    This paper discusses open source software which became one of the most important trends in the software industry recently. The most often asked questions in this area are those related to intellectual property rights. The author used a more general approach and tried to give a survey of the advantages and disadvantages that the market players (developers, government and last but not least users) have to face.
    After sketching the history of open source software and discussing some of the prevailing definitions, we turn out attention to the starting point: what motivates the developers? Then we give a general overview of the advantages and disadvantages of open source software. In the next part, the author analyses the software policies of the EU partially based on the abovementioned advantages and disadvantages. Finally the paper concludes with the discussion of user benefits and costs.

  • Optimized balance between crop productivity, restoration and maintenance of vital soil functions and soil carbon sequestration and storage – the SmartSOIL (FP7) project

    Soils provide the most indispensable function of supporting the production of food and feed for a growing human population. At the same time they provide a range of regulating and supporting functions related to climate change and removal of greenhouse gases. The majority of the soil functions are closely linked to the flows and stocks of soil organic carbon (SOC); low levels of both flows and stocks may seriously interfere with several of the essential soil functions and thus affect the ecosystem services that soils deliver. Soil degradation is considered a serious problem in Europe and a large part of the degradation is caused by intensive cultivation practices in agriculture. The aim of the SmartSOIL project is to link the results of different scientific fields through a holistic and multidisciplinary approach and as a result develop a decision making tool contributing to sustainable development.

    This study analyses how the level of postharvest technology’s development influences the economic efficiency of apple production with the help of a deterministic simulation model based on primary data gathering in producer undertakings. To accomplish our objectives and to support our hypotheses three processing plant types are included in the model: firstly apple production with no postharvest and prompt sale after the harvest, secondly parallel production and storage combined with an extended selling period and thirdly production and entire postharvest infrastructure (storage, sorting-ranking, packing) with the highest level of goods production and continuous sales. Based on our results it can be stated that the parallel production (plantation) and cold storage, so the second case is proved to be totally inefficient, considering that the establishment of a cold storage carries enormously high costs with resulting a relative low plus profit compared to the first type of processing plant. The reason for this is that this type is selling bulk goods without sorting-grading or packaging; storage itself – as a means of continuously servicing the market - is not covered properly by the consumers. Absolute efficiency ranking cannot be established regarding the other two processing plants: plantation without post-harvest infrastructure resulting lower NPV, but a higher IRR, DPP and PI as developing a plantation and a whole post-harvest infrastructure. Former processing plant type is favourable considering efficiency ratios describing capital adequacy, while the latter is in terms of income generating capacity.

    Wheat is one of the most grown crops around the world. Its primary use is in the production of bread, bakery, and confectionery. The provision of essential nutrients, mainly nitrogen, plays a pivotal role in the growth and development of wheat. The wheat varieties used in the experiment are Alfold and Mv. Menrot. The rates of nitrogen used in the experiment are: 0, 200, 400, 600, 800, and 1000 kg N ha-1. The aim of this study is to evaluate the effect of nitrogen fertilisation on technological quality of wheat and to find the appropriate fertiliser rate to reduce pollution. The results indicate that nitrogen fertilisation did not show a significant effect on thousand kernel weight and test weight. However, nitrogen fertilisation significantly affected protein content, gluten content, Zeleny sedimentation index, and the falling number. The higher the nitrogen fertilisation the better the technological quality parameters of the wheat. The protein content, gluten content, Zeleny sedimentation index and the falling number were the lowest at 0 kg N ha-1 followed by 200 kg N ha-1 then 400 kg N ha-1 and the highest at 600 kg N ha-1.

  • Baking quality of winter wheat (Triticum aestivum L.) in the long-term experiments on chernozem soil

    Agriculture 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.

    In this study, energy utilization of biomass is introduced with a short description of renewable energy sources and utilization possibilities of biomass.
    Presently, the necessity of renewable energy sources is increasingly obvious. Among renewables, energy from biomass is to be highlighted, since this allows versatile, cheap utilization of the sun’s energy. In this respect, Hungary has advantages. Direct heat utilization and biogas production are available procedures today, whereas biodiesel and bioethanol are expected to spread in the near future. Biogas production is possibly the most versatile method for biomass conversion: it can produce energy from materials inapplicable for other utilization; at the same time, it is capable of neutralizing harmful wastes; in the end, it produces also valuable fermentative products, from bio-manure useful in agriculture, to pharmaceutical raw materials.

