The Legal Rules Pertaining to Land Protection in Hungary
324-331Views:94Buildings in industry, mining, transportation and for personal and commercial activities cover increasingly more valuable agricultural land. The increase of sub-urbanization and vehicular traffic and the spread of malls and other kinds of investments are causing serious harm for not only to human society, but to a whole national economy as well.
The law on agricultural land (1994:LV) contains legal rules for the preservation, use and classification of agricultural land. These rules define the temporary or permanent use of land for agricultural and non-agricultural purposes; the scale of the land-protection fee and the rules of the process on cases in which land is used for non-agricultural purposes without the consent of the land registry. In the field of land classification, the law prescribes the regulations which are to be followed in order to define the net income of agricultural land in Golden Crowns.
Hungarian land protection rules are unique in the European Union, because only few member-states have similar laws to ours. Community law does not regulate the member states, except in the case of land classification, because this is the basis of the tax paid on the agricultural lands, but even here, there are differences among the states. -
The study of environment-conscious attitudes in the food-industry companies of the Northern-Plain Region
155-163Views:78that the world of business, profit and work is not a hermetically closed area, but is in interaction with its closer and wider surroundings, ultimately with society and the natural environment.
The affectedness of each sector and company varies. To be able to tackle these problems, first and foremost the commitment of companies towards environmentally conscious attitude is necessary, which can form as a result of inner obligation or outer pressure. Thus companies will be concerned to measure and quantify the environmental effects of all activities.
Some of the companies have already given their votes for environment-protection. Both internationally and at home it seems that the responsible leaders of more and more companies build social, human rights and environmental protection considerations in the objects and values of the company apart from profit maximization.
In my thesis I present the data gathered from a questionnaire survey carried out with food-industry companies in the Northern-Plain Region. The aim of the survey was to evaluate the commitment of companies towards environmental protection via solid data. The fact that more than half of the respondents found the positive effects of environmental protection of little importance and that environmental protection was the last among the aims of some companies reflected greatly in the following outcomes. -
Distribution of the American grapevine leafhopper (Scaphoideus titanus ball 1932) in west Romania
127-130Views:203The vector of Grapevine Flavescens Dorée phytoplasma, the American grapevine leafhopper (Scaphoideus titanus) has been in Europe since 1924. In Romania, the first populations were detected in 2009 in the central, eastern and southern part of the country. Later, the leafhopper was found also in West Romania in 2014. In 2015 and 2017, altogether, 14 sampling sites were studied in two vine regions of this area. The Scaphoideus titanus could be detected in 10 of them with relatively small abundances. During the studies, the yellow sticky traps proved more effective methods than sweep netting. To prevent vineyards from disease, we should do everything against the vector from prevention to chemical protection.

Arrival of invasive pests in our direct environment and control opportunities
23-26Views:246The author refers about the nowadays applied practical plant protection activities against pests occuring on trees, shrubs and turfs of public domains. It is overviewed those insects, diseases and weeds which cause damages and touched also upon disturbing the local residents only and tasks to the plant protection engineer expert to manage them. Among the special features of public domains should be mentioned that the rules are difficult to harmonize according to the legal, public health, and horticulture requirements at the same time. The anti-pesticide attitude of EU and the modest range of pesticides which are applicable on public domains make difficulties in optimal management work. The author draws up proposals how to manage the complex plant protection on public domains.

