Alternatives of the multiple use of Virginia mallow (Sida hermaphrodita L. Rusby) as a shrub-replacing mallow in the temperate climate zone
51-56Views:158In the seventies of the previous century, Dr. Zoltán Kováts set two directions in the research of mallows. One of the directions was the biotechnology of the mallow species and the other direction is using the mallow species as biomass material. In order to do this he brought mallow mother spawns of ornamental and biomass sorts from botanical gardens abroad and tested many of them, including the a Sida hermaphrodita kind. Fourty years later, for the second time this plant, known as the „energy mallow” got back to Hungary again, right into the sight of hungarian biomass business with the help of László Balogh and his associates using help from Poland. This genus got into the center of our research, because of it’s valuable attributes. The latest experiments are about using it as an energy plant, without examining genetic details. The plant grows up to more
than 3 meters, has high growing rate and produces big amount of green mass. We don’t have any hungarian data about whether the plant continues the sufficient growing rate or not, after cutting it back.
We have to explore the potentials in the Sida’s sublimation. The plant is mostly suitable for ornamental and energy utilization, so further sublimation should be aiming for these aspects. During my research period, we are willing to get to know these potentials and the best possible use of them. -
Possibilities of Growing Artichoke (Cynara scolymus L.) in Hungary
126-130Views:86The domestication of choice broadening, special vegetable species offers new market possibilities in Hungary. The production of artichokes has good perspectives due to its high protein, vitamin and mineral contents and its wide usability. According to the literature, in Hungary it is worth examining the annual production technology, which has yet to be researched in our country. The basic aim of our work was to establish the annual production of artichoke in Hungary with scientific research.
In the experiment, 5 Italian sorts (Valetta di Roma, Gobbo di Nizza, Violetto di Romagna, Violetto S. Francesino and Precoce di Romagna), 1 American sort (Green Globe) and 1 Egyptian sort (Balady) were used. For one half of the plants, we tried to bring on bud-production appearing in the first year only with early planting, while we used also a gibberellic acid hormone treatment for the other half.
Only the sort Green Globe had yields in appropriate quantity (21.4 t/ha) and quality. The low yield and inequable quality of buds of the Italian and Egyptian sorts refers to the fact that these sorts are not applicable for annual production in Hungary. Although the gibberellic acid treatment resulted an earlier harvest, increased the equality of buds and increased the proportion of stems producing buds except for the sort Green Globe, overall it did not have a positive effect. The hormone treatment fastened the physiological processes of the plants, thereby it induced early insenescence and lignifying of the buds. The high temperatures during the bud-formation period largely increased the ratio of flabby, over-blowing buds, so the planting must be timed in the future that the harvest period is in early automn or late spring, early summer months.
According to our results, globe artichoke can become a perspective culture by applying cold-resistant sorts with short growing seasons, which can be produced as annual crops without hormone treatment by the appropriate timing of bud-formation. -
Harvesting system established for the utilisation of Miscanthus sinensis ‘tatai’ “energy cane” in biomass power plants
143-150Views:139The increasing demand for energy worldwide and the resulting environmental impacts of fossil fuels forced many countries to turn to renewable energy resources as a clean and sustainable alternative. More than a third of Europe’s binding renewable energy source target of 20% by 2020 will come from solid biomass for electricity and heating according to the National Renewable Energy Action Plans submitted by member states of the European Union (EU) to the European Commission. To achieve this goal long-term yield studies in renewable energy plants are important to determine mean annual biomass and energy yield, and CO2 emission. Field experiments worldwide and also in Europe have demonstrated that Miscanthus, a fast-growing C4 rhizomatous grass can produce some of the highest biomass and energy yield per hectare of all potential energy plants. Miscanthus is a plant that originates from the southern slopes of the Himalayas. It was bred for the Hungarian climatic conditions in 2006 under the name of Miscanthus sinensis ‘Tatai’ (MsT). The species has high frost and drought tolerance and high energy value. This is why there is growing demand for the biomass (lignocellulose) produced by growing this plant. The biomass, produced from the high yield energy reed, can be transported to power plants in large quantities, in forms of bales. Its household consumption is not yet significant. This study presents the external features, characteristics, propagation and plantation process of MsT energy reed. The study also demonstrates the harvest technology of the species worked out between 2009–2012 in Tata, Hungary and the options of supplying to biomass
power stations.

