Financial Analysis of Agricultural Enterprises’ Economic Results
270-279Views:38The main objective of this paper is to give an overview about the economic results and financial status of agricultural enterprises in Hajdu-Bihar Count, as well as, froa methodology viewpoint,find the place of the used indexes in the system of effectivity indexes in farm management . From the complex database describing the enterprises, the figures on the balance sheets and profit and loss accounts were used and analysed. As a result of the analysis the below statements can be made:
The owner’s equity ratio within the total equity is very different in corporations and in individual farms. The lower values in case of corporations show their indebtedness. At the same time, the figures indicate that it is more difficult for individual farms to receive loans.
The average of dynamic indebtedness indexes, in case of individuals are closer to 0 which generally derives from the low level of liabilities. The same indexes of corporations o the other hand show significant indebtedness. The figures indicate that the yearly cash flow can hardly cover the net liabilities.
The profitability proportional to the production value is generally low, mostly negative, independent from size and organisational form.
As a summary, it can be said, that individual as well as corporate farms suffer financing problems, the nature of these problems is different in the two groups. On the on hand, the operation and development of the individual, mostly the smaller, farms are hindered by the difficulties of acquiring external capital. On the other hand, the results of corporate, mostly the cooperative, farms is impeded by the burdens of liabilities accumulated in previous years. -
Relationships of Fruit Production and Regional Development in the Northern Great Plain Region
181-187Views:102The role of retaining population in agriculture is stronger and more significant in the long run in the North Great Plain Region compared to other regions. The region has a significant processing industry along with a good basis for producing raw materials, developed food processing capicity and high quality agricultural products typical of the region. The GDP in agriculture, forestry and game management is somewhat higher than the national average.
Variety is of cardinal importance when establishing the quality of horticultural products and determining the product value. The Hungarian breeding results of apple, quince, apricot, cherry, raspberry, red and black currant are promising.
The regulation system of EU the vegetable and fruit market is based on Retail Cooperatives Producers. With the establishment of national vegetable- and fruit production and retail organizations, the market regulation, production and quality development issues of the sector can be handled and solved. Reaching EU standards in fruit production can only be achieved with up-to-date plantation systems and breed selection. A key issue in development is establishing the required financial resources for investments and updating production. In order to reach these standards, significant state subsidies and good credit conditions are needed. By solving these tasks, the sector is expected to become self-financed without government help.
The pursuit of safer production, improving quality and increasing yields require the establishment of up-to-date irrigation systems. The improvement of family farms, motivating land concentration is necessary for increasing average size of plants. Establishing the above mentioned conditions is important since the vegetable-fruit sector is of great significance in the employment of rurally based population, improving their living conditions and executing rural development programs. -
The examination of relation between the C/N ratio and the biogas yields in the Regional Biogas Plant of Nyírbátor
63-68Views:100The Regional Biogas Plant of Nyírbátor was built by the Bátortrade Ltd. The biogas plant contains 6 mezophil and 6 thermophil fermentation tanks, because the biogas production is based on mixed compositions. The regional plant is a multifunctional system. It produces agricultural products and biogas with high methane content. The utilization of biogas is also accomplished here; gas-engines transform it to electricity and
heat-energy. The product electricity is used by the local plants, the surplus is sold.
The aim of the research is the examination of the quality and quantity of the input materials that put into the mixers and follow the seasonal, periodical and optional changes of the input materials. The analyzation of the quality and quantity data can give an answer to the optional changes of biogas production because the input materials determine the composition of the examined recipe. The C/N ratio was between 11-13, the maximal value of the biogas yield was observed by 12.35 C/N ratio. -
The impact of various grape stock cultivars on the As, Cu, Co and Zn content of the grape berry (must, seed)
39-44Views:153Scientific research from the last decades showed that the inappropriate industrial and agricultural production caused an abnormal increase of the potentially toxic elements in the soil. Unfortunately the acidification of the soil is an increasing problem in Hungary. According to Várallyay et al. (2008) 13% of the Hungarian soils are highly acid. Accumulation of toxic elements differs in the genetically diverse plant species. The root of the plant constitutes a filter so that the rootstock is also kind of a filter system, which may prevent that the scion part (such as berry) accumulate high levels of various potentially toxic elements from the soil. The aim of research was to determine how different grape rootstocks influence the As, Co, Cu and Zn content of the musts and seeds. Thus, specifying which of the grape rootstocks takes up the lowest level of these 4 elements (As, Co, Cu and Zn), and accumulates in berries, so could reduce the potentially toxic element load of the grape berries. The grape rootstock collection of the University of Debrecen was set up in 2003 in 3x1 m spacing on immune sandy soil. Grafting of ‘Cserszegi fűszeres’ was started in 2010. We could evaluate yields harvested from 12 rootstock varieties of the experiment in October 2011. We obtained valuable differences in the arsenic, copper, cobalt and zinc concentrations of musts and seeds of ‘Cserszegi fűszeres’ grafted into different rootstocks. The results obtained from the 2011 harvest support the statement that the choice of rootstock might be an important factor to increase food safety. The differences in concentration of the four elements observed in case of the rootstock may have been caused on one hand by the rootstock effect, and on the other hand, the vintage effect has a very significant impact on the vines element uptake. Several years of experimental results will be needed to answer these questions.

