Leaf reflectance characteristics and yield of spring oat varieties as influenced by varietal divergences and nutritional supply
29-34Views:99Inadequacy of nutrients in the soil and sufficient inaccessibility to nutrients is caused by factors that affect production and productivity of spring oat varieties. Exogenous application of nutrient and real time nutrient assessment can therefore reverse these associated negative consequences. A field experiment was conducted to evaluate the response of spring oat varieties to sulphur and silicon based fertilisation. Eight spring oat varieties, four level of nutrient application was arranged in a split-plot design with three replications. The obtained results showed that foliar application of sulphur improves the grain yield of most nutrients responsive varieties by about 34.7%. However, application of silicon had shown a diminishing return association to grain yield of variety GK Kormorán, GK Pillangó, Lota, Panni. LAI, thousands grain weight, SPAD, NDVI was significantly (p < 0.05) influenced by genetic difference of the tested varieties, developmental plasticity, and nutrient application. Significantly higher grain yield was obtained from the variety Mv Pehely than the other tested varieties. Therefore, it could be inferred that a combined use of nutrient responsive spring oat varieties and sulphur containing fertilisers could be important agronomic practice to improve grain yield and to develop climate resilient oat varieties.

Quality management and traceability in crop production
273-277Views:148Today, food safety and quality is an everyday issue. Scandals in the food industry drew attention to the role and responsibility of food producers in the food chain. The European Union has set up a new integrated approach towards food safety, to which Hungary as an EU member and export-oriented country has also joined. The new “from farm to fork” principle states that food and feed production cannot be handled separately, as only feed produced from good quality raw materials can ensure safe food products. Another important issue is the traceability of products, allowing for the localization and recall of the defected item. In Hungary, there have been different documentation systems for tracking and tracing products, such as the land register in crop production, animal register in the livestock sector and hygiene registers in the food industry. In order to meet EU requirements, there is a growing number of initiatives to include primary production in the scope of food safety standards. The study introduces and compares the various management systems used in crop production.

Dilemma of interpreting the Tisza space in regional dimensions
169-171Views:110This study deals with the evaluation of an especially important area, since the Tisza river is the basis of the spatial organisation of the Great Plain, the main spatial structural axis of Eastern Hungary and also its ecologic corridor of continental significance. The Tisza is a river which connects five countries to each other and it has an enormous catchment area. Its longest section can be found in Hungary. Two million people live directly in the spatial environment of the river. The safety and favourable quality of life of these people have to be provided. This is a great challenge from the aspect of regional development, economic, technological improvement, the acceleration of innovation processes, as well as the establishment of natural and environmental harmony.

Labour productivity in the Hungarian agriculture
119-128Views:154This paper presents the situation of the agricultural labour employment and evaluates the agricultural labour productivity in Hungary. Since Hungary’s EU accession, the share of agricultural employment in the total employed population has been stabilized at around 5% in the country. Due to low wages, low profit and low prestige, agricultural jobs are not attractive. The gross and net labour productivity gap between Hungary and the EU have been significant since the EU accession. The agricultural labour productivity of the Hungarian regions also shows a different picture. The labour productivity influences the cost, profitability and competitiveness of products. The advantage of the cheap labour force in Hungary’s agriculture significantly decreased due to low labour productivity. There are several opportunities to increase the agricultural labour productivity such as the increase of labour force qualification, moving toward producing higher value added agri-food products, rejuvenation of population in agriculture and the improvement of the conditions of financing agriculture.

Grassland association stock of plants the examination of the regeneration of a construction
185-191Views:35Due to the drastic change in using the nature like grassland association (one-sided overgrazing – one mowing per a year), by the third year of the experiment in every area, where overgrazing stopped, independently on second sowing and nutrient resupply, Borhidi degradation degree decreased. In the areas where overgrazing with large animal density (sheep) continued, degradation degree was 3.4–5.0 by the third year of the experiment, and Hordeum murinum, which causes animal healthy problems, appeared massively.

