Portable snapshot spectral imaging for agriculture
221-225Views:275High-resolution proximal and remote sensing applications can consolidate sustainable, prevention- and precision-oriented crop management strategies to decrease production risks. This paper shows significant perspectives, own developments and technical aspects of high resolution remote sensing in the context of field applications. Moreover, we provide an overview of snapshot hyperspectral imaging and potential field video sensors to identify areas of interest for their future development. One of the main conclusions of our paper is that non-scanning snapshot hyperspectral imaging technology may enable researchers to overcome the gap in the “point to image” transition of field sensing, while providing a flexible solution for regular variable-rate applications.

Study on Human Resource Management in Agriculture
171-181Views:93The human factor has been reassessed with regard to strategic initiatives towards obtaining and preserving competitive advantage. Knowledge, experience and special skills are a specific form of capital, forming part of the organisations’ assets and serving as an organisational strategic resource. Their development and use require major investments, both on the part of the individual and the organisation. In a Europe undergoing integration, the quality of human resources enjoy priority among our really important values and specific features. The opportunities of the near future can be utilised, and agricultural economic organizations can survive and increase their organizational effectiveness, if they possess a basis of human capital which is able to make a shift in perspective and behaviour which is of primary importance from the point of view of incorporating market mechanisms and implementing them in practice. My investigations were focused on the current position of human resource management in a comprehensive manner; further, on the approach of top managers regarding the future. Analysing the business and other indicators of the companies studied, I have set the objective to describe the differences and special features of the human resource management practice of companies, which are different in size, operational form, and from the perspective of success or failure.
Human resource management is directed to attracting, retaining, motivating and utilising labour. A given work process can be successful or unsuccessful – given the same conditions – depending on who performs it. Therefore, human resource management related tasks require special attention when enterprises are planned, established and operated. On analysing the responsibilities of human resource management, I have found that the functions and responsibilities of human resource have low or medium importance in the operation of economic organisations today. Regarding the future, top managers have expressed higher expectations of human resource management responsibilities in all areas and they consider individual functions to be more important. The establishment and operation of a human resource information system has been presented as the most important need for change. Correlation analyses have proved that the higher the sales revenues of a company, the higher the development of human resources is regarded by its manager, and the same holds for training, career support and a proper establishment and continuous evaluation of job profiles. -
Morphological diversity of current melons (Cucumis melo) compared to a medieval type
84-90Views:159Morphological diversity of melon (Cucumis melo); phenotype reconstruction of a medieval sample. Morphological diversity among 47 melon (Cucumis melo) cultivars and landraces from Hungarian germplasm collection (ABI, Tápiószele) were analyzed with an ultimate aim to characterize morphologically cv. Hógolyó, which showed the closest genetic similarity to a medieval melon recovered from the 15th century. Cultivars based on fruit morphology were grouped into the three main types of melon as reticulatus, cantalupensis and inodorus. Cluster analysis (by SPSS-11) based on 23 morphological (quantitative and qualitative) traits recorded revealed an extreme diversity among accessions, nevertheless cultivars were clustered into main melon clusters with only two exceptions of inodorus type cv. Zimovka J. and Afghanistan. Cultivars Sweet ananas and Ezüst ananász; and two Hungarian landraces Kisteleki and Nagycserkeszi showed close similarity. Cultivars Hógolyó and Túrkeve of inodorus type
were also grouped in one cluster, which provide insight into the morphological reconstruction of the medieval melon recovered from the 15th century. These results also indicate that old Hungarian landraces could be re-introduced into breeding programs for broadening genetic base of melon. -
Employment trends in the Northern Great Plain’s Region
109-111Views:113Hungary can be divided into 7 regions, of which I am writing about the Northern Great Plain Region in this article. The Northern Great Plain consists of the counties Hajdú-Bihar, Jász-Nagykun-Szolnok, and Szabolcs-Szatmár-Bereg. There are 389 settlements in the region, which can be considered rather few. The population of the region is nearly 1.5 million, which is nearly 15% of the total population. This region is one of the most disadvantageous regions in Hungary, with its economic indicators ranking the lowest of all regions. Nevertheless, as regarding education and agriculture, the region is considered to be a prominent area.