Management of phytopathogens by application of green nanobiotechnology: Emerging trends and challenges
15-22Views:275Nanotechnology 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.

Stevia (Stevia rebaudiana B.) yield in the case of different production technologies
71-77Views:197Stevia rebaudiana B. offers a natural alternative of sweetening, potential health promotion plant, and our country shows increased interest about cultivation in Hungary in addition to the neighboring European countries. The agricultural production system installation necessary
understanding of the needs of the plant, as well as exploring the agronomic potential. Field experiments were conducted in 2015 with the aim to highlight some of the technological production parameters and correlations between them. We have reviewed the most important agronomic factors, the spacing (50×50 cm and 33×33 cm), ground covering (agro-cloth covered and uncovered/ control), their vegetative growth (first-,second-order branch), herb yield and quality in effect.
Based on empirical evidence, that the Hungarian climates also have the opportunity of 3 cuttings during a growing season, besides of early planting, optimal climatic conditions (in October didn’t reduce the daily minimum temperature below 0 °C, after cuttings the maximum interval values remain below 40 °C), and adequate water supply and crop protection facility. The 33×33 cm spacing evaporates more than 50×50 cm spacing, because of the dense population, the continuous canopy less able to breathe, so there are serious chances to the pathogen colonization.
Based on the results of our research to the wider 50×50 cm spacing favorable appreciate the stevia optimal progress in terms of qualitative and quantitative parameters of the yield. The stevia yields produced in the Northern Great Plains field cultivation can produce similar results as stevia crop yields in warmer climates, where the primary crops. Our research experience suggest that there is a viable domestic stevia cultivation, developing the necessary technology is still growing further investigation justifies. -
Description of the Micro-Loan Program, payment and conclusions
81-86Views:71The system of microcapital goes back 8 years in Hungary. Its strategy and practice developed at a time when really small enterprises emerged with little practise and even less capital. Specialists organising and executing programs started with microcapital with little experience. This programme provided the young and experienced an opportunity to gain experience they lacked, and seems to have been extremely successful.

