Productivity of thinned black locust (Robinia pseudoacacia L.) stands in Hungary: case studies
181-186Views:135Black locust (Robinia pseudoacacia L.) is one of the most important introduced tree species in Hungary, covering more than 24% of the stocked area and providing approximately 20% of the country’s annual timber cut. Consequently, the research and development activities related to the improvement of the growing technology of black locust are also important, especially in mitigating the negative effects of climate change. The aim of this study was to quantify growth and yield, responses of even-aged 12–31–year–old black locust stand to thinning in Hungary. The study has proved that irrespective of the yield class, age and thinning intensity, thinning could not increase effectively the cumulative volume production. As percentage of the control it has changed between +0.6 and -8.4%. On the other hand, it could increase the stand value based on stem quality index by 10–21%.

Harmonic development and biodiesel
91-95Views:119An increased expansion of renewable resources and biodiesel is observed and prognosed, since fossile energy resources are about to run out. Hungary achieved outstanding sunflower years in the recent years in worldwide comparison. In the future, the feedstock of biodiesel production can also be rape besides sunflower.
According to the concept of harmonious development, the balance between nature, society, economy and human environments is represented by their mutual presumptive character. Research and development need to be aligned into this system. Our aim was to examine the advantages and
disadvantages of biodiesel production in different environments, using a model to do so. In order to maintain the harmony, the existing resources have to be managed properly, taking the correlations of the system into consideration. Targeted technological developments are necessary, similarly to the improvement of energy safety and efficiency. -
Food Safety in EU Higher Education
188-197Views:87Under the aegis of the Lisbon Strategy, special attention is paid to education and areas left untouched by the European integration process. Human capital and research inputs were identified as major driving forces for long-term development. The European Union is keen on meeting its target of boosting research spending to 3% of GDP by 2010. In order to contribute towards his goal, the European Commission has set aside an amount
which is double the budget of the 7th Framework Programme. Accordingly, preferences were given to research and development projects encouraging competitiveness in the food industry and other initiatives, such as the European Technology Platforms. Major obstacles to innovation in Hungary are: lack of funds, weakness of research network, poor structural relations. Better utilization of our comparative advantages should be targeted in order to have the Hungarian food industry become a driving force sector. This is to be promoted by the newly transformed food
engineer training (as a result of the Bologna Declaration) which can adapt better to the changing requirements of the labour market. Food science and related research could become determining factors for the food economy by setting up accredited training systems and enhancing food safety education and training in Hungary. -
Study regarding the influence of the nPK fertilizers use in long term trial on heavy metals concentration in wheat grains
107-109Views:125The 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.

The influence of the fertilizing system on the petroleum residues biodegradation on a preluvosoil under control polluted
251-254Views:94The paper presents the partial results of researches regarding the agrochemical melioration of soils under control polluted by petroleum residues that took place at the Agricultural and Research and Development Station in Oradea, Bihor County.
The experimental device was made out of 1 m2 microparcels, spread out in subdivided parcels, in four repetitions, having tree factors: A - the pollution by crude oil from Suplacu de Barcău, B – the mineral fertilization, and C – the organic fertilization.
The experience was set out on a preluvosoil în the year 1993 and the soil was cultivated with millet in the first 3 years and with spring wheat in the last 7 years of research.
The researches carried out in Oradea had the objective of establishing the effects of the fertilizing system on the petroleum residue biodegradation on a preluvosoil under control polluted with crude oil from Suplacu de Barcău, Bihor County. -
Need for measurement of the innovation at Hungarian SMEs
5-13Views:149Competitiveness studies have shown that innovation could be breakout point for some economies, regions and enterprises. Knowledge acquisition, creation and exploitation of the knowledge base have been an essential element for economic growth. These knowledge-based economic processes come together with the innovation. Measurement of innovation by indicators has been playing a really emphatic role in making strategy whether it is national or EU planning.
Enterprises have always tried to measure and quantify their innovation activities mostly through the results of their economic process. Companies have generally considered their products as part of the innovation. That was the reason that in most cases they only and exclusively focused on the finished product. Some of them was able to realize that details of the production process must be taken into account in order to the whole innovation activity could be measured.
That is why I find it important to examine of what the innovativity of enterprises is made of, and in which way they can be measured.
In addition I was looking for the answer to the questions that how much the measuring method allows you to compare enterprises for further examination.The development of measurement methods is an essential moment of the article. As it is compiled for me the most important aspect of innovation, according to the statistical document, the Oslo manual guides you through the measurement methods and operational processes They play a very important role in proving my hypothesis. Overall, our country’s innovation results show those areas where we have high endowments, and also those where are the weaknesses.
Of course, systems and tools defined by the governing authorities of national economies will have the main role but the activity of the European Union will be the frame in the end, because without subsidies from the EU budget, national budget wouldn’t be enough to implement these aims.
