Evaluation of mineral element content of beetroot during the different stages of the growing season
459-469Views:470In modern nutrition, bioactive materials of different vegetables are especially important to be researched. The experiment was carried out on March 30, 2016 (sowing date). Mineral element content (B, Ca, Cu, Fe, K, Mg, Na, P, S, Zn) was evaluated on the 60th, 85th and the 105th day of the vegetation period. The data are presented as the mean of five varieties which can give the real state of these parameters of beetroot grown on lowland chernozem soil.
In the young beetroot leaves (60 days) the mineral element content was higher than in the older ones (85 days). The calcium and magnesium content of the leaves was much more favourable (10 times higher) than in the root. The potassium content of leaves has reached the amount of 5000 mg kg-1, but at the same time more than 3000 mg kg-1 was detected in the improved root. This value is favourable for the potassium supply of the human organism.
The sulphur content (1300 mg kg-1) of the leaves was the highest on the 85th day of vegetation period. Similar tendency was detected for boron content (2.45 mg kg-1), while for iron content it was higher (28.23 mg kg-1) in the younger leaves (60 days).
Finally, it can be concluded that the increased element content of beetroot leaves will be a favourable source of mineral element supply of the human organism.

Biological control of sweet chestnut on Pécsbánya, Hungary
77-81Views:391The supervision of plant hygiene of sweet chestnut grove on Pécsbánya (South Hungary) started more than four years ago. Hypovirulent strains were applied as a biological process to control Cryphonectria parasitica fungus which causes the chestnut blight disease. By now the performed interventions have shown obvious results, the vitality of the trees has greatly improved, the amount of harvested nuts is increasing, and the hypovirulent strain has been spreading within the area. During plant health inspection the galls of chestnut gall wasp (Dryocosmus kuriphilus) was found in the year of 2015, which is the obvious symptom of new occurrence of the pest. The pest was eradicated by destroy galls, which allows taking out of consideration the damage by now in this area.

An unimportant insect pest with characteristic symptoms: Halticus apterus (Miridae)
19-23Views:324Halticus apterus, a tiny mirid bug with jumping hind legs has not been taught in agricultural entomology courses in Hungary. However, the most detailed agricultural entomology text book, the “Handbook of Agricultural Entomology” briefly presents the pest. Although, it is common in Hungary, its damage is insignificant because of the low density; it can cause quality loss in feed crops only. Nevertheless, its special symptom – spottedness – is worth taking into consideration. The author has been studying pests and natural enemies of alfalfa for a long time (at least ten years), so he focused attention on this species. Occurrence of H. apterus was only sporadic in the alfalfa field, but it showed characteristic and frequent symptoms at a density of averagely three individuals per alfalfa plants in mixed plant associations at the studied field edge. By presenting the damage appearance and form, it was possible to make a more accurate description of H. apterus’symptoms, and with evaluating relevant European references, also the detailed entomological characterisation, economic importance and assessment of future risks have been achieved. As a difference to former descriptions, the special leaf spottedness of H. apterus does not consist of homogenous round spots but rather of spherical conglomerations of tiny whitish dots caused by the piercing and sucking mouthparts and the injected saliva

Fight Against Hunger: A Worldwide Challenge at the Onset of the Third Millenary
3-11Views:135We live in such an era and face such a century, in which the growth of the- world population, the problems deriving from the population explosion will create an unprecedented and never recurring situation for Hungary and the Hungarian animal husbandry as regards the tasks and possibilities ahead us. While presently 6 billion people live on Earth, in the first century of the third millenary the population can reach 10-12 billion and is expected to stagnate around that number.
The Third World, the so-called developing countries struggling with enormous difficulties, makes up for 90% of the annual population growth of 80-90 million people, while the population of the developed countries is stagnant or decreasing. In this aspect, Hungary' s situation is extremely worrisome, because our population has been decreasing for two decades, and according to recent demographic forecasts could drop to 8 million in the next century if the present trend continues. This should be impeded, among others with the contribution of animal husbandry.