Current Conditions and Opportunities of Biofarming in Hungary
150-156Views:88The 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. -
Antioxidant density of Hungarian kapia and red bell pepper varieties
80-84Views:138There is a lot of evidence that the pepper is one of the most important sources of vitamin C. Albert Szent-Györgyi was the first to extract ascorbic acid from a red bell pepper in the 1930s. Previously people had eaten vitamin C on the long voyage to protect against scurvy. Vitamin C is an important antioxidant, and it is a cell protector today. Vitamin C protects the cardiovascular system against infection. This vitamin decrease blood-pressure, a raises the HDL cholesterol level (good), and inhibits gout.
„Antioxidant density” is a biological value indicator obtained in synthetic way. „Antioxidant density” indicates the antioxidant capacity of a particular food, e. g. fruits and vegetables, related to 1 Calorie. In our study, we measured the total antioxidant capacity, vitamin C content and „antioxidant density” of Hungarian paprika varieties. -
Experiences of organizing the social institutions into non-profit companies in Hajdú-Bihar county
99-102Views:88The study attempts to find solutions for relieving the major serious economic and social problems which are resulted partly by the economic crisis, mainly by demographic processes ( decrease of population, declining economic activity, ageing) and which occur all over Europe. In 2007, in Hungary, the Local Government of Hajdú-Bihar county started to reform the social institutions sytems in a unique way in the interest of operating these systems economically. The experiences, gained after the conversion, show that the companies as social institutions maintainers are able to work properly more efficiently, with less government support while they meet the professional requirements, and the management who does the control is competent
and innovative. -
Environmental Consequences of Efficient Use of Nitrogen Fertilizers
41-46Views:78Nitrogen fertilizer represents major economic burden. For this reason, although the efficiency of nitrogen utilization varies highly, its actual use generally remains at low levels; these averaging between 25 and 50%. We set up an experiment at the Oradea Research Station, using 15N labeled fertilizers, in order to investigate the possibility of increasing N fertilizer efficiency in winter wheat under irrigation conditions.
Fertilizers labeled with 15N allows us to individually determine its effect on yield formation, as well as the use efficiency of N from fertilizer following application rate and time. The amount of N derived from fertilizer as determined in straw and grain yield is high. When the labeled fertilizer is applied at tillering time, the values of this indicator rise when higher N levels we applied.
In separate experiments, we investigated a series of aspects connected to chemical fertilizer regarding the determination of the type of fertilizer, optimum time and rates of application; all these as a function of the special pedoclimatic conditions.
The results obtained in the field show that the effectiveness of N utilization in wheat is most variable and generally low, often ranging between 25 and 33%, owing to N loss within the system through leaching and NH3 volatilization.
A readily achievable increase in efficiency of 5 percentage points would result in considerable savings, and can be brought about by reducing nitrogen losses. The added benefits to the environment in terms of reduced ground/water contamination and lowered nitrous oxide (N20) emissions would also be substantial.
The figures for N fertilizer use efficiency (% N range from 35.5 to 72.6, the highest value being recorded with an N application of 120 kg/ha at tillering, when the previous crop was sunflower).

From the Concept of Sustainable Development to the Subsidies of Agricultural Environmental Management
354-361Views:73The most important aim of the study is to introduce the theoretical background of my PhD dissertation – agricultural environmental management –, in order to help the scientific foundations for my dissertation, which is in progress. For this reason I will try to clarify and systematize facts found in the special literature according to my own thoughts, from a new aspect.
In my study, I therefore attempt to introduce the theoretical background of sustainable development as pertains to the subsidies of agricultural environmental management (National Agricultural Environmental Management Program, National Regional Development Plan, agricultural environmental management measures). Having clarified the concepts I place sustainable development in the economic theories directed to the treatment of environmental problems, introduce where subsidies are within the environmental regulation implements and I dwell on to the institutional questions in the explanation. I then study questions of sustainable agricultural economics. Accession to the European Union has to be considered as one of the most important concrete motivities of domestically coming into prominence of agricultural environmental subsidies therefore I think it is important to study how the problematic of sustainable development, sustainable agricultural development and agricultural environment protection worked out in the EU. Finally I survey the main characteristics of domestic agricultural environment management programs fitting into the theories explained above, how the program adjusts to the theories of sustainable development and sustainable agricultural development.
In the dissertation I begin with sustainable development as the broadest theoretical background, then I survey a narrower category, the theories of sustainable agricultural development and how concrete agricultural environmental programs fit into the studied theoretical relations. -
Examination the users’s opinion of the electronic submission programme
47-51Views:66In Hungary the Agricultural and Rural Development Agency (ARDA) started to introduce electronic filling and submission of application forms for the two-hundred-thousand farmers in 2008. For submission it is recommended to be registered using by client gate. The producers' benefits have more results from electronic filling. Filling in and submitting the applications electronically ensure data will be correct and the application technically flawless and this can be the basis on the payment of former financial support and avoidance of sanctions or subtractions due to technical faults. The farmers may ensure the money more quickly. Based on survey is analysed the users of system conceive of the electronic submission programme.

