Population date of Great Cormorant at the area of the Hortobágy Fish Farm Co.
51-54Views:269Hungary’s great cormorant stock did not use to be a considerable one before the 1980s. After that, their number has been rising significantly. The size of the stock now is rather stagnating or slightly growing. The presence of cormorants has been significant around ponds of the Hortobágy Fish Farm in the past few years. Due to considerable fish consumption of cormorants it is essential to know which and what kinds of units of the ponds (spawning, supply, and market) are preferred by the birds in order to see to adequate protection. The aim of our research was to discover any differences in the number of cormorants present at particular units of the fishpond system and certain ponds of equal kinds within them.
Our observations were in line with the methods used in ornithological researches. The experiment took place between April and October 2012 on a monthly basis. According to the results we found relevant differences in the number of cormorants based on the seasons and months as well. This fact was supported by statistical data. During the autumn and winter birds prefer supply and market purpose ponds while their presence here is vanishing during the summer. Relevant presence of cormorants around the area of the Old Fishponds (70 to 200 specimens) might be due to lack of disturbance and large sizes of the ponds.
Our research has great scientific relevance since it is vital to be aware of the preferred periods and areas in order to maintain effective protection; this way alerting activities can be applied in a more harmonized way. By keeping our research up as a monitoring activity, we will be able to receive more precise data later on.

Research of different adjuvants and yeast dosages in honey fermentation process
5-7Views:153In order to ferment honey it is necessary to add in the fermentation environment some substances with the role of adjuvants, to improve the honey must composition and to help the fermentation process. There were tested 2 different combination of adjuvants which were analyzed in the fermentation process. Also the physical and chemical properties of the final products were analyzed. After establishing the most suitable mix of adjuvants it was necessary to test the right dosage of the yeast used to metabolized sugars: Saccharomyces cerevisiae, in order to obtain appropriate organoleptic properties.

Analyzing the Population Retaining Ability and the Ability to Economically Provide for a Population in the Micro Region of Püspökladány
210-219Views:83According 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. -
Economic Assessment of Biodiesel Production for Hungarian Farmers
72-76Views:88Utilisation of oil of plant origin as a fuel is gaining acceptance in the European Union and elsewhere. Besides environmental protection, energy saving, and decreasing over-production of food. Additionally, the subsidisation of farmers and the development of rural sub-regions also contribute to its spread. This study specifically focuses on the direct effects biodiesel's raw materials and final products are now having on farmers, while reviewing and quantifying these effects. I have purposely restricted my analysis to these two elements of the biodiesel chain.
The biodiesel chain seems to be a great method for improving the economic and social position of participant farmers in many ways. Presently, the profitability of raw materials’ production looks to be the crucal point in the chain, and could be strengthened best with intensive, habitat-specific agrotechnic. It would only be possible to reach a favourable profit margin for farmers if yields reach unrealistic averages or if there is a significant hike of the 2000 producer’s price in the oil plant branch.
The main attraction of sunflower- and oilseed rape production lies in the stabilization of market conditions, which is not only gong to appear in oil plant branch but – thanks to the reduction of outputs – also in the cereal branches. Better economic safety for farmers may play a role at least on the same level as in plant production, which involves more risks than profit maximalization.
The reduction of the prime cost of biodiesel could be possible through the direct combustion of the whole oilseed plant or its residues or electricity production using them. Whereas energy demand for biodiesel production is low (appr. 5%) but it needs subsidization and the prices of natural gas and electrical energy presently look favourable in Hungary. Additionally harvesting and baling of the residues is technically problematic, which is why their use may seem to be reasonable just over the middle or long term. Another possible factor of cost reduction could be the centralization of some partial operations, which needs serious financial resources to reduce amortization cost per product, provided there be several biodiesel projects near each other during establishment. Creation and operation of a logistical system could also be a good method for improving the viability of the biodiesel chain, in order to optimize transport schedule and distances. However there are also some organizational difficulties in this case. -
Evaluation of Soil Degradation Based on High Resolution Remote Sensing Data
145-148Views:104Soil salinity is the main problem of soil degradation in the Grate Plain with cultivated area of 20% affected. Its influence is accelerated on the water managed and irrigated lands. Remote sensing can significantly contribute to detecting temporal changes of salt-related surface features. We have chosen a farm where intensive crop cultivation takes place as a test site as soil degradation can be intensive as a result of land use and irrigation. In order to evaluate soil salt content and biomass analysis, we gathered detailed data from an 100x250 m area. We analyzed the salinity property of the samples. In our research we used a TETRACAM ADC multispectral camera to take high resolution images (0,2-0,5 m) of low altitude (300-500 m). A Normalized Vegetation Index was computed from near infrared (750-950 nm) and red (620-750 nm) bands. This data was compared with the samples of investigated area. Analyzing the images, we evaluated image reliability, and the connection between the bands and the soil properties (pH, salt content). A strong correlation observed between NDVI and soil salinity (EC) makes the multispectral images suitable for construction of salinity map. A further strong correlation was determined between NDVI and yield.

