The effect of sowing time on the yield and the variance of the seed moisture content a harvest of maize (Zea mays L.) hybrids
39-49Views:473Sowing time is an important crop technology element of maize. We studied the effect of this factor on the growth and production of maize in an experiment carried out near Hajdúböszörmény, in 2003 and 2004, and near Debrecen, in 2005.
The soils of the experiments were humic gley soil and chernozem. Weather in both years differed greatly. 2003 was drought. Neither the distribution, nor the quantity of the precipitation were suitable in the growing season for maize. This fact basically determined the results.
In 2004 and in 2005, there were favorable and rainy seasons. The distribution and quantity of precipitation were suitable between April and September. The average temperature was also suitable for maize.
In 2003, we tested seven hybrids at four sowing times. Hybrids with a shorter vegetation period gave the highest yield at the later sowing time, while the hybrids with a longer vegetation period gave them at the earlier sowing time. The yield of PR34B97, PR36N70, PR36M53 hybrids were the best at every sowing times. The moisture loss of hybrids in the late maturity group was faster in the maturity season, but the seed moisture content was higher than the hybrids with early sowing time. The seed moisture content was very low due to the droughty year. In two hybrid cases, this value was higher than 20% only at the fourth sowing time.
In 2004, we examined the yield and seed moisture contents of nine hybrids. In the favorable crop year, the yield of every hybrid was the highest at the second and third sowing times. Yields of PR34H31 and PR38B85 hybrids were significant. The seed moisture content at harvest was higher than the previous year, due to the rainy season. In the case of hybrids sown later, this value was higher by 30%. However, we noticed that this value was lower at the earlier sowing time, than at the later.
In 2005, we applied three sowing times. Unfortunately, the results of the third sowing time could not be analyzed, due to the low plant density. The yield of the six hybrids varied from 12 to 14 t/ha at the first sowing time. At the second sowing time, the yields fluctuated and each hybrid had the lowest yield, except the PR37D25 hybrid. At the latest sowing time, the yield of the PR34B97 hybrid was the lowest. However, this low yield was due to damage from the Western corn rootworm (Diabrotica virgifera) imago. The moisture content at harvest of the hybrids varied from 16 to 24% at the first sowing time. Yields at the second sowing time were higher. The low yield of the PR34B97 hybrid coupled with a higher seed moisture content. In addition, the maximum value of the LAI was more favourable at the first sowing time, and ranged between 5-5.5 m2/m2.
The crop year had a more dynamic effect on maize than the sowing time. First of all, the quantity and distribution of precipitation played an important role in respect to yield safety. -
Investigation of directions of crossing in maize (Zea mays L.)
43-48Views:333In Hungary, we examined eight features of twelve direct cross hybrids over a period of three years. The twelve hybrids were derived from direct and reciprocal crosses of four parental lines. We did not find significant differences in the cases of stalk diameter and leaf number in the average of 3 years in any of the hybrids. Statistically explainable differences in primary branches were observed in hybrids UDH5 and UDH8 and also in UDH6 and UDH11. It was evident in both instances that degrees of heterosis in reciprocal crosses far exceeded those of direct ones. High tassel branch number was dominant over the low one; consequently, parents with higher tassel numbers enforced their effects during the formation of this trait in hybrids. We experienced positive correlation (r=0.67**) between plant height and main ear height. A positive correlation (r=0.89**) was also found between the tassel length of the main axis above the lowest and the upper side branch. We observed a medium correlation (r=-0.42**) between the number of primary lateral branches and plant height. The number of primary lateral branches showed the highest heterosis. These results can be utilized in practical selection and seed production.