Studies on Ostrich (Struthio Camelus) - Review
15-22Views:1013Ostrich has been reared in Hungary for decades, but we have limited information on this species. The aim of this review was to provide a concise description of the ostrich (Struthio camelus) based on international studies. We were to investigate some of the most relevant parameters, such as egg, meat and skin production. In this critical review we managed to sum up the most significant features and productivity parameters of ostrich and effecting factors. So as to make an accurate description of the species we have to know its morphological, behavioural and physiological characteristics. Ostrich is a very special bird with special nutritional and environmental requirements. Ostrich products, regarding egg, meat and skin are considered luxury products not only in Hungary but also abroad. Though egg has a significant nutritional value, it is mainly used for hatching chicks. In Europe we can expect roughly 40–50 eggs from a hen yearly. Ostrich has a lean meat with high protein and low fat and sodium content, moreover it is rich in minerals and polyunsaturated fatty acids. Having these advantageous qualities, ostrich meat should be part of our healthy diet. Skin production is not important in our country, but there is a special demand for high quality ostrich leather globally. In the future our aim is to conduct a research on some of the parameters. As low production rate and embryo mortality is a great deal of problem in ostrich industry, we need to investigate the incubation environment. There is an apparent disagreement among researchers on optimal slaughter age. This is also an area for further investigation. The value of skin and effecting factors on our climate as well as adaptability of the species are also worth for further investigation together with the nutrition what differs from other ostrich breeding countries. Nowadays, there is a great emphasis placed on animal welfare too.

Determination of element contents of commercial and homemade jams
71-75Views:251Various products could be prepared by using fruits as raw materials. In Hungary, the most popular fruit products are spirit, jams, preserves, juices and dried fruits. Jams are made from different fruits, with different fruit content, technology and additives. They can be used for different products or they can be consumed by themselves. These products and their related production processes have great traditions in Hungary. In addition, they are widely used.The aim of our study was to determine the element content of jams and to compare these samples based on their micro- and macroelement content.In this study, 26 fruit jams with different botanical origins were examined. 10 samples were commercial, and 16 samples were homemade products. The determination of micro- and macroelements was carried out by using Inductively Coupled Plasma Mass Spectrometer and Inductively Coupled Plasma Optical Emission Spectrometer. Different element contents were measured [B (249.7), Ca (422.6), Fe (259.9), K (769.8), Mg (280.2), Na (589.5), P (185.9), S (182.0), Al (27), Mn (55), Cu (65), Zn (66), Sr (88), Ba (137)]. Based on element contents, the jams showed statistical differences. -
Examination of the plum psyllid (Cacopsylla pruni Scopoli), a vector of European Stone Fruit Yellows (ESFY) phytoplasma in the countryside of Boldogkőváralja (Hungary)
5-11Views:225European Stone Fruit Yellows(ESFY) phytoplasma disease on apricot was identified by molecular methods for the first time in 1992 in Hungary. Currently, the pathogen is known as’ Ca. Phytoplasma prunorum’. Since, the pathogen become wide-spreaded and manyof the apricot-plantations had to be eliminated. In 2009 and 2010 in the countryside of Boldogkőváralja the infection of the apricot-plantations was about 77%. As the disease spreading and causing large damages, we studied the roleo fpossible vector,the plum psyllid (Cacopsylla pruni Scopoli) in the areas of Boldogkőváralja, North-East-Hungary. Studies were done in the year of 2016, monitoring the behaviour of the psyllids in four different areas, and caught 41 them for further examination. We collected plant samples from those apricot trees, on which the plum psyllids were caught.

Results of weed surveys in greening plants
53-57Views:80Greening crops play an essential role in Hungary's agriculture. Weeds can also cause many problems during the development of greening plants. Our research aimed to evaluate the weed control properties of greening crops sown with different germination rates. Analysis of the effect of crop rotations on weed density. Comparison of weed growth in control, fertilised and greened areas. In October of 2021, a weed survey was carried out in lupin (Lupinus albus L.), common vetch (Vicia sativa L.), oil radish (Raphanus sativus var. oleiferus L.) and buckwheat (Fagopyrum eculentum Moench). During the weed survey, we determined the different weed species and their abundance. In terms of seed rates, the higher seed rates for lupin, oil radish, and buckwheat may be worth choosing for weed suppression. Plots in rotation III had the lowest weed incidence of all greening crops. The probable reason for this finding is that there was no prior greening in rotation III. For greening, the choice of buckwheat and oil radish will result in higher weed pressure. The most important weeds were the cereals sown before the greening crop. Fertilised plots had minimally fewer weeds than control plots. Research results show the difficulties of weed control in herbicide-free greening crops.

