Genetic diversity study of Hungarian honey bee (Apis mellifera L.) colonies – Previous announcement
61-64Views:182In Hungary, the Apismelliferacarnica is the native breed which is the only recognised and breedable honey bee in the country. It is assumed that there are a number of non-native and hybrid honey bee breeds in Hungary. The microsatellite and mitochondrial DNA surveys applied here will be utilised to easily and accurately identify the various sprads, and open up new ways in the research of honey bees. The isolation of the genomial DNS from 5 to 7 day old larvae samples was successfully carried out. In the future the plan is to carry out the measure with microsatellite markers. As an initial step the optimal annealing temperature was identified. In the mitochondrial DNA survey the COI-COII mytochonrial regional primer due to its low anneling temperature cannot be used with any normal sequencing methods. By using these method the aim of this research is the measurement of genetic variance.

Change of cultivation parameters of asparagus (Asparagus officinalis L.) on different nutrient systems
67-71Views:175The experiments were conducted at the Research Institute of Nyíregyháza, Research Institutes and Study Farm, Centre for Agricultural Sciences, University of Debrecen. We have studied the shoot number, plant height and fold thickness os asparagus for 3 years. We have set a fertilization experiment on 1500 m2 of plantations in 2013. We applied fertilizer, manure and sheet manure compost. The set yield we achieved by using fertilizer treatment. The Vitalim produced the largest crop, then the Cumulus and the lowest yield Grolim. We was produced by highest green mass was observed in Vitalim and Cumulus hybrids in each year. The Grolim hybrid produced the smallest shoot and plant height but the fold thickness was longer in the other two hybrids. Overall, the Vitalim hybrid has the best production parameters and each season.

Effect of cadmium and zinc contamination on the population dynamics of soil microorgani
73-77Views:125Changes in the population dynamics of microorganisms in a soil artificially contaminated with various doses of cadmium and zinc was examined from a quantitative point of view, under laboratory circumstances. The research was based on a chernozem soil originating from the area of a long-term microelement contamination model experiment (Nagyhörcsökpuszta, Hungary), which was carried out during 1991 in the Experimental Site of the Institute of Soil Science and Agricultural Chemistry, Centre for Agricultural Researche Hungarian Academy of Sciences, Budapest, Hungary. According to the amount of bacteria, microscopic fungi and nitrifying bacteria, it can be stated that the effect of contamination can be observed even in the perspective of nearly two decades. In more cases significant changes in the number of soil bacteria and microscopic fungi could be observed, and the nitrification activity increased in case of both microelements. Therefore the further research of changes in microbial activity of these soils can provide novel scientific results.

Evaluation of water balance in apple and pear trees
193-198Views:159A significant proportion of the aboveground green and dry weight of the plant constitutes the foliage. The canopy is an important factor
of plant growth. On one hand the canopy absorbs the solar energy, which is necessary for the photosynthesis, on the other hand accumulates
the absorbed nutrients by the roots, and the most of the water-loss happens through the foliages. The determination of the full canopy is not
an easy target. In our research we developed a measurement method to determine the leaf area. With the parameters of the examined tree
(leaf length and maximum width) and the data of ADC AM 100 leaf area scanner we determined the k-value, with which we can easily and
fast evaluate the leaf surface. Furthermore we defined from the water balance of compensation lysimeters the cumulative transpiration of
fruit trees and the efficiency of water use of trees. -
Study of animal welfare status in dairy cow herds in Hungary – looking for causes of lameness
47-50Views:206In the last 20–30 years lameness in cattle was found to be third the most influential disease next to mastitis and reproduction disorders. Studies have been established to explore reasons for lameness and prevention. The problem with more robust prevention plans is that knowledge and research evidence is not strong enough to run an effective prevention plan. The aim of the research is to look for reasons of lameness by observing number of cows on 6 farms during 2 lactations. Performance data will be put together to body condition score (BCS) and lameness scores. Other examination is focused on monitoring of 40 farms. This part of the project is more related to extension, collecting and sharing solutions for decreasing lameness. Producers are advised what kind of measures are possible to reduce occurrence of lameness. Effectiveness of those actions will be measured at the end of the study. The first preliminary results show lack in almost all preventive measures needed to be taken in minimising lameness. Those areas are related to poor facilities, lack of straw, problems with labour and basic management.

