Effect of facility location on haulage efficiency
204-209Views:76In the 21st century, every economic sector must use the chances of evolution, technical and technological acquisitions, due to the level of competitiveness on the market. Such a sector as agriculture, where technology and the ideology of production are changing and adapting very slow to global expectations, by taking maximum advantage of opportunities, is a more central question. The greatest problems of Hungarian agriculture’s competitiveness are that this sector is very weak in capital and production costs make producers uncompetitive on the market. We can remedy this situation by using sources logically, purposefully and system approached. Logistics can provide the most useful assistance in such efforts.
In agricultural logistics, there is a great deal of uncovered territory. The aim is to transplant methods that are working correctly in other sectors into the agricultural sector, while maintaining development. One of the most important areas is transport logistics and material movement. Methods of analyzing and planning transportation and material movement found in professional literature do not take into account the specific needs of agricultural production. My aim is to examine the effect of facility location in the running of an enterprise. Through the results, I make suggestions for modifying the currently used logistic method and suggest further methods of examination. The effect of agro-specific needs must be examined in carrying out innovations and making logistical planning methods reliable. -
Aflatoxin production on agricultural products
67-71Views:139Aflatoxins due to their toxicity pose significant economic and human health threat; therefore, it is important to avoid this type of contamination in agricultural products. Until now significant aflatoxin contamination occurred mainly in foods of tropical and subtropical origin because the optimal growth of the producer Aspergillus species is between 32–38 ºC. Nowadays the aflatoxin contamination is becoming higher threat in Hungary, due to the imported products, the rising average temperature and the climatic changes. There is a significant knowledge on the genetic and environmental effectors of the aflatoxin production; however, it is remained a great problem to control mold contamination and toxin production in farming and stock-raising. Here we attempted to summarize the knowledge on aflatoxin production and attempts of the elimination.

Testing the antimicrobial activity of essential oils
71-74Views:131The vapor phase of some essential oils proved to have antimicrobial activity. Utilization of the vapor phase of Eos is presently understood as one of the possible alternatives to synthetic food preservatives which could be used in the future. However, testing the vapor phase of EOs against microorganisms causing food-borne diseases (e.g. Salmonella enteritidis or Staphylococcus aureus) or food spoilage is relatively new. Consequently, due to the large number of known EOs, research on their antimicrobial activity is still largely in the phase of in vitro rather than in vivo testing. Moreover, no standard and reliable method for fast screening of a wide range of samples exists. Thus, the aim of this study is to show results concerning tests of the antimicrobial activity of EOs against S. enteritidis or S. aureus, which were conducted by two modifications of the disc volatilization method we developed. The lately developed method has the potential to become widely used for fast screening of EO antimicrobial activity in the vapor phase.

The role of animal breeding with special regard to native pigs of food supply and rural development in Laos
149-154Views:243The present paper explored the influence of breeding native pigs on livelihood conditions and the contribution of native pigs to the rural development and rural poverty reduction in the rural areas of Lao PDR. Pig production plays an important role in meat supply for both urban and rural areas of Laos. It is clear that most of the pig products in the country come from smallholder pig farms, and more than 90 percent of those products are the native pigs mostly raised by farmers in remote areas. In general, livestock production distributed between 15–18 percent to GDP, while most of animal production still remains as the traditional methods. Rural development is always the first priority of the Laos government since its independence in 1975, however, the poverty rate in rural areas remained high at 23% in 2018. It might block the development goal of the government which will lead the country out of the least development status by 2020. The food security and malnutrition in the rural or mountainous areas are considered as the majority issue that both government and several international organizations have been thriving hard to overcome, which researchers showed that more than 45% of children under 5 years of age were stunted, and 28% of them were underweight. Inspired of more than 50 % of the households in the rural areas of Laos reported they consumed chicken and pork at least one day a week. While native pigs play an important role on meat supply, it also constituted around 9–14 % of annual income of the households in rural areas. Therefore, the increase the production of pigs and poultry is one option to promote the meat supply to households in the rural areas of Laos. This paper will be a pathway to guide and identify for the final decision to what experiment will be implemented on Lao native pig in Laos (2021–2023) to complete the comparative study on reproductive physiology and reproductive management methods of Hungarian and Lao Indigenous pig breed. Which found it still needs further afford to research and improve more about native pig performance for all areas of productive and quality management.

