Stand evaluation, crop estimation and yield analysis of winter wheat for the optimization of yields
103-109Views:125The authors have been carrying out stand evaluation, crop estimation and yield analysis in winter wheat since 2012. The sampling areas were assigned at the fields of the Training Farm of the Faculty of Agricultural and Food Sciences of Széchenyi István University Mosonmagyaróvár according to the structure of the cropping system. According to their observations the value of field emergence is always lower than the laboratory germination. The weak emergence is important because the lower plant density cannot be compensated by the increased tillering in spite of having larger plant growth space. It is proven by the fact that they detected strong productive tillering even at 5 and 10 mm plant spacing while there were single-spiked plants at 40-50 mm plant spacing as well. The analysis revealed that the total ear mass and grain mass of wheat plants bearing two or more ears is almost the double than that of the single-spiked plants. It was a further basic experience that the largest ear of ”multiple-spiked” plants is always heavier than the single ear of one-spiked plants. Plants with intense tillering and more ears demonstrate the importance of proper seedbed preparation and drilling and the significance of sowing good quality seeds. These are the factors that determine field germination and emergence, influence the speed and intensity of initial development and by all these factors the sufficient productive tillering. The authors emphasize the use of exact and objective methods at crop estimation, e.g. the relationship between the ear mass and the yield which is in strong correlation whilst ear length and grain mass are not suitable for a precise estimation. The authors conclude that crop estimation and yield analysis must be inevitable tools of modern crop production and will be particularly important in precision agriculture. These tools also qualify the job done by farmers and helps to identify the areas that require special attention.

Agronomical and economic evaluation of various cultivation systems on meadow soil
103-106Views:102The requirements and objectives of cultivation are in constant change. There are different cultivation aims if the objective is soil protection, the prevention of its moisture content or on areas with different precipitation supply or production site endowments. Based on the experimental database of the Institute for Land Utilisation, Regional Development and Technology of the University of Debrecen, Centre for Agricultural and Applied Economic Sciences and the KITE Plc., the various cultivation systems in Hajdú-Bihar country were examined with maize as indicator plant. The sample area can be found in the outskirts of Biharnagybajom on meadow soil. On the examined plot, spring strip basic cultivation, loosening and autumn ploughing were applied on 15-15-15 ha, respectively. At the time of taking undisturbed soil samples, soil conductivity measurements were also performed with a Penetronik penetrometer. Undisturbed soil samples were taken from each treatment before sowing (on 5th April 2012). The yield obtained in the strip cultivation treatment increased that of the ploughing and the loosening technology. The economic indexes are the most favourable in the strip cultivation.

Fish consumption of the great cormorant in the area of Hortobágy Fish Farm
81-84Views:125The cormorant (Phalacrocorax carbo) is a bird species that nests sporadically but in colonies, besides larger fishponds and rivers in Hungary. The number of its individuals has been increasing during the last two decades. The species eats solely fish, therefore it can cause serious depredation of the fish stocks in fishponds of intensive system and after the freezing of the ponds, in larger rivers, which are not yet frozen. The aim of our research is to reveal the damages the birds can cause on the studied areas and the extent of the losses the Hortobágy Fish Farm Co. has to realize.
Our studies were carried out between April 2012 and November 2013. During cleaning, the investigation of the crop contents of the birds and their biometric studies were conducted. The results revealed the diverse nutrition base of the species. In the samples, we have determined 300 identified fish individuals; in 289 cases, the exact fish species were determined, too. Although statistical differences were found between the given pond unit and the consuming of the corresponding fish species (P=0.05% beside), this cannot be considered as absolutely certain.
Our investigation is of considerable significance in terms of nature preservation and not least, it has substantial financial concerns too. Under the ever harder fish production conditions, the presence and thus the permanent nutrition of the bird affect the fishermen. In favour of the maintaining of the natural ecological balance and the income of the fishers, the elaboration of adequate protective and efficient preventive processes will be necessary in the near future.

