Effect of vitamin e and selenium supplementation on the antioxidant content of milk and dairy products in dairy cows
9-12Views:391In 2007, the aim of the Ányos Jedlik program and the call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants - in this case: vitamin E and selenium – used as feed-additives can increase the antioxidant content of milk. The milk with an increased level of vitamin E and selenium content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E and selenium as feedadditives can significantly increase the amount of vitamin E and selenium in the milk and also in the diary products.

Evaluation of the current situation of the Hungarian higher education based on a few indexes
121-125Views:180Around the Millennium we experienced the worldwide development and the growing importance of the role of higher education played in the social and economic development. A few years later, however, a crisis appeared in the situation of higher education (Kadocsa, 2002). The Hungarian higher education system faces the perspective of serious changes in its fundamental principals – such as its main activities and the economical ways which are used to finance these activities – even if only parts of the new educational scheme come into effect. Considering this fundamental activity aspect of the issue, there are new challenges which make necessary to rethink the role and aim of higher education and to define the new tasks needed in connection with education, research and other services. Hungarian Education needs to be renewed and improved to avoid a complete
break away; therefore, future priorities and tasks in order to fulfill these priorities need to be defined (Vincze and Harsányi, 2011). The new conception seems to be based on restrictions of the budget as it is experienced recently: a new structure available for a smaller part of society with a restricted budget has been under development. However, not even a battle, let alone a war can be won without money, horses and arms. The recent financial restrictions as well as the parts of the Széll Kálmán plan concerning education prove that serious amounts of governmental funds is taken away from education. The international improvement tendencies contradict to basically all of these Hungarian priorities.
All in all, no reform or change – no matter how much wanted – can be achieved without appropriate funds. -
Cohesion and competitiveness of the European Union at strategic level
29-33Views:217After the relaunchment of the Lisbon strategy, the cohesion policy of the EU concentrates even stronger on the establishment of the knowledge based economy, on R&D activities and innovations. In the first chapter I demonstrate the funds division of the convergence and regional competitiveness targets in the financial perspective between 2007–2013. The first sheet shows unambiguously that the new member states from Middle-Eastern Europe and the Mediterranean countries spend their funds on convergence and cohesion issues. The situation is contrary in the highly developed Western-European countries, in the core regions, where decisive part of the funds are spent on competitiveness issues. In the second chapter of the study I present the Europe 2020 strategy of the EU, that is a crucial paradigm change in the European strategy-making. While the Lisbon strategy focused on the social cohesion of the European Union, the Europe 2020 strategy strives the fostering of the European competitiveness. In the third part of the study I make a comparison how the funds-allocation altered during the two financial perspectives.

Sensitivity of methods for estimating reference evapotranspiration
51-56Views:364The knowledge of the evapotranspiration of natural ecosystems and plant populations is of fundamental importance in several branches of science, research topics and practical uses. Nevertheless, the harmonization of the large number of methods and the changing user needs often causes problems. Sensitivity analysis of 10 ET0 estimation models and model variants was performed. Magnitude of the obtained outputs and the changes triggered by each atmospheric parameter were evaluated. The objective of the analyses was to get to know the sensitivity of the different models and to select the most accurate and the most suitable ones for adaptation to local circumstances. Therefore, it becomes possible to achieve as high accuracy as possible in applications which need ET0 estimation.

Examination the stresseffect of litter’s let-together system (“kindergarten”) by measuring faecal cortisol metabolites of sows and piglets
87-90Views:407Piglets in commercial intensive pig husbandry are often abruptly weaned between 3 and 4 weeks for economic reasons. The process of weaning is a multifactorial stressor, in which nutritional, social, physical and psychologic stressors are combined. Piglets are often exposed to unfamiliar piglets around weaning which results in a period of vigorous fighting. Stress plays an important part in welfare research. Traditionally glucocorticoids are measured in blood samples but their use is often limited as the act of sample collection may stress an animal. Measurement of faecal cortisol/corticosterone metabolites is a non-invasive method for evaluation adrenocortical activity. The aim of this study was to examine the effect of litter’s let-together system (“kindergarten”) in the farrowing house by measuring faecal cortisol metabolites. According to our results the “kindergarten” system has no stress effect on sows and piglets, respectively.

