In the current research, the simultaneous application of 0, 5 and 10 tons per hectare of vermicompost organic fertilizer and biochar on growth and grain yield of Camelina sativa as a factorial experiment based on a randomized complete block design with three replications in East Azarbaijan province (crop year 2020-2021) was evaluated. The highest oil yield (1073 kg/ha) was obtained in the application of 10 tons of vermicompost and 10 tons of biochar per hectare, which increased the yield of camelina oil by 18.8% compared to the control. This increase was due to the increase in oil content (38.27%) and grain yield (2805 kg / ha). The highest harvest index in the treatment of 10 tons of vermicompost per hectare + 10 tons of biochar per hectare, the highest biological yield in the treatment of 10 tons of vermicompost per hectare + 5 tons of biochar per hectare and the highest number of seeds per silique were obtained in 5 tons of vermicompost per hectare + 10 tons of biochar per hectare. Increasing the number of siliques per plant and the number of seeds per silique by using biochar and vermicompost ramped up the grain yield. In this study, the use of 5 tons of biochar and 10 tons of vermicompost reduced the amount of saturated fatty acids (42%), but, at the some time, the amount of polymeric unsaturated fatty acids was increased (7.27%). According to the results, the application of 10 tons per hectare of vermicompost and biochar is recommended to improve economic yield of camelina plant under rainfed conditions, and considering the highest grain and oil yield was obtained at the highest level of fertilizer used, so additional research is recommended to determine the best level of fertilizer.
