Effect of the dry and rainy weather on the Idared and Golden Reinders apple varieties fruit quality
107-110Views:88Weather conditions have an important role in fruit production. In the last few decades, this role is increased and basically determines the
fruit quality and quantity. Despite of this statement, there is but very few information about impacts caused by weather anomalies in
Hungarian orchards. Regarding this, the relation between the external, and internal values of the Idared and Golden Reinders apple varieties,
the changing of the temperature and precipitation in a dry year (2009) as well as in a rainy year (2010) were investigated. The examined
apple varieties are grown at the same training system (rootstock, spacing, training, pruning system). The average weight, average diameter,
acid content and soluble solids were higher in 2009 than in 2010, although the precipitation was higher in 2010. Due to the many rainy days
the intensity of sunshine and the number of sunny days were less. To produce better quality it is very important the amount of the sunshine
and heat, the optimal temperature and the precipitation rate. -
The examination of human resources in the Hódmezővásárhely micro-region on the basis of human resource hierarchy
91-110Views:72In this paper, I deal with the examination of the situation and change of human resources through the human resource hierarchy. My research covers the Hódmezővásárhely micro-region, which includes four settlements, two towns (Hódmezővásárhely as the centre of the area and Mindszent) and two villages (Mártély and Székkutas). Based on population density the micro-region is qualified as a rural territory, which is underpinned by the micro-region’s market town and homestead like character.
I took the human resource system of Cloke and Park (1985) published in their book of Rural Resource Management as a basis of my examination and I pursued my research in consideration of Fehér’s (2005) researches related to rural economy. The system of human resources provided a hierarchical and logical framework for my examination. In the course of the research I made analyses along the three levels of human resources concerning the micro-region and its settlements.
During the examination of the human resources of the Hódmezővásárhely micro-region I pointed out some negative changes and situations which unfavourably influence the socio-economic processes of the territory and its settlements. All this reveal that the human resources are not only factors of the economy of the micro-region as a rural economy but at the same time they are areas to be developed. The living standard (welfare) of the people living in the area and their quality of life (well-being) depend on the development and level of the different dimensions of the human resources largely. For that very reason there is a need for coordinated development of the human resources and the related fields with respect to the cause-effect relations.
My research contributes to the better cognition of rural resources of the Hódmezővásárhely micro-region, without this a rational improvement and sustainable development of the micro-region and its settlements based on inner resources cannot be imagined. -
Evaluation of the yield and baking quality of winter wheat (Triticum aestivum L.) varieties in different cropyears
95-100Views:104We have investigated the effect of the cropyear, the genotype, the nutrient supply and their interactions on the yield and the quality parameters of three different winter wheat genotypes in three different cropyears. The most disadvantageous influence on the yield averages was caused by the moist weather of 2010, when yield results fell behind the mean of the two other examined years and the nutrient optimum was around low doses. The optimal cropyear turned out to be the ordinary 2011, the best yield results were experienced during this cropyear. Although the drier periods in 2012 decreased the yield values, the varieties could realize high yield maximum values. Considering the yield results, Genius turned out to be the best variety. In respect of the quality traits, 2010 turned out to be the best cropyear in case of all the three varieties. Despite the dry weather of the spring of 2012, the precipitation fell during flowering and ripening phases had positive impact on the grain-filling processes and contributed to the development of better quality. As a consequence of the significantly lower amount of precipitation during the generative phenological phases, the worst quality parameters were realized by the varieties in 2011.
In respect of crop year effect, 2010 was unfavourable for the amount of yield, but the most beneficial for the quality. 2011 was the most advantageous for the yield amounts but disadvantageous for the quality parameters. Although in 2012 extreme crop year effects were experienced after each other (dry and warm spring, moist and warm summer), the yield average and quality trait values were close to the yield averages of 2011 and quality parameters of 2010. Analyzing our results we can state that the average crop year was favourable rather for the yield. The appropriate amount of precipitation during the whole 2010 and that during the generative phenophases in 2012 favoured the development of good quality.
Consequently, the appropriate amount of precipitation is essential for the development of good quality during the grain-filling period. The negative crop year effects were only compensated but not eliminated by the good nutrient supply. Genius achieved excellent yield averages but performed worse quality parameters than Mv Toldi, whose quality parameters were outstanding but the yield averages fell slightly behind those of Genius. Considering the yield results, the variety Genius turned out to be the best, while Mv Toldi was the best in quality.

The scientific background of competitive maize production
33-46Views:276The 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.

