    Mid-term evaluation of grant programmes always aims to assess the efficiency of programme implementation. An important aspect of assessing efficiency is the lead times of the application mechanisms. A detailed and objective analysis of lead times may set the scenes for an in-depth evaluation of the relevant entities in the application process in terms of capacity,competences or the process itself. The Bulgarian regional operational programme (OPRD) and the Maltese ESF operational programme (OPII) mid-term evaluations offer an opportunity to see application of this method on the ground with a view on results and comparisons. This article attempts to provide an overview on lead time analysis, being a simple but powerful tool for evaluation with great benefits and also great potential pitfalls in terms of use and interpretation.

    Prunig is a key element of fruit production technology and is affected by a number of subjective factors. Putting research findings into practice is often hindered by bad and harmful habits that make plantations and trees heterogenious in terms of growth and fruiting features, which can even lead to significant financial losses. Having identified this challenge, in this publication we aim to present some guidelines for those who are open to new ways and believe in the power of innovation. The 21st century is undoubtedly the century of unstoppable IT innovations filtering through into our everyday lives. The fact that our project is based on IT innovations is not only essential due to the subject matter itself but also because it makes it easier to address younger generations. Whichever tool they choose to use (smartphone, tablet, laptop), all registered students have access to our web contents, making it super easy for them to practice pruning techniques. Students don’t just read texts in our training materials but have access to a pool of pictures and images to illustrate the different procecces and phenomena. All the different phrases have explanations against them, so anyone can understand the ins and outs of why and how to prune or remove the different crown parts (5-year-old and above crown parts, 2–4-year old parts or 1-year-old parts) to achieve specific results, whether it be apple, pear or cherry trees etc. Our database comprises thousands of pictures that will walk you through the entire fruit tree pruning process, without you even having to leave your desk. There is an old proverb that also applies to pruning: „The wise man learns from the mistakes of others, the fool has to learn from his own”. Our program aims to help students by presenting a number of bad examples along with their corrections as well as photos of ideal ways to prune multiple different crown shapes. Using our web-based tool eliminates time and space limitations, i.e. you can access our interactive contents to gain or extend your pruning skills, irrespective of the pruning time and location.

    In the sport- life of the University of Debrecen there has been a demand formulated on the making of a comprehensive, long-term development plan, which obviously incorporates all
    fields of sport. This document guides the way for people in the sport- life of the university how they could organise their activities connected with sport on a calculable, predictable level.
    Necessarily, the preliminary collection of professional informations has been a basic requirement for the establishment of this document.
    The program provides foreseeable instructions to the organisation of sport pursuits both for sport people in the university, and members of the sport spehere in a wider sense. It
    offers a cohesive solution for all kinds of tasks defined with the sport life, and also gives a guidance for the various ways of realisations of these challenges. Thus it can answer such questions as for example how the university can conduce the initation of conditions for the healthy living through spare time sporting, how it can participate in the financing of contest sport with the contributing project of reinforcement training and how the university can support the sport life of handicapped people. The project also contributes to the cultivation of the sport traditions of the university by bankrolling not only the official university sport
    life but also the leisure time sporting of the students.
    On the basis of rethinking the situation of sport at the university with its future possibilities the program paraphrases the tasks of the university in the sport life, the long term aims of
    university sport politics with its operative aims that should be performed and also the possible steps which lead to these purposes.
    The target of the project is to turn the University of Debrcen in every field into a “Sporting University”. It means, that beyond the development of quality sport and outstanding contest sport a much wider range of university people should be included in sporting in order to utilize all the advantages of sport. With this the physical culture could become not only a substantial form of spending our free time, but with getting one of our natural everyday activities it can also become our lifestyle.
    Sporting prominently contributes to both the university students’s and the whole society’s mental and physical wellfare, and it also helps to improve our helthstate on various fields of life:
    with its special functions it is a means for establishing a healthy nation, for promoting common relationships, for nourishing the economic activity of people and also for strengthening the national values and one’s self-esteem through providing equal opportunities.
    The prosperousity of contest sport at the university and the maintaining and protesing of its efficiency fortifies our selfregard, as it is able to hold appropriate sportsmen up as examples
    to both present and future universtity students, and also offers exacting ways of entertainment. Besides all these the advataged purpose of the project is to find and delibaretaly include those
    necessary mechanisms which are needed for the working of the sport market.

  • 75 years of the chestnut blight fungus Cryphonectria parasitica (Murr.) Barr in Europe

    The chestnut blight fungus Cryphonectria parasitica is a native pathogen in East Asia and has been introduced into North America and Europe. Historical records and population genetic studies revealed at least three major introduction events from Asia into Europe.

    Nowadays, chestnut blight is present in almost the entire distribution range of European chestnut, i.e. from the Iberian Peninsula to the Caucasus. The C. parasitica population in most countries has been studied in respect to the diversity of vegetative compatibility (vc) types and the occurrence of hypovirulence. The vc type diversity of the different populations varied considerably. Typically, a high diversity of vc types has been found in areas with a long history of chestnut blight and where sexual recombination between divergent genotypes commonly has occurred. On the other hand, newly established populations often showed a low diversity with only one, or a few vc types present.

    Hypovirulence, i.e. the occurrence of C. parasitica isolates infected by Cryphonectria hypovirus 1 has been found widespread in Europe. Natural dissemination and active biological control applications have lead to a high prevalence of the hypovirus and to the recovery of many chestnut stands. Virulent cankers became hypovirus-infected within a short time and ceased expansion. There is concern that the diversity of vegetative compatibility types could increase in Europe through sexual reproduction between C. parasitica genotypes originating from different introductions. A higher level of vegetative incompatibility would not only hamper hypovirus spread within a population but could also select for lower virulence in CHV-1 and subsequently lead to an erosion of biological control. Recent studies, however, indicate that the vc type barriers are not so restrictive than previously assumed and that so far no evidence for an erosion of biological control system in high diversity populations can be observed.

