This study was carried out in irrigated conditions during the summer growing season of 2020 and 2021 to determine the effects of biofertilizer applications and inorganic fertilization on some quality and biochemicals properties of safflower (Carthamus tinctorius L.) in Van ecological conditions. The experiment was set up as a randomized block design in 3 replicates at the Faculty of Agriculture, Van Yüzüncü Yıl University. The mixture of five different biofertilizers (Frateuria aurantia (B1), Bacillus megaterium (B2), Azospirillum lipoferum (B3), Chlorella saccharophilia (B4), and a mixture of Lactobacillus casei + Rhodopseudomonas palustris + Saccharomyces cerevisiae + Lactococcus lactis microorganisms (B5)) different NP (nitrogen+phosphorus) fertilizer doses (control, 100% NP (NP100) as full dose (optimum) 15 kg of pure nitrogen (Ammonium sulfate (21%) and 8 kg of pure phosphorus (TSP (42%)) per decare); % 7.5 kg of pure nitrogen (Ammonium sulfate (21%) and 4 kg of pure phosphorus (TSP (42%)) were applied as 50 NP (NP50) reduced dose per decare. Some quality and biochemical Parameters including petal yield, crude oil rate, crude oil yield, total dyestuff ratio, total phenolic substance content, total flavonoid substance content and total antioxidant activity were measured. According to the results of the research; In both experimental years, the best results for crude oil yield and petal yield were obtained from NP100 applications, while the best results for total flavonoid substance content and total antioxidant activity were obtained from NP0 applications. B4 biofertilizer applications for crude oil ratio, B1 biofertilizer applications for petal yield, and B5 biofertilizer applications for total phenolic content were the biofertilizer applications with the best results in both years.
