273-278Views:191Being aware of lands ecological resources’ natural conditions and particularities for different uses and crops is of great importance
for the big and small producers.
In this paper we present the main aspects regarding the quality of the ecopedological conditions. Here there are briefly presented the
physico-geographic conditions and the telluric-edaphic configuration of the area. Also, the structure of the main categories of agricultural
activities in the physical geographical areas (mountains, hills and plateaus, high and low plains and meadows) and main soils’ types and
associations are presented. Lands vocation for different use (arable, lawns, hay, orchard, vineyard
The paper ends with highlighting the necessary measures for a lasting administration of ecopedological resources in the studied area. -
Environmental Conditions of the Berettyóújfalu Sub-Region
403-413Views:202The purpose of this paper is to introduce the environmental conditions of the Berettyóújfalu sub-region, which is geographically located in Hajdú-Bihar County. I specifically target the regions’ relief, soil and hydrogeological conditions, climate, flora and fauna, natural value and present nature conservation activities.
On the basis of my investigation of these points, I can state that although this sub-region has unfavorable soil conditions, polluted surface and subsurface waters, it is rich in thermal waters, nature reservations and wildlife. It’s disadvantageous characteristics can or should be amended, while the advantageous ones should be utilized by considering the principles of sustainability. At the end of this paper, I will make recommendations in connection with the latter point. -
Causes of floods and flood protection in Subcarpathia
72-75Views:188Subcarpathia is one of the richest regions in surface waters in the Ukraine. Due to its geographical, relief and climatic conditions, it belongs to the active precipitation zone, where great floods frequently occur. As a result of many years of observation, it can be concluded that the interactions of many natural factors can lead to various floods in the catchment area of the river Tisza. These are mostly hydro-meteorological factors, which can lead to great floods with the characteristics of the formed flow. Human activity also significantly influences the occurance of floods: clearing, which can accelerate the process of the runoff, ploughing in the catchment area, which can lead to erosion and the utilisation of areas endangered by floods for various economic sectors.
A series of questions arose in recent years regarding the formation of floods: what could be the causes of floods and what actions need to be made to prevent them. The evaluation of floods made us conclude that passive protection by using dams does not always ensure protection against floods as these were constructed in different times for different water levels. Many factors can affect the whole process which cannot be foreseen, therefore the development of new solutions and new technologies is necessary in flood protection. -
Study of plant production modells with different intensity in winter wheat production
51-60Views:419The effects of crop rotation, nutrient supply and plant protection technologies were examined on the yield of Mv PÁLMA winter wheat variety and on the most important diseases of ear and leaf. Our experiments were carried out on chernozem soil in the Hajdúság in 2006 and 2007, and three plant protection technologies (extensive, average, intensive) and three irrigation variations (without irrigation, irrigated with 50 mm, irrigated with
100 mm) were applied in different crop rotation systems.
In the triculture crop rotation a higher rate of infection was observed than in the biculture crop rotation, because the vegetative growth was more expressed after pea and these microclimatic factors were favourable for the development of pathogens.
In the triculture crop rotation (pea – wheat – maize) the powdery mildew, DTR and leaf rust of wheat were present in both examined years (powdery mildew 5-15%, DTR 14-42%, leaf rust 8-37% in cropyear 2005/2006, powdery mildew 12-32%, DTR 9-29%, leaf rust 8-26% in cropyear 2006/2007). Fusaria could be observed in 2006 (depending on the plant protection technologies and nutrient supply in the biculture 7-27% and in the
triculture 5-19%). With higher amounts of fertilizers the rate of infection increased and reached its maximum at the highest dose of nutrient supply (N200 +PK).
We observed the highest rate of infection by ear and leaf diseases in the case of the extensive technology, while this rate could be considerably reduced by the application of the intensive technology.
Both in 2006 and 2007, yields were the highest at the N100-200+PK levels in the triculture after pea (6028-7939 kg ha-1 in cropyear 2006, 6578-8690 kg ha-1 in cropyear 2007 depending on plant protection technologies), and at the N150-200+PK levels in the biculture after maize (6096-7653 kg ha-1 in cropyear 2006, 4974-8123 kg ha-1 in cropyear 2007 depending on the plant protection technologies). The highest yield maximums were
reached when pea was the forecrop. The yields on the experimental plots of the intensive plant protection technology was 224-2198 kg ha-1 higher (depending on the forecrop) compared to the plots where the extensive technology was used.