Examination of drought stress of two genotype maize hybrids with different fertilization
53-57Views:110In the growing season of 2019, we analysed stress resulting from climatic factors on maize hybrids of different genotypes, with the aim of gaining a better understanding of the physiological responses of each hybrid, which might support the elaboration of a cost-effective irrigation plan.
Our experiments were carried out at the Látókép Experimental Station of the University of Debrecen on calcareous chernozem soil in a small-plot long-term field trial with strip plot design. In the scope of the experiment, N-fertilizer doses were applied as basic fertilizer and top-dressing in addition to the non-fertilized (control) treatment. The 60 and 120 kg N/ha doses applied as basic fertilizers in the spring were followed by top-dressing in the V6 phenophase with a +30 kg N/ha dose. Measurements were carried out with the involvement of the Renfor early (FAO 320) and Fornad (FAO 420) late maturity hybrids-
The stomata of the plants became more and more closed with the progression of the phenological phases; their stomatal conductance decreased. However, the hybrids responded differently to environmental stress. In the case of the Renfor hybrid, the highest conductance (669 mmol/m2-s) was recorded in the V12 phenophase with the 150 kg N/ha treatment. The stomata were more open due to the high turgor pressure, allowing plants to evaporate properly. The plant was in its worst physiological condition on 2nd July, at the time of the appearance of the last leaf in the case of the 120 kg N dose (224 mmol/m2-s). The value measured in the V12 phenophase has already shown that the stomata were closing due to the self-regulating system of the plant. It would have been necessary to dispense irrigation water following the measurement. This confirms the finding that water stress can be prevented by measuring stomatal conductance.
In the case of the Fornad hybrid, stomatal conductance was the highest on 12th June (630 mmol/m2-s) in the 90 kg N/ha treatment and it was the lowest (183 mmol/m2-s) in VT (emergence of the last leaf) phenophase in the 60 kg N/ha treatment. In this case, the appropriate time for applying irrigation water would have been early July, when the conditions for the plants were still adequate. Subsequently, the stomata began to close due to a reduction of the water resources available to them.
There was a significant correlation between soil moisture and stomatal conductance, as well as between temperature and stomatal conductance.

Examination of the sub-regions in the North Great Plain Region
158-163Views:85Before 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. -
Role of living bacteria and other amendment in early development of maize
53-56Views:113Different bacteria and wood ash, as a possible micro-nutrient, and liming material, was examined in our experiment on the early growth of corn seedlings.
The development of renewing energy resources includes the use of energy grasses and energy forests. The intensive land use in forestry and in agriculture may cause the acidification of soils due to the harvest, or leaching of cations. To maintain the sustainability of soils necessary to maintain it’s the buffer capacity, and pH. Beside the lime the wood ash can is one of the most effective sources to provide the sustainability of intensive land use. The soil born micro organisms play a significant role in the maintenance of soil quality. The bio fertilizer, that contains soil originated bacteria (Azotobacter, and Bacillus sp.), was used in the experiments. The plants release several organic acids by their roots lowering the soil pH, and make more available the sparingly soluble minerals. The amounts of released organic matter depend on stress intensity, as the high pH is. The soil life has a significant role to keep the soil conditions on sustainable level, since there are several similarities in nutrient uptake mechanism between the bacteria and higher plants. Advantageous effects of bio-fertilizer were observed in our experiments.
We came to the conclusion that the use of wood ash is recommended instead of lime for the improvement of acidic soils, on the evidence of its pH increasing effect. The wood ash contains several micronutrients in an optimum composition for forestry and agricultural plants. The solubility of heavy metals is very low; therefore there is no risk to use the wood ash in the agriculture and in the horticulture by our experiments. The retardation of growth at higher ash doses can be explained by the modification effect to the soil pH, as far as the original soil pH was pH 6.8, and when ash was given to the soil, the pH increases to 7.8 pH, that is unfavourable for the uptake of most nutrients.

Microgreen leaf vegetable production by different wavelengths
79-84Views:148Microgreens are becoming more popular in gastronomy, especially as a salad ingredient. In this study, two plant species belonging to the cabbage family were grown as microgreens, namely red cabbage and broccoli. Three different light-emitting diodes (LEDs) were used in the experiment, blue, red, and combined (blue:red) lighting. The experiment was carried out by 118 µmol-2 s-1total Photosynthetic Photon Flux (PPF), LED lighting was applied for 16 hours a day. Blue light primarily stimulates leaf growth, while red light promotes flowering. In our experiment, blue and combined lighting favorably affected plant development, yield (~3000 g m-2), chlorophyll-a (~8.0 mg g-1), and carotenoid content (9.0 mg g-1). However, the red light resulted in reduced harvest yields (~2200 g m-2), chlorophyll-a (~6.0 mg g-1), and carotenoid content (~7.0 mg g-1). The development of red cabbage was favorably influenced by the blue spectrum, while the combined spectrum favorably influenced the development of broccoli.

