  With this study, the author intends to draw up the main characteristics of the institutional background of the Farm Accountancy Data Network, operated by the European Union. Among the factors that contribute to the formation of the institutional background of the FADN database, special emphasis is laid on the Commission and member state level legal framework, in order to provide potential Hungarian users of the database with authentic and substantial information. Also, much attention is paid to definitional misunderstandings which cause, or might cause the farm business management type utilization of the database to be imperfect. As for this goal, some of the elements of the FADN information structure are investigated in a conventional Hungarian cost structure. In order to facilitate an easier understanding of the database, the different relations of economic size classes are also reviewed in this study. The author of this study is – in the first place – trying to analyze the meaning of Standard Gross Margin, the index used in the FADN structure to categorize farms, by localizing the position of the different cost constituents of SGM in a conventional Hungarian cost matrix. Last, but not least, the author is trying to draw all researcher’s attention on the possibilities, hidden in the FADN database by introducing some analyses from his own field of interest based on FADN information.

  Hungarian dairy sector went through significant changes in past two decades. The most significant changes were caused by our accession to the European Union. In Hungary milk production remarkably declined after EU accession. The size of our dairy herd has been practically reducing since the political transformation, but increasing yields per cow could compensate it in some way and for some time. However, in recent years, increasing yield per cow came to a stop and in parallel, the number of cows declined further and faster. Low prices, high production costs and tightening quality requirements ousted several producers from the market in past years. Feeding cost represents the highest rate in cost structure of production, but animal health expenditures and various losses are also significant. There are undeniably competitive disadvantages in the level of organisation and labour productivity; however competitiveness already depends on cost effectiveness in the medium run. In Hungary concentration of the dairies is relatively strong in spite of the relative high number of corporations. The dairies compete with each other and with the export market for the raw material and the better exploitation of their capacities. Applied technology of the Hungarian dairies lags behind the Western-European competitors’; in addition they have handicaps in efficiency and product innovation. Presence of chain of stores being dominant in sale of milk products does also not favour in all respects to the position of the dairies. The aforementioned retail chains are namely consumer-centric, engage in price follower conduct and weaken the position of the dairies with their private label products. As a result of increasing import of milk and milk products Hungary became a net importer in recent years. Today, disposable income still essentially determines the consumption habits of price-sensitive consumers. Loyalty for Hungarian products is not typical, consumers are open for import products being preferred by retail chains. In addition Hungarian milk and milk product consumption is about half of the Union average and it is far behind the level being necessary for healthy eating. In Hungary lack of competitiveness and vertical integration relationships and backwardness are revealing among the dairy farmers and the dairies, while chain of stores are in unprecedented “monopolistic situation”; the whole sector can be characterised by defencelessness.

  The successfulness of crop production is significantly affected by not only the the average yields that provide cost effectiveness, but also the success of striving for yield safety, therefore, varieties and hybrids tolerant to environmental stress factors are worth being included into the sowing structure. Our aim was to further the decision making of producers in prepaering the right sowing structure by the evaluation of sweet maize hybrids’ tolerance to excess rainfall.
  We performed our examinations in an extremely wet year (2010) on chernozem soil on three sweet maize hybrids (GSS 8529, GSS 1477, Overland) in 12 replications. Comparing the yields of 2010 with those that can be expected under optimal rainfall conditions, we showed that the examined hybrids react to the amount of rainfall higher than their needs with yield depression. The excess rainfall tolerance of the examined hybrids is different in the case of each hybrid.

  technical and economic characteristics, which give rise to high levels of uncertainty and greater control in the supply chain. In order to investigate the role of different transaction costs in marketing behavior, we carried out research in the central region of Hungary among beef retailers and wholesalers. This research is based on primary data collection and examines the motivation of choices in the beef sector on distinction among different marketing channels and the role of transaction costs in procurement. Since this case can be regarded as a qualitative choice situation the hypothesis that transaction cost’s variables are significant is judged by the application of multinomial logit model in order come up with the variables that can influence the supply chain structure and the choice of different marketing channels. This analysis enabled us to explore the structure in data and confirm or reject the expected interrelations of causative variables. Our

  ZigBee technology aims to completely satisfy the requirements set by precision agriculture, since this system makes it possible to collect data in an accurate and regular way. The cost of one module is rather favourable; therefore, damaged parts can be replaced quickly. Due to the modular structure, the system can be further developed easily. New units can be quickly incorporated into the network without any difficulty.

  In this study, the effects of freeze drying (FD), hot-air drying (HAD) and combined drying (HAD-FD) on drying characteristics, energy uptake, texture, rehydration and color of carrot were investigated. Results showed that HAD-FD significantly improved the drying time compared with FD under the same operating conditions, and the HAD-FD can reduce the total cost of dehydration. The drying kinetics was described by the Henderson-Pabis and the third degree polynomial models in the case of HAD, FD and HAD-FD. The HAD carrot samples were exhibited shrinkage, case hardening, poor rehydration and brown surface. The FD carrot cubes appeared porous structure, excellent rehydration, soft texture and loose color. The HAD-FD samples were superior to HAD products and was nearer in quality to FD products with respect to appearance, rehydration and surface resistance (texture). Finally, it is concluded that HAD-FD is effective in improving the FD drying rate. However, the combined drying has a small-scale adverse effect on product quality.