The highest yield without irrigation was at the N150+PK both in biculture and triculture crop rotation. Among the irrigated variations Ö2 and Ö3 at N200+PK fertilisation resulted in the highest yield in the biculture crop rotation, while the N100+PK level in triculture system. In the biculture crop rotation the extra yield was 14-51% higher (575-1225 kg ha-1 depending on plant protection technology) when 50 mm water was irrigated, and
15-54% higher (778-2480 kg ha-1) if 100 mm irrigation was applied comparing to the non-irrigated versions. The yield was 7-17% higher (560-1086 kg ha-1) in the Ö2 irrigation variation, and 8-23% (691-1446 kg ha-1) higher in the Ö3 irrigation variation compared to Ö1 irrigation variation (non-irrigated).
A correlation analysis was made to reveal the connection between the yield, the amount of fertilizers, the rate of infection, the plant protection technologies and the forecrops. Strong positive correlation (0.846) was found between year and fusaria infection. Strong positive correlation was observed between fertilization and powdery mildew infection (0.525), fertilization and DTR (0.528), fertilization and yield quantity (0.683). Lower
correlation was found between fertilization and leaf rust infection (0.409), and forecrop and yield (0.472), recpectively. Negative correlation was calcutated between plant protection technologies and DTR (-0.611), and plant protection technologies and leaf rust (-0.649). -

61-68Views:207The agricultural subsidies play a crucial role in the policy of the European Union. Remarkable part of the EU budget is dedicated to agriculture and rural development. The enlargement of the EU, the global changes in the market and other challenges are raising the demand for a better and more efficient way of work in the organization, using information and communication technologies, and especially the implementation of e-government
services. The article presents the Hungarian electronic claiming system (called eSAPS) for European founds in agriculture, and evaluates the first year of its operation. -
Formation of Food Clusters in Europe
55-59Views:196In the dictionary of foreign words and phrases we can find the word “cluster” with the following sense: aggregation, group and in a wider meaning: association, integration.
By explaining the geographical concentration of economical and innovation processes in the food processing sector, clusters, and especially
business clusters, play an important role. This essay deals exclusively with business clusters, so the term cluster is used also for business cluster.
I tried to collect the most relevant indicators determining the formation of clusters in the Food Processing Sectors and to analyze whether a
correlation can be found among the analyzed indicators. -

Evaluation of automated anaerobic fermentation processes as in the case of mould infected maize
81-86Views:520In Hungary the renewable energy utilization is planned to achieve 13% by 2020. Biogas production is one of the fields with the largest energy potential. Achieving high efficiency during continuous production despite the mixed and variable composition of input materials is the most common problem which the newly built biogas plants using agricultural raw materials have to deal with. The first experimental reactors at the Department of Water and Environmental Management were built 12 years ago. Control and automation of the four separated bioreactors were executed with ADVANTECH GENIE 3.0 software which granted pre-programmed measurement and points of intervention for pH, temperature, CH4, CO2, H2S, and NH3. The system became out-of-data, therefore in 2010 it has been redesigned and tested. The system is controlled by Compair Proview SCADA (Supervisory Control and Data Acquisition) software running on Linux platforms. The Fusarium infection caused serious yield-losses in cereal production in 2010. In the case of cereal products, which non-utilizable as forage seems an optimal solution is utilizing as biogas raw material. The raw material was based on the Fusarium infected maize. In the recent publication infotechnological and technological experiences of the pilot test period are evaluated as well as direction of future development is defined.

