Comparison of crop production in Hungary and Tanzania: climate and land use effects on production trends of selected crops in a 50-year period (1968-2019)
141-149Views:194A comparison of selected crop production for Hungary and Tanzania is presented. The roles of climate, land use and productivities of crops vary significantly in the two countries. Climate impacts the distribution of crops in Tanzania more than in Hungary as Tanzania’s climate is diverse with hot, humid, semi-arid areas, high rainfall lake regions, and temperate highlands. In contrast, the Hungarian climate is temperate and uniform across the country. Land use changes significantly in Tanzania than in Hungary. Tanzania indicates a reduction in forest land and expanding agricultural land associated mainly with the variation in crop productivities and population growth. To maintain sustainable crop production, increasing crop productivity is of paramount focus to meet the requirements of the growing population.

The milk production and prolification of Saanen goats of various body condition and ages
49-52Views:112In our experiments we tried to find correlation between the age and the body condition of milking goats. We found that these factors significantly incluence the economic parameters of the goats; they have effect on their milk production and reproduction as well. Body condition is the lowest in case of the 3-5-year-old goats, whereas it is the highest in case of the 1-2-year-old. The highest number of kids (2.5) are produced by the 3-5-year-old, while the 1-2-year-old have the fewest kids. Lactation milk production is the highest in case of the 4-5-year-old animals, the lowest in the 1-2-year-old. The lactation period is the longest in case of the 3-4-year old animals in contrast to the younger. The difference is significant in each experiment.

The egg production of hungarian speckled hen and speckled transylvanian naked neck hen
11-15Views:96Our Faculty has been dealing with the cross-breeding of Hungarian speckled hen to maintain the breed since 1977. We keep two breeds of the Hungarian speckled hen, the bare-neck variant and the feathered-neck type on the pilot farm. Because of the spread of intensive poultry keeping the population of these breeds has become endangered. Beside the gene preservation, we endeavour to find the best way for the production-purpose
utilisation of the speckled hen stock. We examined the egg production of these breeds. -
Labour Efficiency of Dairy Farms with Different Types and Sizes in Hajdú-Bihar County
62-67Views:94Questions and uncertainties characterised the accession period of Hungary to the European Union. It is evident that only those producers can compete on the market who produce good quality products. Therefore, only dairy farms with extra high quality raw milk production will be successful. Furthermore, on this basis, rural areas will be able to keep their inhabitants one of the most important problems presently. The author examined the process of milk production and the labour efficiency of 18 dairy farms in Hajdú-Bihar County. Mechanization, the quality of the work force and the system of incentives were assessed. Data of produced milk quality were collected too. Because of farms with different types and sizes the circumstances of milk production differ greatly. As a result of data analysis it was found that the working schedule of small and large farms often differed. The most important working processes (milking, feeding, harvesting) are done by family members. In order to increase the efficiency and improve working atmosphere the improvement of wage and incentive systems would be desirable. Labour efficiency indexes show that the efficiency of tie-stall systems is lower than the efficiency of similar size loose-housing systems. It can also be stated; that labour efficiency of similar size loose housing dairies differs greatly so the importance of work-studies should be increased.

Economic issues of crop based ethanol production for energetic uses
90-94Views:106The United States Congress passed the “Clean Air Act” in 1990, which targeted the creation and use of so-called “green fuel”. This Act came into full force on January 7, 1995. Its essence is that an oxygen rich component is added to fuel by which it burns more cleanly and harmful emissions of vehicles are reduced by 25%. This oxygen rich component is basically ethanol and its ether ETBE, made of domestically produced grains.
America’s traditional grain exporter status could be converted into a stabile income resource during production, many more valuable by-products – should this program succeed – are also produced, giving the opportunity for further utilisation either in the foods or form feeds industries, or as export products.
Ethanol or ETBE production is also important to replace fuel imports from any specific country, the additive which is necessary for producing the fuel is the imported product MTBE.
This programme therefore simultaneously assisted in environmental protection, agricultural and foreign trading issues as well as some market regulation issues. At the same time, based on grain production, it has an effect on the social strata by creating new jobs, especially in those areas which can be considered in recession due to the lack of any large-scale industrial cities.
In the future, the European Union should carry out this project and it will affect Hungary, as well. -
Insect base-protein: A new opportunity in animal nutrition
129-138Views:541The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protein can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.
This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.
The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.
However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

Development of precision apple production technologies in Institute of Water and Environmental Management
97-101Views:257From 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.

