Examination of French bean on organic and conventional farming of Research Centre of Nyíregyháza
Published September 2, 2009
87-98

This study presents the yield results of some French bean varieties in organic and conventional farming. This study presents the advantage of organic farming in environmental point of view and in nutrition. Sale of organic products is insured, there is solvent demand rather in abroad than in Hungary.
In Research Centre of Nyíregyháza had m...ade organic farming since 1994, at present on 74 hectares.
In the first trial, variety comparison with 9 yellow podded French beans in organic and conventional farming was conducted. Varieties: Carson, Cherokee, Debreceni sárga, Goldmine, Héliosz, Minidor, Sonesta, Sundance és Unidor. The following parameters were observed: the time of emergence and flowering, number of plants per plot, plant height and flowing green harvest. We weighed yield of the standardized, un-standardized and diseased pod fractions. The results were evaluated statistically with SPSS and Excell softwares.
Emergence had all at once, but the plants of organic farming were 5 days earlier at flowering and maturity, than conventional farming.
The plants in organic place were more developed than in conventional ones. Emergence was more uniform, the growth and the number of plant were square. Significant difference was not detected in plant height between two places. Most of the varieties examined had better total yield in organic place, than in conventional ones. Deviation depended on variety. ‘Sonesta’ and ‘Debreceni sárga’ had the best yield in both places. In
conventional farming choice can be expanded with ‘Unidor’ and ‘Sundance’. In organic farming choice can be expanded with ‘Minidor’ and ‘Carson’.
In both places the Sonesta, Debreceni sárga and Unidor varieties had the most standardized yield per hectare. In organic place Carson variety had good pod yield because it was infected less by diseases.
In the another trial we studied inside content values of some varieties on organic and conventional places. The parameters were observed: dry matter-, starch-, crude fibre-, crude protein content and amino acid content.
The rates of asparagin or glutamine acid were the highest, which was followed by serin or histidine. In asparagin content was the most deviation between conventional and organic farming.
Significant differences were between varieties in dry matter-, starch-, crude fibre-, and crude protein content both on organic and conventional places. Each variety had significant differences between organic and conventional farming.
Starch had strong and negative correlation with dry matter, crude fibre and crude protein content.
Budai piaci and Minidor varieties and BU-16 variety candidate had higher starch content and lower dry matter, crude fibre and crude protein content on organic place. Sonesta variety had almost equal dry matter content on both places, but crude protein content was higher with 10% and starch content was lower with 6% on organic place, than on conventional place. Paridor variety had almost equal starch content, but it had higher dry matter and crude protein content on organic place.

Feeding questions of organic lamb fattening
Published June 5, 2009
155-160

Organic farming has done in line with conventional farming in the Karcag Research Institute of DU CASE since 2001. Our organic farming activities were enhanced with sheep farming and
grassland management in 2005. We started our study of technology development of organic lamb fattening and the treatment of its economic effect this year. Our g...oal was to develop
the elements of the technology to reach a more efficient organic lamb fattening. We also studied what economic advantages the organic sheep farming could realize in the present economic environment. Our studies were carried out between 2005 and 2007. We established that the excellent ewe feeding (good quality of fodder and silage) can decrease the lamb feeding cost between the 2nd and 8th weeks of the lambs’ life. We established that the
yield of convention lambs are significantly higher than the yield of organic lambs. The cost of organic lamb fodder is significantly lower than the cost a convention lamb fodder, but the profit was higher in the case of convention lamb fattening. The organic lamb fattening technology (without extra price) is not competitive to the conventional lamb fattening technology. We think that the profitability of organic lamb fattening is significantly less than of the convention one. The organic lamb price should be 20-30% higher than the other price to be competitive.  Unfortunatly there is only a little demand for organic lamb and there is no difference between the prices of organic and convention lambs, so organic sheep farmers have worse economic circumstances than conventional sheep farmers.

