Investigation of harvest index influencing agrotechnical and botanical factors in hairy vetch (Vicia villosa Roth.)
123-128Views:136The biggest problem of Hungarian crop farming is mass production and the simple crop rotation based on cereals. There was a decrease in sowing area of protein crops which raises crucial issues in crop rotation and land use. Therefore, growing papilionaceous plants, which are now considered to be alternative plants, should be taken under close examination. Hairy vetch (Vicia villosa Roth.) belongs to the family of papilionaceous plants and it can be grown in light weak soils.
In Hungary, hairy vetch was used as green forage at first, but it later became a green manure plant. Nowadays, it is used as a cover crop and its sowing seed has a good export market. In low fertile soils it is able to produce a big amount of green yield (25–40 t ha-1) even in spring while its seed yield could be 0.4–0.5 t ha-1 at farm level. In addition to its morphological characteristics hairy vetch is grown mainly with a supporting plant, i.e. triticale in many cases.
Our purpose was to test the harvest index and its agrotechnical and botanical factors of hairy vetch in different cropping systems.

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. -
Research on rheological characteristics of winter wheat varieties
266-272Views:140The gluten examination test is dominant in Hungary, comparing it to the qualification system of other countries. The determination of alveographic parameters is a basic criterion of winter wheat specifications in some western and southern European countries.
In the Hungarian and foreign winter wheat qualification systems, in the standards, there is no limit for extensographical parameters. Customers dictate the limits and make their claims as to the specifications.
We analyzed the alveographic and extensographical parameters of 19 winter wheat varieties grown by the Cereal Research Non-Profit Company in Hungary, and we made a comparison between the results in the challenges of the European Union expectations.
Examining the information of alveographic and extensographical values, we found that the experimental varieties provide high base to flour types suitable for baking bread and baker’s ware. The GK Élet, GK Petur, GK Memento, GK Csillag, GK Kapos and GK Marcel varieties can meet the market of paste flour needs, too.
In the variety series, the GK Kalász represents the highest values and the GK Garaboly shows the lowest parameters regarding the alveographic W and the resistance to extension.
On the basis of relation, we can establish that we can estimate the following little known and used quality indexes: the extensographical resistance to extension with extensographical energy and the alveographic W value, the extensographical energy with the alveographic W value and the alveographic P and L values with the other alveographic parameters. -
The influence of fraction size on the chemical composition of winter wheat flour
123-126Views:90Wheat is one of the most important cereals in the world and the bread made of its flour belongs to the everyday life of human mankind.
The Hungarian standard relating to the laboratory production of wheat flour (MSZ 6367/9-1989) does not mention the type of laboratory mill used for milling, and it only builds up some general criteria, such as: the laboratory mill should be provided with four differently nicked barrels, a sieve with appropriate hole sizes, and also with the separated collections of the pilot flour and the bran. Our study was started at this point and the answers for the following questions were aimed to be found: do the flour patterns studied and produced with different sieving techniques,
widely used in laboratory mills of the same wheat pattern show any alterations after the impact of the formula production as regards chemical constitutions. Various flours of the wheat pattern sieved with different particle sizes were studied in this experiment.
In producing this pattern we used FQC109 type of mill. There were 5 different corn sizes of 250-200; 200-160; 160-125; 125-100; <100 μms used in the partition of the fractions. The results this research confirm that the quality of wheat flour can be modified by different methods of pattern production. -
Development alternatives of rural economy
187-191Views:101Environmental, natural, social and economic processes undergoing both in Europe and in the world predict such a 21st century that is characterised by increasing resource-crisis from both economic and ecological aspects. Therefore, it is very important for Hungary to see what happens to its natural resources, epecially to its agricultural land, water reserves as well as the biodiversity of the local unique flora and fauna. One of the most significant issues of the rural areas of Hungary is whether we can preserve the natural habitats and the various biodiversity of the related species, the favourable biological background of agriculture. In addition, whether we are able to provide high quality food for the country as well as for the broader reagion, whether we are able to produce energy from the resources available as well as to provide sufficient opportunities for the population to live and work. These can be considered as the most significant issuesof the coming decades which determine the strategy of the Hungarian rural economies in long term.

