Drought cycle tracking in Hungary using Standardized Precipitation Index (SPI)
97-101Views:653Drought is one of the natural hazard risks which badly affects both agricultural and socio-economic sectors. Hungary, which is located in Eastern Europe has been suffering from different drought cycles; therefore, the aim of this study is to analyse the rainfall data obtained from ten metrological stations (Békéscsaba, Budapest, Debrecen, Győr, Kékestető, Miskolc, Pápa, Pécs, Szeged, Siófok, Szolnok) between 1985 and 2016, by using the Standardized Precipitation Index (SPI).
The results showed that 2011 was recorded as the worst drought cycle of the studied period, where the SPI ranged between -0.22 (extreme drought) in Siófok, and 0.15 (no drought) in Miskolc. In a similar vein, the study highlighted the year 2010 to be the best hydrological year, when the SPI reached 0.73 (mildly wet) on average. Interestingly, the Mann-Kendall trend test for the drought cycle showed no positive trends in the study area. Finally, more investigation should be conducted into the climate change spatial drought cycle in Europe.

The effect of water supply and crop year on the yield potential of sweet maize (Zea mays L. convar. saccharata Koern.) hybrids with different genotypes
203-210Views:460The successfulness of crop production is significantly affected by not only the the average yields that provide cost effectiveness, but also the success of striving for yield safety, therefore, varieties and hybrids tolerant to environmental stress factors are worth being included into the sowing structure. Our aim was to further the decision making of producers in prepaering the right sowing structure by the evaluation of sweet maize hybrids’ tolerance to excess rainfall.
We performed our examinations in an extremely wet year (2010) on chernozem soil on three sweet maize hybrids (GSS 8529, GSS 1477, Overland) in 12 replications. Comparing the yields of 2010 with those that can be expected under optimal rainfall conditions, we showed that the examined hybrids react to the amount of rainfall higher than their needs with yield depression. The excess rainfall tolerance of the examined hybrids is different in the case of each hybrid. -
Expansion of the small cable television counterparts of market leading commercial channels in view of Hungarian regional and social aspects
107-110Views:324Currently, there are 102 Hungarian-language television channels in Hungary. TV2 Hungary is the second largest commercial television channel. Current trends in the television market in Europe indicate that large channels are expanding their portfolios while at the same time selling their smaller units. This trend has now affected Hungary as well.
After having TV2 for 16 years, MTM-SBS Television Ltd. eventually expanded its portfolio with three new cable channels. The first new channel was FEM3, a channel directed at women, which was launched on January 1, 2010. A year later, the male channel, PRO4, was launched and finally, SuperTV2, primarily a premium entertainment channel, was launched on November 2, 2012. Although the main channel, TV2, remained free, the new pay channels on cable received a significant amount of investment from venture capitalists and Pro7Sat1 for the development of new content.
SuperTV2 is a premium channel. When the channel was launched, the goal was to target those viewers who had turned away from watching the increasingly less-sophisticated content on the commercial channels as well as those who were not drawn to the programming on public television. When the viewer stats were examined, the channel had proven itself. The premium brand of Super TV2 was successful in attracting new viewers and consumers and within a year it had gained a strong foothold over more than 100 other Hungarian-language channels.

Production of corn in Serbia in the light of climate change
305-322Views:377This paper presents the basic elements of maize production technology in Serbia. For their good knowledge, it is necessary to be familiar with the basic biological requirements of the species, phenology and its particular requirements for water, heat, soil conditions and mineral nutrition. A special emphasis in this paper is given to recent research by the author regarding the correction of production technology (selection of hybrids, time and density of sowing, etc.) from the aspect of knowing the weather conditions of the year to the moment of sowing and the amount and position of available nitrogen in the soil profile during the spring before sowing. In the light of predicted climate change conditions for the Republic of Serbia, the authors of this paper have proposed and appropriated adaptation measures. The general conclusion is that there are no general recipes for the correct production technology of this plant species, but should be adapted to each specific year, field and hybrid.

