Published: April 2019

The summarizing data collection of our study has been carried out in the scope of the FP7-REGPOT-2010-1 ’UD_AGR_REPO’ project as a part of the cooperation with the University of Lincoln. The University of Lincoln is an important partner of the project, the knowledge transfer activities that have been carried jointly with them are multilateral. One of the most important cooperation areas is the analysis of rural areas, rurality itself, determination of breakout points, exploration of alternative income sources, diversification possibilities. Some part of the work of the University of Lincoln on the field of rural development is based on the assessment and documentation global similarities and differences of rural areas. Present study also contributes to that work, it has been prepared on the request of the University of Lincoln with the aim of providing insight into the special political and economic changes/processes that took place in Hungary, and through them into the structure and operation of the unique Hungarian rural areas.

The study first positions the definition of rurality and rural areas into context on the basis of official EU and Hungarian legal classification. Then it covers the important agricultural nature of Hungary, which significantly determines the possibilities and properties of Hungarian rural areas. The further description of rural areas is completed by some historical summary, the introduction of ownership changes, detailed description of employment and income conditions and finally by the listing of breakout points of rural areas as a conclusion.
The role of self regulation and market mechanisms in tertiary education
Authors: Lőrincz Mónika
Published: April 2019

The social functions of tertiary education have gone through considerable changes with the transformation of economic environment in the more than two past decades. In the decade after the political transformation the number of students in the tertiary education increased more than threefold. Personal interests, social needs and the demands of the society lay different claims to the performance of this sector. The needs for structural transformation of the tertiary education system are connected with the development of social and economic processes. The changes of legal regulations determining the operation of the sector are induced by these factors, which refer to the autonomic characters of the public participants. Tertiary education possesses a specific market environment each of whose characters – both the supply and demand sides – strive for the enforcement of self-regulatory mechanisms.
Preliminary results of the phylogenetic analysis of European hare (Lepus europaeus)
Authors: Mező Blanka , Kusza Szilvia
Published: April 2019

Brown hare (Lepus europaeus) is one of the most wide spread mammal in Europe. Its genetic structure is affected not only by last glacial, even by human activities (hunting, agricultural activities), isolation of such areas or competing for food resources. According to literature datas brown hare populations has different genetic variants in Europe, however its evolution, phylogenetics has not studied well.

The main goal of this work was to know genetic structure of some brown hare. Mitochondrial DNA analysis was performed in two regions (D-loop, 513 bp and cytochrome-b, 1183 bp). Genetic distance values and Network analysis were calculated. NCBI Genbank was used for further sequences. Our results showed that Italian samples differed from the Genbank samples. We found two main clades: 1: Greece without islands; Bulgaria, Italy and Central-Europe; 2: East-Macedonia,Greece with islands, Cyprus and North Israel.
Phytoplasma diseases on fruits in Hungary
Authors: Süle Sándor
Published: April 2019

In the last twenty years, three phytoplasma diseases were identified in Hungary, viz. European Stone Fruit Yellows (ESFY) (caused by Candidatus Phytoplasma prunorum), pear decline (caused by Candidatus Phytoplasma pyri), and apple proliferation (caused by Candidatus Phytoplasma mali). Candidatus Phytoplasma prunorum was isolated from apricot, peach, plum and japanese plum. Cacopsylla pruni the vector of ESFY was also isolated and identified. Infection of Candidatus Phytoplasma pyri was diagnosed from pear and Candidatus Phytoplasma mali was found on apple and pear. The three phytoplasmas cause different damages on their host plants. The most economically important phytoplasma disease is the ESFY. It seriously impairs apricot and japanase plum trees. After infection of apricots and japanese plums show yellowing and defoliation, and within a few years die in apoplexy-like symptoms. The disease on japanese plum is so severe that this fruit practically can not be cultivated in Hungary. Pear decline is the most serious problem especially in intensive pear plantations. The vector Cacopsylla pyri, C. pyrisuga and C. pyricola can be found in almost all pear orchards. Because of the regular presence of psyllids in intensive pear orchards the insecticide control is necessary. Apple proliferation is not an important disease in Hungary. All of our isolations of ’Candidatus Phytoplasma mali’ occured in organic orchards and record was not available in Hungary lately.
The role and impact of N-Lock (N-stabilizer) to the utilization of N in the main arable crops
Authors: Papp Zoltán
Published: April 2019

