Awareness and adoption of a nurse sow management system among small-scale pig farmers in Nakuru County, Kenya
113-120Views:84This study aimed to assess the level of awareness and adoption of nurse sow management strategies among small-scale pig farmers in Nakuru County, Kenya. The research included a survey of pig farmers who visited the Nakuru Agricultural Show in July 2023. A total of 139 farmers were interviewed within 5 days of the show. The corresponding author interviewed the respondents in a face-to-face engagement, where questions on nurse sow management were initially drafted in English and translated into Kiswahili, i.e. the second language in Kenya. The obtained results indicated that farmers came from two main regions of the county: the northern part (54.7%, 76/139) and the southern part (45.3%, 63/139). Levels of awareness and adoption were insignificant between the two groups (χ2, p<0.05). A major obstacle to the adoption of this strategy was identified as feed challenge at 77.7%; (108/139) and market issue at 59.7%; (83/139). This study identified important aspects and limitations that should be considered when developing sustainable productivity development strategies for Kenyan pig farmers. To assist the sustainable growth of small-scale pig production, the authors suggest government measures that shield farmers against exploitation of feed and marketing components, as well as advocating for effective breeding to increase live born.

Economic Assessment of Biodiesel Production for Hungarian Farmers
72-76Views:77Utilisation of oil of plant origin as a fuel is gaining acceptance in the European Union and elsewhere. Besides environmental protection, energy saving, and decreasing over-production of food. Additionally, the subsidisation of farmers and the development of rural sub-regions also contribute to its spread. This study specifically focuses on the direct effects biodiesel's raw materials and final products are now having on farmers, while reviewing and quantifying these effects. I have purposely restricted my analysis to these two elements of the biodiesel chain.
The biodiesel chain seems to be a great method for improving the economic and social position of participant farmers in many ways. Presently, the profitability of raw materials’ production looks to be the crucal point in the chain, and could be strengthened best with intensive, habitat-specific agrotechnic. It would only be possible to reach a favourable profit margin for farmers if yields reach unrealistic averages or if there is a significant hike of the 2000 producer’s price in the oil plant branch.
The main attraction of sunflower- and oilseed rape production lies in the stabilization of market conditions, which is not only gong to appear in oil plant branch but – thanks to the reduction of outputs – also in the cereal branches. Better economic safety for farmers may play a role at least on the same level as in plant production, which involves more risks than profit maximalization.
The reduction of the prime cost of biodiesel could be possible through the direct combustion of the whole oilseed plant or its residues or electricity production using them. Whereas energy demand for biodiesel production is low (appr. 5%) but it needs subsidization and the prices of natural gas and electrical energy presently look favourable in Hungary. Additionally harvesting and baling of the residues is technically problematic, which is why their use may seem to be reasonable just over the middle or long term. Another possible factor of cost reduction could be the centralization of some partial operations, which needs serious financial resources to reduce amortization cost per product, provided there be several biodiesel projects near each other during establishment. Creation and operation of a logistical system could also be a good method for improving the viability of the biodiesel chain, in order to optimize transport schedule and distances. However there are also some organizational difficulties in this case. -
Development of and Lessons from the Institution System of the Common Agricultural Policy in Slovenia
43-53Views:65The comprehensive agricultural policy of Slovenia during the setting-up of its agricultural institutional system for implementation of the Common Agricultural Policy has enabled the setting-up and design of the Paying Agency system to handle national and EU subsidies according to schedule. The country has acted on the advice of the European Union to use the introduction of SAPARD measures as a preparatory and experimental field for utilising subsidies after EU accession. Moreover, in addition to the importance of gaining practical experience in the field of implementation of rural development measures, Slovenia has recognised the necessity to become familiar with the application procedures for obtaining direct payments relevant for the largest group of beneficiaries, farmers. Accordingly, farmers have been practicing for 3 years how to fill in application forms, and have gained important experience before opening the most relevant resources. Also, the advisers supporting farmers to obtain subsidies have been trained during the last 3 years, in order to provide real assistance. EU agricultural subsidies are not divided among the Member States; there will be a strong competition not only with the new Member States, but also with the farmers of the more developed EU-15.
Slovenia has done its best in order to launch its farmers – due to the different development levels of the EU-25 Member States – into this very strong competition not like pupils, but at least like mature secondary school students. -
What does precision crop production hold for the future of soil science and plant nutrition?
411-421Views:215The concept of precision agriculture is straightforward at the scientific level but even basic goals are blurred at the level of everyday practice in the Hungarian crop production despite the fact that several elements of the new technology have already been applied. The industrial and the service sectors offer many products and services to the farmers but crop producers do not get enough support to choose between different alternatives. Agricultural higher education must deliver this support directly to the farmers and via the released young graduates. The price of agricultural land must be higher if well-organized data underpin the production potential of the fields. Accumulated database is a form of capital. It must be owned by the farmers but in a data-driven economy its sharing will generate value for both farmers and the society as a whole.
We present a methodological approach in which simple models were applied to predict yield by using only those yield data which spatially coincide with the soil data and the remaining yield data and the models were used to test different sampling and interpolation approaches commonly applied in precision agriculture. Three strategies for composite sample collection and three interpolation methods were compared. Multiple regression models were developed to predict yields. R2 values were used to select among the applied methods.

