The effect of Willow extract, Bistep and their combination on some quality parameters of lettuce (Lactuca sativa L.)
239-247Views:403The research described in this paper was conducted at the University of Debrecen, Farm and Regional Research Institute in its Botanical and Exhibition Garden, Hungary. The aim was to investigate the influence of plant biostimulants on the morphological parameters of three lettuce varieties (May King, Kobak and Great Lakes). Willow bark extract and Bistep were used through irrigation and spray onto the plant leaves with the amount of 5% Willow and 0,5% Bistep. Vegetative parameters like head structure (1….10), head weight (g head-1), head closing (1….10), number of leaves, head diameter (cm), internal stem size (cm) and root weight (g head-1) were measured in 2019 and 2020. According to our results, vegetative parameters are significantly affected by plant varieties and treatments. In the experiment of 2019, important vegetative parameters were influenced by the Willow extract, while in the season of 2020 the most influenced parameters were under the impact of Bistep biostimulants followed by Willow+Bistep. However, the most favourable vegetative growth was recorded in the Kobak variety in the season of 2019 followed by May King and Great Lakes varieties in the season of 2020. On the other hand, the interaction effect of plant varieties and plant biostimulants on the vegetative parameters were varied from seasons. For example, for the season 2019, significantly the highest vegetative value was recorded for the interaction of May King variety treated with Willow extract, whereas in 2020, significantly the most influenced vegetative parameters were under the influence of the interaction of Bistep and May King variety followed by the interaction of Willow+Bistep and Kobak variety.

Strategic Steps in the Sheep and Goat Branches
61-68Views:590The balance of the sheep and goat branches can be summarised as follows:
If the increase in stock size, specific yields, genetic improvement and modernisation are not realised, several thousand shepherds will lose their jobs and possibilities to work, and their families will lose their only source of livelihood.
Several hundred hectares of grassland will become weedy and the costs of crop protection will increase in these regions. Pollen pollution, the number of allergic ailments and medical costs will increase, mentioning only the main disadvantages. Its financial requirement is nearly equal to the one required for development without any essential compensation or production.
In order to develop a competitive branch, a subsidisation of 10-20 billion HUF is needed until the accession of Hungary to the EU, depending on the scale and progressivity of development. The subsidisation and realisation of the strategic steps would result in:
– the establishment of a registered livestock with 1.5 million ewes, which would ensure better market position for the branch in the EU (5%),
– the establishment of a competitive and marketable branch with a production value of 15-25 billion HUF, calculated using the present price level (after accession, the branch would be self-operating and profitable, with the 6-8 billion HUF/year normative subsidisation by the EU),
– the establishment of a genetic potential which would ensure our participation in profitable international breeding animal market, which provides extra profit,
– the establishment of a sheep husbandry with better genetic potential and phenotypic performance, producing a quality of international level,
– the maintenance of the workplace of more than 10.000 people (saving 3-5 billion HUF/year of the budget),
– the maintenance of the condition of growing areas of grasslands with their advantages (crop protection and public health) whose financial effect is considerable. -
Characteristics of Corn Seed Sales in Hungary
78-81Views:233As seen on the above tables we can acknowledge the fact that the Hungarian corn seed market is very unique and, because of its size, indispensable for all multinational breeder companies. We can also assume that the main places in the market are taken by big companies as Pioneer, with its unbreakable first place, followed closely by Syngenta Seeds and the fusionized Monsanto. Although the Hungarian breeders’ hibrids perform on field tests and trials similarly or better than other varieties developed by the above mentioned companies, we can’t find them even near to those leading few given mostly by Pioneer, Syngenta and Monsanto hibrids. This fact leaves us with a conclusion that the Hungarian companies should change the strategy of their marketing procedures to increase sales.Thus, they need better technology to keep up with their competitors, more advertisement, other marketing „hints”, which can only be fulfilled with a big economical background, unfortunately not yet available for our breeders.

Mobile Internet Usage Possibilities and Requirement in Agriculture
394-402Views:175In this paper, I looked at the mobile Internet from technological, economical and sociological aspects and then pointed to several agricultural possibilities for theri usage. Examining the effects and driving forces of mobile communication, I can say that it is a very complex system. The social connections of mobile communication and the arising problems show that it affects several areas of everyday life. By looking at the business processes, all costs, advantages and disadvantages can be seen clearly. Overview the mobile Internet from the technological aspect and I discuss related technology and applicable utilities, as well as two possibilities for using wireless Internet: 3G and WiFi. Among the possible usages, I gave several examples to give an impression of all the diverse possibilities this technology offers. There are some really useful applications in customer service, precision farming, transport, agriculture and food industry. Finally, I talked about the mobile Internet in Hungary and in the other EU countries.

