The Role of the Digital Terrain Models in the Assessment of Surplus Water Risk at the Szolnok-Túri Plain
47-51Views:122The environmental factors to which surplus water can be assigned (topography, soil, groundwater, vegetation etc.) can be subject to special analysis and the randomness of the occurrences can be limited. The results of these procedures are surplus water risk maps of the areas, which can be utilised in land use planning. The risk map of the research site was created with overlaying digital category maps of the determining factors (hydraulic conductivity, convexity, critical probability of ground water level and land use).

Virtual Appliances for geospatial data management and processing in the Integrated Land Management System (ILMS)
59-62Views:108Virtualization is increasingly taking on a key role in various system architectures which follow new platform concepts like Software as a Service (SaaS). This trend addresses more instant and short-term environments and comes with new methods and strategies for the distribution of mainly complex application stacks not only in large IT infrastructures. The paper presents how a so called Virtual Appliance can be set up in order to operate in virtual server environments using hypervisor software like Oracle Virtual-Box. Using the example of two server-side components within the Integrated Land Management System (ILMS), it will be shown that the use of state-of-the-art methods, standardized tools and interfaces on servers enables different aspects of environmental system management, analysis and planning.

Characterisation of basic water balance parameters of Debrecen
35-40Views:217This work aims to develop a hydrological modelling tool to help managers make the right decisions for Debrecen, in the face of water scarcity and the increase in agricultural and domestic needs over time. The methodology was based on the creation of a climatic database, at monthly time steps, from 2016 to 2019, and cartographic (land use, digital elevation model, and hydrological network). As a next step, the watershed was delimitated into sub-basins to determine the shape and the physiographic characteristics of sub-watersheds. Finally, a hydrological study was prepared by calculating the time of concentration to build a database of water resources in the study area. This water resource will be used as an input parameter for urban farming.

Effects of different crop years and sowing date on maize yield
93-96Views:138We carried out the tests in the flood meadow soil formed on the alluvial cone of Nagykereki, Sebes-Körös belonging to the Bihar plane small region. The aim of the study was to analyse the effect of the different sowing date of maize on the yield trend based on a comprehensive study conducted for 6 years (2007–2012).
The sowing date of maize hybrids is a factor that significantly influences yield, however, its effect is not significant in each crop year. In the years when the date of sowing has a modifying effect, the reliable yield level can be reached with optimal sowing date management (24 April).
The advantage of early sowing (10 April) proved to be dominant in the year of 2012, the seeds were placed into the still wet soil therefore shooting was more balanced. Maize seeds sown at the time of optimal (24 April) and late (10 May) sowing dates were placed into the already dry soil, which deteriorated germination and the strength of early initial development that had an effect on the yield.