Application of GIS, precision agriculture and unplugging cultivation in plant breeding of Karcag
49-56Views:166In 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 financial 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.

Developing vegetable and fruit marketability potentials in Hajdu-Bihar county in terms of Hungary’s EU accession
60-69Views:83prearrangement, Hungary will be ready to join the EU by the 1st of January 2003. In the course of negotiations, the Government places special emphasis on agriculture, because Hungary is an agrarian country. Agricultural production is an important economic factor in Hungary: larger a factor in its economic structure than in those of the present EU member-states. In order to preserve competitiveness, Hungarian farmers and its
processing industry require information on the EU's CAP and other market influences.
In Hajdú-Bihar county the quality of agricultural products fall behind the standards of the European Union. There is no real solidarity among farmers, so they are left alone and are unable to meet higher, those standards, which were introduced by the structural changes of the market. Unfortunately, there is only one fruit and vegetable marketing organization (PO) in the county, although its necessity and effectiveness has been proved several times.
Within the framework of Rural Development, agricultural marketing is vital, because together with the local FVM institutes, it can help the farmers by providing consultation, information, and by marketing their products. Since fruit and vegetable growing has a considerable history in Hajdú-Bihar county, marketing activities can be effective in assisting both the farmers and the processing industry in preparation for EU integration. -
The status of conservation and management of indigenous sheep breeds in South Africa - A review
79-91Views:67Indigenous sheep breeds in South Africa play an important role in local food security and they are adapted to local conditions. Their genetic and cultural values have to be recognised for national importance. The conservation of these breeds is very critical as most of them are already classified as endangered. The South African government has the initiative to attempt the conservation of these animals; however, it comes with several challenges. In addition to funding, breed conservation demands farmers to understand and recognise the role of such breeds in society. This is especially crucial in the rural communal lands where breeds are kept. Farmers that raise indigenous breeds should be taught the necessity of maintaining the purity of these breeds. Indigenous sheep breeds in South Africa are not favored by the commercial farmers and thus they are more vulnerable. This review outlines the nature of sheep farming and the conservation status of four indigenous sheep breeds in South Africa. The effort and challenges that are met in current conservation arrangements are discussed. Moreover, we emphasise on the conservation techniques that are employed in South Africa.

