Trends in Dry Pea (Pisum sativum L.) Production
53-58Views:331Dry pea is an important, cool-season grain legume, which is grown worldwide on over 6 million hectares. The major producing countries outside Europe are China and Canada, followed by India, Australia, and the United States. France, Canada and Australia produce over 2 million hectares and are major exporters of peas. During the 1980’s, in developed countries of the European Union, pea production rose yearly by 6-10%, which represents a significant increase in both area and yield. Europe accounts for 50-75% of world pea production. In the 1990’s, the European Union produced 4-5 million tonnes of dry pea, of which 3-4 million tonnes were used for feed and 1 million tonnes for export. At the end of the 20th century, the growth in production was low, mainly because of the absence of support measures, and the better returns offered by other crops. In the countries of the former Soviet Union, dry pea was primarily used as feed and pea production dropped, due to a trend in livestock raising.
Food consumption of dry pea is concentrated in developing countries, where grain legumes represent a useful complement to cereal-based diets as a relatively inexpensive source of high quality protein. As a result, human consumption of grain legumes fell from 2,2 kg/capita in 1961 to 0,5 kg/capita in 1999. The importance of grain legumes in food protein supply decreased, while that of cereal products increased. Shortage of grain legumes has adverse effects on the nutritional standard of poor people in developing countries.
World dry pea production reached 16,7 million tonnes in 1990, with 3,7 million tonnes used as food, 11,4 million tonnes used as feed, and 1,0 million tonnes used as seed. Dry pea production was 10,9 million tonnes in 1999, and 3,5, 5,8 and 0,8 million tonnes was used as food, feed and seed, respectively. In the coming decades, world grain legume production and utilization as feed are expected to expand at a slower rate than in the 1980’s. Most of the increase is expected to occur in Eastern European countries, Canada and Australia, where production is anticipated to grow at 2% annually. The projection for the new millennium was derived from adjusted trends in area and yield over the period 1961-2000, based on FAO statistical data. -
Relationships of Fruit Production and Regional Development in the Northern Great Plain Region
181-187Views:264The role of retaining population in agriculture is stronger and more significant in the long run in the North Great Plain Region compared to other regions. The region has a significant processing industry along with a good basis for producing raw materials, developed food processing capicity and high quality agricultural products typical of the region. The GDP in agriculture, forestry and game management is somewhat higher than the national average.
Variety is of cardinal importance when establishing the quality of horticultural products and determining the product value. The Hungarian breeding results of apple, quince, apricot, cherry, raspberry, red and black currant are promising.
The regulation system of EU the vegetable and fruit market is based on Retail Cooperatives Producers. With the establishment of national vegetable- and fruit production and retail organizations, the market regulation, production and quality development issues of the sector can be handled and solved. Reaching EU standards in fruit production can only be achieved with up-to-date plantation systems and breed selection. A key issue in development is establishing the required financial resources for investments and updating production. In order to reach these standards, significant state subsidies and good credit conditions are needed. By solving these tasks, the sector is expected to become self-financed without government help.
The pursuit of safer production, improving quality and increasing yields require the establishment of up-to-date irrigation systems. The improvement of family farms, motivating land concentration is necessary for increasing average size of plants. Establishing the above mentioned conditions is important since the vegetable-fruit sector is of great significance in the employment of rurally based population, improving their living conditions and executing rural development programs. -
Implementation alterantives of the CIVAQUA complex water management program in the Debrecen region
71-73Views:308Hungary is one of the countries in Europe which has the largest amount of water supply because of its geographical conditions. Water comes from the surrounding mountains makes this water supply even more bigger. This precious water base needs to be treated responsibly and the most efficient way. The Civaqua program is a project with the above-mentioned conditions, made by the Local Government of Debrecen and the Water Directory of Trans-Tiszanian Region. This project deals with the exploitation of the East-Main Chanel’s water for social welfare, agricultural and inverimental protection purposes in Debrecen and its agglomeration. The aim of this paper is to give an overall insight into the investment plans of Civaqua program and it is also examines its positive direct and indirect effects on the region.