Comparative Senses-based Investigation of Traditional and Modern Apple Cultivars
70-74Views:130Apple consumption has significantly decreased over the last 10-15 years in Hungary. While consumption of fresh apple was 25 kg/person/year before the change of regime, today it hardly exceeds 10 kg according to careful estimations. In spite of the fact that the former dull cultivar structure (Jonathan, Starking, Golden Delicious) has widened with numerous new cultivars, apple consumption in Hungary has not increased. Unfortunately, customers do not or scarcely know most of these new cultivars.
In a survey conducted among the students of five Hungarian universities, we gathered information about comsumer opinion of both and older cultivars.
Numerous questonnaires – 592 – were filled out on 8 cultivars (Jonagold, Novajo, Topaz, Golden Reinders, Idared, Pinova, Braeburn, Jonathan, Starking) about the qualitiy parameters that determine the value for consumption. The results clearly show that besides the old cultivars, such cultivars are preferred that are known worldwide, such as Jonagold, or Golden (free of russetting) or the resistant Topaz.
Promotion of these cultivars and creating the possibility of their supply can help to increase a fresh apple consumption. -

73-76Views:191Under the GENOMNANOTECH Debrecen Regionális Egyetemi Tudásközpont (GND RET) research program in summer 2007 in UD Centre for Agricultural Sciences and Engineering Faculty of Agricultural Science Institute of Horticulture experiments were launched to transform tobacco plant by plastid transformation technics.
Our aim was to adopt first in Hungary the tobacco plastid transformation technics, which were used in Waksman Istitute Rutgers, The state University of New Jersey (USA) leading with Prof Dr. Pál Maliga. Scientists won scholarships learn and use this technics in the University of Debrecen. -
Labour market characteristics of Ukrainian employees with special regard to the North Great Plain region
67-72Views:195National Employment Public Foundation founded our research to examine the employment characteristics and job market importance of Ukrainian citizens in Hungary in 2008. As the means of our investigation we analysed available statistical data and conducted a survey. Ukrainian citizens working in Hungary with valid work permit were questioned. 226 people were in the sample.
Hungarian job market processes were not significantly affected by the officially employed Ukrainian citizens because their number was rather small in relation to the number of registered unemployed people and in relation to the available job positions. It can be stated that Ukrainian citizens mainly work in positions where high specialised knowledge is not a requirement.

The situation of the Hungarian apricot farming and its developmental tendencies
163-170Views:206The EC has declared „gönci magyar kajszi” as a product of specific origin with geographicald enomination. The „pálinka”isregistered Hungarian productin the EU. The micro-region of apricot production, named Gönc, has the privilege to utilize the great potential for rural development by its apricot production. To determine the development potential connected to apricot, needs through investigations on apricot production.This paper investigate apricot production at global, European and national levels. At national level each key aspects of apricot production have been analized. The final conclusions referring to Gönc micro-regionare: Northern Hungary region has got the biggest apricot area(within that Gönc has got outstanding role). The share of apricot cultivars of gönci origin ”has got overwhelming role in the Hungarian Cultivar assortment, the living tradition of production in this micro-region makes it possible, that gönci apricot will contribute to the overall socio-economic development in the region to a remarkable extend.

Connections between land usage, property structure and agricultural enterprises in Hungary
31-34Views:158The last decade of Hungarian agriculture was marked and changes which affected all parts of agricultural production. This process resulted in a new ownership and organisation structure. The paper presents the effects of the changes in ownership on land use and the various enterprise forms and intends to outline the main tendencies. In general, it can be stated that the role of agriculture in GDP production and employment is decreasing in Hungary, but according to concurrent opinions of experts, agriculture still has and will have a major role in income production and the ease of social tensions in rural areas in the future as well. Hungary’s accession to the European Union provides new chances and new prospects for Hungarian agriculture and rural areas. Hungarian agriculture became a part of the internal market which includes about 450 million people. The safety of marketing became stronger, the rate of financial support is increasing and the income of growers will increase in the future. This process implies more obligations and the keeping of strict regulations. Competition inside the internal market is intensifying, competitiveness will be more important while the chances of development and investment of the growers and the feasibility of more effective land use are increasing. After the accession, integration into the directives formulated in the CAP and the packages of measures accepted in it is framework have growing importance.
These directives encourage farm-reallocation, namely the rational estate concentration. In general, it can be stated that rational estate concentration, and more effective land use as a consequence, will increase the efficiency of agricultural production. -
The institutional background of local sustainability strategies
7-13Views:148The system of local sustainability strategies is shaped by the intentions of the central government and local initiatives together. From the aspect of the hierarchy of government organization in Hungary it means that there are institutions on the central government’s side – different ministries or other governmental institutions – the role of which is mainly coordination; and local governments (regional and local as well) also form their institutions at the municipality.
It is important to examine the institutional background, as in Hungary the formation of sustainability policy is still in its infancy, so it is well worth taking the institutional background of countries the circumstances of which are similar to ours and have successful sustainability policies as a basis. In this presentation I will examine whether the top-down or the bottom-up approach is chosen, which institution is in charge of the process, what the legal background is like, and what sources are available for use in these countries. -
Development alternatives of rural economy
187-191Views:159Environmental, natural, social and economic processes undergoing both in Europe and in the world predict such a 21st century that is characterised by increasing resource-crisis from both economic and ecological aspects. Therefore, it is very important for Hungary to see what happens to its natural resources, epecially to its agricultural land, water reserves as well as the biodiversity of the local unique flora and fauna. One of the most significant issues of the rural areas of Hungary is whether we can preserve the natural habitats and the various biodiversity of the related species, the favourable biological background of agriculture. In addition, whether we are able to provide high quality food for the country as well as for the broader reagion, whether we are able to produce energy from the resources available as well as to provide sufficient opportunities for the population to live and work. These can be considered as the most significant issuesof the coming decades which determine the strategy of the Hungarian rural economies in long term.