e-services for the farmers
11-19Views:111Nowadays the different IT tools and use of the internet have appeared almost in every sectors of the economy, so it may give several benefits and help to the agricultural producers. In this article I give a brief overview about e-government and its’ opportunities, then I give a short description of a few important governmental and specialized administration on-line services which are provided to the farmers. According to many experts using of informatics may cause essential change in the operation of the administration because of the fact that the electronic administration may evolve. Generally speaking, today the egovernment services are already an indispensable device to the reformation of the public administration, the modification of services which suits to people's demands and the creation of the more adaptable, clearer public administration. The electronic
documents are free from formal errors which is either important for clients or offices. The cases can be arranged even from home in 24 hours of the day. The spread and success of the use of electronic services depend not only on the quality of services, but the IT readiness of the target audience is also very important factor. Unfortunately the affect of e-gap is bigger in case of the farmers. -
Yield of herbicide tolerant sunflower hybrids due to the different herbicide treatments
121-125Views:123Sunflower is our most important oil-plant grown on the largest area in Hungary. In Europe sunflower has been grown since the 16th century. In recent years sunflower growing area is between 450-500 thousand hectares. Weed management in sunflower production is getting more and more difficult in case of annual and perennial dicotyledonous weeds, especially in dry springs. Two active ingredients, imazamox and tribenuron-methyl could be a solution for farmers for the control of these weeds in herbicide tolerant sunflower hybrids (Christensen-Reisinger 2000, Hódi-Torma 2004, Nagy et al. 2006). Most of the farmers choose the Clearfield technology and the use of tribenuron-methyl herbicides. In 2009 imazamox- (IMI) and tribenuron-methyl- (SU) tolerant sunflower hybrids were produced on 200 hectares in Hungary, of which 150 hectares was IMI, while 50 hectares was SU-hybrids. Small plot experiments were carried out to investigate the phytotoxicity of herbicides on imazamox (IMI) and tribenuron-methyl (SU) tolerant sunflower hybrids under field conditions. At harvest we measured the moisture content of achenes and average yield.

Status and Prospects of Integrated Pest Management in Apple Production in Hungary
307-316Views:84Farming methods supporting the ecological function of agriculture will play an even more dominant role in the near future than they do now, as much in Hungary as in the rest of the EU.
Several farming techniques supporting sustainable development have already evolved, and in this essay, I deal with integrated production i.e. integrated fruit production in Hungary and its perspectives. I analyze both European and Hungarian regulations on integrated production and their development.
It is obvious that in the orchards of Europe, integrated production is gaining ground. We can expect the increased spread of this western trend to Hungary, too, because one of the conditions for remaining on the market will be a product from integrated production. However, we cannot expect any rapid increase in the future. In my opinion, there are three ways to propagate integrated production:
− changes in the approach of farmers;
− vocational training of farmers because of the greater „knowledge-demand”; improving the consultant network;
− strict monitoring of the production process. -
The Natural, Social and Economic Conditions and Opportunities for Development of Balmazujvaros, Especially in the Case of the Co-operative Kvaliko
77-85Views:88Balmazujvaros 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. -
Prospects of tobacco sector due to changing of union subsidy system
45-51Views:92Some 80% of the revenues from tobacco production originate from subsidies, therefore the existence of the tobacco industry basically depends on the system of subsidies. According to the current position, in the transitional period of introduction of the CAP reform (from 2006 to 2009) at least 40% of tobacco premiums shall be decoupled from the production, while the tobacco producing member states may decide to continue to pay the remaining 60% (or a less rate, depending on the rate of decoupling) in a coupled form. Tobacco premiums shall be fully decoupled as from the 2010 crop, however farmers will be eligible only for 50% of the subsidies, and the rest 50% shall be used for subsidising rural developments in tobacco producing regions (Radóczné, 2007).
This change affects the section very seriously. In EU-15 member states this system was introduced in 2006, which resulted in giving up tobacco growing by high percentage of the farmers (70-80% reduction of tobacco production in Greece and Belgium, and 45% reduction in Portugal). In Hungary – due to the small scale of the tobacco section – this rate reduction in production would jeopardise the existence of the section, therefore we are interested in maintaining the existing system of coupled subsidies to as a large extent and for as long time as possible.
This study shows the possibility of tobacco sector before and after introducing the changes in the system of subsidies, and formulates the most serious problems and roles of the sector. -
Development of an Agricultural Soil Information System
60-63Views:71Since the development of remote sensing nearly 60 years ago, there have been many applications for agriculture. Some have proved effective, while others have not succeeded in assisting farmers with problem solving. Recent advances in the spatial, spectral and temporal resolution of remote sensing as well as potential positive changes in cost and availability of remotely sensed data may make it a profitable tool for more farmers. The target area of my research program is the fields cultivated by Kasz-Coop Ltd. considering that this firm is one of the main agricultural firms in the region and its cultivated fields are quite heterogeneous.