Estimation of genetic parameters and genotype effects for crossing constructions of Hungarian Pigs
57-60Views:139Authors estimated the genetic parameters and genotype effects of average daily gain (ADG), age (AGE) and lean meat percentage (LMP) using the field test data of Pietrain (Pi), Duroc (Du), Hampshire (Ha) pigs and their crosses. Data was collected by the Agricultural Agency of Administration between 1998 and 2010 originating from 68 herds. Datasets of the different crossing combinations (Pi, Du, Pi × Du; Pi, Ha Pi × Ha) were evaluated separately using bivariate animal models. The estimated heritabilities were moderately low: 0.24–0.29, 0.22–0.26 and 0.18–0.19 for average daily gain (ADG), age (AGE) and lean meat percentage (LMP), respectively. The estimated genetic correlation coefficients were negligible: -0.07–0.01 (ADG-LMP), -0.01–0.04 (AGE-LMP). The Pi × Ha and Pi × Du crosses showed 6.76% and 4.96%; 6.74% and 4,17% and 0.08% and 0.44% heterosis for ADG, AGE and LMP, respectively. Among the environmental factors the herd effects were substantial: 41.17%, 53.67% and 14.16% for AGD, AGE and LMP, respectively. The smallest environmental influences were found for LMP.

Effect of cadmium and zinc contamination on the population dynamics of soil microorgani
73-77Views:111Changes in the population dynamics of microorganisms in a soil artificially contaminated with various doses of cadmium and zinc was examined from a quantitative point of view, under laboratory circumstances. The research was based on a chernozem soil originating from the area of a long-term microelement contamination model experiment (Nagyhörcsökpuszta, Hungary), which was carried out during 1991 in the Experimental Site of the Institute of Soil Science and Agricultural Chemistry, Centre for Agricultural Researche Hungarian Academy of Sciences, Budapest, Hungary. According to the amount of bacteria, microscopic fungi and nitrifying bacteria, it can be stated that the effect of contamination can be observed even in the perspective of nearly two decades. In more cases significant changes in the number of soil bacteria and microscopic fungi could be observed, and the nitrification activity increased in case of both microelements. Therefore the further research of changes in microbial activity of these soils can provide novel scientific results.

Micropropagation of Leuce-poplar clones and its role in selection breeding
43-48Views:162Leuce-poplars (mostly white poplar and its natural hybrid grey poplar) are native tree species trough Hungary. They are covering more than 4.0 per cent of the Hungarian forested area (77 000 ha). The white (grey) poplars play a significant role in the forestation under sandy soil site conditions as well as they are of importance from nature conservation point of view as well.Long-term selection breeding work is going on at the National Agricultural Research and Innovation Centre Forest Research Institute (NARIC FRI), involving selection of fast-growing Leuce-poplar clones under dry site conditions.Micropropagation technology is relatively quickly spreading in forestry. In vitro multiplication of trees is applied mainly in fruit growing in Hungary, in case of forestry it is used mainly for selection breeding.This paper presents a short overview on the micropropagation trials with different Leuce-poplar clones and the early evaluation of the seedlings growing of the micropropagated clones/varieties. -
Analysis of Economic Efficiency of Energy Wood Plantations
53-60Views:77After the EU-accession we should have a definite idea about what kind of production structure and land use should Hungary obtain to meet the conditions undertaken in the different governmental decisions. In the course of Hungarian land use, significant changes have taken place in the last eighty years. Further changes are influenced by the fact that according to various decisions, legislative provisions and ideas in a short time the energy orchards’ domiciliation could start in large. For this, financial support can be required from EU-sources. As for the woody energy plants, subsidies can be required for the domiciliation and as for herbaceous plants grants can be required for growing. As far as the latter is concerned, the subsidy will be around 26-27 thousand Ft/hectares according to the plans. However, the cultivation method does not have to be changed to
switch from plow-land to energy plants. The question is if the produced commodity will be received by power plants and if it ensures appropriate income for the farmer. In my research I wanted to find from the given woody energy plants which are those that are the most profitable. -
Study on distribution and relative abundance of click beetle pests (Elateridae: Agriotes sp.) in Hungarian maize fields
107-113Views:95Click beetle pests (Elateridae: Agriotes sp.) of 24 sites in different regions of Hungary were studied in 2011. A. brevis, A. sputator, A.