The situation and role of higher education in the North Hungary region
91-96Views:283Northern Hungary is one of the most disadvantageous regions of Hungary and the European Union; "keeping force" is extremely week. The regional spatial inequalities – despite the national and EU convergence program – have been increasing year by year. The social and economic situation of the region shows negative trends. Negative features of the migration processes are manifested in the candidates' choice for tertiary education has increased in the region in the past three years parallel with the proportion of those who are not on site, but primarily in the Central Hungarian region to continue their studies. An intensification of the negative trends is experienced in the economic processes both in jobs and the structure and performance of the local economy in respect of per capita income.
The transition from the nineties has decisively influenced the social and economic processes and the status of tertiary education institutions and their constantly changing role in the region. The role of education has become a key point of their activities as financing of the sector encouraged the institutions to increase the number of students and training offer, while R&D as form of cooperation in the economic sphere overshaded. Nowadays and over the past decade the increasing demand to transform their educational profile has increased in accordance with the social and economic situation of the region, adjusted to the catch-up and development opportunities of the region.

Effect of sowing technology on the yield and harvest grain moisture content of maize (Zea mays L.) hybrids with different genotypes
17-22Views:313From the aspect of the efficiency of maize production harvest grain moisture content shall be considered beside the amount of harvested grain yield. Hybrids with different genotypes and vegetation period length lose their moisture content different that is affected by row spacing and plant density – among agrotechnical production factors – depending on the given crop year. In the present research work three crop years with different weather conditions were studied (2013, 2014, and 2015). The small-plot field experiment was set up at the Látókép Field Research Centre of the University of Debrecen, Centre for Agricultural Sciences with four replications on a chernozem soil type. The effect of three factors was analysed in the experiment on yield amount and its moisture content. Factors were row spacing (45 and 76 cm), plant density (50, 70 and 90 thousand plants ha-1), while hybrids were of very early (Sarolta: FAO 290), early (DKC 4014: FAO 320, P 9175: FAO 330, P 9494: FAO 390) and medium (SY Afinity: FAO 470) ripening.
In the crop year of 2013 the highest yield was produced – regarding the average of the hybrids – by the application of a row spacing of 45 cm (4.5%, 673 kg ha-1), however there was no significant difference between the yield of the populations of different row spacings. Significant difference (14.9%, 1751 kg ha-1; 6.3%, 583 kg ha-1) could be found in case of yield between different row spacing applications in 2014 and 2015. The effect of insufficiently distributed low amount of precipitation and lasting heat days in 2015 could be revealed in yield amounts and harvest grain yield moisture content results that were lower than in the previous years. In 2015 grain yield moisture content varied between 10.3 and 13.9% in case of a row spacing of 45 cm, while by 76 cm between 11.0 and 13.9%.

