf area index increased linearly with increasing plant density. The season-hybrids reached less yield and leaf area index. According to our experimental results, we have concluded that with the decrease of the row spacing, the yield increased in the average of the hybrids. The studied hybrids reached the maximum yield at 70 and 90 plants ha-1 plant density. We determined the optimal plant number that is the most favourable for the certain hybrid under the given conditions.The higher plant density was favourable at 45 cm row spacing than 76 cm. The hybrids reached the maximum grain yield at 45 cm row spacing between 76 712–84 938 plants ha-1, while the optimum plant density at 76 cm row spacing changed between 61 875–65 876 plants ha-1.

The leaf area index values between the applied plant density for the flowering period (July 1, 24), we defined a significant differences. In the archived yields were significant differences at the 45 cm row spacing between 50 and 70, 90 thousand ha-1 plant density, while the number for the 76 cm row spacing used did not cause a significant differences in the yield. There were significant differences between the examined hybrids of yields.

Spatial environment analisys of the bioenergy production and utilization
Published December 16, 2012
235-240

The backwardness of the rural areas compared to the cities poses a problem all over Europe. Rural development and the reduction of differences between the development levels of the regions have expressed roles among the programs of the European Union. Member States are even entitled to subsidisation, they just need to manage subsidies economica...lly. In Hungary, a relatively small amount of the population lives in the capital, more than 80% of Hungarians live in rural cities or villages. The opposition between the countryside and the cities is rather intensified and the symbiotic correlation would need to be restored. Many people migrate from the countryside, especially youngsters, as they have no opportunities to find any job. This phenomenon poses big risks because getting a job is usually difficult everywhere and because fitting into a new environment always involves a lot of difficulties. Also from the aspect of the national economy, migration from the rural areas to the cities is a problem. The state budget will face significant excess costs if someone moves from a village to the city. It could cause unpredictable consequences if people leave the villages, as the maintenance and development of the village living space will face a hopeless situation.
Non-renewable energies are restricted and they will not be accessible after reaching a certain limit. People’s everyday activities and the functioning of the economy presupposes the availabilty of the necessary amount of energy. In the future, solution that provide the longterm stability of energy for the world will become increasingly necessary. There is a huge potential in bioenergy, more specifically in biomass. The building of biomass plants and putting them into operation creates jobs in the rural spatial environments. A locally available resource that can help in creating the energy safety of the country and the reduction of the dependence on import. The production of energy crops or the crops whose purpose of use is energy could help in strengthening the multifunctional character of agriculture and it can represent a source of income for those living off of agriculture under the current uncertain conditions.

The effect of production area on the development of yield producing factors of maize (Zea mays L.) hybrids of different genotypes
Published February 18, 2016
67-72

Maize yield amount development is determined by the given crop year and the genotype of the applied hybrid, but beside these also by the applied agrotechnical factors, in particular by sowing technology. The development of yield amount and yield producing factors of five maize hybrids of different genotypes has been studied in a small-plot fiel...d experiment by the application of different row spacings and plant density variants. The production of the individual plants shows decreasing tendency parallel to the increasing plant density, however, this decrement is compensated by the higher number of plants per unit production area. Individual plant production is determined by the development of yield producing factors, such as the length and the diameter of cobs, just as by the thousand seed weight – that were studied in the present research work as well.

In the present research work the decreasing row spacing resulted in a yield increment of 0.67 t ha-1 (4.53%) in 2013, while in contrast in 2014 yield was decreased by 1.75 t ha-1 (14.87%). The high amount of precipitation in March was determinant in 2013: it filled up the soil water stock and balanced the negative effect of the inadequate amount and distribution of precipitation during the vegetation period for the yield. Lower extent of yield increment (0.6 t ha-1) was registered in 2014 in case of the row spacing of 76 cm than in the previous year. In case of a row spacing of 45 cm the difference between the two crop years was 3.1 t ha-1. The highest impact on the yield production factors was found in all treatment combinations in case of the applied hybrid among the three studied treatment factors. In the crop year of 2014 the effect of plant density on cob diameter and thousand seed weight could be revealed as well. In case of the cob diameter significant difference was found between the plant densities of 70 000 and 90 000 plants ha-1, just as between the populations with densities of 50 000 and 90 000 plants ha-1. In case of the thousand seed weight significant differences could be found by the application of plant densities of 70 000 and 90 000 plants ha-1. The highest values of the studied yield producing factors were measured in case of the plant densities of 50 000 and 70 000 plants ha-1; increasing the plant density to 90 000 plants ha-1 resulted in rather decreasing values.