Effects of Tillage Systems on Physical Status and Organic Matter Turnover of the Soil
42-45Views:206The cultivation technology for those plant, that play a key role in arable land production need to be renewed in order to reduce production costs and to protect arable land. The modernisation of technologies can only be achieved by applying appropriate tillage systems. Our measurements were carried out on chernozem soil with lime deposits at the Látókép Experimental Station of the Center for Agricultural Sciences, Debrecen University, in long term tillage experiments set up in 1989. We examined the typical physical parameters, the albedo, field capacity, the bulk density of the soil, organic carbon content (humus %) and the measured pH-values in the water solution within the two tillage variations. We have also modelled nitrogen cycle formation in different treatments.
A significant difference occured between the albedos of the two soils, which may be the result of significant amounts of stem remaining on the surface in the case of the reduced tillage method. The yellow, waxy stem of maize reflects 21% of the sun’s rays, especially at the beginning of the vegetation period, when its decomposition has only just started. This delys the warming up in early spring, which delays the sowing time of maize and reduces evaporation. In the two tillage variations, the water management characteristics do not differ practically, the wilting point field capacity are in accordance. In reduced tillage methods, the so-called „plough-pan” can be well measured at 15-20 cm, while in winter ploughing it is at 30 cm. The humus % of the soil does not differ in the two tillage variations, but due to the difference in bulk density this means a different humus and organic nitrogen content. The organic nitrogen content is greater in the reduced tillage method. On the basis of pH value evaluations, we could not detect significant differences in the two tillage variations. The organic nitrogen content of areas where reduced tillage method was applied is higher than in areas where conventional winter ploughing was applied. -
Landscape use of protected areas in the Hódmezővásárhely micro-region
179-193Views:104One of the biggest questions of developing rural areas is that people and organisations living and making their activity there how and in what measure utilize the local or obtainable external
resources. The concept of the landscape expresses the direct connection of the natural resources with the socio-economic processes. This is a two-way connection, (1) on the one hand the single landscapes provide the unique combination of natural conditions for the socio-economic utilisation which is different from other landscapes, (2) on the other hand as the result of the interaction of natural spheres together with the social and economic spheres the landscapes change in a different manner and in a different measure. The landscape as a territorial unit and as a resource is inseparable from the natural resources, and the nature
conservation plays an increasingly important role in the use of the landscape and landscape management, which is an essential task not only in protected areas, but everywhere. The natural resources, the landscape, the nature conservation and the landscape use are related tightly, in which the so-called ecological/biological resources and their sustainable use have a
significant role. -
Drought cycle tracking in Hungary using Standardized Precipitation Index (SPI)
97-101Views:322Drought is one of the natural hazard risks which badly affects both agricultural and socio-economic sectors. Hungary, which is located in Eastern Europe has been suffering from different drought cycles; therefore, the aim of this study is to analyse the rainfall data obtained from ten metrological stations (Békéscsaba, Budapest, Debrecen, Győr, Kékestető, Miskolc, Pápa, Pécs, Szeged, Siófok, Szolnok) between 1985 and 2016, by using the Standardized Precipitation Index (SPI).
The results showed that 2011 was recorded as the worst drought cycle of the studied period, where the SPI ranged between -0.22 (extreme drought) in Siófok, and 0.15 (no drought) in Miskolc. In a similar vein, the study highlighted the year 2010 to be the best hydrological year, when the SPI reached 0.73 (mildly wet) on average. Interestingly, the Mann-Kendall trend test for the drought cycle showed no positive trends in the study area. Finally, more investigation should be conducted into the climate change spatial drought cycle in Europe.

Analysis of Economic Efficiency of Energy Wood Plantations
53-60Views:87After the EU-accession we should have a definite idea about what kind of production structure and land use should Hungary obtain to meet the conditions undertaken in the different governmental decisions. In the course of Hungarian land use, significant changes have taken place in the last eighty years. Further changes are influenced by the fact that according to various decisions, legislative provisions and ideas in a short time the energy orchards’ domiciliation could start in large. For this, financial support can be required from EU-sources. As for the woody energy plants, subsidies can be required for the domiciliation and as for herbaceous plants grants can be required for growing. As far as the latter is concerned, the subsidy will be around 26-27 thousand Ft/hectares according to the plans. However, the cultivation method does not have to be changed to
switch from plow-land to energy plants. The question is if the produced commodity will be received by power plants and if it ensures appropriate income for the farmer. In my research I wanted to find from the given woody energy plants which are those that are the most profitable. -
Agricultural land use and food safety
55-60Views:194The world’s food production needs to be doubled in order to cover the need of the population by 2050 even if it exceeds 9 billion. The output of agriculture is expected to increase by 1.7% every year until 2020 (OECD, FAO 2011) which is a major decrease in comparison with the average 2.6% increase of the previous decade. At the same time, the meat, dairy, sugar and vegetable oil consumption is likely to increase by 2020 to a higher extent than so far. Due to the increasing food prices, the amount of starving people will increase and food consumption will decrease – especially in developing countries – as people will be able to buy less and only cheaper food products. Also, obesity may become a more severe problem and the inequality of the population’s health status could increase.
One of the most important elements of adapting to global climate change is food safety; therefore, it is especially important to breed new biological bases and to introduce production systems which contribute to adapting to changed circumstances.

