  • System of relations between competitiveness and social cohesion in the European Union (2007–2020)

    I my current essay I tried to prove that the European Union modified its economic policy due to the financial and economic crisis and the fierce global competitiveness requirements. The main emphasis was laid on the increase of competitiveness. Competitiveness became preferred
    to cohesion and the economic and social closing up of the newly joined Middle-Eastern European countries. The funds for competitiveness for growth and employment increase by 6–7% yearly during the financial perspective between 2007–2013. On the contrary the funds for agriculture and rural development decrease by 3% yearly in this period. The tendency remains unchanged during the financial perspective 2014–2020.
    This tendency strengthens the establishment of the two speed Europe concept and causes tensions between the core regions and the peripheries.

    This study presents the yield results of some French bean varieties in organic and conventional farming. This study presents the advantage of organic farming in environmental point of view and in nutrition. Sale of organic products is insured, there is solvent demand rather in abroad than in Hungary.
    In Research Centre of Nyíregyháza had made organic farming since 1994, at present on 74 hectares.
    In the first trial, variety comparison with 9 yellow podded French beans in organic and conventional farming was conducted. Varieties: Carson, Cherokee, Debreceni sárga, Goldmine, Héliosz, Minidor, Sonesta, Sundance és Unidor. The following parameters were observed: the time of emergence and flowering, number of plants per plot, plant height and flowing green harvest. We weighed yield of the standardized, un-standardized and diseased pod fractions. The results were evaluated statistically with SPSS and Excell softwares.
    Emergence had all at once, but the plants of organic farming were 5 days earlier at flowering and maturity, than conventional farming.
    The plants in organic place were more developed than in conventional ones. Emergence was more uniform, the growth and the number of plant were square. Significant difference was not detected in plant height between two places. Most of the varieties examined had better total yield in organic place, than in conventional ones. Deviation depended on variety. ‘Sonesta’ and ‘Debreceni sárga’ had the best yield in both places. In
    conventional farming choice can be expanded with ‘Unidor’ and ‘Sundance’. In organic farming choice can be expanded with ‘Minidor’ and ‘Carson’.
    In both places the Sonesta, Debreceni sárga and Unidor varieties had the most standardized yield per hectare. In organic place Carson variety had good pod yield because it was infected less by diseases.
    In the another trial we studied inside content values of some varieties on organic and conventional places. The parameters were observed: dry matter-, starch-, crude fibre-, crude protein content and amino acid content.
    The rates of asparagin or glutamine acid were the highest, which was followed by serin or histidine. In asparagin content was the most deviation between conventional and organic farming.
    Significant differences were between varieties in dry matter-, starch-, crude fibre-, and crude protein content both on organic and conventional places. Each variety had significant differences between organic and conventional farming.
    Starch had strong and negative correlation with dry matter, crude fibre and crude protein content.
    Budai piaci and Minidor varieties and BU-16 variety candidate had higher starch content and lower dry matter, crude fibre and crude protein content on organic place. Sonesta variety had almost equal dry matter content on both places, but crude protein content was higher with 10% and starch content was lower with 6% on organic place, than on conventional place. Paridor variety had almost equal starch content, but it had higher dry matter and crude protein content on organic place. 

  • Changes in toxic elements content of soil after sewage sludge treatment in energy willow plantation

    The primary purpose of our experiment was the solution of municipal excess sludge treatment by a renewable energy resource used willow (Salix viminalis L.) plantation. Tests were carried out to state whether the applied sewage sludge has caused any accumulation of the toxic elements in the studied soil layers, and - based on the results –to see whether the plantation is suitable for the treatment of municipal sewage sludge.
    The excess sludge (sludge before dewatering) is beneficial for the willow, because it contains a 3–5% dry matter and therefore, a lot of water, too. This high water content ensures the high water amount needed for the intensive growth of the willow. On the other hand, the wastewater treatment plant can save the dewatering cost which corresponds to about 30% of the water treatment process costs. The amounts of the sprinkled sewage sludge were calculated on the basis of its total nitrogen content. Treatments were the followings: control, 170 N kg ha-1 year-1 and 250 N kg ha-1 year-1. The mean values of the toxic element concentrations in the sewage sludge did not cross the permitted limits of the land  accommodating.

    The measured toxic element values of the soil were compared to the limits of the 50/2001. (IV.3.) Government Regulation.The  sprinkled sewage sludge on the bases of the total N content did not cause accumulation of heavy metals in the soil and the treated plants were also healthy without any signs of toxicity. 

  • The effect of the dates of shoot selection and shoot tip removal on the growth of William’s pear trees

    Increasing the intensity of production in the case of pear can be the solution to satisfy the market demand forr high-quality fruit. The aims in this technology are the canopy treatments and the maintainance of consistently high quality yields in the long run. The experiments were performed with cv. William’s pear, a cultivar grown on large areas in Hungary. To create the optimal canopy shape for earlier fruiting, we performed shoot selection and the cutting back of shoot tips. Our results show, that both pruning methods – applied at 3 different dates – decreased the number of short fruiting parts (spurs), and increased the number of vegetative shoots. The sole exception was from this the effect of shoot tip removal when done at the earliest date.

  • Water managed properties of apple and pear trees based on lysimeters

    A significant proportion of the aboveground green and dry weight of the plant is constituted by foliage. The canopy is an important factor of plant growth. On the one hand, the canopy absorbs solar energy, which is necessary for photosynthesis; on the other hand, it accumulates the nutrients absorbed by the roots, and most of the water-loss occurs through the foliage. The determination of the full canopy is not an easy target. In our research, we developed a measurement method to determine the leaf area. With the parameters of the examined tree (leaf length and maximum width) and the data of the ADC AM 100 leaf area scanner, we determined the k-value, with which we can easily and fast evaluate the leaf surface. Furthermore, we defined from the water balance of compensation lysimeters the cumulative transpiration of fruit trees and the efficiency of water use of trees. From the examined trees were made a 3D depiction, which show the shape, branching and the location of trees.

  • Allelopathic effects of water extracts of pieces of wooly cupgrass (Eriochloa villosa) on the seedlings of field crops

    In Hungary, the woolly cupgrass (Eriochloa villosa [Thunb.] Kunth) endanger row crops (i.e. corn, sunflower). Its fast spreading based on some reason viz. long-lasting emergence, reduced sensitivity to many kinds of herbicides, vigorous competitional ability and fast initial growth. Allelopathy, ability of many plant species to produce one or more biochemicals wgich is used tocompete with each others. In this experiment we examined, whether the woolly cupgrass possesses allelopathy, and if so, how influences on the development of cultured crops like maize, sunflower and lettuce.