Fungi detected in trunk of stone fruits in the Czech Republic
121-127Views:206This study was focused on detection of the spectrum of fungi in the wood of stone fruits using molecular genetic methods. Samples were obtained from apricots, plums and sweet cherry trees from region of Moravia, one sample was obtained from Myjava (Slovakia). Segments of symptomatic wood were obtained from dying stone fruit trees with very significant symptoms. This study describes detection of the fungi in the wood of 11 trees in general in 5 localities. The cultivation of the fungi from symptomatic wood and sequencing of ITS was carried out. Eleven fungal genera were determined in the stone fruits wood, particularly Irpex lacteus, Fomes fomentarius, Neofabraea corticola, Calosphaeria pulchella, Cytospora leucostoma, Phellinus tuberculosus, Stereum hirsutum, Collophora sp., Pithomyces chartarum, Aureobasidium pullulans,Fusarium sp. The results of this study demonstrate that the reason of declining of stone fruit trees in Moravia is caused probably by trunk pathogens.

Alternatives of microclimate control in orchards
209-212Views:119The aim of the study was to find out which of the methods used to avoid damages of late frosts would be the most effective for the fruit growing practice. We tested the antifrost irrigation method in Debrecen-Pallag. For that purpose microjet sprayers are used, which are thrifty and does not need for that purpose large containers. With the aim to secure an even distribution of water, the sprayers are distributed on three levels: above and inside of the crown as well as on the level of trunks. On a large scale, a single microjet above the crown level would be sufficient. By means of a detailed analysis served to set the optimum intervals between spraying phases: with each 15, 10, 5 and 3 minutes during half a minute. The synchronous presence of water and ice below the freezing point, the released freezing heat plus the water used much above the freezing point
(9–10 °C) altogether maintains the temperature above around 0 °C near the flowers or growing fruitlets, meanwhile, the surrounding air cools down to -8 °C. The effectiveness of the generally used antifrost would be increased substantially by the former application of cooling irrigation, which delays the blooming date. -
The effect of location on the incidence of brown rot blossom and shoot blight infection on apricot
89-91Views:98The aim of our study was to assess the incidence of brown rot blossom and shoot blight and caused by Monilinia laxa. Assessments of incidence were made on cv. Bergeron (susceptible to brown rot) in a flatland and a hilly growing area (at Cegléd and Gönc, respectively). In 2004, when spring and summer weather conditions were wet and cold, incidence reached 95 % for blossom blight and 33 % for shoot blight in the untreated plots. Blossom blight incidence was 1.5-2 times higher in the flatland area compared to the hilly growing area. During the blooming period of apricot, two (at flower bud stage and at full bloom) and three (at flower bud stage, at full bloom and at petal fall) fungicide applications were necessary for the successful control at Gönc and Cegléd, respectively. The difference between the two orchards was due to the fact that blooming started one week later in the hilly region (at Gönc) than in the flatland region (at Cegléd), therefore, the critical weather period coincided with blooming in the orchard in the hilly region only partially.

Comparison of growth parameters of 40 varieties/clones short rotation coppice willow (Salix)
99-104Views:123The plantation of willow varieties was established in 2009. The 40 different varieties and clones of Salix were planted at a research field in Kolíňany (Nitra district). The paper evaluates results from the first growing season in 2009. The survival rate of planted cuttings ranged from 55.56 % to 100.00 % after the first year. The lowest survival rate was reached by Terra Nova variety. The stem numbers per plant ranged from 1.17 ±0.37 to 2.53 ±0.98. The average height of one-year old stem varied from 65.82 ±36.60 cm to 225.58 ±68.61 cm. The average stem diameter ranged from 6.90 ±2.63 mm to 14.34 ±3.39 mm. There were statistically very significant differences in parameters of stem height stem diameter and stem numbers per plant among studied varieties/clones. The statistic method used was analysis of variance ANOVA. The varieties were then divided into 6 groups according to their similarity in observed parameters after the first growing season by cluster analysis. The best results were reached by varieties/clones classified in the second group. The survival rate, stem diameter and stem height values of these varieties/clones were above average.

