Sunflower is one of the most important oilseed crops on a global scale. The aim of the present study was to determine the productivity of four sunflower hybrids and to establish the influence of the factor hybrid in accordance with the specific climatic conditions of the year on the seed yield, as well as on some qualitative and quantitative indicators. The experiment was conducted during the period 2021-2023 in the region of Targovishte on soil type chernozem and an experimental area of 25 m2 in four replications, after predecessor wheat. The following hybrids sunflower were tested:
“P64LE136”, “LG 50.549 SX”, “Subaro” and “P64HE118”. The results showed that the tallest plants were formed from P64LE136 hybrid and the lowest one - from LG 50.549 SX. The highest values of head diameter (20.4 cm), number of seeds per head (1513), seed weight of head (240.0 g), seed yield (3593 kg/ha) and 1000 seed weight (204.0 g) was reported for Subaro hybrid. Hybrid LG 50.549 SX was distinguished by the highest values of oil content (48.4%) and oil yield (1548 kg/ha) as well as test weight (43.2 kg).
