The effect of different sowing depth on the yield and yield-forming elements of maize
173-176Views:34On a global scale, maize is an important food, feed and industrial crop, with an increasing production area (Nagy, 2007 and 2021). Among the environmental impacts, extreme weathering factors caused by climate change are causing serious problems for crop stability, and maize is no exception.
Precision farming is today's most innovative agrotechnical approach, which can greatly increase crop safety and reduce costs by exploiting the genetic potential of our soils and the hybrids we use (Torres, 2012).
Sowing is one of the most important agrotechnical elements, and with good seeding we can ensure that we have all the requirements of a high yielding, high growing crop (Pepó, 2019). In the case of sowing, it is important to place the seed in moist soil to provide the optimum environmental conditions for the crop to ensure uniform emergence (Széles et al., 2020; Shrestha et al., 2018).
Precision planting is the market leading technology in precision planters in the United States, and when cooperating with them we looked for methods to optimise the depth of sowing and to monitor the effect on yield by studying the initial development of the plants. The seeder was equipped with the company's SmartFirmer soil scanner integrated into the seed drill. Automatic seed depth adjustment based on soil moisture is an exceptional solution for uniform emergence and drought protection.

Spatially Discrete GIS Analysis of Sampling Points Based on Yield and Quality Analysis of Sugar Beet (Beta vulgaris L.)
32-37Views:89Fulfilment of the increasing quality requirements of sugar beet production can be analysed with sampling of plants and soil at the cultivated area. Analyses of the spatial characteristics of samples require exact geodetic positioning. This is applied in practice using GPS in precision agriculture. The examinations were made in a sample area located in north-western Hungary with sugar beet test plant. According to the traditional sample taking procedure N=60 samples were taken in regular 20 x 20 m grid, where besides the plant micro and macro elements, the sugar industrial quality parameters (Equations 1-2) and the agro-chemical parameters of soils were analysed. Till now, to gain values of mean, weighted mean and standard variance values, geometric analogues used in geography were adapted, which correspond to the mean centre (Equation 3), the spatially weighted mean centre (Equation 4), the standard distance (Equation 5), and the standard distance circle values. Robust spatial statistical values provide abstractions, which can be visually estimated immediately, and applied to analyse several parameters in parallel or in time series (Figure 1). This interpretation technique considers the spatial position of each point to another individually (distance and direction), and the value of the plant and soil parameters. Mapping the sample area in GIS environment, the coordinates of the spatially weighted mean centre values of the measured plant and soil parameters correlated to the mean centre values showed a northwest direction. Exceptions were the total salt and calcium-carbonate contents, and the molybdenum concentration of the soil samples (Table 1). As a new visual analysis, the spatially weighted mean centre values of the parameters as eigenvectors were projected to the mean centre values as origin. To characterize the production yield, the raw and digested sugar contents of the sample area, the absolute rotation angles of the generated vectors were determined, which indicate numerically the inhomogenity of the area (Figure 2). The generated spatial analogues are applicable to characterise visually and quantitatively the spatial positions of sampling points and the measured parameters in a quick way. However, their disadvantage is that they do not provide information on the tightness and direction of the spatial correlation similarly to the original statistical parameters.

In and out of the crisis − Greece
33-36Views:178Facing an unprecedented crisis, both Greece and the international actors have been struggling to facilitate a solution that assures sustainable growth through restructuring the economy and the national accounts. However, enduring solutions cannot be born but through a very thorough understanding of the root causes and the nature of the problem. A country far from fully exhausting her resources is also experiencing increasing tension in the society. Highlighting some key characteristics of the most relevant parties, the factors undermining the society and the real growth potential of the country will be addressed and challenged with key economic principles. This cross-sectional study aims to pave way to a more comprehensive approach to prevent any disagreements or delays that was experienced in late 2013. The findings refer to the assets of the country and identify some basic requirements to boosting the Greek economy. The lessons learned and the growth potential of the country is being discussed in the concluding remarks, pointing to some factors to be considered in the future.