Sporting habits of students at the University of debrecen Centre for Agricultural Sciences
155-162Views:212In 2007, a new sport strategy was implemented, (XXI National Sportstrategy), which analyses the current conditions in recreational sports in Hungary and describes its developmental potentials. Additionally, last year a new concept for university sport was introduced (Hajos Alfred Program), having as its most important goal, to develop the recreational sporting activities within the universities’ environment. The latter is of high importance, as this is the last period, when, on an institutional level, we can establish and enhance the need for physical activity among young generations. In this study recreational sport is analysed in the University of Debrecen Faculty of Applied Economics and Rural Development. The purpose of the study was to analyse data on the sporting habits of the faculty students, their preference of where they like to exercise, within or outside of the university campus, and the reasons which can be found behind these preferences. Moreover, this study aimed to evaluate the service quality offered in university recreational sports. Data collection was completed on a paper based questionnaire, 42 closed-type questions were included and a total of 123 students completed it. Based on the results, college students usually complete their competitive level sport activity when they enter college and they continue this activity on a recreational level. Almost two third of them choose to exercise in places outside of the university campus. For those who choose university facilities for their recreational exercise, they do so because; it is usually cheaper and closer to access. In the service quality results we see, that females are less satisfied with teaching staff quality than males, it may be possible that females need more and more effective implementations in order for the universities to better satisfy their needs for physical activity.

The effect of sulphur and nitrogen supply on the growth and nutrient content of spring wheat (Triticum aestivum L.)
65-70Views:446Sulphur is an essential element for plants. Decreasing sulphur deposition from the air, and the use of more concentrated phosphate fertilizers, which contain no sulphur, has led to reports of sulphur deficiencies for wheat. Sulphur deficiency significantly affects yield and also the quality of wheat. The pot experiment was set up on calcareous chernozem soil at Látókép, Hungary, test plant was spring wheat (Triticum aestivum L). Seven treatments were used where nitrogen and sulphur were supplied as soil fertilizers in increasing rates (NS1, NS2, NS3) and in foliar fertilizer as well (NS1+fol., NS2+fol., NS3+fol.). Plant aboveground biomass production was determined in samples taken in the stages of development BBCH 29-30, 51-59, 61-69, 89. The nitrogen and sulphur content of straw and grain were measured. N/S ratios of grain and straw were calculated. The weights of grain were ranging between 8.6–16.1 g/pot. NS2 and NS2+fol. treatments produced the highest values. Foliar fertilizer had no further effect on grain. Analysing the values of the straw, it was observed that tendencies were similar to values of grain. The NS2 treatment produced the highest weight of straw and the NS3 rate already decreased that amount. The obtained results show the unfavourable effect of excessively high rate applied in NS3 treatment. The supplementary foliar fertilizer had no significant influence on the weight of straw. Both N and S-uptake of plant was very intensive at the stem elongation stage, then the N and S-content of plant continuously decreased in time in all treatments. The N-content of grain ranged between 2.215–2.838%.The N-content of grain slightly increased with increasing of nitrogen doses. In the higher doses (NS2, NS3) foliar fertilization slightly increased the nitrogen content of grain, although this effect was not statistically proved. The N-content of straw varied from 0.361 to 0.605%. The growing dose of soil fertilizer also considerably increased the nitrogen content of straw. Foliar fertilization further increased the nitrogen content of straw. The S-content of grain ranged between 0.174–0.266%. The lowest fertilizer dose (NS1) significantly increased the sulphur content of grain. The further increasing fertilizer doses (NS2, NS3) did not cause additional enhance in sulphur content of grain.The foliar fertilizer also did not change the sulphur value of plant. The increasing amount of soil fertilizer and the supplementary foliar fertilizer had no effect on the sulphur content of straw. The treatments influenced the N/S ratios of grain and straw. On the basis of experimental results it can be concluded that the examined nitrogen and sulphur containing soil fertilizer had positive effect on the growth and yield of spring wheat grown on the calcareous chernozem soil. The soil fertilizer application enhanced the grain nitrogen and sulphur content. The highest rate of fertilizer (600 kg ha-1) proved to have decreasing effect on the yield. The sulphur and nitrogen containing foliar fertilizer did not have significant effect on the yield parameters but slightly increased the nitrogen content of plant. -
A new model for predicting carbon storage dynamics and emissions related to the waste management of wood products: introduction of the HWP-RIAL model
75-81Views:351The ability of wood products to store carbon allows for their significant contribution to the climate mitigation efforts and the emission reduction commitments set by the EU. In order to optimise the carbon storage capacity of wood products, it is important to take climate mitigation aspects into consideration as much as possible during their production, use and waste management. The aim of this study was to quantify the effects of product development, recycling, and waste management technologies on carbon storage and emissions. In the frame of the ForestLab project, a new model and decision support tool was developed, which is able to predict the duration of carbon storage of wood products and the evolution of emissions from them. The developed HWP-RIAL model (Harvested Wood Product Recycling, Incineration And Landfill model) uses the methodology of the Intergovernmental Panel on Climate Change (IPCC) to calculate emissions, which is also used in the National Greenhouse Gas Inventory report. It combines the IPCC waste model with equations describing the carbon storage and emissions of wood products, and the model is also supplemented with a self-developed recycling and waste routing module. This paper provides insight into the operation of the model by following the life cycle of 200,000 m3 particle board.

