Managerial aspects of operating performance groups in agriculture
Published February 23, 2008
43-46

Although we often witness groups, teams operating on various fields of life, we have not learnt much about various types of groups and teams in the agricultural sector, little is know about operational rules, internal properties, even less the managerial aspects. The Department of Management of University of Debrecen has been conducting researc...h in this field for many years. In the framework of the research program, I have surveyed the managerial approach to identify main and typical characteristics of performance groups.
During my researches I was determined to find out more about internal rules, relations and characteristics.

Employment trends in the Northern Great Plain’s Region
Published July 18, 2012
109-111

Hungary can be divided into 7 regions, of which I am writing about the Northern Great Plain Region in this article. The Northern Great Plain consists of the counties Hajdú-Bihar, Jász-Nagykun-Szolnok, and Szabolcs-Szatmár-Bereg. There are 389 settlements in the region, which can be considered rather few. The population of the region is nearl...y 1.5 million, which is nearly 15% of the total  population. This region is one of the most disadvantageous regions in Hungary, with its economic indicators ranking the lowest of all regions. Nevertheless, as regarding education and agriculture, the region is considered to be a prominent area.

Usage of Different Spectral Bands in Agricultural Environmental Protection
Published May 4, 2004
123-126

Hyper and multispectral imaging systems are widely used in agricultural and environmental protection. Remote sensing techniques are suitable for evaluating environmental protection hazarsd, as well as for agriculture resource exploration. In our research we compared aerial hyper and multispectral images, as well as multispectral digital camera ...images with the background data from the test site. Hyperspectral records were obtained using a new 80-channeled aerial spectrometer (Digital Airborne Imaging Spectrometer /DAIS 7915/. We have chosen two farms where intensive crop cultivation takes place, as test sites, so soil degradation and spreading of weeds can be intensive as a result of land use and irrigation. We took additional images of air and ground with a TETRACAM ADC wide band multispectral camera, which can sense blue, green and near infrared bands. We had detailed GIS database about the test site. Weed and vegetation map of the area in the spring and the summer was made in 2002. For soil salt content analysis, we gathered detailed data frome an 80x100 m area. When analyzing the images, we evaluated image reliability, and the connection between the bands and the soil type, pH and salt content, and weed mapping. In the case of hyperspectral images, our aim was to choose and analyze the appropriate band combinations. With a TETRACAM ADC camera, we made images at different times, and we calculated canopy, NDVI and SAVI indexes. Using the background data mentioned above, the aim of our study was to develop a spectral library, which can be used to analyze the environmental effects of agricultural land use.

Romania is one of the largest producers of sunflower closely followed by Bulgaria, Hungary, France and Spain. The total sunflower production increased after 1990, due the increase of cultivated surface during the moderate yield average increasing rate. Last year, Romania was ranked first in the European Union (EU) for the area cultivated with s...unflower and the total production of sunflower seeds, according to the National Statistics Institute (INS). Romania's position on the map of sunflower producers area is supported by about 1 million hectares sown. In the segment of sunflower productivity, Romania has an unfavourable position, situated in the last places in the classification of the EU's most productive agricultures. In order to increase production per hectare, it is required to perform measures aimed at the elements of sustainable cultivation technology, including the stability of the production level by ensuring phytosanitary protection.

The Natural, Social and Economic Conditions and Opportunities for Development of Balmazujvaros, Especially in the Case of the Co-operative Kvaliko
Published May 12, 2002
77-85

Balmazujvaros as a settlement near Hortobagy has to cope with both advantages and disadvantages. Its natural and social conditions are mainly given, the agricultural characteristic is dominant, and the number of the employed is the highest in the agricultural firms and processing industry. Developing the third sector, including hosting, tourism..., eco-tourism, thermal-tourism, may be an opportunity for the city. The subsidy for rural development relating to the SAPARD-programme may contribute to this, as the city is the member of the Association of Hajdu Towns.
The agriculture plays an important part in Balmazujvaros in which production and marketing of vegetables and fruits excel. Several farmers realised this opportunity and founded the Marketing Co-operative of Vegetable Producers in Eastern Hungary, that is the Kvaliko. This PO works in a Corporation form and is constantly developing, spreading and expanding its choice making use of the local natural, social and economic conditions and applications for realising its investments. This PO may set an example for the other entrepreneurs and farmers of Balmazujvaros to co-operate and it may be considered as an already realised opportunity.