New challenges in soil management
Published September 5, 2018
91-92
Soil management represents two important tasks that are harmonization of the soil protection with demands of the crop to be grown on the given land under prevailing farming condition. Further goals are to preserve and/or develop the soil physical, biological and chemical condition and to avoid the unfavourable changes of the soil biological a...ctivity and the soil structure. Classical authors emphasised the importance of creating proper seedbed for plants. In the physical approach, tillage was believed to play an important role in controlling soil processes. Consequently, the period of several centuries dominated by this approach is referred to as the era of crop-oriented tillage (Birkás et al., 2017). The overestimation of the importance of crop requirements resulted in damaging the soils, which inevitably led to turn to the soil-focused tillage. Since the first years of climate change, as the new trends have raised concern, tillage must be turned into a climate-focused effort with the aim of reducing climate-induced stresses through improving soil quality.
The development of soil management has always been determined by the economical background. At the same time, deteriorating site conditions have contributed to the conception of new tillage trends by forcing producers to find new solutions (e.g. dry farming theory in the past or adaptable tillage theory nowadays). Győrffy (2009) recited the most important keywords were listed in 2001 and that seemed to be important in the future of crop production. These keywords (endeavours) were as follows:
− Biofarming, organic farming, alternative farming, biodynamic farming, low input sustainable agriculture;
− Mid-tech farming, sustainable agriculture, soil conservation farming, no till farming, environmentally sound, environmentally friendly, diversity farming;
− Crop production system, integrated pest management, integrated farming, high-tech farming;
− Site specific production, site-specific technology, spatial variable technology, satellite farming;
− Precision farming.
Győrffy’s prognosis proved to be realistic and the efforts mentioned above have mostly been implemented. New challenges have also appeared in soil management in relation to the last decades. The most important endeavours for the future are:
1) Preserving climate-induced stresses endangering soils.
2) Turn to use climate mitigation soil tillage and crop production systems.
3) Applying soil management methods are adaptable to the different soil moisture content (over dried or wet may be quite common).
4) Use effectual water conservation tillage.
5) Use soil condition specific tillage depth and method.
6) Adapting the water and soil conservation methods in irrigation.
7) Preserving and improving soil organic matter content by tillage and crop production systems.
8) Considering that stubble residues are matter for soil protection, humus source and earthworm’ feed.
9) Site-specific adoption of green manure and cover crops.
10) Applying site-adopted (precision) fertilization and crop protection. Considering the development in agriculture, new endeavours will occur before long.

Current Conditions and Opportunities of Biofarming in Hungary
Published May 4, 2004
150-156

The aim of organic farming is not to maximize income, but to achieve optimal product quality. It is completed by the tightest possible material, and energy flow within the farm. Organic agriculture significantly reduces external inputs by avoiding the use of chemo-synthetic fertilizers, pesticides and pharmaceuticals. Instead it works with natu...re to increase both agricultural yields and disease resistance. Total independence of external resources can not be achieved in Hungary due to the small-scale of organic animal husbandry. Some materials in limited quantities can be purchased from external resources, though the group of these materials is strictly regulated. Organic farming harmonizes with the concept of European multifunctional agriculture, because besides farming, it includes social considerations, as it helps to maintain natural resources and the relationship between people and their environment, and provides a living for those living in the region.
As regards organic farming the fertility of the soil and the health of vegetation can be influenced in various ways. Farmers have to be highly skilled and able to manage a farm with great expertise. Generally it can be stated that as the use of non-organically produced products is limited, the opportunities to correct failures made by the farmer are minimal, contrary to conventional farming. Farmers must be intent on developing the tightest material- and energy flow. This means that organic farms ideally have both animal husbandry and crop production. This energy and skill demanding system of farming is compensated by state subsidies, growing market share and relatively high prices for organic products.

The Role of Organic Farming in Hungary and in the Northern Plain Region
Published December 6, 2005
273-276

In 2003, the area, which was monitored according to the requirement of organic farming, was 116 thousand hectares in Hungary, and included almost 1700 works, which produce organic products. This is some 2% of the cultivated land of Hungary. The increase of organic farming areas has slowed down in recent years. In these conditions the optimal 30...0,000 hectares cannot be achieve in 2006.
In 2003, the area which was cultivated according to the regulations of organic farming was more than 33 thousand hectares in the North Great Plain Region, and monitored 250 enterprises the associates of the monitor organization. The challenge of the coordinators of the organic farming in the region are to fortificate the processing industry. The goal is to increase the added value of the products.