The nitrogen stabilizer called N-Lock can be used primarily with solid and liquid urea, UAN and other liquid nitrogen, slurry and manure. In corn it can be applied incorporated before sowing or with row-cultivator or applied with postemergent timing in tank-mix. In postemergent timing need precipitation for long effect. In oil seed rape and autumn cereals the N-Lock should be applied with liquid nitrogen in tank mix late winter or early spring (February-March). The dose rate is 2.5 l/ha. N-Lock increases the yield of maize, winter oil seed rape, winter wheat and winter barley 5-20 %. The yield increasing can be given the thousand grain weight. In case of high doses of nitrogen it can be observed higher yield. The quality parameter also improved, especially the oil content of winter oil seed rape and protein and gluten contents of winter wheat. The use of N-Lock increases the nitrogen retention of soil and reduces nitrate leaching towards the groundwater and the greenhouse effect gas emissions into the atmosphere. The degradation of the applied nitrogen is slowing down and the plant can uptake more nitrogen in long period. The effect of N-Lock the nitrogen is located in the upper soil layer of 0-30 cm and increasing the ammonium nitrogen form. The product can be mixed with herbicide products in main arable crops.

Complexity of ecosystem services in agricultural fields, in particular the biodiversity
Authors: Csíder Ibolya
Published: April 2019

Since the Convention on Biological Diversity a lot of papers have been published how to measure and value biodiversity. In the last decades publications on agro-ecosystems become more frequent and play a significant role in the provision of ecosystem services. There is a uniform definition for biodiversity in general, however, in terms of agro-ecosystems and their services (including biodiversity) many weaknesses can be identified. The objective of this paper is to explore some of these problems with special regard to different definitions and terms and to the farmland ecosystem services. One solution could be to adopt a more complex system which has some ecological and environmental components (air, water and soil pollution) and also takes in to consideration the efficiency of agricultural production.
Dilemmas of interpreting folk culture in the cross-border regions of Hajdú-Bihar and Bihor counties
Authors: Horváth Péter
Published: April 2019

Identity connected to the dwelling-place has been, and still is, shaped by many (regional, natural, cultural, administrative, and historical) factors. The Euro region of Hajdú-Bihar–Bihor can be considered as a sort of transitional region, which has a strong impact on the cultural identity of both individuals and small communities. The identity construction of local inhabitants, however, does not necessarily follow the different geographical, ethnographical and historical borders of subregions. As a result, several transitional zones exist, which are now divided by a national border, too. Consequently, although many research theories and aspects have been conceived, no uniform method of approach has been created, which would define exactly the classification of folk culture in terms of small, medium and large region. The present short study examines problems posed by this question.

The change of the inner content parameters of table beet (Beta vulgaris L. ssp. esculenta Gurke var. rubra L.) as a result of storage
Authors: Raczkó Viktória , Rubóczki Tímea , Borbélyné Varga Mária , Takácsné Hájos Mária
Published: April 2019

The stored vegetables play a key role in the vegetable consumption. After harvesting, the storage conditions greatly affect nutritional parameters of the crop. The red beet is a root vegetable, which is manufactured mainly fresh in our county, therefore we do not have enough information about the storage. In our experiment, 5 varieties (Rubin, Akela, Larka, Libero, Mona Lisa) were examined in prismatic structure (0–5 °C and 95–97% RH) through 5 mounths.

Our measurements proved that under the appropriate storage conditions water loss was also occurs, which increased the dry matter content (average of 0.5 g 100 g-1). The bioactive compounds, like pigments (betanine and vulgaxanthin) and the quantity of flavonoids, were significantly increased during the experiment.

The results showed that the nutritional parameters of the 5 types was positive during the prismatic structure. However, this storage method negatively affected the bioactive compounds of the Akela genotype. Further studies are recommended for proper storage parameter adjustment, which is justified by the need of the different varieties. The optimal conditions enable us to preserve and to increase the best nutritional index.