The evaluation of body condition scoring of Holstein-Friesian cows
57-61Views:105We carried out the examinations on a farm of 500 cows where We examined the body condition of the stock every month. We recorded the body condition data together with the milk production and calving data. We analysed the daily milk production as well as the body condition. During the examinations we sought an answer how the body condition and the production level change during the lactation period.

Baking quality of winter wheat (Triticum aestivum L.) in the long-term experiments on chernozem soil
152-156Views:69Agriculture has traditionally an important role in Hungarian economy and rural development. About 75 % of Hungary’s total territory
is under agricultural land use. Because of ecological conditions and production traditions cereals (wheat, maize etc) have the greatest
importance in Hungarian crop production. In the 1980’s the country-average yields of wheat were about 5,0-5,5 t ha-1 („industrial-like”
crop production-model). In the 1990’s the yields of wheat dropped to 4,0 t ha-1 because of low input-using and wide application of the issues
of environmental protection and sustainability. Winter wheat production for quality has a decisive role in certain regions of Hungary
(eastern and middle-parts).
The quality of wheat is complex and different. Three major growing factor groups determine the quality of winter wheat: genotype,
agroecological conditions and agrotechnical factors. In wheat production for quality the selection of the variety is the most important
element. Our long-term experiments proved that the quality traits of a variety means the highest (maximum) limit of quality which could not
be exceeded in fact. During the vegetation period of wheat the different ecological and agrotechnical factors could help or on the contrary
could demage the quality parameters of wheat.
The agrotechnical factors determining the baking quality of wheat can be divided into two groups: the first group means the factors with
direct effects on quality (fertilization, irrigation, harvest); the second group contains the elements with indirect effects on quality (crop
rotation, tillage, planting, crop protection).
Appropriate fertilization could help to manifest the maximum of quality parameters of a wheat genotype and could reduce the qualityfluctuation
in unfavourable ecological and agrotechnical conditions. -
Utilization of the field experiment results of University of Debrecen in the development of maize-based bio-ethanol production
55-57Views:131Maize is currently the single raw material of bio-ethanol production in Hungary. The aim of our examinations is the observation of yield and
nutritional characteristics of commercial maize hybrids in Hungary from the aspect of efficient bio-ethanol production. We set up a
randomized block field trial. We determined the starch content and starch yield (t ha-1) of the 51 maize hybrids involved in the field trial.
In laboratory conditions, we examined the amylose and amylopectin ratio and the amount of resistant starch of the selected 20 maize hybrids.
According to our results, there is a significant difference between the starch yield the amylose component of the starch content and resistant starch of the examined maize hybrids. Our studies reveal that maize as a raw material must be selected based on the cultivation objectives. If the objective is bio-ethanol production, detailed knowledge of starch content is necessary. There is a significant difference among commercial maize hybrids in Hungary in terms of characteristics determining the producible amount of bio-ethanol. -
Supplementary botanical examinations for modelling the grass production of the great pasture of Hajdúbagos
17-21Views:59Our botanical survey at the great pasture of Hajdúbagos is a part of a broad research that aims to predict the production of the grass at the given area. As the mentioned pasture is a nature conservation area, the usage of artificial fertilizers or other classic grassland management methods in its handling are prohibited. Thus grazing is an important tool for the management of this area, however the not suitably regulated grazing order and the poorly calculated carrying capacity cause serious problems at some parts of the pasture. The prediction of the grass yield is essential to
avoid both over- and both under-grazing and for determining the optimal number of the grazing animal stock and the grazing method, thus the most suitable management strategy.
The potential grass yield is easily calculable with a computer model that will be established as a basis for determining the grass production. For the sake of getting an accurate view of the plant associations of the pasture, we created examination quadrates and determined all plant species found in the quadrates. After plant determination, we compiled a coenological table in which we marked besides the scientific name and families, the life forms of each species that refer to the structure, morphology and thus the adaptability of plants to their environment. We determined the
TWR, so the thermoclimate, water and soil reaction values, the nature conservation values, as well as the covering values of each plant species (DB), and the total coverage of the examination quadrates (B%).
According to the covering values, grasses proved to be characteristic plants at the examined pasture, thus we need to consider them influential in calculating the animal carrying capacity and with the rest of the information, we need to supply the model.
The life forms and TWR indicators, all together with the nature conservation values provide further important data to the development of the management suggestion of the protected pasture. By examining these values to different parts of the area, we could get an exact view on the measure of the degradation effects. This promotes the determination of grazing methods and the forming of the boundaries of certain pasture sections, to avoid those harmful anthropogenic effects that seriously endanger this extensive sandy pasture. -
Impact of ammonium nitrate and Microbion UNC bacterial fertilizer on dry matter accumulation of ryegrass (Lolium perenne L.)
35-39Views:80Pot experiment was performed to investigate the effects of increasing NH4NO3 doses with or without Microbion UNC bacterial fertilizer
application on dry matter production of ryegrass (Lolium perenne L.). Experiment was set up on calcareous chernozem soil of Debrecen-Látókép and on humus sandy soil of Őrbottyán. The bi-factorial trials were arranged in a randomized complete block design with four replications. Grass was cut three times. Dry matter production was determined and the sum of biomass of cuts was calculated as cumulated dry weights. Analysis of variance was carried out on the data in order to provide a statistical comparison between the treatment means. The least significant difference (LSD5%) test was used to detect differences between means. On the basis of our results it can be concluded, that the dry weights of ryegrass cultivated on chernozem soil were higher than on sandy soil. With increasing nitrogen supply the dry matter production of grass significantly increased in both types of soils. In case of sandy soil the increasing effect was more expressed, but dry weights of this soil never reached the appropriate values of chernozem soil. Application of Microbion UNC had positive effect on dry matter production of ryegrass grown on both two types of soils but the effect was more expressed on chernozem soil. Finally it can be concluded that the increasing effect of NH4NO3 on biomass weights was more expressed in both types of soils, the biofertilizer application also increased the dry weights of plant in a small degree. -
Comparison of apricot cultivars for suitability for organic growing
63-65Views:60Nowadays, important task is using more widely the environmentally friendly production technologies. There are considerable differences
among technologies using reduced spray programs (integrated and organic) in plant protection and plant nutrition.
In this case integrated production has a better position as roles for organic production more strict and due to this fruits has an obvious
temporal and permanent reduction in tree conditions. Fitotechnical elements and renewal and regeneration of cultivars are important
factors for offseting or delaying of condition weakening.
In this study, 5 apricot cultivars (not pruned for 8 years) were compared in their characteristics (assessment of inactive, semi-active and
active plant parts).
Our study showed that there were 50-70% differences among observed characteristics. Our study confirmed those cultivars which are
suitable for organic production and which one more resistant to condition weakening and which one able to tolerate negative technological
effects. -
Economic Aspects of Winter Wheat and Sunflower Production Under Organic Farming Methods
256-261Views:84On the basis of data from selected organic crop producing farms around Hortobagy and a significant conventional agricultural enterprise, the efficiency calculation of two important crops, winter wheat and sunflower were compared to each other, according to the organic and the conventional farming methods. The analysis was carried out on the basis of data of the year 2002, helped by the calculation and the comparison of the efficiency indexes. According to the results, the organic winter wheat was more highly profitable in 2002 than the conventional one, and this is because the price ratio of the two was quite high, however the yields and the production costs per hectare were almost on the same level. Considering the sunflower, organic farming was less productive than the conventional one in 2002, as the average yield in the examined organic farms was significantly lower than under the conventional farming method, and this was not compensated by the extra price for the organic crop product.

