Effects of different crop years and sowing date on maize yield
93-96Views:276We carried out the tests in the flood meadow soil formed on the alluvial cone of Nagykereki, Sebes-Körös belonging to the Bihar plane small region. The aim of the study was to analyse the effect of the different sowing date of maize on the yield trend based on a comprehensive study conducted for 6 years (2007–2012).
The sowing date of maize hybrids is a factor that significantly influences yield, however, its effect is not significant in each crop year. In the years when the date of sowing has a modifying effect, the reliable yield level can be reached with optimal sowing date management (24 April).
The advantage of early sowing (10 April) proved to be dominant in the year of 2012, the seeds were placed into the still wet soil therefore shooting was more balanced. Maize seeds sown at the time of optimal (24 April) and late (10 May) sowing dates were placed into the already dry soil, which deteriorated germination and the strength of early initial development that had an effect on the yield.

Global tendencies in turkey meat production, trade and consumption
83-89Views:723Global meat production totaled 357 million metric tons in 2021. Poultry accounted for nearly 40 percent of total meat production, including 4.2 percent of turkey meat (5.8 million tons). Global turkey meat production has stagnated between 5.5 and 6.0 million tons since 2008, in contrast to the monotonous upward trend in poultry meat production. Turkey meat production generally occurs under well-integrated conditions, with some large multinational companies and smaller, regional players. The industry is exposed to a number of factors that affect supply and demand, including disease outbreaks, government regulations, consumer preferences, and economic conditions. Key factors driving market growth include population growth, urbanisation, and increasing consumer awareness of the health benefits of turkey meat over other meats. In addition, advances in processing, packaging, and distribution technology have improved turkey meat's shelf life and availability, further fueling growth. Turkey farming and production are mainly concentrated in certain regions such as North America and Europe, where industrialisation has a long history and infrastructure is well developed. Turkey meat production in these areas is sufficient to meet local demand and is often exported to other regions. However, in other regions where turkey farming is less developed, such as parts of Asia and Africa, turkey meat production is insufficient to meet local demand. This type of meat must be imported from other regions. The degree of self-sufficiency in turkey meat depends on the level of development of the sector in each region. This study investigates the factors affecting global and regional markets for turkey meat and systematised the development of global consumption, production, and trade of turkey meat.

Conceptional Model of Regional Agricultural Water Management System
199-209Views:458Our study focuses on the water management improvement of the Hajdúsági-löszhát (loess ridge). The Hajdúsági-löszhát (loess ridge) is an intensive agricultural area. At the same time, the problem of increasing water demand is still not solved, so towards of safety production irrigation should be improved. To realise this should be known not even agricultural water demands but industrial and urban ones as well, thus a complex water management system is required to be worked out.
In the first part of the research, the water demand in the area is mapped, then a conceptional model of the Hajdúsági-löszhát’s (loess ridge’s) water management system is created. After collecting data the water management scenario is summarized in a real time model splitted into five periods.
During the research, the instruments of spatial informatics (GIS) are used to get acquainted with the variation of the hydrological parameters in space and time. To understand and simulate the different decision making processes and to choose the right decision alternative, a decision support system is created with the use of spatial informatics data.
In addition, considering the potentially right decision alternative, irrigation will be started in practice, an effect and after-effect inquiry will be made, and the results will be analysed, evaluated and summarized. Finally, a suggestion to the most adequate irrigation technology will be made. -
Genetic diversity study of Hungarian honey bee (Apis mellifera L.) colonies – Previous announcement
61-64Views:385In 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.