Sunflower in Romanian agriculture
153-163Views:227Romania is one of the largest producers of sunflower closely followed by Bulgaria, Hungary, France and Spain. The total sunflower production increased after 1990, due the increase of cultivated surface during the moderate yield average increasing rate. Last year, Romania was ranked first in the European Union (EU) for the area cultivated with sunflower and the total production of sunflower seeds, according to the National Statistics Institute (INS). Romania's position on the map of sunflower producers area is supported by about 1 million hectares sown. In the segment of sunflower productivity, Romania has an unfavourable position, situated in the last places in the classification of the EU's most productive agricultures. In order to increase production per hectare, it is required to perform measures aimed at the elements of sustainable cultivation technology, including the stability of the production level by ensuring phytosanitary protection.

What does precision crop production hold for the future of soil science and plant nutrition?
411-421Views:230The concept of precision agriculture is straightforward at the scientific level but even basic goals are blurred at the level of everyday practice in the Hungarian crop production despite the fact that several elements of the new technology have already been applied. The industrial and the service sectors offer many products and services to the farmers but crop producers do not get enough support to choose between different alternatives. Agricultural higher education must deliver this support directly to the farmers and via the released young graduates. The price of agricultural land must be higher if well-organized data underpin the production potential of the fields. Accumulated database is a form of capital. It must be owned by the farmers but in a data-driven economy its sharing will generate value for both farmers and the society as a whole.
We present a methodological approach in which simple models were applied to predict yield by using only those yield data which spatially coincide with the soil data and the remaining yield data and the models were used to test different sampling and interpolation approaches commonly applied in precision agriculture. Three strategies for composite sample collection and three interpolation methods were compared. Multiple regression models were developed to predict yields. R2 values were used to select among the applied methods.

Organic soybean production in Hungary
45-52Views:222Organic soy production, particularly for feedstuff in organic animal husbandry, is needed in Hungary and the EU regions. Soybean producing crop area in Hungary has increased in the last years, however, the agroecological potential would allow for a larger soybean production area. This study presents the soybean market in Hungary, and the role of soybeans in protein supply in food and feed, summarising the critical elements of organic soybean production from variety selection to marketing. During the field research, the effects of the agronomical environment on yield potential factors were examined. We aimed to determine how different row spacing and tillage systems affect organic soybean yields of different varieties, with particular attention to the dry region, and determine the specific methods and varieties of soybean that favour these areas. We found that the tillage (plough/grubber), the spacing (wide/narrow), and the variety effects were all significant on morphological variables. The most remarkable difference was seen in plant height and the number of pods per plant, while the number of nodes was also highly impacted by tillage treatment and variety. The nutrition variables were significantly different, mainly as an effect of tillage and spacing interaction with significantly different plant responses of varieties.

Climatic water balance in Hamelmalo, Eritrea
69-76Views:216Agricultural production is an important sector for peoples to live, but it is highly affected by climate change. To have a good production we need to understand the climatic parameters which adversely affect production. Hamelmalo, which is located in the semi-arid area of Eritrea, is vulnerable to climate change and this is realised in the total production loss. Nevertheless, there is no concrete reference about the climate of the region due to lack of data for a long time. Changes in precipitation (P), evapotranspiration (ET) and, implicitly, in the climatic water balance (CWB), are imminent effects of climate change. However, changes in the CWB, as a response to changes in P and ET, have not yet been analysed thoroughly enough in many parts of the world, including Eritrea. This study also explores the changes of the CWB in the Hamelmalo region, based on a wide range of climatic data (P, relative air humidity and evaporation pan necessary for computing potential evapotranspiration (PET) with the pan evaporation method) recorded at Hamelmalo from 2015-2019. This analysis shows that the annual cumulative CWB for Hamelmalo is negative in 67% of the years. The dry season without precipitation leads to negative CWB and the change in CWB only starts from the raining or crop season. Based on this recent study, 2015 had the highest PET and lowest P, and this resulted in the lowest CWB in the investigated period. Opposite to this, 2019 had lower PET and highest P, which led to the highest CWB. However, the monthly values of CWB did not correlate with the annual P or ET. On the base of our study, it can be concluded that PET and P were very variable in the investigated years and P was the most influential elements of CWB.