Energy Use of Biomass
Published December 6, 2005
264-272

In this study, energy utilization of biomass is introduced with a short description of renewable energy sources and utilization possibilities of biomass.
Presently, the necessity of renewable energy sources is increasingly obvious. Among renewables, energy from biomass is to be highlighted, since this allows versatile, cheap utilization of t...he sun’s energy. In this respect, Hungary has advantages. Direct heat utilization and biogas production are available procedures today, whereas biodiesel and bioethanol are expected to spread in the near future. Biogas production is possibly the most versatile method for biomass conversion: it can produce energy from materials inapplicable for other utilization; at the same time, it is capable of neutralizing harmful wastes; in the end, it produces also valuable fermentative products, from bio-manure useful in agriculture, to pharmaceutical raw materials.

The examination of the agronomy, the amount of yield, and the yield stability of winter wheat varieties
Published December 21, 2008
61-72

Our research was carried out at University of Debrecen Centre for Agricultural Sciences Faculty of Agriculture Institution of Plant Sciences Látókép Research Institute through the breeding year of 2003/2004, 2004/2005 and 2005/2006 using cherrnozem soil. In our research we tested 14 chosen autumn wheat varieties during the three crop years.<...br>The different varieties showed very dissimilar ability of resistance against diseases through the three crop years. We could observe both susceptible and resistant varieties. Susceptible varieties got diseases even in favourable crop years. The observed winter wheat varieties showed higher susceptibility against helminthosporium (21.8%) and leaf rost (16.4%). Among the 14 varieties we experienced the least susceptibility in the case of ‘Gaspard’ and ‘GK Kalász’. The research showed that the disease of fusarium undoubtedly depends on the features of the crop year.
In terms of stem solidity we experienced big differences. Among all the observed winter wheat varieties the mid-late ripening ‘Gaspard’ showed the best results in the average of the three years, only 5.3% was beaten down.
The three ripening group of the winter wheat showed the following average yield in the average of three years: 7065 kg/hectare (early ripening varieties), 7261 kg/hectare (late ripening varieties), 6793 kg/hectare (mid-late ripening varieties). Among all the observed varieties the early ripening ‘Flori 2’ produced the biggest yield (7692 kg/hectare).
During the three crop years we reached very different amounts of yield which means that weather conditions had a telling affect on yield. In 2004 we reached an excellent average yield in all the tree  breeding groups because of the favourable weather conditions. In 2005 we had a moderate amount of yield because of the unfavourable weather conditions of winter. The year of 2006 showed the smallest amount of yield which is due to the fact that the plant grew less thick than usually.
There were significant differences among the observed varieties in the term of yield, which can be attributed to dissimilar biological basics.
One of he most important questions is the yield stability of the varieties. We had extremely different results at this field. Speaking in general terms we can state that both weather conditions and genetical abilities have a determining effect on yield. In the case of winter wheat varieties the rate of yield fluctuation was quite big, moving in the interval of 33.7-70.3%. Among all the observed varieties ‘Gaspard’ showed the best yield stability (33.3%).

