Stinging nettle (Urtica dioica Linnaeus) (Urticaceae) is a well known medicinal plant cultivated in some European countries for a long time. Because of its multiple usability (food, medicinal plant, feed, fiber), adventageous agrotechnical qualities and low demands for plant protection, its more extensiv utilization can be expected. However, du...ring cultivation from time to time little damages can be occurred on it. The aim of this paper is to show and estimate the most important arthropods (pests and natural enemies) of stinging nettle. Under the pests characterized in the paper according to the references the peacock and the small tortoiseshell are the most important species living on stinging nettle. Their individuals from time to time propagated can cause an important damage on nettle leaves in cultivated nettle stands or assemblages. On the base of a 12 year observation period (Gödöllő, Debrecen, 1998-2010) the following species have been observed: Psylliodes attenuata, Chrysomela fastuosa, Phyllobius pomaceus, Pleuroptya ruralis, Inachis io, Aglais urticae, Microlophium evansi, Microlophium carnosum, Aphis urticata, Dasineura urticata, Tritomegas sexmaculatus. Inachis io has been the only species which during the observation period did danger the stinging nettle stand. The other pest species have not threated even timely either the stinging nettle stand or a single plant. The number and diversity of natural enemies was rather low: running crab spiders (Philodromidae), tangle-web spiders (Theridiidae), crabbing spiders (Thomisidae), lacewings (Chrysopa perla, Chrysopa formosa), coccinellids (Coccinella septempunctata, Propylea quattuordecimpunctata, Adonia variegata), hoverflies (Episyrphus balteatus), earwigs (Forficula auricularia), scorpionflies (common scorpionfly (Panorpa communis) and European paper wasp (Polistes dominula) predominated.
Apiarists let prepare by bee honey products containing medicinal drugs. Our aim was to prove that the active ingredients originated from the herbs are also present in the bee products. This publication focuses only to the chamomile (Matricaria chamomilla) containing feeding syrup and the difference between the various syrup phases. To fulfil th...is task, we developed a method analysing the non-volatile components of the syrup using the flowers of chamomile. The method involves a filtration followed by HPLC-MS analysis. The analyses and the data evaluations proved that the non-volatile components of the herb were transferred to syrup. As the characteristic components of certain herbs could be identified also in the syrup, it is obvious that the components responsible for the medicinal effects are also transferred.
In Hungary the dairy sector is in a long-term critical period, the stock has been in constant decline. The consumption of milk and dairy products in Hungary is slightly rising compared to the world tendency, and it is fallen behind the level in 1990. The milk consumption per capita in 2006 was with 75 liters less than the EU-15 average. Dairy e...nterprise is a very risky activity: the profitability of the enterprise is affected by the fluctuation of feed and animal health products prices from the side of inputs, and by the fluctuation of end-product prices. Under these circumstances it is vital for the
cattle breeders, in order to survive, to harness the reserves in the breeding as effectively as possible. In our research we made a multi-faceted efficiency analysis of an agricultural holding’s three dairy farms. The chosen method for the analysis was Data Envelopment Analysis (DEA). The
selection of the method is justified by the fact that there is not such a reliable database by which we could define production functions, and that DEA makes possible to manage several inputs and outputs, i.e. multiple decision problems, simultaneously. By using DEA the sources that causes shortfalls can be identified, analyzed and quantified on farms that does not operate efficiently, thus it can help the corporate decision support successfully. In the model inputs are the cost data per one liter milk – feed, medicinal product use, logistic costs -, and the main parameters
concerning the keeping and rearing. Outputs are indicators concerning milk production, milk quality and others. We prepared the model in MS Excel, the linear programming model series were programmed by Visual Basic. After solving the model, in light of the shadow prices we can determine why either of the farms is not efficient.
Nowadays in Hungary nearly 5 million hectares of agricultural area was infected with ragweed (Ambrosia artemisiifolia). According to the public opinion the ragweed is a weed. From agricultural and public health point of view it is exceptionally dangerous plant. As it contains a number of useful active ingredients, based on this the ragwee...d is consider a medicinal plant. Our goal was to present that the ragweed contains antifungal active substances as well. In the experiments we used the pre-flowering plants with roots and we extracted the biological active components of dried plant. We tested the biological activity of the extracts against Monilinia laxa in vitro. We related based on our examination that ragweed contains biologically active agents, by which it is hampered the reproduction of the Monilinia laxa.
In this research, the purple coneflower’s (Echinacea purpurea L.) nutrient requirement was examined under different fertilization conditions in a small plot experiment. We measured the medicinal plant’s raw and dry herb and root drug mass and drying loss under different fertilization settings and meteorological factors.