Environmental friendly maize (Zea mays L.) production on chernozem soil in Hungary
133-135Views:541We have been studied the effects of crop-rotation, fertilization and irrigation on the yields of maize in different cropyears characterized
by different water supply (2007 year=dry; 2008 year=optimum) on chernozem soil. Our scientific results proved that in water stress
cropyear (2007) the maximum yields of maize were 4316 kg ha-1 (monoculture), 7706 kg ha-1 (biculture), 7998 kg ha-1 (triculture) in non
irrigated circumstances and 8586 kg ha-1, 10 970 kg ha-1, 10 679 kg ha-1 in irrigated treatment, respectively. In dry cropyear (2007) the
yield-surpluses of irrigation were 4270 kg ha-1 (mono), 3264 kg ha-1 (bi), 2681 kg ha-1 (tri), respectively. In optimum water supply cropyear
(2008) the maximum yields of maize were 13 729-13 787 (mono), 14 137-14 152 kg ha-1 (bi), 13 987-14 180 kg ha-1 (tri) so there was no
crop-rotation effect. In water stress cropyear (2007) fertilization caused yield depression in non irrigated treatment (control=2685 kg ha-1;
N240+PK=2487 kg ha-1). Our scientific results proved that the effects of abiotic stress could be strongly reduced by using the optimum crop
models in maize production. We obtained 8,6-11,0 t ha-1 maximum yields of maize in water stress cropyear and 13,7-14,2 t ha-1 in optimum
cropyear on chernozem soil with using appropriate agrotechnical elements. -
Productivity and Nutrient Reaction of Maize Hybrids
78-83Views:404Several factors influence the quantity and stability of maize yield, the most important being the nutrient supply, the hybrid and precipitation. In 2004, during the maize growing season the precipitation was more than the 30 year’s average, with 68.3 mm, but the distribution was unfavorable. The experiment was carried out in Debrecen at the Experimental Station of the University of Debrecen Centre of Agricultural Sciences, Department of Crop Production and Applied Ecology. We tested 10 various hybrids with their own genetic characteristics for five different fertilizer doses, in addition to the parcels without fertilization.
The favorable results reached were due to the rainy season. The average yield varied between 7.78-9.67 tha-1. The DK 440, PR37M34, PR38A24, PR39D81 and PR36R10 of the hybrids reacted to higher fertilizer doses with significant growth yields, the yield (more than 11 tha-1) was the highest for N200, P125, K150 fertilizing. The other hybrids, DKC 5211, Mv Vilma and MV Maraton, gave similar results at the N120+PK fertilizer dose and the ensuing doses depressed the yield. Fertilization was more effective thanks to the precipitation. The fourth and fifth dose increased or decreased maize yield depending on the nutrient reaction of the hybrid. The agro-ecological optimum of NPK fertilization was N120, P75, K90 kgha-1.
During the experiment we tested the moisture loss of five hybrids. The rainy crop year’s effect on the seed moisture content at harvest was higher than in previous years. The seed moisture content hybrids at harvest which have shorter crop years (FAO 300) was 18-19%, and hybrids with longer vegetation periods had more than 20% seed moisture content. DK 440 hybrid had the intensive moisture loss of the five hybrids, at the start of the measurement, the seed moisture content was higher than 40%, and it decreased to 18.6% by harvesting. -
Effect of harvesting time on the vitamin C content and yield of chili pepper
101-104Views:422For thousands of years, chili pepper has been used in cooking intensifying the aroma, colouring, and even flavouring with its pungency. Today ,it is also of interest for the various food and pharmaceutical industries due to its intrinsic characteristics. These characteristics of pepper and its yield can be affected by both the variety and the temperature fluctuation throughout the harvest period. The current work's objective was to investigate the effect of harvest time on vitamin C of different varieties of chili pepper C. frutescens and C. annuum cultivated in Hungary, as well as the yield of pepper in different harvesting periods. Vitamin C was determined by HPLC protocols. The differences between harvest times and varieties were analysed using Tukey post hoc test at 5%. All varieties showed fluctuation of vitamin C level, depending on the given harvest date. At the last harvest, all varieties had higher vitamin C content. All varieties had the same yield trend throughout the year but with different yields between each. Variety Hetényi Parázs had the highest vitamin C content and yield: 3720.53 µg g-1 vitamin C and 18.63 t ha-1 average yield, respectively.

Possibilities of Corn Seed Commercialization on the Hungarian Market in 2003
166-169Views:234According to the sales results of the past two years we can draw the conclusion that although the Hungarian hybrids have very good capabilities, they are still in a big disadvantage in the corn seed sales sector, considering other foreign varieties. These above mentioned disadvantages, as published in prior essays, are not because of the variety’s low quality, but the lack or little presence of marketing. In order to gain position and market on the seed sales sector in Hungary, a lot more has to be done in the area of advertisement.