The role of disease resistance in the registration of crop varieties in Hungary
27-29Views:143Variety testing including disease resistance test of the major crops has been carrying out since the 1960’s in Hungary. Testing for resistance of the new candidate varieties is performed in the so-called VCU (Value for Cultivation and Use) trials under natural infection and in special small-plot or micro-plot trials using different disease provocative methods. Disease resistance, especially those of multiple and horizontal-type (race non-specific, partial or durable) resistances, has recently become a key limiting factor in the state variety registration. The role of disease resistance in the decision-making process of variety registration is demonstrated on the examples of winter wheat and sunflower as two major field crops in Hungary.

The effect of various composts on vegetable green mass on two soil types
179-183Views:180Composting of sewage sludges makes easier the utilization of sewage sludge in the agriculture and the composts in good quality could increase the nutrient content of soil. Due to the composting process, the sewage sludge composts with high organic matter content can be utilized in the same way as other composts or farmyard manure.
Composts produced in different ways have different effects on the physical, chemical and biological properties of different soils, although their positive effects have already proved in the literature. In our study the effects of composts from different composting processes were investigated in soil-plant systems. The different physical and chemical properties of the two examined soil types (arenosol and chernozem)strongly influenced the nutrient supply capacity of composts which could be characterized by the growth of ray-grass as a test plant in the pot experiment. In this work we examined the effects of three different composts on the green weight of plants on the fourth and eighth weeks after the treatment and sowing. -
Regional differences of the agricultural and rural development sector
343-347Views:104Is neccessary and possible to take in consideration the regional differences of agriculture- and rural development in the rural development program for period 2014–2020? For answer of this question we try to give some references by reveal of economic and social regional differences.

Effects of cultivation methods on some soil biological parameters of a meadow chernozem soil (Vertisols)
61-66Views:85The effect of extended drought conditions on soil, the unfavourable cultivation technologies and the application of chemicals have been enhancing the processes of physical and biological soil degradation, so the fertility of soil is gradually declining.
The effects of two cultivation methods – traditional ploughing (TP) and conservation tillage (CT) – on the biological activity of a meadow
chernozem soil were examined in a long term experiment. Different parameters of the biological activity of soil were determined. These are
the numbers of total bacteria, microscopic fungi, aerobic cellulose decomposing bacteria, as well as the activities of some important soil
enzymes and CO2 production.
Conservation tillage seemed to be a more favourable cultivation method for the majority of microorganisms, the activities of urease and
dehydrogenase enzymes and CO2 production, compared to the traditional ploughing system. These parameters increased significantly,
especially in the upper layer of conservation tillage plots. Concerning the plant cultures, the majority of microbiological parameters were
higher in the soil of vetch (Vicia sativa L.) depending on the cultivation methods, so involving the pulses to the crop-rotation seems to be
very important in this soil type.
According to the ninth year’s results, the importance of conservation tillage as a means of protecting the soil biological activity in meadow
chernozem (Vertisols) can be established; it was proven by microbiological investigations. -
Challenges and limtations of site specific crop production applications of wheat and maize
101-104Views:149The development and implementation of precision agriculture or site-specific farming has been made possible by combining the Global Positioning System (GPS) and the Geographic Information Systems (GIS). Site specific agronomic applications are of high importance concerning the efficiency of management in crop production as well as the protection and maintenance of environment and nature. Precision crop production management techniques were applied at four locations to evaluate their impact on small plot units sown by wheat (Triticum aestivum L.) and maize (Zea mays L.) in a Hungarian national case study. The results obtained suggest the applicability of the site specific management techniques, however the crops studied responded in a different way concerning the impact of applications. Maize had a stronger response regarding grain yield and weed canopy. Wheat was responding better than maize concerning plant density and protein content performance.

