In order to investigate the effect of drought stress and planting date on the quantitative and qualitative yield of Camelina, this experiment was conducted in the crop year of 2021 in the form of a split plot in the form of a statistical design of complete blocks in three replications. In the main plots, three levels of planting date (October 30, November 14, and December 16) were compared, and in the secondary plots, drought stress was compared at three levels (90, 55, and 25 percent of field capacity). The results showed that the effect of drought stress and planting date on the number of corns in the main and sub branchs, 1000-grain weight, biological yield, harvest index, seed yield and oil yield were significant. The highest seed yield (1.83 ton/ha) and 1000-grain weight (1.67 g) on the planting date of November 14 and irrigation at the level of 90% of the field capacity and the lowest seed yield (0.26 tons per hectare) and 1000-grain weight (1.13 g) on the planting date of November 16 with irrigation at the level 25% of the farm capacity was obtained. In moderate stress conditions, the highest correlation between harvest index and 1,000-grain weight was obtained with grain yield, and in severe stress conditions, harvest index and biological yield showed a high correlation with seed yield. In general, the planting date of November 14 can be considered suitable for increasing the seed yield and oil yield of Camelina plant under irrigation conditions of 90% of the field capacity.