Seed advertising is very particular and different from all other types of goods. To make growers familiar with your product, you have to be in continuous contact with them, through field days, exhibitions and presentations, besides the well known and in other areas also used quotidian advertisement methods.
Although Hungarian breeders reach better and better results each year, they still cannot catch up with the multinational companies spending millions of dollars on development and advertising, thanks to their financial position.
Finally we can state that choosing the appropriate variety for our needs and possibilities of land and machinery is of great importance in order to reach the best results we can. -
Interactive evaluation of the main agrotechnical factors in rape production
71-79Views:279Our 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.

Effect of two different cropyear and the agrotechnological factors on the agronomic characteristic of the winter weat in a lon-term experiment
143-149Views:469We studied the effects of crop rotation, fertilization and crop protection technologies on occurence of the major ear- and leaf-diseases (powdery mildew, helminthosporiosis, leaf rust, Fusarium wilt) and the degree of lodging in the winter wheat variety Mv Pálma in two very different years (2006/2007=dry; 2009/2010=rainy). The experiments were carried out at the Látókép Experimental Farm of the University of Debrecen CAAES in triculture (pea-wheat-maize) and biculture (wheat-maize) at five fertilization levels by applying three different crop protection technologies (extensive, average, intensive).
In the cropyear of 2006/2007, the disease severity of leaf diseases was higher than the average in both crop rotations in spite of the fact that the weather during the whole vegetation period was dry. Infection by powdery mildew, helminthosporiosis and leaf rust increased with increasing fertilization, the highest infection was measured at the highest fertilization level (N200+PK) in the extensive crop protection technology. According to the results, no infection of ears by Fusarium and no lodging occurred in either bi- or triculture due to the dry year. The extremely rainy weather in 2009/2010 was favourable not only for the vegetative development of the stand, but also increased the occurance of leaf-, stalk- and ear-diseases and a high degree of lodging was observed. The highest infection by powdery mildew was observed in the plots with the highest fertilizer dosage under an extensive crop protection technology. A much higher helminthosporiosis infection was measured than in the cropyear of 2006/2007. The wet weather and higher than average temperature promoted the occurence and spreading of leaf rust. Under an extensive crop protection technology, a leaf rust infection of 24% and 31% was detected after maize and pea as a forecrop, respectively, in the N200+PK treatment. As opposed to 2006/2007, the disease severity of Fusarium was 3–8% and 2–7% in the control after maize and pea as a forecrop, respectively. This value, similarly to that of other pathogens, increased with increasing fertilization levels. Due to the large vegetative mass, a significant lodging was observed in the wheat stands in both bi- and triculture (17–100%, 12–100%). -
Evaluation of harvesting technology of vineyard pruning based on a Mátra wine region case study
91-100Views:258Wineyard pruning utilization for energy purpose is not only a theoretical possibility, the machine background has also been developed. Economic- and environmental experimentations has made by specialists and they seek to developed the best practice in logistics suitable for local conditions and they propagate the results for the potential users. Nevertheless, the utilization does not seem to be typical in Hungary and some other wine-grower countries. For example, in Hungary the additional energy from vineyard pruning eventuates – tillage, nutrient supply; – phy+tosanitary, environmental pollution; – energy management and economic questions.
In Hungary the most important problem is practice of the vineyard pruning utilization were mentioned by the users is the establishment of collection system and the high logistic costs as Marczinkó (2007) experiences confirm this. As I experienced in practice, the winegrowers are uninterested in utilization. Most of them burn it at the end of the vineyard in many cases without considering of the relevant statutory prohibition.
As my own several years expriment shows at Mátra wine region it is not the technical background which causes the failure. We can use effectively balers or chippers for collection. The cost of chipping is 14 535–27 000 Ft per hectars with the introduced technologies on Mátra wine region. The cost of 1 GJ of heat production is 606–1125 Ft. We can substitute the fuel with vineyard pruning and it means approximately 115 000 Ft saving for a family household per year.