Hybrid-specific nutrient and water use of maize on chernozem soil
51-54Views:133The field research was set up on chernozem soil at the Látókép AGTC KIT research area of the University of Debrecen. The study focused on yield, water utilization, nutrient reaction and the amount of yield per kg fertilizer of corn hybrid NX 47279 in 2011 and 2012. Based on the yield results it can be concluded that the largest yield in 2011 was 15 963 kg ha-1 at level N120+PK, while in 2012, the maximum yield amounted to 14 972 kg ha-1 at level N90+PK. Surplus yield per kg fertilizer proved that in 2011 level N30+PK resulted in the highest surplus yield (42.3 kg kg-1) compared to the control treatment. In 2012, yield growth was 18.0 kg kg-1 compared to the control treatment. We measured at level N60+PK 17,5 kg kg-1 compared to at level N30+PK, at the N90+PK 17,7 kg kg-1 compared to at level N60+PK. level N30+PK kg kg-1, 17.5 kg kg-1 at level N60+PK and 17.7 kg kg-1 at level N90+PK compared to the control treatment.
Results of the regression analysis showed that the amount of nitrogen fertilizer was 117 kg ha-1 in 2011 and 111 kg ha-1 in 2012 in order to reach maximum yield. Doses of fertilizers above the amounts previously mentioned resulted in yield decrease. Our results indicated that in the drought year of 2012 the hybrid used available water more efficiently than in 2011. The hybrid produced 59 kg ha-1 yield in 2012 and 51.9 kg ha-1 in 2011 at an optimum nutrition level.

Contributions to the 2014 and 2015 flight pattern and damages of Carpomyia schineri Loew.
96-99Views:145The fly Carpomyia schineri Loew is a pest of the berries of the feral Rosa canina group but is can also be found in the berries of grown rose cultivars. The larva damages the flesh of the berry, several larvae can develop inside a single berry. It can decrease the quantity and ascorbic acid content of the tea and jam, which are important human ascorbic acid sources during winter. At the same time in trapping experiments the adult can be confounded with adults of the walnut husk fly (Rhagoletis completa Cresson). In collections of berries at several sites in Hungary damage levels ranged from 0.88% to 65.08 %. Based on these damage levels we had the impression that the yellow sticky traps CSALOMON® PALz or PALs baited with the synthetic Rhagoletis lure caught moderate numbers of adults and were not satisfactory for detection, consequently improving trapping methods is necessary in the future.

Effect of sowing technology on the yield and harvest grain moisture content of maize (Zea mays L.) hybrids with different genotypes
17-22Views:171From 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%.

