Abstract: In last years, in Fundulea, the temperature increased by 2 degrees Celsius compared to multi-year average over 60 years. Agricultural years 2020, 2021 and 2022 were different regarding climatic conditions and year 2022 was the driest with total rainfalls of 285.4 mm. The amount of precipitations in the growing season of sunflower, from April to September, was 248.6 mm, in year 2020, 273.2 mm in year 2021, 216.3 mm in year 2022 and average of 60 years was 351.8 mm.
The soil water reserve for the 2020 agricultural year, from October 2019 to March 2020 was 135.8 mm, for the 2021 agricultural year it was 278.4 mm, for 2022 it was 150.3 mm and the average the 60-year multiannual was 232.5 mm. In year 2020, average of seed oil content of sunflower hybrids analyzed was 41.11%, in year 2021 was 38.39% and in year 2022 was 40.47%. In year 2020, average of seed yield of sunflower hybrids analyzed was 1775 kg/ha, in year 2021 was 3283 kg/ha and in year 2022 was 3373 kg/ha. Average hectoliter weight (kg/hl) of sunflower hybrids analyzed was 55.2 kg/hl in year 2020, 40.2 kg/hl in year 2021 and 59.3 kg/hl in year 2022. Of all the sunflower hybrids created at NARDI Fundulea and tested three years, the best was FD18E41 in 2022.