Competence modules of the agro-environmental engineering bachelor course in Hungary
229-236Views:326One of the most important goals of the Bologna Process is to introduce the three circle system: bachelor, master, doctorate courses. In Hungary from 2006/2007 academic year 132 bachelor courses are launched. One of the launched bachelor course is environmental engineering of which the scientific background and economical sector are rapidly changing. Hence, to help graduates from this area to find a job, it is very important to examine working activities, expectations of employers, to study requirements of the training programs, the system of competencies. Having examined these points, frameworks of professional requirements have been worked out by 27 validation tests. In this publication, the results of the research work related to the environmental engineering bachelor program were presented.

Changes in the Quality of Winter Wheat Varieties in a Comparative Experiment
179-183Views:628The hungarian seed grain supply offers more and more varieties from the field crops for public cultivation in every year. The number of the admitted varieties by state doubled from 1996 to 2001. The question is what changes can the varieties newly inproved show in the quality parameters.
32 varieties admitted in different years was examined on quality parameters as wet gluten content, valorigraphic value and falling number from period 1996-2001. We established that the newer varieties surpassed the traditional varieties of the variety-comparativing experiment in accordion to they wet gluten content. In connection with formation of valorigraphical value we saw that the new varieties got place in the varieties admitted for public cultivation in quality based examining. The varieties showed different reaction of fertilizer on the formation of these two parameters. In connection with the formation of the value of falling number the examined varieties suited for the requirements of quality crop production in the experimental years excepted some of them. -
Effect of Storage on Fruitquality of Apricot (Prunus Armeniaca)
164-169Views:364The quality of a product is determined by numerous characteristics. As quality characteristics are polygenic, they cannot be improved easily. Moreover, there often is a negative correlation between the different parameters in the case of apricot. The firmness of fruits decreases with increasing size. The year effect also has a great influence on the expression of the potential quality of the given cultivar.
Our examinations were carried out in 2004 at Boldogkőváralja, in the cold storage plant of the Northcot Ltd. We monitored the development of fruits from fructification until harvest, and also the quality changes during storage. 100 fruits were observed from each cultivar directly after harvest. We measured height, width, weight, firmness, dry matter content and seed weight. From each cultivar, 100 fruits were stored, of which 25 fruits were observed each week. The value and the dynamics of the changes in the parameters compared to the values at harvest varied greatly for the different cultivars. Strong correlations between the parameters have not been found within one cultivar either. The heavier fruits did not lose more weight, either in absolute value or relatively, than the lighter fruits. The increase in the firmness of fruits was not accompanied with a desirable decrease in the dry matter content. -
Comparative examination of a mineral fertiliser and a bacterial fertilizer on humic sandy soil
111-116Views:356In our pot experiment, the impact of a bacterial fertilizer, Bactofil® A10 and a mineral fertilizer Ca(NO3)2 applied in different rates was studied on some soil chemical and microbiological characteristics of a humic sandy soil (Pallag). Perennial rye-grass (Lolium perenne L.) was used as a test-plant. Samples were collected four and eight weeks after sowing in each year. The experiment was set up in 2007-2009 in the greenhouse of
the UD CASE Department of Agrochemistry and Soil Science. The available (AL-extractable) nutrient contents of soil, among the microbial parameters the total number of bacteria, the number of microscopic fungi, cellulose-decomposing and nitrifying bacteria, the sacharase and urease enzyme activity, as well as the soil respiration rate were measured.
Statistical analyses were made by means of the measurements deviation, LSD values at the P=0.05 level and correlation coefficients were calculated. Results of our experiment were summarised as follows:
− The readily available nutrient content of humic sandy soil increased as affected by the treatments, in case of the available (AL-extractable) phosphorus and potassium content the higher value was measured in high-dosage artificial fertilizer treatment.