  • Theoretical schools on employment and workforce

    In the civil economics, like in the case of any other socialeconomic issues, there are two coexistent theories concerning employment. On one hand we have the classical-neo-classical
    school based on Adam Smith’s works. On the other hand we have the teachings based on John Maynard Keynes’ views. All the later hypotheses are based on these two trends.
    Monetarism, which was invented at the beginning of the 20th century, mixes certain elements of both basic theories. Those who represent monetarism agree on rejecting the economy policy
    means which affect the processes of the workforce market, while they consider these above mentioned means applicable to regulate certain processes. By the end of the 1970s the neo-classical macro-economics had developed, which completely refuses these approaches. A decade later the neo-Keynesian macro-economics developed. Its hypotheses regarding  especially employment and unemployment lead to some of the employment issues of globalism, which is one of the most influential phenomena of present time.

  • Evaluation of reduced tillage technologies in corn production based on soil and crop analyses

    Despite new cultivation methods, the proportion of conventionally cultivated land is still very high in Hungary.
    Although these technologies demand more time, labour and fuel, they are still attractive to users because they require less professional skill and simple machinery. In Hungary, conventional tillage methods usually lead to soil deterioration, soil compaction and a decrease in organic content. These side effects have caused gradually strengthening economic and environmental problems.
    The technologies for those plants which are dominant on Hungarian arable lands use (winter wheat, maize, sunflower and barley) need to be improved both in the interest of environmental protection and the reduction of cultivation costs.
    The Department of Land Use at Debrecen University is cooperating with KITE Sc. to carry out soil tillage  experiments at two pilot locations to prove tillage technologies already used in the USA.
    The aim of our examination is to adapt new technological developments and machinery, and to improve them on Hungarian soil for local environmental conditions. With these improved machines, the field growing of plants could be executed by less manipulation and better suited to economic and environmental needs. The most significant task is to investigate and improve the conventional cultivation replacing, new soil-protecting tillage technologies, and to apply no-till and mulch tillage systems.
    On the basis of the experiments’ survey data, we established that the looseness and moisture content of the soil using reduced tillage is more favourable than after using conventional technologies. The results of no-till and shallow spring tillage are behind those of winter plough or disk ripper cultivation in corn yield and production elements.
    To preserve moisture content in the soil, the ground clearing and sowing while simultaneously performing no-till method presents the most favourable results. The surplus moisture gained using no-till technology is equal to 40 mm precipitation.
    Regarding the yield of winter wheat we established that the tillage methods do not affect plant yield. Both disk ripper and conventional disc cultivation showed nearly the same harvest results (5.55 or 5.5 t/ha), where the difference is statistically hardly verifiable from the no-till method. From the individual production of corn and the number of plants planted in unit area,  calculated results prove that no significant difference can be detected between the production of winter plough and disk ripper technology. Although the yield achieved with the no-till method is less than with the previously mentioned technologies, the difference is only 9-10%. We received the lowest production at shallow spring tillage.
    Evaluations have shown a 1.1 t/ha (13%) difference in the yield of maize, between winter tillage and the disk ripper method, in this case the traditional method resulted in higher yield. In winter tillage, the yield of maize was 1.9-2.1 t/ha (23-25%) higher than in the case of direct sowing and cultivator treatments. No significant difference could be noted between the yields of direct sowing and cultivator treatments.
    Our research so far has proved the industrial application of reduced tillage methods in crop cultivation technologies.

  • Changes in the Diaporthe helianthi Infection of Sunflower Hybrids Between 1998 and 2002

    Plant protection, and especially the efficiency of protection against mycosis, is a very important production technological element concerning sunflower. The efficiency of production can be increased on the basis of a thorough pathological survey and its results carried out in a wide variety of hybrids, as the features of hybrids, the reactions of genetic bases to pathogens can be found out under domestic conditions.
    The tests were carried out at variety-test lots of OMMI for hybrids used for food or oil and other sunflower varieties admitted by the state at the Experimental Site DTTI Látókép, Centre of Agricultural Sciences, University of Debrecen between 1998 and 2002. The number of the tested hybrids was 49 in 1998, 45 in 1999, 49 in 2000, 55 in 2001, and 44 in 2002.
    Due to the infection source of high amounts remained from 1997 and the favourable weather conditions for the pathogens, an infection of high degree was experienced in the tested stands. The lowest infection index in the hybrids with a very short vegetative period was experienced with Beni hybrids. Comparing to the average of the hybridgroup with short vegetative period, a low infection index characterised the Baleno, Trident, IBH-166, Hysun 321, Resia, Alexandra, Cergold and Pixel hybrids. In 1999, among hybrids with medium vegetative period, Zoltán, Zsuzsa and Util hybrids could be highlighted because of their low infection index. In 1998, among confentionary hybrids, Marica-2 hybrid had the most favourable index values (2,55).
    During our trials, the experienced infection dynamics were compared in the event of hybrids with higher and lower susceptibility under different sowing technological elements. The results call for the fact that when a hybrid with higher susceptibility is produced, production technological elements, such as the time of sowing, influence considerably the damage caused by the pathogen, therefore it must not be ignored when its determination takes place. In the event of hybrids with lower susceptibility the change of the tested production technological elements within the biological optimum does not lead to the increased risk of the damage caused by Diaporthe helianthi.