Application of AquaCrop in processing tomato growing and calculation of irrigation water
183-187Views:292The area and volume of processing tomato production is increasing in Hungary. Irrigation is crucial for processing tomato growing. To save water and energy, it is important to know exactly how much water is needed to reach the desirable quality and quantity. AquaCrop is a complex software, developed by FAO, which is able to calculate irrigation water needs, several stress factors and to predict yields. A field experiment was conducted in Szarvas in processing tomato stands, under different irrigation treatments. These were the following: fully irrigated plot with 100% of evapotranspiration (ET) (calculated by AquaCrop), deficit irrigated plot with 50% of ET (D) and control (K) plot with basic water supply was also examined. Dry yield, crop water stress index and soil moisture were compared to modelled data. The yields in the plots with different access to water were not outstanding in the experiment. The model overestimated the yields in every case, but the actual and modelled yields showed good correlation. AquaCrop detected stomatal closure percentages only in the unirrigated plot. These values were compared to CWSI – computed from leaf surface temperature data, collected by a thermal cam in July – and showed moderately strong correlation. This result suggests that Aquacrop simulates water stress not precisely and it is only applicable in the case of water scarcity. Soil moisture data of the three plots were only compared by means. The measured and modeled data did not differ in the case of K and ET plots, but difference appeared in the D plot. The obtained results suggest that the use of AquaCrop for monitoring soil moisture and water stress has its limits when we apply the examined variables. In the case of dry yield prediction overestimation needs to be considered.

Comparison of apricot cultivars for suitability for organic growing
63-65Views:60Nowadays, important task is using more widely the environmentally friendly production technologies. There are considerable differences
among technologies using reduced spray programs (integrated and organic) in plant protection and plant nutrition.
In this case integrated production has a better position as roles for organic production more strict and due to this fruits has an obvious
temporal and permanent reduction in tree conditions. Fitotechnical elements and renewal and regeneration of cultivars are important
factors for offseting or delaying of condition weakening.
In this study, 5 apricot cultivars (not pruned for 8 years) were compared in their characteristics (assessment of inactive, semi-active and
active plant parts).
Our study showed that there were 50-70% differences among observed characteristics. Our study confirmed those cultivars which are
suitable for organic production and which one more resistant to condition weakening and which one able to tolerate negative technological
effects. -
A simplified growing model for mixed black locust (Robinia pseudoacacia L.) and poplar (Populus spp.) plantations in the Danube-Tisza Interfluve
97-100Views:95This study presents a static model of mixed black locust (Robinia pseudoacacia L.) plantation stand structures for inventory stand structures between 10 and 40 years of age. Due to its local character, the model can be advantageous in planning tending operations, making structural factor predictions for the standing stock (main stand) after tending cuts, and preparing local wood production and silvicultural models. The model data presented in this paper show that poplars account for 55–62 % of the volume per hectare due to their faster growth rate in mixed black locust and poplar plantations. Maintaining the black locust part of the stand necessitates harvesting the poplars by the age of 10 at the latest.