Studying the effects of traits in the genotype of three maize hybrids in Hungary
97-101Views:311In this study, we selected three hybrids (Armagnac, Loupiac, and Sushi) for evaluation of the effect of traits in genotype in Debrecen. In 2017, the total rainfall from May to October was 314 mm in Debrecen, which was 236 mm in the winter period before sowing. The obtained results showed that there was a positive correlation between the weight of the cob maize and the rate of seed/cob, number of rows with number of seeds in column and outer diameter ear with weight of cob and number of rows in grain per ear and the rate of seed / cob; Also, there was a negative correlation between grain weight in ear with seed/cob rate, outer diameter ear and the rate of seed/cob and outer diameter ear with the number of leaves. There was a positive correlation between stem diameter, Seed/cob rate and the number of nodes by GGE biplot. In addition, there are traits of weight of all seeds and outer ear diameter that had the highest effect on average yield. Moreover, the number of seeds per row showed the least effect on the average yield of hybrids.

Discussion of an Electronic Examination System in Agricultural HigherEducation
160-163Views:69The development of an internet based electronic examination system at the University of Debrecen Centre of Agricultural Sciences, Department of Land Cultivation and Regional Development was enforced by the dynamic increase in the recent years in the number of students participating in classes taught by the department staff. This paper covers the system’s historical background, the usability factors we were focused on during its development, and the experiences of the testing phase.
The findings of a questionnaire carried out among our students aimed to clarify the acceptance, expectations and fears of future users. -
Periphery formation and economic-social conflict
87-90Views:109The timeliness, significance and importance of the study is sensitively shown by the fact that a large part of the Tisza region is slowly being moved to the periphery in the slowly modernising and changing economic and settlement spatial structure of the Great Plain. This situation is also deepened by the fact that the social and economic backlog increases in the majority of the region, as one third of the 33 most disadvantaged small regions in Hungary can be found here. This study basically contributes to the establishment of the development of the Tisza river’s spatial environment and the development of new solutions.

Evaluation of striptillage and conventional tillage in maize production
37-40Views:156Tillage changes soil properties and the way how the environment affects those properties. Soil properties and environment determine the rate of water movement in liquid and gaseous form into and out of soil. Based on the experimental database of the Institute of Land Utilisation, Regional Development and Technology of the University of Debrecen, Faculty of Agricultural and Food Sciences and Environmental Management and the KITE PLC, various cultivation systems were examined with maize (Zea mays L.) as indicator plant in Jász-Nagykun-Szolnok county. The sample area can be found in the outskirts of Kenderes on a meadow chernozem soil. On the examined plot, strip-tillage, subsoiling and moldboard ploughing were performed, each on 4.5 ha, respectively. The purpose of the present study is to compare these cultivation systems according to the soil- and maize kernel moisture content and to the yield based on the years of 2012 and 2013.

Social capital as a resource influencing social and economic processes
69-73Views:93The concept of social capital became well-known in the 1980s and as a non-material resource existing in the society and today it is one of the most popular fields of the sociological and economic research. There are many definitions of social capital, but there is a common point that they all have: a network-related interpretation. The networks are made up of discrete elements, which have some kind of relation between them. Accordingly, social capital is manifested in the totality of the relations between elements (actors of the economy and society) forming the network not in the elements themselves (e.g. human capital). This is a resource which influences the social and economic processes of a community – even if it is a community of a micro region or a nation. Consequently, social capital has a significant impact on the development and improvement of an area or a territorial unit. In this paper, I try to summarise the information concerning social capital and to sketch the relation between rural development and social capital as one of the immanent resources of a territorial unit.