The influence of crop rotation and nutrition regime in winter wheat on the phytomass remains and the deposits of weed seeds remained in the ground
10-13Views:147An important problem refers to soil weeds seed bank with special reference to brown luvic soils and relationship between vegetal remains
(roots + stub) and nutrition regime – crop rotation plant. A great number of seeds can be found in first 20 centimeters of soil (plowing
layer). This fact causes a high weeds density, which has a negative effect on the cultivated plants leading to partial or total crop loss. -
Remembrance to László Huzián (1923-1996)
5-11Views:116László Huzián was a determining personality of the higher education of Hungarian crop protection more precisely that of the agricultural entomology. Training of the scientific and extension specialists of Hungarian agricultural entomology from 1960 till 1983 would have been unimaginable without him. He was the builder of the agricultural entomology school established by Gusztáv Adolf Manninger, the developer of the training’s essential and organisational standard, who sacrificed his life’s work for developing the crop protection. He found, characterized many pests (E.g. Scrobipalpa ocellatella, Lixus scabricollis, Tanymecus palliatus, Mesagroicus obscurus) new for the Hungarian fauna and worked out a control technology against them. It is important to mention his activity in creating the forecasting of the big field crop animal pests mainly that of the sugar beet pests. One top of his educational work was the wonderful manual „Agricultural Entomology” written with Sándor Bognár in 1979. László Szalay-Marzsó said of this book that it was impossible to write a better one. He has been right. The magnificent crop protection library and the unique richness and accuracy of the animal demonstration material (slides, pictures, preparates, showcases, etc.) established at the Gödöllő University of Agriculture can be thanked to his extraordinary systematizing mentality and tireless efforts.

Ecological Conditions of Agricultural Land Use in Transcarpathia
190-194Views:93The unbalanced anthropogenic effects for several decades resulted in significant technogen damages in the ecosystem of Ukraine. Excessive land development, including the use of slopes, effected the disintegration of the natural balance of lands – arable-lands, meadows, forests, and watershed areas – producing quite a negative effect on the landscape’s nature itself. It has to be stressed that according to other indexes, too, agricultural lands show a tendentious deterioration.
Erosion, caused by water and wind, is one of the most influential factors in the degradation of agricultural soils and in the reduction of the productiveness of benefital lands. Nowadays the degree erosion became significant and it directly endangers the existence of the soil which is a principal chain-link of the agricultural cultivation as well as an irreplaceable element of the biosphere.
The social and political changes in Ukraine’s life demand fundamental modernization in the land utilization both in ecological and in economical aspects. However, these aims can be realized only if, during the developments, we base on the up-to-date results of agronomics, and we do further research in the relations of agricultural land use and environmental protection. According to the latest theories, rational and environmental-safe agricultural production relates to the optimum correlation of the natural- and agricultural- ecosystems as well as to the reconstruction of agricultural areas built on the basis of environmental protection. -

Economic questions of precision maize production on chernozem soil
293-296Views:132It is one of the main topical objective to establish the conditions of sustainable farming. The sustainable development in crop production also calls for the harmony of satisfying human needs and providing the protection of environmental and natural resources; therefore, the maximum consideratio of production site endowments, the common implementation of production needs and environmental protection aims, the minimum load on the environment and economicalness. Precision farmin encompasses the farming method which is adjusted to the given production site, the changing technology in a given plot, the integrated crop protection, cutting edge technologies, remote sensing, GIS, geostatistics, the change
of the mechanisation of crop production, and the application of information technology novelties in crop production. Modern technology increases efficiency and reduces costs. The efficiency of crop production increases by reducing losses and the farmer has access to a better decision support information technology system. In addition, we consider it necessary to examine the two currently most important economic issues: “is it worth it?” and “how much does it cost?”. During the analysis of agricultural technologies, we used the precision crop production experiment database of KITE Zrt. and the Institute for Land Utilisation, Regional Development and Technology of the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen.
During our analytical work, we examined three technological alternatives on two soil types (chernozem and meadow). The first technology is the currently used autumn ploughing cultivation. We extended our analyses to the economic evaluation of satellite navigationassisted ploughing and strip till systems which prefer moisture saving. On chernozem soil, of the satellite-based technological alternatives, the autumn ploughing cultivation provided higher income than strip till. In years with average precipitation supply, we recommend the precision autumn ploughing technological alternative on chernozem soils in the future. On meadow soil, the strip till cultivation technology has more favourable economical results than the autumn ploughing. On soils with high plasticity – considering the high time and energy demand of cultivation and the short amoung of time available for cultivation – we recommend to use strip till technologies. -
Susceptibility of maize hybrids to corn smut diseas
39-42Views:189Corn smut disease is one of the most common maize diseases. In the previous years the disease lost from its importance, however nowadays it is becoming more and more important and widespread. The protection against it encounters great difficulties, therefore it is important to emphasize prevention and resistance based protection. The aim of the research was to investigate under laboratory circumstances the resistance of Hungary’s most commonly cultivated maize hybrids to corn smut disease. Twelve species were investigated. We distinguished two susceptibility groups within the hybrids based on the investigated parameters. The results are intended to assist the protection against corn smut disease and to make a suggestion for the farmers so that they could apply more environmental friendly and economical production.