Economic impacts of applying EU animal protection regulations in hog breeding farms
76-80Views:87Hungary’s intention to join the EU makes it necessary to adopt, introduce and use the EU system of law. In Hungary, the legal control of animal welfare has improved (XXVIIIth law in 1998); however, most of our pig farms do not meet the EU animal welfare law requirements for some reason. We examined 9 pig farms in Hajdú-Bihar, Borsod-Abaúj-Zemplén and Heves counties. We chose those farms which use the combined breeding
technology most frequently used in Hungary. The most important part of the welfare directive is the definition of the minimum space per animal. We analysed the data in comparison with EU laws. On the basis of the analysis, it can be said that there is a narrow cross-section: the breeding of piglets. During the cost analysis, we analysed cost and highlighted the permanent cost. We studied how these costs would change if EU animal welfare laws were observed. We also examined the specific data per 1 sow and per 1 kilogram of slaughter pig. We compared the present data (1999) with those we get if EU animal welfare laws concerning minimal space per pig were now followed. It can be stated that after decreasing the sow live-stock in accordance with EU directives, the permanent cost would increase by 17,7% per sow. If the required space per sow were provided, the total cost per sow would increase by 1,9% from 421,1 thousand forints to 429 thousand forints, on average. This would mean a decrease of 7,9
thousand forints profit per sow. As with the decrease of the number of sows, the number of slaughter pigs also decreases. Total cost per 1 kg of slaughter pig would increase from 214,7 forints to 218,2 on average. -
Correlation of pruning time and fruiting part differentiation of sweet cherry cultivars
131-134Views:79There are several extended studies in sweet cherry production in Hungary and all over the world i.e. for creation and maintainence of smaller tree crown and high density orchards. The use of suitable dwarf rootstocks for this fruit species are very limited. On one hand, most of the draf rootstocks do not cause enough growth reduction and on the other hand these rootstocks are get old very quikcly and their fruits become small, and therefore, they not serve the requirements for intensification. In summary, there is a need for those rootstock which are vital, regeneration enhanching and delay ageing. Due to ensuring above features, Prunus mahaleb is still an obvious solution for intesive production. Increasing intensification can be obtained by use of modernisation of technological elements and suitable cultivar choice.
According to this increasement of intensity through application of novel technological elements (timing, manner and severity of pruning) and selection of the proper cultivar is implement able. Important differences are experienced between sweet cherry cultivars in their growth attributes, light demand and dynamics of fall back in regenerative potencial of different aged wood parts. From this point knowledge of the abow detailed is very important in order to maintain rentability of already established plantations. Our work shows the formation of production part in
9-year old plantation with spike spindle and free spindle crown forms depending on pruning timing (winter, summer) and determining of their various effects. -
The purple coneflower’s (Echinacea purpurea L.) nutrient requirements investigation in a small plot trial
95-99Views:146During our research, we investigated the purple coneflower's (Echinacea purpurea L.) drug yield and drying loss change with different fertilization settings in a small-plot trial. We measured the raw and dry drug yield, which we harvested in 2016 and in 2017, as well as the drying loss of these yields. Harvest and all other works were performed manually. We dried the harvested herba under prenumbra for three weeks. Based on the obtained data, every fertilization settings’ yield was less than that of the control plots in 2016. We measured the highest drying loss in relation to the N60P80K120 supply in this year. In 2017, we measured the highest yield data in the N75P100K150 fertilization setting.We made single-factor variance analysis to investigate the connection between the quantity of the raw, the dried herba, the drying loss and the different nutrient settings -
Use of essential trace elements enriched Artemia in the larval rearing of barramundi (Lates calcarifer)