Greenhouse gas emissions and Europe 2020 strategy
241-244Views:170Common Agricultural Policy has identified three priority areas for action to protect and enhance rural heritage: (i) the preservation and development of natural farming and traditional agricultural landscapes; (ii) water management and sustainable use and (iii) dealing with climate change. Measures of Rural Development Plan in EU countries promote the development of agricultural practices for preserving the environment and safeguarding the countryside. This is achieved by targeting rural development and promoting environmental friendly, sustainable practices, like agri-environment schemes. Farmers are encouraged to continue playing a positive role in the maintenance of the countryside and the environment. Changes in total emission between 1990
and 2007 do not show any correlation with the total GHG emission. GHG emission was reduced in Hungary, Slovakia, Lithuania, Czech Republic, Romania, Poland, Estonia and Bulgaria, where GHG efficiency is low. -
Possibilities for Growing Fennel in Hungary
119-121Views:143Fennel appers to be cupable of enlarging our vegetable sortiments in Hungary. Ecological conditions favour production. For cultivation, 12,5 plants/m2 are recommended. Fennel requires 250-300 mm water over a 110 day growing period. No considerable pests have been found yet. 1-3 kg/m2 tubers can be harvested. Marketable tubers weigh 200-300 g. Smaller tubers can be dried, pickled or deep frozen.

Current Conditions and Opportunities of Biofarming in Hungary
150-156Views:201The aim of organic farming is not to maximize income, but to achieve optimal product quality. It is completed by the tightest possible material, and energy flow within the farm. Organic agriculture significantly reduces external inputs by avoiding the use of chemo-synthetic fertilizers, pesticides and pharmaceuticals. Instead it works with nature to increase both agricultural yields and disease resistance. Total independence of external resources can not be achieved in Hungary due to the small-scale of organic animal husbandry. Some materials in limited quantities can be purchased from external resources, though the group of these materials is strictly regulated. Organic farming harmonizes with the concept of European multifunctional agriculture, because besides farming, it includes social considerations, as it helps to maintain natural resources and the relationship between people and their environment, and provides a living for those living in the region.
As regards organic farming the fertility of the soil and the health of vegetation can be influenced in various ways. Farmers have to be highly skilled and able to manage a farm with great expertise. Generally it can be stated that as the use of non-organically produced products is limited, the opportunities to correct failures made by the farmer are minimal, contrary to conventional farming. Farmers must be intent on developing the tightest material- and energy flow. This means that organic farms ideally have both animal husbandry and crop production. This energy and skill demanding system of farming is compensated by state subsidies, growing market share and relatively high prices for organic products. -
The examination of alveographical parameters of winter wheat varieties
87-91Views:312Nowadays, many methods have been worked up in the interests of objective expression of winter wheat rheological quality. These define wide spectrum in view of their complexity and apparatus claim. The needs for the methods are definitely increasing in Hungary, too. It is very important to get acquainted with the alveographical quality and qualification and also their using in wide range.
In our research we examined the alveographical parameters of 12 winter wheat varieties in Szeged (in Hungary) on the basis of the results in three years (2005-2007).
We established with correlation analysis that there is no statistical relation between the alveaographical W and G values. The other alveographical parameters have significant correlation. -
A partial botanical survey of a gamepreserve
27-30Views:401Hungary is internationally well known for its high level game management. An important part of game management is indoor game keeping. In Hungary more and more game preserves were founded all over the country. The role of these game preserves to retain forest stands outside of the closed area. According to the law, in the game-preserves the game bearing capacity is not the most important parameter, because in these areas the feeding is continuous. In practice it means that in game-preserves we find a much higher density of games than in nature. This causes a relative big loading of the area (of the herbaceous and arboreal), where the game-preserves are located. Our aim is to study the ecological and management issues of forest- and game resources. The scene of these work is a game-preserve related to the Nyírerdő Corporation (Nyíregyháza).
We have done a botanical survey (plant coverage, life-form spectrum) in the three previous units and in the control area (outside of the game-preserve) as well. Our results show the difference in case of the state of herbaceous plants between areas with higher and lower game density. -
Leaf reflectance characteristics and yield of spring oat varieties as influenced by varietal divergences and nutritional supply
29-34Views:215Inadequacy of nutrients in the soil and sufficient inaccessibility to nutrients is caused by factors that affect production and productivity of spring oat varieties. Exogenous application of nutrient and real time nutrient assessment can therefore reverse these associated negative consequences. A field experiment was conducted to evaluate the response of spring oat varieties to sulphur and silicon based fertilisation. Eight spring oat varieties, four level of nutrient application was arranged in a split-plot design with three replications. The obtained results showed that foliar application of sulphur improves the grain yield of most nutrients responsive varieties by about 34.7%. However, application of silicon had shown a diminishing return association to grain yield of variety GK Kormorán, GK Pillangó, Lota, Panni. LAI, thousands grain weight, SPAD, NDVI was significantly (p < 0.05) influenced by genetic difference of the tested varieties, developmental plasticity, and nutrient application. Significantly higher grain yield was obtained from the variety Mv Pehely than the other tested varieties. Therefore, it could be inferred that a combined use of nutrient responsive spring oat varieties and sulphur containing fertilisers could be important agronomic practice to improve grain yield and to develop climate resilient oat varieties.