Plant protection praxis on Hévíz Nature Conservation Area (Lake Balaton District, Hungary)
81-83Views:170The nature conservation park, which belongs to the Spa and St. Andrew Hospital for Rheumatics of Hévíz, is 60 ha in size. The famous Lake of Hévíz, the two overfalls and the main buildings of the hospital are located in the middle of the park. They are surrounded by protective forests, parks and gravel esplanades. During the past few decades, the population of neophyton plants and invasive insects have increased considerably. These mean serious challanges to develop efficient control methods. Special care must be taken of environmental and plant protection regulations. Keeping plant protective regulations are especially strict around natural and spa waters.

Susceptibility of stem infected sweet corn hybrids to common smut disease
55-57Views:428The common smut of maize (corn smut, Ustilago maydis /DC/ Corda) can cause large economic losses in susceptible sweet corn hybrids as well. The protection against this pathogen is fundamentally based on prevention. Many methods to control corn smut have been recommended or evaluated, including crop rotation, sanitation, seed treatments, modification of fertility, and biological control. In spite of these frequently mentioned control strategies, the host resistance seems to be the only effective method to manage common smut in those areas where Ustilago maydis is prevalent.

Preliminary estimation of the efficacy of Fusarium sporotrichioides Sherb. as biological control agent against common milkweed (Asclepias syriaca L.)
201-204Views:307A study of fungi responsible for severe leaf spots of common milkweed (Asclepias syriaca L.) in the Hajdúság region (East Hungary), Fusarium sporotrichioides and Alternaria alternata were isolated from infested leaf tissues. F. sporotrichioides was the most virulent fungus in pathogenicity tests conducted on healthy leaves of common milkweed plants. Inoculation of common milkweed (A. syriaca) in different growth stages with F. sporotrichioides yielded similar symptoms as the original ones. Spray mixtures containing 1.0×106 conidia/ml gave effective control when common milkweed plants were sprayed until runoff occurred. Laboratory (wet chamber) and field experiments showed that asexual spores of the fungal pathogen, F. sporotrichioides, exhibited bioherbicidal activity against common milkweed (A. syriaca).
More efficient control efficacy was observable on elder plants (at flowering stage) than younger ones. These results initiate that this fungus may be a biocontrol agent for controlling this invasive weed but should clarify its hosts because it could infect cultivated plants as well.

Review of the biology of plant psyllid (Cacopsylla pruni, Scopoli 1763), and its role in the spreading of European stone fruit yellows, ESFY-phytoplasma with Hungarian data
25-33Views:360The European stone fruit yellows (ESFY) phytoplasma disease caused by pathogen ’Ca. Phytoplasma prunorum’ induces serious damages in cherry, sour cherry, peach, and apricot orchards mostly in Europe. Its known vector is the plum psyllid (Cacopsylla pruni). Many articles report on the biology (morphology, taxonomy, life cycle etc.) and the method of transmission of the pathogen by the vector, and the possibilities of their control. This paper reviews our knowledge about the vector, and summarises the results of an inland research carried out in a northeastern Hungarian apricot orchards. Our goal was to show some important data for the farmers or anyone who is interested in this disease and its vector. And give some known method that we can protect our orchards against them to prevent the appearance of the disease. As the psyllid that became infected with the pathogen can hold its infectionous capacity during their lifetime, it is very important to have enough knowledge about their lifecycle, that we can determine the right time and method to control them. We also have to know how to identify them; therefore, this paper lists several important data which can be helpful. The most important keys of identification are their wing color, which dark borwn in the apex and brown is in the remaining part of the forewing. The length of the antennae is also an important factor, since other genuse’s species have longer antennae than twice the width of the head. C. pruni has as long antennae as twice the width of the head. They return to Prunus species in early spring and we have to protect our orhards in this period against them. We have to use preparations with a knock down effect on them to prevent the inoculation of the pathogen into the trees in our orchards.