11-16Views:153Artemia is a vital nutriment in the rearing of barramundi (Lates carcarifer), however it’s mineral trace element content does not cover the requirements of the larvae. In our experiment the assumption was wether the cobalt, zinc and manganese concentration of Artemia could be increased during a 24 hours of enrichment period, as well as we wanted to investigate the resulted interactions between the elements. For this purpose 50, 100 and 1000 mg l-1 cobalt-chloride treatements (Co50, Co100, Co1000) were applied while in the case of 50 and 100 mg l-1 treatments the enrichment was also complemented with zink-sulphate and manganese-chloride in the same concentrations. According to the results the zooplankton were able to accumulate cobalt in higher amount, and yet zinc and manganese had no significant effect on each other, a strong synergistic effect occurred between cobalt and manganese. After the enrichment period the impact of essential trace element supplemented live feed on the survival and growth of barramundi larvae was also studied. The experiment was carried out by using 15 days-old larvae applying a total of 9 treatments for two weeks (Control, Co50, Co100, Mn50, Mn100, CoZn50, CoZn100, CoMn50, CoMn100), in duplicates. Considering the per cent of survivals, no significant difference was observed between the treatements (P>0.05). In the case of CoMn50 and CoMn100, the loss statistically increased (P<0.05) compared to the Control (80.5±4.95%) group. Our results show, that the Mn100 and CoMn100 treatements resulted in ignificantly higher (P<0.05 ) in divid ual bod y w eight s, how ever taki ng the survival also into consideration the Mn100 treatements proved to be the most
effective. -
Investigation of the production parameters, nutrient and mineral composition of mealworm (Tenebrio molitor) larvae grown on different substrates
129-133Views:226During the rearing of mealworm (Tenebrio molitor) larvae, the optimisation of the growing substrate has a particular importance. The application of the appropriate substrate is a fundamental pillar for intensive and safe production. The requirements for substrate include the lack of toxins, high nutrient and micro-macro element content. The aim of this study was the evaluation of the effects of different substrates on the production parameters, nutrient and mineral composition of the mealworm larvae. The experiment lasted through 14 days. 5 treatments were set up at, where the variable was the substrate. The test system consisted of 25 units (5 treatments and 5 replicates). 10 mealworm larvae per unit, (total of 250 larvae) were used at the beginning of the experiment. Regarding the substrates, our study included sweet potato (SP), may turnip tuber (MT) and may turnip leaf (ML). In addition to the plant by-products, wheat flour (WF) and wheat semolina (WS) were used as control substrates. Trace element uptake and production parameters of the larvae were determined at the end of the experiment. Regarding the production parameters, it can be stated that the wheat semolina (0.081 ± 0.005 g) and wheat flour (0.069 ± 0.007 g) substrate used as control gave the best results for the final body weight. In terms of plant raw materials and by-products, sweet potatoes (0.063 ± 0.007) can only be recommended as substrate, while may turnip tuber and may turnip leaf produced significantly lower final body weight results (MT=0.034 ± 0.002 g ; ML= 0.036 ± 0.002 g). The nutrient composition of the larvae was not affected by the substrate, these results confirmed the high protein and fat content reported in the literature. The results with the production parameters were contradicted by the micronutrient content. Larvae reared on may turnip leaf (ML) and tuber (MT) showed the highest values for most of the macro- and microelements (potassium, calcium, magnesium, iron, zinc, copper) tested.

The examination of human resources in the Hódmezővásárhely micro-region on the basis of human resource hierarchy
91-110Views:75In 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. -
Examination of nutrient reaction of winter wheat after sunflower forecrop
9-13Views:144We tested the fertilizer reaction of four different winter wheat varieties in three different crop years, on chernozem soil, in long-term experiment. We examined the optimum fertilizer requirements and the maximum yield of the varieties. According to our results there were significant differences among the years: the yield of the winter wheat varieties changed between 1.4–6.1 t ha-1 in 2013, 3.8–8.6 t ha-1 in 2014 and 3.2–8.6 t ha-1 in 2015. The yield increasing effect of fertilization was significantly different in the tested years. The optimum level of fertilization was determined by, besides the genetic differences among the varieties, the crop year and the extent of fertilization. In milder winter months, due to the higher average temperatures, yields of winter wheat increased compared to an average crop year.