Special Investment Support Under the Agricultural Reorganisation Programme 1995-2000
64-73Views:75Since the political changes in Hungary, agricultural businesses have worked in a declining economic environment and hectic market situation, with a widening price gap between agricultural and industrial products and low profitability. A declining export comes then by no surprise. The sector has not been able to even benefit from export opportunities provided in the European Agreement. The area least benefiting from quotas is animal products (beef, mutton, lamb, slaughtered chicken, cheese, egg). The ministry of agriculture was lagging behind in responding to these problems, and it was as late as in 1995 when it launched a reorganisation programme for export stocks fund build-up (5).
The author has conducted empirical studies on agricultural enterprises in Csongrád county to see what results the special investment support delivered under the reorganisation programme produced. The fundamental aim of the reorganisation programme for export stocks fund build-up was to boost exportable Hungarian animal product stocks in a bid for businesses to better benefit from the preferential quotas set by the European Agreement. The author examined how the special investment support scheme succeeded in its aims, whether livestock grew considerably in its wake, whether farmers were able to attain exportable quality and what development funds enterprises were able to raise. -
Anaerobe degradation of maize infected by Fusarium graminearum
57-61Views:142Last year intense rainfalls and moisture conditions were beneficial for the Fusarium sp. in Hungary. Fusarium strains decrease cereal quality (for example maize), furthermore may cause yield loss. Due to the toxin production, the fungi have a dangerous animal and human pathogen effect (Placinta et al., 1999).The effects of the Fusarium infection and its mycotoxin production haven’t been perfectly eliminated. Fusariumgraminearum
is the most common agricultural pathogen in Hungary. The utilization of infected maize as an alternative biogas raw material may be an efficient and environmentally friendly disposal method. In this case, Fusarium-, and mycotoxin-content of the maize have to be analyzed as well as the impact of these factors’ on the biogas production process. Our experience was based on the raw material basis of a biogas plant. Different amount of Fusarium free and infected maize grits have been added to the regular raw material mixture. The detection of Fusarium fungi has been analyzed
in experimental digesters throughout the different stages of mesophilic digestion. In the biogas liquid end product the Fusarium was detected by breeding and by microscope. According to our results, the Fusarium sp. was not detectable in the liquid end product after 30 days. -
Evaluation of reduced tillage technologies in corn production based on soil and crop analyses
47-54Views:146Despite new cultivation methods, the proportion of conventionally cultivated land is still very high in Hungary.
Although these technologies demand more time, labour and fuel, they are still attractive to users because they require less professional skill and simple machinery. In Hungary, conventional tillage methods usually lead to soil deterioration, soil compaction and a decrease in organic content. These side effects have caused gradually strengthening economic and environmental problems.
The technologies for those plants which are dominant on Hungarian arable lands use (winter wheat, maize, sunflower and barley) need to be improved both in the interest of environmental protection and the reduction of cultivation costs.
The Department of Land Use at Debrecen University is cooperating with KITE Sc. to carry out soil tillage experiments at two pilot locations to prove tillage technologies already used in the USA.
The aim of our examination is to adapt new technological developments and machinery, and to improve them on Hungarian soil for local environmental conditions. With these improved machines, the field growing of plants could be executed by less manipulation and better suited to economic and environmental needs. The most significant task is to investigate and improve the conventional cultivation replacing, new soil-protecting tillage technologies, and to apply no-till and mulch tillage systems.