The importance of millet production in regional production, with special emphasis on climate change
141-146Views:190Regional production is a traditional production structure developed adjusting to the geographical, climatic, biological and soil conditions in given production regions, a certain territorial specification of agricultural production, and a type of farming that best fits the natural conditions and takes the biological needs of plant and animal species into account as fully as possible. The most probable element of risk in plant production is the changeable, extreme weather. That is the reason why the specific characteristics of the place of production and the characteristics of regional production should be considered to a greater extent. The establishment of the range of varieties appropriate for the place of production is the key issue in regional production. One of our historically grown cereal plants that perfectly fits regional production is millet. Due to its short growing season, favourable reproduction ratio and the fact that it is relatively undemanding, it used to be grown in larger quantities in the middle ages. Its good nutritional values made it an important food item, but over time, as a result of industrialisation and technological progress; it has been eclipsed by other cereal crops. In our country it is mainly used to cook porridge, but it is also used in the form of flour and as a base material in the spirit drinks sector. In the recent decades, millet has been applied only in a small area, mostly as a secondary crop in areas that dried out from drainage water in late spring, or as a replacement of extinct sowings due to its late sowing time. Water will be the most significant factor for the future of agriculture, especially considering climate change.My examinations took place in the area of the Institutes for Agricultural Research and Educational Farm of University of Debrecen, in the Research Institute of Nyíregyháza, in a small-plot experiment with four replications in 2016. -
Supplementary botanical examinations for modelling the grass production of the great pasture of Hajdúbagos
17-21Views:75Our botanical survey at the great pasture of Hajdúbagos is a part of a broad research that aims to predict the production of the grass at the given area. As the mentioned pasture is a nature conservation area, the usage of artificial fertilizers or other classic grassland management methods in its handling are prohibited. Thus grazing is an important tool for the management of this area, however the not suitably regulated grazing order and the poorly calculated carrying capacity cause serious problems at some parts of the pasture. The prediction of the grass yield is essential to
avoid both over- and both under-grazing and for determining the optimal number of the grazing animal stock and the grazing method, thus the most suitable management strategy.
The potential grass yield is easily calculable with a computer model that will be established as a basis for determining the grass production. For the sake of getting an accurate view of the plant associations of the pasture, we created examination quadrates and determined all plant species found in the quadrates. After plant determination, we compiled a coenological table in which we marked besides the scientific name and families, the life forms of each species that refer to the structure, morphology and thus the adaptability of plants to their environment. We determined the
TWR, so the thermoclimate, water and soil reaction values, the nature conservation values, as well as the covering values of each plant species (DB), and the total coverage of the examination quadrates (B%).
According to the covering values, grasses proved to be characteristic plants at the examined pasture, thus we need to consider them influential in calculating the animal carrying capacity and with the rest of the information, we need to supply the model.
The life forms and TWR indicators, all together with the nature conservation values provide further important data to the development of the management suggestion of the protected pasture. By examining these values to different parts of the area, we could get an exact view on the measure of the degradation effects. This promotes the determination of grazing methods and the forming of the boundaries of certain pasture sections, to avoid those harmful anthropogenic effects that seriously endanger this extensive sandy pasture. -

The methodology of the Hooded Crow’s (Corvus cornix L.) colour ringing and the previous results
43-48Views:199The Hooded Crow (CorvuscornixL.) have moved in several Hungarian cities in the last few decades. It is breeding in Debrecen since 1959, and nowdays it’s presence can be detected at all points of the city, it is an permanent breeding species of the bird fauna. Our knowledge about the nature of urban races, including motion patterns, area fidelity is sufficiently incomplete. The aim of our research is to answer these questions by using our colour-ring program. In this study we present in details the methodology of Hooded Crow’s colour-ring program in urban area, and we also report our previous
achievements. -
Vegetable production based on waste heat in closed greenhouses considering economic usage and competitiveness of the European Union
41-44Views:131The study investigates two professional fields; the questions of vegetable production in greenhouses, the necessary steam supply and heat regulations. The actuality of this investigation is provided by the planning of a combined cycle power plant of 2400 MW in Hungary. According to the plans the steam developing by generating electricity in the power plant can be used to intensify the vegetable production. In my current study I present the experiences and results gathered as member of the research and development team led by Mr. Dr. Sinórós-Szabó.

