Possibilities of selection and production of blue and ornamental corn (Zea mays L.)
15-19Views:117The cultivation of alternative crops has an important role in world agriculture. Their market share is continuously growing in the food industry sector. In the present study, we show the cultivation and breeding perspectives of ornamental and blue corn. There exists possibility to cultivate ornamental corn in Hungary. There are many cultivars of ornamental corn, with various kernel colors, husks, stalks and leave colors. Blue corn is unique among other corns. Blue corn higher in protein, iron and zinc than commercial dent corn. Pests affective ornamental and blue corn are the same as those of other commercial corns. Ornamental and blue corns need to be grown a minimum of 500 m away from commercial yellow dent corn to minimize any cross pollination which may result in off-color kernel. Our aim in the presentation of this review was to broaden Hungarian literature.

Changes in the Quality of Winter Wheat Varieties in a Comparative Experiment
179-183Views:118The hungarian seed grain supply offers more and more varieties from the field crops for public cultivation in every year. The number of the admitted varieties by state doubled from 1996 to 2001. The question is what changes can the varieties newly inproved show in the quality parameters.
32 varieties admitted in different years was examined on quality parameters as wet gluten content, valorigraphic value and falling number from period 1996-2001. We established that the newer varieties surpassed the traditional varieties of the variety-comparativing experiment in accordion to they wet gluten content. In connection with formation of valorigraphical value we saw that the new varieties got place in the varieties admitted for public cultivation in quality based examining. The varieties showed different reaction of fertilizer on the formation of these two parameters. In connection with the formation of the value of falling number the examined varieties suited for the requirements of quality crop production in the experimental years excepted some of them. -
Evaluation of striptillage and conventional tillage in maize production
37-40Views:172Tillage changes soil properties and the way how the environment affects those properties. Soil properties and environment determine the rate of water movement in liquid and gaseous form into and out of soil. Based on the experimental database of the Institute of Land Utilisation, Regional Development and Technology of the University of Debrecen, Faculty of Agricultural and Food Sciences and Environmental Management and the KITE PLC, various cultivation systems were examined with maize (Zea mays L.) as indicator plant in Jász-Nagykun-Szolnok county. The sample area can be found in the outskirts of Kenderes on a meadow chernozem soil. On the examined plot, strip-tillage, subsoiling and moldboard ploughing were performed, each on 4.5 ha, respectively. The purpose of the present study is to compare these cultivation systems according to the soil- and maize kernel moisture content and to the yield based on the years of 2012 and 2013.