From the dru...g’s raw and dry mass perspective, based on the results, in our opinion, the control setting exceeded all nutrient settings’ results in 2016. In 2017 and 2018, the N75P100K150 nutrient setting has the biggest herb yield. As for the root yield, it was also the N75P100K150 setting which produced the biggest yield.
The Pearson's correlation test was performed to investigate the connection between the quantity of the raw, the dried herbs, the different nutrient settings and meteorological factors.
Cucurbita pepo var. styriaca is known as a medicinal crop among other cucurbits. The benefits of cucurbits fruits are very important in terms of human health, purification of blood, removal of constipation, digestion and supplying energy. The mutant styrian oil-pumpkin (Cucurbita pepo L. convar. Pepo var. styriaca Greb.) exposes a complete lack... of lignification of the seed testa. For this reason, this kind of naked pumpkin seed is more consumable as snack than other seeds. The vegetative growth of plants is crucial for fruit production. Nitrogen is the most imperative element for the proper vegetative growth and development of plants which significantly increases and enhances yield and its quality by playing a vital role in the biochemical and physiological functions of plants.
Field studies were conducted to study the effect of nitrogen nutrition on certain physiological parameters and their differences between the styrian oil pumpkin hybrid and cultivar (Gleisdorfi Classic cultivar and GL Rustical hybrid). The small block experiment was carried out based on a factorial experiment with a completely randomised block design and four replications in the Research Institute of Nyíregyháza during the summer period of 2017 and 2018. Three different concentrations of nitrogen fertiliser was applied at sowing. Photosynthetic pigments (chlorophyll-a, -b and carotenoids) were analysed as one of the basic factor of efficient photosynthesis. The yields of two genotypes were also measured in all treatments as seed-weight. The contents of photosynthetic pigments were higher in the oil-pumpkin hybrid, mainly the carotenoids in 2018. The vegetation period of 2018 was drier than in 2017, the hybrid oil-pupmkin was more efficient in stress tolerance than the cultivar with higher carotenoids pool. The obtained yield was more pronounced in the oil-pumpkin hybrid than the cultivar in all examined years. The hybrid GL Rustical was more sensitive to nitrogen treatment than the cultivar Gleisdorfi Classic.

My study examined the competitiveness of Balmazujvaros, in regard to tourism. The town is situated in the Northern Great Plain region, in Hajdu-Bihar county, 22 km from Debrecen, together with Egyek, Hortobagy and Tiszacsege joined the statistical subregion of Balmazujvaros. Comparing with the neighbouring settlements, it has similar geographic...al features and posesses thermal water that was determined to be medicinal, which is a feature of the region. Balmazujvaros as a typical country town as it has a dominant agricultural character. It gained town status in 1989. Part of the town is situated in the National Park of Hortobagy.
The first part of my study is to determine the number of rival settlements from the viewpoint of tourism. I will analyze the results of a questionnaire given to tourists in Balmazujvaros between June 15 August 31 2003, and introduce the primary results. The SWOT analysis will show the primary and secondary information and the examination of the results.
If we take into account the strengths, weaknesses, opportunities and threats of this town, we can make the following conclusion: tourism is an opportunity with a well-developed infrastructure, a third sector, subsidies and improved local interest. A sound and well-defined marketing strategy is essential for Balmazujvaros, in order to overwhelm its strong rivals
The effect of two Chinese herbs (Ganoderma lucidum and Lonicera japonica) on non-specific immune response of tilapia was examined. In addition to the control (no herbs), three diet variations were used. These contained 1.0% of Lonicera, 1.0% of Ganoderma and a mixture of Ganoderma (0.5%) and Lonicera (0.5%). The respiratory burst and phagocytic... activity of blood leukocytes were monitored. Three weeks after feeding, the fish were infected with Aeromonas hydrophila. The results of this study showed that feeding tilapia with Ganoderma and Lonicera alone or in combination enhanced the phagocytosis of blood leukocytes, but not the respiratory burst activity. Both herbs, when used alone or in combination, reduced mortality after challenge with A. hydrophila. The highest mortality was observed in the control fish – 56.66%, and fish fed with Lonicera extract – 43.33% while 30% of fish died in the group fed with Ganoderma and the lowest mortality (20%) was observed when the fish were fed with a combination of the two herbs. It can be concluded that the herb extracts added to this diet act as immuno-stimulants and appear to improve the immune response and disease resistance of tilapia.