Estimation of Inheritabilities from Holstein-Friesian Test Day Data in Hungary
23-25Views:106Recently, test day models (TDM) began to be increasingly used for the genetic evaluation of dairy cattle. The main advantage of the TDM compared with the 305 days lactation yield models is that more effects can be used in the evaluation. Therefore, the TDM is more accurate than the lactation models. The main disadvantage is the increased computational requirement, but this can be offset by improvements in computer capabilities.
The topic of this paper is the use of a fix regression test day model to estimate the inheritabilities of test day data from Hungarian Holstein-Friesian dairy cattle. The inheritability was 0.26 for milk production, 0.2 for fat production, 0.24 for protein production and 0.06 for the somatic cell count. -
Yield and sward composition responses of a native grassland to compost application
35-38Views:170A major part of the animal products are based on the grasslands, due to the fact that the grassland ecosystems can be found all over the globe. In places where economical and successful crop production cannot be realized, the grassland based animal husbandry can be an efficient way of food production. In addition these ecosystems have an important role in carbon sequestration, and with their rich flora – and the fauna connected to it – in conservation of biodiversity. The protection of nature, and the sustainable agriculture is getting more and more attention in the European Union, but looking at the consumers’ needs, the production of healthy food cannot be neglected either. Because of these facts, the effects of two specific composts - which are officially authorized in organic farming, in Agri-environment Schemes and Natura 2000 programs – on grass yields and sward compositions were investigated in a field trial. The investigation took place in Hungary, on a natural grassland based on solonetz soil. The first type of compost was a natural one (N) without any additional material and the other one was enriched in phosphorus (E). Both was produced by the research institute, made of sheep manure. Three rates of compost (10 t ha-1, 20 t ha-1,30 t ha-1) were tested on 3 m×10 m experimental plots. Every treatments had four replications and both type of compost had four-four control plots too, this way 32 experimental plots were included in the investigations. The yield of the pasture was harvested two-times (in May and in September) and before cutting the plots measurements on botanical compositions were made. Samples for laboratory analysis were also taken. Dry matter yield and crude protein content was measured in laboratory and with the received data the yield per unit area was calculated. Based on the research results we can say that the application of compost in any dose inflicts higher dry material and crude protein yield. The changes were partly due to some positive changes in sward composition, because of the better nutrient conditions. The research results indicate, that use of organic compost can be an efficient way to increase grass yields in a sustainable way.