Tourism-Based Analysis and Development Potentials in Hortobágy
272-278Views:183Tourism – 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. -
Element content analyses in the Institute for Food Sciences, Quality Assurance and Microbiology
203-207Views:309The role of chemical elements to ensure and promote our health is undisputed. Some of them are essential for plants, animals and human, others can cause diseases. The major source of mineral constituents is food, drinking water has a minor contribution to it, so the knowledge of elemental intake through food is crucial and needs continuous monitoring and by this way it promotes the food quality assurance and dietetics.
With the evolution of spectroscopic methods increasingly lower concentrations could be determined, so the elemental composition of a sample could be more precisely and fully described. Due to the results the gathered knowledge up to the present is supported and new observations can be done helping us to understand such complex systems as biological organisms are.
The quality of a food is determined by the full process of its production, consequently it starts with agricultural production so elemental-analysis usually cover the whole soil – plant – (animal) – food chain, by this way the „Fork-to-Farm” precept is true in elemental analysis field also.
The history of elemental analysis in the University of Debrecen, Centre for Agricultural and Applied Economic Sciences, Faculty of Agricultural and Food Sciences and Environmental Management, Institute of Food Processing, Quality Assurance and Microbiology goes back to 1980s when the so called Regional Measurement Central gave the background for research. The continuous deployment resulted in an obtain of an inductively coupled plasma atomic emission spectrometer (ICP-AES) in 1988, which extended the scope of examinations due to its excellent performance characteristics
compared to flame atom absorption (FAAS) and flame emission spectrometers (FES). The instrumental park retain up to date correlate to the developing analytical techniques due to acquiring a newer ICPAES in 1998 and an inductively coupled plasma mass spectrometer in 2004 – which sensitivity is three order of magnitude better compared to ICP-AES. The Institute supports the work with its own ICP-AES and ICP-MS since 2011. -
Harnessing diversity in durum wheat (Triticum turgidum L.) to enhance climate resilience and micronutrient concentration through genetic and agronomic biofortification
9-20Views:422Huge consumption of wheat-driven food products with low bioavailability and small concentrations of zinc is responsible for zinc-induced malnutrition and associated health complications. The contemporary durum wheat varieties have inherently tiny zinc concentrations in developing grain, which cannot meet the daily human zinc demand. Despite the fact that over two billion people are suffering from iron and zinc-induced malnutrition, various intervention measures have been deployed to reverse the effect of zinc-induced malnutrition on humans. There are evidences that agronomic and genetic biofortification approaches can increase grain yield and nutritional quality (i.e. zinc, iron, protein, and vitamins) of durum wheat to a greater extent. However, there is a lack of direct empirical evidence for which the influence of both biofortification approaches on improving human health. Application of micronutrient-containing fertilizers either in the soil or foliarly is effective in combination with NPK, organic fertilizers coupled with efficient durum wheat varieties, emphasizing the need for integrated soil fertility management (ISFM). Although genetic biofortification is a cost-effective and sustainable approach, agronomic biofortification provides an immediate and effective route to enhancing micronutrient concentrations in durum wheat grain. The application of zinc-containing fertilizers is more effective under drought conditions than in normal growing situations. Hence, this article provides a key information for agronomists and breeders about the potential of biofortification interventions to improve durum wheat yield and enrich the grain qualitative traits to ensure food and nutritional security of the ever-increasing world population.

The future of apple growing in the Northern Great Plain region
35-38Views:334We revealed and assessed those macroeconomic data which enabled us to identify the outstanding role of agriculture and within it that of fruit production. Based on this, it can be said that soil is the most important natural resource of Hungary. The appropriate combination of the additional resources required for production, labour and assets can provide a comparative advantage for the Northern Great Plain Region.
The Northern Great Plain Region is one of the most underdeveloped regions in Hungary, so its development is a political objective. When analysing the economic sectors in the region, the important role of agriculture is obvious and it is also clear that the industry and the tertiary sector can only have an alternative income generating role in the future also. Therefore, it is important that the regional development funds of Hungary and the European Union are directly or indirectly aimed at improving agricultural development and competitiveness. -
Innovation Potential and Regional Competitiveness studies in the Northern Great Plain region
223-228Views:1861.5 million people live in the large region containing 3 counties, which makes it the second most populated region after Central Hungary. Its economy and land use are still defined by agriculture and it has been the least developed region in the country for a long time. In the country this region has the second lowest GDP per capita and employment rate. In contrast to the low values of the economic indicators the region has high potential for innovation. The University of Debrecen is located in the region having one of the widest range of education and intensive research and development is also a characteristic of the region.

Applicability of precision weed detection technologies
163-168Views:420In an agricultural field or horticultural plantation, weeds compete with cultivated plants for water and nutrients. The transpirated water by the weeds is needed to be replaced, which saddles surplus costs on the farmer, which could reduce the profitability of crop production. The aim of the precision plant protection system is to protect cultivated plants by applying site-specific technologies and optimized herbicides combination and methods, without environmental damage. The first step of precision weed control is the scouting for weeds. Traditional and modern (passive and active remote sensing) weed surveying technologies are available to detect weeds. The examination was carried out in an intensive apple orchard with drip irrigation system, protected by hail net of the Study and Regional Research Farm of the University of Debrecen near Pallag. The spectral-based weed detection was worked out by the Tetracam ADC broadband multispectral camera and the GreenSeeker 505 vegetation indexmeter. A strong correlation observed between vegetation indices and weed coverage. Based on the collected data, weed maps are created in appropriate software environment, thus the spatial distributions of the weeds are determined. The species level discrimination and the recognition of weed structural parameters were executed based on the 3D point cloud data by Leica ScanStation C10 laser scanner.