Milestones in the development of agronomic management practices in crop production
203-209Views:283From the dawn of the history of the human race, agriculture has always been a profound activity of mankind producing food and feed as well as various plant originated materials for further processing.
Agronomy, like any other human activity, depends on the perpetual development of knowledge and technical skills, - in a modern context – science and innovation. This paper is intended to provide the reader with information regarding the main phases of the development of agricultural production from the Neolithic societies through the early Mesopotamian and Egyptian empires to the inventions of first organised learned society of Rome. The major research findings of the past two millennia including agro-chemistry, genetics and technical development are presented.
Such a review should not lead to any scientific conclusions, but rather a philosophical postulate similar to that of Jonathan Swift written some centuries ago: “And he gave it for his opinion, that whoever could make two ears of corn, or two blades of grass, to grow upon a spot of ground, where only one grew before, would deserve better of mankind, and do more essential service to his country, than the whole race of politicians put together”.

The applied mechanical equipments for wastewater treatment in the észak-Alföld region
171-178Views:260In this study we presented the results of a survey research, which was performed during 2015 at 34 sewage treatment works, operating in Észak-alföld region (Hungary). The survey focused on applied mechanical equipment and works of art of the sewage treatment establishments.
The results of the survey showed that the majority of the examined sites (approx 65%) are working with capacity utilization of 50–100%,merely the 12% of plants was overload. It was found analyzing of specific energy consumption of the sites that the largest value (1.1 kWh per m3) was at the plants with smaller capacity (0–1000 m3 per day). It was clear during the questionnaire processing of the survey that almost all of the works applied activated sludge for sewage treatment The sludge treatment of the sewage plants is conducted by two methods; aerobic- and mixed (anaerobic and aerobic) sludge stabilization. We suggest for the plants with small capacity to use deep aerators, since anachronistic method used the at 3% of the settlements.

The impact of population management on urban and rural Hooded Crow populations
119-123Views:326Hooded Crow (Corvus cornix), originally native to agricultural areas, has become widespread in urban areas in recent decades. However, this process has negative consequences on urban animals and humans. Due to these problems, the control of urban crow populations is needed. Crows also cause significant damage to wildlife management, and are constantly being controlled in rural areas as well. In this study, we compare rural and urban populations to find out whether hunting activities have a population reduction effect. In the rural population, the reduction is carried out by weapons and traps, while the urban crows are controlled using traps only. In both sample areas, crow nests were surveyed during the nesting period. 29 active nests were monitored in the rural area in 2021, and 39 in 2022. In the urban area, 44 nests were recorded in 2021 and 35 nests in 2022. In 2021, 30 individuals were removed in the rural area, and 84 in 2022. In the urban area, 223 individuals were removed in 2021 and 144 in 2022. Results show that the number of crows removed follows the number of active nests, so that the reduction of a given year is likely to have an effect on the following year's nesting population. Because traps mostly capture juvenile birds, reducing the breeding population in the city can only be achieved in the long-term. Considering this, it is likely that increased attention to population control can effectively maintain crow populations and reduce the problems they cause.

Data on the Orthoptera fauna of characteristic agricultural landscape in the Carpathian Lowland
25-34Views:406Orthoptera fauna and assemblages of natural and semi-natural grasslands of the Hungarian Lowland are well-known, however, little is known about assemblages living in agricultural and anthropogenic habitats such as arable lands, roadsides, hedges, and riverbanks. Due to climate change, intensification of agriculture, and change of habitat use, these habitat types become increasingly important.
To collect data on these mainly unknown habitat types, a three-year study was carried out on the Orthoptera fauna and assemblages of the firth region of the Tisza and Sajó rivers. This area was mainly unknown, and our research contributes to increasing knowledge and provides a base for further investigations.
In the 40 sampling sites of the studied region, an occurrence of 30 Orthoptera species was recorded based on 2241 sampled individuals. In this study, we provide 540 new distribution data records of orthopterans that means an almost eightfold increase of the known data. Orthoptera assemblages of different agricultural habitat types showed significant differences considering both species richness and composition. Data suggested that non-cultivated habitat patches of dirt-roads, roadsides and stubble fields and even extensively used pastures, hayfields and alfalfa, red clover, and even wheat fields can preserve relatively species-rich Orthoptera assemblages. Contrary weedy sites of these cultivars and intensively used arable lands (maize, sunflower and rape fields) showed extremely low species diversity.