Role of Sowing Time in Maize Production (Review)
36-39Views:78Many authors, both in Hungary and abroad, have reported on experiments carried out to determine the role of sowing time in maize, but the results are often contradictory. This is hardly surprising, since the maize plant exhibits enormous genetic variability and the hybrids created through selection and inbreeding may have very specific requirements as to sowing date. The year effect, too, often complicates the efforts of scientists to provide clear guidance to farmers on the optimal sowing date for each hybrid.

Correlation between cultivation methods and quality in some vegetable species
313-317Views:124Quality parameters of 5 table root varieties were tested on 3 sowing dates with different cultivation methods: open field on 15 April and 9 July 2010 and under plastic tents on 19 August. The highest red pigment content (betanin) was measured in the varieties Akela and Mona Lisa (~ 80 mg 100 g-1) of the second (July) crop. This crop is in general use in Hungary. In comparison, in the late sown varieties (August, under plastics) a further pigment increase (10–20 mg 100 g-1) was observed in the same varieties as related to the earlier sowing dates. Yellow pigments (vulgaxanthins) showed similar trends. Roots of the late sowing date (with harvest in December) contained the highest vulgaxanthin values (103.3–124.18 mg kg-1).
Varieties reacted differently to temperature changes during the production period and thus to sugar accumulation. In the second crop (July) higher water soluble solids content was measured on the average of varieties (10.12%) in comparison to the April sowing (7.76%). Beetroots of the spring sowing are recommended for fresh market while the second (July) crop with autumn harvest can satisfy industry requirements. Late sowing under unheated plastic tents supply us with fresh beetroot in late autumn and early winter and prolong the usability of plastic tents.
Six lettuce species/subspecies were tested in the open field and under plastic tents in 3 repetitions for nitrate nitrogen, vitamin-C, polyphenol (gallus acid equivalent – mg GAE 100 g-1) and mineral element (Ca, K, Mg, Na) contents. Our measurements showed lower nitrate nitrogen values under plastic than in the open field (89.10± 8.13 and 127.06±14.29 mg kg-1) on the average of genotypes. Lettuce grown in the field had higher vitamin-C content (1.4 mg%) which is nearly 50% more than in plants under plastic. The highest polyphenol content was found in samples from the field with a conspicuous value of 804.17±56.47 mg GAE 100 g-1 in Piros cikória. Samples grown under plastic were richer in mineral elements (Ca, K, Mg, Na) which can be explained by the higher nutrient content of the soil. In this environment superior Mg content was observed in Edivia (4616.33±
311.21 mg kg-1).Besides the well- known headed lettuce, Piros cikória (Red chicory),the red leaved Lollo Rossa and Tölgylevel (Oak leaf lettuce) should be
mentioned which well deserve further testing in order to supply us with nourishing, healthy food. -
Landscape tools to support the educational use of school grounds
63-72Views:28Recent years have seen an increasing emphasis on child-friendly concepts in landscape architecture and urban planning, as well as a growing emphasis on school grounds and environmental education, both in terms of pedagogy and landscape design. School grounds provide places for active engagement with the environment, for experiencing what is taught in class, and, are therefore of particular importance for education and for building children's connection with nature. The aim of this research is to develop a set of landscape architecture tools that can be used to promote child-friendly and education-centered design of school grounds. The research collects and organises the different school ground features, drawing on literature research, and the analysis of the Framework Curriculum. The toolkit presented in this paper lists and evaluates each feature according to its function, its relevance to school subjects and the specific knowledge or skills it can help to acquire, its space requirements and feasibility. To conclude, school grounds offer opportunities for teaching almost any subject and can therefore be linked to educational activities in multiple ways. The results of this research are to be developed into design guidelines in order to be used by designers and teachers alike, to help develop school grounds contributing to the well-being and environmental awareness of new generations.

Overview of higher education funding models
129-133Views:107t can be defined in the course of the review of the financing characteristics of higher education that every model has its advantageous feature which is missing from the others, at the same time; it has its weaknesses as well. None of the basic models can meet the complex requirements of the nowadays society and government, thus the choice between the models have to be based on the preferences of decisionmakers and society. In most countries the combination of models are implemented, which compensate the weaknesses of the basic models, however, the models formed by the combination of different principles are neither perfect.

