  Precision farming has an array of technological equipment, elements and complete systems which are in themselves suitable to create conditions for efficient farming, to reduce environmental load and to provide farmers with optimal return on their investment.

  On the leading edge of my research is to introduce the economic benefits of precision logistic optimization with satellite navigation in wheat and maize harvesting. My hypothesis, claiming that a well-organized system can increase the number of working days by 4 days per harvesting season in maize, and 2 days in wheat crop. If the farmer makes contract works for harvesting it means for him 2 or 4 days extra work by using the precision farming technologies with satellite communication system. Overall, as pertains to wheat and maize harvest seasons, yearly revenues can be increased by 7 760 000 HUF. I would like to introduce that the precision technologies increase combine costs by merely 5.4% which can be return in the first year of using.

  In the trade of the European Union principally the analysis of alveographical and extensographical parameters mean the acceptance system.
  In the present study we analysed the extensographical parameters of 10 winter wheat varieties breed by the Cereal Research Non Profit Company with Brabender extensigraph and we made a comparison, correlation among the results. The examinations with Brabender the following among: show the GK Kalász and the GK Élet varieties show high resistance of extension and the GK Petur variety produces high extensibility. The GK Garaboly has shown low extensibility and energy. The other parameters had different values in the examined three years. The measurings with SMS2 Texture Analyser show middle positive correlation between extensibility and subarea. There are weak correlation between at the significantial level in the 90, 135 resistence of extension by Brabender and by SMS2 Texture Analyser and in the 45 extensibility by Brabender and by SMS2 Texture Analyser of relaxed dough. There is no correlation among other parameters.

  We analysed the crude protein content, amino acid content, amino acid composition of four forage and milling III. quality winter wheat varieties (Magor, Hunor, Róna and Kondor) from their samples from five following years (2003, 2004, 2005, 2006, 2007). We found that quantity of essential and non-essential amino acids rose with increase in crude protein content. On examination of protein amino acid composition in relation to crude protein content we found that the crude protein content increased the quantities of the non-essential amino acids also rose, while those of the essential amino acids decreased as the lysine, the limiting amino acid of wheat. We also established that, as crude protein content increased, the biological value of the protein decreased.

  Wheat is one of the most important cereals in the world and the bread made of its flour belongs to the everyday life of human  mankind.
  The Hungarian standard relating to the laboratory production of wheat flour (MSZ 6367/9-1989) does not mention the type of laboratory mill used for milling, and it only builds up some general criteria, such as: the laboratory mill should be provided  with four differently nicked barrels, a sieve with appropriate hole sizes, and also with the separated collections of the pilot flour and the bran. Our study was started at this point and the answers for the following questions were aimed to be found: do the flour patterns studied and produced with different sieving techniques, 
  widely used in laboratory mills of the same wheat pattern show any alterations after the impact of the formula production as regards chemical constitutions. Various flours of the wheat pattern sieved with different particle sizes were studied in this experiment. 
  In producing this pattern we used FQC109 type of mill. There were 5 different corn sizes of 250-200; 200-160; 160-125; 125-100; <100 μms used in the partition of the fractions. The results this research confirm that the quality of wheat flour can be modified by different methods of pattern production.

  Nowadays, many methods have been worked up in the interests of objective expression of winter wheat rheological quality. These define wide spectrum in view of their complexity and apparatus claim. The needs for the methods are definitely increasing in Hungary, too. It is very important to get acquainted with the alveographical quality and qualification and also their using in wide range.
  In our research we examined the alveographical parameters of 12 winter wheat varieties in Szeged (in Hungary) on the basis of the results in three years (2005-2007).
  We established with correlation analysis that there is no statistical relation between the alveaographical W and G values. The other alveographical parameters have significant correlation.