Ecological Conditions of Agricultural Land Use in Transcarpathia
190-194Views:214The unbalanced anthropogenic effects for several decades resulted in significant technogen damages in the ecosystem of Ukraine. Excessive land development, including the use of slopes, effected the disintegration of the natural balance of lands – arable-lands, meadows, forests, and watershed areas – producing quite a negative effect on the landscape’s nature itself. It has to be stressed that according to other indexes, too, agricultural lands show a tendentious deterioration.
Erosion, caused by water and wind, is one of the most influential factors in the degradation of agricultural soils and in the reduction of the productiveness of benefital lands. Nowadays the degree erosion became significant and it directly endangers the existence of the soil which is a principal chain-link of the agricultural cultivation as well as an irreplaceable element of the biosphere.
The social and political changes in Ukraine’s life demand fundamental modernization in the land utilization both in ecological and in economical aspects. However, these aims can be realized only if, during the developments, we base on the up-to-date results of agronomics, and we do further research in the relations of agricultural land use and environmental protection. According to the latest theories, rational and environmental-safe agricultural production relates to the optimum correlation of the natural- and agricultural- ecosystems as well as to the reconstruction of agricultural areas built on the basis of environmental protection. -
Production of novel fermented milks
303-305Views:287The objective of this research was to test the influence of various natural substances on acid production, growth, and viability of characteristic microorganisms in yogurt and probiotic fermented dairy foods. Oligofructose, inulin, honey, and the dried biomass of Spirulina (Arthrospira) platensis were found to stimulate the growth rate and acid production activity of the major thermophilic diary cultures tested and, in addition to this, the presence of the aforementioned substrates also improved the survival of starter bacteria in fermented milk products during storage. The reduced production time of cultured milks resulted in increased production efficiency. The stimulatory and/or protective effect of oligofructose,
inulin, honey, and Spirulina on Bifidobacterium spp. is probably the most important finding of this study because bifidobacteria do not grow well in milk and they have low survival rates in conventional fermented milks. Some of the bioactive substances tested were also capable of exerting an antifungal effect on spoilage yeasts and molds, and improving the nutritional and sensory properties of the final product, thus providing a new opportunity for manufacture of functional fermented dairy foods. -
The production and financial achievement of the agricultural co-operatives in 2002-2007
21-28Views:215The aim of the study was the examination of the achievement of the Hungarian agricultural enterprises – special regard to the agricultural co-operatives – based on the aggregated database of Hungarian Tax and Financial Control Administration (APEH), from the database of the Research Institute of Agricultural Economics. From the methodological aspect plain statistical devices were used, indicators for corporate analyses were
calculated and analyzed for the time series. One important conclusion is that the socio-economic weight of the agricultural co-operatives was strongly decreased in the period after the EU accession. The other important statement is that over the general examination of economic actors on an aggregated level the comparative analysis of the single enterprises forms would be needed. In the case of the co-operatives the separated examination of the former type producer co-operatives and the new type co-operatives would be necessary -
Contexts between apple orchards with various cultivar comparisons and the effect of ATS (ammoniumthiosulphate) on fruit thinning
35-38Views:271Our research focuses on a fruit thinning material that can also be used in apple production. This material reduces significantly the required manual labor of hand thinning by russeting the blossoms selectively. The ATS (ammonium-thiosulphate) acts as chemical desiccant contrary to the nowadays commonly used materials such as naphthalene acetic acid, naphthyl acetamide, benziladenin and ethylene, which affect the metabolic processes of the plant by regulating the hormone system. In our experimentals cultivar ’Pinova’ and ’Golden Reinders’ were treated with different concentrations of ATS. The effect of these doses on the fruit setting and the quality and quantity parameters of the fruits was studied. According to our results, in the case of cultivar ’Pinova’ the ATS did not have any detected effects at the concentration of 1.5%. Application of ATS at 3% decreased considerably the fruit setting and fruit yield, accordingly the mean fruit size improved. The response to treatment in the case cultivar ‘Golden Reinders’ does not have any similar consistent results.