GC-MS studies to map mechanistic aspects of photolytic decomposition of pesticides
11-16Views:99Transformation of pesticides in the environment is a highly complex process affected by different factors. Both biological and physical-chemical factors may play a role in the degradation, whose ratio depends on the actual environmental conditions.
Our study aims to reveal specific details of photolytic degradation of pesticides as important soil contaminants. Significance of these studies is enhanced by the fact that pesticide decomposition may contribute to soil degradation, and have harmful biological effects by degrading to toxic products. The toxicity of the examined pesticides is well known, however very little information is available regarding their natural degradation processes, the quality, structure and biological impact of the degradation products.
The photolytic degradation of frequently applied pesticides of distinctive types (acetochlor – acetanilide, simazine – triazine, chlorpyrifos – organophosphate, carbendazim – benzimidazole) was investigated. A special, immerseable UV-light source was applied in order to carry out photodegradation. The degradation processes were followed by thin layer chromatography (TLC) and mass spectrometry coupled with gas chromatography (GC/MS). EI mass spectrometry was used to identify the degradation species.
Each of the studied pesticides underwent photolytic decomposition, and the detailed mechanism of photolytic transformation was established. At least four degradation species were detected and identified in each case. Loss of alkyl, alkyloxy, amino-alkyl and chloro groups might be regarded as typical decomposition patterns. Deamination occurred at the last stage of decomposition. -
Correlation between cultivation methods and quality in some vegetable species
313-317Views:150Quality 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. -
The setting of fenological-stadium of plum (Prunus domestica) rootstock-variety combinations in 2011–2013
25-29Views:120We planted experimental trees, namely 6 plum varieties and 6 plum rootstocks in the spring of 2010, which of aim were the phenological -phases of variety-rootstock combinations analyses.
We observed 18 plum varieties – rootstocks combination in Kecskemét, in Garden of Kecskemét Collage. We set the examination with 2 kind irrigations. A plum combination appear in the examination in 6 repetition depend on irrigation. The vegetative period started bursting of buds in 2011 March 15–18.; 2012 March 16–19. and 2013 March 12.–April 2. This was followed green buds stadium shorter or longer periods, than appeared white buds stadium and in the following day we could see started of flowering. The main flowering kept 7–10 days, except in 2012, when arriving frozen by April 8. morning stopped the main flowering. Following flowering we observed fruit falling 3 occasion, these weren’t noticed calendar date. These were in order: fruit falling after set, fruit falling in June, fruits falling before harvest. In 2013 these fruit falling there weren’t considerable. The ripening was characteristically varieties. The most of earlier ripening was ‘Katinka’/‘St Julien A‘, from which we didn’t harvest in 2011, but in 2012 July 17, and in 2013 July 9. pick up some plum fruits. The ‘Cacanska lepotica’ ripped in July 21–30, this was followed in ripening time the ‘Topfive’ in July 19.–August 6., The ‘Toptaste’ in August 5–23., The ‘Jojo’ in August 2–26., and the ‘Topper and ‘Katinka’/‘Mirobalan ’ stopped ripening in August 22.–September begin. The colouring leaves and the falling leaves started continue after harvesting, but we experienced the end of the falling leaves in the first bigger frozen time, October 24.–November 26.

