  Irrigation involves the risk of secondary salinization on certain areas. The increase of the level of salty groundwater or the application
  of poor quality (salty) irrigation water can cause secondary salinization. Irrigation from drilled wells is very characteristic in the small
  hobby gardens located around Karcag during the frequently droughty summers. Mainly vegetables and fruits with high water demand are
  grown in these gardens, hence quite a large amount of subsurface waters are used for irrigation. Water samples were taken from 46 drilled
  wells located in the hobby gardens around the town of Karcag and analysed in order to survey the risk of secondary salinization. On the
  base of the results of the analyses and some indexes calculated from the chemical parameters of the irrigation waters, it can be established
  that none of the investigated wells supply water that is suitable for irrigation without improvement.

  There are several extended studies in sweet cherry production in Hungary and all over the world i.e. for creation and maintainence of smaller tree crown and high density orchards. The use of suitable dwarf rootstocks for this fruit species are very limited. On one hand, most of the draf rootstocks do not cause enough growth reduction and on the other hand these rootstocks are get old very quikcly and their fruits become small, and therefore, they not serve the requirements for intensification. In summary, there is a need for those rootstock which are vital, regeneration enhanching and delay ageing. Due to ensuring above features, Prunus mahaleb is still an obvious solution for intesive production. Increasing intensification can be obtained by use of modernisation of technological elements and suitable cultivar choice. 
  According to this increasement of intensity through application of novel technological elements (timing, manner and severity of pruning) and selection of the proper cultivar is implement able. Important differences are experienced between sweet cherry cultivars in their growth attributes, light demand and dynamics of fall back in regenerative potencial of different aged wood parts. From this point knowledge of the abow detailed is very important in order to maintain rentability of already established plantations. Our work shows the formation of production part in
  9-year old plantation with spike spindle and free spindle crown forms depending on pruning timing (winter, summer) and determining of their various effects.