Effect of different sources and doses of sulphur on yield, nutrient content and uptake by spring wheat
Published June 1, 2021
109-115

The objective of this study was to investigate the effect of two sulphur forms (sulphate and tiosulphate) in combination with three different N:S ratios on the yield of spring wheat and total N- and S-content and uptake by the aboveground biomass on chernozem and sandy soil. In the greenhouse experiment, the effects of two sulphur forms wer...e compared: sulphate (SO42-) and thiosulphate (S2O32-). The sulphate was applied as potassium-sulphate (K2SO4) and thiosulphate as ammonium-thiosulphate ((NH4)2S2O3). Increasing doses of both sulphur forms (24, 60, 120 kg S ha-1) were used with the same nitrogen dose (120 kg N ha-1) which caused three different N:S ratios background (1:0.2, 1:0.5, 1:1). Nitrogen was supplied in the form of monoammonium-phosphate (MAP), ammonium-nitrate and ammonium-thiosulphate. Plant samples were taken in three different development stages of spring wheat based on the BBCH scale: at the stage of BBCH 30–32 (stem elongation), BBCH 65–69 (flowering) and BBCH 89 (ripening). The total nitrogen and total sulphur content of plant at different development stages and also wheat grain were measured by Elementar Vario EL type CNS analyser. The nutrient uptake by plant and grain was calculated from the yield of spring wheat and the N and S content of plant.  The grain yield on chernozem soil ranged between 6.31 and 12.13 g/pot. All fertilised treatments significantly increased the grain yield compared to the control. The highest yield was obtained in the case of the application of 120 kg N ha-1 and 60 kg S ha-1in sulphate form. The grain yield on sandy soil varied from 2.53 to 6.62 g/pot. The fertilised treatments significantly enhanced the yield compared to the control. The highest yield was observed in the case of the application of 120 kg N ha-1 and 60 kg S ha-1 in thiosulphate form. On chernozem soil the increasing doses of sulphur (24, 60, 120 kg S ha-1) with the same N dose (120 kg N ha-1) increased the N-content of spring wheat at all development stages and in the grain. The treatments with different sulphur sources did not cause further changes in the N-content. On sandy soil in the most cases the N-content did not change significantly as a result of increasing sulphur doses. The treatments with sulphate form basically resulted higher nitrogen-content than treatments with thiosulphate form. The treatments with increasing sulphur doses resulted higher S-content on both of chernozem and sandy soil in the case of all development stage. Comparing the effect of the applied sulphur sources on the S-content it can be stated that at the stage of BBCH 30–31 and 65–69 the treatments with sulphate form resulted higher sulphur-content. At the stage of BBCH 89 there was no significant differences in S-content of grain as a result of different sulphur-sources.

13-18

In every economic sector, the enacted and expected quality of the products strongly affects its market entry and subsistence. The aim of management is success, competitiveness and subsistence that require adequate human and material resources and enough production stock. We must also notice that the quality of tools and instruments significantl...y influences work productivity. This applies to both plant production and animal husbandry.

The author researched milk production factors with methodical observation, document analysis and interviews. Data were collected with a ten-year interval, thus this assay can highlight the field, volume and sources of investments during this period and that the production stock increased in most farms and decreased in few. The data also shows the influence of investments on work productivity - there are differences between farms of equal size, so there are still ways of development.

The effect Benefit PZ biostimulant on the fruit size and yield production of apricot varieties (Prunus Armeniaca)
Published May 23, 2006
16-18

Fruit size is determined by the genetic makings of varieties the pomology and enviromental factors. The climate and the previous year’s harvested yield have a great effect on yield volume. It is not easy to harmonize the qualitative and quantitave parameters of the fruit. High yield usually causes smaller fruits.
The aim of our trials was ...to evalaute the effect of Benefit PZ biostimulant on fruit size. We examined two apricot varieties (Bergeron, Magyarkajszi C235) for the efficacy of the product. The three applications were made with 400 l/ha water with 2500 ppm. The optimal interval of application with Benefit PZ is during in the early phases of development. The size of the final fruits depends on the number of cells making up the fruits. The later application could not increase fruit size growth, there are no significant differences between the Benefit PZ sprayed and the control plots. The totally harvested fruit weight was 13.5% more on the trees of cv. Bergeron, it was caused by the higher fruit set. On the sprayed trees were 12.2% more fruit. Therefore were no differences between the average fruit weight. Fruit weights of the treated trees were 44.37 g on cv. Bergeron, 44.15 g on cv. Magyarkajszi C235 and on the no treated trees were 43.83 g as well as 45.33 g.