Effect of the media on morphology of Cryphonectria parasitica (Murr.) Barr isolates and their Vegetative Compatibility Groups
38-42Views:477The most dangerous pathogen for the European and American chestnuts is the blight fungus Cryphonectria parasitica (Murrill) Barr. Short after its introduction a big number of chestnut trees were destroyed on the infested area. The control could be really complicated, because of the numerous vegetative compatibility groups of the fungus. There is a type that carries a mycovirus viz. hypovirus in the cytoplasm. We are able to control effectively this pathogen by using mycovirus-carrying strains (called hypovirulent fungal strains also). In laboratory it is easy to multiply the virulent and the hypovirulent strains of the fungus but do not easy to differentiate colonies visually on simple PDA medium. During our research, we tested different types of media, based on potato and chestnut bark extract respectively. It was observed that on potato medium the virulent strains produce more orange pigments. So it is more easy to differentiate virulent or hypovirulent isolates of chestnut blight fungus based on colony colour and morphology.

A morphological survey of Ustilago trichophora, a smut fungi and evaluation as bioherbicidal agent for barnyard grass (Echinochloa crus-galli)
91-93Views:324Ustilago trichophora (Link) Kunze is a widespread smut fungus in all over the world. This fungus is pathogenic on species of Echinochloa genus. The subject of present research was that smut fungi occurrence on barnyard grass (Echinochloa crus-galli). Numerous barnyard grass plants with symptoms of smut galls caused by Ustilago trichophora on stems were collected from two counties, víz. Hajdú-Bihar (East-Hungary) and Jász-Nagykun-Szolnok (Middle-Hungary). The infested plants were examined in laboratory, which included the observation of the symptoms and the morphological properties of the spores and the colonies developed from sporidia. The results suggested that this fungus could be effective against barnyard grass weed so the biological control of this weed plant (Echinochloa cruss-galli) can be managed by using Ustilago trichophora biopreparates. As Ustilago trichophora can produce abundant sporidia in liquid culture, a high effectiveness control should be apply by Ustilago trichophora smut fungus as a mycoherbicide in Echinochloa weed control.

Analysis of different fertilization settings’ effect in the case of the summer savory’s (Satureja hortensis L.) yield and active agents
101-105Views:310During our research we investigated the Mediterranean summer savory’s (Satureja hortensis L.) nutrient requirement with different fertilization settings in a small plot trial. We measured the medicinal plant’s raw and dry drug mass, and the presence of the main essential oil active agents under the different fertilization settings using SPME (Solid phase microextraction) and GC-MS (Gas Chromatograph mass spectrometer).From the drug’s raw and dry mass perspective, based on the obtained results, in our opinion, the N30P40K60 nutrient requirements were ideal in 2015, while the N60P80K120 nutrient requirement showed the best values in 2016. A significant relationship is assumed between the different fertilization settings and the essential oil active agents’ distribution. During the analysis of data, we compared three of the savory’s essential oil active agents’ percentage of presence in the nutrient requirement samples. -
Comparison of Variability among Irradiated and Control Inbred Maize Lines via Morphological Descriptions and Some Quantitative Features
70-73Views:259Knowledge of genetic diversity in breeding material is fundamental for hybrid selection programs and for germplasm preservation as well. Research has been done with nine irradiated (fast neutron) and four non-treated inbred lines. The aims of this study were (1) to investigate the degree of genetic variability detected with morphological description (based on CPVO TP/2/2) in these materials, (2) to compare the genetic changes among irradiated and non-irradiated maize inbred lines (based on some quantitative features). The irradiation did not change any of the characteristics clearly in positive or negative way, which can be related to the fact that the effect of induced mutation on genetic structure cannot be controlled. From the irradiated lines we have managed to select plants with earlier ripening times and better phenotypes. We could distinguish 3 main groups by the morphological features; these results match our expectations based on pedigree data. Markers distinguishable on the phenotypic level (e.g. antocyanin colouration, length of tassels) were significant in all lines.