Authors: Szalacsi Árpád , Király Gergely , Veres Szilvia
Published: April 2019

Photosynthetic 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 role of leaf area and photosynthesis in optimising the sowing date of maize
Authors: Bene Enikő , Sárvári Mihály
Published: April 2019

Our sowing date experiment took place in the Demonstration Garden of Institution of Plant Sciences, Agricultural Center of University of Debrecen, in 2012–2014. The thesis contains data of test year 2014. Our purpose, besides several other examinations, was to observe how sowing date influences leaf area index and activity of photosynthesis of maize hybrids, and how those factors affect fruiting. In the experiment we monitored the change of the leaf area index and the photosynthesis of hybrids with four different growing seasons.

Based on the results, it can be concluded that most of the examined hybrids reached their smallest leaf area with the third sowing date and with the highest yield results. Hybrid Da Sonka had the largest leaf area (4.10 m2 m-2), and hybrid DKC 4590 produced the highest yield (13.16 t ha-1)

with the third sowing date.

During testing the photosynthetic capacity, the extremely high performance of the youngest plants with the third sowing date is outstanding, which can be explained by the different ripening periods. Examination of the correlation between the photosynthetic capacity and the yield, by linear regression analysis, also proves that photosynthesis has a determinative role in fruiting.

The results obtained confirm that not only the environmental and agricultural factors in the growing season have effect on the yield, but also other factors like the leaf area index and the photosynthesis are determinative parameters, and all those factors together, modifying effects of each other, develop average yields.

Published: April 2019

In this study, maize (Zea mays L. cv. Norma SC) and sunflower (Helianthus annuus L. cv Arena PR) seedlings treated by molybdenum (Mo) that were cultivated in special plant growth boxes, known as rhizoboxes. During our research we tried to examine whether increasing molybdenum (Mo) concentration effects on the dry mass and absorption of some elements (molybdenum, iron, sulphur) of shoots and roots of experimental plants.

In this experiment calcareous chernozem soil was used and Mo was supplemented into the soil as ammonium molybdate [(NH4)6Mo7O24.4H2O] in four different concentrations as follow: 0 (control), 30, 90 and 270 mg kg-1.

In this study we found that molybdenum in small amount (30 mg kg-1) affected positively on growth of maize and sunflower seedlings, however, further increase of Mo content reduced the dry weights of shoots and roots. In case of maize the highest Mo treatment (270 mg kg-1) and in case of sunflower 90 mg kg-1 treatment caused a significant reduction in plant growth.

In addition, we observed that molybdenum levels in seedling were significantly elevated with increasing the concentration of molybdenum treatment in comparison with control but the applied molybdenum treatments did not affect iron and sulphur concentration in all cases significantly.

Authors: Horváth Judit , Tállai Magdolna , Mátyás Bence
Published: April 2019

The most important aim of sustainable agriculture is to ensure our natural resources – such as soils – protection, which includes fertility preservation and the use of appropriate methods of cultivation.

If we want to get accurate information about the occurred changes, way and danger of changes, we should track the resupply and effect of the mineral nutrients and the removed quantity of nutrients with the harvest.

Nitrogen is an essential element for living organisms and it is present in the soil mainly in organic form. In general only a low percentage of the total nitrogen content can be used directly by plants in the soil. The mineral nitrogen is incorporate by plants into our bodies. This inorganic nitrogen is produced by the transformation of organic contents through mineralization processes and it gets into the soil by fertilization. This is how nitrogen turnover occurs when mineral forms become organic and organic forms become mineral.

The objective of this publication was to introduce – through some element s of nitrogen turnover- how changing the properties of soil in a long term fertilization experiment.

We established that the fertilization is influenced the soil pH. With the increase of fertilization levels increased the acidity of the soil, maybe it is related with the number of nitrification bacteria. The fertilization and the rotation affected to the quantity of nitrate.
Production technology development of millet at different ecological conditions
Authors: Seres Emese , Sárvári Mihály
Published: April 2019

The millet is a very special plant with good adaptation that gives the possibility for the late sowing and secondary production. However the effects of late sowing modifies the efficiency of the agrotechnological elements. The exainations – focused on this aspect – was conducted in the DU RINY and DU RIK in small plots in four replications in 2014. Among the examined factors (sowing time, nutrient supply, growing area) sowing time had the largest effect. The effectiveness of the agrotechnological elements decreases under unfavourable circumstances caused by the late sowing.

The agrotechnical elements modifies the yields in the examined genotype. Sowing time had the biggest effect on the yields of millet. The genotype „Maxi” had the highest yield in the different treatment variations.