Experiments of sweet potato technology in South Hungary
161-165Views:203The overall objectives of our research program are to examine and to develop the possibilities of use and to expand the national production technology of sweet potato. In 2016, we have set up production technology experiments in many regions, from which we report the results of the experimental field in Deszk here. In our field experiments we obtained results of planting material production, planting and nutrition optimization of sweet potato. Rating the effects of different nutrition doses, between the averages of treatment we didn't experience any significant differencies. On hard soil we set up experimental plots with or without ridges. Based on the result of the harvest the production technology without ridges proved to be more effective. The transplants originating from cuttings from shoots or from tubers did not show significant differences, but it does matter how many tons of sweet potato tubers we harvest per hectare.

Changes in the Diaporthe helianthi Infection of Sunflower Hybrids Between 1998 and 2002
214-233Views:79Plant protection, and especially the efficiency of protection against mycosis, is a very important production technological element concerning sunflower. The efficiency of production can be increased on the basis of a thorough pathological survey and its results carried out in a wide variety of hybrids, as the features of hybrids, the reactions of genetic bases to pathogens can be found out under domestic conditions.
The tests were carried out at variety-test lots of OMMI for hybrids used for food or oil and other sunflower varieties admitted by the state at the Experimental Site DTTI Látókép, Centre of Agricultural Sciences, University of Debrecen between 1998 and 2002. The number of the tested hybrids was 49 in 1998, 45 in 1999, 49 in 2000, 55 in 2001, and 44 in 2002.
Due to the infection source of high amounts remained from 1997 and the favourable weather conditions for the pathogens, an infection of high degree was experienced in the tested stands. The lowest infection index in the hybrids with a very short vegetative period was experienced with Beni hybrids. Comparing to the average of the hybridgroup with short vegetative period, a low infection index characterised the Baleno, Trident, IBH-166, Hysun 321, Resia, Alexandra, Cergold and Pixel hybrids. In 1999, among hybrids with medium vegetative period, Zoltán, Zsuzsa and Util hybrids could be highlighted because of their low infection index. In 1998, among confentionary hybrids, Marica-2 hybrid had the most favourable index values (2,55).
During our trials, the experienced infection dynamics were compared in the event of hybrids with higher and lower susceptibility under different sowing technological elements. The results call for the fact that when a hybrid with higher susceptibility is produced, production technological elements, such as the time of sowing, influence considerably the damage caused by the pathogen, therefore it must not be ignored when its determination takes place. In the event of hybrids with lower susceptibility the change of the tested production technological elements within the biological optimum does not lead to the increased risk of the damage caused by Diaporthe helianthi. -
Connections between land usage, property structure and agricultural enterprises in Hungary
31-34Views:97The last decade of Hungarian agriculture was marked and changes which affected all parts of agricultural production. This process resulted in a new ownership and organisation structure. The paper presents the effects of the changes in ownership on land use and the various enterprise forms and intends to outline the main tendencies. In general, it can be stated that the role of agriculture in GDP production and employment is decreasing in Hungary, but according to concurrent opinions of experts, agriculture still has and will have a major role in income production and the ease of social tensions in rural areas in the future as well. Hungary’s accession to the European Union provides new chances and new prospects for Hungarian agriculture and rural areas. Hungarian agriculture became a part of the internal market which includes about 450 million people. The safety of marketing became stronger, the rate of financial support is increasing and the income of growers will increase in the future. This process implies more obligations and the keeping of strict regulations. Competition inside the internal market is intensifying, competitiveness will be more important while the chances of development and investment of the growers and the feasibility of more effective land use are increasing. After the accession, integration into the directives formulated in the CAP and the packages of measures accepted in it is framework have growing importance.
These directives encourage farm-reallocation, namely the rational estate concentration. In general, it can be stated that rational estate concentration, and more effective land use as a consequence, will increase the efficiency of agricultural production. -
The Role of Cultivation Systems in Quality Sugar Beet Production
134-138Views:137Producing sugar beet, as it is a demanding field crop, has contributed to the raising standard of plant production. It has an outstanding place among the plants that are cultivated in the intensive plant production system. Rentability of sugar manufacture is determined by the stability of yield and the quality (saccharose content) of sugar beet. In this way, the fundamental interest both of the producers and the processing industry is high yield and quality, year by year. The yield and the quality of the sugar beet are mainly determined by the plant production system, so we studied the effect of fertilization, irrigation and plant protection.

