Impact of precision irrigation on the unit income of maize production
157-162Views:83The study of the economic/economic impact of precision farming should be a priority area in digital agriculture, as the results, profitability, and efficiency indicators can have a significant decision-support effect on the development of both the agronomic and the technical regions of individual farms both in the longer and shorter term. Individual firms, companies, farmers, and family farms quantify the effectiveness of their farming processes. The modern age offers the possibility of digitally recording all the elements of farming technology, making it possible to analyse the cost-effectiveness of a farm more effectively and, in some cases, to carry out more detailed analyses. Nevertheless, the number of farms demonstrating their profitability with such precise economic calculations is still minimal.
Our analyses were conducted on a 56,02 ha field of Balogh Farm-Tépe Ltd. The agricultural operations carried out were fully documented so that the inputs (seeds, fertilisers, pesticides, crop enhancers) were recorded in coordinates and kind, as well as the specific yields, grain moisture data, irrigation norms, and irrigation rotations. At the same time, the company's owner provided the data's monetary value. The main econometric indicators (yield, production value, cost of production, income, cost price) related to the evaluation of the enterprise management were evaluated along with the spatial data in the irrigated and non-irrigated tables. Our calculations show that a given year's climatic and market characteristics fundamentally determine the cost and income relations of a plot of land (and thus of an entire farm). In addition to additional inputs, introducing some elements of precision farming and intensification and increasing yields improves yield security and allows for excellent yield stability.

Study of factors controlling the amount of 0.01 M CaCl2 extractable Norg fraction
437-449Views:207The use of new methods describing the “readily available” nutrient content of the soil is spreading on a global scale. The 0.01 M CaCl2 extractant is a dilute salt solution in which the easily soluble inorganic (nitrate-N and ammonium-N) and organic N fractions, P, K and micronutrients are also measurable. The 0.01 M CaCl2 has been tested in the University of Debrecen, Institute of Agricultural Chemistry and Soil Sciences since the 90’s. The results of the researches related to organic N fraction, performed in the last decades, and the results of the present study (originating from the long-term experiment of Karcag, 2007–2009) can be concluded as follows:The measurement of easily soluble and oxidizable organic nitrogen (Norg), besides inorganic fractions, could improve the nutrient management.The amount of the Norg fraction is determined by the soil conditions, therefore it is considered to be a site-specific parameter.Management practices and cropyear affect the amount of Norg as well. The present research confirmed that, the effect of fertilization on the amount of Norg can be explained by the changing of the yield (related to total biomass production), while the effect of cropyear is related to the differences in mineralization circumstances and yield as well.The measurement of the Norg fraction is increases the accuracy of N-supply, therefore it could prevent the environmentally harmful excess N application as well. -
Development opportunities for storing and displaying of spatial data in long-term experiments
81-86Views:131Long-term experiments are required to evaluate the impact of irrigation, nutrient utilization, and year factor as well as to assess the potential consequences of climate change. However, in the long-term experiment, it may be necessary to display spatial data for each parcel, either for investigation of soil heterogeneity or presentation. This article aims to provide help for researchers working in long-term experiments for storing and displaying spatial data.
After the outlines of each experimental site were measured with GPS, a spatial database has been created in Quantum GIS. Then, a filter script in R statistical environment using RStudio graphical interface was written. The script helps avoid the QGIS data input interface so that large data can be attached to each parcel directly and as a result there is no need for a separate data entry, only the basic statistical database.
The created GIS database can be used in many ways; it can be exported to KML file format that can be displayed using Google Earth. It is possible to view exported KML files in Google Drive with importing them to Google My Maps application, and with that a browser can display the map. With the Google Drive the maps can be shared within the research group, additionally the outlines can be edited and it is possible to upload the measurement data to the attributes table to existing empty table columns. The map created in Quantum GIS can be used for presentation purposes.