The management and economical aspects of GPS based machine-control and tractor-implement sincronisation
161-167Views:300Precision farming has an array of technological equipment, elements and complete systems which are in themselves suitable to create conditions for efficient farming, to reduce environmental load and to provide farmers with optimal return on their investment.
On the leading edge of my research is to introduce the economic benefits of precision logistic optimization with satellite navigation in wheat and maize harvesting. My hypothesis, claiming that a well-organized system can increase the number of working days by 4 days per harvesting season in maize, and 2 days in wheat crop. If the farmer makes contract works for harvesting it means for him 2 or 4 days extra work by using the precision farming technologies with satellite communication system. Overall, as pertains to wheat and maize harvest seasons, yearly revenues can be increased by 7 760 000 HUF. I would like to introduce that the precision technologies increase combine costs by merely 5.4% which can be return in the first year of using.

Different ideas on the pathogenesis and treatment of swine edema-disease
45-48Views:364Although literature data associate the reason of swine edema-disease with certain serotypes of Escherichia coli bacteria, the authors assume that the primary cause of edema is more different. Susceptible agents and factors, mostly of feed compound are involved. During the digestion of some feed-origin protein opiate-like metabolites, exorphins arise, simultaneously arrest the release of acetylcholine. Consequences of acetylcholine shortage are spasm of sphincters (mostly pylorus), intestine-dilatation, contraction of bladder-sphincter, and urine retention. The endorphins and exorphins intensify the insulin release from the pancreas, hypoglycemia evolves, which is associated with loss of balance. According to the authors in edema-disease piglet dies because of hypoglycemia.

The use of MFA indicators in the characterization of the settlement sustainability
107-116Views:171One of the key sustainability challenges for the coming decades will be to improve the management of natural resources in order to reduce current levels of anthropogenic environmental pressure and respect the biological and physical limits and the carrying capacity of the planet. The first step towards meeting this challenge is an enhancement of the understanding of the material basis of our society. In the past 15 years, scientists in several research institutes have created a fast growing field of research, a new family of different methods, named material flow analysis (MFA). These instruments have an increasing policy relevance: international organizations (UN, EU, OECD) have encouraged member states to establish MFA accounting in their statistical programmes and urged governments and economic actors to use these tools. In this paper I present selected examples to reveal how the MFA approach and derived material flow indicators can be used for the evaluation of sustainability policies at municipality level.

Phytoplankton diversity and their relationship with water quality parameters in the middle basin of Ogun River, Abeokuta, Southwest Nigeria
5-13Views:222Phytoplankton are crucial bioindicators for assessing freshwater ecosystem health. This study investigates the diversity and distribution of phytoplankton and key water quality parameters in the Ogun River. Monthly samples were collected from three sites along the river between February and August 2024. Phytoplankton samples were preserved with 4% formalin and analyzed microscopically, while water quality parameters, including temperature, pH, dissolved oxygen, conductivity, transparency, total dissolved solids, nitrate, phosphate, alkalinity, and hardness, were measured using standard methods. Results showed temperature ranged from 27.3–31.9 °C, pH from 6.7–9.4, dissolved oxygen from 4.3–7.2 mgL-1, conductivity from 10.8–20.9 µS/cm, transparency from 0.27–1 m, and other parameters within specified ranges. Sixteen phytoplankton species from 10 families were identified, with the Bacillariophyceae family being the most dominant, representing 7 species. Lyngbya spp. was the most abundant species, followed by Pediastrum simplex. Species richness was 12 species at Site A, 13 at Site B, and 14 at Site C. Dominance values were 0.13, 0.11, and 0.12, respectively. Simpson’s diversity index ranged from 0.87 to 0.89, and the Shannon-Weiner index was 2.24 at Site A, 2.38 at Site B, and 2.35 at Site C. One-way ANOVA tests showed no statistically significant differences in diversity indices among the three sampling sites (p > 0.05), indicating relatively consistent phytoplankton diversity across the study area. These findings highlight the importance of integrated biological and physicochemical monitoring for effective water management and ecosystem conservation in the Ogun River.

