Stevia (Stevia rebaudiana B.) yield in the case of different production technologies
71-77Views:418Stevia rebaudiana B. offers a natural alternative of sweetening, potential health promotion plant, and our country shows increased interest about cultivation in Hungary in addition to the neighboring European countries. The agricultural production system installation necessary
understanding of the needs of the plant, as well as exploring the agronomic potential. Field experiments were conducted in 2015 with the aim to highlight some of the technological production parameters and correlations between them. We have reviewed the most important agronomic factors, the spacing (50×50 cm and 33×33 cm), ground covering (agro-cloth covered and uncovered/ control), their vegetative growth (first-,second-order branch), herb yield and quality in effect.
Based on empirical evidence, that the Hungarian climates also have the opportunity of 3 cuttings during a growing season, besides of early planting, optimal climatic conditions (in October didn’t reduce the daily minimum temperature below 0 °C, after cuttings the maximum interval values remain below 40 °C), and adequate water supply and crop protection facility. The 33×33 cm spacing evaporates more than 50×50 cm spacing, because of the dense population, the continuous canopy less able to breathe, so there are serious chances to the pathogen colonization.
Based on the results of our research to the wider 50×50 cm spacing favorable appreciate the stevia optimal progress in terms of qualitative and quantitative parameters of the yield. The stevia yields produced in the Northern Great Plains field cultivation can produce similar results as stevia crop yields in warmer climates, where the primary crops. Our research experience suggest that there is a viable domestic stevia cultivation, developing the necessary technology is still growing further investigation justifies. -
Awareness and adoption of a nurse sow management system among small-scale pig farmers in Nakuru County, Kenya
113-120Views:411This study aimed to assess the level of awareness and adoption of nurse sow management strategies among small-scale pig farmers in Nakuru County, Kenya. The research included a survey of pig farmers who visited the Nakuru Agricultural Show in July 2023. A total of 139 farmers were interviewed within 5 days of the show. The corresponding author interviewed the respondents in a face-to-face engagement, where questions on nurse sow management were initially drafted in English and translated into Kiswahili, i.e. the second language in Kenya. The obtained results indicated that farmers came from two main regions of the county: the northern part (54.7%, 76/139) and the southern part (45.3%, 63/139). Levels of awareness and adoption were insignificant between the two groups (χ2, p<0.05). A major obstacle to the adoption of this strategy was identified as feed challenge at 77.7%; (108/139) and market issue at 59.7%; (83/139). This study identified important aspects and limitations that should be considered when developing sustainable productivity development strategies for Kenyan pig farmers. To assist the sustainable growth of small-scale pig production, the authors suggest government measures that shield farmers against exploitation of feed and marketing components, as well as advocating for effective breeding to increase live born.

Potential use of bamboo in the phytoremediation in of heavy metals: A review
91-97Views:911There are many literature sources focusing on the phytoremediation of woody plants, but there are only few dealing with the phytoremediation of bamboo plants. Phytoremediation technology has the advantages of little disturbance to the environment and low remediation cost. Bamboo mainly exists in tropical and subtropical regions. As an energy plant, bamboo has a fast growth cycle, large biomass, simple cultivation, high economic efficiency, and convenient harvesting, which highlights the advantages of bamboo in phytoremediation. In addition, bamboo plants have good tolerance and uptake ability to heavy metals and have high application potential and development value in uptaking heavy metal contaminated soil. However, due to climate, temperature and other reasons, bamboo cannot be widely planted in most countries. Research status of remediation of heavy metal contaminated soil by bamboo plants is summarized. The feasibility of its application in heavy metal contaminated soil is discussed in this paper. Aiming at the shortcomings of existing research, bamboo plants have a prospect in the field of plant phytoremediation for the future.

The presence of the undertaken social and economic role in the university's strategy-making
93-96Views:257It is vital to examine the strategic plans and leadership insights of the university, the faculties, the departments and the institutions in the research of the „third mission” of the universities. Because of the undertaken social-economic role in the region it is indispensable to know the turbulently changing environment (hazards – opportunities), to map the competencies available in the university (strengths – weaknesses) and to recognize the relations between the external and internal environment. It is an important factor to define the strategic directions of the departments, examining them in direction dimension (pro-active – adaptive) and in role dimension (top-down – bottom-up). The main objective of this research is to recognize the formal and informal strategic visions of the institutes and departments in the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen, and to examine how these visions are related to the university's role in the regional innovation system.