Characteristics of Land Use and Plant Production in Transcarpathia
290-294Views:49The character of plant cultivation and animal husbandry in different parts of Transcarpathia, are mostly determined by the location of a given region. Usually, four zones are delineated: 1. lowlands; 2. foothills and volcanic remains zone; 3. inter-mountainous subsidence and deep valley; 4. mountain zone.
In county this zone divides quite visibly. By studying the soil, climatic conditions and plants, it is not difficult to see that the vertical zones play a major role in their characteristics and formations. If we go from lower to higher elevations, we can observe the qualitative difference in the environment and, of course, in the character of agriculture.
Environmental pollution is a global problem of our age. In agriculture, the most important thing is to preserve the ideas of sustainable development, because only these can ensure the protection of production resources, which will ensure the continuous production of agricultural products. Present environmental conditions pose a more problematic challenge to agriculture. -
Correlation between cultivation methods and quality in some vegetable species
313-317Views:150Quality parameters of 5 table root varieties were tested on 3 sowing dates with different cultivation methods: open field on 15 April and 9 July 2010 and under plastic tents on 19 August. The highest red pigment content (betanin) was measured in the varieties Akela and Mona Lisa (~ 80 mg 100 g-1) of the second (July) crop. This crop is in general use in Hungary. In comparison, in the late sown varieties (August, under plastics) a further pigment increase (10–20 mg 100 g-1) was observed in the same varieties as related to the earlier sowing dates. Yellow pigments (vulgaxanthins) showed similar trends. Roots of the late sowing date (with harvest in December) contained the highest vulgaxanthin values (103.3–124.18 mg kg-1).
Varieties reacted differently to temperature changes during the production period and thus to sugar accumulation. In the second crop (July) higher water soluble solids content was measured on the average of varieties (10.12%) in comparison to the April sowing (7.76%). Beetroots of the spring sowing are recommended for fresh market while the second (July) crop with autumn harvest can satisfy industry requirements. Late sowing under unheated plastic tents supply us with fresh beetroot in late autumn and early winter and prolong the usability of plastic tents.
Six lettuce species/subspecies were tested in the open field and under plastic tents in 3 repetitions for nitrate nitrogen, vitamin-C, polyphenol (gallus acid equivalent – mg GAE 100 g-1) and mineral element (Ca, K, Mg, Na) contents. Our measurements showed lower nitrate nitrogen values under plastic than in the open field (89.10± 8.13 and 127.06±14.29 mg kg-1) on the average of genotypes. Lettuce grown in the field had higher vitamin-C content (1.4 mg%) which is nearly 50% more than in plants under plastic. The highest polyphenol content was found in samples from the field with a conspicuous value of 804.17±56.47 mg GAE 100 g-1 in Piros cikória. Samples grown under plastic were richer in mineral elements (Ca, K, Mg, Na) which can be explained by the higher nutrient content of the soil. In this environment superior Mg content was observed in Edivia (4616.33±
311.21 mg kg-1).Besides the well- known headed lettuce, Piros cikória (Red chicory),the red leaved Lollo Rossa and Tölgylevel (Oak leaf lettuce) should be
mentioned which well deserve further testing in order to supply us with nourishing, healthy food. -
Examinations of the carbon dioxide emission of the soil in the case of different tillage methods in a field experiment
209-212Views:243Today's global challenge is the increasing concentration of carbon dioxide (CO2) and other greenhouse gases in the air. The level of CO2 emissions may be significantly affected by the agriculture and, more specifically, the applied tillage method, even though to a lesser extent than industrial production. On a global scale, the CO2 emission of an agricultural area is insignificant in comparison to that of a large-scale plant in an area of the same size, but areas under cultivation, including arable land, have a large global area. In this paper, we investigated the relationship between applied soil tillage methods and carbon dioxide emissions in the case of different fertiliser treatments. In our experiment we examined four types of tillage with five different fertiliser effects. Comparing fertiliser treatments and tillage methods, it was found that their interaction significantly affected carbon dioxide emissions, the lowest value was obtained in the case of the 210 l ha-1 Nitrosol+N-LOCK – tillage radish treatment. Strip and tillage radish methods have relatively homogeneous, low value. -
Agrobotanical Analysis of Bean (Phaseolus vulgaris L.) Equilibrium Populations Suitable for Regional Land Cultivation
148-152Views:72The local bean landraces maintained at small-scale farming level should have importance as complementary source for completion of plant genetic resources with potential role in local land cultivation. Also, they should be used as primary material in breeding activities targeted on improving the foodstuffs quality. In the research were used especially landraces collected in Nyírség, Körös-mellék and Tápióvidék region. Our main objective was to reveal the relationship between the adaptation ability of landraces and the distance from their original collecting place. For that reason the location of the experimental plots was choosen by taking into account that they must be checked in each region, on it’s original region and similarly in other two different regions. On the base of the recorded agro-morphological traits we can get answers on the shaping of adaptation ability, and in the same time by a general chemical characterisation we should know more about the variation of qualitative parameters with a potential economical role. In the designing of experiment a main importance had the conditions where the research is taking place. All activities related to the maintenance of experiment were done in frame of a low input agricultural system to emphasize as much as possible the natural endowments of regeneration places.