Effect of noninvasive castration method on weight gain, behavior and meat quality of ram lambs
21-29Views:392In the course of producing heavyweight lambs (above 35 kg), males need to be separated from females at the end of the fattening period. If not, the rams must be castrated because they reach sexual maturity, and their activity bothers the ewes or unwanted pregnancy may occur. The present study surveys if the Hungarian sheep keepers know or use the non-surgical elastrator method for castration and assess the effect of castration (surgical and non-surgical) on daily weight gain, behavior, moving activity, and meat quality of rams, respectively. We found many advantages regarding the use of the elastrator method. Based on the survey results, 100% of farmers who used elastrator had a positive experience and favorable opinion about this method. There is no need to separate the rams, which allows for less area requirement and more economical technological conditions. The traditional castration (with a knife) process is longer (4–6 minutes), and caused longer-lasting stress while the elastrator application is bloodless, took only 20–30 seconds, and were stress-free. The number of steps of ring-gelded individuals was much lower than that of the non-castrated rams. The difference in steps number could also be seen in ewes separated into different ram groups. The weight gains of individuals castrated by the ring were better than the surgically castrated ones and also individuals with testicles. The palatability of the meat from the non-castrated group was less favorable, and the chewiness of the ringed group was the best. Finally, our results highlighted the benefits of the noninvasive elastrator method in animal welfare aspects.

Study of changes in the strength of connection between grey cattle cows and their offspring after weaning
129-136Views:653It is important to minimize stress for cattle because of animal welfare and profitability. This study aims to reveal how long after abrupt weaning the cow and her offspring show a need to rebuild the connection if physical barriers are removed and distances disappear. The research was carried out on Szamárhát Farm owned by the Tiszatáj Foundation, Hungary. In the autumn of 2019, thirty-one calves were weaned, randomly selected from 81 grey cattle cows’ offspring. The oldest calf was 10 months old, while the youngest one was 6 months old on the day of weaning. They were divided into three groups and reunited with the cows during the first, third, and fifth weeks after weaning. Each reunion happened in the early afternoon and the cow and her offspring spent 24 hours together again. The formation and the strength of the connection were recorded for an hour three times during this period, first in the afternoon, then in the morning, and the next afternoon. It can be seen that both parties showed the need to form the connection during the first week after weaning because the bond made between them was obvious in a short time. The connections proved to be strong. However, neither the cows nor their offsprings showed any intention to form strong connections in the third and fifth weeks. In the majority of the cases, no connection was formed.

Development of the antioxidant indexes (FRAP, TFC, TPC) of scabbing resistant apple varieties in storage
89-94Views:275One of the most important groups of bioactive substances in apples are antioxidants, which have a health-preserving effect. The amount of these compounds varies not only during the ripening of the apple fruit, but also continuously during post-harvest storage. A growing group of health-conscious consumers are looking for apple varieties with a nutritional value that satisfies their needs.
In the scope of our research, we examined 5 apple varieties originating from the Derecske horticultural site of KITE cPlc. in 2016. The plantation was planted to be suitable for intensive apple production. Samples were collected at the time of maturity (August-October) of the given variety. The 5 examined apple varieties (Gaia, Isaaq, Modí, Smeralda and Fujion) are all resistant to apple scab (fungal disease caused by Venturia inaequalis). The 2-month storage experiment was conducted at 16–17 °C, which had an aggressive effect on our stored apples. Total polyphenol (TPC) and flavonoid (TFC) content as well as FRAP values of the apples were measured. Measurements were taken immediately after harvest and after 1 and 2 months of storage. Our results were evaluated by using the IBM SPSS Statistics 20 software. Our aim was to compare the antioxidant results of 5 scab-resistant apple varieties, which change continuously during storage.
The antioxidant content of our apple varieties increased during 2 months storage. The best result was achieved by the Modí apple variety (FRAP: 467.32 mg/100g; TFC: 317.76 mg/100g; TPC: 1771.97 mg/100g). Consumers may want to consume apples stored for a longer period of time if they are to absorb large amounts of antioxidants.