Effects of fermented and supplemented chicken manure on the nutrient management aspects of an apple orchard
117-123Views:113AIt is a huge challenge for farmers worldwide to successfully increase the organic matter content of their soils and improve their water balance at the same time. Therefore, the main aim of the study is to develop and test organic-based nutrient composite materials that can be successfully used by farmers to increase soil organic matter content, improve water management parameters and implement water-efficient technologies. The study was performed in the orchard of the Institute of Horticultural Science of the University of Debrecen in Hungary (Debrecen-Pallag). The experiment was set up in a ten-year-old apple (Malus domestica ‘Pinova’) orchard. In the trial, fermented poultry manure and superabsorbent polymers (SAP) were used at different doses to study their effects on soil properties and fruit quality. Applied composite materials increased the nitrate and organic nitrogen content of the soil. Treatments did not affect the sugar content of the fruits but significantly and positively affected the individual fruit weight and the titratable acidity of the fruits.

Feeding questions of organic lamb fattening
155-160Views:92Organic 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. -
Plant clinic in Nepal: An overview
5-10Views:38Plant clinics play an important role in supporting farmers in growing healthy crops and achieving higher productivity in Nepal. The development and operation of plant clinics in Nepal are assessed in this study through a comprehensive analysis of the institution via literature review and interaction with key stakeholders. The plant clinic approach of the agriculture extension system started in Nepal in 2008, followed up with engagement with CABI and the Government of Nepal. Enhancement of farmers' knowledge and skill, encouraging sustainable farming methods, and ultimately increasing crop yields are the impact of plant clinics. However, there are some challenges faced during the implementation of plant clinics in the existing agricultural extension systems. In Nepal, the plant clinics are primarily operated by agricultural technicians with expertise in plant protection, as well as IPM farmer facilitators and community business facilitators after attending an intensive plant doctor's training. Plant clinics have been integrated into the agricultural extension system by agro-advisory service provider of the government of Nepal. Despite institutionalisation, policy support needs to be strengthened to ensure the sustainability of the different components of the (e.g., data management, validation, monitoring, localised content, etc.) plant clinic in Nepal.