Life in two countries but one home land – Béla Lipthay (1892-1974) the entomologist
12-23Views:147Béla Lipthay lepidopterologist, entomologist, museologist, agriculturist, hussar lieutenant, life-saving Roman Catholic, descendant of the historical family Lipthay de Kisfalud et Lubelle did a long way from his home village Lovrin to Szécsény, the one-time land of his ancestors. His life coincided with the disintegration of the historical Hungary, and the most serious trials of the Hungarian society, culture and spirit. These changes affected him as a member of Hungarian aristocracy many times and in fact wanted to destroy him. The fortune of the ancestors have been swept away by the storms of the wars and confiscated but the human strength of character, the consciousness, the talent, the diligence, the sanctuary of faith have remained. All these made him possible to survive, to do his everyday hard creative work, which gained him affection and respect of the people living around him.
Lipthay Béla was mainly lepidopterist and dealt with the the species of Hungary. Place of his collection was first his native country, the Banat, and the area of the Southern Carpatian Montain, and after 1944 Nógrád county (Szécsény, Balassagyarmat, Nógrádszakál, Ipolytarnóc, Rimóc, Ludányhalászi etc.). The collected species belonged to Macrolepidoptera but he dealt also with the moths. During his life time he prepared a collection of 60000 individuals and maintained them until his passing away. Great part of this collection can be found at the zoological cabinet of Natural History Museum in Budapest. He discovered many species new for the Hungarian fauna such as e.g. Cupido osiris (Meigen, 1829), and described a new species (Chamaesphecia sevenari Lipthay, 1961) which later proved to be a synonym of Chamaesphecia nigrifrons (Le Cerf, 1911). He knew well the most famous collectors and specialists of the age. After the first World War he worked together with Frigyes König, László Diószeghy, Jenő Teleki, Norman D. Riley (leading entomologist of the British Museum at London, secretary of the Royal Entomological Society), Brisbane C. S. Warren ( member of the Royal Entomological Society), Lionel W. Rothschild (the most important private collector) and many excellent lepidopterists. After the second World War he was well known and respected by the Hungarian entomologists and lepidopterists: he was a friend of Lajos Kovács, the distinguished lepidopterist and Zoltán Kaszab, the eminent entomologist. He had a good relationship with such renowned Hungarian zoologists and entomologists like Gyula Éhik, László Gozmány, László Issekutz, László Bezsilla and László Móczár. He colleted also Hymenoptera, Diptera and capricorn beetles to be found in Hungarian and foreign collections Natural History Museum, (London), a Szekler National Museum (Marosvásárhely). He dealt with agricultural entomology because he was an experienced agriculturist as far as he had the opportunity to do that. He painted wonderful agricultural entomology posters and organized expositions e.g. on the pests of industrial crops and hunting at Balassagyarmat and Salgótarján.

Cluster, a potential tool for rural development
195-201Views:168There was a heavy change in the characteristics of the agriculture in the last 20 years. It become a multifunctional, sustainable, organic system, which needs strategic approach. On the problem map of the hungarian agriculture the most importatnt questions are the following: dual charachter of the land structure, to occidentalize the farm structure. To develop the rural areas we need to real markets needs adapted, competitive, local agricultural production. From the ’90s into Europe’s economic development policies integrated the clusters, this research tries to certify, that this system is viable in classic agriculture and able to dissolve the defecinces, to support the aims of rural development.

Role of living bacteria and other amendment in early development of maize
53-56Views:122Different bacteria and wood ash, as a possible micro-nutrient, and liming material, was examined in our experiment on the early growth of corn seedlings.
The development of renewing energy resources includes the use of energy grasses and energy forests. The intensive land use in forestry and in agriculture may cause the acidification of soils due to the harvest, or leaching of cations. To maintain the sustainability of soils necessary to maintain it’s the buffer capacity, and pH. Beside the lime the wood ash can is one of the most effective sources to provide the sustainability of intensive land use. The soil born micro organisms play a significant role in the maintenance of soil quality. The bio fertilizer, that contains soil originated bacteria (Azotobacter, and Bacillus sp.), was used in the experiments. The plants release several organic acids by their roots lowering the soil pH, and make more available the sparingly soluble minerals. The amounts of released organic matter depend on stress intensity, as the high pH is. The soil life has a significant role to keep the soil conditions on sustainable level, since there are several similarities in nutrient uptake mechanism between the bacteria and higher plants. Advantageous effects of bio-fertilizer were observed in our experiments.
We came to the conclusion that the use of wood ash is recommended instead of lime for the improvement of acidic soils, on the evidence of its pH increasing effect. The wood ash contains several micronutrients in an optimum composition for forestry and agricultural plants. The solubility of heavy metals is very low; therefore there is no risk to use the wood ash in the agriculture and in the horticulture by our experiments. The retardation of growth at higher ash doses can be explained by the modification effect to the soil pH, as far as the original soil pH was pH 6.8, and when ash was given to the soil, the pH increases to 7.8 pH, that is unfavourable for the uptake of most nutrients.