Quality management and traceability in crop production
273-277Views:392Today, food safety and quality is an everyday issue. Scandals in the food industry drew attention to the role and responsibility of food producers in the food chain. The European Union has set up a new integrated approach towards food safety, to which Hungary as an EU member and export-oriented country has also joined. The new “from farm to fork” principle states that food and feed production cannot be handled separately, as only feed produced from good quality raw materials can ensure safe food products. Another important issue is the traceability of products, allowing for the localization and recall of the defected item. In Hungary, there have been different documentation systems for tracking and tracing products, such as the land register in crop production, animal register in the livestock sector and hygiene registers in the food industry. In order to meet EU requirements, there is a growing number of initiatives to include primary production in the scope of food safety standards. The study introduces and compares the various management systems used in crop production.

Dilemma of interpreting the Tisza space in regional dimensions
169-171Views:189This study deals with the evaluation of an especially important area, since the Tisza river is the basis of the spatial organisation of the Great Plain, the main spatial structural axis of Eastern Hungary and also its ecologic corridor of continental significance. The Tisza is a river which connects five countries to each other and it has an enormous catchment area. Its longest section can be found in Hungary. Two million people live directly in the spatial environment of the river. The safety and favourable quality of life of these people have to be provided. This is a great challenge from the aspect of regional development, economic, technological improvement, the acceleration of innovation processes, as well as the establishment of natural and environmental harmony.

Labour productivity in the Hungarian agriculture
119-128Views:241This paper presents the situation of the agricultural labour employment and evaluates the agricultural labour productivity in Hungary. Since Hungary’s EU accession, the share of agricultural employment in the total employed population has been stabilized at around 5% in the country. Due to low wages, low profit and low prestige, agricultural jobs are not attractive. The gross and net labour productivity gap between Hungary and the EU have been significant since the EU accession. The agricultural labour productivity of the Hungarian regions also shows a different picture. The labour productivity influences the cost, profitability and competitiveness of products. The advantage of the cheap labour force in Hungary’s agriculture significantly decreased due to low labour productivity. There are several opportunities to increase the agricultural labour productivity such as the increase of labour force qualification, moving toward producing higher value added agri-food products, rejuvenation of population in agriculture and the improvement of the conditions of financing agriculture.

Dynamics of alfalfa production in Hungary: Changes in harvested area, yield, and total production over 30 years (1990 – 2024)
163-169Views:369Alfalfa is a crucial forage crop in Hungary, contributing to sustaining livestock feed and soil fertility management. To assess the dynamics of alfalfa crop production in the country, this study examines the variations and patterns in harvested area, total production, arable land area, and average yield of alfalfa over the previous three decades (1990 to 2024). Our findings reveal fluctuating patterns, with periods of increase and decrease in all parameters under study. While certain years exhibit growth due to favourable climatic conditions and improved agricultural practices, others show declines, potentially influenced by economic factors, changes in crop demand due to a decline in livestock production, and unfavourable climatic conditions, particularly drought. The analysis highlights the complication of alfalfa production trends, underscoring the need for expanding land area and adaptive strategies in Hungarian forage crop management to enhance alfalfa crop production to sustain livestock’s feeding system.

