Spatially Discrete GIS Analysis of Sampling Points Based on Yield and Quality Analysis of Sugar Beet (Beta vulgaris L.)
32-37Views:427Fulfilment of the increasing quality requirements of sugar beet production can be analysed with sampling of plants and soil at the cultivated area. Analyses of the spatial characteristics of samples require exact geodetic positioning. This is applied in practice using GPS in precision agriculture. The examinations were made in a sample area located in north-western Hungary with sugar beet test plant. According to the traditional sample taking procedure N=60 samples were taken in regular 20 x 20 m grid, where besides the plant micro and macro elements, the sugar industrial quality parameters (Equations 1-2) and the agro-chemical parameters of soils were analysed. Till now, to gain values of mean, weighted mean and standard variance values, geometric analogues used in geography were adapted, which correspond to the mean centre (Equation 3), the spatially weighted mean centre (Equation 4), the standard distance (Equation 5), and the standard distance circle values. Robust spatial statistical values provide abstractions, which can be visually estimated immediately, and applied to analyse several parameters in parallel or in time series (Figure 1). This interpretation technique considers the spatial position of each point to another individually (distance and direction), and the value of the plant and soil parameters. Mapping the sample area in GIS environment, the coordinates of the spatially weighted mean centre values of the measured plant and soil parameters correlated to the mean centre values showed a northwest direction. Exceptions were the total salt and calcium-carbonate contents, and the molybdenum concentration of the soil samples (Table 1). As a new visual analysis, the spatially weighted mean centre values of the parameters as eigenvectors were projected to the mean centre values as origin. To characterize the production yield, the raw and digested sugar contents of the sample area, the absolute rotation angles of the generated vectors were determined, which indicate numerically the inhomogenity of the area (Figure 2). The generated spatial analogues are applicable to characterise visually and quantitatively the spatial positions of sampling points and the measured parameters in a quick way. However, their disadvantage is that they do not provide information on the tightness and direction of the spatial correlation similarly to the original statistical parameters.

Consumption of fertilizers in districts of Slovakia in the period 2006–2015
389-398Views:300Consumption of fertilizers in districts of Slovakia in the period 2006–2015 Water quality in the surface streams is influenced by several factors. One of important information which can help us to solve problems with quality of water in water body is a distribution of point and non-point pollution sources in a river basin and also amount of pollutants released from them to surface streams. An example of a point source of pollution is the outlet from wastewater treatment plants (industry, urban areas, farms, etc.). On the other hand the most significant non-point source of pollution is considered the application of fertilizers in agriculture.
In this paper we have evaluated consumption of organic and industrial fertilizers in Slovakia in the period 2006–2015. Total (in tonnes) and average (in kg ha-1) consumption of industrial and organic fertilizers was analyzed. In monitored period, the amount of applied organic fertilizers was much higher than the amount of applied industrial fertilizers and in addition a significant part of total fertilizers consumption had nitrogenous fertilizers in a group of industrial fertilizers. In a group of industrial fertilizers during the period 2006–2015 we observed just moderately increasing in their consumption, while in the period 2010–2015 the average amount of applied industrial fertilizers per hectare of agricultural land increased by about 20 kg ha-1. On the other hand, in a group of organic fertilizers we observed a decreasing in consumption of fertilizers.

Does drought stress always negatively affect the yield and quality of soybean in Hungary?
37-40Views:493Globally-fluctuating climate imposed serious abiotic stresses on the agricultural sector, leading to noticeable, and sometimes disastrous, losses in yields and/or quality of crops; however, in certain cases, plants could survive stress with relatively low reductions, and sometimes even with some enhancements as a reaction to changed environment, especially in the case of mild stress. An experiment was conducted in 2017 and 2018 in Debrecen, Hungary to evaluate the mild drought stress influence on the yield and quality of three soybean cultivars. The results showed that both ES Pallador and Pedro cultivars could achieve more yield when subjected to mild drought conditions; however, protein concentration was enhanced in ES Pallador whereas slightly degraded in Pedro under drought. The cultivar Pannonia Kincse followed different trend; both yield and protein concentration were reduced under drought. Oil concentration of the three cultivars did not show significant changes; however, it always followed opposite trend to that of protein concentration. It could be concluded that both ES Pallador and Pedro are recommended to be grown under rain fed conditions in Debrecen, whereas Pannonia Kincse is recommended under irrigation conditions.