The social basis of regional development in the North Great Plain Region
57-65Views:227It is a widely accepted practice in the European Union to break down countries into regions according to their stage of development, their cultural and economic characteristics. The basis of this methodology is the EU-conform MOTS system, which distinguishes territorial units on five levels. Besides the MOTS system, Hungary uses another system, too, which is the basis of our public administration, and whose roots go back to the times of King Saint Stephen: the county system. In Hungary, developmental decisions are taken by a county’s general assembly; at the same time, from an economic point of view the characteristics and competitive advantages of a county can be defined more precisely than those of a region.
Szabolcs-Szatmár-Bereg County and Hajdu-Bihaur County may be described with completely different characteristics, albeit both of them are part of the North Great Plain Region. On a county level economically important and justified developmental areas may be mapped more precisely.
Hajdu-Bihar County is the 4th most populous county in Hungary. With 80.2% of the population living in cities, the county is significantly urbanized. 2010 statistics show that the birth rate per 1,000 people in the county is practically the same as the birth rate of the country and that of the North Great Plain Region. Following the trends in developed countries, mothers now tend to give birth in an older age. Almost half (44.5%) of the children in Hajdu-Bihar County are born after their mother’s 30th birthday.
The general health condition of the population of Hajdu-Bihar County can be described with various indicators. In terms of medical and hospital care no difference can be observed between regional and national data, the county’s health care does not straggle behind. In sum, with the health care system of the county, estimated life expectancy of men is higher than the regional average, and in case of women it is higher than both the regional and national average, according to the given year’s mortality.
Children’s ratio among the county’s population is 15.9%, which is more than 1% over the national average. The ratio is higher in case of girls and boys alike. The income of the county’s population depends not only on labour income but also on social benefits. According to the analysis, the proportion of old-age pensioners and those receiving pension-like allowances within the whole population is somewhat lower in the county than the national average. The number of children receiving child-welfare and daytime care is prominent in the county.
The number of families and children receiving child-care allowance has not changed significantly in recent years. All important elements of social benefits have increased in the last decade. The quality of life of the county’s population is largely affected by the presence (or absence) of basic infrastructure in their environment. Research conducted at the settlements of the county shows that currently the greater part of the population has access to basic public utility services which form part of everyday services. Although they affect the general quality of life, the network of roads and passenger traffic have their real significance in terms of economic development. The county’s modern, paved road-system had already been built earlier.
Roads and pavements in inner-city areas have been paved up to 70%. The technical condition of roads and pavements can seriously impede the population’s mobility and it may hinder the development of certain settlements and districts.

Isolation and identification of endophytic fungi connected to Grapevine Diseases, from the Tokaj wine region, Hungary
61-66Views:227Grapevine Trunk Diseases (GTD) is one of the most important diseases in vineyards worldwide, which can be found in Hungarian vineyards as well. In Hungarian wine regions there is very little information about the occurrence of pathogens which cause GTD, in case of Tokaj wine region there is no knowledge about that, what kind of pathogens can be found in the vineyards.
The objective of our research is to assess the situation and occurrence of GTD in Tokaj wine region in cooperation with local specialists, as well as identification of pathogens which were isolated from the diseased trunks by morphological and genetic basis.
We were able to isolate endophytic fungi from all sampled grape trunk. The majority of them were determined as Diplodia seriata not only based on colony morphology, but also determined by rDNA sequences.

Evaluation of critical factors determining the profitability of sweet maize
97-102Views:139The main goal of this analysis was to determine, whether the production of sweet corn competitive is from the point of view of profitability and identify the main factors determining profitability. The hypothesis of this research was that sweet corn production is profitable and output factors (yields, selling prices) affect most significantly the profitability. The total costs of production with irrigation are 560 000 HUF ha-1. Average yield is 18 t ha-1, while selling prices on average of the last 5 years were about 38 000 HUF t-1. The realisable profit in the sector was 248 828 HUF ha-1. Direct cost-related profitability was 48.6% and profit level 26%. Elasticity analysis pointed out that the changes of selling prices and yields affect profitability. The critical value shows the turning point of profitability, which was at the yield of 13.82 t ha-1. It can be concluded, the hypothesis was true, because sweet corn production was profitable compared to other field crops.