Examinations of the carbon dioxide emission of the soil in the case of different tillage methods in a field experiment
209-212Views:243Today's global challenge is the increasing concentration of carbon dioxide (CO2) and other greenhouse gases in the air. The level of CO2 emissions may be significantly affected by the agriculture and, more specifically, the applied tillage method, even though to a lesser extent than industrial production. On a global scale, the CO2 emission of an agricultural area is insignificant in comparison to that of a large-scale plant in an area of the same size, but areas under cultivation, including arable land, have a large global area. In this paper, we investigated the relationship between applied soil tillage methods and carbon dioxide emissions in the case of different fertiliser treatments. In our experiment we examined four types of tillage with five different fertiliser effects. Comparing fertiliser treatments and tillage methods, it was found that their interaction significantly affected carbon dioxide emissions, the lowest value was obtained in the case of the 210 l ha-1 Nitrosol+N-LOCK – tillage radish treatment. Strip and tillage radish methods have relatively homogeneous, low value. -
The Natural, Social and Economic Conditions and Opportunities for Development of Balmazujvaros, Especially in the Case of the Co-operative Kvaliko
77-85Views:98Balmazujvaros as a settlement near Hortobagy has to cope with both advantages and disadvantages. Its natural and social conditions are mainly given, the agricultural characteristic is dominant, and the number of the employed is the highest in the agricultural firms and processing industry. Developing the third sector, including hosting, tourism, eco-tourism, thermal-tourism, may be an opportunity for the city. The subsidy for rural development relating to the SAPARD-programme may contribute to this, as the city is the member of the Association of Hajdu Towns.
The agriculture plays an important part in Balmazujvaros in which production and marketing of vegetables and fruits excel. Several farmers realised this opportunity and founded the Marketing Co-operative of Vegetable Producers in Eastern Hungary, that is the Kvaliko. This PO works in a Corporation form and is constantly developing, spreading and expanding its choice making use of the local natural, social and economic conditions and applications for realising its investments. This PO may set an example for the other entrepreneurs and farmers of Balmazujvaros to co-operate and it may be considered as an already realised opportunity. -
Stand evaluation, crop estimation and yield analysis of winter wheat for the optimization of yields
103-109Views:135The authors have been carrying out stand evaluation, crop estimation and yield analysis in winter wheat since 2012. The sampling areas were assigned at the fields of the Training Farm of the Faculty of Agricultural and Food Sciences of Széchenyi István University Mosonmagyaróvár according to the structure of the cropping system. According to their observations the value of field emergence is always lower than the laboratory germination. The weak emergence is important because the lower plant density cannot be compensated by the increased tillering in spite of having larger plant growth space. It is proven by the fact that they detected strong productive tillering even at 5 and 10 mm plant spacing while there were single-spiked plants at 40-50 mm plant spacing as well. The analysis revealed that the total ear mass and grain mass of wheat plants bearing two or more ears is almost the double than that of the single-spiked plants. It was a further basic experience that the largest ear of ”multiple-spiked” plants is always heavier than the single ear of one-spiked plants. Plants with intense tillering and more ears demonstrate the importance of proper seedbed preparation and drilling and the significance of sowing good quality seeds. These are the factors that determine field germination and emergence, influence the speed and intensity of initial development and by all these factors the sufficient productive tillering. The authors emphasize the use of exact and objective methods at crop estimation, e.g. the relationship between the ear mass and the yield which is in strong correlation whilst ear length and grain mass are not suitable for a precise estimation. The authors conclude that crop estimation and yield analysis must be inevitable tools of modern crop production and will be particularly important in precision agriculture. These tools also qualify the job done by farmers and helps to identify the areas that require special attention.