The Impact of Water Supply on the Quality and Health of Potato
144-147Views:407Besides its effect on potato yield, water also has a significant impact on yield quality. Excess water (too much precipitation, over-irrigation) and the lack of water (lack of precipitation or irrigation) both trigger stress in the plant and can significantly worsen the quality of the yield (seed potato) and deteriorate the health of the plant and the seed potato. Excess precipitaton or irrigation water leaches nitrate-nitrogen under the rhizosphere, consequently, the amount of available nitrogen decreases leading to the deficiency of N in potato. If water cover (the maximally saturated state of soil) exceeds 8-12 hours, it can cause root destruction (because of the lack of oxygen), which leads to the wilting and later to the death of the plant. Abundance of water caused by excess precipitation or irrigation is a major problem primarily on sandy loam, loam and clay loam soils with bad structure and water management qualities, but also on any soils, which are over-irrigated or irrigated at an improper time. Symptoms of the lack of water are detectable mostly when the available water content of the soil (disponible water) decreases under 60-65%.
In the present year, there was a lack of precipitation on the Great Plain, which can be compensated by proper irrigation. Unfortunately, this problem is further intensified by the high temperature, which results in faster ripening and accompanied with fluctuating soil moisture content, in the formation of secondary tubers. -
The effect of keeping technology on the microbiological status of raw milk
67-75Views:561The importance of the quality of raw milk increased after Hungary had joined to the EU. On delivery of raw milk, the microbiological quality, especially total plate count of the milk is very important. Twenty-two farms (7 large, 4 medium-sized, and 11 small farms) were included in the study. We considered the different farm size, keeping- and milking circumstances during the selection of farms. The examined large farms use loose housing system (cubicle, deep litter) and milking parlour. Most of them use preand post-milking disinfection. In the medium-sized farms, loose,
deep litter and tie-stall housing system, as well as milking parlour, pipeline milking and bucket milking occurred. All of them use preand post-milking disinfection. Small farms use tie-stall housing system, bucket milking and udder preparation by water. Unfortunately, they do not use pre- or post-milking disinfection. In the large and medium-sized farms mainly Holstein Friesian, in the small farms Hungarian Simmental breeds can be found.
The aim of our research was to examine the microbiological status of the raw milk produced in dairy farms (total plate count, coliform count, Escherichia coli count, Staphylococcus aureus count, psychrotroph bacteria count, furthermore yeast and mold count); sources of the contamination; connection between the microbiological quality of produced milk and housing-, milking technologies of farms; furthermore the hygienic circumstances of milking and milk handling of the farms, by the examination of coliform bacteria and Escherichia coli contamination.
During the examination of the connection between the different farm sizes, various housing- and milking forms and the microbiological characteristics we observed similar tendencies in the case of total plate count, coliform count, yeast and molds count, furthermore psychrotroph bacteria count. The value of these parameters was significantly higher in small farms, and infarms which use tie-stall housing forms, bucket milking, udder preparation with water, and which do not use pre- and post-milking disinfection.
The results showed that besides cooling, the milking procedure and the type of udder preparation had the largest effect on the total plate count. Statistical analysis shows that in medium and small farms the combination of pipeline milking – tie stall housing system – disinfectant preparation of the udder; in large farms the combination of milking parlour – loose cubicle housing system – dry preparation of the udder are the most appropriate in the aspect of the total plate count. We experienced that in farms where the hygienic instructions are not followed – and therefore
equipment used during the milking and handling of milk is very contaminated – or rather the separation of mastitic cows’ milk is not appropriate, different microorganisms may contaminate the produced milk. -
Determining factors of test weight in maize (Zea mays L.)