The role of type traits of dairy cattles in long productive life
11-18Views:130In the last few decades, a new intensive milking stock has developed as a result of breed-converter crossing in Hungary. Additionally, the reproduction biology of the population was adversely affected by keeping and feeding technologies. Productive lifetime has shortened and the service period has lengthened. However, profitable milk production requires cows with longer productive lives and larger life-time productions. In our study, we made a comparison between production, culling causes, and type traits of culled Holstein Friesian cows after first calving and of cows with a minimum of eight lactations. We established that the first lactation production of cows with longer productive lives was more or less homogeneous. Disease of metabolism as well as digestive and respiratory problems, were the main causes of the culling of cows with short productive lives, and reproduction and udder problems as well as low production, were the main causes of the culling of cows with long productive lives. We found a significant difference in the distributions of strength, body depth, dairy form, croup width, rear leg side view, foot angle, fore udder attachment and teat placement between the two groups. Furthermore, we established that cows with lower stature, less strength, a somewhat deeper body, better dairy form, narrower croup width, smaller foot angle, looser fore udder attachment and some outside teat placement had longer productive lives.

Coherence and connection between the good pond culture practice and the environment conscious management
60-73Views:87According to the data indicating the decline and restructuring during the past decade, as well as the trend in the European Union member states, it can be expected that the role of traditional agriculture and fish production in direct rural employment decrease further. This also values those strategic directions for restructuring that will lead fishculture from quantity driven to quality production along with sustainable development (i.e. environmental conscious production) and multifunctional farming. This way the economic and social tensions caused by the concentration of the production and labour output can be mitigated.
It is laid in the 1257/1999 Act on rural Development that farmers that enrol the agri-environmental scheme should follow the “Good Agricultural Practice” on the whole managed area. In case of agri-environmental schemes this is a precondition for which no grants are given.
The adaptation of “Good Agricultural Practice” in fishproduction,where it is called: “Good Pond Culture Practice” is considered important on the basis of the above mentioned. This programme is undertaken in co-operation with the Research Institute for Aquaculture, Fisheries and Irrigation, University of Debrecen, Faculty of Agricultural Economics and Rural Development and the Association of Hungarian Fish Farmers and Product Council.
The European Commission proposed the formulation of the European Fisheries and Aquaculture Fund (EFAF) for the period 2007-20013, which will replace the Financial Instruments for Fisheries Guidance (FIFG), but it also consists of several new elements and will be working differently, too. According to the proposal the budget for the Fund will be nearly 5 billion EUR (4963 million EUR). The development level of aquaculture and fisheries and the social and economic significance in the given member state will be considered when distributing the Fund between the Member States.
According to the plan the Fund is organised along five priority axes, of which the most important for the Hungarian fisheries sector is No. II: Aquaculture and the processing and marketing of aquaculture and fisheries products. The main measure areas are the followings:
1. investment support for aquaculture;
2. support for aquatic-environmental schemes;
3. environmental- and animal health issues;
4. investments in processing and marketing
In case of accessing support under measure area No. 2 farms are obliged to meet the requirements of the scheme beyond the “good management practice” for 5 years, which is to be supervised by the approved body of the Member State. For this reason our work is considered to be substantial.
