This paper presents the results obtained at SCDA Șimnic for a period of 3 years (2021-2023) regarding the behavior of 10 sunflower hybrids following multi-year tests to identify the most suitable hybrids for the study area. The studied hybrids behaved differently from year to year. The best results were obtained in 2021, followed by 2023, and in 2022 the lowest productions were recorded due to the lack of precipitation and high temperatures in June and July that created unfavorable conditions during the flowering and seed formation period. Average yields of the studied hybrids ranged from 1071 kg/ha (FD15CL440) to 1381 kg/ha (HS8232). Hybrid HS8232 was the only hybrid that significantly exceeded control (media) production. Hybrids HS8232, HS5440 and HS8566 had the lowest coefficients of variation. The evaluated productivity elements had low values as a result of the climatic conditions recorded during the experimentation period.References