Effect of Silver willow “Russian olive” (Elaeagnus angustifolia) on extensive sheep management
157-162Views:105We carried out a study in the Karcag Research Institute, which affected the areas of narrow-leaved silver willow. In the framework of this research, we performed Balázs's coenology, and thus established the degree of Borhidi degradation, which resulted in the fact that the areas of the silver willow were degraded practically irreversibly, the diversity of the grassland has decreased. We consider it very important to study these grassland areas of silver willows, as they can provide an additional fodder base for sheep grazing, which will also increase the sustainability of the grassland. The obtained soil analysis results show that the soil samples of the silver willow areas are richer in nitrogen (p-value: 0.006) and phosphorus (p-value: 0.003) than the examined control area.

Connections of the Economic, Ecological-Environmental and Social Functions of Rural Development in Communities Bordering the Hortobágy
203-211Views:93investigated the economic, ecological-environmental and social functions of rural development in communities bordering the Hortobágy National Park, such as in Balmazújváros, Hortobágy, Tiszacsege and Egyek. My purposes focused on four issues: (1) to work out a method on the basis of the examined and cited literatures, which defines the development of communities from economic, ecological and social aspects of rural development; (2) to reflect the changes in the role of agriculture; (3) to analyse the effects, advantages and disadvantages of Hortobágy National Park in relation to the economic, ecological and social lives of the examined communities; and (4) to make an economic analysis on the alternative income sources of Hortobágy, such as rural tourism, herb production and bio-farming in a family farm structure. When measuring the development of the communities I concluded that complex indexes hide the real consideration of the three functions of rural development and the possibility for comparing them on a community level. Furthermore, these 19 indicators are not enough to evaluate the situation, thus I raised the number of indicators and handled them on the basis of the three functions of rural areas. I classified the economic, ecological and social indicators into indicator groups within each functions, which make the determination of causes for underdevelopment possible. While only Tiszacsege and Egyek were considered to be backward on the basis of the complex index of the Hungarian Central Statistical Office, my investigations showed that even Balmazújváros and Hortobágy proved to be lagged behind from both economic and social aspects. The methodical development justified the hypothesis that few indicators are not enough to establish decisions objectively. New developmental orders emerged. Measuring development of communities may be all-rounded and more established by using this new method, which may result in objective preparation of decisions in rural development and more rational spreading of subsidies.

Usage of different remote sensing data in land use and vegetation monitoring
7-12Views:153The use of remote sensing in forest management and agriculture is becoming more prominent. The rapid development of technology allowed the emergence of database suitable for precision application in addition to the previously used low-resolution and low data content images. The high resolution, hyperspectral images are not only suitable for separating the different land use categories and vegetation types but also for examining the soil characteristics and biophysical features of plants (Blackburn and Steel, 1999; Condit, 1970). We processed a multispectral satellite image (Landsat 7 ETM+) and a hypespectral areal image (DAIS 7915) about a farm on the plains and evaluated the different image classification methods. During our examinations, we examined the geometrical and radiometrical characteristics of images first, then assigning the training areas, we determined the spectral characteristics of land use categories. We performed a multispectral analysis for checking land use, where we compared controlled and uncontrolled classification systems to check their reliability. We used areal and spectral reductions to make the classifications more accurate and to reduce the length of calculations.

The Connection of Capital Leverage and Profitability by the Corporate Agriculture Enterprises
35-39Views:99The analysis of capital system of agricultural corporations is a key issue of economics and the effect of it's fluctuation can be observed on several fields of the life of corporations.It influences
for example the assets-, financial- and income situation of the enterprises.The aim of this study is to analyse the connection between capital structure and profitability in order to reveal such
a ratio for the capital leverage and liabilities, by which it can say, to that connect the profit or loss. By the analyse get activity- and size specified results.With the empyrical results I determine the quantile point between the profitable or the non profitable operating. -
Regional economic achievements and reindustrialisation in Hajdú-Bihar county
65-74Views:215The North Great Plain region is one of the backward regions of Hungary. The low level of economic development is mainly due to the lack of industrial development. The region is poor in natural resources, its main resources are land, natural gas fields, carbon dioxide, thermal water and the clay mineral stock.
The structure of GDP per capita of the county is different than the country average mainly because of the high proportion of agriculture.
