The heat and water stress always bring about a diminishing of yields, the magnitude of it being influenced by the duration and the intensity of the stress phenomenon. Sunflower is a drought tolerant species yet long term water shortage can inflict damages in the growing and development of the sunflower plant. The present paper deals with 5 sunflower hybrids of German origin in the soil and clime conditions of ARDS (Agricultural Research and Development Station) Simnic (Dolj) in the „extremelly” dry year 2007 and during 2008 year which was considered dry. There were recorded reductions of the vegetation phases, of productivity elements as well as of seed yield. The best yield was given by Enduro hybrid and this hybrid is recommended for extension and further studies in this area and simmillar areas.