69-72

In Hungary 6.2 billion hectares are used for agricultural and from this area 5.0 billion are polluted by ragweed. In addition, the export of agricultural products will be threatened because of their pollution. Ragweed results also problems in human medicine because of its pollen allergy. More than 30% of the habitants are affected directly or i...ndirect by allergyc diseases. On an annual basis nearly 60 billion HUF is spent on defense against ragweed. From this budget 30 billion HUF comes from the damage of the agriculture and other 30 billion for the cost of the therapy and health insurance. To solve the problems caused by ragweed needs new ideas. The proposals are the gathering and comprehensive utilization. A leap forward, from the ragweed new, market–orientated product should be developed.

Anti-Oxidants in Agriculture
Published May 4, 2004
195-200

Today’s programmes aiming at enhancement of fruit and vegetable consumption have been intensified. In the unanimous view of experts, different health problems, such as those of the immune system, inflammations, and even certain cancerous diseases can be prevented and/or cured with regular consumption of fresh (raw) fruit and vegetables. It is... well-known fact that among the biologically valuable components, antioxidant compounds – C- and E vitamins, as well as carotinoides – play an important role. In this field, Hungary can expect success in the future since it has excellent plant genetic stock. Regretfully, national data banks regarding cultivation technology, cultivation areas or varieties for fruits and vegetables and their antioxidant contents do not exist in Hungary. Nevertheless, in connection with the so-called “Hungaricums” its existence would be of urgent necessity. Such excellent Hungarian products are – among others – a lot of sour cherry varietiles, the Szeged green pepper and the Makó onion. They enjoy high priority as “Hungaricums” even in the European Union and such activities that support these kinds of products should be enhanced by intense and consequent research work, which may prove their role as functional foods. Presently’ the USA leads in the research of antioxidant compounds of sour cherry, and so far 17 of these compounds have been found partly in Hungarian varieties. Similar research on green, and ‘pritamin’ peppers have not gone so far since they were limited only for seasoning paprika. In Hungary, studies on onion and garlic have not been performed. It should be mentioned that due to the continental climate, these products may be cultivated, consumed or processed only in a limited period. Taking this into consideration, processing and conserving methods are needed which make the consumption of these fruit and vegetables as functional food possible year-round. Scientific establishment of this set of questions is of current concern, because consumption of these products could have an important role in improving the health status of the Hungarian population in the future.

The Common Agriculture Policy (CAP) took shape in the early 1960s. At that time the first action was to stop food shortages. Among the objectives of the Treaties of Rome appeared the subvention of rural development had not yet.
Rural development appeared, in 1992, in connection with accompanying measures, and by end of decade, the European A...gricultural Model had taken shape. Agenda 2000 pointed out the direction of rural development and introduced the first and second pillars in the CAP. The regulations of rural development were simplified by 1257/1999/EC, which stressed the importance of rural development to and it has to continue the principle of subsidiarity and has to be decentralized.
The last enlargement raised new problems, the mid-term review of Agenda 2000 occurred and resulted in a new CAP-reform in 2003. The 1783/2003/EC rural development regulation modified the previous regulation. According to the new regulation it is necessary to strengthen the new rural development policy, enlarge the circles of accompanying measures, place greater emphasis on requirements of environment, human resource, animal welfare and plant health. Digression and modulation take part in the new CAP-reform in order to increase the role of rural development in the common budget.
In the next budget from 2007-2013, the European Union wants to create a single rural development fund and simplify programming, financing, monitoring. The EU wants to enlarge the instruments of rural development with a four axis model.

Stand evaluation, crop estimation and yield analysis of winter wheat for the optimization of yields
Published May 23, 2019
103-109