The proportion of the industry and the building industry is not significant. Of the various service provider sectors, trade, transport and telecommunications have a small proportion, while financial and economic service providers have even lower share, which is due to the fact that these sectors are mostly concentrated in Budapest. The share of public and human service prodivers is higher than average due to the University of Debrecen.
The GDP which expresses the economic development of the county in a complex way increased four times its previous value in nominal value between 1995–2009. However, if the real value is considered, the increase is less than 25%, as opposed to the country average, which was less than 40%.
The most complex index of the development level of an economy is GDP expressed either in nominal or real value. If expressed in dollars, GDP is suitable for international comparison with the correction based on the purchasing power parity per person.
The county represents 4.3% of the people employed in the industrial sector in Hungary, while its share in industrial production is only 3.3% which is lower than the regional and population share of the county within Hungary. As regards industrial production per person, Hajdú-Bihar was the 10th county in Hungary; therefore, it is considered to be a less industrialised county.
The product structure of GDP is suitable for drawing useful development conclusions, but the result is more reliable if the income creation ability is also analysed on the basis of the employment structure. -
Milestones in the development of agronomic management practices in crop production
203-209Views:159From the dawn of the history of the human race, agriculture has always been a profound activity of mankind producing food and feed as well as various plant originated materials for further processing.
Agronomy, like any other human activity, depends on the perpetual development of knowledge and technical skills, - in a modern context – science and innovation. This paper is intended to provide the reader with information regarding the main phases of the development of agricultural production from the Neolithic societies through the early Mesopotamian and Egyptian empires to the inventions of first organised learned society of Rome. The major research findings of the past two millennia including agro-chemistry, genetics and technical development are presented.
Such a review should not lead to any scientific conclusions, but rather a philosophical postulate similar to that of Jonathan Swift written some centuries ago: “And he gave it for his opinion, that whoever could make two ears of corn, or two blades of grass, to grow upon a spot of ground, where only one grew before, would deserve better of mankind, and do more essential service to his country, than the whole race of politicians put together”.

Economics of site specific crop density in precision sunflower (Helianthus annuus L.) production
91-96Views:165In this research, the crop density of sunflower was examined, which, thanks to the tools available for precision crop production and knowledge of the market environment of sunflower production, best fits the heterogeneous areas of the given production zones and meets the economic requirements. These components together directly influence the effectiveness of sunflower production. In the year of 2021 and 2022, we carried out a site-specific crop density sunflower experiment in two fields with the same soil type, by sowing significantly different amounts of seeds within the given zones. We have established that the sunflower, although a plant with excellent adaptability, reacts sensitively to the place of production and the effect of the year, in zones with heterogeneous productivity, and shows a reaction to sowing with a variable number of seeds per zone, even when examined based on economic aspects.

Examination of Reproductive Performance of Roe Deer (Capreolus capreolus) in Hungary
33-38Views:138The objective of the research partly is to compare the reproduction performance of the populations living in different regions with regard to some special characteristics (age, condition).
When estimating the age through tooth wear and cementum-layer-counting there was a difference of 0.87 years in favour of the first one (r=0,840; p<0,001). I found cementum layers at 42% of the does in the study after examining the MI teeth.
There was lose connection between the weight (eviscerated, with head and legs) and the KFI (r=0,296; p<0,01), and for further analysis, I used only the KFI as the index for condition.
The regional average KFI varied from 0.24-0.37 in fawns, 0.82-1.73 in does, with individual extremes of 0-4.05. Within the examined regions the highest index belonged to the prime-aged does, while the 1-year-olds had a lower rate, and it was the lowest in the does older than 8 years.
The rate of fertility was between 83,3(ns)-100% as we can see from the presence of the CL. All the examined does were fertile, except in one region, while among the female fawns in two regions I only found three with active ovaries. The average number of CL was 1.5-2.13, and this varied by regions; all in all it was the highest in the 2-7-year-old group (1.96) and in the ones over 8 years (2.00!), while it was lower in the does younger than 1 year (1.90). The high fertility of the does over 8 years is remarkable.