Micropropagation of Leuce-poplar clones and its role in selection breeding
43-48Views:370Leuce-poplars (mostly white poplar and its natural hybrid grey poplar) are native tree species trough Hungary. They are covering more than 4.0 per cent of the Hungarian forested area (77 000 ha). The white (grey) poplars play a significant role in the forestation under sandy soil site conditions as well as they are of importance from nature conservation point of view as well.Long-term selection breeding work is going on at the National Agricultural Research and Innovation Centre Forest Research Institute (NARIC FRI), involving selection of fast-growing Leuce-poplar clones under dry site conditions.Micropropagation technology is relatively quickly spreading in forestry. In vitro multiplication of trees is applied mainly in fruit growing in Hungary, in case of forestry it is used mainly for selection breeding.This paper presents a short overview on the micropropagation trials with different Leuce-poplar clones and the early evaluation of the seedlings growing of the micropropagated clones/varieties. -
Growth and yield patterns of black locust (Robinia pseudoacacia L.) sample trees affected by site conditions: case studies
125-128Views:333The trees removed from the long-term experiment plots are available for the measurements as lying trees. Through the determination of the volume in sections along the stem, the stem form, the stem volume and other factors can be specified. The comparison of the stems of individual trees of first and third yield classes of black locust (Robinia pseudoacacia L.) stands shows that site conditions have a main effect on the yield (mean tree volume). The difference can be as high as 53% at the age of 30 depending on the sites. To determine the growth patterns based on tree volume is rather a new approach in the light of the relevant literature. The obtained results also highlight the importance of choosing the appropriate tree species for a given site.

Evaluation of water balance in apple and pear trees
193-198Views:609A 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. -
Connections between the roma segregation processes and home circumstances in the outskirts of Hajdúböszörmény
57-61Views:199In order to analyze the social status of local gipsies – both inside the community and among themselves – we conducted an empirical research of 300 participants, in which we took the distinctive spatioand sociostructural features of Hajdúböszörmény into consideration. Furthermore, a second research was also carried out in which we questioned 25 prominent persons. Participants were selected in a way that the study may give a realistic picture of each of the segregated areas of the town (focusing on social, educational and realty issues), thus besides questioning professionals dealing with the concern of gipsies on a daily basis, we decided to involve representatives of the local government as well. The reports concerning the realty status of the segregated areas were supplemented with further material provided by the local government.

Nutrient and water utilisation analyses of maize on chernozem soil in a long-term field experiment
77-82Views:499We have conducted our research at the Látókép Research Farm of the University of Debrecen RISF Centre for Agricultural and Applied Economic Sciences during the cropyears of 2007, 2008 and 2009, on chernozem soil. In the case of crop rotation three models were set (mono-,bi- [wheat, maize] and triculture [pea, wheat, maize]). The five nutrient levels applied during the treatments were as follows: control [untreated], N60P45K45, N120P90K90, N180P135K135, N240P180K180. The conclusion of our results was the following: the crop rotation, the nutrient supply and the amount of precipitation all influenced the quantity of maize yield. As an effect of the increasing nutrient doses yield increase was experienced compared with the control treatments. In the average of the years the highest increase in yield excess/1 kg of NPK fertilizer was measured in the case of the monoculture (13 kg ha-1). As a consequence of is soil extorting effect the monoculture responded more intensively to the nutrient supplementation than the biculture or the triculture in the studied cropyears. In addition, we have observed that the three-year average yield amount per 1 mm precipitation was significantly influenced by the nutrient reserve of the soil. In the monoculture during the control treatment this value was 25 kg mm-1, the value measured in the case of the biculture turned out to be more favourable (42 kg mm-1).

Effect of genotypes and cropyear on thedifferent cultivation parameters of asparagus (Asparagus officinalis L.)
31-34Views:318The experiments were performed in the Research Institute of Nyíregyháza Research Institutes and Study Farm, Centre for Agricultural Sciences University of Debrecen of 1500 m2 asparagus plantation. The asparagus was planted in 2011. We were determine the number of shoots, plant height and fold thicknes of asparagus hybrid. We can continuously monitored the growing parameters of asparagus. The harvest of asparagus was started in 2013, so we were able to measure to quantity. The weather was characterized by warm and matched precipitation in the growing season (April–July) in 2011 and 2012. Contrarily, the weather was very hot and dry after the late frost in 2013. The Vitalim produced the largest quantity, then the Cumulus and the end of Grolim hybrid. Number of shoot and plant height sequence is identical to the previous one. The Grolim asparagus hibrid has the largest basal diameter.