40-42Views:418Most domestic maize production products are sold on markets abroad. Among the increasingly restrictive quality requirements, the demand for the measurement of test weight has also appeared. This measurement is not unfamiliar in the case of other cereals, such as wheat and barley, but it has not been applied widely in maize. It is likely for this reason that we have such little information and research available on this topic. In this study, we show the current state of this field with references from domestic and international literature.
The density of maize is the weight of a particular volume and the most frequent unit is the test weight (kg/hl). This physical quality factor plays important roles in the storage, transport and mill industries. The value of test weight is influenced by many factors. The most important ones are the moisture content of grains, drying temperature, drought, precipitation, early frost, and the hybrid characters of a given genotype (grain type, FAO number). In general, the grain with higher moisture content has lower test weight and the higher temperature during (above 82°C) desiccation also leads to unfavourable values. Factors such as a drought interval after flowering, early frost in the case of hybrids with higher FAO numbers, injuries by insects, as well as fungal infections also influence the structure and moisture content of the maize grain.
In the future, broader studies (hybrid testing, application of new agrotechnical elements) will be needed for understanding of the factors effecting test weight. -
Research on seeding agents to effect the sugar crystallization
30-33Views:182The quality of sugar is the decisive factor in ensuring the sugar commercializing through the conservation of old markets and
expansion towards new markets. The sugar quality is also the key element which determines the price maintenance in according with the
expenditures performed or even the diminution of the price as a consequence of the quality lessening. -
Effect of Auxin-Synergistic Preparation and Fertilization on Fruit Setting and Fruit Quality ofApple
21-26Views:328On seven apple cultivars (Gala Must, Gloster, Granny Smith, Idared, Jonagold, Jonathan Csány and Mutsu), the author studied the influence of N-phenyl-phthalamic acid (Nevirol 60 WP) and fertilization on fruit setting and fruit quality.
The research results show that by using Nevirol 60 WP and applying fertilization, we can improve the fruit setting and number of fruit per tree. As a result of this process, the yield amount will increase.
Nevirol 60 WP has a great effect on the improvement of yield amount, especially by good nutrient supply. There is a significant difference between the reactions of different cultivars. The most sensitive to these treatments were the cultivar Gala Must and Granny Smith. Before using Nevirol 60 WP we have to take into consideration that the increased yield needs a higher nutrient supply; otherwise, fruit mass, diameter and fruit height will decrease, and the yield will frittered away. In the study, the most favourable effect of Nevirol 60 WP was detected under additionally fertilized conditions by the author. -
The comparison of sperm motility and density in four different goldfish (Carassius auratus) types
135-140Views:377Different goldfish types play an important role both in ornamental fish farming and science. Considering its historical background, the goldfish is a suitable model animal for the study of artificial selection as well as for developmental biological studies. Sperm motility and cell density is an important parameter in determining sperm quality. The aim of our study was to examine the effects of different goldfish types on the sperm quality. Several sperm motility parameters (progressive motility (pMOT, %), straight line velocity (VSL, μm s-1), curvilinear velocity (VCL, μm s-1), linearity (LIN, %), amplitude lateral Head Displacement (ALH, μm), Beat Cross Frequency (BCF, Hz)) of four different goldfish types (Common goldfish-“wild type” N=5, Shubunkin N=4, Black Moor N=4, Oranda N=5) was compared during 60 hours (at 12-hour intervals) at refrigerated storage (4 °C). The variability of sperm density was also investigated in all types. A similar cell concentration was determined in the four goldfish variants (Common goldfish 2.01*1010 ± 3.46*109; Shubunkin 1.71*1010 ± 3.25*109; Black Moor 1.66*1010 ± 3.02*109; Oranda 1.56*1010 ± 5.83*109). Statistically significant difference between the 4 goldfish types in the motility parameters and cell density was not noted. However, a decreasing tendency in Black Moor sperm motility parameters (pMOT, VCL and VSL) was observable, as well as a reduced spermatozoa density in Oranda was also recorded. Our results can contribute to the improvement of the common hatchery propagation of goldfish. Future studies can add more evidence of the possible effects of artificial selection on the reproduction in different goldfish types.