Evaluation of blue and red corn landraces
239-243Views:378Corn breeding can be successful only on a broad base of genetic material. The expansion of breeding aims includes the research of germplasm materials. In our experiments, we examined 11 blue, purple and red exotic corn varieties on two locations in Hungary. We conducted a complex study to obtain more information. We studied several morphological and phenological features and determined the most important qualitative parameters (protein, fat, ash). We applied the Tassel Area Index (TAI) under Hungarian conditions and compared it with the pollen producing ability of different genotypes. Results show that there are great opportunities in exotic corn varieties. Their quality exceeds that of the yellow ones in many cases. There are significant differences in yield and nutritional parameters. The favorable nutritional composition is not coupled with great productivity. Based on their flowering time and their agronomical features, they can be cultivated under Hungarian conditions as well. They match the new breeding aims, so they can be used as functional food or energy plants. With their high pollen producing ability and TAI, they can be utilized as markers in future pollen research.

How can we determine the expected prices for lambs? – Analysis of the Hungarian and Italian lamb prices
59-67Views:167The Hungarian sheep sector has become a one-market sector, almost the whole amount of slaughter lamb went to Italy, which increased its defenselessness. In addition to the sole Italian market showing a permanent demand for Hungarian lambs, it would worth to exploit possibilities in other European markets considering the seasonal differences in Italian prices. Such markets can be the Spanish and Greek for ”light” and the French, German and English markets for ”heavy” lambs. Both the Italian and Hungarian prices have three major periods: Easter, Ferragusto and Christmas. Due to the changes in the prices, the producers often suffer great losses, therefore, the temporal adaptation of production, market research, technological and development activities need to be improved. It is important that the living of Hungarian sheep breeders should not be dependent solely upon the Italian market, distribution of products should be ensured in other markets too, so that the safety of sales be increased and higher prices and higher income could be achieved. The European lamb prices are characterized by large seasonal fluctuation and the degree and timing of changes are different in the different countries. Study of the literature and the results obtained in my study on lamb sales called for an analysis and study of the possibilities of price forecasting. In my study, I performed a forecasting of lamb prices in Hungary and Italy for the period between 1996 and 2006 based on the data of the European Committee. Among the forecasting methods, seasonal decomposition and SARIMA models are the most precise, producers can achieve a better market position by using these in the practice.

The age and the growth of the european weather loach (Misgurnus fossilis)
37-44Views:449The possibilities of examination the growth of fish species are verry difficult, and much of methods are oblique. With the weather loach is the work especially complicated through the small scales. Till now the growth of weather loach is in Hungary unexamined.
We applied self developed catch method in three explored channel. The length and weight measured on the fishes alive, as well the sexing. We analysed the datas with Bertalanffy-method.
The growth of the fishes is different, but the growth of the body length was nearly the same in the three channels. The one year old fishes can growth to a maximum of 130-140 millimeters, the two years old fishes can growth to maximum of 180-190 millimeters. Longer fishes by 180-190 millimeters are 3 or more years old. The data of sex-ratio is deviant than the literature wroted. The fish from Fényes are growing faster, than the others. This species can be 190-200 millimeters long after 2 years from birth. It is a very fast growing. -
Investigation of the heat shock gene Hsp70 polymorphism in different sheep genotypes
41-45Views:526Nowadays the climate change has an increasing effect on the animals. The warming climate brings up several problems on the area of the animal husbandry, which ones are really important. From the first time the living beings have defensive mechanisms against the heat shock. In current examination we use– from Hungary and from other countries collected –samples of sheep breeds, which are living on different climate. Our fundamental assumption was, that the animals living on other climate adapted to the changes of the environment and there are differeces in their genetic background. These fixed mutations we are looking for in the HSP70 heat shock gene, but we haven’t found any polymorphism yet. We are going to involve further breeds and more individuals in the investigations.

Periphery formation and economic-social conflict
87-90Views:260The timeliness, significance and importance of the study is sensitively shown by the fact that a large part of the Tisza region is slowly being moved to the periphery in the slowly modernising and changing economic and settlement spatial structure of the Great Plain. This situation is also deepened by the fact that the social and economic backlog increases in the majority of the region, as one third of the 33 most disadvantaged small regions in Hungary can be found here. This study basically contributes to the establishment of the development of the Tisza river’s spatial environment and the development of new solutions.