Study of Educational Motivation among Agricultural Managers
161-170Views:223It is a priority for companies to utilise human resources as much as possible. The form and effectiveness of the utilisation of labour largely depends on how much the manager of the company and the human resource management area support and encourage labour to develop individually and work more efficiently – as far as the size of the company justifies and allows. Effective incentive methods have to be set and run. Training incentives will have to play an important part in the future.
There has been no major difference between training incentives between managers and subordinates. Material incentives continue to be the key factor. For managers, exchange of information is currently a primary training incentive, as is the opportunity to meet other experts and exchange their ideas. Further, performance-related payment and bonuses applied jointly are also some material incentives. In the future, material incentives will gain in importance. For subordinates, the operation of material incentives is currently highly important as a training incentive. This is not expected to change in the future either, while expectations linked to quality work will strengthen. -
The Valuation System of the National Land Fund
317-323Views:215The aim of establishing a National Land Fund was to realise the rational management of land property belonging to the Hungarian State, to assist in the realisation of estate political directives, and also to support the development of a modern property structure based on family farms. During this 3 years operation the National Land Fund has become the major player of the Hungarian land market. It has arranged land trades totaling 15,000 hectares, which makes 50% of total related turnover. The NLF created the reason for the existence of land as credit security with the provision of security of mortgage credits. National Land Fund has written co-operation contracts with 11 commercial banks in order to provide long-term agricultural mortgage with the background of land security. NLF has issued almost 1,000 conditional declarations of land purchase to the banks, helping the credit system of agricultural companies.
The valuation system „TÉR” created by the National Land Fund, is a many-sided, flexible system adjusted to Hungarian conditions. This evaluation system can determine the value of land in a reliable way. NLF built further controls into the process with the co-operation of independent revisers providing real determination of land value. -
Cytochrome b diversity of Hungarian Botrytis cinerea strains
18-21Views:284In the mitochondrion of eukaryotes, cytochrome b is a component of respiratory chain complex III. Cytochrome b is encoded by the
cytochrome b (CYTB) gene located in the mitochondrial genome. The fungicidal activity of QoIs relies on their ability to inhibit mitochondrial respiration by binding at the so-called Qo site (the outer quinol-oxidation site) of the complex III. Since their introduction, QoIs (like azoxystrobin) have become essential components of plant disease control programs because of their wide-ranging efficacy against many agriculturally important fungal diseases like grey mould on various crops. QoI resistance primarily arises from a target-site-based mechanism involving mutations in the mitochondrial CYTB. As the management of grey mould is often dependent on chemicals, the rational design of control programs requires the information about the diversity of genes connected with resistance in field populations of the pathogen.
Monospore B. cinerea field isolates has been collected during 2008-2009 from different hosts in Hungary. PCR fragment length analysis
indicated the high frequency presence of type large intron in the isolates while in a few strains G143A substitution could also be detected.
These results indicated the heterogeneity of CYTB in the Hungarian B. cinerea populations, which possibly involve the heteroplasmy of this
mitochondrial gene, moreover indicates the existence op azoxystrobin resistant populations in Hungary.

The role of network administrative organizations in the development of social capital in inter-organizational food networks
11-20Views:231This paper is concerned with the role of network administrative organizations (NAOs) in the development of social capital in interorganizational
networks aiming at supporting their members to innovate in the food sector through interacting with one another. A multi-case study approach is used whereby three Belgian interorganizational networks are investigated i.e. Wagralim, Réseau-Club and Flanders Food.
Our study shows that there are many options available to NAOs to build social capital within the networks they are responsible for. We propose to categorize these options in three main distinct groups. First, NAOs may nurture the development of social capital within the network through creating ‘space’ boundary objects which appear, in our study, to be an absolute precondition for the development of interactions and hence creation of ties between network members. Second, NAOs may impact the development of social capital by favoring certain members – or set of members – over others due to their characteristics such as good reputation, possession of common past experiences, multidisciplinary experiences, non-conflicting goals, similarity in terms of sector of activity and/or experience level and common mindset towards information exchange. Third and finally, NAOs may foster social capital development by enhancing effective communication between members on the one hand, and between members and the NAOs’ coordination and decision bodies on the other hand, via a clear mandate, network decision making
bodies composed of members, the use of ex-post evaluations and formal governance mechanisms (e.g. legal contracts), and the selection of staff endowed with a proactive and perspective taking behavior and able to show neutrality when conflict arise. -
The R&D and innovation activity of agribusiness enterprises in Hajdú-Bihar County
67-71Views:219Economic changes have significantly accelarated in the 21th century. In this turbulent market environment enterprises are forced to adapt continously as they must be flexible in order to meet changing market needs. To achieve flexibility companies require innovation. The economic relevance of innovations is significant in every market sector and agriculture is no exception. Re-dynamizing agricultural innovations is a possibility for the outburst of the Hungarian agriculture. Agricultural enterprises have to face competitors as well and they should give priority to efficiency, sustainability and competitiveness in order to preserve their position in BOTH global and domestic markets. This study examines the innovation potential of the agricultural enterprises in the North Great Plain region based on own databases and case studies.