The effect of irrigation on the yield and quality of maize (Zea mays L.) hybrids
143-147Views:156In this study, the effect of water supply on the quality and productivity of different maize hybrids was observed.
Maize production is influenced by many agro-technical factors such as nutrient supply, plant density, environmental factors, water supply and temperature. Good soil quality and adequate technology significantly reduce the unfavourable effect of crop year. The impact of fertilization, crop rotation, irrigation and plant density on maize yield was greatly affected by crop year and crop rotation. The main constituent (69–75% dry matter concentration) of maize seed is starch, however, its increase can be achieved only to a limited extent, as increasing the starch content will reduce other parameters, especially protein content. Significant nutrient content improvements can be achieved by appropriate hybrid-site connection and the use of adequate technology. Protein content reduction with optimal water supply can be positively influenced by the appropriate nutrient supply for the hybrid.
The experiments were carried out at the Látókép Experimental Site of Crop Production on calcareous chernozem soil. The weather of the examined year, which was partly favorable for maize and partly unfavourable in other respects, was also reflected in the development of maize and yields achieved.
In 2019, we were examining the hybrids of Kamaria (FAO 370), P 9903 (FAO 390), DKC 4351 (FAO 370) and KWS Kamparis (FAO 350–400). Due to the dry soil condition, sowing was delayed, however, the hybrids emerged ideally because rain arrived soon after sowing, which facilitated initial development. Young plants evolved rapidly and dynamically in the case of all hybrids. In terms of heat-demanding bread, the month of May was unfavourable to temperatures below the annual average, but the higher amount rainfall helped the development. However, due to the drier period in early July, 25–25 mm of irrigation water was applied to half of the experimental areas on July 1 and 15.
The aim of our research was to determine the best population density for hybrids under favourable soil conditions (calcareous chernozem soil). In both irrigated and dry conditions, a crop density of 75,000 crops were the most favourable for the Kamaria hybrid. The P9903 hybrid in the case of a crop density of 85 crops proved to be ideal and the DKC4351 had an optimal population density of 95,000.
However, it should be taken into consideration that, in the case of soils with poor water management, the drought sensitivity of the crop stand may increase at a population density of 95,000.
As a result of irrigation, yield increased and the difference between the examined plant numbers decreased. The yield growth was relatively moderate (341 kg ha-1 – 1053 kg ha-1), which makes the economicalness of irrigation doubtful in the given year.

Investigation of the Effect of P-Supply on Maize (Zea mays L.) Development
171-173Views:77Quantification of plant development is important in areas where the actual dates of certain phonological stages should be identified. The influences of different ecological factors are put into algorithms by crop modellers. In this process the effect of plant nutrients are not yet well quantified. This paper gives data on the effect of phosphorus on maize development prior to flowering stage. The main conclusions are as follows: 1. In lack of phosphorus more degree days are needed for flowering then in case of well P-supply. 2. The effect of P is seen not on leaf initialisation (i.e. final eaf number is the same) but rather on the phyllochron interval. 3. P effect on phyllochron interval can be observed at the younger stage (prior to leaf number 10) but not later.

Analyzing the Population Retaining Ability and the Ability to Economically Provide for a Population in the Micro Region of Püspökladány
210-219Views:69According to the data of population density, 98% of Hungary’s territory has rural features. Gaining EU supports, in order to focus on developing the most underdeveloped communities, and in order to decrease – not to increase – the differences between communities, the establishment of priorities and determination of the rank of rural communities based on their development potential is necessary. The claim of measurability arises because of comparison and classification. A possibility or a target area of measuring is analysing population retaining and income producing capability of rural areas.
To gain adequate, many-sided information about the development potentials of a given community, micro- or macro region, complex condition survey, as well as secondary information completed with empirical data and subjective value judgment is essential. The aim in every case is to gain experience of the present condition via determining the direction of change.
In this study, I deal with the clarification of the definition of population retaining ability and the ability to economically provide for a population and introduce the most important results of the inquiry with questionnaires completed in the frame of an empirical survey. -
Effects of different crop years and sowing date on maize yield
93-96Views:123We carried out the tests in the flood meadow soil formed on the alluvial cone of Nagykereki, Sebes-Körös belonging to the Bihar plane small region. The aim of the study was to analyse the effect of the different sowing date of maize on the yield trend based on a comprehensive study conducted for 6 years (2007–2012).
The sowing date of maize hybrids is a factor that significantly influences yield, however, its effect is not significant in each crop year. In the years when the date of sowing has a modifying effect, the reliable yield level can be reached with optimal sowing date management (24 April).
The advantage of early sowing (10 April) proved to be dominant in the year of 2012, the seeds were placed into the still wet soil therefore shooting was more balanced. Maize seeds sown at the time of optimal (24 April) and late (10 May) sowing dates were placed into the already dry soil, which deteriorated germination and the strength of early initial development that had an effect on the yield.

