Vermicompost, which is not harmfull to the environment, and is increasing in agricultural production in terms of both gaining to the soil and benefiting the waste. This research was carried out in 2019 in Bayburt ecological conditions in order to determine the impacts of different doses of solid (250, 500 and 750 kg da(-1)) and liquid (0, 250, 500 and 750 ml da(-1)) vermicompost fertilizers on the flowering and maturation period (days), stem diameter (cm), table diameter (cm), plant height (cm), thousand weight (g) seed yield (kg da(-1)), seed internal rate (%) oil ratio (%) and oil yield (kg da(-1)) of sunflower (Helianthus annuus). In the experiment, it was determined that all parameters were statistically significant compared to p<0.01. The highest seed (218.7 kg da(-1)) and oil yield (75.9 kg da(-1)), which are the most important parameters in oil sunflower, were obtained in 750 kg da(-1) solid and 750 ml da(-1) Liquid vermicompost application (K3S3). As a result, the use of solid and liquid vermicompost application in oil sunflower together will be beneficial in obtaining the highest healthy, high quality seed and oil yield.