The yield differences were significant between the sowing time and plant density variations, but the nutrient supply had not significant effect (the rate of precipitation was unfavourable in 2014 season).
The impact of grain maize and sunflower as previous crops on the yield and ear number of winter wheat in a long-term experiment
Authors: Szilágyi Gergely
Published: April 2019

We have analyzed the effect of grain maize and sunflower forecrop on three different winter wheat genotype (GK Csillag, Mv Csárdás, Mv Toldi) regarding to the spike number and yield in different fertilization levels in the 2012/2013 cropyear. According to our data after sunflower forecrop we reached higher spike number and yield, which were influenced by the differences of the varieties. We found significant differences between the varieties in the control treatment. According to our research, GK Csillag has reached the highest yield in the examined fertilization levels and forecrop models too.

Authors: Várallyay Szilvia , Veres Szilvia , Garousi Farzaneh , Bódi Éva , Kovács Béla
Published: April 2019

The environment is contaminated with heavy metals and other toxic compounds. One of the most important toxic element is the arsenic (As).

The objective of our study was to investigate the effect of As on fresh and dry weight of sunflower and maize in the early growth phases.

Seedlings were grown in climate room on nutrient solution which were treated with 3, 10 and 30 mg kg-1 arsenic. The plants were treated separately with As(III) and As(V). After 14 day, changes in fresh and dry weight of maize shoots and roots were recorded. In the case of sunflower these parameters were measured after 21 day.

The applied As(III) and As(V) decreased the fresh and dry mass of the shoots and roots of seedlings, especially at concentration 30 mg kg-1. We can draw the conclusion that the treatments of the maize and sunflower roots with arsenic had negative effects on the biomass accumulation. We found that the sunflower plants are more sensitive to arsenic toxicity than maize plants, and all data demonstrate that the As(III) is more toxic to these plants than the As(V).

Published: April 2019

For the appropriate quantity and quality of fish meat the pond farmers need to use up to date nutrition and feeding technologies. Recently the intensification of the carp production is stepping up with the availability the proper quality of the artificial feeds. The using of different feed additives make a better feed conservation ratio, faster growing rates and more uniform stocks.

In our experiment what is made with common carp (duration of the experiment was 8 weeks long) we compared two different kinds of feed additives in different doses. One of them contains only natural mineral elements and the other additive is a natural origin probiotics. Both additives were used in the quantity of 0.5, 1 and 2% of the total feed. By the result of the 8 weeks experiment it could be said, that the using of the humic acid based mineral elements feed additive. Makes a better FCR comparing with the control stock, but was not as good as the using of the probiotics. At the humic acid treatments the more doses, the better FCR value, but at the probiotics it wasn’t true. The 0.5% probiotic treatment gave the best result. It is concluded that the using of the probiotic feed additives always gave a better performance of the fishes (average weight, biomass, FCR) than the humic acid treatments. The using of the feed additives hasn’t got an influence for the survival rate of the carps.

Published: April 2019

Sow milk production is the major factor limiting pig growth to weaning. Although the milk production of the sows incremental many environmental factors affect the actual performances. The supplemental milk replacer can be an appropriate solution to ward off disparities and try to equalize the available milk quantity to the piglets according to their appetite, to enlarge the weight of pigs at weaning, ultimately. The aim of the present study was to investigate the effects of liquid milk supplement on weight development and litter performance of the piglets during the suckling period. Data were collected from 60 farrowings, the weight of 649 piglets in a total were measured at birth, 14 days old and at weaning (28 days), respectively. In the control group (n=319) the piglets were suckled and got prestarter feed from day 10. In the experimental group (n= 330) the piglets had got liquid milk replacer in 10.71% solution, from day 10 after birth together with suckling and prestarter feed, as well. Based on the Duncan's multiple range tests, there were no significant differences in birth weight between the control and experimental group but we found significant differences between the 14 days weight and the weaning weight, subsequently. Based on the CV% of weight the experimental group became more homogenous, in contrary to the weight of the control group at the end of suckling period. The milk supplementation can be an appropriate solution to ward off disparities and to equalize the available milk quantity to the piglets according to their appetite, to enlarge and uniform the weight of pigs at weaning, ultimately.