Economic Aspects of Winter Wheat and Sunflower Production Under Organic Farming Methods
Published May 4, 2004
256-261

On the basis of data from selected organic crop producing farms around Hortobagy and a significant conventional agricultural enterprise, the efficiency calculation of two important crops, winter wheat and sunflower were compared to each other, according to the organic and the conventional farming methods. The analysis was carried out on the bas...is of data of the year 2002, helped by the calculation and the comparison of the efficiency indexes. According to the results, the organic winter wheat was more highly profitable in 2002 than the conventional one, and this is because the price ratio of the two was quite high, however the yields and the production costs per hectare were almost on the same level. Considering the sunflower, organic farming was less productive than the conventional one in 2002, as the average yield in the examined organic farms was significantly lower than under the conventional farming method, and this was not compensated by the extra price for the organic crop product.

Name Brands and Symbols Used Organic Products in the European Union and in Hungary
Published May 4, 2004
174-180

In 2002, the area which was monitored according to the requirements of organic farming numbered 103 thousand hectares in Hungary (this is some 1.7% of all cultivated land) and almost 1000 plants producing organic products were inspected. It is a realistic assumption, when considering these data, that within a short period time the area used for... organic farming will reach the optimal 600.000 hectares.
Contrary to overproduction in the EU – cereals, maize and other plants – organic products can be sold in unlimited quantities. Practice also indicates, that 90% of Hungarian certified organic products are sold in EU and Swiss markets.
Thus, it is important to label Hungarian products according to EU standards. This way standard quality products can be sold easier and by increasing their income, manufacturers can contribute to the improvement of the environment.

Yield and sward composition responses of a native grassland to compost application
Published August 29, 2017
35-38

A major part of the animal products are based on the grasslands, due to the fact that the grassland ecosystems can be found all over the globe. In places where economical and successful crop production cannot be realized, the grassland based animal husbandry can be an efficient way of food production. In addition these ecosystems have an import...ant role in carbon sequestration, and with their rich flora – and the fauna connected to it – in conservation of biodiversity. The protection of nature, and the sustainable agriculture is getting more and more attention in the European Union, but looking at the consumers’ needs, the production of healthy food cannot be neglected either. Because of these facts, the effects of two specific composts - which are officially authorized in organic farming, in Agri-environment Schemes and Natura 2000 programs – on grass yields and sward compositions were investigated in a field trial. The investigation took place in Hungary, on a natural grassland based on solonetz soil. The first type of compost was a natural one (N) without any additional material and the other one was enriched in phosphorus (E). Both was produced by the research institute, made of sheep manure. Three rates of compost (10 t ha-1, 20 t ha-1,30 t ha-1) were tested on 3 m×10 m experimental plots. Every treatments had four replications and both type of compost had four-four control plots too, this way 32 experimental plots were included in the investigations. The yield of the pasture was harvested two-times (in May and in September) and before cutting the plots measurements on botanical compositions were made. Samples for laboratory analysis were also taken. Dry matter yield and crude protein content was measured in laboratory and with the received data the yield per unit area was calculated. Based on the research results we can say that the application of compost in any dose inflicts higher dry material and crude protein yield. The changes were partly due to some positive changes in sward composition, because of the better nutrient conditions. The research results indicate, that use of organic compost can be an efficient way to increase grass yields in a sustainable way.

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">Nowadays the success vegetable and fruit production are unimaginable without regular nutrient management. The animal husbandry is getting decrease, thereby there is the lack of organic fertilizer and it is suggested to find alternative nutrient supply methods. One of the ways to supply the required nutrients in an environmentally friendly way is the application of composts, which is less widespread so far, which is appropriate for the requirement of organic farming.

From the year of 2010 in each year, compost doses were applied in biological apple orchards in cooperation with the Institute of Horticultural Science. In the function of the years different changes were resulted by the compost treatments in the examined parameters in case of both apple species (Golden Delicious and Pinova). It was concluded that the dry matter, ash, total acids, sugar content and the vitamin C changed versus time and species. It is supposed that the effect of compost treatments is getting visible.

According to the data higher dry matter, total acids and sugar content, (in some cases) ash were measured in case of the apple species Pinova, while the measurements showed higher vitamin C content in case of the species Golden Delicious.

Findings on the cultivation of potatoes in organic farming
Published November 20, 2011
113-116

This 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 polypr...opylene 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.