Plant growth analysis of wheat populations in a long-term field-experiment
147-151Views:528The experiments were conducted as part of the long-term trial adjusted, in triculture (pea-wheat-corn) and biculture (wheat-corn), at three nutrition levels, with the use of one crop protection technologie (conventional) at the Látókép Research Site of the Centre of Agricultural Scienses, University of Debrecen, on a chernozem soil. The wheat variety used in the long-term trial was GK Csillag, which was sown at 5,8 million germs/ha.
The effect of pre-crops and nutrient-supply levels on some growth-parameters (LAI, HI, LAD), just as SPAD-values and yield amounts of winter wheat has been investigated in this experiment. We tried to find out the extent of relationship between the different parameters, so we determined the relationships between different nutrient-supply levels, yield amounts, LAI- SPAD- and LAD-values – measured in the crop-year of 2010–2011 in different crop rotation systems – by using correlation analysis. It has been stated both in case of bi- and tri-culture crop-rotation systems that different fertilizer dosages had significantly affected the leaf area index dynamics and its maximal value, and that increasing N+PK fertilization has
significantly increased the duration of leaves, as well. The highest SPAD-values were measured during the flowering and grain filling stages. However, we haven’t revealed significant differences between all fertilizer treatments. In case of the bi-culture crop-rotation system harvest index values showed an increasing tendency parallel to the increasing nutrient-supply levels, while in case of the tri-culture system this tendency was rather decreasing. However, these differences were
not significant. Parallel to the increasing fertilizer dosages yield results were increased in a significant extent. At the same nutrient supply-levels 2088–4615 kg ha-1 higher yields were measured in the tri-culture than in the bi-culture system. The correlation analyses have confirmed that all of the investigated parameters (yield amount, LAI, SPAD, LAD) had almost in all cases close positive correlation to the nutrient-supply level and the yield amount in both crop-rotation systems. These results have confirmed that the leaf area, the leaf duration, the SPAD-values and the fertilization have altogether resulted in the production of maximum grain yields. -
The effect of NPK treatments on the Cu and Fe content of winter wheat (Triticum aestivum L.)
31-34Views:621In this study the effect of N, P and K nutrients on the Cu and Fe content of winter wheat (Triticum aestivum L.) grains was investigated in a long-term fertilization experiment set up in Nagyhörcsök. Samples were also harvested from four experimental stations of the Hungarian national long-term fertilization trials. These are the following: Bicsérd, Iregszemcse, Karcag, and Putnok. Plant samples were collected in 2005 which was very wet. Our results from Nagyhörcsök were compared with the Cu and Fe content of samples which were harvested from control plots of other experimental stations. The Cu and Fe content of grain samples were measured using inductively coupled plasma mass spectrometer (ICP-MS) followed by digestion with HNO3-H2O2 solution. All data were subjected to ANOVA, and when significant differences (P<0.05) were detected, Duncan’s test was performed to allow separation of means.
The main conclusions are as follows: Cu and Fe content of wheat grains was higher and higher in every NPK treatments. Samples were harvested from the control plots of Iregszemcse and Bicsérd have higher Cu content than the treated samples from Nagyhörcsök.

Previous data on the relationship between the intensity of pruning and the degree of damage in integrated and organic applegrowing systems
47-52Views:336In Hungary, fruit growers are increasingly interested in environmentally friendly growing methods, such as organic and integrated systems. Vital is the establishment of a strengthened system of cultivar-pruning-plant protection in production technology. Consequently, our aim was to examine the susceptibility of apple cultivars to diseases and pests and the effect of pruning technique on diseases and pests in organic and integrated growing systems.
Two pathogens (Venturia inaequalis, Podosphaera leucotricha) and two pests (Leucoptera malifoliella, Pannonychus ulmi) were observed in organic and integrated systems under „strong” and „weak” pruning techniques. Our results on six cultivars showed that the pathogens and pests infested the trees more in the organic system, as compared to that of integrated production. The pruning technique affected mainly the susceptible
cultivars to diseases and pests. The „weak” pruning technique caused a higher level of diseases and pests infestations than the „strong” pruning technique, especially in the organic growing system. The likely reason is that the shoots grow fast and powerfully under “strong” pruning technique. This supports better preservation of the trees supported by susceptibility of plant tissues to diseases and pests. -
A szervetlen-C és a szerves-C mennyiségének változása egy homoktalajban, meszezés hatására
8-10Views:376The effect of liming on different organic and inorganic carbon forms in soil was studied in a pot experiment on acidic sandy soil (pH(H2O)=4.38; pH(KCl)=3.42). We used three kinds of liming doses (which were signed M1, M2, M3,). M1 was half of the M2 dose; M2 was the calculated lime dose and M3 was one and the half dose of M2. Lime (CaCO3) was mixed into the soil in powdery form. In addition to liming treatments, a uniform N, P and K treatment (1-1-1g N, P2O5 and K2O per pot) was given. Water supply was set up to 75% field water capacity of soil. Pots were watered daily. During the vegetation period soil and plant (oats; Avena sativa L.) samples were taken from each treatment three times (after 6-10-15 weeks). We determined inorganic- and total-C of the soil by Vario EL element analyser (based on dry combustion method) and calculated the organic-C.
The conclusions can be summarized as follows:
– Liming treatments had a significant positive effect on the soil-pH and caused quantitative change of different carbon forms of soil.
– Increasing tendency of liming doses caused more intensive changes in inorganic- and organic-C forms of soil.
– A significant correlations was found between the soil pH and the inorganic-C fraction of soil.
– A decreasing correlation was found between the vegetation period and the organic-C fraction. -
Accuracy of Location Identification by GPS and Possibilities for its Application in Agriculture
157-160Views:323A description of the design and operating principle of the GPS system and the explanation of key terms of telemetric and chronometric measurements is followed by several examples characteristic of the results of factors which may influence accuracy of the identification of geographic location by satellites. In addition, results of accuracy testing of absolute GPS measurements and improvements of accuracy experienced and attributable to the alteration of the periods used for establishing average values are highlighted. Furthermore, we examined certain practical possibilities for the use of GPS systems in agriculture, emphasizing the advantages hidden in the use of GIS-GPS integration, crop mapping, soil maps and gross produce maps, in the application of the VRT (Variable Rate Technology) and in combinations of the same.