Variability examination of photosynthetic pigment content and specific leaf area in individual maize (Zea mays L.) plants
153-157Views:204Currently, maize is one of the most important crops (Zea mays L.) both globally and in Hungary. We compared physiological parameters of a maize genotype – p9903 – at two different experimental sites in a field experiment. Furthermore, we examined these parameters’ variability in individual plants on the leaves with different ages. Absolute chlorophyll content of the leaves were analysed, separately that of chlorophyll a and chlorophyll b. We also measured the absolute carotenoid contents of leaves. Furthermore, we calculated these photosynthetic pigments’ content ratio. Specific leaf area (SLA) and dry matter weight were also measured in order to characterise plant production. The results obviously reflect the decreasing in the efficiency of photosynthetic apparatus on the low yield site. Otherwise, we identify significant differences only in certain cases of leaves.

Sensitivity of maize hybrids to common smut under field artificial inoculation conditions
25-28Views:188Common smut disease of maize is one of the most frequent diseases of crop. In the last decades the importance of disease has decreased in feeding maize production, however its importance increasing again nowadays, especially at sweet maize hybrids. The aims of this work was to find hybrids possess of resistance, and to evaluate which ones are more or less susceptible under field artificial inoculation circumstances. Among feeding maizes the less susceptible hybrid was ‘P9578’, and the most susceptible ’NK Columbia’ hybrid, and differences in cob infection between them was significant (8.8%). At sweet corn hybrids the less susceptible was ’Prelude’, while the most susceptible was ’Jumbo’ with very high significant 74.6% differences.

Investigation of the effect of allithiamine-enriched feed on the poultry gut microbiome composition and resistome
149-155Views:66Over the past 20–25 years, the poultry industry has evolved into a specific protein production system. However, the stress resulting from intensive rearing practices has led to numerous negative consequences, making the optimisation of livestock gut microbiome composition crucial for mitigating these effects. Advancements in modern molecular biology methods have brought attention to the impacts of nutrients on gut microbiota. In our study, we extensively investigated the changes induced by feed formulations rich in phytonutrients on the gastrointestinal microbiota of livestock using targeted 16S rRNA amplicon sequencing. Our objective is to examine how the developed feed prototype affects the composition of core microbiomes in raised poultry, community diversity, and the resilience of complex microbial networks. We seek correlations between biological livestock and environmental samples to identify which community constituents, in what proportions and occurrences, may play a role in the development of specific diseases. Based on our measurement results, it can be asserted that allithiamine positively modulated "beneficial" community constituents. Beyond the impact of allithiamine-enriched feed rich in phytonutrients, the composition of the microbial community in the poultry gastrointestinal tract is significantly influenced by the age of the birds. Furthermore, due to the presence of multi-drug-resistant pathogens in environmental samples from livestock facilities, appropriate transmission risk management measures are of paramount importance.