obscurus, A. lineatus, A. rufipalpis and A. ustulatus were sampled by pheromone traps in maize fields. During the study 65895 beetles were
caught. A. ustulatus and A. sputator were the most abundant species. Beyond that 23 additional species were trapped so the total number of sampled species was 29. The distribution of the six studied species was uneven. In east Hungary A. ustulatus were the most abundant, while
in the Transdanubia A. sputator was dominant in the most studied sites. A. obscurus occurred mostly in Transdanubia (western Hungary), and it occurred only in one site of eastern Hungary.
The abundance of one or simultaneously two species reached the threshold of significant damage in 14 sites. Additionally there were three sites where the total abundance of the two most dominant species reached the threshold. There were only six sites where we should not expect significant damage. In this reason we have to monitor the populations of these pests and if it is necessary we have to take actions against them. -
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.

Review on the fatty acid profile and free fatty acid of common carp (Cyprinus carpio)
99-105Views:113Carp or ponty in Hungarian, is considered commercial freshwater fish, which is an adaptable species in both wild and cultured conditions. Carp has high nutritional value content, favorable taste, it is rich in protein, and low in saturated fat. The nutritional content in fish is composed of many chemical constituents and influenced by many factors. One of the components that its content may be different due to internal and external factors is fatty acids, which may vary depending on endogenous and exogenous factors. The endogenous or internal factors include the genetic, size, sexual maturity, and life cycle phase. While microclimate, water quality, quality of food or diet habit, and the amount of available food or starvation are considered as exogenous or environmental factors. Freshwater fish has the ability to convert essential fatty acid into long chain polyunsaturated fatty acid like AA, EPA, and DHA. Most results showed that palmitic acid and oleic acid were the dominant SFA and MUFA in carp both for wild and farmed carp in all seasons. The PUFA for wild carp was mainly dominated by DHA, while on farmed carp by LA. It confirmed that high LA content in farmed carp was related to the diet habit. The amount of lipid and FA were changed in line with the season. Even the statistical analysis showed no significant difference, but some studies showed a contrasting result. Moreover, most obtained results acknowledged that FA tends to decrease during the spawning period. The amount and composition of FA were affected by the total lipid content. The lipid must be broken down into simpler compounds such as FA or FFA for the metabolism of fish. The result of metabolism then transported into the utilising tissue and used as energy.

Phosphorus (from Different Phosphorus Sources) Utilisation in Piglets, and the Effect of the Addition of Phytase into the Feedstuff
30-36Views:71The experiments were carried out in a 2x2 factorial treatments with three replicates, and were completed with 32P phosphorus metabolism measurement. Hungarian Large White x Dutch Landrace growing pigs with 15–18 kg starting live weight were involved in the experiment.
The experimental scheme was the following:
Diet consisted of maize and extracted soybean meal. Both components have high phytase content and low phytase activity. 1/a animals received their P-supply according to their needs and 1/b animals got 10% less than their actual P-need in the first part of the experiment.
In the second part of the experiment both groups (2/a, 2/b) received identical P-supply and 500FTU/kg P supplementation. Apart from P- and phytase-supplementation, the piglets’ diet was identical.
Total P digestibility was 52% without phytase supplementation, which increases by 4% when P was added according to need and by 12% increase of decreased P-supply. Digestibility of nutrients somewhat increased as effect of phytase supplementation. According to the results of 32P experiments, inorganic P digestibility of MCP was 82–90.8%, which decreases to 73.4–87.2% in case of phytase supplementation.