Agronomical and Economic Evaluation of Different Soil Cultivation Systems
255-258Views:84In the interest of profitable plant production and environmental protection we have to make an effort to protect and improve the productivity of our soils while moderating production limiting factors. Due to different soil cultivation methods, the quantity of yield and required expenses also differ.
We examined the production costs in four different production technology systems. Overall, it can be said that farming standards are good, since cost prices were low (2001: 14-15 HUF/kg, 2002: 15-21 HUF/kg, 2003: 39-49 HUF/kg) in the case of all main products per 1 kg. Cost prices were lowest in the case of direct sowing, probably due to low machinery costs.
All economic indicators have to be compared when choosing the most suitable production technology in a specific farming environment. -
The Role of the 4M-ECO Agrieconomical Modell in the Crop Cultivation
170-173Views:109Today, c for agricultural use are of ever increasing significance. These provide an opportunity for more accurate planning, and favourably influence the efficiency and economic performance of given enterprise. The relevant literature divides models according to various criteria. The most common is the division between optimising and non-optimising models. Non-optimising models generally endeavour to make the best use of technological lines, machine capacity, while optimising models are used to optimise revenue returns from sales or, occasionally, production costs. In our case, revenue and returns from sales were optimised. The models examined consist of several modules. Which include the following: plant cultivation modules, evaluations (assessment of situation, conception plan, complex corporate evaluation), supplementary sheets (sheets and charts for ancillary plant production, general costs of operation, summary and crops structure optimisation). With the help of the model, annual a particular can be made for an optimal crop structure the resources of the enterprise. This it becomes possible to define the largest net revenue on a corporate level.

Establishing regional cultivating districts on the basis of the Kreybig practical soil mapping system
20-25Views:116With the help of this report evaluating the current situation of the region, characteristics of the development in agricultural production and regional differences can be clarified. By mapping out the regional soil, land use and climatic conditions and organizing these into a geographical information system, one can easily determine which plants are the most ideal to cultivate in that particular region. Moreover, it is a useful tool that enables us to
establish the most favorable land use structure suited to ecological demands and also helps to determine the methods of soil protection.
During our work, we chose administrative units in Szabolcs-Szatmár-Bereg County, based on the latest aspects of regional cultivation.
Our pilot areas are: the small regions of Nyíregyháza, Nyírbátor, Nagykálló, Mátészalka and Csenger.
Using the database, we separated and uncovered the soil conditions of the pilot areas: the chemical and physical properties of the soil layer which is exploited by the roots of the plants, the humus content, the nutrient supply, the thickness of the cultivated layer and the water management conditions.
We separated the districts of regional cultivation, where the basic elements of the traditional Kreybig color systems were applied (light yellow, dark yellow, light brown, dark green, blue, pink, red, gray, greenish brown, reddish purple, light purple, dark purple, light green).
By using the data collected from the pilot areas, we compiled a map database, which is suitable to illustrate the plant cultivating characteristics of the region. We made recommendations to determine the most favorable plants to cultivate in the specific region with the given meteorological and soil conditions, as well as for the shifting of crops.
Our recommendations were also illustrated in a map with a resolution of 1:25000. -
Alternatives of sewage sludge use in the crop production
83-87Views:118The produced plants reduce the greenhouse effect because they fix CO2 that contributes to the causing of the greenhouse effect with about 50%. The production of fertilizers is not only a costly process but it needs a considerable energy at the same time. Nowadays, the reduction of the proportion of the fertilizer is significant. One of the reasons of this is that during the production such by-products are produced in a big quantity in which the necessary vegetal nutrients can be found in a considerable measure these enrich the organic matter of soil. The latter is essential condition for the microorganisms in the soil, without which the sustainable plant cultivation can not be achieved. Besides high prices of artificial fertilizers the utilization of the wastes is economically justified. Finally the other reason for the reduction of a usage of artificial fertilizer is that the wrong use of the fertilizer may cause environmental pollutions. I examined the cultivation application of the sewage sludge in laboratory circumstances during my work.