− The treatments had also positive effect on several soil microbial parameters studied. The higher-dosage mineral fertilizer treatments had a beneficial effect on the total number of bacteria, cellulose-decomposing and nitrifying bacteria. No significant differences were obtained between the effect of treatment in case of the total-number of bacteria, the number of microscopic fungi and nitrifying bacteria.
− On the sacharase enzyme activity the artificial fertiliser treatments proved to be unambiguously stimulating, the urease activity significantly increased on the effect of the lower-dosage Ca(NO3)2 artificial fertilizer treatment.
− The soil respiration increased in all treatments in related to the amounts applied, significantly increased in the highest rate of Ca(NO3)2 fertilizer addition.
− Some medium and tight positive correlations were observed between the soil chemical and microbiological parameters studied in case of both nutrient sources.
Summarizing our results, it was established that the organic and all the mineral fertilizer treatments had beneficial effects on the major soil characteristics from the aspect of nutrient supply. In majority of the examined soil parameters (AL-extractable phosphorus- and potassium, total number of bacteria, number of cellulose-decomposing and nitrifying bacteria, activity of sacharase enzyme) the high rate of Ca(NO3)2 mineral fertilizer treatment proved to be more stimulating, but at the same time the high rate bacterium fertilizer resulted in significant increases in
the nitrate-N content, the AL-potassium content of soil, the total number of bacteria, the number of cellulose-decomposing and nitrifying bacteria and the urease enyme activity.
Our examinations showed that the mineral fertilizer treatments proved to be more stimulating on most of the soil parameters studied but according to our results, it was established that Bactofil is efficiently applicable in the maintenance of soil fertility and the combined application of
mineral fertilizer and bacterium fertilizer may be a favourable opportunity – also in aspect of the environmental protection – in maintaining soil fertility. -
Study of some physiologic properties of different genotype sweet corn hybrids
105-110Views:283The effect of nutrient-supply (control, N120+PK) and two different genotypes on the physiologic properties of sweet corn has been investigated in the crop-year of 2011 on chernozem soil in the Hajdúság region. The experiments were carried out at the Experimental Station of the University of Debrecen in Debrecen-Látókép. The experiment was sewn in two different sowing times: the 21st April can be considered as an early, while the 19th May as a late sowing time. The two involved hybrids were Jumbo and Enterprise. The applied plant density was 65 000 plants per hectare.
Our aim with this experiment was to study the plant production, just as the main affecting factors of its development and dynamics, like nutrient-supply and genotypes. We aimed to study and analyse the relationships between these factors and plant production. In this study following parameters were measured and calculated: photosynthetic activity, chlorophyll-content (SPAD-value), leaf area index (LAI) and leaf area duration (LAD). Regarding the analysis of photosynthetic activity values no obvious relationship between the measured values and the applied hybrids, just as nutrient-supply has been revealed.
Analysing the SPAD-values it can be stated that the chlorophyll-content of the measured leaves showed an increasing tendency due to the nutrient-supply. The highest values have been measured in the intensive cob development phase of the early sowing time plots.
Regarding the LAI-values we have found significant differences between the fertilizer treatments in both sowing time treatments. In case of the leaf area duration values – that is derived from the LAI values – nutrient-supply has positively affected the duration of the assimilation area. -
Biological control of sweet chestnut on Pécsbánya, Hungary
77-81Views:564The supervision of plant hygiene of sweet chestnut grove on Pécsbánya (South Hungary) started more than four years ago. Hypovirulent strains were applied as a biological process to control Cryphonectria parasitica fungus which causes the chestnut blight disease. By now the performed interventions have shown obvious results, the vitality of the trees has greatly improved, the amount of harvested nuts is increasing, and the hypovirulent strain has been spreading within the area. During plant health inspection the galls of chestnut gall wasp (Dryocosmus kuriphilus) was found in the year of 2015, which is the obvious symptom of new occurrence of the pest. The pest was eradicated by destroy galls, which allows taking out of consideration the damage by now in this area.