Characterization of two rust fungi related to biological control concept in Hungary
195-199Views:312Weeds cause serious problems in agriculture on a global scale. These plants reduce yield and the quality of crops by competing for water, nutrients and sunlight. The improper or excessive usage of herbicides have led to development of resistance in some weed species while contaminating the environment; therefore, biological control has an increasing role as an alternative method for controlling special weed species.
The aim of this study is to make a brief review of biological control of weeds by pathogens and to characterize two rust fungi (Puccinia lagenophorae and Puccinia xanthii) which are broadly examined recently in a biological control concept and have been found on their hosts, such as common groundsel (Senecio vulgaris L.) and common cocklebur (Xanthium strumarium L.), two common and difficult to manage weeds both in horticultural and agricultural lands also in Hungary.

Azoxystrobin resistance of Botrytis cinerea Pers.:Fr. isolates
56-63Views:108Fungicide resistance is one of the most important problems endangering the effectivity of practical plant protection today. The frequent and subsequent usage of specific fungicides results the emergence of resistant fungal populations. This threatens is especially high in case of Botrytis cinerea Pers.:Fr. being an endemic pathogen with frequent infection. Nowadays the main method of protection as against Botrytis cinerea is the application of chemical fungicides chemicals. Therefore, a better knowledge of local populations is necessary for the planning of the protection procedures.
Based on the results of our examinations we may establish that the growth of the examined samples showed a significant difference under in vitro circumstances, which shows a great deal of variability of the Botrytis cinerea populations in Hungary. Twenty-five Botrytis cinerea samples from different hosts were analyzed in this study. High resistance was found towards azoxistrobin in seven cases, and low resistance in eight cases.
It was also proved, that the B. cinerea is able to bypass the inhibition site of the azoxistrobin via the alternative oxidase. The presence of this altermative mitocondrial electrotransport route considerably reduces the effectivity of the chemical. -
Evaluation of Hungarian show-jumping results using different measurement variables
81-85Views:189The aim of the study was to compare different fitted models for show-jumping results of sporthorses and to estimate heritability and repeatability value. Show-jumping competition results collected between 1996 and 2011 were analyzed. The database contained 358 342 starts of 10 199 horses. Identity number, name and gender of the horse, rider, competition year, the level and location of the competition and placing were recorded in the database. To measure performance of horses, placing, number of starters and competition level were used. Competitions were categorized into five groups based on their difficulty level. The used repeatability animal model included fixed effects for age, gender, competition place, year of competition (and competition level in case of non-weighted measurement variables), and random effects for rider, animal and permanent environment effect. Variance components were estimated with VCE-6 software package. The goodness-of-fit of the models was low and moderate. Heritability and repeatability values were low for each measurement variables. The best goodness-of-fit model the weighted square root of placing resulted the highest heritability and repeatability value h2=0.074 and R=0.296.

The Usage of New Multispectral Satellites in Agro-Environmental Protection
282-289Views:134GIS, and especially remote sensing, offers great help in performing agro-environmental protection tasks. It can process a large amount of data to an arranged set of databases, and is also an excellent source of information. Moreover its keeps the geographical coordinates of all data during processing. The usage of remotely-sensed data is one of the most up-to-date and effective ways to observe, analyze and understand the complex phenomena taking place in all the spheres of agricultural production (soil, water, air), and also to track and monitor the changes of different environmental parameters, as they constantly change in time and space. Several indices will be described, which can be derived from remote sensed data. Next, a relatively new hyperspectral satellite sensor (MODIS) will be introduced, as it can be a input data source in research performed in agri-environmental protection. Last, a new meteorological satellite (MSG-1) will be introduced, as its data are available for public usage, and it could be an important data source.