Parallel with tendency, native P digestibility of the diet was 31.5–32.2%, which increased to 42.5–54.5% in the case of phytase supplementation.
Results support the that inorganic P input can be decreased by phytase supplementation and as a consequence P output, the concept and environmental pollution can at the some time be decreased. -
On the Knowledge of University Students About the Strategies of National Sustainable Development
232-240Views:94The definition of sustainable development has a past which spans two decades. Today it is evident that the three pillars of sustainable development – environment, economy and society – have a strong correspondence and equally effect on every people. The UN’s Environment and Development Conference in 1992 declared the requirement in the document of Objectives for the XXI. century, that governments should prepare national sustainable development strategies. The World Conference of Sustainable Development in August 2002 made a stronger decision: „the states should make immediate steps forward … defining and preparing their national sustainable development, and for the purpose to start its realization until 2005”. Most of the countries fulfilled these requirements, and the Hungarian government promises to prepare its national strategy by the end of 2004.
The aim of my study is to survey the knowledge of university students about the above mentioned process and generally about the topic of sustainable development. The selection of the target group is justified by the importance of young intelligentsia in the future. In order to examine their knowledge, I prepared a questionnaire and from the emerging primary data, my conclusion and statements have been deducted by a processing-analysing course, on the bases of which I made my suggestions. -
Effects of Cropping Year and Artificial Fertilization on Alveographic Quality of GK Öthalom Winter Wheat Variety
126-133Views:98Qualification of winter wheat became more complex for Hungary, after the expansion of the EU. Use of Chopin alveograph is a general method in Western- and Southern Europe. This method is not traditional in Hungary, so determination of alveographic properties of Hungarian winter wheat varieties is very important. Artificial fertilization is one very important component of applied agricultural engineering, which effects winter wheat quality. The another factor is the weather or rather the cropping year, which effects winter wheat quality too. We examined both of them and the alveographic quality of GK Öthalom winter wheat variety between 1996 and 2003.
We found that cropping year has significant effect on the alveographic quality of GK Öthalom winter wheat variety on each treatment of artificial fertilization. We found no connection between quantities of precipitations of vegetation periods and the W values of GK Öthalom.
We found a strong connection in 1999 and 2003 as well as a very strong connection in 1996, 1997 and 2002, between the increase of fertilizer dose and W values of GK Öthalom. Treatments of artificial fertilization had a significant effect to W values of GK Öthalom in 2001 and 2002. The differences between the two methods are because of large standard deviation of the results. -
Food Safety in EU Higher Education
188-197Views:77Under the aegis of the Lisbon Strategy, special attention is paid to education and areas left untouched by the European integration process. Human capital and research inputs were identified as major driving forces for long-term development. The European Union is keen on meeting its target of boosting research spending to 3% of GDP by 2010. In order to contribute towards his goal, the European Commission has set aside an amount
which is double the budget of the 7th Framework Programme. Accordingly, preferences were given to research and development projects encouraging competitiveness in the food industry and other initiatives, such as the European Technology Platforms. Major obstacles to innovation in Hungary are: lack of funds, weakness of research network, poor structural relations. Better utilization of our comparative advantages should be targeted in order to have the Hungarian food industry become a driving force sector. This is to be promoted by the newly transformed food
engineer training (as a result of the Bologna Declaration) which can adapt better to the changing requirements of the labour market. Food science and related research could become determining factors for the food economy by setting up accredited training systems and enhancing food safety education and training in Hungary. -
The role of Local wine administration bodies in creating social and cultural capital and in the preservation of local identity
181-191Views:74the target for the European Union to make Europe the most competitive and dynamic knowledge-based economy in the world. In this process, the education and training are of great importance for the member states. The restructuring of higher education, the modernization of the universities cannot be achieved without new financial resources. They should be ensured by increasing contribution of the private sector. However it is not enough to invest sufficient funds in the educational and training system, they must be expended efficiently. The free higher education itself does
not necessarily guarantee the equal access and maximal participation. The quality of higher education and equal opportunity can be improved, if the rising funds are expended on infrastructure development and creating an efficiently working student support system.