Approval of the application of “Good Pond Culture Practice” is based on two elements: first the prevailing environmental and nature conservation regulations, as well as the list of controllable conditions in the new agri-environmental agreements are to be met. “Good Pond Culture Practice” are to be conducted on the whole farm area. Its main elements are:
- nutrition management,
- feeding,
- pond maintenance,
- stocking,
- harvesting,
- animal welfare (storage and over-wintering). -
Using the principles of precision animal husbandry in fishbreeding
283-287Views:263Aquaculture species such as fish, crayfish, molluscs and plats are a wide range of products, with continuously growing demand worldwide. The reasons for this is that they are cheap and easy-toraise protein sources, thus having significance in food supply especially in developing countries in tropic regions, moreover, the premium category foodstuffs in developed high income countries are also belonging to this category. World annual total production of 164 million tons (2009) are made up of two sources: 1) marine and inland fisheries landings that are stagnating for several years and 2) aquaculture which is growing dynamically with annual 6% rate between 2000–2009. The latter is accounting for nearly 45% of the total supply due to the depleting marine stocks caused by overfishing. Aquaculture is growing continuously also because the production is safe and can
be planned well.
Intensive fish production systems are the representatives of precision animal production, several types exist and widespread worldwide. The modern computerized temperate water recirculation plants with several thousand m3 capacity are widespread also in Europe because they make it possible to produce even the most valuable species whole year round. A key issue in the technical/feeding outlay is to meet the demands of the cultured species the best and the operation of the system is to be safe and cost-effective. One condition for this is intensification: enable to produce more product per unit resource input or effort. The facilities need significant amount of energy, thus renewable energy sources are to be favoured for which Hungary has comparative advantages. -
Effects of water deficit on the growth and yield formation of maize (Zea mays L.)
143-148Views:176Maize (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. -
The influence of fertilization and tillage method on the formation root system capacity and grain production of spring barley
89-93Views:136To evaluate the interaction of year x variety, year x tillage method and year x fertilization on the grain yield and root system capacity (RSC) of spring barley, we ran polyfactorial field trials in agroecological conditions of a warm corn production area in Slovakia, at Malanta, in 2009 and 2010. The RSC measurements were done using LCR - meter at a frequency of 1 kHz and they took place in four growth stages: at leaf development in the stage of four leaves (RSC1), in full tillering (RSC2), in the stage heading (RSC 3) and at the stage of ripening (RSC4). The values of grain yield, RSC1, RSC2, RSC3, RSC4 reached in 2009 comparison to 2010 were significantly lower. The highest yield in 2009 was reached by variety Marthe (4.49 t.ha-1) and by variety Bojos (7.19 t ha-1) in 2010. The highest values of RSC in observed growth stages were achieved by variety Bojos in 2009, and in 2010 also besides RSC1. Within both years, difference in yields between tillage methods was not observed. The values of RSC in growth stage of 4 leaves and tillering was higher at conventional tillage, butthe values of RSC3 and RSC4 were higher with minimized tillage. The highest grain yield and values of RSC in every growth stage were achieved on the fertilization variant “c“ in 2009 and on the fertilization variant “b“ in 2010. The correlation relationships between grain yield and RSC were significant and positive in every growth stage. The strongest relationship was found among grain yield and RSC (r=0.6047).