Comparative Vertical Migration of Three Different Strains of Heterorhabditis bacteriophora and a Single Strain of Heterorhabditis megidis in Sand at 25°C
47-52Views:161Heterorhabditis bacteriophora and Heterorhabditis megidis) were tested for downward migration in 9.5 cm vertical sand columns at 25°C with and without a larva of the wax moth, Galleria mellonella, at the bottom. The number of infective juveniles (IJs) in the upper section decreased since the IJs gradually migrated down toward the Galleria larvae into the lower section of the shell vials. Only the isolate OH 25 behaved differently, because the number of IJs decreased this isolate in the lower section. This isolate was the quickest, since after 12 hrs, most IJs could be found in the lower section of the vials from this isolate. The number of IJs was so small in the lower section that 12 hrs after injection, only the isolates MHG 3 and OH 25 could kill the Galleria larvae.
Besides the fact that mortality occurred among the Galleria larvae with the above isolates, neither IJs nor adults could be detected in either living or dead Galleria larvae 12 hrs after IJ injection. It is noteworthy that the behavior of the isolate Megidis was different from the other isolates: the number of IJs was so negligible in the lower section of the vials that even after 36 hrs none of the Galleria died and, consequently, neither adults nor IJs could be detected after dissecting the Galleria larvae. Each isolate could reach the lower section of the vials, yet only the isolate Megidis could not infect and kill the host. After dissecting the larvae, most IJs and adults could be found in the isolate MHG 3 (95 IJs and adults altogether) 36 hrs after injection. -