Quality, equal opportunity, efficiency – they are the most important views for the decision-makers in the higher education reform. In my paper, I would like to interpret definitions relating to higher education and in this way I attempt to evaluate the financing systems of the Hungarian higher education formed since the change of the regime, with special regards to the normative financial system combined with the payment of tuition fees. For classification, it is necessary to present the different basic financial models. Furthermore, on the basis of the above criteria, I try to make recommendations on how to improve the present financial model in order to achieve the Lisbon objectives.
The topic is important in our days, because tuition fees will be introduced in Hungary from 2008. The problem is very complex, although the analysts in most cases tend to approach the topic with prejudice, depending on their financial and political interests. My analysis may contribute to discernment in the tangle of the pros and cons. -
Examination of the American grapevine leafhopper (Scaphoideus titanus Ball) in Debrecen and Micske (Misca, West Romania)
77-81Views:148Grapevine flavescence dorée (FD) was detected first in Hungary in 2013 in Zala County (South-West-Hungary). The disease is a serious danger for grapevine growing and grapevine propagating production. In 2014, the pathogen has been found in several new places in Hungary, viz. in Vas and Fejér Counties, and it was also detected in the former location in Zala County. The american grapevine leafhopper (Scaphoideus titanus) is the main vector of the disease. This pest was detected first in Hungary in 2006 and then it has spread all over the country. Since we have not detailed distribution data of this pest in surroundings of Debrecen, therefore we made observations in this region in 2014. The presence of the pest was confirmed by yellow sticky cards in two locations in Debrecen and another site in West Romania near to Hungarian border. We found that S. titanus is present in each sampled sites that cause serious potential danger for the appearance and spread of Grapevine flavescence dorée (FD) in this region.

Comparison study of student with special educational need in elementary school
71-76Views:148The 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. -
Examination of the interval between litters (IBL) of different genotype HLW sows using survival analysis
13-17Views:177In this study our aim was to find out if there is a difference between the genotypes determined for the previously identified mutations of seven genes of the Hungarian Large White in terms of the time spent in production. We identified the previously determined alleles of the seven genes (BF, EGF, ESR, FSHβ, H2AFZ, LEP, PRLR) related to proliferation that were and performed the survival analysis between breeds indicating the risk of culling and the time spent in production on the given farm. Based on the results of survival analysis by Log-rank test, Breslow (Generalized Wilcoxon) and Tarone-Ware test we concluded that they indicated a significant difference in case of the genes BF (Breslow and Tarone-Ware tests) the EGF (Log-rank and Tarone-Ware tests) and ESR (Log rank test) based on which the curves of the survival of the certain genes varied form one another significantly.

Comparison of crop production in Hungary and Tanzania: climate and land use effects on production trends of selected crops in a 50-year period (1968-2019)
141-149Views:141A comparison of selected crop production for Hungary and Tanzania is presented. The roles of climate, land use and productivities of crops vary significantly in the two countries. Climate impacts the distribution of crops in Tanzania more than in Hungary as Tanzania’s climate is diverse with hot, humid, semi-arid areas, high rainfall lake regions, and temperate highlands. In contrast, the Hungarian climate is temperate and uniform across the country. Land use changes significantly in Tanzania than in Hungary. Tanzania indicates a reduction in forest land and expanding agricultural land associated mainly with the variation in crop productivities and population growth. To maintain sustainable crop production, increasing crop productivity is of paramount focus to meet the requirements of the growing population.