On the basis of the experiments’ survey data, we established that the looseness and moisture content of the soil using reduced tillage is more favourable than after using conventional technologies. The results of no-till and shallow spring tillage are behind those of winter plough or disk ripper cultivation in corn yield and production elements.
To preserve moisture content in the soil, the ground clearing and sowing while simultaneously performing no-till method presents the most favourable results. The surplus moisture gained using no-till technology is equal to 40 mm precipitation.
Regarding the yield of winter wheat we established that the tillage methods do not affect plant yield. Both disk ripper and conventional disc cultivation showed nearly the same harvest results (5.55 or 5.5 t/ha), where the difference is statistically hardly verifiable from the no-till method. From the individual production of corn and the number of plants planted in unit area, calculated results prove that no significant difference can be detected between the production of winter plough and disk ripper technology. Although the yield achieved with the no-till method is less than with the previously mentioned technologies, the difference is only 9-10%. We received the lowest production at shallow spring tillage.
Evaluations have shown a 1.1 t/ha (13%) difference in the yield of maize, between winter tillage and the disk ripper method, in this case the traditional method resulted in higher yield. In winter tillage, the yield of maize was 1.9-2.1 t/ha (23-25%) higher than in the case of direct sowing and cultivator treatments. No significant difference could be noted between the yields of direct sowing and cultivator treatments.
Our research so far has proved the industrial application of reduced tillage methods in crop cultivation technologies. -
Nest-site preference of Hooded Crow (Corvus cornix L.) in Debrecen, Hungary
13-17Views:147In the past decade, the population of the Hooded Crow has shown significant growth in Debrecen, Hungary. The aim of this study was to become acquainted with the nest-site selection behavior of Hooded Crows in urban spaces. While our research revealed that the Hooded Crow is not particular when it comes to selecting among tree species for nesting, we did notice differences regarding nesting height. Hooded Crows living in the city build their nests higher up than those living outside Debrecen’s city limits. We also discovered a slight, insignificant difference between nesting heights and tree species, which is probably due to the different characteristics of the given tree species. As for nesting heights, we found that in typical urban habitats there were no relevant differences. However, when we compared these habitats in pairs, it came to light that nesting heights -when comparing solitary trees - wood segments and tree rows - wooded segments- did show significant differences, which can be explained by the various conditions provided by the habitats mentioned.
In summary, the following results emerged from our research:
1. The Hooded Crow prefers approximately the same nesting heights in all kinds of habitats, urban environment and tree species.
2. The nesting height does not significantly depend on the habitat itself or on the tree species. -
Interpretation of the multifunctional agriculture’s function in regional dimensions
177-181Views:107Many branches of science have been examining the concept of multifunctional agriculture. Different interpretations have come into being on global and regional dimensions as well. This study deals with certain interpretations of the concept of multifunctional agriculture. It compares the concepts about multifunctional agriculture of the United States, the Cairns-group, the least developed countries (the LDC-s), as well as the developed countries which import food (the G10), the concept of the EU and Hungary too. It states that the different approaches to the concept have been started by the agricultural problems which are typical of certain areas. These problems have been formed in each and every area by the threefold functions (economic, social and ecological), which are characteristics of rural areas.