The authors have been carrying out stand evaluation, crop estimation and yield analysis in winter wheat since 2012. The sampling areas were assigned at the fields of the Training Farm of the Faculty of Agricultural and Food Sciences of Széchenyi István University Mosonmagyaróvár according to the structure of the cropping system. According t...o their observations the value of field emergence is always lower than the laboratory germination. The weak emergence is important because the lower plant density cannot be compensated by the increased tillering in spite of having larger plant growth space. It is proven by the fact that they detected strong productive tillering even at 5 and 10 mm plant spacing while there were single-spiked plants at 40-50 mm plant spacing as well. The analysis revealed that the total ear mass and grain mass of wheat plants bearing two or more ears is almost the double than that of the single-spiked plants. It was a further basic experience that the largest ear of ”multiple-spiked” plants is always heavier than the single ear of one-spiked plants. Plants with intense tillering and more ears demonstrate the importance of proper seedbed preparation and drilling and the significance of sowing good quality seeds. These are the factors that determine field germination and emergence, influence the speed and intensity of initial development and by all these factors the sufficient productive tillering. The authors emphasize the use of exact and objective methods at crop estimation, e.g. the relationship between the ear mass and the yield which is in strong correlation whilst ear length and grain mass are not suitable for a precise estimation. The authors conclude that crop estimation and yield analysis must be inevitable tools of modern crop production and will be particularly important in precision agriculture. These tools also qualify the job done by farmers and helps to identify the areas that require special attention.

Consumption of fertilizers in districts of Slovakia in the period 2006–2015
Published September 5, 2018
389-398

Consumption of fertilizers in districts of Slovakia in the period 2006–2015 Water quality in the surface streams is influenced by several factors. One of important information which can help us to solve problems with quality of water in water body is a distribution of point and non-point pollution sources in a river basin and also amount of p...ollutants released from them to surface streams. An example of a point source of pollution is the outlet from wastewater treatment plants (industry, urban areas, farms, etc.). On the other hand the most significant non-point source of pollution is considered the application of fertilizers in agriculture.

In this paper we have evaluated consumption of organic and industrial fertilizers in Slovakia in the period 2006–2015. Total (in tonnes) and average (in kg ha-1) consumption of industrial and organic fertilizers was analyzed. In monitored period, the amount of applied organic fertilizers was much higher than the amount of applied industrial fertilizers and in addition a significant part of total fertilizers consumption had nitrogenous fertilizers in a group of industrial fertilizers. In a group of industrial fertilizers during the period 2006–2015 we observed just moderately increasing in their consumption, while in the period 2010–2015 the average amount of applied industrial fertilizers per hectare of agricultural land increased by about 20 kg ha-1. On the other hand, in a group of organic fertilizers we observed a decreasing in consumption of fertilizers.

Case study based analyses of economic viability of Hungarian beef farms
Published July 16, 2007
184-193

Our country has great traditions in the field of beef production. As early as the Middle Ages, Hungary was known as Europe’s beef exporter. In this decade, production of the Hungarian Grey has increased, due to the popular method of keeping these animals extensively. These animals were even exported to the European markets on foot.
After j...oining the European Union, this sector of agriculture has been receiving attention due to the major subsidies which were given. Accordingly, numerous farmers have tried to enter this sector of production. However, the power relations have been changed lately, as have the technology used in production, which has undergone several developments. The integrative connections in the sector had been split and also the size of optimal and sustainable production has arisen.
The economic activities must be judged by their effectiveness and profitability, but in most cases their effectiveness can only be seen through such outstanding facts which are independent from the farmer.
I would like to model the economy of a certain enterprise, and the size and the level of its production, through my research under the actual economic circumstances. In my research, I pay special attention to the circumstances which are important in the Hungarian agricultural sector and rural development.

Optimized balance between crop productivity, restoration and maintenance of vital soil functions and soil carbon sequestration and storage – the SmartSOIL (FP7) project
Published November 13, 2012
213-215

Soils provide the most indispensable function of supporting the production of food and feed for a growing human population. At the same time they provide a range of regulating and supporting functions related to climate change and removal of greenhouse gases. The majority of the soil functions are closely linked to the flows and stocks of soil ...organic carbon (SOC); low levels of both flows and stocks may seriously interfere with several of the essential soil functions and thus affect the ecosystem services that soils deliver. Soil degradation is considered a serious problem in Europe and a large part of the degradation is caused by intensive cultivation practices in agriculture. The aim of the SmartSOIL project is to link the results of different scientific fields through a holistic and multidisciplinary approach and as a result develop a decision making tool contributing to sustainable development.