A dual infection of two microscopic fungi on common milkweed (Asclepias syriaca) in Hajdúság region (East-Hungary)
189-195Views:197Common milkweed (Asclepias syriaca L.) is one of the most noxious and invasive weed species in Hungary. A. syriaca invades arable lands, horticultural and forestry plantations, natural and semi-natural habitats too. In cases of field crops it can cause considerable yield losses mostly in maize (2–10%), soybean (12–32%) and sorghum (4–29%), but only with high rate of coverage. It can also increase these problems that the common milkweed can be serve as reservoir and host for viruses, other pathogens and pests.
Because of the importance of common milkweed and in spite of demand to develop effective biological control, until now has not been developed a proper control program against A. syriaca. The aim of our research was to identify the necrotrophic fungal pathogens, which were involved in notable disease occurrence on this weed in different parts of Hajdúság region of Eastern-Hungary in 2016.
To the isolation of fungi from leaves and their identification were based on morphological colony characters on potato dextrose agar (PDA) and Sabouraud dextrose agar (SDA). To the description of conidia features were used PDA for Alternaria and synthetic low-nutrient agar (SNA) for Fusarium species, respectively. The examination of axenic cultures revealed that the fungi isolated from the leaves of common milkweed were Fusarium sporotrichioides and Alternaria alternata. -
Economics of site specific crop density in precision sunflower (Helianthus annuus L.) production
91-96Views:191In this research, the crop density of sunflower was examined, which, thanks to the tools available for precision crop production and knowledge of the market environment of sunflower production, best fits the heterogeneous areas of the given production zones and meets the economic requirements. These components together directly influence the effectiveness of sunflower production. In the year of 2021 and 2022, we carried out a site-specific crop density sunflower experiment in two fields with the same soil type, by sowing significantly different amounts of seeds within the given zones. We have established that the sunflower, although a plant with excellent adaptability, reacts sensitively to the place of production and the effect of the year, in zones with heterogeneous productivity, and shows a reaction to sowing with a variable number of seeds per zone, even when examined based on economic aspects.

Cross-Sectional Examination of Agricultural Firms in Relation to the Leaders’ Attitude
261-269Views:41As a PhD student at the Management Department of Debrecen University my project was to find examine circumstances of agricultural business entities in connection with structural, social and economic changes. This topic is integral part of the research program „Functional Study of Business-Management”, specified the topic „Structural Management Researches”.
My setting of objectives were to find any connection between changes and attitude of leaders. I tried to explore the direction, tightness and tendencies of these relations, to choose some special management-method, which ones are much more succesfull than the other ones during the change-managing process. The base of my experiences are the results of special questionnaires, which were sent to several member of different type of enterprises relating to agricultural activity. -
Result of Wine Consumption Survey
387-393Views:128Wine has always played an important role in the Hungarian culture and gastronomy. Today, average wine consumption is about 33 liter per person per year, which figure, comparing with datas in Western Europe, is acceptable. However, cultured wine consumption has begun to develop only in last few years. Consumers, whose knowledges about wines have been widening, demand quality wines. The number of high standard scientific contributions on this subject has risen greatly. But comparisons of them are rather difficult because of adopting different surveying methods. This research has supported and confirmed that wine is a confidental product and previous experience could be an important determining factor during wine-purchasing. Wine is popular as a present, so the nice, elegant look, proper bottles and labels are essential for the higher rate of selling. Further, price-value rate could also be a main factor during the customers’ decision. This survey is a result of a test-research and its methodolical experience will have been used in my following researches.