The effect of short term storage on different winter wheat varieties rheological properties
83-86Views:897The aim of storage after harvest is to protect the quality of wheat, because after-ripening occurs in the first 5–6 weeks. During this time it very important to make the optimal storage conditions.
We have carried out storage experiment with wheat samples from Látókép Research Farm of the University of Debrecen. We analyzed the rheological parameters of Lupus and GK Csillag varieties from the crop year 2011/2012. The experiment period was between July and August 2012 (24. 07. 2012., 31. 07. 2012., 21. 08. 2012.).We determined the rheological parameters (water absorption, dough stability time and valorigraph quality number) of Lupus and GK Csillag during short term storage. Our results showed that after-ripening increased the baking quality of Lupus and GK Csillag during storage.

117-120Views:539Honey is one of the oldest known and consumed food. Besides the pleasant sweet taste it has been consumed because of the favorable health benefits. In addition to large number of honey plants there are many popular herbals which cannot serve as a nectar source. The herbhoney has been developed that consumers can joy the pleasant properties of herbals and honeys positive impact on the same product. In our research we compare the quality parameters of honeys and herbhoneys to each other and with the relevant regulation.

Evaluation of the use of leaf fertilizers and growth regulators in winter wheat: A review
77-82Views:482Winter wheat is a leading cereal on a global scale, however, yields remain variable due to increasing weather extremes. This review synthesizes evidence (1971–2024) on the effects of foliar fertilizers and plant growth regulators/biostimulants on wheat growth, yield and quality. Across studies, appropriately timed foliar micronutrient applications (Fe, Mn, Cu, Zn, B, Mo) tend to enhance chlorophyll content, photosynthetic activity, and grain quality traits, while selected copper- and zinc-based products frequently increase grain yield and crude protein. Biostimulants—such as amino acids, humic/fulvic acids and seaweed extracts—generally improve stress tolerance (drought, cold) and may raise grain number and thousand-kernel weight. Plant growth regulators (e.g., lodging control agents) can reduce plant height, strengthen stems and improve stand stability, thereby contributing to yield security. Evidence magnitude varies with soil supply, cultivar, and phenophase-specific timing. We summarize practical windows of application, expected responses, and limitations, and highlight research gaps in standardizing doses and reporting effect sizes. Overall, foliar nutrition and growth regulation are promising tools to increase yield stability and quality under increasingly variable growing conditions.

Crop Load, Fruit Thinning and their Effects on Fruit Quality of Apple (Malus domestica Borkh.)
29-35Views:755Crop load, a quantitative parameter used by industry, is generally defined as the number of fruit per tree. It is often expressed in terms of number of fruit per trunk cross-sectional area (fruit/TCSA). Crop load is the most important of all factors that influence fruit size, and the removing of a part of the crop is the most effective way to improve fruit size.
The potential size of a given pome fruit is determined early in the season and growth proceeds at a relatively uniform rate thereafter. This uniform growth rate permits the accurate prediction of the harvest size of the fruit as early as mid-summer. The growth rate, once established, is not easily altered, and fruit numbers, therefore, can affect fruit size only within definite limits and maximum effectiveness requires adjustment in fruit numbers relatively early in the season. It was established, that „thinning does not change a potentially small fruit into a large fruit, but rather insures that a potentially large fruit will size properly.” Emphasis should be on estimating fruit numbers rather than fruit size.
Fruit thinning can quickly reach the point of diminishing returns. Rather than a high percentage of large fruits, the objectives of thinning should be the elimination of the smallest fruits, improved fruit quality and annual production. Fruit thinning is accomplished by hand or chemical thinning. Chemical thinners are separated into categories as bloom thinners and post-bloom thinners. Early removal of potential fruit (blossom thinning) is currently used in many apple producing areas to enhance flower initiation for next year’s crop and thus, return bloom. It also results in reduced competition for photosynthates. Blossom thinners usually have a caustic effect on floral parts.
The amount of fruit left on a tree should be determined by the vigor and general condition of the tree. Leaf area per fruit affects the number of spurs flowering the following season. It can be difficult to separate timing and fruit number effects in crop loading studies, as abscission rates after hand thinning of retained flowers/fruitlets tend to very with the time of hand thinning. -
Influence of nitrogen fertilisation on the technological quality of wheat
47-55Views:425Wheat is one of the most grown crops around the world. Its primary use is in the production of bread, bakery, and confectionery. The provision of essential nutrients, mainly nitrogen, plays a pivotal role in the growth and development of wheat. The wheat varieties used in the experiment are Alfold and Mv. Menrot. The rates of nitrogen used in the experiment are: 0, 200, 400, 600, 800, and 1000 kg N ha-1. The aim of this study is to evaluate the effect of nitrogen fertilisation on technological quality of wheat and to find the appropriate fertiliser rate to reduce pollution. The results indicate that nitrogen fertilisation did not show a significant effect on thousand kernel weight and test weight. However, nitrogen fertilisation significantly affected protein content, gluten content, Zeleny sedimentation index, and the falling number. The higher the nitrogen fertilisation the better the technological quality parameters of the wheat. The protein content, gluten content, Zeleny sedimentation index and the falling number were the lowest at 0 kg N ha-1 followed by 200 kg N ha-1 then 400 kg N ha-1 and the highest at 600 kg N ha-1.