Authors: Nyilasovits Andrea , Posta János , Czeglédi Levente , Babinszky László
Published: April 2019

The contractile protein, which is encoded by troponin I 1 (TNNI1) gene, is located on the thin filaments of slow fibres in striated muscle. TNNI1 protein is a part of the troponin complex which plays an important role in regulation of muscle contraction by preventing actin-myosin interaction in absence of calcium. According to biological role, this gene can be potential marker for meat production related traits. The aim of this study is to define whether the previously reported gene polymorphism (EU743939:g.5174T>C) is connected with the slaughter traits measured in a standard slaughterhouse of the examined four-line European hybrid. The study included data from 404 gilts and barrows from 2 different samples. The polymorphism was detected using PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) method with XbaI restriction enzyme. In this study the allele frequencies were found as follows: C: 0.84 and 0.808; T: 0.16 and 0.192. Based on result of the present study no significant impact of polymorphisms on production parameters was found.
Role of hypothalamic neuropeptides in feed intake regulation of livestock species (literary review)
Authors: Simon Ádám , Jávor András , Czeglédi Levente
Published: April 2019

Energy balance is the net result of the energy intake (nutrition) and expenditure (basic metabolic rate). The purpose of the daily feed intake is to provide energy and nutrients for maintenance, production and fill and maintain energy storages in form of glycogen and fat. Animals can adjust their feed intake to ensure their energy demand. Food intake regulation in animals and human is a very complex process, in which the digestive system, the central nervous system, the joining hormonal and non-hormonal factors, and the integrating hypothalamus take part. This review primarily focuses on the action mechanism of some important appetite regulating neuropeptides, and their impacts on the performance traits of the economically significant animal species.
Let's talk about 'One fungus One name'. Changes in the fungal taxonomy
Authors: Kövics György
Published: April 2019

Mycologists have recorded a few hundred thousand Latin names for fungi and these are thought to refer to 70 000 or so separate species. The use of molecular techniques in fungal taxonomy and systematics in the last 25 years has provided massive amounts of information to clarify phylogenetic relationships, encouraged grant support, and complicated the jobs of classically-trained mycologists. Taxonomists have a reputation for being traditionalists, but the community has recently embraced the modernization of the nomenclatural rules by discarding the requirement for Latin descriptions, endorsing electronic publication, and ending the dual system of nomenclature, viz. teleomorph and anamorph names, which used parallel for the sexual and asexual phases of pleomorphic species. A group of taxonomists accepted ’The Amsterdam Declaration on Fungal Nomenclature’ and its basic principle the ’One fungus – one name’ has been incorporated in the Code of Nomenclature (’Melbourne Code’) in 2011. The next, and more difficult step will be to develop community standards for sequence-based classification. As the’One fungus – One name’ theory is a brand-new issue for the Hungarian plant doctors and practical specialists, it seems reasonable to review this to promote conversations between generations in Hungarian language.

Published: April 2019

The phytotoxic effect of herbicides applied post-emergence was investigated in a herbicide sensitivity experiment set up on parental maize genotypes in Martonvásár. A total of 48 Martonvásár inbred lines and 12 single line crosses were included in small-plot experiments set up in two replications. Ten herbicides were applied at the normal authorised rate and at twice this quantity. Compounds intended for pre-emergence application were applied when maize was in the 3–4-leaf stage and post-emergence herbicides in the 7–8-leaf stage of development. The extent of phytotoxicity was scored two weeks after treatment. Some of the herbicides tested are not authorised for use in seed production fields, but it is important to know how the parental genotypes respond to all types of herbicides. Phytotoxic symptoms of varying intensity were only observed on a third of the 60 parental genotypes examined; the majority of the lines exhibited no reaction to any of the herbicides. Averaged over the 60 genotypes the level of phytotoxic damage was less than 10% for the single dose. When the double dose was applied somewhat more severe damage was induced by products containing Mesotrione + Nicosulfuron or Foramsulfuron + Isoxadifen-ethyl, but this was still below 15%. The herbicide dose had a three times stronger influence on the intensity of the symptoms than the type of herbicide. With the exception of Topramezone, there was a significant difference between the effects of the normal and double doses. The greatest dose effect differences, in decreasing order, were observed for Mesotrione + Nicosulfuron, Foramsulfuron + Isoxadifen-ethyl. Nicosulfuron and Mesotrione + Terbutylazine. The Mesotrione + Terbutylazine active ingredient combination only caused mild (<10%) symptoms on a total of 11 genotypes, while the Mesotrione + Nicosulfuron combination induced more severe phytotoxic symptoms on 26 lines. When Nicosulfuron was applied alone it caused milder symptoms on fewer genotypes than in combination with Mesotrione. Among compounds of the sulphonyl-urea type, the least severe symptoms on the fewest genotypes were recorded in the case of Prosulfuron.
Contributions to the 2014 and 2015 flight pattern and damages of Carpomyia schineri Loew.
Authors: Voigt Erzsébet , Kelemen Dóra , Tóth Miklós
Published: April 2019