Estimation of direct and maternal genetic parameters for weaning weight in Hungarian Simmental cattle
17-22Views:175The aim of the current research was to estimate variance components and genetic parameters of weaning weight in Hungarian Simmental cattle. Weaning weight records were obtained from the Association of Hungarian Simmental Breeders. The dataset comprised of 44,278 animals born from 1975 to 2020. The data was analyzed using the restricted maximum likelihood methodology of the Wombat software. We fitted a total of six models to the weaning weight data of Hungarian Simmental cattle. Models ranged from a simple model with animals as the only random effect to a model that had maternal environmental effects as additional random effects as well as direct maternal genetic covariance. Fixed effects in the model comprised of herd, birth year, calving order and sex. Likelihood ratio test was used to determine the best fit model for the data. Results indicated that allowing for direct-maternal genetic covariance increases the direct and maternal effect dramatically. The best fit model had direct and maternal genetic effects as the only random effect with non-zero direct-maternal genetic correlation. Direct heritability, maternal heritability and direct maternal correlation of the best fit model was 0.57, 0.16 and -0.78 respectively. The result indicates that problem of (co-)sampling variation occurs when attempting to partition additive genetic variance into direct and maternal components.

On the Knowledge of University Students About the Strategies of National Sustainable Development
232-240Views:104The definition of sustainable development has a past which spans two decades. Today it is evident that the three pillars of sustainable development – environment, economy and society – have a strong correspondence and equally effect on every people. The UN’s Environment and Development Conference in 1992 declared the requirement in the document of Objectives for the XXI. century, that governments should prepare national sustainable development strategies. The World Conference of Sustainable Development in August 2002 made a stronger decision: „the states should make immediate steps forward … defining and preparing their national sustainable development, and for the purpose to start its realization until 2005”. Most of the countries fulfilled these requirements, and the Hungarian government promises to prepare its national strategy by the end of 2004.
The aim of my study is to survey the knowledge of university students about the above mentioned process and generally about the topic of sustainable development. The selection of the target group is justified by the importance of young intelligentsia in the future. In order to examine their knowledge, I prepared a questionnaire and from the emerging primary data, my conclusion and statements have been deducted by a processing-analysing course, on the bases of which I made my suggestions. -
Gene Bank Developed by Induced Mutation for Selection
45-49Views:91Heterosis breeding in maize caused gene erosion by using uniform inbred lines. In order to strengthen the genetic base, we established a gene bank containing lines with broad genetic variability, resistance and adaptability. The maize gene bank is a result of our work in the past two decades.
The gene bank originated from treatments of maize seeds of hybrids and inbred lines with fast neutrons. The 1500 maize lines have great genetic variability which can be exploited after strict assessment and selection. As a result of the past several years, P 26, P 61 and P 62 lines have been released after DUS investigation in 2001. -
The zooecological remediation of technogen faulted soil in industrial region of Ukraine steppe zone
111-115Views:87In Ukraine’s Steppe zone the extraction of minerals is important. To eliminate the consequences of coal mining the agricultural recultivation of the disturbed soil is used. Thus toxic compounds for human beings and the majority of plants and soil biota representatives, which can be found mining rock, get into plants and invertebrates by trophy chains. When remediating soil, it is necessary to create tropic conditions in order to provide the life of soil biota. Earthworms (Lumbricidae) are the primary decomposers of the organic material. They are numerous in soil and facilitate the improvement of natural and artificially created soil. This paper studies the possible influence of different variants of substrates, which are used in re-cultivation, the leaf litter from leaves of different wood species, as well as different levels of humidity on the representatives of soil saprophages. Optimal variants of artificial mixed-soil providing the stable existence of animals have been shown, which are recommended for the implementation of rehabilitation measures.