Integrated development strategy of the catchment area of the Tisza river
31-36Views:181The main challenge for mankind has always been to eliminate the borders of its living space, as well as to explore and discover its new faces. Contemporary literature strengthens this postulate. It is the preference of the experts of various fields in spatial analysis is to consider space to be repairable, changeable and organisable. In accordance with this axiom, the five affected countries in the catchment area of the Tisza river (Hungary, Romania, Ukraine, Slovakia and Serbia) worked out an integrated, mutual standpoint to support the problems of the catchment area and to exploit its opportunities with the aim to support transnational cooperation. They laid great emphasis on the existing resources which could become the driving force behind regional development directions. This study contains the summarised outcomes of the TICAD project (SEE/A 638/4.2./X) which was drawn up as a result of cooperation between renowned institutions of the five affected countries within the South East Europe Transnational Cooperation Programme (lead partner: VÁTI, Hungary).

Public opinion on the settlements’ environment and the use of renewable energy sources in the Micro-region of Gyöngyös
267-272Views:59This paper intends to give an overview on some results of our studies carried out on the public opinion of the above aspects (settlements’
comfort level and the use of renewable energy sources) directly or indirectly linked to the topic of climate change and possible adaptations.
These studies were carried out by applying questionnaire survey in the (altogether 25) settlements of the Gyöngyös Micro-region.
Knowledge on general human perceptions related to climate change and its impacts is considered to be important as it should advance the
elaboration of adaptation and applied scientific works. They are highly required as rural areas, due to their closer relationship (dependence)
to the physical environment, are more susceptible to changes resultant from the climate change with their possibilities to adaptation also
being impeded.
The beauty of environment plays an important role in the settlements studied within the micro-region with more than two third of pollees
opting the environment as a factor they most proud of, especially among those residing in the villages for more than 10 years. It can be
presumed that any change in this environment would greatly impact their everyday life and emotional relationship to their home villages. The
overall picture after analysing the public opinion on the use of renewable energy source (as possible way of adaptation to the impacts of
climate change) is rather controversial. Even basic knowledge and information are limited regarding the relevant technologies calling
attention to the importance of raising environmental awareness and providing full information seems to be essential and should be
implemented, through the media and education. -
Age-Related Anatomical and Morphological Development of the Ruminant Stomach in Kids
55-56Views:111We observed the anatomical and morphological development of each compartment of the ruminant stomach in 3. 6. and 14 week old kids. Weaning from milk to roughage foraging, depending on the kids’ ages, stimulated the development of the rumen and reticulum, and decreased the abomasum portion. A 3 week old kid’s rumen has dense and thin papillas but, with advancing age and with roughage foraging, the number of the papillas on cm2 decreases and their width increases. The omasum tertiary laminae and especially the quaternary laminae are observable only in the advanced age categories.

The impact of climatic factors on the relative chlorophyll content and yield of a maize hybrid in a long-term experiment
71-77Views:193The impact of the climatic factors of crop year on the relative chlorophyll content of maize was examined for three years. The examinations were carried out on the Látókép Experiment Site of the University of Debrecen on calcareous chernozem soil in a small-plot, non-irrigated long-term field experiment with strip plot design. In addition to a non-fertilised (control) treatment, nitrogen (N) fertiliser doses were applied as base and top dressing. The 60 and 120 kg N ha-1 base dressing doses were followed by two top dressing doses at the V6 and V12 phenophases.
Averaged over the different fertiliser treatments, SPAD readings increased in all three years as the growing season progressed. The highes SPAD value increase was observed in the average crop year (2017) at the V12 phenophase (11.8), which further increased at the R1 phenophas, by 3,7. No significant Spad value difference was observed between the average (2017) and the dry year (2018) at the V6 growth phase. However, in the wet crop year (2016), the V690 treatment provided the statistically highest relative chlorophyll content (46.8). At the V12 phenophase, the base dressing dose of 120 kg N ha-1+30 kg N ha-1 (V6150) showed to be successful in two years (2016 and 2018), while in 2017, the base dressing dose of A60 was successful. The impact of crop year on relative chlorophyll content can be clearly shown at the R1 growth stage. In all three years, the significantly highest relative chlorophyll content could be achieved at different nutrient levels: A60 in 2016, V6150 in 2017 and V690.
In a wet year (2016), higher yield could be achieved as a result of the 60 kg N ha-1 base dressing and 30 kg N ha-1 at the V6 growth stage (V690) as top dressing in comparison with 2017 and 2018, when higher fertiliser dose (120 kg N ha-1 base dressing and 30 kg N ha-1top dressing at the V6 growth stage) was needed to achieve a significant yield surplus.
Altogether, averaged over the different treatments, the highest yield (12.48 t ha-1) was observed in the wet year, when the relative chlorophyll content was also the highest (50.6).