Strategic Steps in the Sheep and Goat Branches
61-68Views:122The balance of the sheep and goat branches can be summarised as follows:
If the increase in stock size, specific yields, genetic improvement and modernisation are not realised, several thousand shepherds will lose their jobs and possibilities to work, and their families will lose their only source of livelihood.
Several hundred hectares of grassland will become weedy and the costs of crop protection will increase in these regions. Pollen pollution, the number of allergic ailments and medical costs will increase, mentioning only the main disadvantages. Its financial requirement is nearly equal to the one required for development without any essential compensation or production.
In order to develop a competitive branch, a subsidisation of 10-20 billion HUF is needed until the accession of Hungary to the EU, depending on the scale and progressivity of development. The subsidisation and realisation of the strategic steps would result in:
– the establishment of a registered livestock with 1.5 million ewes, which would ensure better market position for the branch in the EU (5%),
– the establishment of a competitive and marketable branch with a production value of 15-25 billion HUF, calculated using the present price level (after accession, the branch would be self-operating and profitable, with the 6-8 billion HUF/year normative subsidisation by the EU),
– the establishment of a genetic potential which would ensure our participation in profitable international breeding animal market, which provides extra profit,
– the establishment of a sheep husbandry with better genetic potential and phenotypic performance, producing a quality of international level,
– the maintenance of the workplace of more than 10.000 people (saving 3-5 billion HUF/year of the budget),
– the maintenance of the condition of growing areas of grasslands with their advantages (crop protection and public health) whose financial effect is considerable. -
Fruit quality of sweet cherry cultivars in superintensive orchards
75-81Views:165The fruit quality of 15 sweet cherry cultivars (’Canada Giant’, ’Celeste’, ’Chelan’, ’Ferrovia’, ’Germersdorfi Rigle’, ’Katalin’, ’Karina’, ’Kordia’, ’Linda’, ’Regina’, ’Sam’, ’Sandra Rose’, ’Sunburst’, ’Sylvia’ and ’Techlovan’) was studied under super-intensive growing conditions at Nagykutas. We measured the fruit diameter, fruit width, fruit height, stem length and stem weight, fruit and pit weight and the total dry matter content. There were large differences among the cultivars. These differences are due to the genetic characteristics of fruits because all other conditions were the same. For 11 cultivars, we collected fruit samples several times /2-4/. We examined on this cultivars all the above listed fruit quality parameters. When examining these samples, we have gained information how earlier or later than optimal harvest time influences fruit quality.

Interactive evaluation of the main agrotechnical factors in rape production
71-79Views:78Our polifactorial rape research was carried out at Látókép Research Centre of Debreceni Egyetem AMTC, 15 km away from Debrecen. The aim was to study the unique effect and the interactive effect of more factors. The research factors were the following: cultivation, time of sowing and nutrient supply. Soil moisture datas proved unambiguously that increasing amounts of chemical fertilizer raise the water consumption of rape, lack of water in fertilized plots were always bigger then the water deficit in control plots. The highest amount of water deficit was experienced in the case of arable plots. However, increasing amounts of chemical fertilizers raised the amount of yield proportionately. We experienced yield depression only in the case of arable plots at the highest level of chemical fertilization. In polifactorial rape research sowing of 24th August 2007 of 2007/2008 was the most optimal in point of the amount of yield. This is most-significant in the case of loosening tillage and disking tillage plots, while the plots of ploughing lag behind those two in point of average yield. We experienced the biggest differences of yield in the case of different tillage plots of sowing on 24t August 2007. Still not even the plot with the highest average reached the limit of 4 tons, which can be attributed to high rate of lodging and the harvest loss caused by this. The biggest amount of yield was experienced in the case of sowing of 24th August 2007, with the highest level of chemical fertilization at loosening tillage plot (3930 kg/ha). We can observe big differences between the tillage methods; plots of loosening show a much better average yield then plots of disking and ploughing tillage. Considering the first observed crop year we can state that alternative tillage methods do have a future in rape growing of Hungary.

Regionalism in the organisation of traffic in Hungary
15-19Views:112In the member states of the European Union, especially in Germany and Austria, regionalism has a growing importance by the organising of public services. At the field of public transport services the regional organising methods will be realised through the establishment of public transport associations in interest of coordinating the local, suburban and regional public transport interests. In the period since the 90’s there are a not a lot of best practices regarding the regional organisation of public transport services in Hungary. The study goals to present the position of the local and regional interest in the public transport organisation in Hungary, and deals with the reason the lack of best practices also.

The impact of fertilisation on a few microbiological parameters of the carbon cycle
45-50Views:156The 30 years old long-term experiment of Látókép is continued in our experiments. The long-term fertilization experiment was set in 1983, and our sample was taken in spring 2014. The examinations of soil respiration processes and factors that influence soil respiration are required in optimal management. In our study, we interested to know how the growing levels of fertilization influence the microbial processes under nonirrigated and irrigated conditions in maize mono, bi, and triculture. The experimental results and those statistics suggest that the bi and triculture influenced higher microbial activity which was reflected in number of fungus, soil respiration, and microbial biomass carbon (MBC).

