    We can find more and more references on the importance of sulphur and sulphur fertilization, mainly in the case of most important field crops, as cereals, maize, and the oilseeds. The traditional sulphur sources continuously lost their importance by the stringent air pollution orders and nowadays they are not able to meet the demands of plants. Besides, the application of superphosphate, as phosphorus mineral fertilizer, decreased in several countries. Sulphur fertilization is required in most cases to reach the required yields and quality parameters. The lack of
    sulphur causes decreased nitrogen utilization and yield by cereals as winter wheat, moreover, results less favourable baking parameters.
    We have examined the N and S content of different parts of winter wheat plants in a small plot experiment at the University of Debrecen, Centre of Agricultural Sciences, Látókép Experimental Station. We have also studied the effect of different sulphur fertilization forms and doses on the baking quality parameters and yield. Our aim was to contribute to the development of yield and quality improving sulphur fertilization methods, adaptable by practice.
    We have measured the lowest yield in the case of one of the control plots, and 100 kg/ha nitrogen, 80 kg/ha potassium and 70 kg/ha phosphorus nutrient supply resulted the lowest yield (8.7 kg/plot). The maximum yield, 10.2 kg/plot was also experienced on superphosphate fertilized plot by the application of 140 kg/ha phosphorus dose. Application the first dose of both Biofert and FitoHorm 32 S leaf fertilizers raised the yield from
    9.1 to 9.9 kg/plot. ANOVA proved that Biofert and FitoHorm 32 S had no significant effect on the amount of yield, the increase is only a tendency.

    Maize is currently the single raw material of bio-ethanol production in Hungary. The aim of our examinations is the observation of yield and
    nutritional characteristics of commercial maize hybrids in Hungary from the aspect of efficient bio-ethanol production. We set up a 
    randomized block field trial. We determined the starch content and starch yield (t ha-1) of the 51 maize hybrids involved in the field trial.
    In laboratory conditions, we examined the amylose and amylopectin ratio and the amount of resistant starch of the selected 20 maize hybrids.
    According to our results, there is a significant difference between the starch yield the amylose component of the starch content and resistant starch of the examined maize hybrids. Our studies reveal that maize as a raw material must be selected based on the cultivation objectives. If the objective is bio-ethanol production, detailed knowledge of starch content is necessary. There is a significant difference among commercial maize hybrids in Hungary in terms of characteristics determining the producible amount of bio-ethanol.

  • Development of an InDel marker set to establish hybridization between wild boar and domestic pig (Sus scrofa) breeds

    Wild boar and domestic pig breeds belong to the same species (Sus scrofa), so they can easily have viable offspring. This could be a problem in preserving the genetic lines of wild boars, keeping clean the food industry from lower-grade hybrid boar meat, and „producing” ethically questionable trophies, too. The aim of our study was to develop a cost-efficient, fast, easy and accurate marker set which can separate the wild boars from hybrids and domestic pig breeds.

    The InDel markers were developed using 59 full pig genomes of 17 different breeds (e.g. Duroc, Large White, Landrace, Mangalica, wild boar). Sequence differences between the genomes of wild boars and domestic breeds were identified in variant call files, and verified using the IGV software. Wild boar, mangalica and duroc specific primers to amplify the chosen InDel regions were designed using Primer3.

    After preliminary tests five markers were chosen, three wild boar specific, one Mangalica specific and one Duroc specific one. Fluorescently labelled primers were used to make the valuation easier and more accurate with capillary electrophoresis instead of gel-electrophoresis. The markers were optimised individually and in multiplex conditions and tested in samples of 11 breeds.

    In conclusion, a new, faster and cheaper set was developed to separate the wild boars from the hybrids and domestic breeds. Based on the preliminary testing on wild boars, duroc and mangalica breeds zero samples resulted false negative, so it is 100% accurate. In addition, it is a much more cost- and time-effective way than testing every single sample with STR sets.