Technological development of sustainable maize production
83-88Views:159In our research we examined the effect of the hybrid, the nutrient supply, the number of plants and the abiotic factors (temperature, amount of precipitation) on the yield, crop quality and yield stability of maize. We devoted special attention to the natural nutrient utilization ability and fertilizer reaction of maize.
The experiment took place in Hajdúszoboszló on chernozem soil, on a nearly eight ha field. The size of one plot was 206 m2, this it was a half-industrial experiment. We tested six hybrids with different genetic characteristics and growing seasons. I analysed the correlation between the nutrient supply and the yield of maize hybrids with control treatment (treatment without fertilization) and with N 80, P2O5 60, K2O 70 kg ha-1 and N 160, P2O5 120, K2O 140 kg ha-1 fertilizer treatments. Yield increasing effect of the fertilizer also depended on the number of plants per hectare at a great extent. The number of plants of the six tested hybrids was 60, 70, and 80 thousand plants per ha.
In Hajdúszoboszló, in 2016 the amount of rainfall from January to October was 605 mm, which was more than the average of 30 years by 160 mm. The yield of hybrids without fertilization changed between 9.63–11.6 t ha-1 depending on the number of plants.
The six tested hybrids is 10.65 t ha-1 in the average of the stand density of 60, 70 and 80 thousand plants per hectare without fertilization, while it is 12.24 t ha-1 with N80+PK fertilizer treatment. That increase in the yield is 1.6 t ha-1, it is significant.
Da Sonka hybrid is sensitive to weather, it is able to produce 6 t ha-1 additional yield in case of favourable condition. However, it has a low stress tolerance. The most stable yields were observed at Kamaria and Pioneer hybrids. The effect of vintage is also an important factor on the yield. In average, the yield of maize was 6.81 t ha-1 in 2015, which was a drought year and 11.86 t ha-1 in 2016 that was a favourable year. -
Assessment of energy generated by biogas production in the educational industrial unit of the University of Szeged, Faculty of Agriculture, with special regard to biomass originating from agriculture and the food industry
137-140Views:104The importance of waste treatment is increasing. Environmental aims are the main driving force. Stricter regulations for landfills lead to the development of alternative treatment methods for waste. For agro-mechanical research, wastes from animal rearing and the food industry, secondary-tertiary biomass, is of deep concern. Available technology is versatile and relatively simple to use as a reliable and effective means of producing a gaseous fuel from various organic waste. The most common application has been the digestion of animal dung, agricultural, and food-industrial waste. This was studied by our department in our pilot farm of our Faculty. The 50-dairy cow, family sized model farm was built in the summer of 1991, as a result of a Dutch – Hungarian cooperation, on the property of the Faculty. The new pig farm, with 30 sows, and the new goat farm, with 100 nannies, was given to the Faculty on 25 April 2001. On the basis of livestock data, the annual dung production and the producible energy were determinate. The energy was calculated by biogas production coefficients in literature.

Hungary’s correspondence with the EU regulations regarding liquid bio fuels
119-128Views:90During the recent years researchers from different countries have found that our environment is at risk. It has been recognised by the leaders of the member countries and they have made decisions together concerning environmental protection in several agreements, contracts. Unfortunately, these decisions have been weakened and adumbrated on numerous occasions by certain interests.
However, the energetic exploitation of the biomass has been supported by the economic and social changes of the previous years, more specifically, that of the bio fuels. The significant increase in the price of the traditional energy sources, the import dependency of the countries, the foreseeable exhaustion of the resources, the changes occurred due to joining the EU are all such problems that facilitates the application of bio fuels, as a good solution.
Our country decided to modify the then existed bio fuel component rate of 2% to 5.75% which has to be achieved by 2010. Since then, in March 2007 it has been expanded to 10% until 2020 (concerning energy content). This decision was taken knowing that this year (2006) the bio fuel rate has been 0.5%. However, the rate of 2% has not been achieved even in the EU. One can understand that the implementation cannot be fulfilled without significant political decisions and support. The main reason for this is that the price of bio fuels is not competitive with the present fossil-origin energy prices in Hungary. So in 2007 several regulations were modified. The most important one is perhaps the regulation of the revenue tax, which caused the successful tax-differentiation concerning bio fuels in more member states between 2007 and 2008. Its essence is that the revenue tax is not decreased, but if the fuel does not contain a bio fuel component of 4.4 bulking percentage per litre, „punishment” tax has to be paid. Moreover, on behalf of the implementation, regulations concerning bio fuels and bio fuel components are improving
At present the production and the application of bio fuels without any support are not economical yet. That is why it is important to emphasize the support policy of our country. After joining the Union, the new members can receive some shares from the direct disbursements, but only a tan increasing rate, we can achieve the 100% in 2013, though there is an opportunity for national contribution. Energy plants produced in agriculture receive separate supplementary support which is an advantageous opportunity for the farmers of the sector. Bio fuels cannot only be supported through agriculture, of course, but by research development, investment etc.
All in all, it can be concluded that Hungary seeks to fulfil the EU responsibilities taken and by this, to contribute to the maintenance of the sustainable progress, decrease of environmental pollution and the import dependency of energy sources. -
Effect of vitamin e and selenium supplementation on the antioxidant content of milk and dairy products in dairy cows
9-12Views:169In 2007, the aim of the Ányos Jedlik program and the call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants - in this case: vitamin E and selenium – used as feed-additives can increase the antioxidant content of milk. The milk with an increased level of vitamin E and selenium content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E and selenium as feedadditives can significantly increase the amount of vitamin E and selenium in the milk and also in the diary products.