Characteristics of Land Use and Plant Production in Transcarpathia
290-294Views:35The character of plant cultivation and animal husbandry in different parts of Transcarpathia, are mostly determined by the location of a given region. Usually, four zones are delineated: 1. lowlands; 2. foothills and volcanic remains zone; 3. inter-mountainous subsidence and deep valley; 4. mountain zone.
In county this zone divides quite visibly. By studying the soil, climatic conditions and plants, it is not difficult to see that the vertical zones play a major role in their characteristics and formations. If we go from lower to higher elevations, we can observe the qualitative difference in the environment and, of course, in the character of agriculture.
Environmental pollution is a global problem of our age. In agriculture, the most important thing is to preserve the ideas of sustainable development, because only these can ensure the protection of production resources, which will ensure the continuous production of agricultural products. Present environmental conditions pose a more problematic challenge to agriculture. -
Mitigation of environment impact of mycotoxins produced by Fusarium species
159-164Views:139The Fusarium fungi hazards the grain quality of cereals, therefore significantly affects their utilization as animal feed or consumable product. The Fusarium can decrease the quality of wheat in different ways: decreases the germination capability, causes visible discoloration, mould may appear, reduces the dry material and nutrient content of the grain, causes mycotoxin infection – as a result given by its by-product. Micotoxins produced by Fusarium genus, as the trichotecenes (T-2, HT-2, deoxynivalenol, nivalenol, diacetoxyscirpenol, Fusarenone-X) and the zearalenone (F-2) are the most common in Hungary. Occurrence of fumonisins first discovered in 1988 are must be identified carefully. About 20–30% of the overall worldwide production of cereals is infected with Fusarium and its toxins, which situation is similar in Hungary. This infection causes serious yield-losses in cereal production. In the case of cereal products, which non-utilizable as forage seems, an optimal solution is utilizing as biogas raw material, but it is also important to examine the effect of the infected cereal on the anaerobe digestion process.