Comparative study of different soybean genotypes in irrigation technology
91-95Views:283In many places in Hungary, early maturity soybean can be successfully grown. The earlier maturity group of soy which ripened in 110–125 days in most crop areas in Hungary. However, to achieve excellent results, the selection of proper varieties is important too. Successful cultivation is largely dependent on the macro and microclimate of the production area, the nutrient supply of the soil and the cultivation technology. Soybean can be produced in places where the amount of precipitation is right, as the lack of water results in lower yields and deteriorated oil and protein concentrations. In the following study, 2 years (2016 and 2017) are compared to the yield, protein and oil content of the soybeans of the early maturation group in irrigated and non-irrigated treatments. Based on our experiment, it can be stated that, during the irrigation of soybean, oil and protein content and yields did not always change.

From Lovrin to Szécsény – remembrance to Béla Lipthay (1892-1974)
21-32Views:79Béla 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, confiscated by the beneficiaries of tricky ideas of the new age and decimated by practical swindlers, but the human strength of character, the consciousness, the advantage of education and the with them associated ability, diligence, inventiveness and the sanctuary of faith have remained. All these made him possible to survive, to do his everyday hard creative work, which gained him the affection, the esteem and respect of the people living around him.
Protecting his remembrance we evoke his many-sided, altruistic efforts for the Hungarian people and Hungary, and we can contribute to the creation of a better and just world. -
Long-term experiments on chernozem soil in the University of Debrecen
357-369Views:225The impact of agrotechnical management practices (nutrient and water supply, crop rotation, crop protection, genotype) on the yields of winter wheat and maize and on the soil water and nutrient cycles was studied in long-term experiments set up in 1983 in Eastern Hungary on chernozem soil. The long-term experiments have shown that nitrogen fertilizer rates exceeding the N-optimum of winter wheat resulted in the accumulation of NO3-N in the soil. Winter wheat varieties can be classified into four groups based on their natural nutrient utilization and their fertilizer response. The fertilizer responses of wheat varieties depended on crop year (6.5–8.9 t ha-1 maximum yields in 2011–2015 years) and the genotypes (in 2012 the difference was ~3 t ha-1 among varieties). The optimum N(+PK) doses varied between 30–150 kg ha-1 in different crop years. In maize production fertilization, irrigation and crop rotation have decision role on the yields. The efficiency of fertilization modified by cropyear (in dry 891–1315 kg ha-1, in average 1927–4042 kg ha-1, in rainy cropyear 2051–4473 kg ha-1 yield surpluses of maize, respectively) and crop rotation (in monoculture 1315–4473 kg ha-1, in biculture 924–2727 kg ha-1 and triculture 891–2291 kg ha-1 yield surpluses of maize, respectively). The optimum fertilization could improve the water use efficiency in maize production.
Our long-term experiments gave important ecological and agronomic information to guide regional development of sustainable cropping systems.

A growth model to predict body weight and body composition of broilers
17-24Views:339Models predicting the nutrient partitioning and animal performance have been developed for decades. Nowadays, growth models are used in practical animal nutrition, and they have particular importance in precision livestock farming. The aim of the present study was to introduce a broiler model and to provide examples on model application. The model predicts protein and fat deposition as well as the body weight of an individual broiler chicken from digestible nutrient intake over time. Feed intake (FI) and the digestible nutrient content of the feed are inputs as well as some animal factors like: initial BW, feed intake at 1 and 2 kg of BW, precocity and mean protein deposition. The protein and energy metabolism is represented as in the classical nutrient partitioning models. The protein deposition (PD) is driven by digestible amino acid supply and is under “genetic control”, the so-called potential PD limits the actual PD if protein is oversupplied.
The authors discuss how the model can be used to simulate the animal response upon different scenarios. Examples are given to show that the diet might be limiting if some animal trait is changed. Applicability of the model has shown through running the model by using different feed strategies (three- vs five-phase-feeding) and variations with animal factors. In conclusion, growth models are useful tools to support decision making for defining the most suitable feeds used in a broiler farm. The model presented in this paper shows a high sensibility and flexibility to test different scenarios. By challenging the model with different inputs, the animal response in terms of changes in body weight and feed conversion can be understood more by studying the shift in deposition of chemical constituents. The examples provided in the present paper shows the benefit of using mathematical models and their applicability in precision nutrition. It can be concluded that the growth model helps to apply “from desired feed to desired food” concept.

Yield table for selected black locust (Robinia pseudoacacia L.) cultivars
193-198Views:179In Hungary, the black locust (Robinia pseudoacacia L.) can be considered as the most important fast-growing, stand-forming introduced tree species. Due to its positive growing technological characteristics as well as wood utilization possibilities, at the present, black locust is the most widely planted tree species in Hungary, covering 25% of the country’s total forest area. One of the important tasks ahead of Hungarian black locust growers is to improve the quality of black locust stands with introducing selected cultivars. For the estimation of the growth rate and yield a numerical yield table has been constructed on the basis of surveys of the experimental plots established in pure,managed ’Nyirségi’ ,’Üllői’ and ’Jászkiséri’ black locust cultivars’ plantations which can be suitable for sawlogs production. In the course of 56 stand surveys the key stand characteristics were measured, and then, were reconsidered the average height, diameter (DBH), volume, basal area and stem number given separately for the main (remaining), secondary (removal) and total stands per hectare. The programmable editing procedure allows to extention and formal change of information content of the yield table according to different demands.