Developing vegetable and fruit marketability potentials in Hajdu-Bihar county in terms of Hungary’s EU accession
60-69Views:78prearrangement, 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. -
Effects of Site on Winter Wheat Quality 2002/2003
100-107Views:94The demand of modern societies for high food quality is evident. Thus, it is important for agriculture to produce row materials that are valuable for nutrition and have favourable characteristics for food processing. For this we need a knowledge about the factors which determine the quality of products. One of the main features of plant production is the “immobility”. This way the characteristics of the field influence the quality of the product, like example winter wheat, which is the main cereal in Hungary and Europe.
The Concordia Co. has charged the Central Laboratory of Debrecen University, Agricultural Centre with laboratory testing of the 2002/2003 winter wheat crop. The samples consist of thirteen winter wheat varieties from six different sites under the same cultivating conditions. Therefore, the important wheat quality factors were analysed solely against site conditions with the use of Győri’s “Z” index, which contains these parameters.
Soils were tested first. In this experiment excepting the negligible differences between the sites, there were no linear relations found between quality factors, productivity and soil features. The case is the same with the relation between precipitation, temperature and quality parameters. However, it must be noted that additional soil analyses are required to interpret the extreme results obtained from Karcag.
The calculated Győri’s Z-index shows relative stability concerning certain varieties, although considerable deviation can be found in varieties related to the sites. According to these results, it can bestated that winter wheat quality was not linearly influenced by soil and weather in the 2002/2003 vegetation period. As the same cultivation technology was used in the experiment, the index was determined by genetic features. It must be noted that these findings are relevant only to this experiment. -
Present situation and future prospects for Hungarian fruit and vegetable sector
31-38Views:71Changes in people’s lifestyles and the emergence of nutritional science have created favorable opportunities for a boom in fruit and vegetable consumption, which have been fully exploited by the adaptive fruit producer and exporter countries. Unfortunately, Hungary is not one of these countries. Affected by a number of uncertainty factors, the Hungarian fruit and vegetable sector has fallen behind international trends, seeking opportunities for survival (Erdész, 2007).
The impacts of the country’s accession to the EU have been more adverse than expected. While no administrative measures are used to control production and the increasing competition and import have put Hungarian producers to a loosing position. The cooperation producers, the well-organized work of professionals and the coordinated activity of producers marketing organizations may resolved some of the problems affecting the sector.
The fruit and vegetable sector can also anticipate significant changes during the new seven-years budget period of the CAP reform.
With the new drat reform of the sector, the European Commission intends to simplify the common organization of the fruit and vegetable market, improve competitiveness, increase market orientation, promote fruit and vegetable consumption and to continue the environmental efforts.
Hungary has had great expectations concerning the reform of market regulation, but the Commission proposal didn’t bear out the expectations, because the new proposal includes insignificant changes in important issues and fails to provide sufficient additional resources for the catching up of he new member states. -
The R&D and innovation activity of agribusiness enterprises in Hajdú-Bihar County
67-71Views:125Economic changes have significantly accelarated in the 21th century. In this turbulent market environment enterprises are forced to adapt continously as they must be flexible in order to meet changing market needs. To achieve flexibility companies require innovation. The economic relevance of innovations is significant in every market sector and agriculture is no exception. Re-dynamizing agricultural innovations is a possibility for the outburst of the Hungarian agriculture. Agricultural enterprises have to face competitors as well and they should give priority to efficiency, sustainability and competitiveness in order to preserve their position in BOTH global and domestic markets. This study examines the innovation potential of the agricultural enterprises in the North Great Plain region based on own databases and case studies.

The parameters of homemade jams after storage
39-42Views:135Nowadays producing jams is considered a traditional way of plum processing in Hungary. Plum jams without added sugar can be stored
This research aimed to analytically determine which quality parameters of the jams and to what extent they change during storage. Furthermore, this study intended to find out whether a concious consumer can presume any difference between varieties or the year of harvest, or wheather a one-time customer should suspect differences in quality parameters of the different products. This study focused on those differences or alterations in the parameters that occur in the jams made from several different plum varieties produced in different years.
I analyzed the classic chemical parameters (dry matter content and ash content) and physiologically important nutritional components (phenolic and flavonoids antioxidants and vitamin C). In this research I used jams which were produced from 6 varieties grown in 2009 (President, Tophit, Bluefre, Elena, Presenta, Stanley), 4 varieties from 2010 (President, Bluefre, Elena, Presenta) and 6 varieties from 2011 (President, Tophit, Bluefre, Elena, Presenta, Stanley). Jams were produced with traditional technology in cauldrons without added sugar. Jars were placed into a relatively dark and cool place and were stored there until the analysis.
Having regard to the results, when consumers choose between the different products they also choose quality since the processed plum variety, and the year of production/processing determine the nutritional value of the specific product. This could be used for market positioning and promotion of the product, however further research is needed to gain more information from the differences that derive from the varieties, year of harvest or other factors. This way fruit and jam producers could turn these informations into market advantage.

Evaluation of chickpea (Cicer arietinum L.) in response to salinity stress
105-110Views:199Soil salinity is a severe and expanding soil degradation problem that affects 80 million ha of arable lands globally. Chickpea (Cicer arietinum L.) is very sensitive to saline conditions; the most susceptible genotypes may die in just 25 mM NaCl in hydroponics. Approximately 8–10% yield loss in chickpea production is estimated due to salinity stress. However, it is still not established why chickpea is so susceptible to salt affection. Salinity (NaCl) impedes germination of seeds, though chickpea varieties considerably differ from one another in this respect. Some chickpea genotypes are more tolerant in the stage of germination, tolerating even 320 mM NaCl. The reasons of this variation are unrevealed; there is a shortage of knowledge about the germination abilities of chickpea genotypes in saline conditions. Nevertheless, the effect of salt stress on vegetative growth can be analysed in hydroponics, in pot or field conditions, regardless the experimental environment, the ranking of genotypes regarding salt resistance is coherent. Chickpea genotypes can be different in their ability to retain water, maybe under salt affection; the more salt tolerant lines can maintain higher water content in the shoots, while the more sensitive ones cannot. The identification of salt tolerant chickpea landraces based on developing genetic variability is a suitable strategy to combat against salinity problems arising in arid and semi-arid areas.