Using the principles of precision animal husbandry in fishbreeding
283-287Views:197Aquaculture species such as fish, crayfish, molluscs and plats are a wide range of products, with continuously growing demand worldwide. The reasons for this is that they are cheap and easy-toraise protein sources, thus having significance in food supply especially in developing countries in tropic regions, moreover, the premium category foodstuffs in developed high income countries are also belonging to this category. World annual total production of 164 million tons (2009) are made up of two sources: 1) marine and inland fisheries landings that are stagnating for several years and 2) aquaculture which is growing dynamically with annual 6% rate between 2000–2009. The latter is accounting for nearly 45% of the total supply due to the depleting marine stocks caused by overfishing. Aquaculture is growing continuously also because the production is safe and can
be planned well.
Intensive fish production systems are the representatives of precision animal production, several types exist and widespread worldwide. The modern computerized temperate water recirculation plants with several thousand m3 capacity are widespread also in Europe because they make it possible to produce even the most valuable species whole year round. A key issue in the technical/feeding outlay is to meet the demands of the cultured species the best and the operation of the system is to be safe and cost-effective. One condition for this is intensification: enable to produce more product per unit resource input or effort. The facilities need significant amount of energy, thus renewable energy sources are to be favoured for which Hungary has comparative advantages. -
Vegetable production based on waste heat in closed greenhouses considering economic usage and competitiveness of the European Union
41-44Views:117The study investigates two professional fields; the questions of vegetable production in greenhouses, the necessary steam supply and heat regulations. The actuality of this investigation is provided by the planning of a combined cycle power plant of 2400 MW in Hungary. According to the plans the steam developing by generating electricity in the power plant can be used to intensify the vegetable production. In my current study I present the experiences and results gathered as member of the research and development team led by Mr. Dr. Sinórós-Szabó.

The role of green manure crops in Hungarian plant production
49-53Views:226According to the data of KSH (Hungarian Central Statistical Office), the sowing area of cereals in the crop year 2016 was over 2.56 million ha, on which winter wheat and maize were produced in a rate of around 50–50%. Regarding these data it is obvious that the domestic cropping structure has been simplified and become unilateral. This unfavourable crop rotation system causes several problems. The number of Hungarian livestock decreased in the past decades. The amount of manure was 24 million tons in 1960, but only hardly 4.5 million tons of organic manure was applied in 2016. Therefore, the importance of other possibilities, alternatives for organic matter recovery have become enhanced. This is especially important from the aspect of sustainable plant production. The fact that the European Union has introduced new directives for subsidiaries in 2015 has to be noted as well.
The objective of the set experiment is to find new technological solutions that are suitable for the execution of sustainable plant production by inadequate crop rotation, organic substance recovery conditions or under more unfavourable climatic conditions.

The influence of channel network silting up at Žitný Ostrov to range of interaction between surface and groundwater
23-31Views:98The movement of water resources, especially the possibilities of their regulation by interaction between surface and groundwaters are the subject matter of attention particularly during the occurrence of extreme hydrologic situation. This work presents the overview of knowledge and results which were achieved at IH SAS in this question. It can show the ways how to optimize the adjudicated processes which emerge during the requirement of emergency intervention. The solution of this task was located at the Žitný Ostrov area because this territory with their existence of channel network is suitable for studying the surface and groundwater interaction. The channel network at Žitný Ostrov was built up for drainage and also to safeguard irrigation water. The water level in the whole channel network system has an effect on groundwater level on the Žitný Ostrov and vice versa. It was been necessary to judge the impact of the channel network silting up by bed silts on the interaction between channel network and groundwater on the Žitný Ostrov. The aim was to evaluate the changes of bed silt state of Žitný Ostrov channel network and consecutively their influence on interaction processes between groundwater and surface water along the channels in the period from 1993 to present. The measurements of bed silt thickness in Žitný ostrov channel network had been started from1993, later they continued at selected profiles of three main channels – channel Gabčíkovo-Topoľníky, Chotárny channel and Komárňanský channel (for checking of the silting up variability). From 2008 the detailed field measurements of cross-section profiles aggradations along these selected three channels have been started. The objective of detailed field measurements was the determination of the silt permeability which is expressed by parameter of saturated hydraulic conductivity. This parameter was determined by two ways – as the saturated hydraulic conductivity obtained from disturbed samples of silt Kp and as the saturated hydraulic conductivity obtained from undisturbed samples of silt Kn. In the first case the granularity of silts was determined as a first step and then was computed their Kp from the empirical formulas according Bayer-Schweiger and Spacek. From undisturbed samples of silts which were extracted along the channels from top, middle and bottom layer of silts, were determined the values Kn by the laboratory falling head method. The valid values Kp on channel Gabčíkovo-Topoľníky ranged from
4,33 10-7 to 4,46.10-5 m s-1, on Chotárny channel from 5.98 10-5 to 2.14 10-6 m s-1 and on Komárňanský channel fluctuated from 1.93 10-6 – 6.09 10-5 m s-1. The valid values Kn on on channel Gabčíkovo-Topoľníky ranged from 5.21 10-8 – 4.18 10-3 m s-1 , on Chotárny channel ranged from 8.54 10-8 – 2.70 10-4 m s-1 and on Komárňanský channel fluctuated from 4.72 10-7 – 1.26 10-5 m s-1. The remarkable results were noticed by comparison of values of saturated hydraulic conductivity from disturbed and undisturbed samples Kp and Kn. On Chotárny channel the values of silt saturated hydraulic conductivity from undisturbed samples Kn approximately hundredfold decreased (from 10-6 to 10-8 m s-1). On Komárňanský channel the comparison of values Kp and Kn shown that the values Kn from undisturbed samples approximately tenfold descended against Kp.Simultaneously, the bed silts‘ impact on the groundwater recharge (saturated hydraulic conductivity of silt) was also examined. Determination of the total recharge amount was done by numerical simulation (model SKOKY) and by the so-called method of interaction formulas. These two approaches were applied at the Žitný Ostrov channel network. There were field measurements performed in monitored three main channels and adjacent to obtain correct input data. These characteristics were used for simulation and computation of total recharge along the channels. The total recharge amount was calculated for four alternatives of the surface water levels in the channel and the surroundings groundwater respectively. We chose four simplified variants with the same geological conditions in surroundings area of channels, only water levels of groundwater and in channels were modified. The results of the simulations seem to show greater impact of the silt in the case of outflow from the channels to the surroundings than the inflow into the channel from the surroundings.