Technological and Economic Analysis on the Hungarian Rice Sector
226-233Views:76Hungary lies on the northern edge of rice production area. According to this, the climatic conditions area not perfect for this species. The production area of rice involves typically the poorer quality soils, however these meet the requirements of rice. In Hungary exclusively domestic types are grown which have high yield and good quality and these are usually wore successful than foreign types. On the other hand, these Hungarian types should be improved considering safety in production. Nowadays, rice is grown in large scale companies with 300-1400 hectares, where production technology already exists, machinery is suitable, however the latter one a little bit old.
The average yields of the analysed companies were 3-4 t/ha in the past few years, which were a little bit above the national averages. The operating cost per hectare is almost 200 thousand HUF, from which the main part is the cost of machinery (35%) and the material cost (34%). The main part of the latter one is the irrigation costs (30%). The average cost, calculated from the total production cost, is 80 thousand HUF/t. Considering the above-mentioned costs and the price of rice (75 thousand HUF/t) it can be stated that the profitability of the rice sector is not the best, the cost rated profitability is -6.6%. According to the results of this analysis possibilities for the increase in profitability and improvement are increased subsidies and market price, as well as genetic improvement. -
Research on rheological characteristics of winter wheat varieties
266-272Views:140The gluten examination test is dominant in Hungary, comparing it to the qualification system of other countries. The determination of alveographic parameters is a basic criterion of winter wheat specifications in some western and southern European countries.
In the Hungarian and foreign winter wheat qualification systems, in the standards, there is no limit for extensographical parameters. Customers dictate the limits and make their claims as to the specifications.
We analyzed the alveographic and extensographical parameters of 19 winter wheat varieties grown by the Cereal Research Non-Profit Company in Hungary, and we made a comparison between the results in the challenges of the European Union expectations.
Examining the information of alveographic and extensographical values, we found that the experimental varieties provide high base to flour types suitable for baking bread and baker’s ware. The GK Élet, GK Petur, GK Memento, GK Csillag, GK Kapos and GK Marcel varieties can meet the market of paste flour needs, too.
In the variety series, the GK Kalász represents the highest values and the GK Garaboly shows the lowest parameters regarding the alveographic W and the resistance to extension.
On the basis of relation, we can establish that we can estimate the following little known and used quality indexes: the extensographical resistance to extension with extensographical energy and the alveographic W value, the extensographical energy with the alveographic W value and the alveographic P and L values with the other alveographic parameters. -
Amelioration and arable land-use possibilities of Solonetz soils in the Trans-Tisza region of Hungary
107-117Views:176Salt affected soils cover about 1 million hectares in Hungary. This paper is based on the research results obtained at the Karcag-puszta long-term experimental site, where, depending on the catena, crusty (A horizon=0–7 cm), medium (A hor.=8– 20 cm) and deep (A hor.>20 cm) subtypes of the Meadow Solonetz soil could be found. The chemical reclamation was made specifically for the given site. Lime was applied on the soils with neutral or slightly acidic top layer, while on the soils with alkaline top layer, gypsum was applied. As regards internal drainage, a tube system with an average depth of 1 m and 5, 10 and 15 m drain spacing was constructed. Decreasing salt and sodium content could be measured both in drained and non-drained soils. The advantage of drainage was that the leachingout extended to the whole layer above the drain pipes, while without drainage, the Na ions exchanged from the upper layers still accumulated at a depth of 60– 100 cm. In the first two decades, the groundwater level was deeper and leaching was the dominant process. Since 2004, due to the frequently high groundwater level, the leaching and deepening of the fertile top layer has been slower.

