The field experiment was corried out in the experimental selected area in Dropla village (North-East Bulgaria) in the period 2012 - 2014. The test was performed by means of a block method with four repetitions; experimental field area - 25 m2 after winter wheat predecessor. The following sunflower hybrids were tested; Kondi, Neoma, Adajhio, Alego and PR64F50. The aim of the investigation was to determine the potential of yield of the tested sunflower hybrids in the region of North-East Bulgaria. The analysis of the results showed that the highest values of elements of productivity were reported with the hybrid Neoma and the lowest – with the PR64F50 hybrid. Hybrid Neoma was most suitable for growing under the conditions of North-East Bulgaria; it gave maximum mean seed yield (3523 kg/ha) and oil yield (1742 kg/ha) during the three years of testing. This was the hybrid with highest mean crude fat content – 49.3%. Lowest seed and crude fat seed yields were obtained from the Alego hybrid (3160 and 1456 kg/ha).