Food problem and its solution
19-23Views:111The Globalization processes substantially changed relations between countries. One of main factors of these processes is forming in ХХ century of Worldwide auction organization, which activity provided with swift growth of volumes in trade of food commodities. Thus, the solution for global food problem was found. At the end of the second half of ХХ century the production volumes of agrarian goods in countries with a different level of economic development grew considerably. However, a food crisis 2007–2008 led to the necessity to define factors, which would allow to grow production, converting an agrarian sector into sustainable growing industry, passing ahead the increase of quantity of population. -
Influence of 17-alpha methyl testosterone on the production parameters of common carp (Cyprinus carpio L.) fry
37-43Views:221During our research we aimed at finding an answer as to what extent the different concentrations of 17-alpha methyl testosterone incorporated in the diet of common carp fries can influence the production parameters of the species, as well as how efficient their sexreversal can be with the use of this method. To this end, an aquarium experiment was conducted in the course of which four different hormone treatments were set and monitored. The fish feed was enriched with 17-alpha methyl testosterone in 50 ppm, 75 ppm, 100 ppm, 500 ppm dosages.
The obtained figures revealed that the hormone treatments had no influence on the production parameters and conservation of the common carp fries. Further on, our team is to determine the sex of the fish through the examination of gonads during autopsy when they reach the 500 g average weight.
Furthermore, a male specific test method which was supposed to be of great help in our attempt to select the sex-reversed specimens in the subsequent processes was also put to the trial. During the experiment the DNA-isolation of different sample types (muscle tissue, fin, mucus) of common carp with identified sex was successfully carried out. The extracted PCR product was examined with agarose gel. Our results indicated that the ccmf2 marker was applicable, however, the obtained figures were not reliable.

Some strategic aspects of animal protein production
11-19Views:178The access to food shaped human societies and dietary models throughout the history of mankind. Animal protein consumption became a part of human culture. Data are presented showing the relationship of daily calorie and animal protein consumption as affected by capita GDP changes. Examples are presented how genetic improvement of animal and fodder plants influenced the resource efficiency and the overall environmental footprint per unit product. The two examples presented are: the dairy industry of the USA the 1944 and 2007 situation, and the Hungarian broiler chicken sector considering data relevant to 1930, 1960 and 2010. In both cases, dramatic improvements in resource efficiency could be demonstrated. The agricultural area required to animal feed production was reduced by more than 80% in both cases per unit product. Future possibilities are briefly discussed, referring to the still unutilized land reserves of the Globe, the new evolving technologies in progress inclusive the CASPR/Cas 9 genetic editing methods.

Energy forests or vineyards?
237-240Views:67This 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. -
The effect of season and fertilizer on the LAI, the photosynthesis and the yield of the maize hybrids with different genetic characteristics
27-34Views:72The experiment was carried out in Debrecen, at the Experimental Station of the University of Debrecen Centre of Agricultural Sciences, Department of Crop Production and Applied Ecology. We tested 10 various hybrids with their own genetic characteristics for five different fertilizer doses, in addition to the parcels without fertilization. The three factors of production technology jointly determine the successfully of maize production, but in different measure. The yield and the stability of yield of maize can be increased with hybrid-specific technologies.
In 2004-2005 experiment years the favorable results reached were due to the rainy season. There were significant difference between the productivity of maize hybrids. The N 40, P2O5 25, K2O 30 kg/ha treatment caused the highest increase of yield (3-5 t/ha) compared to the control (parcels without fertilization). The reaction of hybrids to the further fertilizer doses was different. The agro-ecological optimum of NPK fertilization was N 120, P 75, K 90 kg of the most hybrids.
During the experiment, we tested the moisture loss of the five hybrids. The seed moisture content at harvest was higher than in previous years due to the rainy seasons. The seed moisture content of harvest of FAO 200-300 hybrids were about 20%. It changed between 21-24% in the case of hybrids with longer vegetation period (FAO 400), the seed moisture content of Mv Vilma (FAO 510) was 24.21-25.04% in the average of fertilizer treatments. There is an important difference between the moisture loss ability of hybrids which changed 0.2-0.6%/day. The moisture loss of hybrids changed depending on the fertilizer treatment; usually, it was more favorable in the optimal fertilizer dose (N120+PK).
In the case of tested hybrids, we measured the highest LAI and photosynthetic activity at the optimal treatment, N 120, P2O5 75, K2O 90 kg/ha in the respect of efficiency and environmental protection, and the yield was high also for this treatment. There are significant difference between the LAI, the photosynthetic activity and the yield of hybrids, and these values could change depending on the treatment of fertilization. -
The effect of different fat content fish feed on the production parameters and meat quality of the hybrid striped bass
33-37Views:160The interspecific ’hybrid striped bass’ is the result of cross breeding. Their offspring have got good chances of growth and tolerate extreme water temperatures and the content of dissolute oxygen more than their parents. Furthermore, they are more resistant to diseases. Therefore, the hybrid is perfectly suitable for intensive fishery production.
Our experiment lasted for seven weeks. We analysed the indices of growth and production of the hybrid as the consequence of nurturing them with two feeds of high nutritive value during this period. We examined the content of fat and of fatty acids in the flesh of these fish. There were no considerable differences in terms of weight gain, feed conversion ratio and uneven growth between the two groups, while survival was less likely among the the fish which had consumed more fat. We demonstrated, examining the flesh of the individuals which had consumed feed containing lower fat content, that it was fattier and contained more dry matter than those that had been fed of higher fat content. Besides, the content of omega-3 and omega-6 fatty acids was higher in the fish that had consumed less lipids.