The effect of plant density to the yield results and the yield components of maize hybrids
89-93Views:135Maize is the crop that is produced on the second largest area in our country, in Hungary. It is planted on nearly 25% of the country’s growing area and it was produced on 1 090 439 hectares in 2016. Despite the continuous development of the biological basis and production
technology, the growth of the yield results is not constant, its fluctuation is significant. It can be even up to 60%, because of the extremity of the years. The exploitation of the yield potential of modern hybrids is possible if we harmonize the effects of the ecological factors and properly applied instruments of agro technology and by these we ensure their interaction to reach a favorable outcome. The applied plant density is an important, well researched, but at industrial level a not enough utilized element of the maize production.
The results of the extensive tests, done between 2009 and 2015, showed that the genotype, the year effect and the plant density are in strong correlation with each other determining the yield results. In the past seven years the examined genotypes reached the highest yield
performance at the highest plant densities. The early hybrids (RM90–95, FAO 200–300) are capable of producing them at higher plant density, while in case of the mid and late maturity varieties the further increasing of the density after reaching the optimum level led to yield depression.
According to our experimental results, the yield is in close positive correlation with the increase of the plant density. The effect of the growing season has great significance in forming the yield results and this determines the applicable plant density too.
The yield of maize is determined by a resultant of components. The main component is the number of ears per plant and the amount of kernels per ear, which is calculated from the number of kernels on an ear and the weight of them. The number of the kernels on an ear is
calculated from the number of rows on the cob multiplied by the number of seeds in one row on the cob. In dry years, at lower yield levels the yield decreases because of the shorter ears, while at the higher levels the number of kernels in a row and the thousand-kernel weight decreases,causing yield depression this way. From our examinations it turned out that the plant density reaction of a genotype is individual, every variety reaches its maximum kernel number per hectare – in other words the maximum yield - in an individual way. -
The Situation and Prospects of Hungarian Rural Development Preceding EU Accession
224-231Views:83Today’s Hungarian rural development is defined by the fact, that Hungary will be a member state of the European Union from May 1, 2003. Our accession means the end of a long period, and new rural development programs that are going to build on the basic of previously accepted EU standards and experience will highlight the immediate future.
From the Hungarian rural development programs I especially dealt with the SAPARD, AVOP and NVT, which in my opinion had and will have the greatest influence on the improvement of the Hungarian county. The AVOP and NVT are still under development (or just submitted to the EU), but their role in the future will be particularly essential, because these programs are going the act as the first programs in Hungary as a member state and a lot will depend on them in the improvement of the rural development. -
European Funds and the Evaluation of Their Application in the Northern Great Plain Region
191-198Views:77Presently, the process of regionalization is slowly progressing in Hungary. The regional institutional system is young and the institutional experiences are limited. The Hungarian regional development agencies are operated with a limited number of personnel and their budget is only a fraction of EU regional agencies of similar size. There is no unequivocal cooperation between regional development agencies and county development agencies. In the absence of these, the strategical objectives of the region cannot be aligned and the application of consistent development policies cannot be achieved. In the past five-six years the supports from EU Pre-Accession Funds, along with the new tools of regional development policies, have all contributed to the development of the North Great Plain Region. Phare projects – beside supporting development – have played a significant role in forming the approach of individuals who are actively involved in regional development, in promoting cooperation among cross-border and other regions, as well as in preparing the regions to accept EU structural funds. Prior to the May 1st, 2004 EU accession of Hungary, the North Great Plain Region received 24-25% in direct regional development funds in the Nineties. The support per capita in the case of TFC, TEKI and CÉDE has exceeded the national average. The North Great Plain Region has received support from investment type agricultural supports, the Employment Fund and the Touristical Directives that well exceeded the national average, from the sectoral resource funds. However, the applicants of the North Great Plain Region have received little support in the case of environmental, water management and especially road development supports. About 200 applications have been submitted for the SAPARD calls nationally, 32 of these were from the North Great Plain Region. The significance of cooperation among sub-regions is demonstrated by the fact that, except for 15 settlements in Szabolcs-Szatmár-Bereg county, all have submitted an application. The efforts of inhabitants is highlighted by the high number of submitted applications, as well as by the significant degree of own contribution. Still, the GDP of the North Great Plain Region has not increased, the rate and tendency of unemployment does not sufficiently reflect the positive effect of supports. The Regional Development Directive has provided support for the development of many small- and medium size enterprises, but their effect did not ensure a sustained economic growth.
The greatest difficulty is that the number of dedicated professionals who are skilled in regional politics and regional development is few. However, advantages of our EU accession can only be exploited if a group of highly skilled professionals is provided on local, county, regional and national level as well. Thus, we need a group of professionals who are informed about the European Union, the EU support forms and most of all about the operation of Structural Funds and Cohesion Funds to establish the suitable institutional background for professionally handling the funds obtained from the EU, to prepare the professional documents to access the funds and to generate development projects to efficiently use the funds as well as establishing connections with the institutions of the EU. Appropriate share from funds coming from the EU is only possible if the country, certain regions, counties and sub-regions can achieve rapid results in the areas listed above.