Examination of the effects of the cropyear and the nutrient supply on the quality of winter wheat with the help of Győri’s Z-index
121-125Views:166In the case of winter wheat,the knowledge of several quality features is needed to be able to determine precisely the real quality of the given
wheat. Several systems have been worked out on the qualification of the winter wheat in Hungary and other countries as well. Evaluating the
quality is being made more difficult because the different quality features take part in the development of the quality in different degrees and
the values of the several quality features are in different intervals and these data are different dimension values. On the evidence of the
results, in the case of considering several features,it can be difficult to rank into one concrete quality cathegory. Researchers are trying to
develop complex quality index numbers in order to be able to define the quality more precisely. One of these complex quality index numbers
is Gyıri’s, so called, Z-index.
In three years from 2006 and 2008, we examined the change of the quality features of nine varieties of winter wheat with the help of the
Z-index under the influence of the effects of the different cropyears and the fertilizer treatment. The results show that the Z-index of the
examined varieties of winter wheat were influenced by several factors. Examining the data of the three different breeding years together we
can observe the corrective effect of the different cropyears on the Z-index, and if we examine the three years separately and together, the
differences of the quality features of the different varieties differentiate very well, and with the help of the Z-index the comparison of the
types is easier and perspicuous, and the Z-index represents the different nutrient reactions of the different types as well. On the average of
the three years, the types gave the best results at N120-150+PK nutrient level. Among the nine varieties the best results were given by Mv Suba,
GK Békés and Mv Mazurka in the case of both low and higher nutrient levels. -
Biomass production estimation of processing tomato using AquaCrop under different irrigation treatments
131-136Views:502The wiser usage of irrigation water is inevitable in the future. Irrigation has very high input cost; therefore, farmers must carry out irrigation with care. Also, the effect of irrigation on crops has a big role in decision making. Modeling provides a possibility to evaluate this effect. AquaCrop, as a crop production simulation model has great potential in this field. The accuracy of tomato biomass yield prediction of the model was tested in this research. For collecting the necessary data, a field experiment was conducted at Szarvas on processing tomato with different water supplies, such as 100% (I100), 75% (I75), 50% (I50) of potential evapotranspiration and a control with basic water supply (C). The relation of the simulation and actual biomass yields was evaluated during the season. Very good correlation was found between the modelled and the actually harvested data. The data for the control and I100 treatments showed higher correlation than the I75 and I50. The relationship for all of the data was moderately strong. Miscalculations occur mostly when the dry biomass yield reaches
7 t ha-1. The accuracy of the model was evaluated with the use of mean absolute error (MAE) and root mean squared error (RMSE) values. The least error was found in the C treatment, which means 0.34 MAE and 0.45 t ha-1 RMSE. The simulation resulted in higher errors in the I75 and I50 treatments. -
Occurrence of woolly cupgrass (Eriochloa villosa /Thunb./ Kunth) in Hajdú-Bihar county, Hungary
119-123Views:188Woolly cupgrass (Eriochloa villosa /Thunb./ Kunth) is native to East Asia, it spreads in several parts of the World and causes difficulties in plant protection, especially in maize. Difficulties in control of Eriochloa villosa originated from several reasons: seeds continue to germinate later in the season, significant part of seeds emerges from a deep layer of the soil, and the species is less susceptible to some herbicides applied to maize than other annual grass weeds.
The first report on the occurrence of woolly cupgrass in Hungary was published in 2008, and it reported about the appearance of this species near to Gesztely village (Borsod-Abaúj-Zemplén county), however, no information has been added about spread of the weed in Hungary until now.
A significant population was discovered next to Debrecen (Hajdú-Bihar county) in summer, 2011, and then weed associations were examined in maize, sunflower and stubble-fields on several km2 in the area to estimate the Eriochloa villosa infection. The weed species was found on every maize field bordering with a ground cover of 0.5-4%. Woolly cupgrass occurred inside of the 50% of maize fields, and reached a ground cover of 76% in case of most infected area, in addition it was found in sunflower and stubble-fields.
The spread of woolly cupgrass is expected in this area, which requires the consideration of this species in the planning of weed management technologies. -
Seasonal changes of photosynthetical parameters as a results of forest gap model
133-136Views:412Photosynthetic parameters of English oak (Quercus robur L.) as a member of Querco robori-Carpinetum were investigated in two different habitat in terms of gap forest management: in the gap and in the host forest. The artifical opening process of the forest resulted in more light for growing saplings and need for acclimatization. Photosynthesis is one of the most important way for plant life and plant production. In the centre of photosynthetic efficiency the quality and quantity traits of photosynthetic pigments are standing. During our work some photosynthetic parameters of plants (in the gap and in the forest as well) were measured: relative chlorophyll content as SPAD index, chlorophyll a and b content, total chlorophyll content and ratio of chlorophyll a and b. Based on our results no significant differences among our data in early spring. Although, during the summer significant differences occurred between the measured values in the gap and in the forest area. Lower total chlorophyll content was experienced in the gap, than in the forest area due to the lower chlorophyll-b content. Because of the high light intensity higher chla/chlb ratio was measured in the gap. The lower chlorophyll contents of gap habitat may have a part of the acclimatization process of photosynthetic apparatus against high light stress, which can determinate the survival chance of individual.