A gombatermesztés szerepe az átalakuló magyar mezőgazdaságban
15-22Views:82The structure of Hungarian agriculture should be changed before the EU accession. The new structure should fulfill EU requirements and also produce competitive products. Unconventional products (mushroom, fish, honey etc.) have a lot of advantages: they can be produced on small farms, their trade is mainly free of regulation and their markets are almost unlimited. This paper deals with one of these alternative agricultural enterprises, namely mushroom production. Hungarian mushroom production – in spite of difficulties – has witnessed remarkable expansion: it has increased its production by fourfold and its export by fivefold in less than ten years. The low level of wages gives Hungary significant advantage over its competitors. If we could ensure the appropriate infrastructure (technical advice, bank loans, etc.) the mushroom industry would become one of the most profitable sectors of Hungarian agriculture.

The effect of hybrid, nutrient-supply and irrigation on the grain moisture content at harvest and the starch-content of maize (Zea mays L.)
89-95Views:102Maize is a worldwide dominant plant. According to nowadays plant production principles it is important to investigate and optimize the site-specific nutrient-supply and other production factors, such as hybrid and irrigation, in the case of this plant as well.
At the Research Institute of the University of Debrecen, Center of Agricultural Sciences and Engineering, at Látókép the effect of nutrient-supply and irrigation on the quantity and quality parameters of different hybrids were investigated in a small plot long-term field experiment. In this paper we introduce the results regarding the corn moisture-content and the starch content of the yield.
We have chosen three maize hybrids – that have been bread in Martonvásár – for our investigations. The effect of macronutrients is investigated in this experiment on five levels. The half of the experimental area can be irrigated during the vegetation period – whenever it is needed – by linear irrigation equipment, but on the other half only the water amount originating from the precipitation can be used by plants.
In the year 2008 the hybrid affected the grain moisture content at P=0.1% level, while nutrient-supply had an effect at P=10% significance level. We haven’t revealed either any effect of irrigation or of interrelationship between production factors. It can be stated that there are differences between the hybrids on each nutrient-supply and on both irrigation levels. The grain moisture content increased parallel to the longer vegetation
periods.
The starch content of maize is mostly affected by the hybrid,
so on P=0.1% significance level. Regarding our results, it can be
stated, that the starch content shows a decreasing tendency
parallel to the longer vegetation periods. -
Comparison of Added Value between Bioethanol Production and the Most Important Animal Production Branches Based on Concentrated Fodder, as Potential Competitors
111-115Views:60There are an enormous amount (2-3 million t/yr) of corn surplus is available year by year in Hungary. Inland utilization is an unsolved problem, whereas export facilities of raw (unprocessed) material could not be regarded as optimal way because of logistical barriers and the very low producer’s price. There are two basic opportunities for the export of the surplus of maize with reduced transportational costs and higher value:
animal production and process of bio-ethanol. In Hungarian conditions both of them demand the same raw material so they should compete with each other for maize. Both need financial aid at least for the investment in order to reach profit. Decision makers are influenced by several factors in allocating of national supports between the differential branches, one of them could be the added value developing in the given vertical change. I will introduce and analyze the expectable added values of the abovementioned competitive activities.