How does the S-locus determining self-incompatibility in stone fruits work in self-compatible peach?
93-100Views:102The majority of stone fruit species are self-incompatible, a feature that is determined by a specific recognition mechanism between the S-ribonuclease enzymes residing in the pistils and the F-box proteins expressed in the pollen tubes. Failure in the function of any component of this bipartite system resulted in self-compatibility (SC) in many cultivars of Prunus species. Peach (Prunus persica (L.) Batsch.) is the only species in the Prunoideae subfamily that is traditionally known to be self-compatible, but its molecular background is completely unknown. Isoelectric focusing and S-gene specific PCR revealed that SC is not due to functional inability of pistil ribonucleases. We hypothesize that SC may be a consequence of a kind of pollen-part mutation or the action of one or more currently unknown modifier gene(s). Only two S-alleles were identified in a set of peach genotypes of various origin and phenotypes in contrast to the 17–30 alleles described in self-incompatible fruit trees. Most important commercial cultivars carry the same S-allele and are in a homozygote state. This indicates the common origin of these cultivars and also the consequence of self-fertilization. According to the available information, this is the first report to elucidate the role of S-locus in the fertilization process of peach.

Study of plant production modells with different intensity in winter wheat production
51-60Views:102The 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). -
Effects of cultivation methods on some soil biological parameters of a meadow chernozem soil (Vertisols)
61-66Views:78The effect of extended drought conditions on soil, the unfavourable cultivation technologies and the application of chemicals have been enhancing the processes of physical and biological soil degradation, so the fertility of soil is gradually declining.
The effects of two cultivation methods – traditional ploughing (TP) and conservation tillage (CT) – on the biological activity of a meadow
chernozem soil were examined in a long term experiment. Different parameters of the biological activity of soil were determined. These are
the numbers of total bacteria, microscopic fungi, aerobic cellulose decomposing bacteria, as well as the activities of some important soil
enzymes and CO2 production.
Conservation tillage seemed to be a more favourable cultivation method for the majority of microorganisms, the activities of urease and
dehydrogenase enzymes and CO2 production, compared to the traditional ploughing system. These parameters increased significantly,
especially in the upper layer of conservation tillage plots. Concerning the plant cultures, the majority of microbiological parameters were
higher in the soil of vetch (Vicia sativa L.) depending on the cultivation methods, so involving the pulses to the crop-rotation seems to be
very important in this soil type.
According to the ninth year’s results, the importance of conservation tillage as a means of protecting the soil biological activity in meadow
chernozem (Vertisols) can be established; it was proven by microbiological investigations. -
Regional strategies serving competitiveness
97-101Views:117In my study titled “Regional strategies serving competitiveness”, I examine the regional strategies whose development and implementation in practice play a determinant role in the medium- and long run economic and social development of the given region. The study primarily focuses on the infrastructural basic investments that are essential from the aspect of creating a knowledge-based information society. The study also deals with a stakeholder analysis used by investors in order to focus on the quality of state administration and institution system.