Effect of supplemental pig milk replacer on piglet weight gain and sow backfat thickness
Published March 24, 2015
43-47

Sow milk production is the major factor limiting pig growth to weaning. Although the milk production of the sows incremental many environmental factors affect the actual performances. The supplemental milk replacer can be an appropriate solution to ward off disparities and try to equalize the available milk quantity to the piglets according to ...their appetite, to enlarge the weight of pigs at weaning, ultimately. The aim of the present study was to investigate the effects of liquid milk supplement on weight development and litter performance of the piglets during the suckling period. Data were collected from 60 farrowings, the weight of 649 piglets in a total were measured at birth, 14 days old and at weaning (28 days), respectively. In the control group (n=319) the piglets were suckled and got prestarter feed from day 10. In the experimental group (n= 330) the piglets had got liquid milk replacer in 10.71% solution, from day 10 after birth together with suckling and prestarter feed, as well. Based on the Duncan's multiple range tests, there were no significant differences in birth weight between the control and experimental group but we found significant differences between the 14 days weight and the weaning weight, subsequently. Based on the CV% of weight the experimental group became more homogenous, in contrary to the weight of the control group at the end of suckling period. The milk supplementation can be an appropriate solution to ward off disparities and to equalize the available milk quantity to the piglets according to their appetite, to enlarge and uniform the weight of pigs at weaning, ultimately.

There are significant differences in the level of economic development and social relations between the various regions of Hungary, consequently, their competitiveness is also dissimilar. The term ’competitiveness’ has recently gained a regional meaning from various aspects. The unified interpretation of ’competitiveness’ is applicable ...to all basic units of the economy in a flexible way, and is therefore applicable on regional level as well. Regional competitiveness is measured against four economic categories: regional income per capita, work efficiency, employment rate and age composition. In addition to an overview of the region, this study will analyse the above components of regional competitiveness based on data describing the region.

The Effect of Smut Gall Tumour Infection on Iron and Zinc Uptake and Distribution in Maize Seedlings
Published December 14, 2004
27-32

The amounts of Fe, and Zn were measured in maize seedlings infected by smut gall tumour (Ustilago maydis Dc. Cda.) and in healthy seedlings five days after infection. The amount of elements was also measured under different stress intensities. Due to the infection, as a biotic stress, the amount and distribution of examined elements have been c...hanged. On the bases of the differences in the Fe distribution between the symptoms less and tumorial leaf parts, we have come to the conclusion that the infection also effects the mobilisation of Fe and Zn inside the plants. The Fe uptake was much higher in the infected plants and the tumour development also had an effect on the uptake and distribution of the examined elements. The experiments of infecting maize seedlings by monosporidial strain of crown gall tumour showed no tumour development. We found that the monosporidial strain also acts as a biotic stress and has an effect of iron and zinc distribution. We observed a slight difference in the iron and zinc contents in the roots of corn seedlings infected by different monosporidial sporidium concentrations, while the iron and zinc contents in the shoots were increased by the intensity of the infection. The roots do not form tumours. There is no difference between the roots of the infected and healthy corn seedlings. Since the Fe and Zn contents of the shoots of infected plants depend on the intensity of the infection, we have come to the conclusion that there must exist a „special” communication system regulating the transportation of the examined elements.
In the experiments with infected maize seedlings, it became necessary to get the iron chlorosis before the disease reaches the lethal phase. Although most of the iron reserves are located in the embryo, to accelerate the chlorosis, the endosperm was removed, and it was observed, that the iron chlorosis appears later in maize seedlings when the endosperm is removed. The relative chlorophyll content of the first and second leaves was measured in iron efficient and iron deficient maize seedlings at different times.
The higher IAA content of tumorial plant tissues is already known. The treatment with IAA decreases the iron concentration in the shoots and in the roots of +Fe precultured plants and increases at -Fe precultured ones. The TIBA retards the shoot-to-root transport of IAA. When the seedlings were treated simultaneously with IAA and TIBA, higher iron concentrations were observed in the shoots and in the roots of corn seedlings.
We found extremely high iron concentrations in the roots of infected seedlings and, in line with this, serious damage to the roots was observed that this can be caused by the high iron content generated free radicals. The results demonstrate that IAA has a role in the shoot to root communication.

Study on Human Resource Management in Agriculture
Published December 10, 2002
171-181

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 invest...ments, 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.

The impact of applying foliar fertilizers on the health condition of maize
Published May 20, 2020
105-109

 

The nutrient supply of plants is becoming more important in plant protection since the appropriate condition of plants can be ensured by optimal and satisfactory nutrient supply to avoid nutritional deficiency diseases. Due to the extreme weather conditions, plants are forced to face several stress factors, which lea...ds to deterioration of the plant health. The increasing occurrence of droughts poses threat to nutrient uptake through the roots since all the nutrients can be accessible to the plants only if they are in dissolved form in the soil – which is not possible in the absence of water. Therefore, the importance of foliar fertilizer is becoming a more and more significant part of the nutrient supply, because with the help of this technology the development of any nutrient deficiency can be prevented.