Estabilishing Plant Production Systems by Optimising the Crop Structure
82-84Views:73In our days, ecologiacal and economic models of agricultural application are of ever increasing significance. These provide an opportunity for more accurate planning, and thus can favourably influence the efficiency and the economic situation of the given enterprise. The relevant literature divides models according to various criteria. The most common is the division between optimising and non-optimising models. Non-olptimising models generally endeavour to make the best use of technological lines, of machine capacity, while optimising models are used to optimise revenues returns from sales; or occasionally, production costs. In our case revenue and returns from sales were optimised. The models examined consists of several modules. These are the following: plant cultivation modules, evaluations (assessment of situation, conception plan, complex corporate evaluation), supplementary sheets (sheets and charts for ancillary plant production, general costs of operation, summary and crops structure optimisation). With the help of the model annual plans of plant cultivation can be made an optimal crop structure may be planned with the resources of the enterprise taken into consideration, and thereby it becomes possible to define the largest net revenue on a corporate level.

Complex evaluation of agrotechnical factors in rape seed
59-63Views:108A polifactorial field trial with rape was carried out in the crop-years of 2007/2008 and 2008/2009 at the Látókép Research Centre of University of Debrecen, 15 km away from Debrecen. The soil type of the research area was a calcaric chernozem, with a levelled and homogeneous surface. Our investigations on the dynamics of lodging proved that rape can easily be lodged under unfavourable weather conditions, which results in a significant crop failure: In crop-year 2009 yields were 1.0-1.5 t ha-1 higher than in 2008, when the weather conditions were more unfavourable. In both crop-years the influence of sowing time on the crop yield of rape was examined in three soil cultivation systems, with ploughing, loosening or disking. Different sowing time influenced the yield of rape in both crop-years significantly. In the crop-year of 2007/2008 – due to mild winter – we got the highest yield in the first sowing time (at the end of August) with loosening (3930 kg ha-1) and disking (3727 kg ha-1), while in case of ploughing we experienced the highest yield (3770 kg ha-1) in the second sowing time. There were no significant differences between the first and second sowing time (the end of August and the beginning of September), and in the third sowing time (end of September) also a moderate crop failure (-6.7%) cold be obtained, due to the favourable weather in winter and the water supply of the crop-year 2007/2008. In 2008/2009 all the three cultivation systems showed the best yield-results in the second sowing time (ploughing: 4886 kg ha-1, loosening: 5186 kg ha-1, disking: 5090 kg ha-1), and the first sowing time hardly differed from this (-4.1%), while the late September sowing time resulted in a significant crop failure of -11.1%.

Comparative study of different soybean genotypes in irrigation technology
91-95Views:314In many places in Hungary, early maturity soybean can be successfully grown. The earlier maturity group of soy which ripened in 110–125 days in most crop areas in Hungary. However, to achieve excellent results, the selection of proper varieties is important too. Successful cultivation is largely dependent on the macro and microclimate of the production area, the nutrient supply of the soil and the cultivation technology. Soybean can be produced in places where the amount of precipitation is right, as the lack of water results in lower yields and deteriorated oil and protein concentrations. In the following study, 2 years (2016 and 2017) are compared to the yield, protein and oil content of the soybeans of the early maturation group in irrigated and non-irrigated treatments. Based on our experiment, it can be stated that, during the irrigation of soybean, oil and protein content and yields did not always change.