The hydric stress influence on quantityand quality of the maize yield in the Crisurilor Plainconditions
21-27Views:136The paper is based on the researches carried out in an experiment placed on the preluvosoil from Agricultural Research and Development Station Oradea, Crisurilor Plain during 2008–2011in the following variants: V1=Irrigated, without irrigation suspending; V2=Irrigated, irrigation suspending in May; V3=Irrigated, irrigation suspending in June; V4=Irrigated, irrigation suspending in July; V5=Irrigated, irrigation suspending in August; V6=Unirrigated. The hybrid used: Fundulea 376. In the variant with optimum irrigation, water reserve on 0–75 cm depth was maintained between easily available water content and field capacity. Pedological drought was determined every year and the irrigation was also needed. The irrigation determined the increase of the total water consumption and yield gain in comparison with unirrigated variant. Irrigation suspending in different months determined the yield losses very significant statistically. The biggest protein content was registered in the variant without irrigation suspending; the values registered in the variants with irrigation suspending in May, June, July and August and in the unirrigated variant are smaller, with differences statistically assured. There was a direct link between de Martonne aridity index values and water consumption, yield and protein content and an inverse link between pedological drought and yield quantity and protein content. These are the arguments for irrigation opportunity in maize from Criurilor Plain.

Theoretical and comparative study regarding the Galerkin-Vlasov method use for study the free vibrations of wood flat plate
223-228Views:82As for the historic record of the problem related to the study of flat plates, the first results were out for publishing at the end of the 18th century, the beginning of the 19th century, having Chladni E, Strehlke, Konig, R, Tanaka S, Rayleigh L, Ritz W and later on Gontkevich V, Timoshenko S, Leissa as pioneers. Each of the above mentioned authors have had significant contributions regarding the development of methods in order to solve the plates and establish some rigurous solutions of their differential equations of equilibrium.
The making of constructions, machines and different high-perfomance appliances, whose functioning should take place in safety conditions, have required theoretical studies of rich complexity, as well as practical experiments, within which the problem of their free and forced vibrations represent an important category in the respective theme of research. -
Management of phytopathogens by application of green nanobiotechnology: Emerging trends and challenges
15-22Views:334Nanotechnology 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.

Decreasing Energy and Water Use in the Meat Industry
24-28Views:80The technology supervisions are needed from time to time in order to involve the new research results, experience, new technologies and equipments organising principles into the production and to make it cheaper and with less expenditure to increase the profitability and competitiveness. In the course of our investigation we aimed the analysis of the traditional technologies and improving of it. In this article we detail the heat treatment curing process. We applied the principles of experimental design for the determination the main influencing parameters in the processes. Then we made simulations and modelling in seeking for the environmentally better technology programs. We developed a method for measuring the temperature development of products with small diameter using the similarity theory in unit operation. In the course of the analysis of the heat treatment processes we could state that the heat treatment time can be reduced significantly by decreasing the size of the product and choosing the right ratios among the surface heat transfer intensity, ambient temperature and involving the lethality obtained during the cooling phase. The total sparing were about 10-20%. We solved the problem associated with the sensor placement error using a plastic material (metamid). We establish a curve between the real product temperature and plastic rod temperature by which the monitoring of the process became more accurate. We determine the size modification for different product sizes. In case of curing we observed very similar phenomena. For the determination of the diffusion coefficient we adopted the Ball-method not using in this field till today. We could reduce the excess saltiness and loss of NaCl with about 5%.