Some Aspects of the Relationship Between the Quality of Sheep Milk and Dairy Products
12-15Views:84The correlation between the quality of raw milk and the quality of milk products is evident. In spite of this fact we can find only a few references contained exact data related sheep milk. In recent paper we investigated the effect of SCC of sheep milk on the cheese yield (semi hard traditional cheese) and certain texture parameters of yoghurt from sheep milk. We wanted to know the relevant limit values of these properties for dairy applications.
In our opinion – in the case of the cheese yield – that the strong negative effect can be experienced when SCC is above 700.000-1 million/cm3.
In the case of yoghurt from sheep milk the limit values of SCC can be 1 million/cm3 for Adhesivity and Whey draining and 500.000/cm3 for Hardness. Considering these limit values in the selection of milk become materialise the highest quality of products and the economical production. -
Effect of Rootstocks on Blooming Capacity and Productivity of AppleCultivars
14-20Views:98The experiment with three different rootstock cultivars was set up in a commercial apple orchard at Nagykutas, which is situated in the western part of Hungary. The aim of our two-year-study was to determine the effect three different growing rootstock cultivars (M9, MM106 and seedling) on the flowering and productivity of 33 apple cultivars. Our observations included the following measurements: the date of the beginning and the end of flowering, flower density, fruit density, fruit numbers per tree and tree productivity. According to our results, it was found that the different growing rootstocks have a great determining effect on the above measurements. Our results showed that the flowering period was similar for all cultivars on the three different rootstocks. However, the flowering and the fruit setting decreased in the order M9, MM106 and seedling rootstocks. In contrast, the fruit number per tree followed, in decreasing order, MM106, seedling and M9 rootstocks.

Effects of some herbicides on the microbiological characteristics of soil nitrogen cycle under maize plantation
93-100Views:71Nitrogen is a key element for the living organisms and influence not only for the quantity but for the quality of the yield, considerable. Availability of nitrogen from the soil is influenced by several microbiological processes of the Nitrogen-cycle. Among the intensive agricultural production the herbicide application cannot be omitted more information needs therefore about the inhibitor effect of herbicides on the different microorganisms.
An experiment was set up on calcareous chernozem soil under maize culture. Effect of four different herbicides (Acenit, Frontier, Merlin, and Wing) was investigated. The effect of herbicides was measured to four microbiological parameters of the Nitrogencycle (abundance of nitrifying bacteria, nitrate solubilisation, biomass nitrogen and urease enzyme activity). There were singledouble- and five times of recommended doses of herbicides applied for two onsecutive vegetation periods.
From the results of the different doses of herbicides, the following can be stated:
– The Acenit has a stimulating effect on nitrifying bacteria in general. The Frontier and Merlin also influenced the quantity of nitrifyers, however in certain cases decreased in another cases increased the number of bacteria.
– The double doses and five times doses of herbicides was found to be increasing the nitrate content of soil, -especially in 2006.
– The quantity of microbial biomass nitrogen increased in the 60% of treatments and decreased in the 40% of the treatments.
– Except of the result of Wing in 2006 and Merlin in 2005, the effect of simple dose herbicides was the smallest on the urease enzyme activity. According to the results the effect of Merlin was positive; the effect of Wing was negative on the soil enzyme’s activity.
Regarding the application of four different herbicides in three different doses on the microbiological parameters of soil (at two consecutive years-) in 39% of the treatments has resulted a significant inhibitory effect, 28% of the treatments, however have significant stimulating effect on the parameters measured. More than 50% of the inhibitory effect was measured in case of the Wing, at more than 50% of the Frontier the microbiological parameters have not changed. -
Interactive evaluation of the main agrotechnical factors in rape production
71-79Views:78Our polifactorial rape research was carried out at Látókép Research Centre of Debreceni Egyetem AMTC, 15 km away from Debrecen. The aim was to study the unique effect and the interactive effect of more factors. The research factors were the following: cultivation, time of sowing and nutrient supply. Soil moisture datas proved unambiguously that increasing amounts of chemical fertilizer raise the water consumption of rape, lack of water in fertilized plots were always bigger then the water deficit in control plots. The highest amount of water deficit was experienced in the case of arable plots. However, increasing amounts of chemical fertilizers raised the amount of yield proportionately. We experienced yield depression only in the case of arable plots at the highest level of chemical fertilization. In polifactorial rape research sowing of 24th August 2007 of 2007/2008 was the most optimal in point of the amount of yield. This is most-significant in the case of loosening tillage and disking tillage plots, while the plots of ploughing lag behind those two in point of average yield. We experienced the biggest differences of yield in the case of different tillage plots of sowing on 24t August 2007. Still not even the plot with the highest average reached the limit of 4 tons, which can be attributed to high rate of lodging and the harvest loss caused by this. The biggest amount of yield was experienced in the case of sowing of 24th August 2007, with the highest level of chemical fertilization at loosening tillage plot (3930 kg/ha). We can observe big differences between the tillage methods; plots of loosening show a much better average yield then plots of disking and ploughing tillage. Considering the first observed crop year we can state that alternative tillage methods do have a future in rape growing of Hungary.