Findings on the cultivation of potatoes in organic farming
113-116Views:101This paper explores the effectiveness of organic and plastic mulching for potato production in the Czech Republic. The mulching with chopped grass (GM) and black textile mulch (BTM) were compared to non-mulching control variant (C) with mechanical cultivation. Especially in plots with BTM were first formed ridges and covered by the black polypropylene non-woven textile and then they were planting. During vegetation the infestation of Colorado potato beetle (CPB), weeds biomass, course of soil temperature and soil water potential were assessed. The results showed that surface of GM had a positive effect on soil temperature reduction, soil water potential depression. This study also indicated a positive effect of GM on the larvae of CPB diminution, on the other hand higher incidence of larvae and higher defoliation was observed in BTM. GM had a significant effect on the yield of potatoes. The yield of ware potatoes was higher by 27 % higher on plots with GM and by 16 % lower on plots wit BTM in comparison with C. NeemAzal T/S decreased statistically significantly % of defoliation and increased yield of ware potatoes by 35 % in comparison with control.

Comparative examination of the tillage systems of maize on meadow chernozem soil
21-24Views:198Maize production plays a major role in the agriculture of Hungary. Maize yields were very variable in Hungary in the last few decades. Unpredictable purchase prices, periodical overproduction, the increasing occurrence of weather extremities, the uncertain profit producing ability, the soil degradation processes (physical, chemical and biological degradation) and the high expenses are risk factors for producers. Due soil tillage, there is an opportunity to reduce these risks. Based on the experimental database of the Institute of Land Utilisation, Regional Development and Technology of the University of Debrecen, Centre for Agricultural and the KITE Plc., various cultivation systems were examined with maize (Zea mays L.) as indicator plant in Jász-Nagykun-Szolnok country in 2012 and 2013. The sample area can be found in the outskirts of Kenderes on a meadow chernozem soil. On the examined plot, strip-tillage, subsoiling and moldboard ploughing were performed, each on 4.5 ha, respectively.
In general, our findings show, that strip-tillage and subsoiling can be alternative tillage systems beside moldboard ploughing on meadow chernozem soils in Hungary.

Effect of net shading technology on the yield quality and quantity of chilli pepper under greenhouse cultivation
5-9Views:317This study was undertaken to identify the effect of net shading technology on the total capsaicinoids, vitamin C and relative chlorophyll content expressed as SPAD (Soil Plant Analysis Development) values and total marketable fruit yield of ‘Star Flame’ chilli pepper (Capsicum annuum) for two harvesting times cultivated under modified atmosphere. ‘Star Flame’ pepper was grown under three (3) different net shading colours (white, red and green). Samples without net shading were used as control. Samples were subjected to chromatographic analyses using HPLC for the determination of total capsaicinoids and vitamin C. Interaction in shading technology and harvest times (p=0.010) had significant effect on total capsaicinoids as a result of green and white shading technologies showing higher differences when compared to control samples. Vitamin C content was observed to have increased in white and red shadings (p=0.001) after the first harvest and gradually decreased after the second harvesting time (p=0.002). Relative leaf chlorophyll content was significantly higher in white shading in the first and second harvest. Samples used as control had significantly higher marketable values when compared to white and green shadings with red recording low marketability of ‘Star Flame’ chilli peppers.

Element Content of Herbaceous Plants in the Floodplain Meadows
55-58Views:132Animals require well-balanced nutrition. The elemental content of the vegetation of meadows is influenced by as many factors such as heat, rainfall, irrigation, soil type and nutrients, meadow types, species, aspects of the vegetation period and cultivation.
Natural meadows used extensively are common sights on river floodplains. Since chemicals are banned and the species number is high, measuring the elemental composition of plants on these meadows is beneficial. Cenological survey and element content measurements were held on the rich flora of four natural meadows in the year 2001.
Weeds, in a wider sense, are plants not directly involved in growing, although their nutritional values make them important costituents of feed. Meadows are enriched by their relatively high microelement content.
On the sampling sites, the ratio deviated from the ideal 2/3 parts monocotyledon and 1/3 part dicotyledon, but this did not mean a Mn deficiency as it would have been assumed. -
Effect of sowing time and planting space on change of yield and protein content of white lupine (Lupinus albus L.)
85-89Views:183The hinge of the lupine crop cultivation technology is the sowing time and the determination of the breeding area. According to the literature the early sowing (as soon as possible to go to the soil) and larger growing area is recommended for seed production. Based on the results of our 2 years experiment, the effect of sowing time and different spacing is important on yield of white lupine, and the effect of the sowing time is more significant. A decrease in the yield was observed after later sowings. The yield and the rate of its decreasing was varied in one year and among different years depending on wheather condition and sowing time.
The role of sowing time is significant for protein content of seeds. The average protein content decreased due to the later sowings in 2014, while 2015 the protein content of seeds in early sowing time and of plants sowed 4 weeks later was similar. We measured less protein content in the 2. sowing time sowed 2 weeks later than the first one. In the studied years the average protein content of seeds from different row spaces were not different.