Impact of chronic heat stress on digestibility of nutrients and performance of meat type ducks
51-55Views:186The aim of the study is to determine the effect of vitamin and mineral supplement under permanently high environmental temperature (30±1 °C) on the digestibility of nutrients, performance and furthermore the composition of duck meat in the growing period. A total of four hundred mixed sex 14 days old Cherry Valley type hybrid ducks were used for the study. Two experimental diets were formulated in the study (control and vitamin E, C and zinc supplemented diet). Based on the results the following conclusions were drown: the antioxidant defence system plays an important role in the reduction of heat stress generated lipid peroxidation process. Feed additives which have direct or indirect antioxidant effects can reduce the negative effects of heat stress on the ducks performance and meat composition. Digestibility of nutrients (Dry Matter, Crude Protein, Crude Fat) was not affected by antioxidant supplementation under chronic heat stress (30±1 °C). The performance was affected significantly by Vitamin C and E and zinc supplementation under heat stress (P<0.05). In the treated group the daily weight gain (dWG) increased and the feed conversion ratio (FCR) was improved significantly (P<0.05). The energy and protein conversion was decreased also significantly (P<0.05).

Investigation of harvest index influencing agrotechnical and botanical factors in hairy vetch (Vicia villosa Roth.)
123-128Views:114The biggest problem of Hungarian crop farming is mass production and the simple crop rotation based on cereals. There was a decrease in sowing area of protein crops which raises crucial issues in crop rotation and land use. Therefore, growing papilionaceous plants, which are now considered to be alternative plants, should be taken under close examination. Hairy vetch (Vicia villosa Roth.) belongs to the family of papilionaceous plants and it can be grown in light weak soils.
In Hungary, hairy vetch was used as green forage at first, but it later became a green manure plant. Nowadays, it is used as a cover crop and its sowing seed has a good export market. In low fertile soils it is able to produce a big amount of green yield (25–40 t ha-1) even in spring while its seed yield could be 0.4–0.5 t ha-1 at farm level. In addition to its morphological characteristics hairy vetch is grown mainly with a supporting plant, i.e. triticale in many cases.
Our purpose was to test the harvest index and its agrotechnical and botanical factors of hairy vetch in different cropping systems.

Information Technology Supports for Student-Centered Language Education
3-6Views:74With the development of computer-mediated communication, the definition of literacy has gained broader dimensions (Murray, 1991). The ability to use new technologies to access, adapt and make intelligent use of information and knowledge is by now viewed as an additional and essential component of literacy. Today’s interpretation of literacy (often referred to as “multiliteracy”) must incorporate the communication that takes place through a growing variety of text forms associated with information and multimedia technologies.
Since it is fast becoming a basic instrument for building the literacies required for success in academic and workforce environments, used as a tool, information technology needs to become a critical component of student-centered English language education. -
Comparison of macroelement and microelement contents of conventionally and organically grown crops
87-92Views:142Nowedays one of the most important issues to discuss is the healthy nutrition: feeding our bodies with high quality nutrients, which is free of chemical residues. The demand for healthy and nutritious food is increasing worldwide, that results in the growing popularity of consumption of organic food. Several studies dealing with the nutrient content of traditional and organic food have been published lately, since it became clear that eating food contaminated with chemical residues damage to health, food and the environment. Therefore it would be desirable to find out if organic food is really superior to conventional one. In our study we analyzed the dry matter, ash, macroelement and trace element content of organically and conventionally grown crops (carrot root, potato tuber and parsnip). Our results provide further information to consumers about the nutritional value of organic and conventional crops.

The influence of climatic conditions of the harvest year on the wheat quality
23-25Views:120Technological potential of wheat bread depends on the variety, manner and type of fertilizer, irrigation conditions and climatic conditions in their absence. This study was done on two varieties of wheat grown in Bihor county in a place with identical fertilization conditions, for two different years: year 2014 can be characterized by a greater quantity of rainfall during the wheat vegetation period and the year 2015 can be characterized by a drought during the growing wheat on the subject of the study. In the study was examined whether climatic conditions have any influence on the technological potential of wheat, not taking into account the data on quantity produced per hectare in the years studied.