Role of some agrotechnical elements in the precision crop technology of cereals
241-244Views:115The crop models and precision technology have an important role in the development of winter wheat and maize agrotechnics, which crops have determinative role in Hungarian crop production. The effects of agrotechnical elements (crop rotation, fertilization, irrigation, crop protection, plant density) were studied in our longterm experiments on chernozem soil. Our scientific results proved that the high yields, and good yield stability were obtained in the input-intensive crop models. Maize had lower ecological adaptive capacity than winter wheat. The optimatization of agrotechnical elements reduces the harmful climatic effects so we can increase the yield and yield stability of cereals agro-ecosystems. The yields of wheat varied between 2 and 7 t ha-1 in extensive and 8 and 10 t ha-1 in intensive crop models and the yields of maize ranged between 2 and 11 t ha-1 and 10 and 15 t ha-1, respectively.

Applicability of precision weed detection technologies
163-168Views:156In an agricultural field or horticultural plantation, weeds compete with cultivated plants for water and nutrients. The transpirated water by the weeds is needed to be replaced, which saddles surplus costs on the farmer, which could reduce the profitability of crop production. The aim of the precision plant protection system is to protect cultivated plants by applying site-specific technologies and optimized herbicides combination and methods, without environmental damage. The first step of precision weed control is the scouting for weeds. Traditional and modern (passive and active remote sensing) weed surveying technologies are available to detect weeds. The examination was carried out in an intensive apple orchard with drip irrigation system, protected by hail net of the Study and Regional Research Farm of the University of Debrecen near Pallag. The spectral-based weed detection was worked out by the Tetracam ADC broadband multispectral camera and the GreenSeeker 505 vegetation indexmeter. A strong correlation observed between vegetation indices and weed coverage. Based on the collected data, weed maps are created in appropriate software environment, thus the spatial distributions of the weeds are determined. The species level discrimination and the recognition of weed structural parameters were executed based on the 3D point cloud data by Leica ScanStation C10 laser scanner.

Recent data about the fish consumption of great Cormorant in the area of Hortobágy Fish Farm Co
75-80Views:195The cormorant (Phalacrocorax carbo) is a bird species that nests sporadically but in colonies, besides larger fishponds and rivers in Hungary. The number of its individuals has been increasing during the last two decades. The species eats solely fish, therefore it can cause serious depredation of the fish stocks in fishponds of intensive system and after the freezing of the ponds, in larger rivers, which are not yet frozen. The aim of our research was to reveal the damages the birds can cause on the studied areas and the extent of the losses the Hortobágy Fish Farm Co. has to realize.
Our studies were carried out between April 2012 and November 2014. During cleaning, the investigation of the craw contents of the birds and their biometric studies were conducted. The results revealed the diverse food base of the species. In the samples, we have determined 379 fish individuals; in 368 cases, the exact fish species were determined, too. Significant differences were found between the consumed fish species rations of the units (P=0.05% beside). We have also found significant difference in the fish consumptions of adult males and females.
Under the ever harder fish production conditions, the presence and thus the permanent predation of the birds affect the fishermen. In favour of maintaining ecological balance as well as to hold the income of the fish farmers, elaboration of adequate protective and preventive methods will be needed in near future.