The Presentation of Debrecen University’s Solar Energy Power Plant
259-263Views:247Energy plays an important role in everyday life and in the economy. The use of fossil energy sources greatly damages the environment. Besides this, the quantity of these energy sources is limited. Therefore, it is important to increase the share of renewable energy sources (solar, wind, water, biomass) in energy generation. Huge amounts of energy (1150-1300 kWh/m2) arrive at the earth from the sun, which utilized in passive and active ways. One of the active applications is photovoltaic current production, in the course of which electricity is produced directly with PV-Panels. This can be fed into the grid.

Impact of ammonium nitrate and Microbion UNC bacterial fertilizer on dry matter accumulation of ryegrass (Lolium perenne L.)
35-39Views:236Pot experiment was performed to investigate the effects of increasing NH4NO3 doses with or without Microbion UNC bacterial fertilizer
application on dry matter production of ryegrass (Lolium perenne L.). Experiment was set up on calcareous chernozem soil of Debrecen-Látókép and on humus sandy soil of Őrbottyán. The bi-factorial trials were arranged in a randomized complete block design with four replications. Grass was cut three times. Dry matter production was determined and the sum of biomass of cuts was calculated as cumulated dry weights. Analysis of variance was carried out on the data in order to provide a statistical comparison between the treatment means. The least significant difference (LSD5%) test was used to detect differences between means. On the basis of our results it can be concluded, that the dry weights of ryegrass cultivated on chernozem soil were higher than on sandy soil. With increasing nitrogen supply the dry matter production of grass significantly increased in both types of soils. In case of sandy soil the increasing effect was more expressed, but dry weights of this soil never reached the appropriate values of chernozem soil. Application of Microbion UNC had positive effect on dry matter production of ryegrass grown on both two types of soils but the effect was more expressed on chernozem soil. Finally it can be concluded that the increasing effect of NH4NO3 on biomass weights was more expressed in both types of soils, the biofertilizer application also increased the dry weights of plant in a small degree. -
Complex evaluation of agrotechnical factors in rape seed
59-63Views:249A polifactorial field trial with rape was carried out in the crop-years of 2007/2008 and 2008/2009 at the Látókép Research Centre of University of Debrecen, 15 km away from Debrecen. The soil type of the research area was a calcaric chernozem, with a levelled and homogeneous surface. Our investigations on the dynamics of lodging proved that rape can easily be lodged under unfavourable weather conditions, which results in a significant crop failure: In crop-year 2009 yields were 1.0-1.5 t ha-1 higher than in 2008, when the weather conditions were more unfavourable. In both crop-years the influence of sowing time on the crop yield of rape was examined in three soil cultivation systems, with ploughing, loosening or disking. Different sowing time influenced the yield of rape in both crop-years significantly. In the crop-year of 2007/2008 – due to mild winter – we got the highest yield in the first sowing time (at the end of August) with loosening (3930 kg ha-1) and disking (3727 kg ha-1), while in case of ploughing we experienced the highest yield (3770 kg ha-1) in the second sowing time. There were no significant differences between the first and second sowing time (the end of August and the beginning of September), and in the third sowing time (end of September) also a moderate crop failure (-6.7%) cold be obtained, due to the favourable weather in winter and the water supply of the crop-year 2007/2008. In 2008/2009 all the three cultivation systems showed the best yield-results in the second sowing time (ploughing: 4886 kg ha-1, loosening: 5186 kg ha-1, disking: 5090 kg ha-1), and the first sowing time hardly differed from this (-4.1%), while the late September sowing time resulted in a significant crop failure of -11.1%.