    The agricultural environment is contaminated with heavy metals and other toxic elements, which means more and more threats. One of the most important toxic element is the arsenic (As).
    The objective of the study was to investigate the effect of As-treatments on the element content of the different parts of the green peas (root,stem, leaf, pod, pea) in the 4. phase of the plant development. Plants were grown in green house. Arsenic was applied in a form of arsenate (As[V]) and the plants were treated with 0, 3, 10, 30, 90 and 270 mg kg-1 arsenic.
    According to the results the Ca content of root and pod was increased in the case of the 3 mg kg-1 As-treatment, after that decreasing tendency was observed. In the case of the 270 mg kg-1 As-treatment, the Ca content in the root was increased, because some element is able to concentrate in the lower biomass. The Ca-content of stem and leaves was reduced when the plants were treated with more than 30 mg kg-1 As. The lowest As-treatment (3 mg kg-1) increased the Na content in the root, stem and leaves, however in the case of the higher As-dose, decreasing tendency was observed. In the case of the generative plant parts the 3 mg kg-1 As-treatment also increased the Na content, nevertheless in the case of the higher As-treatments lower Na content was measured, however in the case of the highest As-treatment (270 mg kg-1) the Na content was increased in the generative plant parts, probably the Na was concentrated in the lower biomass. In the case of the 90 and 270 mg kg-1 As-treatment the Mo-content also was increased in the generative plant parts. The 270 mg kg-1 As-treatment caused a similar tendency in the case of the generative plant parts as a result of the lower biomass. In the case of the pod and leaves, the lower As-doses did not cause significant changes.
    The Mo content was increased in the root and pea when the plants were treated with 3 mg kg-1 As, but in the case of the higher treatments it was decreased. In the case of the stem it was reverse, the lowest As-tretament (3 mg kg-1) decreased, nevertheless the further As-doses increased the Mo content.

  • Effect of dietary arginine on organ weight and feed intake in Japanese quail (Coturnix japonica)

    This study showed the effects of different dietary arginine levels on organ weight and feed intake in growing Japanese quail. Quails were provided with diets containing low, control, or high arginine for a fourteen-day experimental period. Dietary arginine levels had no significant effect on relative liver weight in both sexes, whereas low arginine intake was associated with increased relative brain weight. These findings suggest tissue-specific responses, with the liver exhibiting metabolic resilience and the brain being preferentially maintained under nutrient limitation. Feed intake was reduced under low dietary arginine during the second week, indicating sensitivity to arginine availability at this developmental stage. Variations in feed intake across studies suggest that arginine’s effects are context-dependent, influenced by physiological status, environmental conditions, and baseline diet composition. Overall, our findings highlight the role of dietary arginine in organ weight and feed intake, reflecting both direct effects on organ development and indirect effects through feed intake regulation.

    Bamboo plants are currently attractive to researchers because of their versatile uses. Understanding the bamboos’ genetic level is needed to develop new varieties. Taxonomic identification is the basis for plant development. Bamboos were identified as their taxonomical morphological characters which are dependent on environmental factors. Molecular Marker techniques can be used to perform accurate genotype identification, which can be used for genetic diversity analyses. The RFLP, RAPD, AFLP, SSR, ISSR, iPBS, SCARS, SCoT, SRAP marker systems have been shown to be able to efficiently determine the genetic diversity of bamboo species based on genotyping. This paper summarizes research that aims to analyze the genetic diversity of bamboo species on a molecular basis.

    Combining ability estimation is an important genetic attribute for maize breeders in anticipating improvement in productivity via hybridization and selection. This research was carried out to investigate the genetic structure of the 27 F1 maize hybrids established from nine lines derived from Maize Research Department and three testers, to determine general combining ability (GCA), determine crosses showing specific combining ability (SCA) and superiority percentages for crosses. Nine lines, three testers, 27 F1 hybrids and two check commercial hybrids (SC162 and SC168) were studied in randomized complete block Design (RCBD) with three replications during 2016. The results of mean squares showed that significant and highly significant for most studied traits (days to 50% tasseling, days to 50% silking, plant and ear height, ear position, ear length, no. of kernels per row, 100-kernel weight and Grain yield). Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. Lines with the best GCA effects were: P2 (line 11) and P6 (line 21) for grain yield, for testers Gm174 and Gm1021 had significant GCA effects for grain yield. The hybrids P5×Gm1021, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1002 had significant and negative SCA effects for grain yield. Crosses P1×Gm174, P2×Gm1002, P5×Gm1021, P6×Gm174, P6×Gm1021, P7×Gm1021, P8×Gm1002, P9×Gm1021 were the best combinations manifested and significant superiority percentages over than check varieties (SC162 and SC168) for most studied traits. Therefore, these hybrids may be preferred for hybrid crop development.