Fight Against Hunger: A Worldwide Challenge at the Onset of the Third Millenary
3-11Views:75We live in such an era and face such a century, in which the growth of the- world population, the problems deriving from the population explosion will create an unprecedented and never recurring situation for Hungary and the Hungarian animal husbandry as regards the tasks and possibilities ahead us. While presently 6 billion people live on Earth, in the first century of the third millenary the population can reach 10-12 billion and is expected to stagnate around that number.
The Third World, the so-called developing countries struggling with enormous difficulties, makes up for 90% of the annual population growth of 80-90 million people, while the population of the developed countries is stagnant or decreasing. In this aspect, Hungary' s situation is extremely worrisome, because our population has been decreasing for two decades, and according to recent demographic forecasts could drop to 8 million in the next century if the present trend continues. This should be impeded, among others with the contribution of animal husbandry.

Study of traditional folk foods from the point of view of nutrition in Hajdú-Bihar County
47-51Views:110Healthy nutrition is one of the major topics of our days. The occurrence of the so called “civilization diseases” is increasing continuously as a result of the changes in our nutritional habits and life-style. It was thought that folk nutrition at the beginning of the 19. Century had several beneficial effects on health. For this reason it was decided to study the food and nutritional habits of the population of Hajdu-Bihar County around the 1930s on the
basis of literary sources to see how well they do match with modern requirements of healthy nutrition. -
System of relations between competitiveness and social cohesion in the European Union (2007–2020)
39-45Views:131I my current essay I tried to prove that the European Union modified its economic policy due to the financial and economic crisis and the fierce global competitiveness requirements. The main emphasis was laid on the increase of competitiveness. Competitiveness became preferred
to cohesion and the economic and social closing up of the newly joined Middle-Eastern European countries. The funds for competitiveness for growth and employment increase by 6–7% yearly during the financial perspective between 2007–2013. On the contrary the funds for agriculture and rural development decrease by 3% yearly in this period. The tendency remains unchanged during the financial perspective 2014–2020.
This tendency strengthens the establishment of the two speed Europe concept and causes tensions between the core regions and the peripheries. -
Analysis of the Environmental Status of Nagykálló Subregion
362-367Views:93The third smallest region of Szabolcs-Szatmár-Bereg county is the Nagykálló subregion. Its territory is 377 km2 and its inhabitants number 32.526. Due to the fact that industrial development arrived late, the environmental status of this subregion was saved from serious ecological degradation. The quality of the environment shows a reasonable picture in many respects, comparing to the general survey of the country. The air quality of the region can be qualified as acceptable. Leaving some critical points out of consideration, it is better than the national average. It is favourable from the human environment point of view that the region is free of extremes, and has a balanced climate. The supply of drinking water is above 95%, and the remainsing water requirements are supplied by artesian wells. The water supply network is fully extended in the subregion. The most significant environmental noise source is traffic, including public road traffic, which causes a problem in the town of Nagykálló. The situation of the collection, transportation, and placement of the settlement’s solid wastes show a similar picture to the status of the country. The environmental status of the region is included in the SWOT analysis.

Perspectives of air cargo activities in case of Debrecen International Airport
131-134Views:138The improvement of Debrecen International Airport has been taking place for more than a decade. The goal is to revitalise the domestic and international aviation of regional centres and connect the Debrecen centred economy zone with other industrial and commercial regions. Considering the market segments of the air cargo industry, and sizing up the requirements of the enterprises, we are seeking to answer for what possibilities an air cargo operation has, and scheduled cargo flights, what alternatives the location of a cargo base has. Getting to know the technical background of ground handling, communication, safety, and security, we can state that the airport is able to handle international cargo aircrafts as well. Regarding to the quantity of frights, we find that there is a possibility of two flights per week. There is minor need of handling dangerous or unique parcels. The surrounding area of working zone is an excellent territory for locating and building cargo facilities, and its technical background. In case of continuously increasing traffic it is suggestible to use the territory behind the apron as a first step of the development. As the activity extends the second step could be the improvement of the southern zone just beside the runway. This way primarily the
scheduled air cargo flights could appear, then as the traffic of commercial scheduled flights increases simultaneously could grow the amount of
small parcel transportation. -
Economic policy strategy of UNITAB
83-90Views:72Under the leadership of the International Association of Tobacco Producers – UNITAB – there is a struggle going on for stabilizing the situation of European tobacco growers. UNITAB unites the tobacco associations and tobacco growers of all EU countries.