How have thermal conditions changed in different phenological stages of apple (Malus domestica) in Northeastern Hungary?
137-142Views:250In temperate climates, most fruit trees need cold weather, low temperatures in winter, and a certain amount of heat during the growing season until harvest. One of the most apparent effects of climate change is the elevated temperature in all seasons of the year. In our study, the changes in thermal conditions have been calculated in Hungary's most significant growing region of apples using the Chill Unit for winters and the Growing Degree Days for summers. The meteorological data were obtained from the gridded dataset of the Hungarian Meteorological Service on a 10 km × 10 km grid, so the whole studied area is well-covered over the last 50 years. The results show that the trees are more exposed to early budding than a few decades ago. Furthermore, the accumulated heat amount in summers has increased drastically, which may increase the heat stress and lead to higher yield losses.

The Present and Future of Tokay Aszú
87-92Views:257Tokay 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. -
Feeding questions of organic lamb fattening
155-160Views:236Organic farming has done in line with conventional farming in the Karcag Research Institute of DU CASE since 2001. Our organic farming activities were enhanced with sheep farming and
grassland management in 2005. We started our study of technology development of organic lamb fattening and the treatment of its economic effect this year. Our goal was to develop
the elements of the technology to reach a more efficient organic lamb fattening. We also studied what economic advantages the organic sheep farming could realize in the present economic environment. Our studies were carried out between 2005 and 2007. We established that the excellent ewe feeding (good quality of fodder and silage) can decrease the lamb feeding cost between the 2nd and 8th weeks of the lambs’ life. We established that the
yield of convention lambs are significantly higher than the yield of organic lambs. The cost of organic lamb fodder is significantly lower than the cost a convention lamb fodder, but the profit was higher in the case of convention lamb fattening. The organic lamb fattening technology (without extra price) is not competitive to the conventional lamb fattening technology. We think that the profitability of organic lamb fattening is significantly less than of the convention one. The organic lamb price should be 20-30% higher than the other price to be competitive. Unfortunatly there is only a little demand for organic lamb and there is no difference between the prices of organic and convention lambs, so organic sheep farmers have worse economic circumstances than conventional sheep farmers. -
Arthropods assiciated with the stinging nettle in Hungary
97-103Views:335Stinging nettle (Urtica dioica Linnaeus) (Urticaceae) is a well known medicinal plant cultivated in some European countries for a long time. Because of its multiple usability (food, medicinal plant, feed, fiber), adventageous agrotechnical qualities and low demands for plant protection, its more extensiv utilization can be expected. However, during cultivation from time to time little damages can be occurred on it. The aim of this paper is to show and estimate the most important arthropods (pests and natural enemies) of stinging nettle. Under the pests characterized in the paper according to the references the peacock and the small tortoiseshell are the most important species living on stinging nettle. Their individuals from time to time propagated can cause an important damage on nettle leaves in cultivated nettle stands or assemblages. On the base of a 12 year observation period (Gödöllő, Debrecen, 1998-2010) the following species have been observed: Psylliodes attenuata, Chrysomela fastuosa, Phyllobius pomaceus, Pleuroptya ruralis, Inachis io, Aglais urticae, Microlophium evansi, Microlophium carnosum, Aphis urticata, Dasineura urticata, Tritomegas sexmaculatus. Inachis io has been the only species which during the observation period did danger the stinging nettle stand. The other pest species have not threated even timely either the stinging nettle stand or a single plant. The number and diversity of natural enemies was rather low: running crab spiders (Philodromidae), tangle-web spiders (Theridiidae), crabbing spiders (Thomisidae), lacewings (Chrysopa perla, Chrysopa formosa), coccinellids (Coccinella septempunctata, Propylea quattuordecimpunctata, Adonia variegata), hoverflies (Episyrphus balteatus), earwigs (Forficula auricularia), scorpionflies (common scorpionfly (Panorpa communis) and European paper wasp (Polistes dominula) predominated.
