The effects of spring and autumn planting seasons on grain, biological, and oil yields, oil percentage, and yield based on water consumption were investigated in a factorial experiment as a randomized complete block design with three replications in the central district of Fasa city, Fars province, during the crop year of 2018-2019. Five Camelina lines (133, 132, 131, 80, and 114) were the main factor and two planting dates of February 20 (spring planting) and November 1 (autumn planting) were considered as secondary factors. All the studied traits were affected significantly by the planting date. The highest average grain, biological, and oil yields (67.2267, 00.5184, and 27.666 kg/ha, respectively) and the coefficient of oil extraction (53.29%) belonged to autumn crops. Spring crop gained a grain yield of 0.49 kg/ha/m³ based on water consumption. The lines were not different statistically in the percentage of extracted oil. L 114 gained the highest amounts of these traits in spite of no significant differences with L 131 in all the measured traits. Significant interactions of different lines and planting date in spring and autumn crops indicated that L 114 had the highest amounts of the measured traits in the autumn crop, except the grain yield based on water consumption. The highest average grain yield based on water consumption (60.0 kg/ha/m³ belonged to L 131 in the spring crop, which was not different significantly from L 114 with an average of 54.0 kg/ha/m³. Lines 132, 133, and 80 gained the lowest levels of the measured experimental traits and contained the lowest grain and biological yields. These three lines were not different statistically in the comparison to the average oil yields in spring and autumn crops.