Energy forests or vineyards?
237-240Views:72This paper primarily aims at giving an introduction to an alternative opportunity for vineyards owners many of whom have come to a
decision about elimination of their vineyards. The paper is focusing on the Mátra wine-region as a study area, which is the largest mountain
wine region in Hungary where more than one third of supported clearing of vineyards have been implemented in the last few years. The
abandoning of vineyards is explicable in more than one way such as very small average size of land or the increasing mean age of owners
etc. The fundamental reason is the chronic doubtfulness of the grape and wine market and the low level of overall profitability of production.
Grape production has a long tradition in this region, thus the disappearance of vineyards caused serious problems in land use through the
absolute lack of plans for the future. The popularity of biomass production in the press and the biofuel resultant from vine stocks raise
interest for short rotation forestry within a group of farmers. Short rotation forestry offers a new chance for some farmers to cut oneself adrift
from the harmful effects of the market of agricultural products. -
Coherence and connection between the good pond culture practice and the environment conscious management
60-73Views:76According to the data indicating the decline and restructuring during the past decade, as well as the trend in the European Union member states, it can be expected that the role of traditional agriculture and fish production in direct rural employment decrease further. This also values those strategic directions for restructuring that will lead fishculture from quantity driven to quality production along with sustainable development (i.e. environmental conscious production) and multifunctional farming. This way the economic and social tensions caused by the concentration of the production and labour output can be mitigated.
It is laid in the 1257/1999 Act on rural Development that farmers that enrol the agri-environmental scheme should follow the “Good Agricultural Practice” on the whole managed area. In case of agri-environmental schemes this is a precondition for which no grants are given.
The adaptation of “Good Agricultural Practice” in fishproduction,where it is called: “Good Pond Culture Practice” is considered important on the basis of the above mentioned. This programme is undertaken in co-operation with the Research Institute for Aquaculture, Fisheries and Irrigation, University of Debrecen, Faculty of Agricultural Economics and Rural Development and the Association of Hungarian Fish Farmers and Product Council.
The European Commission proposed the formulation of the European Fisheries and Aquaculture Fund (EFAF) for the period 2007-20013, which will replace the Financial Instruments for Fisheries Guidance (FIFG), but it also consists of several new elements and will be working differently, too. According to the proposal the budget for the Fund will be nearly 5 billion EUR (4963 million EUR). The development level of aquaculture and fisheries and the social and economic significance in the given member state will be considered when distributing the Fund between the Member States.
According to the plan the Fund is organised along five priority axes, of which the most important for the Hungarian fisheries sector is No. II: Aquaculture and the processing and marketing of aquaculture and fisheries products. The main measure areas are the followings:
1. investment support for aquaculture;
2. support for aquatic-environmental schemes;
3. environmental- and animal health issues;
4. investments in processing and marketing
In case of accessing support under measure area No. 2 farms are obliged to meet the requirements of the scheme beyond the “good management practice” for 5 years, which is to be supervised by the approved body of the Member State. For this reason our work is considered to be substantial.
Approval of the application of “Good Pond Culture Practice” is based on two elements: first the prevailing environmental and nature conservation regulations, as well as the list of controllable conditions in the new agri-environmental agreements are to be met. “Good Pond Culture Practice” are to be conducted on the whole farm area. Its main elements are:
- nutrition management,
- feeding,
- pond maintenance,
- stocking,
- harvesting,
- animal welfare (storage and over-wintering). -
Agri-environmental subsidies and the National Rural Development Plan
52-59Views:61The financing of agri-environmental target programs which is a prominent area in the EU became possible during the implementation and successful operation of the National Agricultural Environment Protection Program (NAPP) launched in 2002. Through this program we gained experience in the field agri-environmental measures which are financed from the Guidance Section of European Agricultural and Guarantee Fund in the European Union. The agri-environmental measures which are included in the National Rural Development Plan (NRDP) were implemented in Hungary in the fall of 2004 when the farmers handed in their application after the publishing of the related law. The NAPP financing is still active, but not significant since most farmers have chosen NRDP measures.
We are examining the experience of the above programs after studying some theoretical aspects of the agricultural economics and the EU laws. We try to analyse the most important experiences of NAPP including the legal background, news opportunities yielded by target programs, the financing, organisation, and institutional background. We will present the results taking into consideration the data of the winning applicants. -
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. -
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.