A genetic study regarding the number of grains in spike in winter wheat
19-22Views:163Grain number per spike was studed in 6 winter wheat varieties and all their 30 direct and reciprocal F1 hybrids. Parents
included 4 released Romanian variety, the old american Atlas 66 and a dwarf breeding line, Oradea 79. This line has a low number of
grains/spike, but is important in breeding program for here reduced height. General and specific combining abilities were computed and
genetic effects were estimated using Griffing’s method 1, model 1, as modified by Cabulea (1983).
For this diallel crosses, gene interactions and the interaction between cytoplasm and nuclear genes were highly significant and
the ratio of additive and non-additive effects was close to one.
The variety Fundulea 29 showed the highest general combining ability and it is recommended as a good parent for increasing
grain number/spike. Mid-parent heterosis was significant in 9 out of the 30 cases, mostly in hybrids involving the breeding line Oradea 79.
In 3 cases the number of grains/spike of F1 hybrids was significantly lower than the average of the parents. The breeding line Oradea 79 had
a significant negative general combining ability, but showed significant positive specific combining ability in most crosses, as well as a
significant positive effect of its cytoplasm. These results are considered to indicate that there are chances of improving the grain
number/spike in some crosses with Oradea 79. -
Environmental Indicators – Agri-Environmental Indicators
248-255Views:178close relation. This means that policies related to the economy and the environment cannot be handled without each other. The United Nations Conference (Stockholm, 1972) was the first global conference to signal that environment concerns have increasingly become subject of mainstream socio-economic policies. The process started in the Seventies, laying emphasis on environment protection, plays an important role in the policy of international agencies. The use of environmental indicators is essential for monitoring the effects of environmental measures. The best way of evaluating sustainability if the results can be compared on a global level. International efforts are being made by the United Nations (UN), the Organisation for Economic Co-operation and Development (OECD), the Statistical Office of the European Commission (Eurostat) and other international agencies to develop a framework for environment statistics. This study deals with these frameworks, paying attention to agri-environment indicators. Hungary became a member of the UN in 1955, of the OECD in 1996, and will become a member of the European Union in 2004. The first summary in connection with environmental indicators of Hungary, taking the OECD Pressure – State – Response framework as a basis, was published in 1994. As a result, comparability of environmental indicators for Hungary with those used international are given.

Economic policy strategy of UNITAB
83-90Views:189Under the leadership of the International Association of Tobacco Producers – UNITAB – there is a struggle going on for stabilizing the situation of European tobacco growers. UNITAB unites the tobacco associations and tobacco growers of all EU countries.
Tobacco production ensures economic stability for more than 100 thousand small- and medium-sized farms in the rural areas of 10 EU countries. In addition, its social importance in the survival of rural communities is emphasized by the 400 thousand direct or related seasonal jobs.
Within the framework of the CAP reform, the European Union is gradually changing the regulations of production. This is based on the decoupling of subsidies, which will be implemented in two phases. Between 2006 and 2009. the decoupling will be 40% and then after 2010, 50% (the other 50% will be used for restructuring within the second pillar). The question is raised, how will the second 50% be restructured to the second pillar. Between regions and how it can be ensured that this support would go to tobacco production.
With its participation in the principles of the European Tobacco Charta, UNITAB targets for production under economically-balanced conditions, the production of products meeting the customer requirements, consideration of the working conditions (especially for seasonal workers) and adherence to the health regulations related to the consumption of the end product already in the production and environmental protection. They aim to ensure the survival of the sector via tobacco growing with sustainable development and high quality. To maintain the continuity, there is a need for the support of regional, national and EU authorities. Future of the sector is dependent upon adaptation of tobacco growers and upon meeting the social expectations.