The importance of millet production in regional production, with special emphasis on climate change
141-146Views:415Regional production is a traditional production structure developed adjusting to the geographical, climatic, biological and soil conditions in given production regions, a certain territorial specification of agricultural production, and a type of farming that best fits the natural conditions and takes the biological needs of plant and animal species into account as fully as possible. The most probable element of risk in plant production is the changeable, extreme weather. That is the reason why the specific characteristics of the place of production and the characteristics of regional production should be considered to a greater extent. The establishment of the range of varieties appropriate for the place of production is the key issue in regional production. One of our historically grown cereal plants that perfectly fits regional production is millet. Due to its short growing season, favourable reproduction ratio and the fact that it is relatively undemanding, it used to be grown in larger quantities in the middle ages. Its good nutritional values made it an important food item, but over time, as a result of industrialisation and technological progress; it has been eclipsed by other cereal crops. In our country it is mainly used to cook porridge, but it is also used in the form of flour and as a base material in the spirit drinks sector. In the recent decades, millet has been applied only in a small area, mostly as a secondary crop in areas that dried out from drainage water in late spring, or as a replacement of extinct sowings due to its late sowing time. Water will be the most significant factor for the future of agriculture, especially considering climate change.My examinations took place in the area of the Institutes for Agricultural Research and Educational Farm of University of Debrecen, in the Research Institute of Nyíregyháza, in a small-plot experiment with four replications in 2016. -
The effect of grazing of various cattle breeds on botanical composition of low-lying pasture in Hortobágy
57-63Views:677Coenological surveys were conducted in the Hortobágy National Park (Pap-ere and Zám-puszta) in May 2015 and 2016. During the tests,a total of 40 permanent plots were analyzed on grasslands grazed by extensive cattle (Hungarian Grey) and mixed genotype intensive cattle. The presence of plant species, percentages of total coverage of species and vegetation cover were recorded. Two habitat types were chosen according to their moisture content: wet salt marsh meadow (Bolboschoenetum maritimi) and drier salt meadows (Beckmannion eruciformis).
We compared the impact of increased number of animals (2016 years) and the low number of animals (2015 years, initial state) and the grazing exclusion on vegetations.
We tested: (i) what is the impact of grazing on the vegetation, (ii) how do species composition and vegetation charachteristics differ in the two habitat types (iii) and is there a difference in the impact of different cattle breeds (Hungarian gray, intensive beef cattle) grazing on the grasslands species composition? During the investigation we found, (i) that the greatest number of species was recorded in 2015, on the area that received moderate to intensive grazing (14.3 species per m2). Somewhat the number of species was reduced in 2016 due to more intensive grazing. The control group had the lowest number of species (11.7 species per m2). The undergrass and legumes cover significantly increased on intensive grazed lands. (ii) Our results indicate that the effects of different grazing differ in the two studied habitat types. On the drier grasslands greater number of species were found (16.2 species per m2), oppositely to the wet grassland (11.2 species per m2). The cover of the undergrasses was higher in the drier habitat than in the wet. (iii) The extensive beef cattle left a bigger number of species (16 species per m2) than the intensive beef cattle (11.4 species per m2). The grass cover was more intense on areas grazed by intensive cattle. The absolute and potential weeds cover showed a higher value on areas grazed by Hungarian Grey. Our two-year results suggest that grazing by both extensive and intensive cattle breeds can be a proper tool for the conservation management of alkali grasslands. -
Evaluation of the use of leaf fertilizers and growth regulators in winter wheat: A review
77-82Views:374Winter 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.