I could examine the number of embryos in two regions during the post-implantation period, and beside 100% fertility I found significant differences among the does, which can be associated with the condition. The ratio of CL carriers and the pregnant does was 100% and 73% in the two regions, the average number of CL were 1.92 and 1.72, while the average embryo number were 1.83 and 1.36 per doe. The difference between the CL and the embryo numbers on the two regions were 5% and 21%. The difference (prenatal loss) is in connection with the age (age class) of the doe. It is possible, however, that in some cases oestrus was not followed by gestation. But in roe deer, owing to the commonly known lack of luteolysis-mechanism (Flint et al., 1994), the regression of the CL of the does that did not get pregnant takes place in December and January, so the CL found in January cannot prove a previous pregnancy, which might have been followed by an abortion.
Although it has to be proven, it seems that the number of the CL (potential progeny) can be associated with the age (r=0,418; p<0,01) and the weight (r=0,312; p<0,01) of the doe, while the embryo number (realised progeny) is influenced by the age of the doe and probably by external factors.
It is essential to continue and extend the research to increase the reliability of the results and their correlation. -
Sequence stability at SSR, ISSR and mtDNA loci of common millet (Panicum miliaceum) from the middle ages
10-19Views:108Seed remains of medieval millet, recovered from a 15th century layer (King’s Palace, Budapest, Hungary), showed reddish yellow grain color after rehydrating on tissue culture medium that was close to grain color of modern cultivar Omszkoje. aDNA of medieval c. millet was extracted successfully, analyzed and compared to modern common millets by ISSR, SSR, CAPS and mtDNA. Analyses of fragments and sequences revealed
polymorphism at seven ISSR loci (22 alleles) and at the 5S-18S rDNA locus of mtDNA. CAPS analysis of the 5S-18S rDNA fragment revealed no SNPs in the restriction sites of six endonucleases TaqI, BsuRI, HinfI, MboI, AluI and RsaI. Sequence alignments of the restriction fragments RsaI also revealed
consensus sequence in the medieval sample compared to a modern variety. Morphological characterization of twenty common millet (Panicum miliaceum L., 2n=4×=36) cultivars and landraces revealed four distinct clusters which were apparently consistent with the grain colors of black, black and brown, red, yellow, and white. In the comparative AFLP, SSR and mtDNA analysis modern millet cv. ‘Topáz’ was used. AFLP analysis revealed that extensive DNA degradation had occurred in the 4th CENT. ancient millet resulting in only 2 (1.2%) AFLP fragments (98.8% degradation),
compared to the 15th CENT. medieval millet with 158 (40%) fragments (60% degradation) and modern millet cv. ‘Topáz’ with 264 fragments (100%). Eight AFLP fragments were sequenced after reamplification and cloning. Microsatellite (SSR) analysis at the nuclear gln4, sh1, rps28 and rps15 loci of the medieval DNA revealed one SNP (single nucleotide polymorphism) at the 29th position (A to G) of rps28 locus compared to modern millet.
Mitochondrial (mtDNA) fragment (MboI) amplified at the 5S-18S-rDNA locus in the medieval millet showed no molecular changes compared to modern millet. The results underline the significance of survived aDNA extraction and analysis of excavated seeds for comparative analysis and molecular reconstruction of ancient and extinct plant genotypes. An attempted phenotype reconstruction indicated that medieval common millet showed the closest morphological similarity to modern millet cultivar Omszkoje. -
Development of precision apple production technologies in Institute of Water and Environmental Management
97-101Views:251From the precision agriculture point of view, by the rapid development of the investigated technological elements – global positioning system (GPS), remote sensing (RS), global information system (GIS) – the number of services, which were not available in the past, because of their speed, complexity or price are increasing. The high accuracy high-tech instruments provide opportunity to elaborate several fruit production technologies, which aim is creating and operating water and energy safe quality fruit production systems. To evaluate these possibilities, experience was carried out in the Study and Regional Research Farm of the University of Debrecen near Pallag with the use of a GreenSeeker 505 Hand Held™ Optical Sensor Unit, and its interface the Trimble AgGPS FmX Integrated Display board computer, and a ScanStation C10 laser scanner by Leica. The results show the absolute applicability of these equipments in precision horticulture.