Examination of two artichoke cultivars under single year Hungarian climate conditions
112-115Views:82Based on the results of a previous experiment, we concluded that by choosing a suitable cultivar, it is possible to produce artichoke in a one-year cultivation system in Hungarian weather circumstances. The objective of the present experiment was to investigate the performance of two Californian artichoke cultivars (Green Globe, Imperial Star) under the local conditions. Experiments were conducted in 2002 and 2003, by using four
different sowing and two different planting dates (03.01. and 03.20. – planting 05.07.; 04.24. and 05.06. – planting 06.12.). For both cultivars, 100% of the plants initiated buds. In most of the cases, Imperial Star produced higher total and marketable yields than Green Globe did, while it formed bigger and more uniform buds. Our opinion is that the main reason for this result was that Imperial Star tolerated the dry and warm Hungarian summer much better. Irrespective of the variety by earlier sowing dates higher total yield was achieved. Based on our results, we found that under Hungarian circumstances, both cultivars could produce acceptable total yields. However, the weather circumstances of the given year influenced bud quality, and thus marketable yield, to a great extent. -
Evaluation of the microbial soil quality indicators in agricultural soils from Crisurilor Plain
79-80Views:126The researches were carried out in 2010 and 2011 on the haplic luvisol cultivated in three variant such as: pasture, cropland, and orchards. Based on the total number of microorganisms monitored in the haplic luvisol (aerobic mesophilic heterotrophs, yeast and mould, Actinomycetes, nitrogen fixing bacteria and nitrifying bacteria) was calculated the bacterial indicators of soil quality (BISQ) and was appreciate the bacterial potential of the haplic luvisol. Seasonal analyses were carried out, and annual BISQs have been calculated too. The values of the bacterial indicators of the haplic luvisol in different cultivation conditions (pasture, cropland and orchards) indicate a high density of the bacterial groups in 2010 and 2011. In 2010 the values of the BISQs are included between 3.617 (minimum in autumn, in pasture) and 5.458 (maximum, in spring, in pasture). In 2011, the minimum value (3.622) was registered in pasture, in autumn, and the maximum value (4.851) in the haplic luvisol cultivated with maize, in spring. In 2010 and 2011, based on the bacterial indicators of the soil quality values, on the first position is the cropland (4.750, 4.721) followed by orchards (4.615, 3.985) and pasture (4.537, 3.758).

The roles of mycotoxins in cereal crops production: A comparative study of Hungary and Tanzania
151-159Views:242Although Hungary and Tanzania's climatic, soil, and technological conditions differ significantly in crop production, cereals crop cultivation is of paramount importance; maize crop dominates the cultivated area (Hungary 1 million ha, Tanzania 3 million ha) both from a feed and food point of view. Unfortunately, in both countries, fungal species (Fusaria, Aspergilli, Penicillia, etc.) that produce various mycotoxins on cereals, including maize grains, are a growing concern. The situation is complicated because these fungal species and their toxins can appear not only on cereals but also on other crops. Despite the prevalence of mycotoxins in both countries, studies show higher exposure risks and contamination above tolerable levels for human consumption in Tanzania to Hungary, with Tanzania observing acute aflatoxicosis.