Comparative analysis in residential property price level and price dynamics in urban and rural areas of Hajdú-Bihar County
85-90Views:113In modern market economies residential real estate prices, price shifts and their correlations with macroeconomic factors are surveyed quite frequently. However, in contrast with the wide scope of foreign examples, so far existing analyses in Hungary have ignored examining relation and extensity of macroeconomic indicators and failed to examine their effect on real estate pricing. The scope of this survey is to highlight these potential correlations and thus develop new aspects of analysis. Although the examination needs further extension both in time and space, the results of this survey may help to understand the importance of the responsible management of the most precious element of national wealth from the perspective of sustainable rural development.
Based on my preliminary results, there exists a strong correlation between the number of inhabitants of a settlement and the average real estate prices. Nevertheless, the correlation seems to be significant only for cities. In the case of smaller settlements the correlation still exists but at a lower level. As opposed to the results of former publications and my own expectations, no direct link could be tackled between the amount of income tax paid by private individuals and real estate prices either in the cities or in the villages within the territory and time span examined in my analysis. Although this correlation is measurable on a macro-economic level, my micro-regional analyses revealed the complexity of asset pricing and price volatility. Continuing this survey, my goal is to identify the hidden factors influencing real estate prices, whose thorough mapping may promote conscious rural development.

The future of apple growing in the Northern Great Plain region
35-38Views:90We revealed and assessed those macroeconomic data which enabled us to identify the outstanding role of agriculture and within it that of fruit production. Based on this, it can be said that soil is the most important natural resource of Hungary. The appropriate combination of the additional resources required for production, labour and assets can provide a comparative advantage for the Northern Great Plain Region.
The Northern Great Plain Region is one of the most underdeveloped regions in Hungary, so its development is a political objective. When analysing the economic sectors in the region, the important role of agriculture is obvious and it is also clear that the industry and the tertiary sector can only have an alternative income generating role in the future also. Therefore, it is important that the regional development funds of Hungary and the European Union are directly or indirectly aimed at improving agricultural development and competitiveness. -
Effect of different N doses on maize yield and quality
97-101Views:144The effect of N doses on the yield and nutritional values of the Sushi (FAO 340) maize hybrid were analysed in three years (2018, 2019, and 2020). The analyses were performed at the Látókép Experimental Station of the University of Debrecen on calcareous chernozem soil, in a striped, small-plot, non-irrigated long-term field experiment. In the experiment, in addition to the non-fertilized treatment (A0), the N-fertilizer doses were applied as basic fertilizer and top dressing. The 60 and 120 kg N ha-1 dose (A60, A120) applied as spring basic fertilizer were followed by two phases of top-dressing in V6 (V690, V6120) and V12 (V12150, V12180) phenophases; the amounts were +30 and +30 kg N ha-1.
Maize yields were affected to varying degrees by crop year. The highest yields in 2018 and 2020 were recorded in the same V6150 treatment, while in 2019 the highest yield was obtained in the A120 treatment.
Increasing the N doses resulted in an increase in the protein content of the maize kernel. Depending on the fertilizer treatments and the crop year effect, the protein content of maize kernels varied between 6.2–10.2 g x 100 g-1. In all three years, the protein content was the lowest in the control treatment (A0) and the highest in the V6150 treatment.
The starch content ranged from 70.7 to 77.9 g x 100 g-1 in the average of the three years. In 2020, it was significantly higher in all nutrient treatments than in the other examined two years. The highest starch content - except for 2020 (A120, 77.9 g x 100 g-1) - was recorded in the A0 treatment (74.2, 72.3 g x 100 g-1).
The oil content of maize kernels varied between the values of 3.8 and 5.2 g x 100 g-1 in the average of three years. In terms of oil content, the results for 2018 and 2019 can be considered the same, while in 2020 it was significantly lower. Fertilizer treatments did not significantly affect the oil content of maize in any of the years.
The fertilizer dose applied in the V12 phenological phase was not effective in terms of yield and nutritional content (protein, starch and oil content).