Comparative analisis of different canopy forms of sweet cherry cultivars
19-22Views:297The Hungarian sweet cherry production has been changed significantly in the last decades, which primarily resulted in growing intensity of the orchards. Due to the favourable selling prices of the sweet cherry many growers see good prospects in this fruit. One of the key questions of their success is the choice of the most proper canopy form according to the growing conditions, which facilities the efficient completion of annual technological operations.
In new orchards almost exclusively variations of spindle canopies are established, although many other crown forms are used all over the world. From the point of the domestic sweet cherry production it is indispensable to get information about these canopies, and compare with the prevailing crown forms with central axis.
In our experiment we compared free spindle and bush canopies in the Horticultural Experimental Farm of the University of Debrecen in 2013. According to our results it can be stated that the bush canopy can be described with more balanced growth, which makes easier to maintain the vegetative and generative balance. Another positive characteristic of the bush canopy is, that the height of the trees is smaller with 50% compared with the free spindle, which makes the pruning and the harvest easier.

Comparative study of honeys and herbhoneys quality paramertes
117-120Views:574Honey is one of the oldest known and consumed food. Besides the pleasant sweet taste it has been consumed because of the favorable health benefits. In addition to large number of honey plants there are many popular herbals which cannot serve as a nectar source. The herbhoney has been developed that consumers can joy the pleasant properties of herbals and honeys positive impact on the same product. In our research we compare the quality parameters of honeys and herbhoneys to each other and with the relevant regulation.

Factors affecting the efficiency of superovulation and embryo transfer. Season and hormonal background
73-76Views:736Success of the embryo transfer programs is affected by many factors (breed, type, season, treatment). We assume, that periferical blood level of some metabolic hormones (IGF-1, thyroid hormones, leptin, insulin) affects the success of superovulation and ET. According to our results, there is a
significant difference between the in and out of season periferial blood level of IGF-1 and insulin. Furthermore, decrease in the periferic blood levels of IGF-1 and insulin is less drastic in the pregnant recipients. -
Alternatives of the multiple use of Virginia mallow (Sida hermaphrodita L. Rusby) as a shrub-replacing mallow in the temperate climate zone
51-56Views:337In the seventies of the previous century, Dr. Zoltán Kováts set two directions in the research of mallows. One of the directions was the biotechnology of the mallow species and the other direction is using the mallow species as biomass material. In order to do this he brought mallow mother spawns of ornamental and biomass sorts from botanical gardens abroad and tested many of them, including the a Sida hermaphrodita kind. Fourty years later, for the second time this plant, known as the „energy mallow” got back to Hungary again, right into the sight of hungarian biomass business with the help of László Balogh and his associates using help from Poland. This genus got into the center of our research, because of it’s valuable attributes. The latest experiments are about using it as an energy plant, without examining genetic details. The plant grows up to more
than 3 meters, has high growing rate and produces big amount of green mass. We don’t have any hungarian data about whether the plant continues the sufficient growing rate or not, after cutting it back.
We have to explore the potentials in the Sida’s sublimation. The plant is mostly suitable for ornamental and energy utilization, so further sublimation should be aiming for these aspects. During my research period, we are willing to get to know these potentials and the best possible use of them. -
The impact of production methods and row orientation on carrot quality in the case of various cultivars
65-69Views:349Carrot is a wellknown and favoured, really important vegetable. Carrot’s cultivation is important, although its growing field has been reduced in last few years. The suitable cultivar and landstructure are essential to produce good quality carrot. The ridge cultivation is widely spread on plasted soils. At this type of cultivation relationship between line orientations and carrot quality is less studied. That is the reason we tried to examine in our experiment the relationship between ridge highness and line orientation (N-S and E-W) and carrot’s morphological features at different genotipes. The experimental was settled in the Experimental Garden of the University of Debrecen on limy chernozem soil by plain, raised bed and ridge cultivation in 2013. In the experiment we examined four longgrowing cultivars (Danvers 126, Fertődi vörös, Rekord, Chantenay). The sowing was at 24th April. The harvest was at 15th October, 2013. In the multi factorial (type of cultivation, line orientation, cultivar) experimental we explained the effect of treatments on carrot root shoulder diameter and root weight.
In our experiment we stated that line orientation had no significant effect on shoulder diameter at different cultivations. The only exception is Fertődi vörös which has reached the biggest shoulder diameter (5 cm <) at N-S direction on raised bed. By examining the carrot rootweight we stated that they were higher in raised bed and ridge cultivation than in plain cultivation with the exception of one cultivar (Chantenay). This carrot had found ideal environment for growing between each cultivation conditions. That is why we can state that if you grow carrot on plasted soil and there is no possibility to make a ridge, use short, tapered and rounded ending root type for successful growing.