Name Brands and Symbols Used Organic Products in the European Union and in Hungary
174-180Views:100In 2002, the area which was monitored according to the requirements of organic farming numbered 103 thousand hectares in Hungary (this is some 1.7% of all cultivated land) and almost 1000 plants producing organic products were inspected. It is a realistic assumption, when considering these data, that within a short period time the area used for organic farming will reach the optimal 600.000 hectares.
Contrary to overproduction in the EU – cereals, maize and other plants – organic products can be sold in unlimited quantities. Practice also indicates, that 90% of Hungarian certified organic products are sold in EU and Swiss markets.
Thus, it is important to label Hungarian products according to EU standards. This way standard quality products can be sold easier and by increasing their income, manufacturers can contribute to the improvement of the environment. -
The role of agriculture in regional development
25-30Views:227Agriculture is the leading national economic sector of Hajdú-Bihar county. The proportion of employees in this sector and the share of pro ducts produced in this region is above the country average. The contribution of agriculture to the GDP is 6.3%, as opposed to the average value of the country (3.3%). Based on their primary activity, 8% of the enterprises in the county are classified as agricultural and forestry companies, while this proportion is only 5.3% in the whole country.
Nearly three quarters (71.1%) of the sowing area is occupied by maize and other cereals, mainly wheat. This proportion is slightly more than the country average (69.2%). The proportional area of oil crops - including sunflower – and roughage is nearly the same as the country average. However, there is a significant difference in vegetable production. Due to the higher intensity of vegetable production, the area occupied by vegetables is three times the country average. 19.4% of the crop products, 23.5% of animal products and living animals, 25.8% of the income generated by production factors and 29.8% of net enterprise income of Hungary originates from the North Great Plain region.
The facilitation of creating local markets, e.g. local public food supply, satisfying the needs of food trade with local goods, the necessary awareness raising actions, secondary and higher education of experts, as well as the more specific and targeted utilisation of development resources are agricultural development tasks.

Discussion of an Electronic Examination System in Agricultural HigherEducation
160-163Views:97The development of an internet based electronic examination system at the University of Debrecen Centre of Agricultural Sciences, Department of Land Cultivation and Regional Development was enforced by the dynamic increase in the recent years in the number of students participating in classes taught by the department staff. This paper covers the system’s historical background, the usability factors we were focused on during its development, and the experiences of the testing phase.
The findings of a questionnaire carried out among our students aimed to clarify the acceptance, expectations and fears of future users. -
Effects of the development of production factors on productivity
13-18Views:133In every economic sector, the enacted and expected quality of the products strongly affects its market entry and subsistence. The aim of management is success, competitiveness and subsistence that require adequate human and material resources and enough production stock. We must also notice that the quality of tools and instruments significantly influences work productivity. This applies to both plant production and animal husbandry.
The author researched milk production factors with methodical observation, document analysis and interviews. Data were collected with a ten-year interval, thus this assay can highlight the field, volume and sources of investments during this period and that the production stock increased in most farms and decreased in few. The data also shows the influence of investments on work productivity - there are differences between farms of equal size, so there are still ways of development.

Differences in farmer’s information consumption and ICT-use – a qualitative research
91-98Views:140Farming has now been placed in a new framework: farm managers have had to increasingly devote attention to and interact with the external world. Numerous studies have showed that information and communication technologies (ICT) can play a vital role in realizing benefits with more effective information management at the farm level. Besides land, labour and capital, sufficient information has become a critical factor for agricultural producer. The article presents the findings of a focus-group research which aim was to discover the main characteristics of information consumption and ICT-adoption among Hungarian farmers.