    Genetic manipulation may not replace any conventional method in crop breeding programs, but it can be an important adjunct to them. Plant regeneration via tissue culture is becoming increasingly more common in monocots such as corn (Zea mays L.). In vitro culturability and regeneration ability of corn decreased as homozigosity increased, which suggested that these two attributes were controlled primarily by dominant gene action. Pollen (gametophytic) selection for resistance to aflatoxin in corn can greatly facilitate recurrent selection and screening of germplasm for resistance at a much less cost and shorter time than field testing. Integration of in vivo and in vitro techniques in maize breeding program has been developed to obtain desirable agronomic attributes, speed up the breeding process and enhance the genes responsible for them. The efficiency of anther and tissue cultures in most cereals such as maize and wheat have reached the stage where it can be used in breeding programs to some extent and many new cultivars produced by genetic manipulation have now reached the market.

    After 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.

  • The impact of employment and income circumstances on the development of regions

    The economic condition of an area is fundamentally determined by the extent of employement, as well as the size and composition of its active population. No sustainable economic growth is possible without the necessary amount of employees with the proper skills.

    As regards the proportion of employees, i.e. economically active people is significanlty lower in Hungary than not only in Western Europe, but also countries which joined the EU recently. One of the reasons for this fact is the low amount of part-time employment and the other is the phenomenon that the number of agricultural employees – who had a significant role – greatly decreased in the county.

    The employment level of the population in the county is nearly identical as that of the North Great Plain region and it is lower than the country average. The activity proportion, i.e. the joint proportion of employees and unemployed people in the population between 15–74 years of age is 3 percentages lower than the country average. The proportion of unemployed people greatly varies depending on the small regions of the county. The proportion of registered unemployed people in the population of active age is the lowest in Debrecen and the highest in the Hajdúhadház small region. The unemployment of career-starters is a further problem to deal with.

    The composition of employees in the county is different than the country average. When compared in terms of different economic sectors, it can be observed that agriculture, game management, forestry and fishery are more significant than the country average. Of the provider sectors, the proportion of financial activity, real estate matters and economic services is lower, while that of accommodation services and hospitality is higher than the country average.

    There are regional differences similar to unemployment in terms of the income size which is the basis of personal income tax per taxpayer.
    The income level in the North Great Plain region is lower than the country average mainly in terms of income paid for work, where this difference is 23%, while it is only 5% in the case of social income. Altogether, the income and expenditure data of the North Great Plain region are not favourable.

  • Management of phytopathogens by application of green nanobiotechnology: Emerging trends and challenges

    Nanotechnology is highly interdisciplinary and important research area in modern science. The use of nanomaterials offer major advantages due to their unique size, shape and significantly improved physical, chemical, biological and antimicrobial properties. Physicochemical and antimicrobial properties of metal nanoparticles have received much attention of researchers. There are different methods i.e. chemical, physical and biological for synthesis of nanoparticles. Chemical and physical methods have some limitations, and therefore, biological methods are needed to develop environment-friendly synthesis of nanoparticles. Moreover, biological method for the production of nanoparticles is simpler than chemical method as biological agents secrete large amount of enzymes, which reduce metals and can be responsible for the synthesis and capping on nanoparticles.

    Biological systems for nanoparticle synthesis include plants, fungi, bacteria, yeasts, and actinomycetes. Many plant species including Opuntia ficus-indica, Azardirachta indica, Lawsonia inermis, Triticum aestivum, Hydrilla verticillata, Citrus medica, Catharanthus roseus, Avena sativa, etc., bacteria, such as Bacillus subtilis, Sulfate-Reducing Bacteria, Pseudomonas stutzeri, Lactobacillus sp., Klebsiella aerogenes, Torulopsis sp., and fungi, like Fusarium spp. Aspergillus spp., Verticillium spp., Saccharomyces cerevisae MKY3, Phoma spp. etc. have been exploited for the synthesis of different nanoparticles. Among all biological systems, fungi have been found to be more efficient system for synthesis of metal nanoparticles as they are easy to grow, produce more biomass and secret many enzymes. We proposed the term myconanotechnology (myco = fungi, nanotechnology = the creation and exploitation of materials in the size range of 1–100 nm). Myconanotechnology is the interface between mycology and nanotechnology, and is an exciting new applied interdisciplinary science that may have considerable potential, partly due to the wide range and diversity of fungi.

