Abstract:

Our country's climate shows great changes both in time and space. These changes are also reflected on agriculturalproductions that also sometime presents substantial differences from one year to another and from one area to another.Based on statistical analyses on large arrays of years, it results that in Romania, the dry years are in very highproportion going up to 70%.For getting to knowing requirements from water of major agricultural crops, by the study achieved mainly thenecessary dimensioning of water for irrigations using the climate deficit method has been considered.From the chronological sequence analysis of years, under the climatic deficit, the change of this in a positive way thatleads to the need for irrigations is come out. Given the set of climatic parameters, the model that approximates the bestthe evolution tendency as some parametrical equations has been studied. Since 2009, for the next 57 years the trendline of the evolution of climatic deficit is clearly increasing in the months May-August.