The effect of long-term fertilization on the 0.01 M CaCl2 extractable nutrient content of a meadow soil
73-79Views:103During my research, I studied the 0.01 M CaCl2 extractable NO3--N, NH4+-N, Norg, P and K contents of the soil samples originated from a long term fertilisation trial in the experimental site Hajdúböszörmény. Relationships among the soil nutrient contents, the agronomic nutrient balances of the 2009 year, and fertilization were studied.
From the results of the study it was concluded as follows:
– Fertilization significantly increased the CaCl2 extractable NO3--N, NH4+-N, and K contents of soil.
– Norg fraction increased as a function of the increasing yield. Hence, it can be assumed that the greater the produced yield, the more the stubble and root residues remain on the arable land. These organic residues can result significant increase in the Norg content of soils.
– The CaCl2 extractable P and K contents were compared with the calculated P and K limit values. According to these, the experimental soil has a good phosphorus and lower potassium supply capacity. These results are in accordance with the results of the conventional Hungarian fertilization recommendation system.
– It can be stated that the 0.01 M CaCl2 is able to determine not just inorganic N forms but Norg fraction as well that characterize the easily mineralizable nitrogen reserves. The results proved that AL-P and -K (ammonium lactate acetic acid, traditional Hungarian extractant) are in good agreement with the P and K reserves, but it is important from the aspect of environmental protection and plant nutrition to measure the easily soluble and exchangeable K-, and P-contents of soil. 0.01 M CaCl2 method is recommended for this. -
Effectivity indicators in the German agriculture from the 1990s till today
15-23Views:87Almost fifteen years have passed since the reunification of Germany. At the beginning of the 1990s, it was still unclear how the agricultural sector in the former East Germany would be able to survive, as it was still characterized by large scale farms, organized for a socialist economy. The course of this essay will look at how the agricultural productivity has changed the two different productivity systems in the western and eastern part of Germany.
Productivity can be defined as output produced per unit of input. If we define productivity indicator as output per one type of inputs then we get so-called partial productivity index, however, if we define productivity indicator as output produced per unit of more than one inputs we get multi-factor productivity.
In agriculture, the most often used partials productivity indexes are: labour, capital, land productivity and intermediate consumption productivity.
The analysis of total factor productivity requires the aggregation of all inputs by using input prices. -
Changes in toxic elements content of soil after sewage sludge treatment in energy willow plantation
7-10Views:129The primary purpose of our experiment was the solution of municipal excess sludge treatment by a renewable energy resource used willow (Salix viminalis L.) plantation. Tests were carried out to state whether the applied sewage sludge has caused any accumulation of the toxic elements in the studied soil layers, and - based on the results –to see whether the plantation is suitable for the treatment of municipal sewage sludge.
The excess sludge (sludge before dewatering) is beneficial for the willow, because it contains a 3–5% dry matter and therefore, a lot of water, too. This high water content ensures the high water amount needed for the intensive growth of the willow. On the other hand, the wastewater treatment plant can save the dewatering cost which corresponds to about 30% of the water treatment process costs. The amounts of the sprinkled sewage sludge were calculated on the basis of its total nitrogen content. Treatments were the followings: control, 170 N kg ha-1 year-1 and 250 N kg ha-1 year-1. The mean values of the toxic element concentrations in the sewage sludge did not cross the permitted limits of the land accommodating.The measured toxic element values of the soil were compared to the limits of the 50/2001. (IV.3.) Government Regulation.The sprinkled sewage sludge on the bases of the total N content did not cause accumulation of heavy metals in the soil and the treated plants were also healthy without any signs of toxicity.

Nutritional disorders of arable crop growth in eastern Croatia
273-290Views:149Nutritional imbalances accompanied with growth retardation of crops at early growth stage were found since the last 40 years on certain arable lands in eastern Croatia. In this regard, phosphorus (P) deficiencies in maize and wheat were found mainly on acid soils of the western part of the region, potassium (K) deficiencies in maize, soybean on the hydromorphic neutral to alkaline calcaric drained gleysols of Sava valley lowland, while zinc (Zn) deficiencies were observed mainly in seed-maize and soybean on neutral calcaric eutric cambisols of the eastern part of the region. Cold and moist spring is factor promoting P deficiency symptoms. As oasis of normal crops existed on same arable land, comparison of plant and soil composition was possible from typical sites. P nutrition disorders were in connection with the lower P and the higher aluminum (Al) and iron (Fe) concentrations in the top of plants and the lower soil pH values. K-deficiency as result of strong K fixation and imbalances with high levels of magnesium (Mg) were the main responsible factors of low maize and soybean yields on some drained gleysols. Chlorosis incidences typical for Zn deficiency in maize and soybean were in close connection with the higher soil pH, the lower quantities of mobile Zn, here and there the higher mobile P in soil, the lower concentrations of Zn and the higher levels of Al and Fe in plants. Overcoming the above mentioned disorders and normalization of yields were achieved using ameliorative fertilization either by K or P fertilizers and in case of Zn by foliar spraying of crops with 0.75% ZnSO4 solution. Also, alleviations are possible by selection of more tolerant genotypes of field crops to specific types of nutritional disorders. From this aspect, some practical solutions were recommended for maize with reference to K nutritional problems.