According to UNITAB, efforts should be made to modify the decisions so that the majority of the funding could be used by the grower. The tobacco industry has been able to effectively fight for its survival. -
Effect of using antioxidants as feed additives in the diet of dairy cows on the vitamin E and lycopene content of milk
69-72Views:370In 2007, the aim of an Ányos Jedlik program and call for tenders was to support application-oriented, strategic research and development projects, which can increase the competitiveness of the Hungarian economy. In the framework of our project, we intended to examine whether non-protected antioxidants – in this case: vitamin E and lycopene – used as feed-additives can increase the antioxidant content of milk. The milk with an
increased level of vitamin E and lycopene content can be used for producing functional foods which will represent competitive products on the current market of milk products. Our results show that the use of vitamin E as feed-additive can significantly increase the amount of vitamin E in the milk. The use of lycopene as feedadditive also gave good results. At the beginning of the experiment, the lycopene content of the milk was below the detection limit, while in the post-feeding milk samples the lycopene became detectable. Based on our results, we are of the opinion that further experiments and analyses are needed regarding the quality of food of animal origin and animal health. -
Alternative rating methods of the LEADER programme
175-177Views:190LEADER was one of the most important and diverse initiations in the rural development policy of the recent years that made it possible in the Member States of the European Union to carry out the needs of the lowest level, directly coming from the citizens. Decentralisation and the assignment of certain authorities furthered this opportunity, whereas it was greatly restricted by the strong centralisation and regulation of the program in Hungary. This was the reason why the Hungarian LEADER program did not achieve any measureable success in terms of the standards in the rest of the EU Member States. There is a need to change this practice that can be done by the complete Hungarian reform of the program.

Comparison of the sample preparation methods worked out for the examination of the element content of wine
77-82Views:426The examination of the potentially toxic elements content of the wines is not easy task, because the most elements are in little concentration (mg kg-1 or μg kg-1) in the wine and the wines contain great amount of organic matrix. The efficient sample preparation is essential for the accurate determination of element content. The eim of our research was to determine which sample preparation method will be the most efficient in examination of wines with ICP technology. The examined wine sample was a 2008 Chardonnay from the Eger wine region. We did the sample preparation and analysis examination in University of Debrecen, Centre for Agricultural and Applied Economic Sciences, Institute of Food Science, Quality Assurance and Microbiology.
We did the analysis examinations with ICP- MS (inductively coupled plasma mass spectroscopy). We always did the sample preparations and the examinations in three times rehearsal. The applied sample preparation methods: dilution with distilled water, open digestion and microwave digestion.
We were able to measure B, Al, Mn, Fe and Zn with only dilution and open sample preparation. In the smaller quantity present Sr and Ba were measurable in the wine in the case of all three methods well. We were able to measure the Co with dilution and open digestion method, while Cr, Ni, and Te with only dilution method. In the case of arsenic we were not able to measure reliable result with dilution and open digestion method because of organic matrix and other components
(alcohols, monosaccharides, polysaccharides, polyalcohols and inorganic salts). On the whole we are able to say that in the case of certain elements (B, Mn, Fe, Zn, Sr, Ba) the open digestion and dilution sample preparation is applicable well, however, in the case of certain elements (As, Al, V, Cr, Se, Mo, Cd, Hg, Pb) we have to develop the methods. It may be development of one of the way, if we develop sample preparation methods to examined element specifically and not
to wine generally. -
Study regarding the influence of the nPK fertilizers use in long term trial on heavy metals concentration in wheat grains
107-109Views:242The paper presents research results obtained in stationary experiments, carried out at Agricultural Research and Development Station Oradea, regarding the influence of nitrogen, phosphorus and potassium fertilizers, on Cd, Pb, Cu, Zn and Ni concentration on wheat grains.
The minimum concentration of cadmium in wheat grains was recorded in the case of the unfertilized plot N0P0K0, 0.12 mg kg-1, and maximum value 0.22 mg kg-1, was registered at the fertilized plot with N160P80K120, relative difference relative to control was 84.2%.