The examination of the marigold’s (Calendula officinalis L.) nutrient requirement in small-plot trial
61-66Views:150During our research we investigated the marigold's (Calendula officinalis L.) nutrient requirements with different fertilization treatments in small-plot trial. We measured the harvested marigold's drug's raw and dry weight on a weekly basis from July 6th until August 17th. We were using SPME (Solid phase microextraction) and GC-MS (gas chromatograph-mass spectrometer) to examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage.
It was concluded, based on the results, the N30P40K60 fertilization setting is ideal in terms of the quantity of the marigold drug. Both the raw and the dry weights' measurements of the case, this fertilization setting have the most important effect on the herb's yield. The analysis of variance didn't show significant differences between the plots with different fertilization settings. We discovered relationship between the drying loss and the increasing quantities of nutrients. We think it may be possible the Alpha-thujon's and Alpha-cadinol's production and the drying loss's data are connected, which appear to confirm the N15P20K30 treatment's data.

The role of production site isolation in the plant health situation of sweet chestnut (Castanea sativa)
79-82Views:146The most destructive pathogen for the European chestnut is the blight fungus Cryphonectria parasitica (Murr.) Barr. The spread of the fungus was very fast in Europe within a few decades in the second half of the past century. During the tree-health checking in the chestnut and
walnut plantation in Romania, Hargita county, next to Homoródkarácsonyfalva village, we especially concentraded on the signs of blight disease occurrence. The grove is laying on a western slope, under a pine forest. This favourable geographical space protects it not only from pathogen attacts, but it has a special, mild microclimate for nut and chestnut trees. The European chestnut could be a valuable member of local forests, opening a new perspective under conditions of climate changes. -
Connections of the Economic, Ecological-Environmental and Social Functions of Rural Development in Communities Bordering the Hortobágy
203-211Views:61investigated the economic, ecological-environmental and social functions of rural development in communities bordering the Hortobágy National Park, such as in Balmazújváros, Hortobágy, Tiszacsege and Egyek. My purposes focused on four issues: (1) to work out a method on the basis of the examined and cited literatures, which defines the development of communities from economic, ecological and social aspects of rural development; (2) to reflect the changes in the role of agriculture; (3) to analyse the effects, advantages and disadvantages of Hortobágy National Park in relation to the economic, ecological and social lives of the examined communities; and (4) to make an economic analysis on the alternative income sources of Hortobágy, such as rural tourism, herb production and bio-farming in a family farm structure. When measuring the development of the communities I concluded that complex indexes hide the real consideration of the three functions of rural development and the possibility for comparing them on a community level. Furthermore, these 19 indicators are not enough to evaluate the situation, thus I raised the number of indicators and handled them on the basis of the three functions of rural areas. I classified the economic, ecological and social indicators into indicator groups within each functions, which make the determination of causes for underdevelopment possible. While only Tiszacsege and Egyek were considered to be backward on the basis of the complex index of the Hungarian Central Statistical Office, my investigations showed that even Balmazújváros and Hortobágy proved to be lagged behind from both economic and social aspects. The methodical development justified the hypothesis that few indicators are not enough to establish decisions objectively. New developmental orders emerged. Measuring development of communities may be all-rounded and more established by using this new method, which may result in objective preparation of decisions in rural development and more rational spreading of subsidies.