Developing vegetable and fruit marketability potentials in Hajdu-Bihar county in terms of Hungary’s EU accession
60-69Views:92prearrangement, Hungary will be ready to join the EU by the 1st of January 2003. In the course of negotiations, the Government places special emphasis on agriculture, because Hungary is an agrarian country. Agricultural production is an important economic factor in Hungary: larger a factor in its economic structure than in those of the present EU member-states. In order to preserve competitiveness, Hungarian farmers and its
processing industry require information on the EU's CAP and other market influences.
In Hajdú-Bihar county the quality of agricultural products fall behind the standards of the European Union. There is no real solidarity among farmers, so they are left alone and are unable to meet higher, those standards, which were introduced by the structural changes of the market. Unfortunately, there is only one fruit and vegetable marketing organization (PO) in the county, although its necessity and effectiveness has been proved several times.
Within the framework of Rural Development, agricultural marketing is vital, because together with the local FVM institutes, it can help the farmers by providing consultation, information, and by marketing their products. Since fruit and vegetable growing has a considerable history in Hajdú-Bihar county, marketing activities can be effective in assisting both the farmers and the processing industry in preparation for EU integration. -
From the Concept of Sustainable Development to the Subsidies of Agricultural Environmental Management
354-361Views:86The most important aim of the study is to introduce the theoretical background of my PhD dissertation – agricultural environmental management –, in order to help the scientific foundations for my dissertation, which is in progress. For this reason I will try to clarify and systematize facts found in the special literature according to my own thoughts, from a new aspect.
In my study, I therefore attempt to introduce the theoretical background of sustainable development as pertains to the subsidies of agricultural environmental management (National Agricultural Environmental Management Program, National Regional Development Plan, agricultural environmental management measures). Having clarified the concepts I place sustainable development in the economic theories directed to the treatment of environmental problems, introduce where subsidies are within the environmental regulation implements and I dwell on to the institutional questions in the explanation. I then study questions of sustainable agricultural economics. Accession to the European Union has to be considered as one of the most important concrete motivities of domestically coming into prominence of agricultural environmental subsidies therefore I think it is important to study how the problematic of sustainable development, sustainable agricultural development and agricultural environment protection worked out in the EU. Finally I survey the main characteristics of domestic agricultural environment management programs fitting into the theories explained above, how the program adjusts to the theories of sustainable development and sustainable agricultural development.
In the dissertation I begin with sustainable development as the broadest theoretical background, then I survey a narrower category, the theories of sustainable agricultural development and how concrete agricultural environmental programs fit into the studied theoretical relations. -
Information and Communication Technologies in tourism
49-53Views:173Technological progress and tourism have gone hand in hand for years. Information communication technology (ICT) and tourism are two of the most dynamic motivators of the emerging global economy. Tourism can be considered as one of the most profitable sectors of the Hungarian economy, and in rural areas it is often the only successful economic activity.
Development of ICTs and the expansion of the Internet have changed dramatically in the past few decades. This process is noticeable in
Hungary, as well. Platform of tourism increasingly get to the Internet nowadays, which is vitally important because tourism is an information-intense industry. Therefore, it is critical to understand changes in technologies in order to maintain the crucial role of this sector in the Hungarian economy.
The aim of my study is to support the significance of tourism in Hungary and especially in the North Plain Region with the help of statistical data. Then, I try to show how ICTs appear in this sector and emphasize the role of these tools with some concrete examples. -
Production and economic risk analysis of pig fattening
171-176Views:133I prepared a “model farm” producing fattening pigs in order to examine the main risk of production and market factors affecting the profitability of fattening pig production. Values of body weight (at the beginning of fattening and at the end of fattening), mortality rate, feed conversion ratio (FCR) of fattening pig as well as the main cost and price data were recorded as the input data of the model. Production value per unit, production cost per unit and income per unit were used as output. The Monte-Carlo simulation was used in the model for risk assessment. Based on the results of the analysis, it was concluded that the production value per unit was most affected by the selling price of fattening pig (ß=0.972), the production cost per unit were most influenced by the body weight at the beginning of fattening (ß=0.567) and the feed conversion ratio (ß=0.537), in addition, the change of the income per unit was most determined by the previously factors.

Comparative analysis of inoculated soybean in extinguishing soil
113-116Views:249In order to achieve higher yields, better technological methods offered in the current market, which aims to help the producers in the realization. To guarantee good yield because more and more people try with a variety of products, but you have to make the expected impact falls short.In this experiment, the following results were obtained: the soil suspension closely related to the inoculum of seed or seed treatment,which affects the soybean nodule formation, core saturation, and yield and protein-oil indicators. The soil suspension composition may exert positive and negative effects, which depend on how bacterial strains inoculum combined on the soybean seed surface. It is shown in our experiment very well, that between inoculum and inoculum as well as inoculum and seed treatment materials may be antagonism which setback to the soybean nodules formation and the yield, but not worsen the protein-oil indicators.