  • Development of maize production technology that increase the efficiency of bioethanol production

    Maize is one of the most important crops worldwide and also in Hungary, it can be utilized for multiple purposes: as a feedingstuff, for human nutrition and for industrial processing. In the last decades, the per ha yield of maize varied greatly in Hungary, between 2004 and 2006, it was 6.82-7.56 t/ha, while in 2007, it was only 3.6 t/ha. Resulting from this, the price of maize became 2-2.5 times higher. The high price hinders bioethanol production. The largest per ton amount of bioethanol, 387 l, can be produced from maize.
    In addition to its classical utilization as feed and food, the industrial use (especially for bioethanol production) of maize is increasin.
    For industrial production, a new production technology is needed. I tested and selected hybrids appropriate for this purpose and set up fertilization and plant density experiments. The experiment were set up on chernozem soil in 2007.
    The applied fertilization treatment was N 120, P2O5 80 uniformly, and five different dosages of potassium: K2O 0, K2O 100 (KCl), K2O 100 (Kornkáli), K2O 200 (KCl), K2O 200 (Kornkáli) kg/ha active ingredient. The applied plant densities were 40, 50, 60, 70, 80, 90 thousand plants/ha.
    The yield of maize hybrids in the fertilization experiment ranged between 10.53 – 14.62 t/ha. Both regarding the form and dosage, 100 kg/ha Kornkáli proved to be the best potassium treatment. Regarding the inner content parameters, the highest starch content in the average of treatments was obtained for the hybrid PR36K67: 73.57%, and its yield was also the highest, so this hybrid proved to be the most suitable for bioethanol production. The highest protein content was observed for the hybrids KWS 353 (12.13%), which can be favourable for feeding purposes.
    Most of the hybrids gave the highest yield at 80 thousand plants/ha plant density, however, hybrids PR36K67 and Mv Tarján achieved the highest yield at 90 thousand plants/ha.
    In bioethanol production, the selection of a high-yielding hybrid with high starch content, a slight reduction of N, increase of potassium, the application of the highest plant densities of the optimum interval, harvest at full maturity (when starch content is the highest compared to protein content) are of great importance.

    During the 2014 year a fungicide application trial was made as a part of technology development in Debrecen (East-Hungary). Both in this trial and across in Hungary a serious stripe rust epidemic developed and caused great yield losses. The first sympotoms were observed in April on one of trial plots and during some following weeks a serious infection grown up. On the base of 13 fungicide active ingredients and dosages by two spraying applications, their efficacy could be evaluated in stripe rust control. Picoxystrobin 250 g/L acive ingredient applied in 0.6, 0.8 and 1 L/ha dosages (Acanto), picoxystrobin 200 g/L + ciproconazole 80 g/L combined active ingredients in 0.5, 0.75, and 1 L/ha dosages (Acanto Plus), epoxiconazole 83 g/L, moreover protioconazole 125 g/L + tebuconazole 125 g/L combinations gave good efficacy, respectively. The yield of well protected plots were 5 to 8 t/ha, but the losses were 40-70% when fungicides with no sufficient efficacy in stripe rust control were applied. The great infection, which was observed on different grasses late in the Autumn, 2014 might forecast a further stripe rust epidemic for the 2015 year.

    Long-term experiments are required to evaluate the impact of irrigation, nutrient utilization, and year factor as well as to assess the potential consequences of climate change. However, in the long-term experiment, it may be necessary to display spatial data for each parcel, either for investigation of soil heterogeneity or presentation. This article aims to provide help for researchers working in long-term experiments for storing and displaying spatial data.

    After the outlines of each experimental site were measured with GPS, a spatial database has been created in Quantum GIS. Then, a filter script in R statistical environment using RStudio graphical interface was written. The script helps avoid the QGIS data input interface so that large data can be attached to each parcel directly and as a result there is no need for a separate data entry, only the basic statistical database.

    The created GIS database can be used in many ways; it can be exported to KML file format that can be displayed using Google Earth. It is possible to view exported KML files in Google Drive with importing them to Google My Maps application, and with that a browser can display the map. With the Google Drive the maps can be shared within the research group, additionally the outlines can be edited and it is possible to upload the measurement data to the attributes table to existing empty table columns. The map created in Quantum GIS can be used for presentation purposes.

    This review examines the significance of live feeds in commercial aquaculture industry for production of fish and shrimp larvae, along with various challenges and prospects. Live feeds are an essential food source in larviculture, especially for marine fish, which depend on them for nutrition during the initial days of exogenous feeding. They are palatable, highly digestible, and their movement stimulates natural hunting and foraging instincts, promoting better development, lowering captivity stress, and increasing survival rates. Artemia is the most commonly used live feed in larviculture; however, it has low levels of omega-3 HUFA. Copepods are the most nutritionally rich live feed, containing high levels of DHA and EPA. Despite these benefits, they are less frequently used in larviculture due to technical challenges associated with large-scale cultivation at high densities. The use of live feed is labour-intensive and costly. The feeding period for fish larvae can be shortened using a co-feeding strategy. Microalgae rich in DHA have been utilized to enrich live feeds. Further research is needed to determine the most effective approach to significantly reduce the weaning time of fish larvae from live feed. This will lead to gradual and eventual complete replacement of life feed in the near future.