Agronomic bases of precision barley production
217-220Views:243To ascertain the importance of individual preciosion factors in achieving yield and quality of malting barley, we established a multifactor
experiment at the research station of the Slovak University of Agriculture in Nitra in 2009 and 2010. Four variants of fertilization, 2 ways of soil cultivation and four varieties 'Bojos’, 'Kangoo’, 'Marthe’ and 'Xanadu’ were observed. From the quality indicators the nitrogen content (%) was observed. The results were statistically analyzed by using a multifactor analysis of variance by using Statistica 8, the program Statgraphics. The difference between years was statistically significant (1.87 t ha-1) in favour of 2010. The difference was also significant between the varieties 'Bojos’ and ’Kangoo’(1.07 t ha-1), respectively. 'Martha’ and 'Xanadu’ as well as 'Kangoo’ (0.56 resp. 0.33 t ha-1). Conventional soil cultivation in
comparison with a minimalization technology, demonstrated a tatistically insignificant increase of yield. Significant differences were obtained between the variants of fertilization. Treatment by using Condit (b-var.) showed a very positive impact in climatic favorable year (2010) with a yield result of 7.42 t ha-1. In comparison with an untreated control, the difference in yield was 0.89 t ha-1. A significant increase of yield was achieved by using the combination of solid fertilizer with foliar fertilizer (LAV + Hakofyt, var.c) 0.47 t ha-1. The crude protein content was statistically influenced by a variety and year. In 2009, the crude protein content was above average (12.38%). Significantly lower attributes were achieved in 2010 (9.90%). From the studied/observed varieties the lowest crude protein content was showed by a variety 'Kangoo’ (1.68%). -
Regional Development Differences in Hungary and the Northern-Great Plain Region
62-71Views:510The most important endeavour of European Union’s regional policy is to moderate disparities. An emphasised strategic objective of member states, based on the principle of solidarity, fairness and justice, is to develop regions and almost forty percent of the common budget is devoted to achieving this objective.
Hungary, as a full EU member state, will get a new chance for underdeveloped regions, especially for the Eastern-Hungarian as well as the North Hungarian and North Plain Region.
The differences in development among the regions are significantly influenced by the economic characteristics of the specific region, quality and quantity of human resources, accessability of the region and other factors influencing local quality of life beside natural conditions.
The new spatial structure was formed by change of regime, processes of the nineties, primarily the economic renewal based on foreign capital investments and the crisis phenomena in parallel with these. The economic, political and social consequences of the transformation significantly changed spatial structure and increased disparities. New disparities formed which were further aggravated as a consequence due to the formation of the eastern-western slope and local crisis zones. As a result of the outstanding development of the capital, the long term differentiation of regional development differences can also be detected when examining the regional distribution of Hungarian gross domestic product. The collapse of heavy industry and agricultural mass production based on the eastern markets primarily affected the north-east counties in the eastern part of the country.
Strengthening regional competitiveness is of key importance for the region, which requires the application of consistent development policy. The most important is economic development which, if it operates well, also infers the possibility of establishing welfare infrastructures. Drawing in external sources to ease the significant lack of capital is important for the processing industry and the development of supplier networks. Agricultural development also plays an important role in transforming economic structure, since the characteristics of the region, its traditions and long term competitive advantages are favourable, therefore it is going to represent a higher ratio within the economy than the EU average. The modernisation of the agricultural sector can be promoted by supporting market accession, quality agricultural production and stimulating producer-retailer cooperation. The development of transportation and informatics infrastructure as well as human resource development plays a significantly important role in the development of the region.
In conclusion, the implementation of such a consistent regional development policy is required in the future, based on the strengths of the region, that serves the most efficient utilisation of regional development funds through the implementation of regional policy principles and prevents the irreversible decay of the region while promoting rapid development. -
Results of foliar treatments on Sugar beet (Beta vulgaris L.)
303-308Views:391The yield and quality of the sugar beet are mainly determined by the plant production system, thus we studied the effect of mineral fertilization. Our field trials were carried out in 2005 and 2006 in Hajdúböszörmény, at two sites. We studied the effect of sulphur (Cosavet DF), copper (Kelcare Cu) and two foliar nutrients with high active agents. Treatments were replicated four times.
We took root samples at 4 week intervals, starting in August. The quality of root (sucrose, potassium, sodium and alfa-amino N content) was determined from filtrated beet broth, by an automatic beet laboratory system, called VENEMA.
We found that the crop and the sugar yield were significantly influenced by the foliar treatments in both of the two years. -
Unfair commercial practices towards consumers in the Hungarian food industry
67-71Views:205Unfair commercial practices in the food industry can include actions and practices by traders or producers that mislead consumers about the true characteristics, quality, or price of products. For example, if a producer does not accurately and transparently list the composition of products, or if advertisements contain false or misleading information about products, or if inappropriate product quality is concealed, or if promised benefits of products are not realised, or if consumers are unfairly persuaded to purchase products.
It is important to note that all traders and producers must comply with consumer protection rules. If any unfair commercial practices are observed, consumers can legitimately file a complaint with the Consumer Protection Authority or the Hungarian Competition Authority.
Unfair commercial practices can be a serious problem for consumers as they mislead them about the true characteristics of products, making it difficult to make informed purchasing decisions. Therefore, it is important for consumers to be informed about the true composition and quality of products in order to avoid falling victim to unfair commercial practices.
Through various legal cases, I demonstrate how important it is for consumers to be fully informed and aware of their rights. Additionally, I illustrate how investigating different complaints can have an impact on preventing unfair commercial practices.