The importance of selenium in the living world and in the scientific research
278-286Views:239Presently, selenium (Se) is one of the most investigated microelements. It has an important proven role in many vital processes. Directly or indirectly, selenium deficiency can play a role in the development of many diseases. On the other hand, the concentration range in which selenium is essential is narrow; there is a narrow gap between necessary and toxic content in dietary intake. In this context, selenium contamination poses a further health risk for people if they live near the industrial areas and mining activity.
In this paper, we comprehensively introduce the very important trace element selenium. We studied the base parameters, deposit, analytic and deficiencies, problem of contamination and also the solution of contamination problems of selenium. -
Feeding questions of organic lamb fattening
155-160Views:106Organic farming has done in line with conventional farming in the Karcag Research Institute of DU CASE since 2001. Our organic farming activities were enhanced with sheep farming and
grassland management in 2005. We started our study of technology development of organic lamb fattening and the treatment of its economic effect this year. Our goal was to develop
the elements of the technology to reach a more efficient organic lamb fattening. We also studied what economic advantages the organic sheep farming could realize in the present economic environment. Our studies were carried out between 2005 and 2007. We established that the excellent ewe feeding (good quality of fodder and silage) can decrease the lamb feeding cost between the 2nd and 8th weeks of the lambs’ life. We established that the
yield of convention lambs are significantly higher than the yield of organic lambs. The cost of organic lamb fodder is significantly lower than the cost a convention lamb fodder, but the profit was higher in the case of convention lamb fattening. The organic lamb fattening technology (without extra price) is not competitive to the conventional lamb fattening technology. We think that the profitability of organic lamb fattening is significantly less than of the convention one. The organic lamb price should be 20-30% higher than the other price to be competitive. Unfortunatly there is only a little demand for organic lamb and there is no difference between the prices of organic and convention lambs, so organic sheep farmers have worse economic circumstances than conventional sheep farmers. -
Use of molecular marker methods in the classification of bamboo taxa: A review
51-59Views:260Bamboo plants are currently attractive to researchers because of their versatile uses. Understanding the bamboos’ genetic level is needed to develop new varieties. Taxonomic identification is the basis for plant development. Bamboos were identified as their taxonomical morphological characters which are dependent on environmental factors. Molecular Marker techniques can be used to perform accurate genotype identification, which can be used for genetic diversity analyses. The RFLP, RAPD, AFLP, SSR, ISSR, iPBS, SCARS, SCoT, SRAP marker systems have been shown to be able to efficiently determine the genetic diversity of bamboo species based on genotyping. This paper summarizes research that aims to analyze the genetic diversity of bamboo species on a molecular basis.

Methodological development of the determination of the compost mixture ratio
29-33Views:98The mixing rate of the compost raw materials basically determines the procedure of degradation. In most cases, in practice the real mixing ratio is not equal with the counted ratio – which based on the C/N ratio – and the check of the fulfilled mixing is not possible.
The homogeneity of the prism is also one of the fundamentals of the effective degradation process. There is no available method to determine the homogeneity of the compost prism.
During our research we examined the reflectance values of different compost mixtures where sewage sludge and rape-straw were used as raw materials.
According to our results we built up a regression model which gives the ability to determine the mixing rate (in 5% margin of error) and makes possible to check the homogeneity of the prism together with the access of immediate action. -
Ecological Conditions of Agricultural Land Use in Transcarpathia
190-194Views:97The unbalanced anthropogenic effects for several decades resulted in significant technogen damages in the ecosystem of Ukraine. Excessive land development, including the use of slopes, effected the disintegration of the natural balance of lands – arable-lands, meadows, forests, and watershed areas – producing quite a negative effect on the landscape’s nature itself. It has to be stressed that according to other indexes, too, agricultural lands show a tendentious deterioration.
Erosion, caused by water and wind, is one of the most influential factors in the degradation of agricultural soils and in the reduction of the productiveness of benefital lands. Nowadays the degree erosion became significant and it directly endangers the existence of the soil which is a principal chain-link of the agricultural cultivation as well as an irreplaceable element of the biosphere.
The social and political changes in Ukraine’s life demand fundamental modernization in the land utilization both in ecological and in economical aspects. However, these aims can be realized only if, during the developments, we base on the up-to-date results of agronomics, and we do further research in the relations of agricultural land use and environmental protection. According to the latest theories, rational and environmental-safe agricultural production relates to the optimum correlation of the natural- and agricultural- ecosystems as well as to the reconstruction of agricultural areas built on the basis of environmental protection. -
Long term researches regarding the irrigation influence on sugarbeet crop inthe Crisurilor Plain
11-15Views:158The paper is based on the researches carried out in the long term trial placed on the preluvosoil from Agricultural Research and Development Station Oradea, Crisurilor Plain in during 1976–2012.
The soil water reserve in 0–75 cm depth decreased bellow easily available water content every year and in 32% of years the soil water reserve decreased bellow wilting point. For optimum water supply an irrigation rate of 2665 m3 ha-1 (variation interval 500–5090 m3 ha-1) was needed.
The irrigation determined improving of water/temperature + light report (Domuta climate index) with 47.4% in average in the period May–September. A statistically very significant connection was quantified between this indicator and the yield.
Daily water consumption increased in the irrigated variant, the biggest difference in comparison with unirrigated variant was registered in August, 86% in comparison with unirrigated variant. As consequence, the value of the total water consumption increased with 50%, variation interval was 11–154%. The irrigation covered 37.8% of total water consumption, the variation interval was 8.3%–67.9%.
The yield level of the sugarbeet increased in average with 61%, the variation interval was 9–227%. Standard deviation was lower in the irrigated variant and this emphasizes an improve of the yield stability with 25.1%. The sugar content of the sugarbeet roots from irrigated variant increased statistically very significantly in the droughty years and differs significantly in the rainy years.
Water use efficiency increased in the irrigated variant with 7% and irrigation water use efficiency was between 7.9 kg yield gain 1 m-3 irrigation water and 17.4 kg yield gain 1 m-3 irrigation water.
The positive influence of the irrigation on microclimate, water consumption, yield level, stability and quality and on water use efficiency sustain the need of the irrigation in sugarbeet from Crisurilor Plain.