Unfair commercial practices towards consumers in the Hungarian food industry
67-71Views:68Unfair commercial practices in the food industry can include actions and practices by traders or producers that mislead consumers about the true characteristics, quality, or price of products. For example, if a producer does not accurately and transparently list the composition of products, or if advertisements contain false or misleading information about products, or if inappropriate product quality is concealed, or if promised benefits of products are not realised, or if consumers are unfairly persuaded to purchase products.
It is important to note that all traders and producers must comply with consumer protection rules. If any unfair commercial practices are observed, consumers can legitimately file a complaint with the Consumer Protection Authority or the Hungarian Competition Authority.
Unfair commercial practices can be a serious problem for consumers as they mislead them about the true characteristics of products, making it difficult to make informed purchasing decisions. Therefore, it is important for consumers to be informed about the true composition and quality of products in order to avoid falling victim to unfair commercial practices.
Through various legal cases, I demonstrate how important it is for consumers to be fully informed and aware of their rights. Additionally, I illustrate how investigating different complaints can have an impact on preventing unfair commercial practices.

L’incubation et l’éclosion des oeufs des vers à soie de chêne Antheraea pernyi Guer (Bombycidae)
61-63Views:68In this paper we studied optimal conditions which need to be fulfilled in order to have successful incubation and hatching of eggs of the species Antheraea pernyi Guer.
The incubation of the eggs of this species implies a proper environment: temperature of 18-21oC, relative humidity of 80%, unvarying light, aeration 2 or 3 times a day and a density of 50 g eggs for a 20/50 cm area.
In these conditions, the incubation of the first generation lasts 10-12 days and of the second generation up to 8-10 days. The second generation needs higher temperatures (22-26oC) and higher humidity (optimal value 90%).
In this species, hatching lasts 6-7 days, with a maximum during the second day; it takes place especially early in the morning. -
The effect of the plant density for the yield of the maize hybrids
50-61Views:111In order to enchance the yield stability of maize, the effect of plant density on yields was studied on a typical meadow soil in Hajdúböszörmény between 2002-2004. In the plant density experiment, we used the method of Béla Győrffy. The plant densities applied therefore 20 to 100 thousand plants/ha by ten thousand scale. The application of fertilizer rates for the maize hibrids in every year were N: 110 P: 90 K: 120 kg/ha. We used a manual soiling-gun in the experiment. In every year we used plant protection techniques against monocotyledonous and dicotyledonous weeds. The harvest was done by hand. The facts were read by variancie analysis and linear regression analysis. The moisture and the temperatures were extreme in 2002, 2003, 2004. We have to mention defficiery of moisture in 2003 which is shown that the hot days number increased. After evaluating our findings we can conclude that most hybrids showed a significant correlation between increased plant density and the volume of yields. On the basis of the experiments we divided the hybrids into four groups: the first group included the hybrids suitable for increased plant density with a wide range of optimal density values; the second group included hybrids, which did not require high plant density, were capable of good individual performance and tended to grow several ears; the third group included flexible corn types, which grew longer ears in favourable years, thus yielded more; and the fourth group included the hybrids, which were sensitive to increased plant density and which showed a narrow range of optimal density values. Finally, plant density determines the yield; we have to consider optimal plant density intervals as well as optimal plant density, and we also have to place a high emphasis on the use of hybrid-specific technologies.