The effect of nickel-contamination, nitrogen-supply and liming on the chemical composition of perennial ryegrass (Lolium perenne L.)
85-92Views:219Plant-production is determined by many production-factors. Each of these factors became subject of research-works through the years, still we state, that studying their interaction is even more important. For studying these interactions we set up a potexperiment, within that the direct effect and the interactions of four factors was inspected: soil, nitrogen-supply, nickel-loading and liming. Experiments were carried out on two soil types with extremely different characters: one was a chernozem soil with good fertility and buffering capacity, the other was a shifting sand soil with low humus-content and buffering capacity. Nitrogensupply and liming was added on two levels, while nickel on three within 12 combinations on each soil types. Plant production was cut two times within the vegetation period. The amount of production and dry matter was weighted, fractured and their element-content was measured by an ICP-detector.
Ca-content on the shifting sand soil was determined by all three factors, however the interaction between nickel-loading and liming was also significant. Nitrogen and liming increased Cauptake, that is due to appropriate nutrient-supply and improvement of a better pH-value. On the chernozem soil nitrogen and CaCO3 also increased the Ca-content. This is caused by a better nutrient supply and a higher amount of available Ca-ions.
On the shifting sand soil nickel content was increasing parallel to higher nitrogen-dosages. In presence of higher nickelamount the nickel-content of plants was also increasing, still according to liming, this increment was different. On the chernozem soil nitrogen a nickel increased Ni-uptake. However, liming also had a positive effect on Ni-content, that can be explained by the high amount on colloids in the soil, the adsorption of Ni-ions on them and in presence of liming material the replacement of Ca-and Ni-ions.
The potassium-content on the shifting sand soil was different in each liming-combination. In combinations without nickel the potassium-content of limed and not limed combinations was on the same level. In not limed combinations by adding nickel potassiumcontent was increasing, while in limed combinations no change was observed. On the chernozem soil by adding liming material the amount of uptaken potassium was decreasing, that is due to the antagonism between Ca- and K-ions. -
Nutritive value of Timothy (Phleum pratense L.) during primary growth in 2005
61-67Views:347In this paper we analysed the change of the chemical composition and nutritive value of Timothy observed during the spring of 2005. The nutritive value of Timothy was observed between the end of April and the beginning of June relating to the following parameters: crude protein, crude fibre, crude fat, ash, N-free extract, net-energy growth, net-energy lactation, net-energy maintenance, Metabolizable Protein Energy dependent, Metabolizable Protein N-dependent. We also analysed whether a relationship between the environmental factors that affect the
growing period of grasses and the chemical composition can be detected or not. While testing for correlation, the number of days from 1st January, the amount of heat accumulation, solar radiation and rainfall were considered as independent coefficients.
For the estimation of weather conditions we calculated the climate index. The observed year can be described as a year with a rainfall above the average and abundant solar radiation. A correlation can be detected between the change of parameters of nutritive value and the quality of the current year. In 2005 the result of the analysis of nutritive value was showed a significance difference with respect to each chemical composition at the rate of P<0.001 depending on the time when the samples were taken.
According to the outlined data it can be stated that the change of the value of crude protein and ash show decreasing tendency agreeing the research literature. In parallel with the change of nutritive value, the amount of crude fibre and N-free extract increased. However, the value of Net-Energy maintenance showed an alteration only in the first half of the observed period. The same alteration tendency can be detected in the Net-Energy growth and the Net-Energy lactation. -
Site and hybrid-specific agrotechnical models in sweet corn production
105-108Views:203The effect of three agrotechnical factors (sowing time, fertilization, plant density) and two genotypes on the crop yield of sweet corn was examined on chernozem soil in the Hajdúság region in two different crop years. Compared to the 30-year average, the climate was dry and warm in 2009 and humid in 2010. The experiments were conducted at the Látókép Research Site of the University of Debrecen. In the experiments we applied two sowing times (end of April, end of May), six fertilization levels (control, N30+PK, N60+PK, N90+PK, N120+PK, N150+PK) and two crop density levels (45 thousand ha-1, 65 thousand ha-1). The hybrids we used were Jumbo and Enterprise. As regards the requirements of sweet corn production, the crop year of 2009 was dry and warm. The effect of moisture deficiency was more adverse on the crop yields with the second sowing time. On the contrary, the other examined year (2010) was significantly humid; the precipitation was 184 mm above the 30-year average and the temperature was average.
In the dry and hot crop year, the best yields were obtained with the hybrid Jumbo (25677 kg-1) at 65 thousand ha-1 plant density level on the average of the fertilization levels. The crop yields of Enterprise were also the highest at high plant density level (24444 kg ha-1). With the second sowing time the highest yields were obtained at the higher plant density level (65 thousand ha-1) with both hybrids (Jumbo 18978 kg ha-1, Enterprise 18991 kg ha-1), which confirmed the good adaptation capability of these hybrids at high plant density level. In humid crop year with early sowing time the highest yielding hybrid was Enterprise (at 45 thousand ha-1 crop density level 20757 kg-1), at the same time, Jumbo was best yielding at the higher plant density level (18781 kg-1). With the second sowing time the highest crop yield was obtained with Enterprise again (20628 kg ha-1 at 65 thousand ha-1 plant density level). With this sowing time the average yields of Jumbo, was 18914 kg ha-1 respectively. We found that dry crop year and early sowing time provided the best conditions for sweet corn production; the highest yields were obtained under these circumstances, which might be the results of the outstanding water management of chernozem soils. -
Mapping agricultural performance and environmental parameters aimed at generic regional studies
29-34Views:517In this paper we present the interim results and the methodology applied to create web GIS ready cartographic representations of agricultural performance related information and environmental parameters. The main aim of the research is to eventually create a web GIS based decision support system that can enable decsision makers and general users to create useful and representative map layouts of certain environment and agriculture related phenomena that can be easily analyzed and interpreted to make strategic decisions on environmental issues. In this aim the initial steps are to evaluate the available data for cartographic representation, analyze the possibilities of visualization, create a GIS ready data structure and implement the database and revise additional possibilities to incorporate further environment related datasets of auxiliary sources. The main results of the study are a comprehensive set of visual layouts that could serve as guideline for mapping statistical information of agriculture and some steps towards the incorporation of environmental parameters to the system.