Effects of water deficit on the growth and yield formation of maize (Zea mays L.)
143-148Views:172Maize (Zea mays L.) is the most important consuming cereal crop in the world after rice and wheat. This requires an understanding of various management practices as well as conditions that affect maize crop performance. Water deficit stress during crop production is one of the most serious threats to crop production in most parts of the world and drought stress or water deficit is an inevitable and recurring feature of global agriculture and it is against this background that field study of crops response to water deficit is very important to crop producer and researchers to maximize yield and improve crop production in this era of unpredicted climatic changes the world over.
A pot experiment was carried out to determine the effects of water deficit on growth and yield formation of maize. Two maize cultivars were used Xundan20 and Zhongdan5485. Three levels of soil water content were used in two stages of water control levels at two stages of the maize plant development
1. The JOINTING STAGE: A. CONTROL (CK) soil water content: from 70% to 80% of soil water holding capacity at the field, soil water content: from 55% to 65% of soil water holding capacity at the field, soil water content: from 40% to 50% of the Soil water holding capacity at the field.
2. The BIG FLARE PERIOD: A. CONTROL (CK) soil water content: from 75% to 85% of soil water holding capacity at the field, soil water content: from 58% to 68% of soil water holding capacity at the field, soil water content: from 45% to 55% of the soil water holding capacity at the field.
This research mainly studied the effects of water deficit on physiological, morphology and the agronomical characteristics of the maize plant at the different water stress levels.
The importance of these results in this experiment will enable plant producers to focus and have a fair idea as to which stage of the maize plant’s development that much attention must be given to in terms of water supply. -
Baking quality of winter wheat (Triticum aestivum L.) in the long-term experiments on chernozem soil
152-156Views:100Agriculture has traditionally an important role in Hungarian economy and rural development. About 75 % of Hungary’s total territory
is under agricultural land use. Because of ecological conditions and production traditions cereals (wheat, maize etc) have the greatest
importance in Hungarian crop production. In the 1980’s the country-average yields of wheat were about 5,0-5,5 t ha-1 („industrial-like”
crop production-model). In the 1990’s the yields of wheat dropped to 4,0 t ha-1 because of low input-using and wide application of the issues
of environmental protection and sustainability. Winter wheat production for quality has a decisive role in certain regions of Hungary
(eastern and middle-parts).
The quality of wheat is complex and different. Three major growing factor groups determine the quality of winter wheat: genotype,
agroecological conditions and agrotechnical factors. In wheat production for quality the selection of the variety is the most important
element. Our long-term experiments proved that the quality traits of a variety means the highest (maximum) limit of quality which could not
be exceeded in fact. During the vegetation period of wheat the different ecological and agrotechnical factors could help or on the contrary
could demage the quality parameters of wheat.
The agrotechnical factors determining the baking quality of wheat can be divided into two groups: the first group means the factors with
direct effects on quality (fertilization, irrigation, harvest); the second group contains the elements with indirect effects on quality (crop
rotation, tillage, planting, crop protection).
Appropriate fertilization could help to manifest the maximum of quality parameters of a wheat genotype and could reduce the qualityfluctuation
in unfavourable ecological and agrotechnical conditions. -
Development of an Agricultural Soil Information System
60-63Views:81Since the development of remote sensing nearly 60 years ago, there have been many applications for agriculture. Some have proved effective, while others have not succeeded in assisting farmers with problem solving. Recent advances in the spatial, spectral and temporal resolution of remote sensing as well as potential positive changes in cost and availability of remotely sensed data may make it a profitable tool for more farmers. The target area of my research program is the fields cultivated by Kasz-Coop Ltd. considering that this firm is one of the main agricultural firms in the region and its cultivated fields are quite heterogeneous.