Lead concentration had the lowest value in the unfertilized plot, the value (0.4 mg kg-1) being under the maximum allowed (1.0 mg kg-1). In case of the fertilized plot with N160P80K120, the lead concentration had the highest value, 0.47 mg kg-1, but even in this case it was located beneath the maximum limit allowed.
In all four systems of fertilization, copper has not exceeded the maximum allowed limit (5 mg kg-1), the values have been comprised between 1.68 mg kg-1 at the unfertilized plot and 2.81 mg kg-1 at the fertilized plot with N160P80K120. In other plots of fertilization copper had concentrations of 1.97 mg kg-1, at the fertilized plot with N80P40K40, and 2.78 at the fertilized plot with N80P80K80.
The lowest concentration of zinc, 26.47 mg kg-1, has been registered in the control N0P0K0. In the other fertilization plots studied, the zinc concentrations had the following values: 27.66 mg kg-1 (N80P40K40), (N80P80K80) 29.87 mg kg-1 and 33.62 mg kg-1 (N160P80K120).
Nickel has registered the lowest value in the unfertilized plot, 3.47 mg kg-1. The fertilized plot with N160P80K120 had the highest value 4.94 mg kg-1, with 42.39% higher compared to the control N0P0K0.

Examination of the vegetative and generative accomplishment of new apple varieties
29-34Views:242Our research focuses on apple varieties, what are planted expansively in the development apple orchards of Western-Europe, but about the production characteristics of these varieties we don't have or just few practical experiences in Hungary. These varieties can be described with regular and high yields, aesthetic and alluring appearance in their origin places, what ensure profitable producing for the growers. In our climate what tends to be often extreme (hard cold winters, late spring frosts, summer drought, heat stress) these varieties may behave differently, so before the substantial planting it is expedient to carry out variety evaluations to avoid the later failures. The place of our experimental is located in the Nyírség, what presents adequately the ecological conditions of the surrounding areas, so the gained results can be easily adapted in the biggest apple production site of Hungary. Regarding the vegetative and the generative parameters of the 14 examined varieties ('Schniga', 'Jugala', 'Fendeca', 'Galaval', 'Fengal', 'Red Cap', 'Early Red One', 'Jeromine', 'Crimson Crisp', 'Red Topaz', 'Red Jonaprince', 'Red Idared', 'Fuji SW', club variety) we found significant differences, which is the result of the genetically coded characteristics of the varieties, the effects of the vintage, the different training methods and the correlations of these factors.

Investigations on Mud on Heavy Metal Contaminated Flood-Plain of Tisza
96-101Views:788At the beginning of the year 2000 subsequently to a mine accident high heavy metal content mud entered the catchment area of the Tisza and was transported through the whole Hungarian section of the river. The majority of the heavy metals had been bounded to the floating sediment that was deposited on the flood-plain soil during flood forming a new, 5-10 cm thick layer. In the mud samples collected after the flood there was a clearly visible dark grey layer with significantly higher heavy metal content that was formed by the pollution wave and it was sorruonded by a light layer. The upper layer of flood-plain soils are formed from this mud layer during the soil development process, so the amount of Lakanen-Erviö soluble heavy metals that correlate with bioavailable heavy metal content was examined as well. In this case only the lead content was significantly higher in the dark layer.
New mud samples were collected after the 2001 flood. Separate layers could not have been identified, their colour was similar to those of the previous year’s light layers’. Comparing to this light layer the total Zn and Lakanen-Erivö soluble metal content was significantly lower in the mud samples of the year 2001. While the proportions of total and Lakanen-Erviö soluble metal concentrations were equal in both of the layers regarding the elements, these ratios have significantly changed next year regarding Pb and Zn: the amount of Lakanen-Erviö soluble metals considerably decreased.
As a result of sequential extraction the heavy metal content was rather low in the water soluble and exchangeable and NaOH-soluble fractions, so heavy metals found in the mud could be released in greater amount only in case of a heavy acidification. -
The effects of joining The European Union in the area of tourism within health tourism in Hungary
169-177Views:213The occasion of Hungary joining to the European Union caused difficult tasks and questions for tourism in Hungary. Tourism sector must have been prepared for joining to European Union, which means developing a well-functioning and future planning strategy. It has to improve taking parts our tourism into international market without significant deficit. The main aim is achieving the sustainable tourism by approach marketing and environmentally sound of way that is able to become competitive.