Differences in Regional Development in the Northern Great Plain Region
170-180Views:119An important ambition of EU regional politics is the reduction of disparities. An important strategical objective of the Commission is to terminate underdevelopment and to ensure the development of the regions based on the principles of solidarity, equity and justice. The commission has dedicated forty percent of its common budget to achieve these goals. The differences in development are significantly influenced by the economic characteristics of the specific region, the quality and quantity of human resources, the accessibility of the region and factors influencing local quality of life.
The new spatial structure has been formed by the processes of the change of regime, the events of nineties and the economic renewal based onforeign capital investments parallel with crisis phenomenon. The economic, political and social consequences of the transformation have significantly transformed spatial structure and increased disparities. New disparities have formed, which strengthened due to the formation of east-west slopes and local crisis zones. The outstanding improvement of the capital resulted in great regional development differences, which can be detected when examining regional distribution of gross domestic product. The Eastern part of the country was most heavily affected by the collapse of heavy industry and agricultural mass production based on the Eastern markets.
It is of key importance for the region to strengthen regional competitiveness, which requires the application of consistent development-politics. Economic development is the most important, which can also draw the possibility of establishing welfare infrastructures. It is important to develop the processing industry, the supply networks and to ease the lack of capital it is also important to involve foreign capital. Developing agriculture plays an important role in transforming the structure of the economy. Since the conditions of the region, its traditions and long-term competitive advantages are favorable, thus can represent a greater ratio in the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting marketing, quality agricultural development and producer-retail cooperation. It is also highly important to promote development in transportation and informatics infrastructure and human resources.
In the future – based on the strength of the region – it is necessary to achieve such a consistent regional development politics, which by validating the principles of regional politics, serves the interest of utilizing regional development supports most efficiently and prevents the irreversible underdevelopment of the region and promotes fast development. -
Hungary’s correspondence with the EU regulations regarding liquid bio fuels
119-128Views:71During the recent years researchers from different countries have found that our environment is at risk. It has been recognised by the leaders of the member countries and they have made decisions together concerning environmental protection in several agreements, contracts. Unfortunately, these decisions have been weakened and adumbrated on numerous occasions by certain interests.
However, the energetic exploitation of the biomass has been supported by the economic and social changes of the previous years, more specifically, that of the bio fuels. The significant increase in the price of the traditional energy sources, the import dependency of the countries, the foreseeable exhaustion of the resources, the changes occurred due to joining the EU are all such problems that facilitates the application of bio fuels, as a good solution.
Our country decided to modify the then existed bio fuel component rate of 2% to 5.75% which has to be achieved by 2010. Since then, in March 2007 it has been expanded to 10% until 2020 (concerning energy content). This decision was taken knowing that this year (2006) the bio fuel rate has been 0.5%. However, the rate of 2% has not been achieved even in the EU. One can understand that the implementation cannot be fulfilled without significant political decisions and support. The main reason for this is that the price of bio fuels is not competitive with the present fossil-origin energy prices in Hungary. So in 2007 several regulations were modified. The most important one is perhaps the regulation of the revenue tax, which caused the successful tax-differentiation concerning bio fuels in more member states between 2007 and 2008. Its essence is that the revenue tax is not decreased, but if the fuel does not contain a bio fuel component of 4.4 bulking percentage per litre, „punishment” tax has to be paid. Moreover, on behalf of the implementation, regulations concerning bio fuels and bio fuel components are improving
At present the production and the application of bio fuels without any support are not economical yet. That is why it is important to emphasize the support policy of our country. After joining the Union, the new members can receive some shares from the direct disbursements, but only a tan increasing rate, we can achieve the 100% in 2013, though there is an opportunity for national contribution. Energy plants produced in agriculture receive separate supplementary support which is an advantageous opportunity for the farmers of the sector. Bio fuels cannot only be supported through agriculture, of course, but by research development, investment etc.
All in all, it can be concluded that Hungary seeks to fulfil the EU responsibilities taken and by this, to contribute to the maintenance of the sustainable progress, decrease of environmental pollution and the import dependency of energy sources. -
Yield of herbicide tolerant sunflower hybrids due to the different herbicide treatments
121-125Views:118Sunflower is our most important oil-plant grown on the largest area in Hungary. In Europe sunflower has been grown since the 16th century. In recent years sunflower growing area is between 450-500 thousand hectares. Weed management in sunflower production is getting more and more difficult in case of annual and perennial dicotyledonous weeds, especially in dry springs. Two active ingredients, imazamox and tribenuron-methyl could be a solution for farmers for the control of these weeds in herbicide tolerant sunflower hybrids (Christensen-Reisinger 2000, Hódi-Torma 2004, Nagy et al. 2006). Most of the farmers choose the Clearfield technology and the use of tribenuron-methyl herbicides. In 2009 imazamox- (IMI) and tribenuron-methyl- (SU) tolerant sunflower hybrids were produced on 200 hectares in Hungary, of which 150 hectares was IMI, while 50 hectares was SU-hybrids. Small plot experiments were carried out to investigate the phytotoxicity of herbicides on imazamox (IMI) and tribenuron-methyl (SU) tolerant sunflower hybrids under field conditions. At harvest we measured the moisture content of achenes and average yield.