The parameters of homemade jams after storage
39-42Views:495Nowadays producing jams is considered a traditional way of plum processing in Hungary. Plum jams without added sugar can be stored
This research aimed to analytically determine which quality parameters of the jams and to what extent they change during storage. Furthermore, this study intended to find out whether a concious consumer can presume any difference between varieties or the year of harvest, or wheather a one-time customer should suspect differences in quality parameters of the different products. This study focused on those differences or alterations in the parameters that occur in the jams made from several different plum varieties produced in different years.
I analyzed the classic chemical parameters (dry matter content and ash content) and physiologically important nutritional components (phenolic and flavonoids antioxidants and vitamin C). In this research I used jams which were produced from 6 varieties grown in 2009 (President, Tophit, Bluefre, Elena, Presenta, Stanley), 4 varieties from 2010 (President, Bluefre, Elena, Presenta) and 6 varieties from 2011 (President, Tophit, Bluefre, Elena, Presenta, Stanley). Jams were produced with traditional technology in cauldrons without added sugar. Jars were placed into a relatively dark and cool place and were stored there until the analysis.
Having regard to the results, when consumers choose between the different products they also choose quality since the processed plum variety, and the year of production/processing determine the nutritional value of the specific product. This could be used for market positioning and promotion of the product, however further research is needed to gain more information from the differences that derive from the varieties, year of harvest or other factors. This way fruit and jam producers could turn these informations into market advantage.

Scientific background of precision animal nutrition
95-99Views:289Precision animal nutrition consists of meeting the nutrient requirements of animals as accurately as possible in the interest of a safe, high-quality and efficient production, besides ensuring the lowest possible load on the environment. This is facilitated by electronic feeding based on IT technology, an important but by far not the only tool of precision nutrition. In the present paper the following most important elements of precision nutrition are discussed: diet formulation, quality control of ingredients and compound feeds, reduction of the harmful effects of heat stress in pigs with different nutritional tools, application of the recent findings of the molecular genetics in animal nutrition, the relationship between genetics and animal nutrition and reduction of the N and P excretion by nutritional tools.