    Nanotechnology is the promising tool to improve agricultural productivity though delivery of genes and drug molecules to target sites at cellular levels, genetic improvement, and nano-array based gene-technologies for gene expressions in plants and also use of nanoparticles-based gene transfer for breeding of varieties resistant to different pathogens and pests. The nanoparticles like copper (Cu), silver (Ag), titanium (Ti) and chitosan have shown their potential as novel antimicrobials for the management of pathogenic microorganisms affecting agricultural crops. Different experiments confirmed that fungal hyphae and conidial germination of pathogenic fungi are significantly inhibited by copper nanoparticles. The nanotechnologies can be used for the disease detection and also for its management. The progress in development of nano-herbicides, nano-fungicides and nano-pesticides will open up new avenues in the field of management of plant pathogens. The use of different nanoparticles in agriculture will increase productivity of crop. It is the necessity of time to use nanotechnology in agriculture with extensive experimental trials. However, there are challenges particularly the toxicity, which is not a big issue as compared to fungicides and pesticides.

  • Long-term experiments on chernozem soil in the University of Debrecen

    The impact of agrotechnical management practices (nutrient and water supply, crop rotation, crop protection, genotype) on the yields of winter wheat and maize and on the soil water and nutrient cycles was studied in long-term experiments set up in 1983 in Eastern Hungary on chernozem soil. The long-term experiments have shown that nitrogen fertilizer rates exceeding the N-optimum of winter wheat resulted in the accumulation of NO3-N in the soil. Winter wheat varieties can be classified into four groups based on their natural nutrient utilization and their fertilizer response. The fertilizer responses of wheat varieties depended on crop year (6.5–8.9 t ha-1 maximum yields in 2011–2015 years) and the genotypes (in 2012 the difference was ~3 t ha-1 among varieties). The optimum N(+PK) doses varied between 30–150 kg ha-1 in different crop years. In maize production fertilization, irrigation and crop rotation have decision role on the yields. The efficiency of fertilization modified by cropyear (in dry 891–1315 kg ha-1, in average 1927–4042 kg ha-1, in rainy cropyear 2051–4473 kg ha-1 yield surpluses of maize, respectively) and crop rotation (in monoculture 1315–4473 kg ha-1, in biculture 924–2727 kg ha-1 and triculture 891–2291 kg ha-1 yield surpluses of maize, respectively). The optimum fertilization could improve the water use efficiency in maize production.

    Our long-term experiments gave important ecological and agronomic information to guide regional development of sustainable cropping systems.

    This 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.

It’s disadvantageous characteristics can or should be amended, while the advantageous ones should be utilized by considering the principles of sustainability. At the end of this paper, I will make recommendations in connection with the latter point.

  • Causes of floods and flood protection in Subcarpathia

    Subcarpathia is one of the richest regions in surface waters in the Ukraine. Due to its geographical, relief and climatic conditions, it belongs to the active precipitation zone, where great floods frequently occur. As a result of many years of observation, it can be concluded that the interactions of many natural factors can lead to various floods in the catchment area of the river Tisza. These are mostly hydro-meteorological factors, which can lead to great floods with the characteristics of the formed flow. Human activity also significantly influences the occurance of floods: clearing, which can accelerate the process of the runoff, ploughing in the catchment area, which can lead to erosion and the utilisation of areas endangered by floods for various economic sectors.
    A series of questions arose in recent years regarding the formation of floods: what could be the causes of floods and what actions need to be made to prevent them. The evaluation of floods made us conclude that passive protection by using dams does not always ensure protection against floods as these were constructed in different times for different water levels. Many factors can affect the whole process which cannot be foreseen, therefore the development of new solutions and new technologies is necessary in flood protection.

  • Study of plant production modells with different intensity in winter wheat production