In this experiment, we focused on the efficiency of two different foliar fertilizers on maize.  Foliar fertilizers were applied two times, once in the stage with 8 leaves and tasseling phenophase of the maize. To verify the efficiency of the foliar fertilizers, the chlorophyll content of untreated and treated plant’s leaves was measured after each application. Moreover, the length and diameter of maize cobs, thousand kernel weight, protein, oil and starch content were also measured, and the results were compared to the untreated (control) ones. According to the results, in all aspects significant differences were observed and due to the laboratory analysis of leaves, in the case of magnesium and zinc supply the foliar fertilizers were able to prevent the development of nutrient deficiency.

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">The summarizing data collection of our study has been carried out in the scope of the FP7-REGPOT-2010-1 ’UD_AGR_REPO’ project as a part of the cooperation with the University of Lincoln. The University of Lincoln is an important partner of the project, the knowledge transfer activities that have been carried jointly with them are multilateral. One of the most important cooperation areas is the analysis of rural areas, rurality itself, determination of breakout points, exploration of alternative income sources, diversification possibilities. Some part of the work of the University of Lincoln on the field of rural development is based on the assessment and documentation global similarities and differences of rural areas. Present study also contributes to that work, it has been prepared on the request of the University of Lincoln with the aim of providing insight into the special political and economic changes/processes that took place in Hungary, and through them into the structure and operation of the unique Hungarian rural areas.

The study first positions the definition of rurality and rural areas into context on the basis of official EU and Hungarian legal classification. Then it covers the important agricultural nature of Hungary, which significantly determines the possibilities and properties of Hungarian rural areas. The further description of rural areas is completed by some historical summary, the introduction of ownership changes, detailed description of employment and income conditions and finally by the listing of breakout points of rural areas as a conclusion.

Study of some physiologic properties of different genotype sweet corn hybrids
Published July 31, 2012
105-110

The effect of nutrient-supply (control, N120+PK) and two different genotypes on the physiologic properties of sweet corn has been investigated in the crop-year of 2011 on chernozem soil in the Hajdúság region. The experiments were carried out at the Experimental Station of the University of Debrecen in Debrecen-Látókép. The experiment was ...sewn in two different sowing times: the 21st April can be considered as an early, while the 19th May as a late sowing time. The two involved hybrids were Jumbo and Enterprise. The applied plant density was 65 000 plants per hectare.
Our aim with this experiment was to study the plant production, just as the main affecting factors of its development and dynamics, like nutrient-supply and genotypes. We aimed to study and analyse the relationships between these factors and plant production. In this study following parameters were measured and calculated: photosynthetic activity, chlorophyll-content (SPAD-value), leaf area index (LAI) and leaf area duration (LAD). Regarding the analysis of photosynthetic activity values no obvious relationship between the measured values and the applied hybrids, just as nutrient-supply has been revealed. 
Analysing the SPAD-values it can be stated that the chlorophyll-content of the measured leaves showed an increasing tendency due to the nutrient-supply. The highest values have been measured in the intensive cob development phase of the early sowing time plots.
Regarding the LAI-values we have found significant differences between the fertilizer treatments in both sowing time treatments. In case of the leaf area duration values – that is derived from the LAI values – nutrient-supply has positively affected the duration of the assimilation area.

Establishing regional cultivating districts on the basis of the Kreybig practical soil mapping system
Published May 27, 2001
20-25

With the help of this report evaluating the current situation of the region, characteristics of the development in agricultural production and regional differences can be clarified. By mapping out the regional soil, land use and climatic conditions and organizing these into a geographical information system, one can easily determine which plant...s are the most ideal to cultivate in that particular region. Moreover, it is a useful tool that enables us to
establish the most favorable land use structure suited to ecological demands and also helps to determine the methods of soil protection.
During our work, we chose administrative units in Szabolcs-Szatmár-Bereg County, based on the latest aspects of regional cultivation.
Our pilot areas are: the small regions of Nyíregyháza, Nyírbátor, Nagykálló, Mátészalka and Csenger.
Using the database, we separated and uncovered the soil conditions of the pilot areas: the chemical and physical properties of the soil layer which is exploited by the roots of the plants, the humus content, the nutrient supply, the thickness of the cultivated layer and the water management conditions.
We separated the districts of regional cultivation, where the basic elements of the traditional Kreybig color systems were applied (light yellow, dark yellow, light brown, dark green, blue, pink, red, gray, greenish brown, reddish purple, light purple, dark purple, light green).
By using the data collected from the pilot areas, we compiled a map database, which is suitable to illustrate the plant cultivating characteristics of the region. We made recommendations to determine the most favorable plants to cultivate in the specific region with the given meteorological and soil conditions, as well as for the shifting of crops.
Our recommendations were also illustrated in a map with a resolution of 1:25000.