Competitiveness of the biomethane opposite with the CHP technology of biogas by definite plant size
5-9Views:213The biogas sector has never before aroused so much attention as it does today. Combined heat and power (CHP) reliable and cost-effective technologies that are already making an important contribution to meeting global heat and electricity demand. Due to enhanced energy supply efficiency and utilisation of waste heat renewable energy resources, CHP, particularly together with district heating and cooling (DHC), is an important part of national and regional Green House Gas (GHG) emission reduction strategies.
During my work I am going to use the basic data of a certain biogas plant than I assemble one model from that. Against the CHP technology I am going to plan a biogas cleaning-equipment. During my research it revealed, that in the case of a 1 MW output power plant it is not worthy to deal with biogas cleaning between national conditions. Investigating the quantity of heat recovery in the CHP technology it is obvious, that the net income at 1 m3 biogas is at least 72 times more than the cleaning technology (heat recovery is 0%).

Comparative analysis of Carpathian Braunvieh’s morphological traits
15-19Views:611The Carpathian Braunvieh cattle established by the cross-breeding of the Schweizer Braunvieh and the local breeds of the Carpathian basin approximately 150 years ago. The evolved three usage breed was durable and resistant, however in comparison with the high-productivity breeds was less competitive. The dramatic lay-off, and the endangered status of the breed requires a conservation programme. University of Debrecen took the investigation of the Hungarian population and it’s detailed genetic studies. Within this research project among others we carry out body measurements and rates of the body traits. Depending on these results, we may decide on the subsequent gene-reserving objects. Based on body measurements and live weight we established that the breed at Mikóháza favours to the one lived in Hungary in the 1960’s, and to another, named Ukrainian Carpathian Brown. Compared to the earlier data (Horváth, 1966) smaller body traits can be seen. Our livestock is proportionately smaller than the other breeds in height at withers, as well as in live weight. Based on the comparative analysis, we established, that – thanks to the aware sorting – the imported individuals represent the ancient, primitive Carpathian variant.

Examination of lead absorption ability on chernozem soil and the observation of the accumulation effect of Lactusa sativa L. in pot experimentation
101-104Views:333In our research a chernozem soil sample formed on loess was collected from an area under cultivation. Our aim was to determine the lead adsorption capacity using a soil column experiment. The study showed saturation of lead content of the soil. The lead accumulation capacity of Lactuca sativa L. was measured in the sections of roots and leaves applying pot experiments. It could be observed that the lettuce accumulated lead easily from the chernozem soil. The lead content was increased in the analyzed sections of the plants against an increasing lead content.