Examination of different fungicides against Macrophomina phaseolina in laboratory conditions
65-69Views:145In Hungary, sunflower is the third most important arable crop, which has a lot of pathogenic fungi. One of these fungi is the Macrophomina phaseolina, which is a well-known fungus in all over the world, since this pathogen has more than 700 host plants. In Hungary, several host plants can be found as well. The M. phaseolina produces microsclerotia, which can survive in the soil and residues for almost 10 years. For now, there is no efficient treatment against this pathogen because of this fungus, since it is extremely resistant and cannot be destroyed easily. The only effective treatment against the fungus is genetic defence. In this study, three different fungicides were tested in vitro against the fungus. The Mirage (prochloraz) seemed to be the most effective fungicide as it completely arrested the hyphal growth. In contrast, the Amistar Xtra (azoxystrobin and ciprochonazol) has only a minor effect on the growth of M. phaseolina. Thirdly, the Retengo (pyrachlostrobin) arrested the hyhpal growth of the fungus with 71% at 100 ppm, in other words, the use of this fungicide seems promising.

Study on the Work Organization at Dairy Farms
293-296Views:56Joining the European Union Hungarian producers have advantages but they need to solve some problems too. Only those producers can compete who will be able to produce extra quality milk. However the circumstances of milk production are not up to the task.
The author examined the work organization of 7 dairy farms in Hajdú-Bihar County. Data were collected about the situation of farms, equipment of barns, objets of production, work force, qualification of workers, and productivity of work. He examined the applied motivation methods at farms. He concluded that as the number of cows per farm increases work productivity increases too. From the examination it appeared that family farms applied different motivation system from bigger producer organizations. The author put forward proposals for motivation possibilities to improve milk quality, atmosphere, and general feeling of workers. -
Comparative Senses-based Investigation of Traditional and Modern Apple Cultivars
70-74Views:66Apple consumption has significantly decreased over the last 10-15 years in Hungary. While consumption of fresh apple was 25 kg/person/year before the change of regime, today it hardly exceeds 10 kg according to careful estimations. In spite of the fact that the former dull cultivar structure (Jonathan, Starking, Golden Delicious) has widened with numerous new cultivars, apple consumption in Hungary has not increased. Unfortunately, customers do not or scarcely know most of these new cultivars.
In a survey conducted among the students of five Hungarian universities, we gathered information about comsumer opinion of both and older cultivars.
Numerous questonnaires – 592 – were filled out on 8 cultivars (Jonagold, Novajo, Topaz, Golden Reinders, Idared, Pinova, Braeburn, Jonathan, Starking) about the qualitiy parameters that determine the value for consumption. The results clearly show that besides the old cultivars, such cultivars are preferred that are known worldwide, such as Jonagold, or Golden (free of russetting) or the resistant Topaz.
Promotion of these cultivars and creating the possibility of their supply can help to increase a fresh apple consumption. -
Comparison of Reproductive Performance of the Roe Deer (Capreolus capreolus, L.) Among Different Regions
41-46Views:84The potential and actual number of offspring of roe deer and the difference between these figures (prenatal and postnatal loss) significantly vary in each population yearly. The objective of this study is to examine the potential and actual number of offspring, the number of losses, and to find a link between the most important biological characteristics of does (body weight – BW, condition – KFI) and the number of raised offspring on four territories on the Great Hungarian Plain.
Where the number of corpora lutea (CL) is the highest, there the losses are the highest as well, and the number of raised offspring is the lowest (region I.). Here, the rearing loss is double that of the weakest territory (region IV.). Rearing losses can be associated with the fenotype of does (BW, KFI) but environmental factors also have determinative importance. Where the number of twin-calving does was the highest, I found four times more does without a fawn than where the number of twin-calving does was the lowest. The nursing success was the best (the losses were lowest) in the region where the potential offspring (number of CL) was also the lowest, but the coverage of the habitat and the proportion of forests were largest. The food supply for the animals in autumn and winter are not enough, the structure of the habitat has to be improved as well, so that it might become adequate for game protection in extreme weather conditions.
The results have to be considered as preliminary ones. It is essential to continue and extend the research to increase the reliability of the results.
