    In the recent decades it has become apparent that the human race can lead to a polluting and energy- wasting lifestyle and the depletion of natural resources and an ecological disaster as well.

    Energy efficiency is the realization of the chance to see a wider use of renewable energy. Renewable energy sources can be found in large quantities in Europe. A proper exploitation of these would be important because of the "traditional" energy sources’s sate is very critical in many ways.

    The utilization of renewable energy sources depends on many factors. The local natural conditions significantly determine each country's different renewable energy potentials. I find to be important the natural conditions, such as, solar radiation intensity , the number of sunny days per year, the wind conditions , the volume and their energy characteristics of the geothermal power resources , land features , soil and rock quality, the supply of fossil fuels or the nuclear possibilities of energy production. The economic environment is also a major influencing factor for the utilization of renewables. The conditions of price of fossil fuels (natural gas, oil and coal), the price of nuclear fuel production and other energy costs significantly influence the demand for renewables, as well as the level of subsidy and government tax policy. In addition, the international and national programs, objectives, strategies, subsidies and regulatory measures as well as technological factors can have a significant impact.

    In my paper I point out the opportunities of renewable energy should be given to live. Nowadays the positive effects of their use is undisputed. In addition to the environmentally friendly produced energy, we should strive for energy conservation and energy efficiency as well. These expectations appear in practice, which can be directly perceived by citizens, in fact we should live accordingly. Furthermore, the environmentally relevant regulations of living conditions should appear as environmental demands.

    The necessity of application of hybrid specific crop production technology has been confirmed not only by trial results but also by the experiences gained from the agricultural practice. For this reason it is essential to test and collect data in field trials about the specific agronomic traits of the corn hybrids belonging to different maturity groups and genotypes. Corn hybrids are tested for their responses to sowing time, plant density and fertilizer supply; sensitivity to herbicides; and lately, the resistance to the damages caused by the larvae of corn root worm. Last but not least, mention should be made of the differences in the responses of the corn hybrids to the damages caused by drought stress. Based on the trial results, suggestions for the hybrid specific corn production are compiled and made public for the experts and farmers engaged in corn growing. Corn hybrids may deliver maximum yields on the impact of specific crop production technology only in case if it relies on carefully done general production technology including soil cultivation, seed bed preparation and weed control. Similarly, precision crop production technology may advance the yield increase in economic way if it is constantly drawing on the source of research results.

  • Effect of facility location on haulage efficiency

    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.

  • Development directions of microregional spatial environments

    The question how economic, technological and infrastructural developments, as well as products and technologies contribute to the unity and constant strengthening of the society is still unanswered both in Europe and the whole world.

    The current erosion of the society and the weakening social cohesion is a regrettable process. These phenomena are a barrier to real development processes and weaken the extension of the economic space; therefore, this negative process has to be stopped and turned into a positive direction.

    For this reason, it is increasingly urgent to work out new, feasible solutions, since it has become obvious that solutions whose sole aim is to increase profit typically weaken the indispensable unity of the society, market positions, innovation processes, as well as natural and environmental harmony.

    In this situation, we analysed and interpreted the disadvantaged and multiply disadvantaged microregional spatial environments, with special regard to the strategic developments that serve both the strengthening of the microsocieties of microregional spaces and the development of the economy and the extension of economic space.

    The identification of disadvantaged microregional spaces is basically done by means of economic indexes, but it is also important to emphasise that these indexes can only be interpreted with social indexes, as they define the situation of the microregional space and the possible development directions together.

    The constant strengthening of social unity (cohesion) and the related economic development is basically a new focal point and objective.