Examination of the conditions of extreme water balance circumstances (water logging, drought) with environmental information technology tools
79-86Views:563The Carpathian Basin is characterized by varying hydrological extremes, both in space and time. Hungary's natural endowments are more favourable than average, especially for agricultural production, with 5,3 million hectares of land we have which is suitable for agricultural production. These extreme water management are often occur in the same year and mostly in the same region, which may become more frequent in the future, especially in the lowland regions. The negative impacts of extreme water management was influenced by the land use changes in recent years, which has modified the runoff processes of the affected regions.
The aim of the study was to research the formation of inland water and drought circumstances in two sample areas the Great Plain (Szolnok-Túri flat and Nyírség) by geoinformatic tools. During the investigation in the first step we determined that areas which are susceptible to inland water and drought, based on the AGROTOPO database. In addition, land-use categories of characteristics of the sample areas are evaluated according to the Corine Land Cover. Furthermore, after defining characteristic of NDVI values between the period of 2003–2013, we evaluated the effect of drought whether can be detected in crop failures in respective areas.
Based on our results, we concluded that the formation of inland water and drought circumstances can be investigated in a large spatial extension by geoinformatic tools and databases.

Yield and sward composition responses of a native grassland to compost application
35-38Views:386A 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.

Recent Graduates’ and Language Teachers’ Assessments of ESP Preparation in Hungary
182-187Views:220Like many teachers of ESP in Hungarian higher education, I have for several years been spurred to track and investigate those interrelationships that exist between the expectations of the multicultural European job market of the 21st century and the linguistic literacy competencies required of those young graduates that are searching for jobs in such an environment. What specific knowledge or rather, what specific combination of knowledge, skills and cultural competencies do they need in order to succeed? Are we, language teachers aware of the responsibilities we have in preparing our students for such challenges? This paper publishes partial results of a national survey conducted in 2000. The investigations involved 120 teachers of ESP in higher education and 71 young graduates of technical universities or colleges with different profiles. The queries covered a wide range of issues of which we will only be examining one – from two perspectives, though – here: a.) The retrospective satisfaction of recent graduates with the language preparation they received and b.) The teachers’ assessment of the importance of the components of the preparation they provided.

Evaluation of Two Heat Sum Calculation Methods in Maize Production
156-159Views:216Maize production is of primary importance in Hungary, especially considering that its cultivation takes up one of the greatest ratios of land used for agricultural production. As a result, the number of farms where maize is not cultivated for either food production or foraging purposes is insignificant. For this reason, establishing economic production is of decisive importance when it comes to determining the efficiency of farms. Profitable maize production depends on a number of conditions, including the professional suitability of farmers, while some aspects of production are independent from these. Heat-sum calculations form a transition from this aspect, since temperatures ocuring during the growing season cannot be influenced by man. However, the method of calculation and evaluation and thus the tool to improve production is in the hands of the farmer. This scientific paper aims to give a general description of heat-sum calculation methods.

Analysis of the efficiency of higher education systems
207-214Views:257The aim of the higher education reform process both in Hungary and in the European countries is establishing a competitive, qualitative higher education. The Education Minister of our country regularly emphasizes in his statements that the quantitative changes of he past 15 years are completed, from now the emphasis must be on quality :„a degree in itself is not sufficient, the actual knowledge behind is necessary”. To achieve
this aim, the government carried out several changes in the field of higher education in the past years, one of them was implementing a budget support system in accordance with the performance of the institutions. The objective of the three year long support agreement between the state and the higher education institutions is considering quality parameters and outputs beside and instead of normative (input-based) support. The other occurent and debated issue is the introduction of tuition fees. Although this plan was rejected by the national referendum on 9th March, 2008, some weeks ago an amendment bill was passed, which would mean bringing tuition fees back in the system.
In my paper I am examining whether the efficiency of higher education systems are influenced by the extent of the contribution of the state and the private sector to their expenses. Furthermore I’d like to find the answer to the following question: Does it matter what principles and mechanisms play role by the distribution of the state support between the institutions of higher education. -
Population date of Great Cormorant at the area of the Hortobágy Fish Farm Co.
51-54Views:584Hungary’s great cormorant stock did not use to be a considerable one before the 1980s. After that, their number has been rising significantly. The size of the stock now is rather stagnating or slightly growing. The presence of cormorants has been significant around ponds of the Hortobágy Fish Farm in the past few years. Due to considerable fish consumption of cormorants it is essential to know which and what kinds of units of the ponds (spawning, supply, and market) are preferred by the birds in order to see to adequate protection. The aim of our research was to discover any differences in the number of cormorants present at particular units of the fishpond system and certain ponds of equal kinds within them.
Our observations were in line with the methods used in ornithological researches. The experiment took place between April and October 2012 on a monthly basis. According to the results we found relevant differences in the number of cormorants based on the seasons and months as well. This fact was supported by statistical data. During the autumn and winter birds prefer supply and market purpose ponds while their presence here is vanishing during the summer. Relevant presence of cormorants around the area of the Old Fishponds (70 to 200 specimens) might be due to lack of disturbance and large sizes of the ponds.
Our research has great scientific relevance since it is vital to be aware of the preferred periods and areas in order to maintain effective protection; this way alerting activities can be applied in a more harmonized way. By keeping our research up as a monitoring activity, we will be able to receive more precise data later on.