Evaluation of bioactive substances in different parts of the root in beetroot (Beta vulgaris ssp. esculenta var. rubra)
33-38Views:351Beetroot, also known as Beta vulgaris ssp. esculenta var. rubra, is a root vegetable that contains a substantial quantity of bioactive elements, notably antioxidants and anti-inflammatory properties. These bioactive compounds, including betalains, phenolics, and flavonoids, contribute to the health-promoting properties of beetroot. The antioxidant and anti-inflammatory effects of beetroot have been extensively studied in preclinical and clinical settings. The active compounds in beetroot have been reported to provide benefits in reducing the risk of various diseases, our research provides a comprehensive analysis of the bioactive compounds the inner and outer skin parts of the root structure. The findings aim to contribute to a deeper understanding of the potential health benefits associated with specific beetroot root components. Furthermore, the results have implications for optimising beetroot cultivation and processing for enhanced nutritional value. This research not only advances our knowledge of the phytochemical profile of beetroot outer skin but also offers valuable insights into the broader field of plant biochemistry and its applications in promoting human health and nutrition.

The effect of Willow extract, Bistep and their combination on some quality parameters of lettuce (Lactuca sativa L.)
239-247Views:376The research described in this paper was conducted at the University of Debrecen, Farm and Regional Research Institute in its Botanical and Exhibition Garden, Hungary. The aim was to investigate the influence of plant biostimulants on the morphological parameters of three lettuce varieties (May King, Kobak and Great Lakes). Willow bark extract and Bistep were used through irrigation and spray onto the plant leaves with the amount of 5% Willow and 0,5% Bistep. Vegetative parameters like head structure (1….10), head weight (g head-1), head closing (1….10), number of leaves, head diameter (cm), internal stem size (cm) and root weight (g head-1) were measured in 2019 and 2020. According to our results, vegetative parameters are significantly affected by plant varieties and treatments. In the experiment of 2019, important vegetative parameters were influenced by the Willow extract, while in the season of 2020 the most influenced parameters were under the impact of Bistep biostimulants followed by Willow+Bistep. However, the most favourable vegetative growth was recorded in the Kobak variety in the season of 2019 followed by May King and Great Lakes varieties in the season of 2020. On the other hand, the interaction effect of plant varieties and plant biostimulants on the vegetative parameters were varied from seasons. For example, for the season 2019, significantly the highest vegetative value was recorded for the interaction of May King variety treated with Willow extract, whereas in 2020, significantly the most influenced vegetative parameters were under the influence of the interaction of Bistep and May King variety followed by the interaction of Willow+Bistep and Kobak variety.

Financial interrelationships of public warehousing
80-89Views:196In my paper I examined the institutional and market connections warehouses use emphasising the role of financial institutions. I stressed that for the proper functioning of a warehouse the mutual trust of the economic participants is required. This presupposes a tight relationship between warehouses and banks, as banks have to accept warehouse warrants in such a manner that the credit suppliant can more readily access current assets credit.
Today, we can say that the moneylender bank is strongly confident about deals involving warehouse credit. The amount of goods stored in warehouses is increasing. Warehouse deals offer better conditions to depositors, which can be explained by the fact that the creditor does not examine the management and credit standing of the depositor. Most important for them is that the goods provide enough collateral to ensure marketability, and that the warehouse storage conditions are proper. On the other hand, with the support of an interest subsidy system credit is obtainable at very auspicious conditions. To top it all off, and this is the most important aspect participants can receive access to funds unavailable to them in any other case.