    There are many literature sources focusing on the phytoremediation of woody plants, but there are only few dealing with the phytoremediation of bamboo plants. Phytoremediation technology has the advantages of little disturbance to the environment and low remediation cost. Bamboo mainly exists in tropical and subtropical regions. As an energy plant, bamboo has a fast growth cycle, large biomass, simple cultivation, high economic efficiency, and convenient harvesting, which highlights the advantages of bamboo in phytoremediation. In addition, bamboo plants have good tolerance and uptake ability to heavy metals and have high application potential and development value in uptaking heavy metal contaminated soil. However, due to climate, temperature and other reasons, bamboo cannot be widely planted in most countries. Research status of remediation of heavy metal contaminated soil by bamboo plants is summarized. The feasibility of its application in heavy metal contaminated soil is discussed in this paper. Aiming at the shortcomings of existing research, bamboo plants have a prospect in the field of plant phytoremediation for the future.

  • Development of the antioxidant indexes (FRAP, TFC, TPC) of scabbing resistant apple varieties in storage

    One of the most important groups of bioactive substances in apples are antioxidants, which have a health-preserving effect. The amount of these compounds varies not only during the ripening of the apple fruit, but also continuously during post-harvest storage. A growing group of health-conscious consumers are looking for apple varieties with a nutritional value that satisfies their needs.

    In the scope of our research, we examined 5 apple varieties originating from the Derecske horticultural site of KITE cPlc. in 2016. The plantation was planted to be suitable for intensive apple production. Samples were collected at the time of maturity (August-October) of the given variety. The 5 examined apple varieties (Gaia, Isaaq, Modí, Smeralda and Fujion) are all resistant to apple scab (fungal disease caused by Venturia inaequalis). The 2-month storage experiment was conducted at 16–17 °C, which had an aggressive effect on our stored apples. Total polyphenol (TPC) and flavonoid (TFC) content as well as FRAP values of the apples were measured. Measurements were taken immediately after harvest and after 1 and 2 months of storage. Our results were evaluated by using the IBM SPSS Statistics 20 software. Our aim was to compare the antioxidant results of 5 scab-resistant apple varieties, which change continuously during storage.

    The antioxidant content of our apple varieties increased during 2 months storage. The best result was achieved by the Modí apple variety (FRAP: 467.32 mg/100g; TFC: 317.76 mg/100g; TPC: 1771.97 mg/100g). Consumers may want to consume apples stored for a longer period of time if they are to absorb large amounts of antioxidants.

    The main objective of this paper is to give an overview about the economic results and financial status of agricultural enterprises in Hajdu-Bihar Count, as well as, froa methodology viewpoint,find the place of the used indexes in the system of effectivity indexes in farm management . From the complex database describing the enterprises, the figures on the balance sheets and profit and loss accounts were used and analysed. As a result of the analysis the below statements can be made:
    The owner’s equity ratio within the total equity is very different in corporations and in individual farms. The lower values in case of corporations show their indebtedness. At the same time, the figures indicate that it is more difficult for individual farms to receive loans.
    The average of dynamic indebtedness indexes, in case of individuals are closer to 0 which generally derives from the low level of liabilities. The same indexes of corporations o the other hand show significant indebtedness. The figures indicate that the yearly cash flow can hardly cover the net liabilities.
    The profitability proportional to the production value is generally low, mostly negative, independent from size and organisational form.
    As a summary, it can be said, that individual as well as corporate farms suffer financing problems, the nature of these problems is different in the two groups. On the on hand, the operation and development of the individual, mostly the smaller, farms are hindered by the difficulties of acquiring external capital. On the other hand, the results of corporate, mostly the cooperative, farms is impeded by the burdens of liabilities accumulated in previous years.

    Hungarian agriculture may be characterized by the industry-like, conventional farming of the past decades. This form of management concentrated exclusively on functions aimed at production. We have to decrease this disproportion, especially when joining to the EU, by reducing the intensive agricultural regions and adjusting to the goals of the 2000-2006 NAEP programmes, forming such an agricultural system which integrates the advantages of both environmental protection and complex agricultural systems based on rational foundations. Nevertheless it’s a rational decision to make the soil information system with an exact spatial informatics background as a foundation of agricultural system, because this promotes easy handling as well the connection to possible subsequent modules.

    In 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.

    The Debrecen International Airport in commercial means might be the eastern gate of the European Union. This statement is in question these days .In the neighbouring countries like Slovakia, and Romania the old commercial airports have came through major renovation, and technical improvement. With Romania joining to the Schengen Agreement, Debrecen is going to lose its comparative advantage. So, it is time to follow up what has remained from the five years ago still existing technical and commercial priority of Debrecen aerodrome. In this study looking through the technical background of Kosice, Arad, Cluj-Napoca, Targu-Mures, Oradea, Baia-Mare, Satu-Mare, and Debrecen international airports we have found that Satu-Mare, Arad, and Targu-Mures might be major competitors af Debrecen airport. The level of installed technology has exceeded the one in Debrecen in case of Targu-Mures, and Arad. The situation is the same in Kosice which the absolute market leader in the region.