The economic structure and the tertiary ecucation of the function of transformation Hungary 19th and 20th century of in economic integration periods
115-122Views:187Knowledge-intensive businesses sectoral nature of the operation and the specific attributes of the innovation life cycle processes, different needs and different needs induce. These features can also differentiate time that their activities when and what type of resources they require. The availability of capacity in terms of a network co-benefits for those businesses that are creating the possibility that such resources are available to ensure the realization of goals that are not individually owned. These factors and the availability of local availability is also motivated by the small and medium enterprises willingness to cooperate.
Regional supply of resources necessary for the operation of the business of insurance, universities play a key role. The functions of universities in innovation as a business service can be understood as an activity that mediate high added value to other organizations and companies. Questions arise as to the innovative nature of the business industry and sector weights would differentiate whether the R&D&Iintensive areas of expertise.

Perspectives of air cargo activities in case of Debrecen International Airport
131-134Views:256The improvement of Debrecen International Airport has been taking place for more than a decade. The goal is to revitalise the domestic and international aviation of regional centres and connect the Debrecen centred economy zone with other industrial and commercial regions. Considering the market segments of the air cargo industry, and sizing up the requirements of the enterprises, we are seeking to answer for what possibilities an air cargo operation has, and scheduled cargo flights, what alternatives the location of a cargo base has. Getting to know the technical background of ground handling, communication, safety, and security, we can state that the airport is able to handle international cargo aircrafts as well. Regarding to the quantity of frights, we find that there is a possibility of two flights per week. There is minor need of handling dangerous or unique parcels. The surrounding area of working zone is an excellent territory for locating and building cargo facilities, and its technical background. In case of continuously increasing traffic it is suggestible to use the territory behind the apron as a first step of the development. As the activity extends the second step could be the improvement of the southern zone just beside the runway. This way primarily the
scheduled air cargo flights could appear, then as the traffic of commercial scheduled flights increases simultaneously could grow the amount of
small parcel transportation. -
Comparative examination of the tillage systems of maize on meadow chernozem soil
21-24Views:350Maize production plays a major role in the agriculture of Hungary. Maize yields were very variable in Hungary in the last few decades. Unpredictable purchase prices, periodical overproduction, the increasing occurrence of weather extremities, the uncertain profit producing ability, the soil degradation processes (physical, chemical and biological degradation) and the high expenses are risk factors for producers. Due soil tillage, there is an opportunity to reduce these risks. Based on the experimental database of the Institute of Land Utilisation, Regional Development and Technology of the University of Debrecen, Centre for Agricultural and the KITE Plc., various cultivation systems were examined with maize (Zea mays L.) as indicator plant in Jász-Nagykun-Szolnok country in 2012 and 2013. The sample area can be found in the outskirts of Kenderes on a meadow chernozem soil. On the examined plot, strip-tillage, subsoiling and moldboard ploughing were performed, each on 4.5 ha, respectively.
In general, our findings show, that strip-tillage and subsoiling can be alternative tillage systems beside moldboard ploughing on meadow chernozem soils in Hungary.

Mitigation and adaptation measures in the hungarian rural development programme
245-250Views:155In the Hungarian Rural Development Programme (RDP) climate change adaptation is addressed through the measures in Axis 1, 2, 3 and 4. Under Axis 1 farmers can receive support for farm modernisation that will help them adapt to climate change. The processing industry will also be able to use the available resources for capital expenditure on buildings and new equipment. Axis 2 and especially the soil and water package within the agrienvironmental
measure aim to support production methods, which protect soil quality and will help adaptation to climate change. Measures of Axis 3, such as basic services for the economy and rural population, village renewal and development will provide local communities the opportunity to identify actions that can be undertaken to deal with the effects of climate change. On the other hand, the extension of forest resources contributes to climate change mitigation and enhances carbon sequestration. New methods have been elaborated to the sustainable regional water management, irrigation, water regulation, defence against internal water, and soil protection established. Water management contributes to the balance of water quantity on one side, but also to mitigating the climate change on the other. -

The situation and role of higher education in the North Hungary region
91-96Views:204Northern 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.

Virtual Soil Information Systems in the Bihar Subregion and at Tedej Corp
186-189Views:285After evaluating the sample sites’ soils and environmental status, we built up 2 different soil information systems. The first relies on analog data (soil maps), and is based on a regional model; its sample site is the Bihar sub-region. The second is a complex, field scale virtual 3D system, based on several types of data sources. (Aerial photos, GPS, field samples, hyper and multispectral images, soil maps). In this paper, we analyze and evaluate these systems. The greatest advantage of the models is that, with their usage, we can reveal connections which cannot be made by analyzing the individual elements of our data sources. We discovered that with the help of our systems, the monitoring and evaluating of the processes taking place in the soil is more fast and simple.

On the connection between spatial development and sustainable landscape in the Northern Great Plain region
145-148Views:142This paper tries to find connection between sustainable landscape and spatial development policy of the Northern Great Plain region on the basis of specific examples explained in scientific literature. Searching for the common roots of spatial development and sustainability the paper explains two interpretations of sustainability from the view point of landscape, than the most significant element of current landscape change – the polarization of landscapes – will be introduced. This trend in landscape change basically determines the direction of spatial development. This paper analyses the Northern Great Plain region from two different approaches. In the first grouping the region is exposed from the view point of spatial development. In the second partitioning the area is divided into subject matters based on the principles of sustainability and polarization of landscape. This research – analyzing development plans and strategies – considers the current situation within the subject matters.