Comparison study of student with special educational need in elementary school
71-76Views:168The aim of this lecture is to observe the status of students with special educational needs (SEN) in Europe and Hungary. The European Union has made tough decisions in financing and educating disabled people, so they can be integrated into the society. According to the European directives, Hungarian jurisdiction and educational politics tend to follow the pedagogical processes. The relevant juridical and economical laws for SEN students have already been implemented. The number of students with SEN in Europe increases permanently, so it is reasonable to detect their controversy. Despite this fact, differences can be experienced in teaching methods among primary schools, as a result development of SEN students can be different. The aim of this study to compare the motor skills of SEN students in two different primary schools, with different pedagogical program. My research base were the Ferenc Móra primay school and Gyermekház alapítvány primary school in Budapest. My main question was, if a specially developed program targeted SEN students can increase their motor skills. Studying the girls in the 2 age-groups, we have not experienced significant differencies out of the 3 motor tests between the control and the experimental groups.
Studying the boys in the 2 age-groups, we have experienced 3 significant differencies out of the 3 motor tests between the control and the experimental groups. SEN students, who have been taught in segregated form with the help of ’Alapozó Terápia’ – a special therapy – achieved better motor skills. The study makes recommendation to primary shools how to organise trainigs for these students. -

A review on the trend of livestock breeds in Laos
227-237Views:446When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still the critical component of animal breeding in Laos. Thus, there is a need to review the previous, current situation and prospects for Laos' livestock production. It aimed to study the different traits among the existing dominant local and improved livestock breeds (cattle, pig, and goat) and a more in-depth study on the livestock sector's previous evolving and prospects. Our findings revealed that the general trend of livestock population in Laos increased year-by-year for over 45 years, except for 1995 to 2000. It was decreased by almost 22% due to the new national strategy on economic revolution. The first foreign breeds were introduced into Laos, i.e., Large White, Landrace, and Duroc in 1980, Red Sindhi bulls in 1998, the frozen semen of Red Brahman 2003, and Bach Thao goats between 2001 to 2003. Unfortunately, many data are still not precise for introducing other foreign breeds like Boer goats, Thai Grey and Red Brahman. There were many missing data on the improvement of livestock breeds in Laos, including the local and improved breeds' reproductive and productive performance, which needs more study and research. We conclude that the semi-complex farm operation should be applied to improve livestock breeding and their productions in Laos.