Possibilities of Corn Seed Commercialization on the Hungarian Market in 2003
166-169Views:73According to the sales results of the past two years we can draw the conclusion that although the Hungarian hybrids have very good capabilities, they are still in a big disadvantage in the corn seed sales sector, considering other foreign varieties. These above mentioned disadvantages, as published in prior essays, are not because of the variety’s low quality, but the lack or little presence of marketing. In order to gain position and market on the seed sales sector in Hungary, a lot more has to be done in the area of advertisement.
Seed advertising is very particular and different from all other types of goods. To make growers familiar with your product, you have to be in continuous contact with them, through field days, exhibitions and presentations, besides the well known and in other areas also used quotidian advertisement methods.
Although Hungarian breeders reach better and better results each year, they still cannot catch up with the multinational companies spending millions of dollars on development and advertising, thanks to their financial position.
Finally we can state that choosing the appropriate variety for our needs and possibilities of land and machinery is of great importance in order to reach the best results we can. -
Energy production systems of phototroph microorganisms (classification of photobioreactors)
35-39Views:71In the field of alternative energy sources there is an argue in the comparison of its effects on the benefits and disadvantages to the economics and the environment. New studies are born which are in contradiction with each other. The demand for bioenergy feedstock is growing rapidly however there are the environmental problems caused by the extending energy crop plantations. There is such a significant need for land to grow traditional energy crops on (rape, soy, palm-oil, sugarcane, etc.) that the food purpose agricultural capacity could be in danger. Probably the extensively
growing energy crops play a role in the very high prices of food. In some countries like China for example laws prohibit the use of food based crops such as corn for energie production. In the case of corn based ethanol production the cost only for the feedstock itself is over 60% of the whole preparation costs which significantly effects the entire economy of the energy productions process.
The microalgaes however have a huge biotechnological potential and their production is notably cheaper then the traditionaly grown food crops growing expenses. They play a significant role as feedstocks in todays industrial production in such fields as comestible production, cosmetics, pharmaceutics and biotechnology especially in biofule production. In the field of economy the major aspects here are also the technological designs
and the construction. For the future industrial production the closed type systems seem to have more advantages compared to the open, pond-type systems. For high value material production the more innovative and more easily developed closed photobioreactors are the profitable regardless the vast techological designs used in the construction. -
Comparative examination of the tillage systems of maize on meadow chernozem soil
21-24Views:180Maize production plays a major role in the agriculture of Hungary. Maize yields were very variable in Hungary in the last few decades. Unpredictable purchase prices, periodical overproduction, the increasing occurrence of weather extremities, the uncertain profit producing ability, the soil degradation processes (physical, chemical and biological degradation) and the high expenses are risk factors for producers. Due soil tillage, there is an opportunity to reduce these risks. Based on the experimental database of the Institute of Land Utilisation, Regional Development and Technology of the University of Debrecen, Centre for Agricultural and the KITE Plc., various cultivation systems were examined with maize (Zea mays L.) as indicator plant in Jász-Nagykun-Szolnok country in 2012 and 2013. The sample area can be found in the outskirts of Kenderes on a meadow chernozem soil. On the examined plot, strip-tillage, subsoiling and moldboard ploughing were performed, each on 4.5 ha, respectively.
In general, our findings show, that strip-tillage and subsoiling can be alternative tillage systems beside moldboard ploughing on meadow chernozem soils in Hungary.

Baking quality of winter wheat (Triticum aestivum L.) in the long-term experiments on chernozem soil
152-156Views:92Agriculture 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.