Rural Entertainment in the Püspökladány sub-region
110-117Views:92The Püspökladány statistical sub-region is geographically located in Hajdú-Bihar county’s south-west corner, in the area called Nagy-Sárrét. The tourism of the sub-region has been highly determined by the proximity of Hortobágy National Park and the presence of thermal water, one of the most important resources of the region. As Hajdú-Bihar county – especially Debrecen, Hajdúszoboszló and Hortobágy – possesses these attractive factors as well, in the Püspökladány sub-region rural tourism could be an important means of catching the interests of – mostly Hungarian – tourists.
In the course of this research, my objectives were to introduce the rural hosts of the sub-region, the main features and problems of rural hospitality as an enterprise and the characteristics and activities of rural tourist – from the view of the hosts.
I chose questionnaires as the method of the investigation, and evaluated them with the help of SPSS and Microsoft Excel software. During the evaluation, I calculated distribution, arithmetic mean, deviation and carried out significance-analysis.
The investigations confirmed my presumption, i.e. rural tourism has not gained ground yet in the Püspökladány sub-region. This statement is proved by the fact that I completed only 8 questionnaires in a sub-region with 13 settlements, where rural host activity concentrates on 3 settlements. The results of the questionnaire-evaluation prove the aforesaid. -
The character of the Bódva by the composition of the fishassociations
37-44Views:124The Bódva is one of our rivers that flow outside the Hungarian borders and arrive to the country across the frontier.The Bódva is approximately 110 kilometres long, its upper course is mountaneous- like in its springfield in Slovakia and it reaches the Sajó by flowing among the lower hilly region. The river wall is ravine-like in more places, the river itself is devious, and the water basin is rather variable as in the underlay muddy segments and heavily shingly beds can also be found.
By its fish fauna and physico-chemical characteristics, the Bódva is such aliving water that-after Borne and others (Nowicki, Thienemann) river zone system- can be regarded as an almost uniform typical Barbel zone.
According to our research program (2001-2005) and literature resources we estimated the fish fauna of the Bódva on both the Slovakian and Hungarian course. From some four decades to the wide ecofaunistic examinations of the near past we surveyed the quondam and present fish species of the Bódva River. According to our survey some 40 species compose the recent fish fauna of this river.
In the fish fauna of the Bódva those fish species that presently own a tight ecospectrum, sensitive to the changes of the environment thus so called indicator species, can also be found just like the less sensitive, invasive, aggressively reproducing species. By examining the changes in the fishfauna, the complex of those biogen and abiogen processes that affect the river can be indicated well. It can be stated that the fishfauna of the Bódva is rather rich with a countrywide measure also, and maintain a lot of rare, regressive protected and worth while protection species.
In the last period of the construction, the racial and quantitive composition of the fishfauna of the upper course of the Bódva has changed significantly. Certain species (in the Hungarian course) has vanished almost totally or at least their number declined not ably. Among the vanishing species there are not only a few substantial, protected species of the fauna (e.g. Barbus pelononnesius petényi, Leucaspius delineatus, Zingel sterber, Barbatula barbatula), but the number of the once mass species also decreased appreciably (e.g. Rhodeus sericeus, Alburnoides bipunctatus, Cobitis elongatoides). With the above mentioned changes the number of other animals also decreased in the course that we examined (e.g. mussels, crabs). We examine the cause of these changes in the pollution of the river and according to that in the decrease of the food source and the negative changes of the physico-chemical parameters of the water. -
Psychoactive substance the examination of implements and school factors among young persons living on country
11-17Views:94The study investigates the drug addiction, school problems and the underlying emotional disorders of provincial young people. I assumed that school problems are connected with the
youth’s legal and illegal drug consumption.
In my research, I used the Euroadad questionnaire taken at the Drug Ambulance of Nyíregyháza. The sample covered 144 interviewees, 76.9% of whom were „diverted” from jurisdiction. The other respondents volunteered for the therapy.
The linear regression analysis was applied to examine the interrelations between the elements under study.
All of the 144 respondents have tried or regularly apply some consciousness-modifying substance. Most of them are young adults. The preferred drugs were marijuana and ecstasy. All
consume alcohol as well. A significant connection can be proved between the majority of the psychological and school behavioural problems under survey and the drug abuse. The more problematic group covers those taking extasy. -
Investigation of the heat shock gene Hsp70 polymorphism in different sheep genotypes
41-45Views:190Nowadays the climate change has an increasing effect on the animals. The warming climate brings up several problems on the area of the animal husbandry, which ones are really important. From the first time the living beings have defensive mechanisms against the heat shock. In current examination we use– from Hungary and from other countries collected –samples of sheep breeds, which are living on different climate. Our fundamental assumption was, that the animals living on other climate adapted to the changes of the environment and there are differeces in their genetic background. These fixed mutations we are looking for in the HSP70 heat shock gene, but we haven’t found any polymorphism yet. We are going to involve further breeds and more individuals in the investigations.