Examination of the Nutrient and Water Utilization of Different Corn Genotypes in the Hajdúság
55-59Views:246The research was set up on chernozem soil at the Látókép MÉK research area of the University of Debrecen in Hungary. We examined the following factors of the hybrid P9494, P9578, PR37N01 and PR37M81 in 2013.Yield, yield production per 1 kg fertilizer, water utilization and nutrient reaction. We found that the best yield results were achieved at level N120+PK in case of hybrid P9494 (17 132 kg ha-1) P9578 (16 838 kg ha-1) and PR37N01 (17 476 kg ha-1) and at level N150+PK for hybrid PR37M81 (16 754 kg ha-1). Results of yield per 1 kg NPK studies indicate that the most intense yield growth occurred at level N30+PK compared to the control treatment. This means that yield production per 1 kg NPK was 39.2 kg kg-1 in the case of hybrid P9494, 54.2 kg kg-1 in the case of P9578, 17.6 kg kg-1 for PR37N01 and 44.2 kg kg-1 in the case of PR37M81. After comparing corn hybrids’ water utilization, our conclusion was that the control treatment achieved the worst results in the case of each hybrid (P9494: 20.8 kg mm-1, P9578: 21.0 kg mm-1, PR37N01: 26.2 kg mm-1, PR37M81: 19.5 kg mm-1). For hybrid P9494, P9578 and P37N01, the best water utilization results were measured at level N120+PK (31.5 kg mm-1, 31,0 kg mm-1 and 32.1 kg mm-1), while PR37M81 reached the highest values at level N150+PK (30.8 kg mm-1). We determined the hybrids’ nutrient reaction and its optimum fertilizer values. The best nutrient reaction results were achieved by hybrid PR37N01, while that of hybrid PR37M81 proved to be the weakest.

Susceptibility of maize hybrids to corn smut diseas
39-42Views:466Corn smut disease is one of the most common maize diseases. In the previous years the disease lost from its importance, however nowadays it is becoming more and more important and widespread. The protection against it encounters great difficulties, therefore it is important to emphasize prevention and resistance based protection. The aim of the research was to investigate under laboratory circumstances the resistance of Hungary’s most commonly cultivated maize hybrids to corn smut disease. Twelve species were investigated. We distinguished two susceptibility groups within the hybrids based on the investigated parameters. The results are intended to assist the protection against corn smut disease and to make a suggestion for the farmers so that they could apply more environmental friendly and economical production.

Carcass and the Meat Quality of Hungarian Lambs
65-71Views:481The author investigated 153 lambs of nine genotypes originating from breeding flocks, and 50 lambs originating from production flocks. The investigations were performed between 1995 and 1998. The authors discuss the evaluation of comformation and fat cover according to EUROP standards. The authors also investigate the proportion of valuable meat by genotype, and – out of the internal value indicators – the dry-matter, protein, fat, connective-tissue and hemin contents comparing the flavour, aroma, tenderness, and oven loss of the different genotypes.
The following findings should be highlighted:
♦ The Hungarian Merino breed should be improved, as – according to EUROP standards, more than 70% of these animals were rated as quality „R”.
♦ Hungarian fattening technology has to be preserved, as the lambs reach the desired slaughter weight within a short period of time, and without over-fattening.
♦ Readiness for slaughter, typical of each genotype, has to be defined, and slaughter at proper weight be achieved.
♦ It has to be re-evaluated whether the Hungarian Merino is the only breed which can be used in Hungary, as none of the investigations really proved the special characteristics and significance of this breed.
The author summarizes the findings of the investigation in five tables. -
Investigation of directions of crossing in maize (Zea mays L.)
43-48Views:301In Hungary, we examined eight features of twelve direct cross hybrids over a period of three years. The twelve hybrids were derived from direct and reciprocal crosses of four parental lines. We did not find significant differences in the cases of stalk diameter and leaf number in the average of 3 years in any of the hybrids. Statistically explainable differences in primary branches were observed in hybrids UDH5 and UDH8 and also in UDH6 and UDH11. It was evident in both instances that degrees of heterosis in reciprocal crosses far exceeded those of direct ones. High tassel branch number was dominant over the low one; consequently, parents with higher tassel numbers enforced their effects during the formation of this trait in hybrids. We experienced positive correlation (r=0.67**) between plant height and main ear height. A positive correlation (r=0.89**) was also found between the tassel length of the main axis above the lowest and the upper side branch. We observed a medium correlation (r=-0.42**) between the number of primary lateral branches and plant height. The number of primary lateral branches showed the highest heterosis. These results can be utilized in practical selection and seed production.