Nutrient deficiency and effects of various nutrition technologies on crop health
109-113Views:295The impacts of climate change on crop production are increasingly noticeable. Extreme weather conditions – such as devastating droughts, which occur more often – have serious effects on crop conditions, thus damaging their defence ability against pathogens and pests. Therefore, in order to achieve high-quality and high yielding crops, it is urgent to elaborate new technologies that improve general condition of crops and prevent development of nutrient diseases. Those crops which suffer from the lack of certain nutrients are more sensitive and their tolerance against diseases are decreased. Nitrogen – as the most influencing macronutrient in yield – is also essential in maintaining crop health. Nevertheless, due to the complicated processes in soil (such as leaching, denitrification), the utilization of nitrogen is not nearly complete, therefore nitrogen stabilizers may be needed to maximize this factor. The use of these stabilizers can be promising where plants with high nitrogen content are grown, although further experiments are needed in which impacts of nitrogen stabilizers on crop protection aspects are examined as well, since there is a close correlation between exaggerated nitrogen fertilizing and sensitivity to pests. During my research I am going to examine the combined effect of foliar fertilizer and nitrogen stabilizer on crop health. Furthermore, my goal is to find clear correlation between pathogens and the different technological variants of nutrition.

Allelopathic effect of invasive plants (Eriochloa villosa, Asclepias syriaca, Fallopia x bohemica, Solidago gigantea) on seed germination
179-182Views:317The aim of this study was to determine the allelopathic potential of invasive species woolly cupgrass (Eriochloa villosa), common milkweed (Asclepias syriaca), bohemian knotweed (Fallopia x bohemica), and giant goldenrod (Solidago gigantea Ait.) on germination crop (Lepidium sativum L.). Experiments were conducted under laboratory conditions to determine effect of water extracts in petri dish bioassay. Water extracts from fresh biomass (leaves and stem) of invasive weeds in concentrations of 4 and 8 g/100 ml were investigated. All invasive plants showed allelopathic effect on germination. In giant goldenrod stem water extract experiment, allelopathic effect was less pronounced.
The cress germination was greatly suppressed with the woolly cupgrass, common milkweed and the giant goldenrod. The experiment showed that the seed germination depended on the concentrations and the plant material used (leaves and stem).

Sunflower in Romanian agriculture
153-163Views:214Romania is one of the largest producers of sunflower closely followed by Bulgaria, Hungary, France and Spain. The total sunflower production increased after 1990, due the increase of cultivated surface during the moderate yield average increasing rate. Last year, Romania was ranked first in the European Union (EU) for the area cultivated with sunflower and the total production of sunflower seeds, according to the National Statistics Institute (INS). Romania's position on the map of sunflower producers area is supported by about 1 million hectares sown. In the segment of sunflower productivity, Romania has an unfavourable position, situated in the last places in the classification of the EU's most productive agricultures. In order to increase production per hectare, it is required to perform measures aimed at the elements of sustainable cultivation technology, including the stability of the production level by ensuring phytosanitary protection.

Special landscape values of the settlements in “Érmelléki löszös hát” geographical micro region
45-50Views:130The objective of this study is to present the concept and significance of special landscape values. The research explains special landscape values within landscape protection using Hungarian scientific literature as well as international and national law. In the last decades the measurement and conservation of non-protected landscapes and landscape elements were emphasised by landscape protection. One of the biggest research of the last years was TÉKA project, done by Corvinus University of Budapest Faculty of Landscape Architecture. The program dealt with surveying Hungarian landscape values. In this paper I am going to analyse the types of special landscape values and their frequencies on a plain region using an open database prepared by TÉKA program. In addition to the definition of special landscape values in the Érmellék loess ridge geographical micro region the study intends to reveal the advantages and disadvantages of using the database.