The fly Carpomyia schineri Loew is a pest of the berries of the feral Rosa canina group but is can also be found in the berries of grown rose cultivars. The larva damages the flesh of the berry, several larvae can develop inside a single berry. It can decrease the quantity and ascorbic acid content of the tea and jam, which are important human ascorbic acid sources during winter. At the same time in trapping experiments the adult can be confounded with adults of the walnut husk fly (Rhagoletis completa Cresson). In collections of berries at several sites in Hungary damage levels ranged from 0.88% to 65.08 %. Based on these damage levels we had the impression that the yellow sticky traps CSALOMON® PALz or PALs baited with the synthetic Rhagoletis lure caught moderate numbers of adults and were not satisfactory for detection, consequently improving trapping methods is necessary in the future.

Observed were claw traits as claw angle, claw length, heel index, claw height, claw diagonal and claw width. Right hind claw after functional trimming was evaluated. Occurrence of claw disorders like interdigital dermatitis and heel erosion (IDHE), digital dermatitis (DD) and sole ulcer (SV) as well as the progress of disease were observed. Basic summary and variation statistics was performed by the SAS software. Two herds were included in the study. Holstein dairy cows (n=101) produced 11 875 kg of milk, 468 kg (3.94%) of fat and 396 kg (3.34%) of proteins. Holstein cows were affected with IDHE in 22 cases, with DD in 6 cases and with sole ulcer in 10 cases. Slovak Simmental dairy cows (n=101) produced 5834 kg of milk, 258 kg (4.44%) of fat and 209 kg (3.59%) of proteins. Slovak Simmental cows were affected with IDHE in 8 cases, with DD in 5 cases and with sole ulcer in 19 cases. Observed was that claw disorders caused deviations of milk production.

Published: April 2019

The effect of reduced and conventional tillage on soil compaction, soil moisture status and carbon-dioxide emission of the soil was studied on a meadow chernozem soil with high clay content in the soil cultivation experiment started in 1997 at Karcag Research Institute. Our investigations were done on stubbles after the harvest of winter wheat and winter peas after the very droughty vegetation period of 2014/2015.

We established that the soil in both tillage systems was dry and compacted and the CO2-emission was very low. The positive effects of reduced tillage could be figured out only in the soil layer of 40–60 cm in the given weather conditions of that period.

Technological 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.
Analyses of a few physiological parameters of hybrid wheat in the case of different nitrogen supply levels

The winter wheat is one of the most determinant crops because its role was always important in human’s life. To increase the average yield there are several possibilities, which are still not clear fields of agricultural plant production. Our main goal was to examine the responses of winter wheat genotypes to different amounts of nitrogen supplies. The sowing area of hybrid wheats are increasing, they may have different nutrient nitrogen utilization compared to varieties, and the question arose if it is possible to achieve same yield at lower nitrogen fertilizer application or not.

The present study analyzes the results of winter wheat (Triticum aestivum L.) from tillering growing stage. Under controlled conditions three different wheat hybrids were grown (Hywin, Hystar, Hybiza) with two different amounts of nitrogen supplies (optimal and the fourth part). The dry matter accumulation, relative chlorophyll content and nitrogen content were measured in order to draw conclusions from the different supplies of nitrogen for winter wheat genotypes and their physiological plasticity.
The examination of the marigold’s (Calendula officinalis L.) nutrient requirement in small-plot trial

During our research we investigated the marigold's (Calendula officinalis L.) nutrient requirements with different fertilization treatments in small-plot trial. We measured the harvested marigold's drug's raw and dry weight on a weekly basis from July 6th until August 17th. We were using SPME (Solid phase microextraction) and GC-MS (gas chromatograph-mass spectrometer) to examined the effects of the different fertilization settings for the herb's main active ingredients of essential oil's percentage.