Examination of plant number and sowing date in different crop years
79-82Views:103We examinated three agrotechnical factors in 2011, 2012 and 2013 (sowing time, nutrient factor and plant density), as well as five different effects of genotypes on the crop of corn, on brown soil in the Hajdúság. The experiment was set next to the 47 main road in Debrecen, at the 6th kilometre stone.
In the present processing I would like to touch on the effects of sowing time and plant density, as I do not have the chance to present the whole experiment results here. It is true for all three years that the humidity factors differ from the long years’ average, so the genotypes had different reactions on it. According to our results we found out that the late sowing time’s result had the most successful crop yield result with 9975 kg ha-1, while examining the plant density the result of the highest plant density proved to be the best with 9967 kg ha-1.
We take the critical season in corns’ life cycle process into consideration when examining the results: June, July and August months’ humidity and temperature markers. According to the results in the tested 3 months we had 227 mm humidity with 10 days, when the average temperature was over 25 °C. The same factors in 2012 were 135.5 mm humidity with 37 days of average temperatures of 25 °C and in 2013 we recorded 102.5 mm humidity with 24 of these days.
Our goal is to help the farmers in the Hajdúság with the results of our sowing times, hybrid choice and plant density results.

Rheological evaluation of industrial tomato
137-140Views:122Today, tomato has the second largest harvesting area globally, and the fourth largest in Hungary. The importance of industrial tomato is growing year by year, and one of the most important tasks is to satisfy the needs of the industry. To meet these needs, the producer has to find the proper genotype, which can achieve up to 100 t ha-1 crop yield. This quality has high importance to be researched.
The experiment was carried out in the Botanical and Exhibition Garden of the University of Debrecen, with 3 examined genotypes. The planting date was 3 of May 2018. The harvesting was two-threaded. On 27 of July the physical parameters – fruit shape index (length/diameter), firmness (kg cm-2), water-soluble dry matter content (Brix%) and weight of the berries (g) – were evaluated. On 15 of August the rheological parameters were examined – the force needed to tear the skin – bioyield point (g) and flesh firmness (g).
The fruit shape index was oval (between 1.19 and 1.24) for all the examined genotypes. The firmness was between 0.92 (UG1122713 F1) and 1.05(Prestomech F1) kg cm-2, which compliance the needs of the industry. The water-soluble dry matter content was suitable, with a value between 4.49 (Prestomech F1) and 4.65 (UG1122713 F1) Brix%. The weight of the berries was between 45.94 (UG989 F1) and 49.37 (Prestomech F1) g per piece.
The bioyield point was between 76.00 (UG1122713 F1) and 85.16 (UG989 F1) g. The flesh firmness was between 33.68 (UG1122713 F1) and 42.81 (UG989 F1) g.
Finally, we can conclude based on the obtained data that the UG989 F1 hybrid was the most proper for the applied cultivation conditions. This genotype can be recommended for the farmers even in extreme weather conditions.

Examination of resistance against Aeromonas hydrophila infection on genetically different common carp variants (preliminary results)
7-11Views:83Septicemia disease caused by the bacterium Aeromonas hydrophila is a major problem for fish farmers around the world. In our experiment resistance to the disease was investigated on carp variants with diferent genetical backgrounds. 96 different genetic variants(„families”) were created by crossing various individuals of 4 carp strains (2 wild and 2 cultured ones). Families were reared until reaching the size of 10 gramms and 100 fish of each families were marked with an individual electronic identifier. Marked fish were divided into 5 groups. Fish from one group were infected with A. hydrophila and mortality were registered during 2 weeks. Based on mortality data, the most resistant and most susceptible families will be selected using population genetics methods.

Use of Forecasting Methods in Price Analyses
240-247Views:40The cost of products changes not only seasonally in relation to time, but also follows a hectic motion. It is necessary for the farmers to calculate in advance the size of the future income, which is one of the basic conditions of the economical production. Many authors have examined the change of the prices but since the tendency of the change of the prices can be only rarely observed purely by itself, therefore it is difficult to separate it. During my research I examined how the monthly prices of corn and the monthly buying prices of pigs for slaughter have changed since 1991 and how much their future value will be. I examined how much is the α factor wich gives the minimal residual variation in case of the Brownian dual exponential smoothing and the corrected dual exponential smoothing and how will the future (2002) prices, which were in this way calculated, change compared to their real market prices.