Brief overview of the polymorphism analysis of genes affecting pig prolificacy (LEP, PRLP, ESR BF, EGF, FSH-β, H2A.Z)
5-10Views:520Researches are being performed around the world to increase swine prolificacy by using marker-assisted selection (MAS). The present study processes researches of polymorphism examinations on 7 genes. The result of the experiments showed that the leptin gene (LEP) prolactin receptor gene (PRLP), estrogen receptor gene (ESR), properdin B (BF) epidermal growth factor (EGF), follicle-stimulating beta gene (FSH-ß) and Z member of the H2A histon family gene (H2A.Z) and their alleles have a positive effect on reproductive characteristics of different swine breeds. In addition to this, leptin gene (LEP) influences the build, meat production and growth of body fat. Further studies are concerned with the polymorphism of an increasing number of genes, which enables a faster genetic development of swine breeding.

Virtual Soil Information Systems in the Bihar Subregion and at Tedej Corp
186-189Views:546After evaluating the sample sites’ soils and environmental status, we built up 2 different soil information systems. The first relies on analog data (soil maps), and is based on a regional model; its sample site is the Bihar sub-region. The second is a complex, field scale virtual 3D system, based on several types of data sources. (Aerial photos, GPS, field samples, hyper and multispectral images, soil maps). In this paper, we analyze and evaluate these systems. The greatest advantage of the models is that, with their usage, we can reveal connections which cannot be made by analyzing the individual elements of our data sources. We discovered that with the help of our systems, the monitoring and evaluating of the processes taking place in the soil is more fast and simple.

Self Pollination and Fruit Quality-Comparative Research of Sweet Cherry Cultivars
295-299Views:335In fruit production – among stone fruits – sweet cherry is considered to have great promise, but species of sweet cherry need improvement. Cherry plantations are advanced in years, therefore putting into operation high productivity plantations is an important field of research. Through clonal selection and cross-breeding, several new cherry species were created in the recent past in Hungary. Spread of these species is also important. In our factorial cherry production, we use high trunk trees and trees with large crowns. Intensive plantations are very few in number.
Our goal is to study the morphological and physiological properties of new sweet cherry cultivars. The most important aim is to combine the productive area of foliage and the fruit quality. The present study shows the self pollination, fruit setting and fruit quality parameters. -
Examination of repeatability of ultrasound scanning technique in young bulls
43-48Views:501The author’s goal with the methodology examination was to determine repeatability of taking and evaluating ultrasound images. In the trial an operator person took two images about the ribeye area and rump fat thickness (P8) of every young bull, which were measured by the same person in four repetitions. Also, we had altogether eight images about the same part of the body. Images were collected using Falco 100 (Pie Medical) real-time ultrasonic scanner equipped with an ASP 3,5 MHz, 18 cm linear array transducer.