The effect of compost made of sheep manure on the first cut of a semi-natural grassland
Published December 28, 2018
25-29

In an experiment, two types of compost were tested on natural grassland in order to improve the productivity of a natural sward on solonetz soil. Both composts were made of on-farm produced sheep manure, but the second one was enriched in phosphorus. These fertilizers/composts are officially authorized and can be applied in organic farming. Zer...o application and three rates of fertilizer were tested (10 t ha-1, 20 t ha-1, 30 t ha-1) on 30 m2 experimental plots wit four replications. Dry matter, crude protein and net energy content for maintenance were measured and determined and their yields per unit area were calculated. We found that all the treated plots produced significantly higher yield than the control ones, and in some cases the yields were almost three times higher. However, the optimal compost dose varied, depending on the examined parameter. Based on the evaluation of the experiment results along with rainfall data, it was concluded that, with higher precipitation, the positive effect of the compost application was bigger. The difference between the natural and enriched compost is remarkable, but it has to be mentioned that even the natural compost showed good results; therefore, it is also effective in improving the fertility of grassland.

Stress Response of four Common Carp (Cyprinus carpio L.) Varieties with Different Genetic Background
Published May 11, 2003
26-29

Four different carp varieties were tested for stress reaction, with the help of 10 °C cooling and 100 g/l crowding. The selected varieties represented a broad genetic spectrum of carp species. The stress was monitored by measuring plasma cortisol, glucose and lysozim levels. In each test different varieties showed significantly different react...ion to stress. This means that they differ in the trait of general resistance. Thus, this trait can be used in selection programmes and the acquired information helps to understand fish-environment interaction and specific resistance. These traits should be used in selection to improve the breeding of new more tolerant species for intensive farming or for organic production.

Mitigation of the effect of secondary salinization by micro soil conditioning
Published May 20, 2020
115-119

This research has the general goal to meet the customization of agriculture in small scale farming. We are developing a technique using micro doses of soil conditioners and organic material applied in the root zone of vegetable crops. We expected to change the physical and chemical properties of the affected soil, which has been irrigated w...ith salty water. Two different soil conditioners were tested. A lysimeter experiment including 8 simple drainage lysimeters was set up in the Research Institute of Karcag IAREF University of Debrecen in 2017. The main goal was to study the effect of different soil conditioners on the soil endangered by secondary salinization induced by irrigation with saline water. In order to compare the difference between the treatments, we collected soil samples, water samples, and determined the yields. Chili pepper (Capsicum annuum) was used as an indicator crop during one specific agricultural season. The technique called micro soil conditioning is rational because several reasons. The roles of the technique are various, for example it can serve as a source of carbon or a container for soil amendments and can minimize evaporation. We found this technique not to interfere with the chemical reaction or the interaction with the plants. However, the micro doses of soil amendments had the role to minimize the risk of soil degradation and do not significantly influence soil respiration. In addition, by improving soil properties, soil conditioning increases the leaching of the excess of salts from the root zone. In fact, this technique can decrease the cost of the inputs and improves the production of vegetables, and at the same time mitigates the effect of secondary salinization.

Economic Aspects of Rural Tourism
Published November 26, 2003

necessary to ensure the livelihoods of those leaving the agricultural sector and to supplement the incomes of those working in agriculture. I research rural development in four settlements in Hajdú-Bihar County, in Balmazújváros, Hortobágy, Tiszacsege and Egyek, all bordering Hortobágy National Park.
There are many alternative income so...urces in settlements in the Hortobágy area, such as organic farming, production herbs, hungaricums, small animals and arts and crafts, as well as rural tourism. Rural tourism is not for subsistence, but a supplementary income source, mainly available during the summer time. I made a survey of rural hosts in the four examined settlements, and according to my results, I constructed a model reflecting the cost-benefit relation, as well as the payment period conditions of rural tourism. I am going to show whether it is worth dealing with rural tourism, and if yes, under what conditions. Rural tourism contributes to the maintenance of rural modes of living, in this way it has significant cultural, economic, ecological and social aspects, as well. It is crucial for settlements to create the appropriate conditions needed for joining rural tourism, if it is worth joining at all, and to realise investments for all these. Rural tourism has strict requirements for the levels of environment, infrastructure and services. Studying the Western-European practices, Hungary is lagged behind in the conditions of rural tourism and rural hosts have done their activities mainly out of necessity and not to maintain traditions. Rural tourism may result in success only by co-operation and over the long-run.
