Examination of French bean on organic and conventional farming of Research Centre of Nyíregyháza
87-98Views:74This 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 made 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
155-160Views:88Organic 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 goal 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. -
Economic Aspects of Winter Wheat and Sunflower Production Under Organic Farming Methods
256-261Views:84On 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 basis 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.

Comparing the yield of maize (Zea mays L.) hybrids in organic and conventional agriculture
13-17Views:60The European Green Deal was published by the European Commission in 2019. The main aim of the program is to reach net zero greenhouse gas emissions by 2050, making Europe the first climate-neutral continent in the world. To achieve this, criteria are also set for agriculture: increasing the share of land under organic farming to 25%, reducing the use of fertilisers and pesticides. However, the benefits of organic farming are widely debated. The aim of our study was to compare the yield of maize (Zea mays L.) hybrids bred in Martonvasar in two different cropping environments. The silage yields of 20 different maize hybrids were evaluated in a three replicate small plot experiment in an organic field and an adjacent conventional field. The average green mass yield of the hybrids was 36,58 t ha-1 in the organic field and 43,03 t ha-1 in the conventional. The green mass yield in the organic area was 20% lower than in the conventional area, and the dry matter yield and digestible dry matter yield were about 18% lower. Hybrids of different maturity groups responded differently to organic cultivation. The yields of early hybrids decreased more and late hybrids less in the organic farming compared to the conventional production.

Stripe rust reaction and yield response of winter cereals in bio - versus conventional farming
47-50Views:118In 2014, was an extremely early and heavy yellow rust (Puccinia striiformis var. striiformis) epidemic in Hungary. Significant differences were among locations, years and genotypes in the severity of infection. Ratio of the resistant and moderately resistant genotypes was higher under bio environment. The yellow rust epidemic caused significant yield decreasing in the tested winter cereals.

Current Conditions and Opportunities of Biofarming in Hungary
150-156Views:85The 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 nature 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.
