Evaluation of Camelina (Camelina sativa) Genotypes Grown in Winter at Different Sowing Dates in Northern Turkey Ecological Conditions in Terms of Yield and Oil Ratio

This research was conducted to determine the effect of sowing dates on the yield and oil ratio of Camelina genotypes. The research was conducted in Northern Turkey during the 2017-2019 growing season with the use of 4 sowing dates (23 October, 3 November, 13 November, and 23 November) and two camelina genotypes (PI-650142 and PI-304269). Yield varied between 0.90-1.76 kg ha-1 and oil ratio between 28.4-30.8%. It was concluded based on present oil ratio findings that the second sowing date (3 November) was more suitable for camelina cultivation in the winter season in Northern Turkey ecological conditions, while it was concluded based on present yield findings that the fourth sowing date (23 November) was more appropriate. PI-650142 genotype seemed to be more adaptable to ecological conditions of Northern Turkey in terms of investigated oil ratio, and PI-304269 genotype can be preferred in terms of yield. Advancing or delaying sowing dates could have adverse effects on yield and yield components of the camelina genotypes.