CO2 emission of the soil on barley stubble
95-102Views:143In the last decades the physical and biological status of the soils in Hungary significantly decreased. The degree and intensity of CO2-production of the soil is in close correlation to its structural status and organic matter content. In a complex soil tillage experiment at Karcag in situ measurements have been carried out since 2002 in order to determine the CO2-emission of the soil. Carbon-dioxide emission of the soil in the cases of conventional tillage and reduced cultivation system was analysed in a long-term cultivation experiment. The measurements were carried out after the harvest of the barley, thus root respiration was excluded. For the spatial delimitation of the measuring area a newly developed frame+bowl set was used. Based on measurements, significant differences between cultivation systems can be recognized due to the soil structure changes and its effects

Connections between the roma segregation processes and home circumstances in the outskirts of Hajdúböszörmény
57-61Views:106In order to analyze the social status of local gipsies – both inside the community and among themselves – we conducted an empirical research of 300 participants, in which we took the distinctive spatioand sociostructural features of Hajdúböszörmény into consideration. Furthermore, a second research was also carried out in which we questioned 25 prominent persons. Participants were selected in a way that the study may give a realistic picture of each of the segregated areas of the town (focusing on social, educational and realty issues), thus besides questioning professionals dealing with the concern of gipsies on a daily basis, we decided to involve representatives of the local government as well. The reports concerning the realty status of the segregated areas were supplemented with further material provided by the local government.

Economicalness of self-propelled work platforms in superintensive apple plantations
91-98Views:131The main goal of this study was to determine whether the use of work platforms in super intensive apple orchards in order to reduce production costs and enhance work area performance under Hungarian circumstances an economic investment is. The analysis was carried out using a deterministic simulation model based on primary data collection from apple producing businesses. The results show that work platforms have remarkable economic advantage in case of operations with high machine work expenditures or where they significantly improve the area performance of manual labour. The former was due to the much lower operating costs of work platforms compared to tractors, while the latter comes clear from reduction of manual labour input per hectare. The greatest economic advantage of work platforms occurs in case of harvesting and pruning, but in case of other operations they have no significant cost advantage. They main economic disadvantage is, however, that apple breaks more when harvesting with work platforms, i.e. picking quality deteriorates significantly. It can be concluded, that purchase of work platforms cannot be considered economic investment under Hungarian circumstances. It might be economic, utilised on maximum area (ca. 30 hectares) by certain companies in special cases, but in most cases has no favourable payback conditions.

Mitigation of the effect of secondary salinization by micro soil conditioning
115-119Views:226This research has the general goal to meet the customization of agriculture in small scale farming. We are developing a technique using micro doses of soil conditioners and organic material applied in the root zone of vegetable crops. We expected to change the physical and chemical properties of the affected soil, which has been irrigated with salty water. Two different soil conditioners were tested. A lysimeter experiment including 8 simple drainage lysimeters was set up in the Research Institute of Karcag IAREF University of Debrecen in 2017. The main goal was to study the effect of different soil conditioners on the soil endangered by secondary salinization induced by irrigation with saline water. In order to compare the difference between the treatments, we collected soil samples, water samples, and determined the yields. Chili pepper (Capsicum annuum) was used as an indicator crop during one specific agricultural season. The technique called micro soil conditioning is rational because several reasons. The roles of the technique are various, for example it can serve as a source of carbon or a container for soil amendments and can minimize evaporation. We found this technique not to interfere with the chemical reaction or the interaction with the plants. However, the micro doses of soil amendments had the role to minimize the risk of soil degradation and do not significantly influence soil respiration. In addition, by improving soil properties, soil conditioning increases the leaching of the excess of salts from the root zone. In fact, this technique can decrease the cost of the inputs and improves the production of vegetables, and at the same time mitigates the effect of secondary salinization.

Career Monitoring, Institutional Assessment and Ranking
73-77Views:107The labour market started to make a difference between the diplomas issued by higher educational institutions. The decision of prospective students considerably depends on the labour market value of a certain diploma. Career monitoring of graduates is a very important task of higher educational institutions. Feedback and experiences from the graduates and the employers are valuable sources of information for the institutions to shape their teaching activities in order to meet the actual demand of the labour market. Career monitoring of graduates is not a common activity at present in Hungary. Some institutions regularly monitor the labour market position of their graduates, but unfortunately most institutions do not invest time or manpower in such activities. A country level study has already been introduced that included almost all the higher educational institutions in Hungary. This study, coordinated by the Hungarian Ministry of Education, appears ready to be continued. The aim of this study is to introduce some institutional and country level initiations of career monitoring.