    The effects of crop rotation, nutrient supply and plant protection technologies were examined on the yield of Mv PÁLMA winter wheat variety and on the most important diseases of ear and leaf. Our experiments were carried out on chernozem soil in the Hajdúság in 2006 and 2007, and three plant protection technologies (extensive, average, intensive) and three irrigation variations (without irrigation, irrigated with 50 mm, irrigated with
    100 mm) were applied in different crop rotation systems. 
    In the triculture crop rotation a higher rate of infection was observed than in the biculture crop rotation, because the vegetative growth was more expressed after pea and these microclimatic factors were favourable for the development of pathogens.
    In the triculture crop rotation (pea – wheat – maize) the powdery mildew, DTR and leaf rust of wheat were present in both examined years (powdery mildew 5-15%, DTR 14-42%, leaf rust 8-37% in cropyear 2005/2006, powdery mildew 12-32%, DTR 9-29%, leaf rust 8-26% in cropyear 2006/2007). Fusaria could be observed in 2006 (depending on the plant protection technologies and nutrient supply in the biculture 7-27% and in the
    triculture 5-19%). With higher amounts of fertilizers the rate of infection increased and reached its maximum at the highest dose of nutrient supply (N200 +PK).
    We observed the highest rate of infection by ear and leaf diseases in the case of the extensive technology, while this rate could be considerably reduced by the application of the intensive technology.
    Both in 2006 and 2007, yields were the highest at the N100-200+PK levels in the triculture after pea (6028-7939 kg ha-1 in cropyear 2006, 6578-8690 kg ha-1 in cropyear 2007 depending on plant protection technologies), and at the N150-200+PK levels in the biculture after maize (6096-7653 kg ha-1 in cropyear 2006, 4974-8123 kg ha-1 in cropyear 2007 depending on the plant protection technologies). The highest yield maximums were
    reached when pea was the forecrop. The yields on the experimental plots of the intensive plant protection technology was 224-2198 kg ha-1 higher (depending on the forecrop) compared to the plots where the extensive technology was used.
    The highest yield without irrigation was at the N150+PK both in biculture and triculture crop rotation. Among the irrigated variations Ö2 and Ö3 at N200+PK fertilisation resulted in the highest yield in the biculture crop rotation, while the N100+PK level in triculture system. In the biculture crop rotation the extra yield was 14-51% higher (575-1225 kg ha-1 depending on plant protection technology) when 50 mm water was irrigated, and
    15-54% higher (778-2480 kg ha-1) if 100 mm irrigation was applied comparing to the non-irrigated versions. The yield was  7-17% higher (560-1086 kg ha-1) in the Ö2 irrigation variation, and 8-23% (691-1446 kg ha-1) higher in the Ö3 irrigation variation compared to Ö1 irrigation variation (non-irrigated).
    A correlation analysis was made to reveal the connection between the yield, the amount of fertilizers, the rate of infection, the plant protection technologies and the forecrops. Strong positive correlation (0.846) was found between year and fusaria infection. Strong positive correlation was observed between fertilization and powdery mildew infection (0.525), fertilization and DTR (0.528), fertilization and yield quantity (0.683). Lower
    correlation was found between fertilization and leaf rust infection (0.409), and forecrop and yield (0.472), recpectively. Negative correlation was calcutated between plant protection technologies and DTR (-0.611), and plant protection technologies and leaf rust (-0.649).

    In Hungary the renewable energy utilization is planned to achieve 13% by 2020. Biogas production is one of the fields with the largest energy potential. Achieving high efficiency during continuous production despite the mixed and variable composition of input materials is the most common problem which the newly built biogas plants using agricultural raw materials have to deal with. The first experimental reactors at the Department of Water and Environmental Management were built 12 years ago. Control and automation of the four separated bioreactors were executed with ADVANTECH GENIE 3.0 software which granted pre-programmed measurement and points of intervention for pH, temperature, CH4, CO2, H2S, and NH3. The system became out-of-data, therefore in 2010 it has been redesigned and tested. The system is controlled by Compair Proview SCADA (Supervisory Control and Data Acquisition) software running on Linux platforms. The Fusarium infection caused serious yield-losses in cereal production in 2010. In the case of cereal products, which non-utilizable as forage seems an optimal solution is utilizing as biogas raw material. The raw material was based on the Fusarium infected maize. In the recent publication infotechnological and technological experiences of the pilot test period are evaluated as well as direction of future development is defined.

    In 2007, a new sport strategy was implemented, (XXI National Sportstrategy), which analyses the current conditions in recreational sports in Hungary and describes its developmental potentials. Additionally, last year a new concept for university sport was introduced (Hajos Alfred Program), having as its most important goal, to develop the recreational sporting activities within the universities’ environment. The latter is of high importance, as this is the last period, when, on an institutional level, we can establish and enhance the need for physical activity among young generations. In this study recreational sport is analysed in the University of Debrecen Faculty of Applied Economics and Rural Development. The purpose of the study was to analyse data on the sporting habits of the faculty students, their preference of where they like to exercise, within or outside of the university campus, and the reasons which can be found behind these preferences. Moreover, this study aimed to evaluate the service quality offered in university recreational sports. Data collection was completed on a paper based questionnaire, 42 closed-type questions were included and a total of 123 students completed it. Based on the results, college students usually complete their competitive level sport activity when they enter college and they continue this activity on a recreational level. Almost two third of them choose to exercise in places outside of the university campus. For those who choose university facilities for their recreational exercise, they do so because; it is usually cheaper and closer to access. In the service quality results we see, that females are less satisfied with teaching staff quality than males, it may be possible that females need more and more effective implementations in order for the universities to better satisfy their needs for physical activity.