Evaluation of dry matter accumulation of maize (Zea mays L.) hybrids
35-41Views:868The increase of the grain yield of maize is closely correlated with its seasonal dry matter accumulation. Dry matter is accumulated into the grain yield during the grain filling period. The following maize hybrids were involved in the experiment: Armagnac FAO 490, Loupiac FAO 380 and Sushi FAO 340. In order to determine dry matter content, two samples per week were taken on the following days: 22nd, 25th, 28th, 31st August, 4th, 7th, 14th, 18th, 22nd, 25th, 29th September and 2nd, 6th, 9th, 13th October. In the course of sampling the weight of 100 grains from the middle section of 4 ears was measured in 4 replications. Dry matter content was determined after drying to constant weight in a drying cabinet at 60 °C. Harvesting was performed on 13th October 2017.
The daily precipitation sum was determined by local measurements, while the daily radiation and temperature data were provided by the Meteorological Observatory Debrecen of the National Meteorological Service in Budapest. Among the agrometeorological parameters, an analysis was made of the precipitation during the growing season, effective heat sums during the vegetative and generative phase, and the water supplies. The daily heat sums were determined using the algorithm proposed.
The amount of precipitation in the winter period before the 2017 growing season was 210 mm. The soil was saturated until its field capacity. The rather dry and warm March and April had a favourable effect, but there was no worthy amount of precipitation until May (51 mm) due to the condition of the dried seedbed. Sowing was performed on the 5th of May 2017 in a randomised small plot experiment. There was favourable precipitation and temperature during the growing season, thereby providing ideal conditions for maize development, growth and yield formation. There was near average amount of precipitation in each year. The total amount of precipitation in the summer period is 342 mm. Temperature was mostly above the average, but there was no long and extremely warm period.
The Armagnac hybrid reached its highest dry matter mass 126 days after emergence. Physiological maturity was reached sooner (on the 119th day) in the case of Loupiac, and even sooner in the case of Sushi (116th day). The thousand grain weight of Sushi (which has the shortest ripening period) was 286 g at the time of physiological maturity, while that of Loupiac was 311 g. Compared to Sushi, Armagnac showed 12 g more dry matter accumulation (306 g). In the case of all three examined hybrids, physiological maturity was preceded by an intensive phase, when the dynamics of dry matter accumulation was rather quick. On average, Sushi gained 2.8 g dry matter per day between 103 days following emergence and physiological maturity, while the same values were 3.2 g for Armagnac and 3.3 g for Loupiac. The aim of the regression line slope is to predict the behavior of the dependent variable with the knowledge of the values and characteristics of the independent variables using the regression line equation. Furthermore, to determine how the location affected the dynamic of dry matter accumulation in the Armagnac, Loupiac and Sushi hybrids. In regression analysis, the coefficient of explanation showed that the effect of day in the Armagnac was 97%, in the Loupiac 94%, in the Sushi 90 %. The determination coefficient (R2) is useful in determing how the regression equation fits. But, as we have seen, the determination coefficient alone is not sufficient to verify the model’s accuracy, in addition to the determination coefficient (R2), the normality of the data or the residuals, the variance of the variables at different levels, the independence of the data relative to time and non-oblique. Observations are evaluated for the correctness of the fitted model.
Dry matter values decreased evenly and slightly following physiological maturity. According to our research results, it was established that physiological maturity is followed by a moderate dry matter loss. Until harvesting, Armagnac lost 40 g of its thousand mass weight in 29 days, while the same value pairs were 69 g in 36 days for Loupiac and 29 g in 39 days for Sushi. Loupiac – which had the highest weight at the time of physiological maturity – lost the most of its dry weight; therefore, Armagnac and Sushi had higher values at the time of harvesting.

Renewable energy on animal farms: support system and practical application
13-17Views:224Renewable energy applications were examined in animal farms. The investment support system for animal farms – which has renewable elements – has been summarized through analyzing the legislation and future prospects. The most important in this topic is the Animal Farm Modernization Support, which had several application periods during the 2007–2013 CAP budgets. For analyzing practical application of renewable energies interviews and farm visits have done in Hajdú-Bihar County. The questions covered the general attributes of the farms and the details of the (existing or planned) renewable energy application. In terms of economic analysis saving, the investment return time and the employment effect were examined. The results show wide variety of applied renewable energy application. The investment supports plays great role in renewable energy projects by lowering the return time; and through additional points in application assessing, which is an incentive for farmers to include renewable energy element in their modernization projects.