Tobacco production ensures economic stability for more than 100 thousand small- and medium-sized farms in the rural areas of 10 EU countries. In addition, its social importance in the survival of rural communities is emphasized by the 400 thousand direct or related seasonal jobs.
Within the framework of the CAP reform, the European Union is gradually changing the regulations of production. This is based on the decoupling of subsidies, which will be implemented in two phases. Between 2006 and 2009. the decoupling will be 40% and then after 2010, 50% (the other 50% will be used for restructuring within the second pillar). The question is raised, how will the second 50% be restructured to the second pillar. Between regions and how it can be ensured that this support would go to tobacco production.
With its participation in the principles of the European Tobacco Charta, UNITAB targets for production under economically-balanced conditions, the production of products meeting the customer requirements, consideration of the working conditions (especially for seasonal workers) and adherence to the health regulations related to the consumption of the end product already in the production and environmental protection. They aim to ensure the survival of the sector via tobacco growing with sustainable development and high quality. To maintain the continuity, there is a need for the support of regional, national and EU authorities. Future of the sector is dependent upon adaptation of tobacco growers and upon meeting the social expectations.
According to UNITAB, efforts should be made to modify the decisions so that the majority of the funding could be used by the grower. The tobacco industry has been able to effectively fight for its survival. -
Examination of different grain hardness varieties of the grinding technology properties of wheat
423-435Views:185In the mill industry, the purpose of the grinding technology is to separate wheat endospermium and shell and to recover grists. The most important and the highest energy requirement operation is shredding. Flour quantity and quality produced from wheat depends on the variety of wheat that will be shredded, the type of grinding equipment and the condition used before the grinding. For this reason, during my experiments, I ground two grain structured varieties of wheat in laboratory conditions using a disk grinder, stone grinder and roll grinder in air-dry and conditioned states. We measured the equipment’s performance and the produced grist’s particle size distribution, followed by the calculation of the energy requirements of the grinders. In the grinding experiments we compared the ash contents of the different particle sized grist’s fractions to map the wheat’s particular properties.

The Present and Future of Tokay Aszú
87-92Views:87Tokay wine is Hungary’s noblest wine. Beyond doubt, it is one of those uniquely Hungarian products, which has been without rival for centuries. Today the role of quality has become increasingly important and consumers who are ready to pay more for quality wines expect it. This wine will be able to get back its original popularity if the message of its excellence reaches the public. Knowledge of historical wine-producing regions constitutes a part of basic education and wine-marketing could take important measures to spread it since good products need to be sold properly and consumers require information about wines – with gastronomy – and wine producing regions.
With foreign invested capital, advantageous changes have been started in Tokay-Hegyalja. However, there is much still to do in order to produce, sell and consume Tokay wine on such conditions that are really worthy of a Hungaricum. It is essential to approach the famous oenologists of Europe and the world and to establish suitable production conditions for every winegrower. In addition to following consciously prepared wine-marketing directions, our country needs to make an expected name for this Hungaricum. These aims are important mainly because of approaching EU-accession. There is timely to study on what conditions Hungarian viticulture and oenology could access. It would be a great success of the Hungarian delegation if they could make current Hungarian laws of Tokay-wine-production accepted in the EU. Of course, all of these would be valid after EU-accession. During the pre-accession period, our country needs to fulfil several stipulations. For example, origin-protection, establishment of a registry system, law harmonisation, development of an institutional system.