Introduction of DNA-based Methods to Agriculture Through Molecular Taxonomic Examination of Poa Species
139-142Views:355biological methods, one among them is AFLP that is well applicable for taxonomic research. Bluegrass species, that are important components of meadow associations, thus their thorough knowledge is necessary in maintaining biodiversity, were examined with bringing this method to perfection.
Taxonomic relationship of the members of Poa pratensis aggregation is a controversial issue. Present study aimes to identify the members of this group, with a developed AFLP method through molecular taxonomic examination of Poa species in meadows nearby Debrecen, revealing their genetical distances. Species of the aggregation show a great genetic variability, but their genetic proximity approves the use of the term aggregation. Results established wider geographical investigation of three species of the aggregation. The distinctness of the species based on their morphological features was confirmed according to their genetical basis as well. The method overall turned out to be appropriate for the taxonomic research of bluegrass species like Poa pratensis and its aggregation. -
Presentation of sales price reserves for live lamb
37-45Views:202Although sheep breeding in Hungary is grounded in strong traditions, its activities only comprise 1% of the total production value generated from agriculture, and 2% of that for animal-based products. The most significant portion of incomes earned in the Hungarian sheep sector has, for years now, stemmed from the sale of live animals. The sector is decidedly export-oriented, as the domestic demand for its main product, i.e. lamb meat, and is minimal, equaling some 20-30dkg per person per year. Part of the sold animals is sold to market as dairy sheep, while the greater
part is sold in the category of lamb carcasses. For this reason, the average weight of slaughter sheep has lied between 19-22 kg for years now. The target markets for live lamb sales are predominately Italy and Greece. In Greece, movement on this market has shown an upward tendency in recent years; noteworthy are also sales to Austria, Holland, Bosnia-Herzegovina and Poland. In 2003, we exported sheep meat in the form of carcasses to Italy, as well as to Germany, and of these exports, 94% went to Italy, while the remaining 6% went to Germany.
Among sheep products, only the trade balance for live animal sales is positive. But even for such producers, only those who are specialized in intensive breeding and those sheep farms “targeting” meat production can obtain earnings. Specialized literature on the sector argues that the quality of Hungarian lamb has diminished dramatically and is beginning to lose its market position. If Hungarian lamb does not meet market expectations, then it will only be bought from producers at lower prices.
My research focuses on those factors which influence price. I separately discuss the question of quality, as one of the most important decisive factors on price. Within this discussion, I describe the market expectations which actually have an effect on the acceptance of live animals for sale on commission. In practice, after the problems of quality, the next most important question is that of when sale is made. In the course of my research, I studied the development of averages for sales on commission of live lambs using statistical methods. The most important problem of this sector is the hierarchical system used in sales: this is the topic hich neither the producer, nor the buyer, wish to discuss, not even with each other. On the basis of the information at my disposal, I outlined the levels of traders and individual levels used to arrive at commission prices. Finally, I examined the components of the production value of live lamb sales. The results I obtained quantified the key role of the prices and the yield, as well as the factors influencing income. -
Using research findings in precision maize production
227-231Views:639The effect of crop production factors on maize yield are examined on chernozem soil in a more than 30 year old long-term experiment on the Látókép Experiment Site of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen. The aim of research is to evaluate the effect of fertilisation, cultivation, plant number, genorype and irrigation. The analysis of the data in the database of the examined period makes it possible to evaluate the effect of maize yield, as well as that of the crop production factors and the crop year, while the correlations and interactions between these factors were also examined. During the examination of the cultivation treatments, it was concluded that the highest yield was obtained as a result of autumn ploughing, but its effect largely differs in the irrigated and the nonirrigated treatments. Based on our examinations, strip cultivation should be applied periodically (e.g. strip – strip – ploughing – loosening) in areas with favourable soil conditions free from compacted layers.
In years with smaller, average precipitation supply or when the precipitation was higher than average, higher plant numbers were more favourable. Under drier conditions, but especially in several consecutively dry years, a lower plant number can be recommended which is not higher than 60 thousand per hectare. In the case of favourable water supply, 70-80 thousand plants per hectare can be used. The yield increasing effect of fertilisation was significant in the case of both non-irrigated and irrigated conditions, but it was much more moderate in the non-irrigated treatment. The extent of weed coverage was significantly affected by the previous crop. In the case of a favourable previous crop (wheat), the weed coverage was significantly lower than after an unfavourable previous crop (maize). In the case of the same previous crop (maize), the extent of weed coverage was mostly determined by the crop year and the extent of precipitation supply. Irrigation is not enough in itself, because if it was not accompanied by intensive nutrient management, yields started to decline.
The results of researhc, development and innovation contributed to the technological method which makes it possible to apply locally adjusted sowing seed, fertiliser and pesticide in a differentiated way, as well as to change the method of operations within the given plot. -
The role of cultivar susceptibility and vineyard age in GTD: examples from the Carpathian Basin
57-63Views:495Grapevine trunk diseases (GTDs) are among the most severe problems in viticulture worldwide. The exact etiology and the role of endophytic microorganisms is not known yet and there is no adequate protection or curative treatment against the disease. Hungarian wine regions are also affected by the disease, and there is restricted information about the rate of infection nation-wide and about the susceptibility of the Hungarian cultivars.
The main objectives of our research are to measure the symptom expression and the damage caused by GTDs, to understand the epidemiology and etiology of the disease to establish a foundation of a proper disease management.
Cultivar susceptibility groups were created with the aim to allocate some Hungarian cultivars and the role of vineyard age was also examined in symptom expression.