The effect of herbs on the microbiological stability and nutritional quality of pariser
101-104Views:256The purpose of this study was to evaluate the functional properties of dried herbs (Thymus vulgaris L., Origanum vulgare L., Salvia officinalis L.) to improve the quality characteristics and microbiological stability of Hungarian meat product, pariser. The addition of herbs did not affect the microbial properties of the product. According to the Decree No. 4 of 1998 of the Ministry of Health, pariser can be considered safe. The nutritional quality of the different forms of pariser was also acceptable. However, the addition of oregano, sage and thyme changed the flavor characteristics of the parisers and the higher meat content would increase the final price of the product.

Analysis of the Environmental Status of Nagykálló Subregion
362-367Views:200The third smallest region of Szabolcs-Szatmár-Bereg county is the Nagykálló subregion. Its territory is 377 km2 and its inhabitants number 32.526. Due to the fact that industrial development arrived late, the environmental status of this subregion was saved from serious ecological degradation. The quality of the environment shows a reasonable picture in many respects, comparing to the general survey of the country. The air quality of the region can be qualified as acceptable. Leaving some critical points out of consideration, it is better than the national average. It is favourable from the human environment point of view that the region is free of extremes, and has a balanced climate. The supply of drinking water is above 95%, and the remainsing water requirements are supplied by artesian wells. The water supply network is fully extended in the subregion. The most significant environmental noise source is traffic, including public road traffic, which causes a problem in the town of Nagykálló. The situation of the collection, transportation, and placement of the settlement’s solid wastes show a similar picture to the status of the country. The environmental status of the region is included in the SWOT analysis.

Sporting habits of students at the University of debrecen Centre for Agricultural Sciences
155-162Views:222In 2007, a new sport strategy was implemented, (XXI National Sportstrategy), which analyses the current conditions in recreational sports in Hungary and describes its developmental potentials. Additionally, last year a new concept for university sport was introduced (Hajos Alfred Program), having as its most important goal, to develop the recreational sporting activities within the universities’ environment. The latter is of high importance, as this is the last period, when, on an institutional level, we can establish and enhance the need for physical activity among young generations. In this study recreational sport is analysed in the University of Debrecen Faculty of Applied Economics and Rural Development. The purpose of the study was to analyse data on the sporting habits of the faculty students, their preference of where they like to exercise, within or outside of the university campus, and the reasons which can be found behind these preferences. Moreover, this study aimed to evaluate the service quality offered in university recreational sports. Data collection was completed on a paper based questionnaire, 42 closed-type questions were included and a total of 123 students completed it. Based on the results, college students usually complete their competitive level sport activity when they enter college and they continue this activity on a recreational level. Almost two third of them choose to exercise in places outside of the university campus. For those who choose university facilities for their recreational exercise, they do so because; it is usually cheaper and closer to access. In the service quality results we see, that females are less satisfied with teaching staff quality than males, it may be possible that females need more and more effective implementations in order for the universities to better satisfy their needs for physical activity.

Connection of crude protein content and amino acid content of forage and medium quality winter wheat varieties in the relation of quantity and quality
73-79Views:511We analysed the crude protein content, amino acid content, amino acid composition of four forage and milling III. quality winter wheat varieties (Magor, Hunor, Róna and Kondor) from their samples from five following years (2003, 2004, 2005, 2006, 2007). We found that quantity of essential and non-essential amino acids rose with increase in crude protein content. On examination of protein amino acid composition in relation to crude protein content we found that the crude protein content increased the quantities of the non-essential amino acids also rose, while those of the essential amino acids decreased as the lysine, the limiting amino acid of wheat. We also established that, as crude protein content increased, the biological value of the protein decreased.

Modern Food Safety and Product Identification
339-345Views:209In the beginning of the 21st century the matter of food safety plays an accentuated role in the food industry. Important issues in this topic are the risk of bioterrorism, impurities in the food chain and the ascendancy of customer needs. The solutions of these problems are the introduction of modern quality assurance systems, traceability and identification of products. I review in this paper the possibilities of these systems, the potential advantages and incidental costs. In the tight frame of this paper – omitting the descriptions of technologies – I discuss the most important criterions of systems, which may be able to solve today’s quality food industry problems.