Study of some physiologic properties of different genotype sweet corn hybrids
105-110Views:287The effect of nutrient-supply (control, N120+PK) and two different genotypes on the physiologic properties of sweet corn has been investigated in the crop-year of 2011 on chernozem soil in the Hajdúság region. The experiments were carried out at the Experimental Station of the University of Debrecen in Debrecen-Látókép. The experiment was sewn in two different sowing times: the 21st April can be considered as an early, while the 19th May as a late sowing time. The two involved hybrids were Jumbo and Enterprise. The applied plant density was 65 000 plants per hectare.
Our aim with this experiment was to study the plant production, just as the main affecting factors of its development and dynamics, like nutrient-supply and genotypes. We aimed to study and analyse the relationships between these factors and plant production. In this study following parameters were measured and calculated: photosynthetic activity, chlorophyll-content (SPAD-value), leaf area index (LAI) and leaf area duration (LAD). Regarding the analysis of photosynthetic activity values no obvious relationship between the measured values and the applied hybrids, just as nutrient-supply has been revealed.
Analysing the SPAD-values it can be stated that the chlorophyll-content of the measured leaves showed an increasing tendency due to the nutrient-supply. The highest values have been measured in the intensive cob development phase of the early sowing time plots.
Regarding the LAI-values we have found significant differences between the fertilizer treatments in both sowing time treatments. In case of the leaf area duration values – that is derived from the LAI values – nutrient-supply has positively affected the duration of the assimilation area. -
Anaerobe degradation of maize infected by Fusarium graminearum
57-61Views:663Last year intense rainfalls and moisture conditions were beneficial for the Fusarium sp. in Hungary. Fusarium strains decrease cereal quality (for example maize), furthermore may cause yield loss. Due to the toxin production, the fungi have a dangerous animal and human pathogen effect (Placinta et al., 1999).The effects of the Fusarium infection and its mycotoxin production haven’t been perfectly eliminated. Fusariumgraminearum
is the most common agricultural pathogen in Hungary. The utilization of infected maize as an alternative biogas raw material may be an efficient and environmentally friendly disposal method. In this case, Fusarium-, and mycotoxin-content of the maize have to be analyzed as well as the impact of these factors’ on the biogas production process. Our experience was based on the raw material basis of a biogas plant. Different amount of Fusarium free and infected maize grits have been added to the regular raw material mixture. The detection of Fusarium fungi has been analyzed
in experimental digesters throughout the different stages of mesophilic digestion. In the biogas liquid end product the Fusarium was detected by breeding and by microscope. According to our results, the Fusarium sp. was not detectable in the liquid end product after 30 days. -
Comparative study of different soybean genotypes in irrigation technology
91-95Views:864In many places in Hungary, early maturity soybean can be successfully grown. The earlier maturity group of soy which ripened in 110–125 days in most crop areas in Hungary. However, to achieve excellent results, the selection of proper varieties is important too. Successful cultivation is largely dependent on the macro and microclimate of the production area, the nutrient supply of the soil and the cultivation technology. Soybean can be produced in places where the amount of precipitation is right, as the lack of water results in lower yields and deteriorated oil and protein concentrations. In the following study, 2 years (2016 and 2017) are compared to the yield, protein and oil content of the soybeans of the early maturation group in irrigated and non-irrigated treatments. Based on our experiment, it can be stated that, during the irrigation of soybean, oil and protein content and yields did not always change.

Periphery formation and economic-social conflict
87-90Views:291The timeliness, significance and importance of the study is sensitively shown by the fact that a large part of the Tisza region is slowly being moved to the periphery in the slowly modernising and changing economic and settlement spatial structure of the Great Plain. This situation is also deepened by the fact that the social and economic backlog increases in the majority of the region, as one third of the 33 most disadvantaged small regions in Hungary can be found here. This study basically contributes to the establishment of the development of the Tisza river’s spatial environment and the development of new solutions.

Pest species of Macrolepidoptera in the Game Reserve of Velyka Dobron’ (Transcarpathia, Ukraine)
58-64Views:602The Game Reserve of Nagydobrony extends on a marginal area of a former peatland and is covered with extended hardwood gallery forests and oak-hornbeam forests and is surrounded by a mosaic-like agricultural landscape. Due to its richness of nature-like and semi-natural habitats it supports a diverse insect assemblage. By light and bait trapping 383 species of macro-moths were recorded from which larvae of 85 species are feeding either on forest trees and scrubs or on cultivated plants thus these can be considered as potential pest species. Thirteen species (mostly Geometridae and Erebidae: Lymantriinae) have a special significance for forestry due to defoliating activity in gradation periods. Considering the habitat connections, the composition of moth assemblage is dominated by generalist species with broad spectrum of ecological tolerance but the species connected with humid forested habitats are also richly represented. The bulk of species consists of widely distributed Euro-Siberian species, but also some Holo-Mediterranean species with more southern character and Mediterranean-Subtropical migrant species were registered. The bait trapping provided significant results on the phenology of the dominant species. The faunistically significant and/or protected species were observed in a low number of individuals only, thus the applied trapping methods did not damage the faunal composition.