The effect of fertilization and plant protection in sunflower (Helianthus annuus L.) production
57-63Views:220Sunflower is the most important oil crop in Europe which is grown on the biggest area of all the oil crops. The area of producing sunflowers in Hungary was changing to 524–704 thousand hectares in the past decade in comparison with approximately 100 thousand hectares in the 1970’s. In our experiment different sunflower hybrids were examined. The doses of fertilizers were the following in 2017 and 2018: 0–30–90–150 kg ha-1 N, 0-50-90-90 kg ha-1 P2O5 and 0–70–110–110 kg ha-1 K2O. Three different treatments of plant protection were used in the experiment to protect them from fungal infections. A rise in the dosage of nitrogen resulted in increasing infection. The biggest fungal infection was identified in 150 kg ha-1 N, 90 kg ha-1 P2O5 and 110 kg ha-1 K2O treatment. The largest infection was measured on plots without plant protection at the highest N doses, both in leaf and disc diseases. We measured the highest 41.25% in 2017 and 53.1% in 2018 Diaporthe helianthi infection, and 24.5% in 2017 and 25.5 % in 2018 Sclerotinia sclerotiorum disc infection in these plots. kg ha-1
Average yield was changing between 2.96–4.67 t ha-1 in 2017/2018. The lowest yield was obtained in the absolute control plot (without plant protection and without nutrient) in both years, which was 2.96 t ha-1 in 2017 and 3.14 t ha-1. The yields increased due to growing nutrient supply and excellent plant protection. The highest yields were 3.67 t ha-1 in 2017 and 4.67 t ha-1 in 2018 (150 kg ha-1 N, 90 kg ha-1 P2O5 and 110 kg K2O active substance). Purpose of the experiment at analysing the impact of different treatments on the profitability of sunflower production.

Economic policy strategy of UNITAB
83-90Views:71Under the leadership of the International Association of Tobacco Producers – UNITAB – there is a struggle going on for stabilizing the situation of European tobacco growers. UNITAB unites the tobacco associations and tobacco growers of all EU countries.
Tobacco production ensures economic stability for more than 100 thousand small- and medium-sized farms in the rural areas of 10 EU countries. In addition, its social importance in the survival of rural communities is emphasized by the 400 thousand direct or related seasonal jobs.
Within the framework of the CAP reform, the European Union is gradually changing the regulations of production. This is based on the decoupling of subsidies, which will be implemented in two phases. Between 2006 and 2009. the decoupling will be 40% and then after 2010, 50% (the other 50% will be used for restructuring within the second pillar). The question is raised, how will the second 50% be restructured to the second pillar. Between regions and how it can be ensured that this support would go to tobacco production.
With its participation in the principles of the European Tobacco Charta, UNITAB targets for production under economically-balanced conditions, the production of products meeting the customer requirements, consideration of the working conditions (especially for seasonal workers) and adherence to the health regulations related to the consumption of the end product already in the production and environmental protection. They aim to ensure the survival of the sector via tobacco growing with sustainable development and high quality. To maintain the continuity, there is a need for the support of regional, national and EU authorities. Future of the sector is dependent upon adaptation of tobacco growers and upon meeting the social expectations.
According to UNITAB, efforts should be made to modify the decisions so that the majority of the funding could be used by the grower. The tobacco industry has been able to effectively fight for its survival. -
Quality analysis of the near-infrared spectra of wheat samples
97-100Views:120The near infrared spectroscopy is widely used in the different industries as a rapid, non-invasive analitical tool. It is suitable for identification, qualification and quantitative analysis as well. As this technique is indirect, to make accurate calibration equations we need a proper sample population. Before the quantitaive analysis, developing calibiration modells we have to collect and examine the spectra. In our study we examined wheat samples with known origins to find if there is any effect of the growing area on the NIR spectra.