Economic Aspects of Rural Tourism
55-71Views:87necessary to ensure the livelihoods of those leaving the agricultural sector and to supplement the incomes of those working in agriculture. I research rural development in four settlements in Hajdú-Bihar County, in Balmazújváros, Hortobágy, Tiszacsege and Egyek, all bordering Hortobágy National Park.
There are many alternative income sources in settlements in the Hortobágy area, such as organic farming, production herbs, hungaricums, small animals and arts and crafts, as well as rural tourism. Rural tourism is not for subsistence, but a supplementary income source, mainly available during the summer time. I made a survey of rural hosts in the four examined settlements, and according to my results, I constructed a model reflecting the cost-benefit relation, as well as the payment period conditions of rural tourism. I am going to show whether it is worth dealing with rural tourism, and if yes, under what conditions. Rural tourism contributes to the maintenance of rural modes of living, in this way it has significant cultural, economic, ecological and social aspects, as well. It is crucial for settlements to create the appropriate conditions needed for joining rural tourism, if it is worth joining at all, and to realise investments for all these. Rural tourism has strict requirements for the levels of environment, infrastructure and services. Studying the Western-European practices, Hungary is lagged behind in the conditions of rural tourism and rural hosts have done their activities mainly out of necessity and not to maintain traditions. Rural tourism may result in success only by co-operation and over the long-run. -
Farms in the system of European supportpolicy
79-83Views:91Common Agricultural Policy (CAP) has been having a great past, it is over numerous direction and structure changes in the last half century. After the Treaty of Rome, the harmonization of he agricultural structure and the production of Member States has been launched, during which the economic changes in the world and in Europe were continuously being kept track of. By using common experience, they strived to develop an agricultural sector that supplies the Member States of the Community with food, while the competitiveness and living circumstances of family farms are being improved. The general directions outlined in Stresa in 1958 were significantly redrawn owing to the transformed market conditions and EU accessions. The subsidization of family farms and the improvement of their profitability are having a stressed importance nowadays, too. Our country, as the fully qualified member of the European Union tries to meet its obligations undertaken in the accession treaty and therefore to develop an agricultural sector carrying out diversified agricultural production with a healthy age structure. The aim of the study is to specifically overview the issue of common agricultural policy by stressing the main development points and to introduce the Hungarian conditions of family farms. Besides, there will be an evaluation of the research works examining the income conditions of family farms in the North Great Plain region.

The status of the Hungarian Merino sheep breed compared to the other merino breeds
151-156Views:289Merino and Merino-derived sheep breeds have been widely known and distributed across the world, both as purebred and admixed populations. They represent a diverse genetic resource which over time has been used as the basis for the development of new breeds. In spite of this, their gene-pool potential is still unexplored. The Merino sheep represent the most important sheep resource of the Hungarian husbandry. It has the largest amount of individuals between both of the stock and commercial flocks. But in Europe the Merino stocks went through a drastic reduction in number. Thus these breeds became endangered in several countries as well as in Hungary. In this study we would like to present the recent status of different Merino breeds of the world to ground our further phylogenetic research with the Hungarian Merino breed.

Evaluation of the Green bean variety candidate BU-16
75-81Views:88This study presents the results of the variety comparison trials conducted with the French bean variety candidate BU-16 on sandy soil, during two years at the Research Center of the University of Debrecen.
The outstanding characteristics of this variety candidate are the early maturity, the showy pods (yellow, straight, cylindrical cross-section „pencil bean”) and the high yield potential.
The experiments were conducted with a randomized design, with five varieties and four replications. The varieties (of which two are foreign and three are domestic) were as follows: BU-16 fj, Maxidor, Paridor, Hungold and Budai piaci. The individual plots were 2 m wide and 4 m long. The seeds were sown at a density of 30 germs per m2, with a row spacing of 50 cm.
The following parameters were taken: time of flowering, time of green maturity, plant height, height of the lowest pod above ground level, number of pods per plant, distribution of the pods by the state of development (20 plants), usable pod length (1 kg of standard crop-yield), yield per hectare based on the number of plants per plot. The experiments were evaluated statistically with Excel and SPSS softwares.
Results obtained with the variety candidate BU-16:
– The time from the emergence to green maturity is 45 to 46 days, which is short as compared with the other cultivars studied.
– Plant height is 38cm (two years average), which is among the highest ones, together with Paridor.
– The pods are set high above the ground level similarly to Paridor, the height of the lowest pod is 19 cm.
– The average number of pods per plant is 13 (two years average) similarly to Paridor and to Maxidor.
– The distribution of pod size in 2007 is as follows: 68% of the pods of BU-16 is of the standars size, which is a good rate. The value of this trait for the other varieties is 60 to 63%, except for Paridor, the value of which is similar to that of BU-16.
– The usable pod length (10 to 14 cm) is 63% in 2007 and 84% in 2006. Similar pod length rates were obtained for Maxidor, while the rate for Paridor is as high as 91%.
– The total yield and the standard yield of BU-16 is among the highest ones.
According to the results obtained and presented above, the variety candidate BU-16 is the earliest maturing among the varieties tested with high yield potential which, however, is not significantly different from that of the others. Significant differences can only be detected in plant height and the number of pods per plant. Considering the results, BU-16 is to be further tested.