Preparatory studies for modelling production on protected grasslands
64-69Views:179There is a mutual dependence between nature conservation activity and agriculture in Hungary, as the management of the protected areas cannot be achieved without ecological farming methods. Moreover, viable economic activity can be only imagined through the harmonization of agricultural and nature conservation interests. From a nature conservation point of view, grass management systems play the greatest role in domestic agricultural systems. Yet, due to the prohibition of certain management methods and the spatial and temporal restraints on grazing, nature conservation activities have priority on protected grasslands. While nature conservation activity is still of prominent importance, it is not equally suitable for the economical management of protected grasslands per se. With our examinations, we would like to emphasize the common interests of these mutually dependent activities and to promote bilateral cooperation. Our aim is to model the production of grass on the great pastureland of Hajdúbagos. Potential grass production levels are easily calculable with a computer model based on data collected through a series of test harvests, as well as by factoring in changing climatic factors and by simulating the effects of grazing animal species and stocks. This model is not only useful for determining the optimal number of the grazing animal stock and grazing method, and therefore the most suitable management strategy, but it also supports local farmers to be able to plan their activities. In this way, both nature conservation and economic aims can be easily harmonized, which would be an important factor for the sustainable development of rural areas.

Optimization of Density of Sugar Beet (Beta vulgaris L.) Production Quotas by Pointwise Geostatistic Methods
46-50Views:111The regional distribution of the Hungarian sugar beet production quotas was developed by the conventional concurrency relationships. In our research we analyzed 320 sectors of 9 factories with geostatistic methods in a GIS environment. The applied researches of spatial mean, spatial deviation, deviational ellipse have been introduced by us in this speciality. We used two different methods in our optimization inquiries, where the spatial segment of the standard deviational ellipse was based on a more robust preliminary data processing solution, and this is why it is a less parametricable method. The inquiry of the spatial buffer zones in production sectors ensures an obvious optimization possibility. We considered the supply route distances in both cases as a modeling boundary condition. Our results show that we introduced an effective decision making method to the occurent replanning of the production sectors with the pointwise density inquiries and the geometric analogy that was fitted to it.

Significance of biogas production in Hungary
127-129Views:142It is known that the quantity of fossil energy sources are rapidly reducing, therefore it is necessary to determine a new direction which has to point directly to renewable energy sources. Increasingly comes into view the agriculture’s energy producing nature next to it’s traditional food producing one. The enviromental protection is connected to the energy production by the ultilization of biomass for energy purposes, within the biogas production has an emphasized importance. Quasi every organic material can be used in biogas production, such as: food processing by-products, manure, sewage sludge, hoousehold waste.

Effect of facility location on haulage efficiency
204-209Views:91In the 21st century, every economic sector must use the chances of evolution, technical and technological acquisitions, due to the level of competitiveness on the market. Such a sector as agriculture, where technology and the ideology of production are changing and adapting very slow to global expectations, by taking maximum advantage of opportunities, is a more central question. The greatest problems of Hungarian agriculture’s competitiveness are that this sector is very weak in capital and production costs make producers uncompetitive on the market. We can remedy this situation by using sources logically, purposefully and system approached. Logistics can provide the most useful assistance in such efforts.
In agricultural logistics, there is a great deal of uncovered territory. The aim is to transplant methods that are working correctly in other sectors into the agricultural sector, while maintaining development. One of the most important areas is transport logistics and material movement. Methods of analyzing and planning transportation and material movement found in professional literature do not take into account the specific needs of agricultural production. My aim is to examine the effect of facility location in the running of an enterprise. Through the results, I make suggestions for modifying the currently used logistic method and suggest further methods of examination. The effect of agro-specific needs must be examined in carrying out innovations and making logistical planning methods reliable. -
Aflatoxin production on agricultural products
67-71Views:162Aflatoxins due to their toxicity pose significant economic and human health threat; therefore, it is important to avoid this type of contamination in agricultural products. Until now significant aflatoxin contamination occurred mainly in foods of tropical and subtropical origin because the optimal growth of the producer Aspergillus species is between 32–38 ºC. Nowadays the aflatoxin contamination is becoming higher threat in Hungary, due to the imported products, the rising average temperature and the climatic changes. There is a significant knowledge on the genetic and environmental effectors of the aflatoxin production; however, it is remained a great problem to control mold contamination and toxin production in farming and stock-raising. Here we attempted to summarize the knowledge on aflatoxin production and attempts of the elimination.