It was concluded, based on the results, the N30P40K60 fertilization setting is ideal in terms of the quantity of the marigold drug. Both the raw and the dry weights' measurements of the case, this fertilization setting have the most important effect on the herb's yield. The analysis of variance didn't show significant differences between the plots with different fertilization settings. We discovered relationship between the drying loss and the increasing quantities of nutrients. We think it may be possible the Alpha-thujon's and Alpha-cadinol's production and the drying loss's data are connected, which appear to confirm the N15P20K30 treatment's data.

The aim of the present study was to examine the efficiency of paraffin oil against powdery mildew in Eger wine region. The experiment has been carried out in 2013 and 2014 with Chardonnay and Kékfrankos grape varieties, which have different resistance against powdery mildew. The effectiveness of the oil was examined on leaves and clusters (frequency and intensity). This oil was effective against Erysiphe necator infection on field trials in Chile and Brazil. The spread of downy mildew (Plasmopara viticola) was also inhibited by this material in some experiments conducted in Spain and France.

The differences between oil treatments represented the sensitivity of the grape varieties in accordance with the applied dosages. The oil was effective against powdery mildew with different extent as a result of the so called ”vintage effect”. In 2013, the treatment of the highest dosage (D3) didn’t differed significantly in frequency and intensity of infection from the regular treatment (clusters of Kékfrankos, leaves of Chardonnay). In 2014, the oil was not so effective against powdery mildew compared to 2013. No remarkable differences were detected between the treatments due to the strong pressure of powdery mildew. Furthermore, no any effect of the lowest dosage (D1) was detected in the case of the sensitive clusters of Chardonnay and leaves of Kékfrankos in both experimental years.

In summary, the oil treatment has an effect against powdery mildew, however this efficiency largely depends on the vintage characteristics and the pressure of powdery mildew. Further investigations are neccessary, for example field trials with combinations of other sprays. The oil can be useable as fungicide with proper care in eco-friendly integrated and bio (ecological) viticulture.
Development opportunities for storing and displaying of spatial data in long-term experiments
Authors: Ragán Péter
Published: April 2019

Long-term experiments are required to evaluate the impact of irrigation, nutrient utilization, and year factor as well as to assess the potential consequences of climate change. However, in the long-term experiment, it may be necessary to display spatial data for each parcel, either for investigation of soil heterogeneity or presentation. This article aims to provide help for researchers working in long-term experiments for storing and displaying spatial data.

After the outlines of each experimental site were measured with GPS, a spatial database has been created in Quantum GIS. Then, a filter script in R statistical environment using RStudio graphical interface was written. The script helps avoid the QGIS data input interface so that large data can be attached to each parcel directly and as a result there is no need for a separate data entry, only the basic statistical database.

The created GIS database can be used in many ways; it can be exported to KML file format that can be displayed using Google Earth. It is possible to view exported KML files in Google Drive with importing them to Google My Maps application, and with that a browser can display the map. With the Google Drive the maps can be shared within the research group, additionally the outlines can be edited and it is possible to upload the measurement data to the attributes table to existing empty table columns. The map created in Quantum GIS can be used for presentation purposes.

Published: April 2019

We made plant physiology examinations in Arkaso winter oilseed rape hybrid substance: relative chlorophyll content (SPAD) and leaf area index (LAI) measurements. The experiment was set in University of Debrecen Agricultural Sciences Center at Látóképi Experimental Station in four replications, in two different sowing times (I. sowing date on 08/22/2014 and II. sowing date on 09/09/2014 sowing againhappened because of the incomplete germination in the second subtance 01/10/2014) Three different plant density 200, 350 and 500 thousand ha-1, under the same nutrient supply, 45 cm row spacing. The experiment was green crop of winter wheat. The relative chlorophyll content (SPAD) and leaf area index (LAI) measurements were made in seven different times. We measured the maximum value of chlorophyll content in the first sowing time at 500, and the second sowing time at 350 thousand ha-1 plant density. The measurement results proved that there was a linear relationship between the number of plants and the LAI. The maximum leaf area index values we measured in both the sowing time at 500 thousand ha-1 reached.