Tools of promoting „energy-crops”
47-52Views:190The utilisation of renewable energy sources have come to front with the decreasing fossil fuel stocks, the unsolved problems and fears of nuclear energy and so the cumulating energy dependence. In Hungary the potential of biomass is the largest in renewable energy sources.
During our examinations, we analysed the promotion of producing energy crops in Szabolcs-Szatmár-Bereg county. With the examination of the territories involved in energy crop subsidies it can be stated that the energy crop subsidy had its promoting role only on those areas where because of the bad soil conditions the energy crop producing is more profitable than other alternative (non energy) crops.
The expected growth rate of energy plantations will be low, according to the low rate of subsidy intensity (40-60%). The uncertainty of direct area payments decreases the calculability that cuts back the favour of investment in short rotation forestry planting. -
Reduction of ragweed pollution in industrial utilization system
69-72Views:269In Hungary 6.2 billion hectares are used for agricultural and from this area 5.0 billion are polluted by ragweed. In addition, the export of agricultural products will be threatened because of their pollution. Ragweed results also problems in human medicine because of its pollen allergy. More than 30% of the habitants are affected directly or indirect by allergyc diseases. On an annual basis nearly 60 billion HUF is spent on defense against ragweed. From this budget 30 billion HUF comes from the damage of the agriculture and other 30 billion for the cost of the therapy and health insurance. To solve the problems caused by ragweed needs new ideas. The proposals are the gathering and comprehensive utilization. A leap forward, from the ragweed new, market–orientated product should be developed.

Situation of small and middle sized enterprises in Northern Great Plain Region
69-72Views:244Most of the enterprises operating in Hungary belong to the group of small and medium enterprises (SMEs) which means that their total number of staff is less than 250. The aim of the study is to examine SMEs operating within the North Great Plain region. It provides a short summary of the general characteristics of the region, the situation and significance of SMEs based on the data 2009 and it also clarifies the relevant definitions. The data shows that the enterprise type that is most characteristic in the the region is joint venture (the most popular type is Ltd). It can be laid down as a fact that the number of micro and sole entrepreneurs is also significant in the area. It is also clear that the majority of small enterprises deals
with commerce, while most of the medium enterprises are involved in industry (processing industry). As a continuation of the examination, size of investments, influx of foreign capital, ratio of employed people and grant opportunities are also to be evaluated since these factors influence the operation of enterprises as well. -

Plant protection praxis on Hévíz Nature Conservation Area (Lake Balaton District, Hungary)
81-83Views:311The nature conservation park, which belongs to the Spa and St. Andrew Hospital for Rheumatics of Hévíz, is 60 ha in size. The famous Lake of Hévíz, the two overfalls and the main buildings of the hospital are located in the middle of the park. They are surrounded by protective forests, parks and gravel esplanades. During the past few decades, the population of neophyton plants and invasive insects have increased considerably. These mean serious challanges to develop efficient control methods. Special care must be taken of environmental and plant protection regulations. Keeping plant protective regulations are especially strict around natural and spa waters.

Technological development of sustainable maize production and its effect on yield stability
379-388Views:420In 2015 and 2016, we examined the effect of NPK nutrients, sowing date and plant density on yield on typical meadow soil. The amount of precipitation was 282.0 mm in 2015 (January–September), 706.0 mm in 2016 and the 30-year averageis 445.8 mm.Agrotechnical factors:– Experiment a)5 Dow AgroSciences hybrid with three sowing dates and three plant densities– Experiment b)In 2015 eight, in 2016 ten hybrids with different genetic characteristics and growing seasons, with control (without fertilization), N80+PK and N160+PKtreatments, five plant densities (50–90 thousand) with 10 thousand plants difference between the different densities.
In a drought year, we reached the higher yield in the earlier sowing date and with the lower lower plant density of 70 thousand plants ha-1-. The maximum yield, depending on the agrotechnical factors, was 10–12 t ha-1 in 2015, while in 2016 it was 14–16 t ha-1. Yield stability can be increased using hybrid-specific cultivation techniques.