The impact of employment and income circumstances on the development of regions
Published July 24, 2014
15-19

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.

Comparison of Reproductive Performance of the Roe Deer (Capreolus capreolus, L.) Among Different Regions
Published October 11, 2006
41-46

The potential and actual number of offspring of roe deer and the difference between these figures (prenatal and postnatal loss) significantly vary in each population yearly. The objective of this study is to examine the potential and actual number of offspring, the number of losses, and to find a link between the most important biological chara...cteristics of does (body weight – BW, condition – KFI) and the number of raised offspring on four territories on the Great Hungarian Plain.
Where the number of corpora lutea (CL) is the highest, there the losses are the highest as well, and the number of raised offspring is the lowest (region I.). Here, the rearing loss is double that of the weakest territory (region IV.). Rearing losses can be associated with the fenotype of does (BW, KFI) but environmental factors also have determinative importance. Where the number of twin-calving does was the highest, I found four times more does without a fawn than where the number of twin-calving does was the lowest. The nursing success was the best (the losses were lowest) in the region where the potential offspring (number of CL) was also the lowest, but the coverage of the habitat and the proportion of forests were largest. The food supply for the animals in autumn and winter are not enough, the structure of the habitat has to be improved as well, so that it might become adequate for game protection in extreme weather conditions.
The results have to be considered as preliminary ones. It is essential to continue and extend the research to increase the reliability of the results.

The greatest part of the incomes (nearly fifty percent) of the European Union is spend on the agriculture and the agricultural policy is the most complex field among the common policies. In Hungary the payments from Guarantee Section of EAGGF are carried out by one Paying Agency (Agricultural and Rural Development Agency), the post audit of pay...ments are carried out by Investigation Network of Hungarian Customs and Finance Guard on the base of Council Regulation No. 4045/89. A full co-operation of the business operators is expected during the audit, which means the presentation of the complete accounting file related to subsidies. To avoid declarations on irregularities during the audit and the following order on repayment of the subsidy, all requirements of gaining subsidies have to be kept. The state authorities, in present case the customs authority should pay special attention to the risk analysis activity, and its harmonising with the proposals and guidelines of the Commission. Getting acquainted and using in practice the actual requirements and proposals of the Commission’s guidelines is expected at all levels of the control service of the HCFG, but primarily the Special Service has to continue its present practice in this field. The measures mentioned above, respectively the effective period taken under analysis teens from the date of accession until June 2005.

Remembrance to László Huzián (1923-1996)
Published November 10, 2010
5-11

László Huzián was a determining personality of the higher education of Hungarian crop protection more precisely that of the agricultural entomology. Training of the scientific and extension specialists of Hungarian agricultural entomology from 1960 till 1983 would have been unimaginable without him. He was the builder of the agricultural ent...omology school established by Gusztáv Adolf Manninger, the developer of the training’s essential and organisational standard, who sacrificed his life’s work for developing the crop protection. He found, characterized many pests (E.g. Scrobipalpa ocellatella, Lixus scabricollis, Tanymecus palliatus, Mesagroicus obscurus) new for the Hungarian fauna and worked out a control technology against them. It is important to mention his activity in creating the forecasting of the big field crop animal pests mainly that of the sugar beet pests. One top of his educational work was the wonderful manual „Agricultural Entomology” written with Sándor Bognár in 1979. László Szalay-Marzsó said of this book that it was impossible to write a better one. He has been right. The magnificent crop protection library and the unique richness and accuracy of the animal demonstration material (slides, pictures, preparates, showcases, etc.) established at the Gödöllő University of Agriculture can be thanked to his extraordinary systematizing mentality and tireless efforts.