Strengthening of home consumption has always been an inspirational tool in a product’s life cycle. It is important not only to take the requirements of foreigners into consideration and to produce for export, but we also need to satisfy the home market. Considerable stress should be laid on establishing and preserving viticulture. Increasingly, buyers expect high standards and they are ready to pay more for quality wines. They also demand appropriate professional information and consultation. So there is a lot to do and theoretical approach should be followed by action. In order to get to know what quality expectations exist, we have to examine the consumers of the Hungarian wine-market. Study of the Hungarian people’s consumption behaviour, referring to Tokay „aszú”, was closely connected with my work.
Participants of my study were consumers who buy Tokay „aszú” mainly in shopping centres, supermarkets and low-price shops specified for wine selling. Wine shops have important roles as they give opportunity for salespersons to make closer relationships with buyers. These shops could be communication channels of spreading wine culture. It would be favourable if in every town or city there were at least one wine shop giving the opportunity of consultation besides commercial activity and also providing services that support the improvement of wine culture’s position. The majority of questioned people spend less than 4.000 Forints on buying of Tokay „aszú” in a year. Results of the questionnaire survey support the fact that there is a demand for these wine-specialities, but lack of money strongly effects demand.
The Following summarises the history of Tokay wine, tasks of Hungary and the expected effects relating to EU-accession. Regulation of oenology and the wine-market, referring to quality wines and main results of the survey are also overviewed in the text. -
Economic questions of maize production on different soil types
289-292Views:106The requirements and objective of cultivation are in constant change. For example, different cultivation systems are developed for the purpose of soil protection, the preservation of its moisture content and on soils with various precipitation supply or production site conditions. Traditionally, one of the most important cultivation aims is crop needs. Further cost saving in fertilisation and crop protection can only be achieved by reducing the quality and quantity of production or it cannot be achieved at all. Furthermore, the costs can be significantly reduced by means of the rationalisation of cultivation. Energy and working time demand can also be notably reduced if ploughing is left out from the conventional tillage method. The key requirement of economicalness is to perform the cultivation at the optimal date, moisture level and the lowest possible cost.
Within production costs, the cost of cultivation is between 3–17%, while they are between 8–36% within machinery costs. It is the vital condition the usability of each technological method to progressively reduce costs. Our evaluation work was carried out with the consideration of the yield data obtained from cooperating farms and the experiment database of the Institute for Land Utilisation, Regional Development and Technology of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen. Three technological methods (ploughing, heavy cultivator and loosening tillage) were used on several soil types which differ from in terms of cultivability (chernozem, sandy and sandy clay soils) from the economic/economical aspect. We examined the sectoral cost/income relation of maize production as an indicator plant. The maize price during the analytical period was 45 thousand HUF per t. On chernozem soils, the production of maize can be carried out on high income level, while maize production on sandy soils has a huge risk factor. The role of cultivation is the highest on high plasicity soils, since they have a huge energy
demand and the there is a short amount of time available for each procedure in most cases. -
Study on the cold tolerance of maize (Zea mays L.) inbred lines in Phytotron
41-45Views:73Maize has come a long way from the tropics to the temperate zone. In the beginning, the spreading of maize was prevented by its sensitivity to cold. Improved cold tolerance at germination is one of the most important conditions for early sowing. The advantage of cold tolerant hybrids is that they can be sown earlier, allowing longer growing seasons and higher yields, due to the fact that the most sensitive period in terms of water requirements, flowering, takes place earlier, i.e. before the onset of summer drought and heat.
In Martonvásár, continuous research is carried out to improve the cold tolerance of maize. In the present experiment, the cold tolerance of 30 genetically different maize inbred lines was investigated in a Phytotron climate chamber (PGV-36). The aim of our research is to identify cold tolerant lines that can be used as parental components to produce proper cold tolerant hybrids and/or as sources of starting materials for new cold tolerant inbred lines. After observing and evaluating changes in phenological traits under cold-test, the results of the cold-tolerance traits of interest have been used to highlight several inbred lines that could be good starting materials for further research on genetic selection for cold tolerance.