My aim is to analyze by numerous indexes what are the effects of joining Hungary to the European Union in tourism sector. However the results need to extend survey into many years. It is very important to reach long-term economic results and development, next to it has to be suitable impacts for social and natural environment, quality of life and developing health tourism as well.
To sum up we can establish extension of European Union area has improved diversity of tourism destination and goods, accessibility of natural and cultural features. -
Using research findings in precision maize production
227-231Views:639The effect of crop production factors on maize yield are examined on chernozem soil in a more than 30 year old long-term experiment on the Látókép Experiment Site of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen. The aim of research is to evaluate the effect of fertilisation, cultivation, plant number, genorype and irrigation. The analysis of the data in the database of the examined period makes it possible to evaluate the effect of maize yield, as well as that of the crop production factors and the crop year, while the correlations and interactions between these factors were also examined. During the examination of the cultivation treatments, it was concluded that the highest yield was obtained as a result of autumn ploughing, but its effect largely differs in the irrigated and the nonirrigated treatments. Based on our examinations, strip cultivation should be applied periodically (e.g. strip – strip – ploughing – loosening) in areas with favourable soil conditions free from compacted layers.
In years with smaller, average precipitation supply or when the precipitation was higher than average, higher plant numbers were more favourable. Under drier conditions, but especially in several consecutively dry years, a lower plant number can be recommended which is not higher than 60 thousand per hectare. In the case of favourable water supply, 70-80 thousand plants per hectare can be used. The yield increasing effect of fertilisation was significant in the case of both non-irrigated and irrigated conditions, but it was much more moderate in the non-irrigated treatment. The extent of weed coverage was significantly affected by the previous crop. In the case of a favourable previous crop (wheat), the weed coverage was significantly lower than after an unfavourable previous crop (maize). In the case of the same previous crop (maize), the extent of weed coverage was mostly determined by the crop year and the extent of precipitation supply. Irrigation is not enough in itself, because if it was not accompanied by intensive nutrient management, yields started to decline.
The results of researhc, development and innovation contributed to the technological method which makes it possible to apply locally adjusted sowing seed, fertiliser and pesticide in a differentiated way, as well as to change the method of operations within the given plot. -
The role of non-optimum Fe-Zn ratio in the development of latent zinc shortage in cucumber (Cucumis sativus L.)
7-11Views:246The general micronutrient deficiency of the soils influences the quality of food production which causes human health problems in several countries as well. The non optimal Fe-Zn ratio can cause latent zinc deficiency – which the plants response in the function of their sensitivity –what has no visual symptoms or the plant shows deficiency symptoms in case of appropriate zinc supply. This phenomenon can cause significant decrease in the crop yield.
The aim of this study was to prove the role of non optimal Fe-Zn ratio in the evalution of latent zinc deficiency.
The non optimal Fe-Zn ratio caused decrease in the number of the leaves, the number and length of the internodes, the relative chlorophyll contents and in the dry matter production. According to the results the non optimal Fe-Zn ratio caused difficulties in the metabolism, which decreased the examined plant physiological parameters in the most cases.

A practical means of setting the scene for evaluating aggregated absorption risk in EU co-funded programmes related to project failure
63-66Views:251The main purpose of the mid-term evaluation of grant programmes is to assess relevance, progress, effectiveness and efficiency. There are several methodologies, tools and techniques applied in various evaluations to assess these programme aspects. An important area of the evaluation of both the financial progress and the effectiveness of the programme is to evaluate the risk of absorption which is indicated by various factors, inter alia risk of supported project failure. If a project fails in any EU co-funded programme in the stage of preparation or implementation, then the fund already committed to that particular project (assumed to have already been absorbed or “spent”) is to be reused again or is to face decommitment (funds have to be paid back to the EU). There are strict EU regulations governing the time scale of this re-use (n+2, n+3 rules), therefore it is of major importance to assess the risk severity (measured as the resultant of the volume of grant at risk and the chance of project failure) and build up an early warning mechanism which indicates if the risk reaches a critical level that requires immediate intervention.