Nowadays global warming is a major issue to our environment. This issue is generated by the modern human activities like industry and intensive agriculture. This research is about methane emission from rice paddy fields. The aim of the study is to lower the methane emission from the field with the help of using different type of fertilizers, wh...ilst we keep in focus the efficient economic operation. The main experimental field is Matsuo paddy field, (Matsuo town, Sanbu city, Chiba prefecture) which is analyzed by the Chiba University’s soil science laboratory, they provided the data for this study. During the study three type of fertilizer was analyzed which are all organic and the control was a regular chemical fertilizer. For all fertilizers the cost and income of the production were calculated and the profit was weighted with the methane emission what a specific fertilizer produced during the cultivation. In the future if the organic fertilizers are in focus than it is necessary to find a new material what can be competitive with the chemical fertilizers in focus of GHG emission or find an alternative way of the usage of methane in biogas production.

Application of GIS, precision agriculture and unplugging cultivation in plant breeding of Karcag
Published December 15, 2019
49-56

In the last two decades, the prevailing ecological conditions and climate change have caused negative effects. Therefore, a paradigm shift is needed in the field growing of plants. The latest inventions, digital technologies, precision cultivation are not enough, the mentality of the farmers is more important. For this reason, not only big fina...ncial sacrifices, but adequate receptivity are needed on behalf of farmers. Adequate skills and continuous self-education are necessary. The yield of plant growing farms is determined by ecological conditions to a 40% extent, genetic background of the seed has a 30% share and the applied agricultural technology has a proportion of 30%. In different agroecological conditions, bred varieties of plants have bigger tolerance to unfavorable factors of the regions and significant yield stability. Farmers, who buy and sow seeds, can only contribute to the genetic potential of the seeds with cultivation technology. Plant breeding provides stable genetic background and good quality seeds. Breeding activity – choosing variety proposants, breeding them, selection work, classical breeding process for 8-10 years – must create new landraces, which can produce balance, high yield and have good quality parameters in extreme ecological conditions, yearly excursion and have higher tolerance to unfavorable factors of the region giving significant production stability for farmers. In Karcag GIS technology, precision cultivation elements and soil-friendly agrotechnical methods have been introduced which largely support the aims of breeding and can also provide optimal cultivation conditions in extreme years. Because of the specificity of breeding the main aim is not only to increase yield but to provide harmonic growing for bred materials, to decrease the number and the cost of cultivation and to be punctual. In this study, applied new methods and technologies are introduced.

Effects of Site on Winter Wheat Quality 2002/2003
Published October 3, 2019
100-107

The demand of modern societies for high food quality is evident. Thus, it is important for agriculture to produce row materials that are valuable for nutrition and have favourable characteristics for food processing. For this we need a knowledge about the factors which determine the quality of products. One of the main features of plant product...ion is the “immobility”. This way the characteristics of the field influence the quality of the product, like example winter wheat, which is the main cereal in Hungary and Europe.
The Concordia Co. has charged the Central Laboratory of Debrecen University, Agricultural Centre with laboratory testing of the 2002/2003 winter wheat crop. The samples consist of thirteen winter wheat varieties from six different sites under the same cultivating conditions. Therefore, the important wheat quality factors were analysed solely against site conditions with the use of Győri’s “Z” index, which contains these parameters.
Soils were tested first. In this experiment excepting the negligible differences between the sites, there were no linear relations found between quality factors, productivity and soil features. The case is the same with the relation between precipitation, temperature and quality parameters. However, it must be noted that additional soil analyses are required to interpret the extreme results obtained from Karcag.
The calculated Győri’s Z-index shows relative stability concerning certain varieties, although considerable deviation can be found in varieties related to the sites. According to these results, it can bestated that winter wheat quality was not linearly influenced by soil and weather in the 2002/2003 vegetation period. As the same cultivation technology was used in the experiment, the index was determined by genetic features. It must be noted that these findings are relevant only to this experiment.