Grassland association stock of plants the examination of the regeneration of a construction
185-191Views:163Due to the drastic change in using the nature like grassland association (one-sided overgrazing – one mowing per a year), by the third year of the experiment in every area, where overgrazing stopped, independently on second sowing and nutrient resupply, Borhidi degradation degree decreased. In the areas where overgrazing with large animal density (sheep) continued, degradation degree was 3.4–5.0 by the third year of the experiment, and Hordeum murinum, which causes animal healthy problems, appeared massively.

Studies on Ostrich (Struthio Camelus) - Review
15-22Views:1902Ostrich has been reared in Hungary for decades, but we have limited information on this species. The aim of this review was to provide a concise description of the ostrich (Struthio camelus) based on international studies. We were to investigate some of the most relevant parameters, such as egg, meat and skin production. In this critical review we managed to sum up the most significant features and productivity parameters of ostrich and effecting factors. So as to make an accurate description of the species we have to know its morphological, behavioural and physiological characteristics. Ostrich is a very special bird with special nutritional and environmental requirements. Ostrich products, regarding egg, meat and skin are considered luxury products not only in Hungary but also abroad. Though egg has a significant nutritional value, it is mainly used for hatching chicks. In Europe we can expect roughly 40–50 eggs from a hen yearly. Ostrich has a lean meat with high protein and low fat and sodium content, moreover it is rich in minerals and polyunsaturated fatty acids. Having these advantageous qualities, ostrich meat should be part of our healthy diet. Skin production is not important in our country, but there is a special demand for high quality ostrich leather globally. In the future our aim is to conduct a research on some of the parameters. As low production rate and embryo mortality is a great deal of problem in ostrich industry, we need to investigate the incubation environment. There is an apparent disagreement among researchers on optimal slaughter age. This is also an area for further investigation. The value of skin and effecting factors on our climate as well as adaptability of the species are also worth for further investigation together with the nutrition what differs from other ostrich breeding countries. Nowadays, there is a great emphasis placed on animal welfare too.

Determination of element contents of commercial and homemade jams
71-75Views:561Various products could be prepared by using fruits as raw materials. In Hungary, the most popular fruit products are spirit, jams, preserves, juices and dried fruits. Jams are made from different fruits, with different fruit content, technology and additives. They can be used for different products or they can be consumed by themselves. These products and their related production processes have great traditions in Hungary. In addition, they are widely used.The aim of our study was to determine the element content of jams and to compare these samples based on their micro- and macroelement content.In this study, 26 fruit jams with different botanical origins were examined. 10 samples were commercial, and 16 samples were homemade products. The determination of micro- and macroelements was carried out by using Inductively Coupled Plasma Mass Spectrometer and Inductively Coupled Plasma Optical Emission Spectrometer. Different element contents were measured [B (249.7), Ca (422.6), Fe (259.9), K (769.8), Mg (280.2), Na (589.5), P (185.9), S (182.0), Al (27), Mn (55), Cu (65), Zn (66), Sr (88), Ba (137)]. Based on element contents, the jams showed statistical differences. -
Examination of the plum psyllid (Cacopsylla pruni Scopoli), a vector of European Stone Fruit Yellows (ESFY) phytoplasma in the countryside of Boldogkőváralja (Hungary)
5-11Views:360European Stone Fruit Yellows(ESFY) phytoplasma disease on apricot was identified by molecular methods for the first time in 1992 in Hungary. Currently, the pathogen is known as’ Ca. Phytoplasma prunorum’. Since, the pathogen become wide-spreaded and manyof the apricot-plantations had to be eliminated. In 2009 and 2010 in the countryside of Boldogkőváralja the infection of the apricot-plantations was about 77%. As the disease spreading and causing large damages, we studied the roleo fpossible vector,the plum psyllid (Cacopsylla pruni Scopoli) in the areas of Boldogkőváralja, North-East-Hungary. Studies were done in the year of 2016, monitoring the behaviour of the psyllids in four different areas, and caught 41 them for further examination. We collected plant samples from those apricot trees, on which the plum psyllids were caught.