Usage of Different Spectral Bands in Agricultural Environmental Protection
123-126Views:97Hyper and multispectral imaging systems are widely used in agricultural and environmental protection. Remote sensing techniques are suitable for evaluating environmental protection hazarsd, as well as for agriculture resource exploration. In our research we compared aerial hyper and multispectral images, as well as multispectral digital camera images with the background data from the test site. Hyperspectral records were obtained using a new 80-channeled aerial spectrometer (Digital Airborne Imaging Spectrometer /DAIS 7915/. We have chosen two farms where intensive crop cultivation takes place, as test sites, so soil degradation and spreading of weeds can be intensive as a result of land use and irrigation. We took additional images of air and ground with a TETRACAM ADC wide band multispectral camera, which can sense blue, green and near infrared bands. We had detailed GIS database about the test site. Weed and vegetation map of the area in the spring and the summer was made in 2002. For soil salt content analysis, we gathered detailed data frome an 80x100 m area. When analyzing the images, we evaluated image reliability, and the connection between the bands and the soil type, pH and salt content, and weed mapping. In the case of hyperspectral images, our aim was to choose and analyze the appropriate band combinations. With a TETRACAM ADC camera, we made images at different times, and we calculated canopy, NDVI and SAVI indexes. Using the background data mentioned above, the aim of our study was to develop a spectral library, which can be used to analyze the environmental effects of agricultural land use.

New challenges in soil management
91-92Views:227Soil management represents two important tasks that are harmonization of the soil protection with demands of the crop to be grown on the given land under prevailing farming condition. Further goals are to preserve and/or develop the soil physical, biological and chemical condition and to avoid the unfavourable changes of the soil biological activity and the soil structure. Classical authors emphasised the importance of creating proper seedbed for plants. In the physical approach, tillage was believed to play an important role in controlling soil processes. Consequently, the period of several centuries dominated by this approach is referred to as the era of crop-oriented tillage (Birkás et al., 2017). The overestimation of the importance of crop requirements resulted in damaging the soils, which inevitably led to turn to the soil-focused tillage. Since the first years of climate change, as the new trends have raised concern, tillage must be turned into a climate-focused effort with the aim of reducing climate-induced stresses through improving soil quality.The development of soil management has always been determined by the economical background. At the same time, deteriorating site conditions have contributed to the conception of new tillage trends by forcing producers to find new solutions (e.g. dry farming theory in the past or adaptable tillage theory nowadays). Győrffy (2009) recited the most important keywords were listed in 2001 and that seemed to be important in the future of crop production. These keywords (endeavours) were as follows:− Biofarming, organic farming, alternative farming, biodynamic farming, low input sustainable agriculture;− Mid-tech farming, sustainable agriculture, soil conservation farming, no till farming, environmentally sound, environmentally friendly, diversity farming;− Crop production system, integrated pest management, integrated farming, high-tech farming;− Site specific production, site-specific technology, spatial variable technology, satellite farming;− Precision farming.Győrffy’s prognosis proved to be realistic and the efforts mentioned above have mostly been implemented. New challenges have also appeared in soil management in relation to the last decades. The most important endeavours for the future are:1) Preserving climate-induced stresses endangering soils.2) Turn to use climate mitigation soil tillage and crop production systems.3) Applying soil management methods are adaptable to the different soil moisture content (over dried or wet may be quite common).4) Use effectual water conservation tillage.5) Use soil condition specific tillage depth and method.6) Adapting the water and soil conservation methods in irrigation.7) Preserving and improving soil organic matter content by tillage and crop production systems.8) Considering that stubble residues are matter for soil protection, humus source and earthworm’ feed.9) Site-specific adoption of green manure and cover crops.10) Applying site-adopted (precision) fertilization and crop protection. Considering the development in agriculture, new endeavours will occur before long.