Tourism-Based Analysis and Development Potentials in Hortobágy
272-278Views:241Tourism – especially ecotourism and health-tourism – could be one of the sectors which could make Hungary economically competitive after joining the European Union, by ensuring thousands of people employment possibilities, if they take advantage of local and regional opportunities. For this reason, it would be necessary to analyse the two types of tourism mentioned above, as well as to collect data and especially impressions concerning how these potentially lucrative sectors could best be structured and managed, as well as to predict their probable effects.
The most important objectives of my study are to introduce the values of Hortobágy, to analyse the present status of tourism in the Hortobágy National Park, and to make suggestions for increasing the numbers of tourists, by making Hortobágy more attractive.
As a resident of Debrecen, I visited the region several times and took part in programs at Hortobágy as well. I was always curious how the trip to the Hortobágy could be made more enjoyable.
My research was carried out with the help of questionnaires, which were made in three languages – Hungarian, English and German –. In August 2002, I approached foreign and Hungarian tourists in Hortobágy village, and asked them to fill them in. To evaluate the questionnaires, I used Microsoft Excel ’00. During the evaluation, I calculated distribution, arithmetic mean and deviation. Moreover, I obtained the level of significance.
My assumption that tourists visiting Hortobágy are “one-day” tourists, who are visiting the Hungarian Pusta because of an actual program, was supported by my research. I must emphasise that mostly passive tourism opportunities are offered in Hortobágy, where tourist are only external observers of the programs.
In order to change this situation, I suggested that visitors to Hortobágy can be encouraged to stay longer by offering them various programs, in which tourists are actively involved. My program recommendations include a craftsman’s house or tent, where the visitors can try to make typical folk instruments. Moreover, I made suggestions as to how to teach tourists to make Hungarian dishes. I also outlined several one-day program possibilities. Among the opportunities, I also mentioned the need to provide tourists possibilities to spend several days in a conventional Pusta life-style. To realise these things adequate infrastructure and information system should be developed. -
Case study based analyses of economic viability of Hungarian beef farms
184-193Views:245Our country has great traditions in the field of beef production. As early as the Middle Ages, Hungary was known as Europe’s beef exporter. In this decade, production of the Hungarian Grey has increased, due to the popular method of keeping these animals extensively. These animals were even exported to the European markets on foot.
After joining the European Union, this sector of agriculture has been receiving attention due to the major subsidies which were given. Accordingly, numerous farmers have tried to enter this sector of production. However, the power relations have been changed lately, as have the technology used in production, which has undergone several developments. The integrative connections in the sector had been split and also the size of optimal and sustainable production has arisen.
The economic activities must be judged by their effectiveness and profitability, but in most cases their effectiveness can only be seen through such outstanding facts which are independent from the farmer.
I would like to model the economy of a certain enterprise, and the size and the level of its production, through my research under the actual economic circumstances. In my research, I pay special attention to the circumstances which are important in the Hungarian agricultural sector and rural development. -

Genetic diversity study of Hungarian honey bee (Apis mellifera L.) colonies – Previous announcement
61-64Views:616In 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.

Assessing animal species at risk for SARS-CoV-2 transmission: Bioinformatic analysis based on Angiotensin-Converting-Enzyme (ACE2) homology in edible and other animals
127-137Views:513A novel coronavirus called SARS-CoV-2 was detected in December 2019, leading to the COVID-19 pandemic that began in Wuhan, China. This virus is classified as severe acute respiratory syndrome SARS-CoV-2 due to its significant similarities with the SARS-CoV virus. Initially, bats were recognized as the primary animal hosts, but later research indicated that other animals could also serve as reservoirs, posing health risks, particularly for those species consumed by humans. SARS-CoV-2 binds to the angiotensin-converting enzyme 2 (ACE2) as its cellular receptor, utilizing the receptor-binding domain (RBD) of its spike protein, much like SARS-CoV does.
The study aimed to identify animals, particularly edible animals, that may be susceptible to infection by SARS-CoV-2. This was achieved through bioinformatics techniques, including alignment analysis of genomic sequences from selected animals, identity percentages comparison, and phylogenetic analysis based on the interaction between ACE2 and the receptor-binding domain (RBD) of SARS-CoV-2. This analysis identified rabbits, donkeys, alpacas, horses, wild boars, field rats, and monkeys as potentially susceptible edible animals. Additionally, primates were highlighted due to their close genetic resemblance to humans. Overall, 22 animals worldwide were identified as susceptible, marking them as possible reservoirs and hosts for the virus, emphasizing the need for vigilance around animals that humans may contact or consume.

Result of Wine Consumption Survey
387-393Views:244Wine 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.

Study of animal welfare status in dairy cow herds in Hungary – looking for causes of lameness
47-50Views:389In 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.

Using integrated remote sensing methods in the Nagyerdő Natura 2000 area
19-24Views:506The more widely use of GIS, remote sensing technology provides appropriate data acquisition and data processing tools to build several national and international biodiversity monitoring system of environmental protection and natur conservation. The ChangeHabitats 2 is a similar international project, which uses airborne hyperspectral and airborne laser scanning (airborne LiDAR) sources beyond traditional data collection methods to build a monitoring system of Natura 2000 habitats. The goal of our research, on one hand, was to separate the most typical species of trees which can be found in the largest coverage in the research plots of Debreceni Nagyerdő Nature Reserve from field and airborne remote sensing data, use image classification that based on spectral and geometry (height) characteristics of the trees. On the other hand our goal was to evaluate the efficient use of the integration of mobilGIS, airborne hyperspectral and airborne LiDAR data collecting methods to complement or substitut of the traditional, field data collecting methods. We used ArcGIS 10.2 and Exelis 5.0 GIS software for data evaluation, in which the mosaicing, the selection of plots and the spectral image processing were carried out.
