  It can be told about the second half of the XXth century that, apart from preferring the large-scale growing of field plants and the largescale
  livestock farming, corresponding to the central political will of the communist era, the significance and innovation output of
  horticultural education in Debrecen was rather of follow-up trait, of secondary importance. The Tobacco Research Institute continued the
  research work, and then even this activity was stopped. According to a survey finished in 1997, the mentioned institute had no invention,
  granted patent, protection for registered model or any application for patent in progress at the Hungarian Patent Office. Until this time, invention activity at the University of Agricultural Sciences was of medium standard. In the National Patent Office, seven patent applications related to agricultural production and nine patent applications for other fields submitted under the inventors’ names were recorded. In the same period, the Cereal Research Institute (Szeged) led the absolute innovation list of Hungarian agricultural R+D institutions and university education institutes by submitting 164 own patent applications. Both in domestic and international terms, the horticultural innovation conducted at the University of Agricultural Sciences, despite the individual research results and achievements deserving recognition, without appropriate background – remained unnoticed. Let us put it this way: for the past decades, the light of the Debrecen Flower Carnival has not been thrown on the horticultural teachers and researchers of Debrecen.

  The honey bees are essential for the pollination of agricultural plants. The Pannonian honey bee, Apis mellifera pannonica, is native to Hungary, only these subspecies are being bread in our country. The parameters have been separated the pannon and italian honey bee subspecies, the colour of tergit, the cubital index and proboscis length. The morphometric analisys is of special importance because this, on the one hand, shows correlation with honey bee production and on the other hand, the pure morphometric charactersitics is the basis of any potential honey bee export. Mitochondrial DNA and microsatellites are the common methods to define genetic diversity and the separation of subspecies.

  It is shown that for a maize the most effective protector of cadmium and nickel influence was zeastimulin, for a pea – agrostimulin.A protective function of emistim C for both cultures was insignificant. It is set that zeastimulin is influential in the increased metals absorption of a root system, however substantially (on 15% for a nickel and twice for a cadmium) reduces their translocation to above-ground part of plants. Previous treatment of pea seed by agristimulin also intensified the accumulation of nickel roots on 60% and did not influence on cadmium absorption and toxicants translocation to tissues of assimilatory organs. The protector role of growth regulators to cadmium and nickel joint influence shows up in the increase of ascorbic acid maintenance in the roots cells of both species to 34%, where as in leaves – at a maize resulted in the lowering of vitamin С amount (on 28%), but at a pea – increase on 20%.

  The effectiveness the use of new nutrient complexes is studied. It is set that a combination of nutrient complexes with organic and organicmineral nutrition background promotes to good growth and development of plants during the growing season, provides the best parameters of crop yield structure and the crop yield and economic efficiency of spring barley cultivation in the condition of the Eastern Steppe of Ukraine.