Complexity of ecosystem services in agricultural fields, in particular the biodiversity
43-51Views:123Since the Convention on Biological Diversity a lot of papers have been published how to measure and value biodiversity. In the last decades publications on agro-ecosystems become more frequent and play a significant role in the provision of ecosystem services. There is a uniform definition for biodiversity in general, however, in terms of agro-ecosystems and their services (including biodiversity) many weaknesses can be identified. The objective of this paper is to explore some of these problems with special regard to different definitions and terms and to the farmland ecosystem services. One solution could be to adopt a more complex system which has some ecological and environmental components (air, water and soil pollution) and also takes in to consideration the efficiency of agricultural production.

Beginning of a New Era in Hungarian Crop Production
87-100Views:63The examination of Triticum monococcum, which was observed on an ancient region, and its ancient quality made me develop a new quality analysis system.
The Triticum Monococcum frames the new standard of this ancient quality.
The quality of diploidea – tetraploidea – hexaploidea series, which was arisen by the wheat poliploidization, gradually decreased. The quality of diploidea species diffuse around the standard.
The micronutrient content of tetraploid species gradually decrease, the hexaploid species and the Triticum Aestuvum micronutrient content 20-70% less than the ancient quality’s. -
Comparative Evaluation of the Temperaments of Charolais and Hungarian Grey Steers
14-19Views:92Animal breeding increasingly lays claim to the theoretical and practical knowledge of applied ethology. The authors’ aim was to evaluate and compare the temperaments of Charolais (CH, n= 10) and Hungarian Grey (HG, n= 10) steers, and also to determine the correlation between their temperament scores and flight speed scores. Temperament was evaluated by the results of the scale test (assessing of behaviour in a 1-5 score system, while the animal is standing on a scale for 30 seconds) and flight speed test (minutes it takes the animal to move a set distance of 1.7 m when leaving the scale), on three occasions (1, 2, 3). Data management was done by SPSS.10 (ANOVA, Mann-Whitney-test, Spearman-correlation). Results of the scale test differed significantly between breeds at the third measurement (CH: 2,9 scores; HG: 1,4 scores; P<0,01) and when evaluating the three measurements together (CH: 2,0 scores; HG: 1,37 scores; P<0,05). Concerning of flight speed score, there were significant differences between breeds of steers at each measurement (1. measurement CH: 2,77 s; HG: 4,09 s; P<0,05; 2. measurement CH: 2,89 s; HG: 5,01 s; P<0,01; 3. measurement CH: 2,46 s; HG: 5,33 s; P<0,01) and overall (CH: 2,71 s; HG: 4,81 s; P<0,001). In the case of both breeds, evaluated by measurements and overall, a negative correlation was calculated between temperament score and flight speed score, but this was significant only in three cases: CH1 (n=10) r= -0,75; P<0,01; CH1+2+3 (n=30) r= -0,44; P<0,05; CH+HG1+2+3 (n=60) r= -0,33; P<0,01). Results indicate that Hungarian Grey steers are calmer than individuals of Charolais. Animals behaving calmer on the scale left the scale, more slowly. The authors propose the use of these temperament tests in Hungarian breeding practice, in order to select too temperament animals.

Contradiction in the agrofinancial regulation of agricultural producers
97-107Views:85Hungary is a country of favourable conditions with agropotential, for this reason the regulations regarding agriculture is constantly the bone of legislative contention. The
purpose of this study is to present the actual agropotential contradictions concerning the agricultural producers, specifically focusing on certain problems without any detailed representation of the valid rules of law. The agrofinancial anomalies referring to agricultural producers can be found mostly in the system of the personal income tax (allowance, tax immunity), the value added tax (special agricultural legal position) as well as the social insurance.
The severity of the problem is supported by the agricultural producers’ behavioral types of paying taxes, globalisation process of these days and our place in the European Union. The resolution of the contradictions in agriculture does not lie by any means in the proper way of making the rules of the law of taxation, but in a comprehensive economic policy, which is to be waited for.
